Go-Hand detects wrist and arm movements and provide auditory feedback
for wrist movement over a range of starting capacities. The focus is on wrist movement because one of the strongest prognostic indicators for recovery of arm function post-stroke is 20 degrees of active wrist extension.

One of the most frustrating and persistent motor sequelae of stroke is poor arm and hand function. There are many therapies for arm function post-stroke. These are classified as: (i) neuromuscular interventions involving repetitive therapeutic movements, motor learning activities, task-specific practice training and constraint induced movement therapy; (ii) musculoskeletal interventions (strengthening, stretching, spasticity reduction techniques); (iii) functional activities (learning new ways to perform needed activities); and BATRAC (iv) assistive modalities (biofeedback, electromyography triggered neuromuscular electrical stimulation,electrical stimulation, robotics, transcranial magnetic stimulation).1 The most effective strategies use repetitive, meaningful movement to promote neuroplasticity, with the aim of changing the brain, to support long lasting improvements in arm function.
