Motion sensor technology could help stroke victims

A team of researchers are hoping that motion sensors similar to those developed for games consoles, such as the Nintendo Wii could help rehabilitate stroke patients.

Scientists at the Oxford University are looking at this technology to see if it can be used to improve upper body movements during physiotherapy.

The trial, which is still being planned, uses 12 infra-red cameras, which work together to track the movement of reflective markers stuck to a person's wrist, arm and torso in real time.

These will also help the researchers look at people before and after the exercises and how much they use particular joints.

It is also hoped that the technology, which uses the same sensing technology that records the movements of actors for computer-generated films, will allow patients to see their progress and motivate them to keep exercising.

Eventually the researchers want to develop a version of the technology allowing the stroke patient to use it at home and be monitored by the therapist or GP remotely.

Physiotherapists should also be able to assess the range of movement a patient has and help them tailor exercises accordingly.

Research leader Dr Penny Probert Smith said: "We hope to break down useful movements - anything from handling money to tying shoelaces - into different elements that can be quantified and then assessed against standardised measures based on current clinical tests."

The research has also been welcomed by the Stroke Association.

Andrea Lane, a representative for the charity said: "Stroke is the leading cause of severe disability in the UK and rehabilitation plays a vital role in recovery following a stroke.

"New technology is increasingly offering alternative methods to traditional exercise and we look forward to seeing what the results of the study show."
