Force was measured from triceps brachii motor units in individuals with chronic cervical spinal cord injury (SCI) and in able-bodied (A-B) control subjects using spike-triggered averaging (175 and 48 units, respectively). Eleven percent of units from the SCI population generated normal electromyogra

## Abstract Our first aim was to characterize spontaneous motor unit activity in thenar muscles influenced by chronic cervical spinal cord injury. Thenar surface electromyography (EMG), intramuscular EMG, and abduction and flexion forces were recorded. Subjects were instructed to relax for 2 min. U
The electrical and mechanical properties of paralyzed human thenar muscles were measured in response to supramaximal stimulation of the median nerve in individuals with chronic cervical spinal cord injury. These data were compared to those recorded from control muscles. Spontaneous motor unit activi
