mental practice

Athletes have long known a curious thing: vividly rehearsing a movement in your imagination — picturing yourself sinking the putt, feeling the swing — can actually improve the real performance later, without lifting a finger. Mental practice brings that same trick into rehabilitation, asking patients to repeatedly imagine performing a movement they are trying to relearn.

The technique is motor imagery: the person, usually relaxed and guided by a recording or therapist, vividly rehearses a specific action in the first person — imagining reaching for the cup, feeling the fingers close around it — without any actual movement. This is not idle daydreaming. Brain imaging shows that imagining a movement activates many of the same motor and planning regions that the real movement would, so mental practice gives those circuits a workout and extra repetitions even when the body cannot yet perform, or is too tired or weak to keep practising physically. It is typically combined with real practice, not used instead of it.

In rehabilitation, mental practice is a low-cost, low-risk supplement studied mainly for upper-limb recovery after stroke. It is appealing precisely because it adds repetitions without physical fatigue and can be done by people too weak to move much. The honest picture: the evidence suggests a modest benefit when added to conventional therapy, not a substitute for real movement, and it depends on the person being able to generate clear motor imagery — something stroke or brain injury can itself impair.
