Brain Computer Interface - Functional Electrical Stimulation (BCI-FES) Therapy for Stroke Rehabilitation
In Brief
A clinical study evaluating BCI-FES dorsiflexion therapy, Physiotherapy one hour, and 1 other intervention for Ischemic Stroke and Hemorrhagic Stroke. Completed, enrolled 62 participants across 1 site.
Detailed Summary
There are over 7 million stroke survivors in the US alone, with approximately 795,000 new cases annually. Despite the best available physiotherapy, 30-60% of stroke survivors remain affected by difficulty walking, with foot weakness often being the main cause. Given that post-stroke gait impairments remain poorly addressed, new methods that can provide lasting improvements are necessary. Brain-computer interface (BCI) technology may be one such novel approach. BCI technology enables "direct brain control" of external devices such as assistive devices and prostheses by translating brain waves into control signals. When BCI systems are integrated with functional electrical stimulation (FES) systems, they can be used to deliver a novel physical therapy to improve movement after stroke. BCI-FES systems are hypothesized to stimulate recovery after stroke beyond that of conventional physical therapy.

Interventions
BCI technology enables "direct brain control" of external devices such as assistive devices and prostheses by translating brain waves into control signals. When BCI systems are integrated with functional electrical stimulation (FES) systems, they can be used to deliver a novel physical therapy to improve movement after stroke. The automated software will analyze the data to generate and calibrate a BCI decoder. In the online phase, the subjects will perform 20-25 BCI-FES runs. In each run, subjects will follow 10 alternating epochs of 10-s long idling/dorsiflexion textual cues, and respond by either idling or attempting dorsiflexion to elicit BCI-FES mediated contractions of the TA muscle.
This will consist of a standardized regimen of activities typical of conventional post-stroke gait therapy, including passive/active range of motion exercises (to reduce/prevent excessive plantarflexor contractures), lower-extremity muscle strengthening, and a progression from treadmill to overground walking exercises. A total of 12 sessions will be performed at 3x/week.
