Essential tremor
It is the most frequent movement disorder in adults, and probably the one that is talked about worst. It is called benign, when it stops someone drinking a coffee in public; it is confused with Parkinson's disease, when it is almost its exact opposite; and rehabilitation is offered without saying what it can really do. This article deals with those three points: recognising it, measuring what it costs the patient, and stating honestly the little that physiotherapy can bring. For the parkinsonian side of the differential diagnosis, see Parkinson's disease and the parkinsonian syndromes.

Essential tremor in three figures
A very common condition after the age of 65, often mislabelled, and one that takes up far more of the patient's day than parkinsonian tremor does.

In brief
- It is an action tremor, and that is what makes it disabling. It is absent when the hand is doing nothing, and appears precisely when the hand is being used: carrying a glass, holding a spoon, writing, aiming for a light switch. Parkinsonian tremor does the opposite.
- It is very common, and its frequency rises sharply with age. Pooled prevalence reaches 5.79 % after the age of 65, with a median of 9.3 % in the oldest age bands and several studies above 20 % 2.
- It is overdiagnosed. In a series from a specialist centre in London, only half the patients labelled with essential tremor matched the defined phenotype, and one fifth had another established diagnosis 3.
- Its burden is as social as it is motor. Beyond the tremor itself, the literature review describes dependence for everyday tasks, an increased risk of falls, anxiety, embarrassment and a sense of being diminished 6.
- Alcohol genuinely relieves it, but the patient is a poor judge of that. A standardised challenge finds an objective response in 80 % of patients, whereas the response they report correlates poorly with the response measured 8.
- The effective treatment is not a rehabilitative one. Propranolol and primidone are rated clinically useful; surgery and focused ultrasound come next 9. No evidence-based review retains any physiotherapy intervention.
- What rehabilitation can do is real, but narrow. Strengthening reduces postural tremor and improves dexterity in older people, essential tremor included 13 ; cooling the limb transiently improves hand function 15. The samples are small and the effects transient: saying so clearly is part of the care.
What is essential tremor?
A syndrome defined by what it is, but also by everything it must not be.
The international classification of tremors defines tremor as an involuntary, rhythmic, oscillating movement of a body part, and classifies it along two axes: clinical features on one side, aetiology on the other 1. Within that framework, essential tremor is an isolated tremor syndrome : a bilateral action tremor of the upper limbs, present for at least three years, with no other neurological sign.
The word isolated carries the whole weight of the definition. As soon as a subtle neurological sign is added (a mild dystonia, an abnormality of tandem gait, a memory problem), the classification speaks of essential tremor plus. That category, introduced in 2018, is debated: several studies have shown that reclassification moved a substantial share of patients from one category to the other depending on how carefully the examination was done 23, and its interpretation remains disputed 22.
A common condition, and one that becomes more so with age
The most complete meta-analysis pooled 42 population studies conducted in 23 countries across six continents 2. Pooled prevalence, all ages combined, comes to 1,33 %. But that overall figure says almost nothing about the patient seen in the clinic, because prevalence rises by 74 % per decade of age.
After the age of 65 it reaches 5,79 % in meta-analysis, with a median crude prevalence of 5.9 % and a mean of 8.0 %. In the oldest age bands, the median rises to 9.3 %, and several studies exceed 20 %. The authors close with a striking comparison: the prevalence of essential tremor after 65 is of the same order as that of Alzheimer's disease in older people. Sex does not influence prevalence.

Four markers to frame the condition
A tremor that is unremarkable in the general population, whose diagnosis is nevertheless often inaccurate, and whose sensitivity to alcohol is quite real.

Overdiagnosis, a problem documented for twenty-five years
A study conducted at the National Hospital for Neurology and Neurosurgery in London reviewed 50 records of patients labelled with “essential tremor” by various neurologists, and checked how many matched the classic phenotype described in the literature 3. The result: 25 patients out of 50, that is half. Ten clearly had another diagnosis, among them an associated dystonia in four of them and a neuropathic tremor in two.
