Arm and Hand Recovery After Stroke

Why the arm often trails behind the leg

Families often notice the leg comes back first. The person is standing, maybe taking a few steps, while the arm still hangs at their side. Part of the reason is anatomy: the most common stroke territory hits the area controlling the face and arm harder than the leg. Part of it is use. Walking forces the leg to work many times a day, while the other hand quietly takes over every job the weak arm used to do.

Hand skill also demands finer control. Taking weight through a leg needs a few large muscles to switch on at the right moment. Buttoning a shirt needs dozens of small ones working together, plus sensation telling you where the button is. So slower arm recovery after stroke is normal, and on its own it doesn't mean the arm won't improve.

Protecting the shoulder in the floppy stage

In the first weeks the weak arm is often flaccid: floppy, with little or no muscle tone. The shoulder is a shallow joint that relies on muscles to hold the ball in its socket. With those muscles switched off, the weight of the arm slowly drags the joint downward. That's subluxation, and you can sometimes feel a gap about a finger wide just below the bony point of the shoulder.

A subluxed shoulder isn't always painful, but it's easily hurt. These habits protect it:

• Support the arm whenever the person sits, on a pillow on the lap, an armrest or a table in front. Never let it dangle over the side of the chair.
• Never lift or pull the person by the weak arm or under that armpit. Transfers go through the trunk and hips.
• When they lie on the weak side, ease the shoulder blade forward so they aren't lying on the point of the shoulder.
• Skip overhead pulleys and vigorous arm swinging, which strain the loose joint.
• Handle the arm at the shoulder and elbow together, not by the wrist.

Slings are debated. A sling can support the arm while standing or walking early on, but worn all day it holds the arm bent and still, which invites stiffness. Your physiotherapist will say whether one is needed and for how long. Lying and sitting positions are covered in detail in our guide to positioning in bed.

Shoulder pain and what helps

Shoulder pain is one of the commonest reasons arm therapy stalls. The causes vary: rough handling during transfers, subluxation, tight muscles pulling across the front of the chest, a joint stiffened from lying still, or irritated rotator cuff tendons. Occasionally the whole hand also turns swollen, shiny and very sensitive to touch, which can be a complex pain condition. That needs the doctor to see it promptly.

Pain changes behaviour. The person guards the arm, won't let anyone move it, and the shoulder stiffens further. So we deal with pain early: careful positioning, gentle movement within comfort, sometimes TENS from the home kit for short-term relief, and teaching every family member the same safe way to handle the arm. Pain medicines are the doctor's decision.

Learned non-use: when the good hand is the problem

Here's a pattern we see in nearly every home. Early on, the weak hand can't do anything, so the other hand does it all and the family helps with the rest. Weeks later some movement has come back, but by now the brain has learned that the strong hand handles everything. The weak arm still isn't used, even for things it could manage. This is called learned non-use.

The brain rewires around whatever is practised (our piece on neuroplasticity explains how). An arm that is never asked to work doesn't get the practice it needs. So we hunt for every small job the weak hand can join in: holding the plate steady while the other hand eats, pressing the light switch, pushing a sleeve up, holding the toothpaste tube.

Task practice, and plenty of it

Movement returns through repetition, and the amount needed is far more than most people expect. A few sets during a 45 to 60 minute session won't do it alone. What happens between sessions matters more.

Practice works best when it's tied to a real task with a clear goal. Sliding a towel across the table in circles. Pushing a steel glass forward and drawing it back. Picking up clothes pegs and dropping them in a box. Turning the pages of a magazine. Kneading soft dough. Each is graded to the person's level. If they can only shrug the shoulder, we start there. If the fingers have begun to open, we work on letting go of objects, which is usually harder than gripping them.

A muscle stimulator from our home kit can help wake up weak wrist and finger muscles during task practice when the person can't yet start the movement alone. It assists practice; it doesn't replace it. For ideas, see the elbow, wrist and hand exercises, and for the earliest stage, passive and assisted range of motion. The selection and dose come from your physiotherapist after assessment.

Constraint-style therapy: who it suits

Constraint-induced movement therapy turns learned non-use on its head. The stronger hand is restricted, usually with a padded mitt, for large parts of the day so the weak hand has to do the work, combined with intensive task practice. For the right person it's one of the better-supported arm approaches.

It suits a minority. The person needs some active wrist lift and some finger opening, decent balance (the protective hand isn't free if they stumble), good understanding, and the patience for hours of frustrating effort. It isn't for a flaccid arm, someone at high fall risk, or a person with significant memory problems. Modified versions use shorter blocks, an hour or two during supervised tasks. We assess first, and we don't recommend running it unsupervised.

Splints, tightness and spasticity

As tone returns, many people develop spasticity: the elbow bends, the wrist curls down and the fingers clench into a fist. Left alone, the muscles shorten and the palm becomes hard to open, clean and dry, and the skin inside it starts to break down.

A resting hand splint, usually worn at night, holds the wrist and fingers in a stretched position. It must fit properly, because a badly fitted splint causes pressure sores, especially where sensation is poor. Daily stretching and positioning work alongside it. Where spasticity limits function or causes pain, the neurologist or rehabilitation doctor may discuss medical options, and physiotherapy afterward makes the most of any window they open. Splints and grip aids are covered in our guide to stroke recovery equipment.

When the hand can't feel

Sensation problems are easy to overlook because they don't show. A hand that moves but can't feel drops things the moment the eyes look away, and it's at real risk near a hot tawa, a pressure cooker or a cup of chai. Check the hand daily for cuts, burns and pressure marks, and test bath water with the other hand. Sensory retraining, picking out textures and objects with the eyes closed, is part of hand therapy. Our guide to numbness and tingling after stroke goes further.

Realistic goals for the hand

Not every hand gets back to writing and buttoning, and it's fairer to say so early. But a hand that can't do fine work can still be a useful helper: holding a bag, steadying a bottle while the other hand opens it, pinning paper flat to write, carrying a light plate. That changes daily life a lot. We set goals in small steps and measure them, and the stroke progress calculator is a simple way to track change.

If progress seems to stop, read about what a recovery plateau really means before deciding it's over. For hands-on help, our physiotherapy for stroke paralysis works on the arm in detail, and the wider recovery picture is in the main stroke recovery guide.
