Constraint-induced movement therapy after stroke

After a stroke, people naturally rely on the stronger side. Constraint-induced movement therapy (CIMT) gently blocks that habit so the weaker arm gets the practice it needs to recover.

What it is

In CIMT, the stronger arm is restrained (for example, with a mitt) for part of the day while the person practises tasks with the weaker arm through many repetitions. The principle is simple: the brain rebuilds skills it is repeatedly asked to use ^{[National Institute of Neurological Disorders and Stroke (NINDS) 2023]} .

What the evidence shows

A Cochrane review found that CIMT was associated with improvements in arm motor function and use in daily activities, though the certainty of evidence varied and benefits over the long term were less clear ^{[Corbetta D 2015]} .

What it means for daily practice

• Repetition matters. Frequent, focused practice of the weaker side helps.
• Make it functional. Practise real tasks - reaching, gripping, releasing.
• Do it with guidance. A therapist can tailor and grade the challenge safely.

The core idea

Constraint-induced movement therapy (CIMT) encourages use of a weaker arm by limiting the stronger one:

• The stronger arm is restrained for set periods.
• The weaker arm practises intensively on real tasks.
• This counters “learned non-use” of the affected side.

What research suggests

• It can improve arm function for suitable people.
• High intensity and repetition are central.
• Modified, gentler versions exist for wider use.

Practical notes

• Suitability is assessed individually.
• It is demanding, so support and motivation help.
• Gains should be carried into everyday tasks.

Try it gently here

Reaching, dragging, and steady-hold games offer light, repeatable motor practice. Pair them with a movement step in Practice.
