Abstract:
Study compared shoulder strength and muscle imbalance between subjects with spinal cord injury who were manual wheelchair users and able-bodied control subjects. The impact of age and neurological level of injury (NLI) on weight-normalized strength (WNS) was also examined. Participants completed bilateral shoulder isokinetic strength testing in the sagittal, frontal, and horizontal plane at 60 degrees/second using the BioDex system. WNS was calculated by dividing the peak torque value by the individual's weight. No significant difference was seen in shoulder strength or strength ratios between the SCI group and the control group. However, NLI was significantly related to WNS on several planes in the SCI group. To evaluate the impact of this finding, the SCI group was divided into 2 groups based on a high or a low NLI. The low-SCI group was significantly stronger than the high-SCI group in most planes. The high-SCI group was significantly weaker than the control group in extension and a trend was seen in flexion, abduction, and external rotation. The low-SCI group was significantly stronger in abduction than the controls.
