Preliminary investigation of an electromyography-controlled video game as a home program for persons in the chronic phase of stroke recovery.

Objective: To investigate the preliminary effectiveness of surface electromyography (sEMG) biofeedback delivered via interaction with a commercial computer game to improve motor control in chronic stroke survivors.

Design: Single-blinded, 1-group, repeated-measures design: A1, A2, B, A3 (A, assessment; B, intervention).

Setting: Laboratory and participants' homes.

Cervical intraspinal microstimulation evokes robust forelimb movements before and after injury.

Objective: Intraspinal microstimulation (ISMS) is a promising method for reanimating paralyzed limbs following neurological injury. ISMS within the cervical and lumbar spinal cord is capable of evoking a variety of highly-functional movements prior to injury, but the ability of ISMS to evoke forelimb movements after cervical spinal cord injury is unknown. Here we examine the forelimb movements and muscles activated by cervical ISMS both before and after contusion injury.
