 The efficacy of FESassisted walking with incomplete SCI individuals, both overground and on a treadmill, has previously been assessed by monitoring walking speed, stride length, endurance, cadence, the physiological and oxygen cost, body weight support treadmill, and by performing observational gait analysis and manual muscle testing 1,2,3,4,5,6. However, these methods do not provide a means of measuring changes in fitness or for accurately monitoring improvements in voluntary muscle function.
