Description
Summary:Study design: A cross-sectional study design. Objectives: To characterize and specifically quantify impairments in muscle function after chronic incomplete spinal cord injury (SCI). Setting: University of Florida, Gainesville, FL, USA. Methods: Voluntary and electrically elicited contractile measurements were performed and voluntary activation deficits were quantitatively determined in the knee extensor and ankle plantar flexor muscle groups in 10 individuals with chronic incomplete SCI (C5-T8, ASIA C or D) and age-, gender-, height- and body weight matched healthy controls. Results: Persons with incomplete-SCI were able to produce only 36 and 24% of the knee extensor torque and 38 and 26% of the plantar flexor torque generated by noninjured controls in the self-reported less-involved and more-involved limbs, respectively ( P
