Prevalence of shoulder discomfort in paraplegic subjects

The annual incidence of acute spinal cord injury, as reported in the National Spinal Cord Injury Statistical Center, was estimated to be approximately 40 cases per million, or approximately 11.000 new cases in the United States each year (1). In subjects with spinal cord injury, overstress of the upper extremities occurs not only during daily life activities, but also utilizing wheelchair. The aim of this study is to determine the prevalence of shoulder discomfort in subjects affected by paraplegia living in our country area and evaluate the associated risk factors negatively affecting the shoulder function.
