1. INJURY PREVENTION AT THE DESK Ron Schenk PT, PhD Dean of Health and Human Services Associate Professor Physical Therapy Daemen College

2. Objectives Identify the anatomical areas susceptible to injuries and differentiate the causes, signs and symptoms of musculoskeletal disorders. Identify and implement correct methods for controlling risk factors. Understand the importance of posture in reducing risk. Apply repeated movement principles to prevent injury

3. Talking Points Musculoskeletal disorders (MSDs) are injuries and disorders that affect human movement or the musculoskeletal tissues (muscles, tendons, ligaments, nerves, discs, blood vessels…) Work related MSDs include carpal tunnel syndrome, tendonitis, thoracic outlet syndrome, neck and low back tension syndromes. Work related MSDs are also referred to as repetitive motion injuries, repetitive strain injuries, cumulative trauma disorders, occupational cervicobrachial disorders, overuse syndrome, regional musculoskeletal disorders, soft tissue disorders.
