The research question was whether WBV could evoke lower extremity electromyography (EMG) activity in able-bodied individuals and individuals with SCI, and which vibration parameters produced the largest magnitude of effect: Ten male subjects participated in the study, six able-bodied and four with chronic SCI



WBV elicited lower extremity EMG activity, in able bodied and SCI subjects' resting muscles (majority of SCI subjects had motor complete injuries and an inability to voluntarily contract lower extremity muscles

45 Hz vibration with an amplitude of 1.2 mm was the most reliable combination of WBV parameters to elicit EMG activity, in both AB and chronic SCI subjects

These findings suggest that WBV with appropriate parameters may constitute a promising intervention to treat musculoskeletal degradation after chronic SCI
