How healthy is circuit resistance training following paraplegia? Kinematic analysis associated with shoulder mechanical impingement risk Linda M. Riek, DPT, PhD; Paula M. Ludewig, PT, PhD; Deborah A. Nawoczenski, PT, PhD
Aim • Determine whether wheelchair-based circuit resistance training (CRT) exercises place shoulder at risk for mechanical impingement. • Relevance • Shoulder pain is significant problem in spinal cord injury population. • Preventing shoulder impingement and maintaining shoulder health while performing CRT are of utmost importance.
Method • Created mechanical impingement risk score for each CRT exercise: • Combined scapular and glenohumeral kinematic and exposure data with 18 individuals with paraplegia and without substantial shoulder pain.
Results • Mean mechanical impingement risk scores at 45–60 humerothoracic elevation rank-ordered from lowest to highest as per subacromial mechanical impingement risk: • Overhead press. • Lat pulldown. • Chest press. • Row. • Rickshaw. • Mean mechanical impingement risk scores at 105–120 humerothoracic elevation rank-ordered from lowest to highest as per internal mechanical impingement risk: • Lat pulldown. • Overhead press.
Conclusion • Highest subacromial mechanical risk: • Rickshaw. • Highest internal mechanical impingement risk: • Overhead press and lat pulldown. • Rickshaw is most concerning exercise. • Greatest combination of magnitude and exposure corresponding with increased subacromial mechanical impingement risk.