This finding is not a historical curiosity: it explains why a patient referred for “rehabilitation of an essential tremor” deserves to have the tremor looked at directly before a plan of care is built. A dystonic tremor, a neuropathic tremor or an early parkinsonian tremor call for neither the same advice nor the same referral.
Key point
Essential tremor is defined as much by what it is (a bilateral action tremor of the upper limbs, present for at least three years) as by what it excludes: any other neurological sign. In practice, two things are enough to raise the question: have the patient hold their arms out, then have them bring a glass to their mouth. If the tremor only appears there, and the hands resting on the thighs are still, we are in the right frame.
How do you tell it from a parkinsonian tremor?
It is the question patients ask first, often anxiously, and it is settled in the clinic.
A patient who tremors rarely arrives neutral: they come because they are afraid of having Parkinson's disease. Knowing how to answer means knowing the four things that genuinely separate the two pictures, and knowing which ones do not settle it.
First: when the tremor appears
This is the decisive criterion, and it takes thirty seconds to observe. Essential tremor is an action tremor: postural when the arms are held out in front, kinetic when the hand moves towards a target. It is absent or minimal when the hands rest, fully supported, on the thighs.
Parkinsonian tremor does the opposite: it appears at complete rest and fades as soon as the limb engages in a voluntary movement. That is why a parkinsonian patient who tremors a great deal in the waiting room can drink their glass without difficulty, whereas a patient with essential tremor, whose hands are still at rest, will spill it.
This difference has a numerical translation in lived experience. Asked how many waking hours they spend with tremor, patients with essential tremor report a median of 10 hours against 3 hours for parkinsonian patients, that is more than three times as many 4. A higher number of hours was associated with female sex, higher depression scores, a heavier perceived disability and, in essential tremor, a higher social embarrassment score.
The same movement, two opposite behaviours

Built from Bhatia et al., Mov Disord 2018 (PMID 29193359) and Postuma et al., Mov Disord 2015 (PMID 26474316). The heights illustrate a clinical principle, not measurements.
Second: asymmetry
Parkinson's disease begins on one side and stays that way for a long time. Essential tremor is usually bilateral, which is even part of its definition. That does not mean it is perfectly symmetrical: recent cross-sectional and longitudinal data show that moderate asymmetry is common in essential tremor 26.
The practical rule therefore comes down to a nuance: a clear and persistent asymmetry, especially with a rest tremor, points to a parkinsonian syndrome; a moderate asymmetry on a bilateral action tremor remains compatible with essential tremor.
Third: the response to alcohol
The sensitivity of essential tremor to a small amount of alcohol is a long-known feature, and it is real. A standardised challenge study with objective measurement found a response in 80 % of the patients tested 8. The size of the response correlated with the measured blood alcohol level, but not with sedation, which indicates a specific effect on the tremor rather than simple relaxation.
The point everyday practice rarely takes away is nevertheless the most useful one: the response the patient reports does not match their objective response well. A negative history therefore does not rule out the diagnosis, and a positive one does not confirm it. It must also not be turned into advice: nothing in these data justifies recommending alcohol as a treatment, and the risk of misuse in patients who feel embarrassed in company is real.
Fourth: what accompanies the tremor
This is where the physiotherapist contributes most. Essential tremor is, by definition, an isolated tremor. The presence of bradykinesia with decrement (amplitude falling away over twenty hand opening-and-closing movements), of rigidity, of hypomimia or of reduced arm swing when walking takes it outside the frame and calls for a neurological opinion 27.
