This study characterized the relative role of the hip and knee proprioceptors in triggering extensor spasms in people with spinal cord injury (SCI). Although extensor spasms are common in people with SCI, including veterans, the precise triggers for multijoint extensor spasms are not well understood. Results from this study emphasize the role of knee and hip proprioceptors, especially the biarticular sartorius muscle afferents, in initiating extensor spasms in SCI. This knowledge may help identify rehabilitation strategies for producing functional movements in people with SCI.
