Percent bone mineral density changes in chronic spinal cord injury patients receiving functional electrical stimulation.

<p>The figure represents the forest plot of percent bone mineral density (BMD) changes from baseline in the chronic spinal cord injury patients receiving functional electrical stimulation (FES) training at (A) the 3rd, (B) the 6th, and (C) the 12th month following intervention; (D) forest plot of the percentage of bone mineral density (BMD) changes from baseline categorized by training frequency at the 6th month post-FES intervention.