Handwriting gives a further clue in ten seconds. Parkinson's disease produces micrographia : clear letters that get smaller along the line 28. Essential tremor produces large, wavyhandwriting, with letters of preserved size but an irregular stroke. An Archimedes spiral, drawn without resting the wrist, separates the two at a glance.
| Feature | Essential tremor | Parkinson's disease | Value in settling it |
|---|---|---|---|
| Tremor at rest, hands supported | Absent or minimal | Present, characteristic | High |
| Tremor with arms held out and on movement | Present, troublesome | Often reduced | High |
| Bradykinesia with decrement | Absent | Required for the diagnosis | High |
| Handwriting | Large, wavy, size preserved | Micrographia, clear stroke | Good |
| Asymmetry | Moderate, frequent | Clear, lasting | Moderate |
| Response to alcohol | Objective in 80 % | Absent | Moderate, the history is unreliable |
| Family history | Frequent | Possible | Low |
| How long the tremor has been present | Often decades | Months to a few years | Moderate |
| Tremor of the head or voice | Possible | Rare, the voice is more often weak and monotonous | Moderate |

The trap of both diagnoses at once
The two conditions are not mutually exclusive. The classification recognises intermediate pictures, and a specialist clinic series has compared the phenotypes of isolated essential tremor, essential tremor plus and forms associated with Parkinson's disease 21. In a patient followed for years for essential tremor, the later appearance of a clear rest tremor, of a slowness that fades away or of marked asymmetry is therefore not a contradiction: it is a reason to refer again.
And the diagnosis, in doubtful cases?
When the picture stays ambiguous, dopamine transporter imaging allows a tremor of dopaminergic origin to be separated from one that is not. It is a second-line investigation, prescribed by the neurologist, and it is not needed in typical pictures. It is worth knowing it exists, in order to understand the journey of a patient who comes back from it, and not to be surprised that a patient followed for essential tremor has been referred to nuclear medicine.
Faced with a tremor, the useful question is not “is it serious” but “when does it appear”. The answer to that single question correctly directs the great majority of patients.
Which other tremors can it be confused with?
Half the labels being inaccurate, it is worth knowing the main competitors.
In the London series already cited, of the 50 patients labelled with essential tremor, ten had an established alternative diagnosis, of whom four an associated dystonia and two a neuropathic tremor 3. The international classification provides the framework for not getting lost: it describes tremor syndromes , defined by the combination of the tremor and of what accompanies it 1. The recent reference reviews take up the same approach 25.
| Tremor | What distinguishes it | What that changes |
|---|---|---|
| Enhanced physiological tremor | Fine, fast, of recent onset. Context: anxiety, caffeine, exertion, withdrawal, hyperthyroidism, hypoglycaemia, a recently started drug (beta-agonists, corticosteroids, lithium, valproate). | Often a reversible cause. Asking about medication and how long it has been present is enough on its own to point the way. Refer for investigation rather than rehabilitate. |
| Dystonic tremor | Irregular, more marked in certain positions and eased by an antagonistic gesture (the well-known sensory trick). Often associated with an abnormal posture, particularly of the neck. | Management belongs to dystonia, covered in the article Focal and generalised dystonias. Botulinum toxin has a place there that essential tremor does not give it in the same way. |
| Cerebellar tremor | Slow, intention tremor, clearly amplifying as the target is approached, with dysmetria and other cerebellar signs. | A different picture and different rehabilitation, developed in the article Cerebellar ataxia. |
| Parkinsonian tremor | At rest, fading on movement, asymmetrical, accompanied by bradykinesia with decrement. | Neurological opinion. See Parkinson's disease and the parkinsonian syndromes. |
| Neuropathic tremor | Associated with a distal sensory deficit, areflexia, impaired deep sensation. | Peripheral neurological assessment takes priority. Look for signs of a polyneuropathy. |
| Functional tremor | Often abrupt onset, variability of frequency, distractibility (the tremor lessens or changes when attention is directed elsewhere), entrainment to a rhythm imposed on the other hand. | A positive diagnosis, made by the neurologist, and not a diagnosis of exclusion. Management is specific and how it is explained is decisive. |

The trap of the isolated tremor that is not
A diagnosis of essential tremor requires the tremor to be isolated. Yet the signs that disqualify it are subtle and are seen only if looked for: a slight tilt of the head, a sensory trick the patient has adopted without naming it, a few missteps on tandem gait, minimal dysmetria. The physiotherapist is well placed to spot them, because they observe the patient moving and over time, in conditions a consultation does not reproduce.
