Why does the hand take longest after a stroke?
The hand takes longest because fine finger movements need more control than large movements from the shoulder and elbow. Most of the recovery happens in the first eight to twelve weeks, after which the curve flattens. Strength alone is not enough: gripping and letting go need the right timing and reliable sensation, and both have to be practised.
A stroke does not damage the arm, it damages the control of the arm. Lifting the shoulder needs coarse activation of whole muscle groups. Opening the hand around a cup needs the right moment, the right amount of force and feedback about whether it worked. Because the hand needs more control than the shoulder, it comes back later.
There is a second problem that is often overlooked: letting go is harder than gripping. The flexor muscles of the fingers are stronger and become active again earlier than the extensors. So you often see a hand that closes around an object but no longer opens.
- Favourable signs in the first week are active extension of the wrist or fingers and active abduction of the shoulder.
- Unfavourable signs are disturbed deep sensation, meaning no sense of where the arm is, and neglect of the more affected side.
- If active finger extension is absent in the first week, the outlook for good hand function is markedly poorer. That does not mean nothing is possible, but the way is longer.
Judging the course of recovery is always your doctor’s task, never the therapy’s. How occupational therapy works from there is described under neurology.
What does learned non-use mean?
Learned non-use means the more affected hand is not used although more would be possible. In the first weeks almost every attempt fails, the less affected hand takes over, and the brain remembers that success. The non-use is practised like a habit and persists even when strength returns.
This is exactly where occupational therapy starts. With you, it picks out the everyday actions in which the more affected hand can realistically take part, breaks them into intermediate steps, adapts objects and surroundings so the attempt succeeds, and raises the demand only once it succeeds reliably.
The term comes from basic research. Animals whose forelimb stopped working after a nerve injury went on not using it even once they could have. In people there is the added fact that the other hand can take over any task at once.
In practice it looks like this: the bread is buttered with one hand, the zip is held with the teeth. Each of these solutions works, and each of them means the more affected hand does less.
How to recognise learned non-use
- A movement succeeds in therapy and never in daily life.
- The hand lies beside the plate at meals and while dressing although it could hold something.
- Family members automatically pass objects to the less affected side.
The difference sets the direction of treatment. Where there is no activation at all, the work is about protecting the shoulder and about methods such as mirror therapy. Where movement exists but stays unused, the work is about opportunities in daily life, and those arise mainly at home.
What does task-oriented practice with many repetitions achieve?
Task-oriented practice means repeating real actions instead of moving muscles one by one, such as lifting a cup or closing a zip. Sensorimotor learning, the learning of movement through sensation and feedback, needs many repetitions at your own limit. The transfer into daily life does not happen by itself; it has to be planned and practised.
The brain learns a movement by carrying it out often enough and finding out whether it worked. An everyday action contains both: the cup stands or it tips. Simply moving the arm through its range does not supply that feedback, which is why it is of little use as training.
The number of repetitions needed is higher than one therapy session a week can deliver. That makes practice at home the larger part of the treatment. For the later phase the guidelines recommend several hours of structured training a week, spread over several days.
Why everyday activities make the best exercises
- They make sense. The laundry basket has to be emptied anyway. That carries motivation further than a pegboard.
- They are embedded. Holding the toothpaste with the more affected hand means practising twice a day without an extra appointment.
- They can be graded. Holding a jar first and opening it later raises the demand so that it just about succeeds rather than being effortless.
Movements that do not succeed at all yet need a different approach. Mirror therapy, about half an hour daily over several weeks, is well studied for this. Templates for use at home are available under information sheets for patients.
Who is constraint-induced movement therapy suitable for?
In constraint-induced movement therapy the less affected hand is put out of action for hours at a time so that the affected one has to work. It suits people who still have some residual movement: as a guide, about twenty degrees of active wrist extension and ten degrees of active finger extension. Without that residual movement the method is unsuitable.
The method is the direct answer to learned non-use. It has three parts: the less affected hand is restricted with a mitt, the more affected one practises tasks of gradually rising difficulty, and it is agreed in writing which activities at home fall to it.
Where someone is coming from matters here. Inpatient rehabilitation provides very intensive therapy over several weeks; anyone moving from there into outpatient occupational therapy starts from a quite different point and with far fewer appointments a week. What makes sense in an outpatient setting therefore follows less from the original study protocol than from what can actually be practised at home.
- The original form calls for around six hours of practice a day and restriction of the less affected hand during about ninety per cent of waking hours, over two weeks.
