Following a complete spinal cord injury (SCI), individuals experience progressive bone loss, especially in the legs, with up to 70% of persons with SCI sustaining a fracture at some point during their lifetime. Fractures following SCI are costly to treat and more than half of patients experience a medical complication, requiring extended hospitalization, resulting in a substantial impact on their quality of life. To reduce the incidence of fractures, more effective rehabilitation strategies to prevent bone loss are needed. The goal of this research is to determine if bone health can be preserved using an indoor rowing exercise program in which the leg muscles are electrically stimulated using several, small surface electrode pads that are placed on the skin on the front and back thigh muscles. An encouraging case study has recently shown remarkable bone preservation in one individual with SCI who participated in an electrical stimulation rowing program, however, whether other individuals with SCI can achieve the same benefit is currently unknown.