What essential tremor “plus” means
When those subtle signs exist without amounting to another diagnosis, the classification speaks of essential tremor plus 1. That category is debated: a reclassification study showed that it absorbed a substantial share of patients previously labelled with simple essential tremor 23, and its statistical interpretation has been questioned 22. A specialist clinic series has compared the phenotypes of the three groups: isolated essential tremor, essential tremor plus, and association with Parkinson's disease 21.
For day-to-day practice the stakes are modest: this distinction does not change how rehabilitation is conducted. It matters mainly because it is a reminder that essential tremor is not a perfectly homogeneous entity, and that a patient whose picture is filling out deserves to be reassessed rather than simply followed.
What is the real functional burden?
It is called benign because it does not shorten life. That is not what “benign” means to the patient.
Essential tremor has long been presented as a monosymptomatic condition of no seriousness. That description is misleading on two counts: it underestimates the disability of everyday tasks, and it ignores a psychosocial impact that is sometimes the real reason for the consultation.
What tremor severity costs, measured
A real-world study examined the links between tremor amplitude, activities of daily living and quality of life, using the TETRAS scales 5. The association between upper limb tremor amplitude and the activities of daily living score is strong (r = 0.761). The associations with the two quality of life scales are moderate: r = −0.410 for the EQ-5D-5L and r = 0.457 for the QUEST questionnaire, and impairment of daily activities itself predicts quality of life (r = −0.543).
The practical reading of these coefficients is instructive. Tremor severity explains the disability of everyday tasks well, but quality of life markedly less well: between the two sits everything that cannot be measured with a ruler, embarrassment included.
Tremor amplitude explains the tasks, less so quality of life

What weighs beyond the tremor
A systematic review of 39 studies looked precisely at what is not the tremor 6. Patients show more marked disability and reduced independence compared with healthy subjects, struggle to carry out daily activities and rely on those around them for physical and emotional support. Added to that are movement and balance disorders, an increased risk of falls, depression, anxiety, poor sleep, and psychosocial consequences the authors name explicitly: embarrassment, apathy and a sense of being diminished.
Key point
A patient may consult for a tremor whose amplitude looks modest, and be deeply troubled by it. The question that really opens the interview is not “how bad would you rate your tremor” but “what have you stopped doing”. Drinking in public, writing a cheque in front of someone, eating soup in a restaurant, putting on make-up: what people give up describes the disability better than any rating scale.
The non-dominant arm matters more than you think
Clinical attention goes naturally to the dominant hand. A study of 181 right-handed patients tested that habit 7. Independently of right-sided tremor, greater severity of left -sided tremor was associated with greater self-reported disability (p = 0.02) and with more marked measured dysfunction (p < 0.001). In 5.0 % of patients the tremor was even essentially confined to the non-dominant arm.
The reason is obvious once stated: most everyday actions are bimanual. Steadying a plate, holding a jar being opened, keeping still a paper being signed. Assessing and treating both sides is therefore not excessive zeal.
Writing, drinking, eating
Essential tremor varies with the task, and that variability has been measured: amplitude is not the same depending on the movement asked for, which explains why a patient can pass one test and fail the neighbouring one 29. In practice, this argues for assessing the patient's real tasks rather than standardised items alone: have them drink from their own glass, write with their own pen, carry a spoonful of water.
Does essential tremor also affect gait and balance?
Yes, and it is probably the area where the physiotherapist has most to offer.
This is a poorly known point, and yet the one that gives physiotherapy its best justification in this condition. A review of 23 articles on gait and balance in essential tremor reaches clear conclusions 18. The prevalence of balance disturbance, measured by missteps on tandem gait, is seven times higher in patients than in controls. Gait is slower, more asymmetrical, and dynamic balance is impaired.
