FES-supported interval training following sensorimotor-complete spinal cord injury: a case series

We report on a case-series of four male patients, aimed at investigating the effect of interval training by means of Functional Electrical Stimulation (FES) on ambulation ability in spinal cord injury (SCI). Four male motor complete (ASIA-A) participants were enrolled in this study. They were trained to walk supported by FES using progressive interval exercise training on a motorized treadmill. We used distance walked to muscle fatigue during continuous treadmill ambulation as the primary outcome measure. Despite varied responses, all subjects increased their ambulation capacity. We conclude that FES-supported interval training offers a useful and effective strategy for strength-endurance improvement in the large muscle groups of the lower limb in motor complete SCI. We believe that this training protocol offers a viable alternative to that of continuous walking training in people with SCI using FES to aid ambulation.
