Useless for us until we get a protocol. Do you expect us to figure this out on our own? You are being paid for stroke rehab. DO YOUR FUCKING JOB!
Mirror therapy for stroke rehabilitation: Tricking the brain into believing what it sees
The Bottom Line
- Eighty percent of people have difficulty moving their arms or legs after a stroke.
- Mirror therapy uses a mirror to create the illusion that the arm or leg affected by the stroke is moving.
- After a stroke, mirror therapy can improve movement in affected upper or lower limbs and activities of daily living, and appears useful as a supplement to other stroke rehabilitation activities.
Immediately after a stroke, about
80% of people have difficulty moving their arms or legs (1;2). Although
these changes may not be permanent—with some people regaining partial
or full limb function (1;3;4;5)—the road to recovery can be long. But
did you know that it is possible to trick the brain into believing what
it sees? Mirror therapy is being used more and more in stroke
rehabilitation to dupe the brain and restore limb function (1).
Stroke affects up to 10% of older adults in Canada (6), making it the third leading cause of death nationally (7), and one of the leading causes of disability worldwide (1;8). Stroke occurs when the blood supply to the brain is interrupted or reduced, causing brain cells to die (9). This can cause a variety of temporary or permanent disabilities, including paralysis (1;3), pain (1;10) or difficulty completing daily activities such as walking, eating, or getting dressed (1).
Mirror therapy may be one way to help stroke survivors recover movement in their arms and legs (1). During mirror therapy, a mirror is used to create a reflection of an unaffected arm or leg in place of the affected limb (1;11). When the unaffected limb is moved, the mirror image “tricks” the brain into thinking that the affected limb is moving (1;12). Although it is unclear exactly how this process works (1), it’s been suggested that this illusion causes changes in the brain that help the person recover their mobility (1;13). Even better, mirror therapy is relatively easy to do, and has the potential to be completed at home by the individual themselves (1).
But does this approach really work, or is it all smoke and mirrors?
This review found that mirror therapy can be safe and effective. In fact, it improved upper and lower limb movement in affected limbs and the ability to conduct daily activities for up to and potentially beyond 6 months after stroke, with no side effects reported. While there was also some evidence that mirror therapy may reduce pain, definitive conclusions could not be made based on the studies included in the review. It’s also important to keep in mind that it’s not yet clear if mirror therapy can replace other types of stroke therapy—since more research is needed comparing mirror therapy used on its own to other strategies.
Overall, there is cause for optimism, as mirror therapy appears to be a good strategy that can be added to other stroke rehabilitation approaches (1).

What the research tells us
A recent systematic review showed that mirror therapy is a promising approach to stroke rehabilitation. Mirror therapy was studied in the time shortly after stroke and up to 6 months later, for both arm and leg rehabilitation. It was delivered in hospitals, as part of inpatient and outpatient rehabilitation, and at home. Most studies included in the review used a mirror box to deliver the therapy, although two studies used virtual reflection on a screen. In some cases, mirror therapy was combined with other strategies such as electrical stimulation. Mirror therapy was carried out 3-7 times a week for 2-8 weeks, and for 15-60 minutes at a time.This review found that mirror therapy can be safe and effective.
