I like that this was on chronic. How can your doctor and therapist recreate this rehab for you? I bet it would work even better if applied during the acute phase.
Abstract
Conventional
therapies do not provide paralyzed patients with closed-loop
sensorimotor integration for motor rehabilitation. This work presents
the recoveriX system, a hardware and software platform that combines a
motor imagery (MI)-based brain-computer interface (BCI), functional
electrical stimulation (FES), and visual feedback technologies for a
complete sensorimotor closed-loop therapy system for poststroke
rehabilitation. The proposed system was tested on two chronic stroke
patients in a clinical environment. The patients were instructed to
imagine the movement of either the left or right hand in random order.
During these two MI tasks, two types of feedback were provided: a bar
extending to the left or right side of a monitor as visual feedback and
passive hand opening stimulated from FES as proprioceptive feedback.
Both types of feedback relied on the BCI classification result achieved
using common spatial patterns and a linear discriminant analysis
classifier. After 10 sessions of recoveriX training, one patient
partially regained control of wrist extension in her paretic wrist and
the other patient increased the range of middle finger movement by 1 cm.
A controlled group study is planned with a new version of the recoveriX
system, which will have several improvements.
