Study conducted to determine the influence of spinal cord injury level on shoulder muscle function during wheelchair propulsion. A sample of 69 men who used wheelchairs participated in the study. The participants were placed in four groups based on level of spinal cord injury (SCI). Shoulder muscle activity was documented during propulsion with bipolar, fine-wire electrodes inserted into anterior, middle, and posterior portions of the deltoid, the sternal portion of the pectoralis major, lower serratus anterior middle trapezius, spraspinatus, infraspinatus, subscapularis, and long heads of the biceps brachii and triceps brachii. A rigid-frame, lightweight wheelchair was used for the propulsion trials. The researchers found that level of SCI significantly affected the shoulder muscle recruitment patterns during wheelchair propulsion.
