Spinal Cord Injured (SCI) paraplegics suffer from pathological changes in the lower extremities such as muscle degeneration, hormonal alterations and bone resorption. The aim of the present study was, with the help of finite element and image analysis, to evaluate the osteogenic response of the patella of paraplegic patients undergoing Functional Electrical Stimulation (FES). For this purpose, a patient that began a daily home based FES treatment 5 years after paralysation was monitored. Bone mechanical parameters were compared at the beginning of FES and after 3 years of treatment. According to our results, it is possible to conclude that application of long term FES treatment on denervated, degenerated muscles can be beneficial for bone growth in bones attached to the stimulated muscles.
