Changes in motoneuron excitability in hemiplegic subjects after passive exercise when using a robotic arm.

Objective: To test the hypothesis that motoneuron excitability in stroke subjects is influenced by peripheral sensory input through passive exercise to the hemiplegic upper extremity.

Design: Case-control prospective study.

Setting: Physical medicine and rehabilitation inpatient and outpatient clinic at a tertiary Veterans Affairs medical center.