These problems worsen with age, but patients remain more affected than controls independently of age : this is therefore not simple ageing. The profile is qualitatively close to that of the spinocerebellar ataxias, which fits the cerebellar pathophysiological hypotheses of essential tremor, and the authors stress that these impairments are not subclinical: they translate into more near-falls and into real functional difficulties. The parallel with cerebellar pictures is developed in the article Cerebellar ataxia.
The factors associated with these problems have been identified: age, the presence of a midline tremor (head, voice, trunk) and poorer cognitive functioning. An earlier study had already linked tandem gait performance to these midline tremors 19. A further argument for a causal link comes from neurosurgery: gait ataxia in essential tremor is modulated by thalamic stimulation, in one direction or the other depending on the settings 20.

Red flags for this chapter
In a patient followed for essential tremor, these features should lead to a neurological opinion:
- The appearance of a clear rest tremor, hands fully supported.
- Slowness with decrement on rapid alternating movements, rigidity, hypomimia, loss of arm swing on one side.
- Asymmetry that increases markedly, when it was moderate and stable.
- Clear ataxia, a widened base, dysmetria on finger-to-nose: the picture leaves the isolated tremor frame.
- Rapid onset, over weeks or months, in a patient who had nothing: consider a drug, toxic or metabolic cause.
- An associated abnormal posture, head tremor with a torsional attitude: consider a dystonic component, developed in the article Focal and generalised dystonias.
Which treatments, and with what results?
The physiotherapist does not prescribe them, but does support patients who take them, hesitate to take them, or expect too much of them.
The evidence-based review published by the Movement Disorder Society in 2019 examined 64 studies of pharmacological and surgical interventions 9. Both propranolol and primidone are rated clinically useful there, as is topiramate at doses above 200 mg a day. Alprazolam and botulinum toxin type A are judged possibly useful. On the interventional side, unilateral deep brain stimulation of the ventral intermediate nucleus, radiofrequency thalamotomy and MRI-guided focused ultrasound thalamotomy are also rated possibly useful. All these recommendations concern limb tremor: for the voice and the head, the evidence was judged insufficient.
An update that cools the certainties
The same learned society republished an updated review in 2026, restricted to randomised trials with at least one month of follow-up 11. Thirty-one trials were retained, evaluating sixteen interventions against placebo, with samples ranging from 5 to 117 participants. Propranolol, primidone, topiramate and botulinum toxin A did show an improvement in tremor severity in more than one trial. But applying a modified GRADE framework leads the authors to a severe conclusion: the evidence is insufficient to support with confidence the efficacy of any of the available drug treatments, the limitations lying in risk of bias and imprecision.
That conclusion does not mean these treatments do not work. It means the quality of the trials does not allow it to be stated with the solidity one would like. It is a nuance that matters when a patient asks whether “it is worth a try”: the honest answer is that propranolol and primidone remain the first reasonable options, while knowing that their effect is variable and imperfectly established.
A Bayesian network meta-analysis of 33 trials and 1,251 patients reaches the same tempered view 10. Deep brain stimulation obtains the greatest relative efficacy there and first place in the ranking, ahead of thalamotomy and several beta-blockers including propranolol. The authors immediately add that the GRADE level of evidence for these conclusions is “low” or “very low”, and that the results must therefore be applied with caution.
The interventional treatments
For severe tremors resistant to drugs, two routes exist: deep brain stimulation, and MRI-guided focused ultrasound thalamotomy, a technique without opening the skull whose use has grown in movement disorders 12. These indications belong to specialist centres.
One point is of direct interest to rehabilitation: thalamic stimulation modulates gait ataxia in essential tremor, and not always in the right direction depending on the settings used 20. A stimulated patient who describes their balance getting worse is not imagining it, and the information deserves to reach the team that adjusts the device.
What can rehabilitation do, honestly?
Little for the tremor itself, more for what surrounds it. Saying so frankly is better than leaving it hoped for.
