Radiographic Findings in the Lower Extremity Joints of Long-Term Users of Implanted Standing Neuroprostheses with Spinal Cord Injuries Open
At an average of 5 years after implantation, regular and independent weight bearing in 4 higher-than-average users of a neuromuscular prosthesis does not appear to promote lower extremity joint degeneration.
