Study conducted to determine how surface functional electrical stimulation (FES) of trunk muscles affects wheelchair propulsion biomechanics and metabolic responses. A total of 11 people with spinal cord injuries who used wheelchairs participated in the study. The participants pushed on a dynamometer at a speed of 1.34 meters per second for 3 trials. The trials lasted a total of five minutes each. The results indicated that the participants who were assigned higher stimulation rates as applied to the abdominal and lower back muscles produced higher propulsion power output, and increased their mechanical efficiency. The authors conclude that using FES on trunk muscles may enable people with spinal cord injuries who use wheelchairs to more efficiently propel their wheelchairs.