Let us start with the finding that structures this chapter: no evidence-based review of the treatment of essential tremor retains any physiotherapy intervention, neither the 2019 one 9, nor its 2026 update 11. There is nothing for essential tremor resembling what the exercise literature has built in Parkinson's disease, where a network meta-analysis has been able to compare modalities against each other across 156 trials 30.
That does not mean there is nothing to be done. It means an accurate aim has to be stated, and a reduction in tremor that will not be produced must not be sold.
What has evidence, even modest
Strength training. A systematic review of 14 studies, six of them randomised trials, examined the effect of strength training on upper limb postural tremor, force steadiness and dexterity in older people 13. The eight studies in healthy older subjects all report a reduction in postural tremor, an improvement in force steadiness, or both. Among the seven studies in subjects with a condition, significant benefits were seen specifically in essential tremor, whereas little or no change appeared in osteoarthritis or after a stroke.
A more recent preliminary randomised trial compared home-based strength training, aquatic strength training and a control group in older people with essential tremor 14. The sample sizes have to be given so that its weight is clear: twenty-seven participants in all, nine per group, over eighteen sessions. It is a preliminary trial, and it must be read as such.
Cooling the limb. A single-blind randomised crossover study compared, in 20 patients with essential tremor and 20 parkinsonian patients, hand function after immersion in cold water and after immersion in warm water 15. In the patients with essential tremor, the scores for the Archimedes spiral, simulated feeding and draughts were significantly better after cold water than after warm water, and better than at baseline. The effect is transient, but it is measured, and it provides a one-off strategy usable before a specific task.
Tremor-suppression orthoses. A systematic review analysed 46 articles describing 21 upper limb tremor-suppression orthoses 16. Their suppression efficiencies range from 30 - 98 %, which sounds considerable. The authors' conclusion is less so: most of these devices are bulky and heavy, with a poorly adapted human-machine interface, which leads to their rejection by the user. The principle works, the object is not yet wearable day to day 17.
Strength training
of the upper limb
What supports it. A systematic review of 14 studies reporting a reduction in postural tremor and an improvement in dexterity in older people, with significant benefits noted in essential tremor 13.
Its limit. Few randomised trials, small samples, and a population often made up of general older subjects rather than patients. The most recent dedicated trial has nine participants per group 14.
Cooling
before a task
What supports it. A single-blind randomised crossover study, with significant improvement in the Archimedes spiral, simulated feeding and dexterity after immersion in cold water in 20 patients 15.
Its limit. A transient effect, a small sample, an old study not replicated at scale. It is a one-off strategy, not a treatment.
Balance and gait
work
What justifies it. Balance disturbance is seven times more frequent than in controls, independent of age, and associated with near-falls 18. The review of the non-motor burden notes an increased risk of falls 6.
Its limit. The reasoning is indirect: no trial has tested a balance programme specifically in these patients. We apply what we know about fall prevention in older people to a population we have established to be at risk.
Suppression
orthoses
What we know. Mechanical suppression efficiencies of 30 to 98 % across 21 devices analysed 16.
Why not to celebrate too quickly. These devices are described as bulky, heavy and poorly accepted, to the point of being abandoned by users. Worth watching, but nothing to offer today in everyday practice.
Key point
What physiotherapy can promise in essential tremor comes down to three lines. On the tremor itself, little: upper limb strength training may help modestly, with a low level of evidence. On function, more: adapting tasks, equipment and the environment genuinely changes daily life. On balance and falls, there is a real documented need, and that is probably where the benefit is greatest, even though direct evidence is lacking. Saying this clearly at the first appointment avoids disappointment at the sixth session.
Which practical adaptations for eating, drinking and writing?
This is the ground where results are immediate, and it rests on simple mechanical principles.
None of these adaptations is the subject of a randomised trial in essential tremor: that has to be said, and it also has to be said that they follow from well-established properties of action tremor, namely that it grows with distance from the point of support, that it varies with the task 29, and that it is all the more troublesome when the movement demands terminal precision.
