Peak forces of the rotator cuff muscles during activity of daily livings performed by a wheelchair user

摘要

The prevalence of the impingement syndrome, leading to shoulder pain, is important in wheelchair users such as patients with spinal cord injury (Akbar et al. 2007). According to epidemiologic studies (Aim et al. 2008), the most painful activities for these wheelchair users are wheelchair propulsion, self-care activities and lifting an object from overhead. Despite the pain experienced during a variety of movements, previous biomechanical analyses have focused on the forces and movements applied at the upper extremity joints during wheelchair propulsion, likely because this activity is obviously differentiating for wheelchair users.