- The modified form works with far less practice time a day and a shorter daily restriction, but over several weeks; the protocols differ from study to study. This is the version that is feasible on an outpatient basis.
- It is not suitable where there is no residual movement, where there is a risk of falling, and where restricting the less affected hand would endanger safety at home.
Restricting the less affected hand is the conspicuous part, but not the effective one. The difference is made by the written agreement for home, which says which action is carried out how often with the more affected hand and who does the reminding.
What is spasticity, and why does stretching not resolve it?
Spasticity is a speed-dependent rise in muscle tone: the faster you move the arm, the harder it holds against you. It arises in the brain, not in the muscle. Stretching makes the muscle softer for a while and helps prevent shortening, but it does not resolve the spasticity itself.
About a fifth to a quarter of those affected show raised muscle tone within the first two weeks. A year later the proportion lies between a fifth and a third, depending on the study. Spasticity is therefore common, but it does not affect the majority.
The expectation that daily stretching keeps the arm loose is widespread, and the evidence for it is thinner than that spread suggests. A large review of stretching for contractures found no clinically meaningful benefit for joint mobility. Night splints do not reliably prevent a flexed posture either.
- What stretching does: it keeps the muscle more yielding for a limited time and makes washing and dressing easier.
- What stretching does not do: it does not lower spasticity lastingly and does not replace a programme of practice.
- What works: active practice with a purpose. Contrary to an old assumption, strength training does not increase spasticity.
- What your doctor can offer: botulinum toxin into individual muscles. It lowers tone for some months and opens a window in which practice goes better.
- What you can watch for: cold, pain, fear and a full bladder raise tone. Removing a trigger of that kind often achieves more than half an hour of stretching.
How does a painful shoulder arise, and how is the arm positioned?
The paralysed shoulder is no longer held by its muscles, the head of the upper arm sinks, and tendons and capsule are overstretched. Pain usually appears in the first months. What matters is how the arm is handled and positioned; pulling on it firmly does harm.
Depending on the definition it affects between one sixth and two thirds of those concerned. Painful shoulders regularly show a subluxation, meaning the head of the upper arm sinks out of the socket, together with irritation of the joint capsule and damage to the tendons around the joint.
The most important finding for daily life: training for staff, for the person affected and for family members in how the arm is to be handled markedly reduces shoulder and hand complaints.
- Never pull on the affected arm when transferring or standing up. Guide at the trunk or at the pelvis.
- When sitting, rest the arm on a cushion or on the table, because an arm hanging free pulls at the shoulder.
- When lying down, support the arm with a cushion so that the shoulder is propped forwards.
- Passive lifting or abduction beyond ninety degrees belongs in trained hands, not in daily life.
- When dressing, the more affected arm goes into the sleeve first; when undressing, the less affected one comes out first.
What can families do at home, and what is better left alone?
Families decide, in part, how much the more affected hand gets to do. What helps is allowing time, preparing tasks so the hand can join in, and never pulling the arm by the wrist. Taking everything over is well meant and practises the non-use along with it.
The commonest question from families is whether they are helping too much. Usually yes, and that is understandable, because doing it yourself is quicker and the drawback only shows after weeks.
What is better left alone
- Do not pull on the affected arm; when standing up and transferring, guide at the trunk or the pelvis.
- Do not take everything over. Every action you take on is one repetition fewer.
- Do not stretch against resistance when the arm holds against you or when it hurts.
- Do not keep the hand out of daily life because it is slow.
How long is recovery still possible after a stroke?
Most of the recovery happens in the first weeks and months, yet improvements are documented even after a year when practice is targeted. Nothing is guaranteed, and how far it goes cannot be said at the start. Because the question stays open, carrying on practising is worthwhile even after months.
Both sentences have to stand side by side. Anyone told after eight months that nothing more can be done is hearing something that is not true in that form: studies of intensive arm treatment in the chronic phase still show improvements then. Anyone told the opposite, that with enough practice the hand will certainly come back, is hearing a promise nobody can give.
What changes is the kind of progress. Early on it is about activation returning, later about how many of the day’s actions the more affected hand takes on. The second part can be improved even when strength stays the same.
- Set goals as actions, not as degrees: doing up the jacket, holding the carrot while cutting.
- Document the treatment over a longer period as precisely as you can. Functional progress only becomes clearly visible after some time with persistent training and a great deal of practice.
Treatment in the practice or at home needs a doctor’s prescription. It is billed to the insurer responsible; what is left with you through the deductible (Franchise) and the retention fee (Selbstbehalt) is something your health insurer will tell you.