The principles behind the advice
- Shorten the lever arm. An elbow resting on the table, a wrist propped against the edge of the worktop, a forearm braced against the trunk mechanically reduce the visible amplitude of the terminal movement. It is the most cost-effective advice and the easiest to put in place.
- Reduce the unsupported travel. Bring the cup towards you rather than reaching the hand out from a distance; put the glass down before letting go rather than handing it over at arm's length.
- Lower the demand for terminal precision. A wide, heavy glass, half filled, with a straw, turns a high-precision movement into a forgiving one. A cup with a lid solves the problem of coffee in public.
- Increase control through weight and diameter. Weighted cutlery with thick handles is held better. The same principle applies to large-diameter pens.
- Choose the moment. Tremor worsens with fatigue, stress, caffeine and being watched. Planning demanding tasks for favourable moments is a legitimate strategy.
- Use cold before a one-off task. The transient improvement after cooling the limb is documented 15 and can be used before a signature or an important meal.
The trap of the forgotten non-dominant arm
Adaptations are naturally designed for the hand that writes. Yet tremor of the non-dominant arm contributes independently to reported disability and to measured dysfunction 7, because most everyday actions are bimanual: steadying the plate, holding the jar, keeping the sheet of paper still. Assess and adapt both sides.
For handwriting
Handwriting is often the complaint that prompts the consultation, because it is public. Three levers combine: a large-diameter, slightly weighted pen, firm support of the forearm and wrist on the table, and accepting larger handwriting. Deliberately enlarging the letters lowers the precision demand per unit of stroke. It is the exact opposite of the advice given in Parkinson's disease, where the aim is to counter letters getting smaller 28, which nicely illustrates that the two tremors are not rehabilitated in the same way.
The administrative workarounds also have to be named, because they bring great relief: electronic signatures, online transfers, digital forms. A patient who dreads signing in front of a bank clerk will get more benefit there than from ten sessions of fine motor work.
How do you apply this in practice?
An assessment that takes ten minutes, and a plan of care stated without excessive promises.
The minimum assessment
- The three positions. Hands resting and relaxed, arms held out, finger-to-nose and hand towards a glass. Note in which one the tremor appears: that is the heart of the sorting.
- The search for associated signs. Twenty hand opening-and-closing movements to look for decrement, passive tone, facial expression, arm swing when walking. Their presence takes it outside the frame.
- A handwriting sample and an Archimedes spiral, wrist unsupported, on both sides.
- Tandem gait. Count the missteps over ten steps: it is the most cost-effective measurement in this assessment, given how frequent balance disturbance is in this population 18.
- What has been given up. What the patient has stopped doing, and what they would like to be able to do again. That is what will set the goals.
What you tell the patient
An honest plan of care comes down to three ranked aims, and they are better stated from the outset:
| Aim | What you do | What you can promise |
|---|---|---|
| Making balance safe | Falls assessment, dynamic balance and gait work, home adaptation | Benefit expected by analogy with fall prevention in older people, on a risk documented in this population. No dedicated trial. |
| Getting tasks back | Adapting equipment, supports, workaround strategies, reorganising activities | An immediate and often substantial effect on the tasks targeted, without acting on the tremor itself. |
| Acting on the tremor | Upper limb strength training, one-off cooling before a task | A modest effect with low-level evidence for strength training, transient for cold. To be offered without overselling it. |

Three frequent mistakes
- Treating essential tremor like Parkinson's. Rhythmic cues, amplitude training and attentional strategies were built for a disorder of movement automaticity. Essential tremor is not that disorder, and nothing allows those protocols to be transposed.
- Promising a reduction in tremor. No evidence-based review retains any physiotherapy intervention for that aim. Promising that result invites a disappointment that discredits the rest of the work, including the part that does work.
- Neglecting the psychosocial impact. Embarrassment, avoidance of social situations and mood are part of the documented picture 6. A patient who no longer dares have lunch with their colleagues has a problem that is not measured in hertz.
