Objective To investigate the possibility of restoring the adapted spinal circuit following spinal cord injury (SCI) by means of long term CPM of the ankle joint. Design Randomized controlled trial with repeated measures. Setting Research laboratory in general hospital. Participants Individuals with motor complete SCI (n=14) were recruited from a community. Interventions CPM of the ankle joint for 1 hour/day, 5 days/week for 4 weeks. Main Outcome Measures The Modified Ashworth Scale (MAS) scores for evaluation of spasticity and post activation depression (PAD) were documented prior to and following intervention. Results The MAS scores were improved after 4 weeks of CPM intervention, indicating a reduction in spasticity of the ankle joint. The PAD is restored after 4 weeks of training. Conclusions Passive motion of the ankle joint alone is sufficient in reversing the adapted spinal circuit and therefore indicates that spasticity following SCI could possibly be managed by CPM intervention. The results of this study support the utilization of passive mode of robot-assisted therapy for human with complete SCI who cannot exercise actively.
