Objective To investigate the effect of rotational training on spasm after spinal cord injury. Methods From July, 2010 to July, 2015, 38 patients with spinal cord injury were randomly divided into treatment group (n=19) and control group (n=19). Both groups accepted routine physical therapy, and the treatment group accetpted rotation training in addition. They were assessed with modified Ashworth Scale, adductor angle, hip flexion, and modified Barthel Index before and 6 weeks after treatment. Results Both groups improved in modified Ashworth Scale (Z>-2.286, P<0.05), adductor angle (t>5.6121, P<0.001), angle of hip flexion (t>5.1677, P<0.001) and modified Barthel Index (t>-6.7428, P<0.001) after treatment, and improved more in the treatment group than in the control group (P<0.05). Conclusion Rotation training may relieve spasm after spinal cord injury, and improve the range of motion and activities of daily living.