In essential tremor, physiotherapy does not make the tremor smaller. It makes it possible to drink again, to walk without fear, and to go out. That is a more modest aim to state, and often a more important one for the patient.
Frequently asked questions
Is essential tremor the start of Parkinson's disease?
No, they are two distinct conditions, and the great majority of patients with essential tremor will not go on to develop Parkinson's disease. The two can nevertheless coexist, and the international classification recognises intermediate pictures 1, described in specialist clinic series 21. The appearance of a rest tremor, of a slowness that fades away or of marked asymmetry warrants a further opinion.
Why does my tremor stop when I put my hands down?
Because that is precisely its nature. Essential tremor is an action tremor: it shows itself when a posture is held and on directed movement, and not at complete rest 1. That is also what makes it more disabling day to day than parkinsonian tremor, which does the opposite: patients with essential tremor report a median of ten waking hours with tremor a day, against three hours in Parkinson's disease 4.
Is it true that a glass of wine makes the tremor disappear?
An objective response to alcohol was measured in 80 % of patients in a standardised challenge study, with an effect correlated to blood alcohol level and not to sedation 8. Two caveats are needed nonetheless. First, what the patient perceives of that response matches poorly what is measured. Second, that does not make alcohol a treatment: the effect is brief, followed by a rebound, and the risk of misuse is real in patients who find their tremor hard to live with in company.
Can physiotherapy reduce my tremor?
Little, and that has to be said. No evidence-based review of essential tremor retains any physiotherapy intervention 9 11. Upper limb strength training has shown a reduction in postural tremor and an improvement in dexterity, with a low level of evidence 13. Rehabilitation does, on the other hand, genuinely act on function, through adapting tasks, and on balance, whose impairment is documented in this population 18.
Should balance be worked on in a patient whose hands tremor?
Yes, and it is probably the most useful contribution. The prevalence of missteps on tandem gait is seven times that of controls, gait is slower and more asymmetrical, and these impairments translate into near-falls 18. The review of the non-motor burden confirms an increased risk of falls 6. No trial has tested a specific programme in this population: the reasoning is indirect, and it is worth explaining to the patient.
Are weighted objects and orthoses of any use?
Weighted cutlery and pens follow a simple mechanical principle and help many patients, without having been the subject of dedicated trials in essential tremor. Active suppression orthoses have been studied: their mechanical efficiencies run from 30 to 98 %, but the systematic review concludes that they are too bulky and heavy, with a poorly adapted interface that leads users to abandon them 16.
Does cold really improve movement?
A single-blind randomised crossover study compared immersion in cold and in warm water in 20 patients with essential tremor: the Archimedes spiral, simulated feeding and dexterity were significantly better after cold water 15. The effect is transient. It is a one-off strategy, before a specific task, and not a long-term treatment.
My doctor has prescribed propranolol, does it work?
It is one of the two first-line options, along with primidone, and the 2019 review rated them clinically useful 9. The 2026 update, stricter on methodology, nevertheless concludes that the available evidence remains insufficient to state with confidence the efficacy of any of the drug treatments 11. In other words: it is worth a try, the effect varies from one patient to another, and the decision belongs to the prescriber.
My tremor affects my head and voice too, is it the same problem?
Midline tremors (head, voice, trunk) are part of the spectrum of essential tremor, and they carry a particular significance: they are associated with poorer tandem gait performance 19. On the treatment side, the MDS review stressed that the evidence remains insufficient for voice and head tremor, whereas it exists for the limbs 9. A head tremor with a torsional attitude should raise the possibility of a dystonic component.
Is my tremor going to get worse?
It generally worsens slowly over time, and a longitudinal study has followed the clinical and neurophysiological course in these patients 24. The prevalence of the condition itself rises by 74 % per decade of age 2. That does not imply an inevitable loss of independence: it is the adaptation of everyday tasks and the safety of walking that determine the real impact, far more than the measured amplitude of the tremor.
