Increased risk of shoulder injury during shoulder flexion and abduction activities, specifically when the elbow travels below the shoulder during shoulder abduction. Risk is compounded with a winged scapula condition. Paradoxically, avoiding full range of motion (ie: not initiating deltoid exercises from a fully adducted position) may not allow the Supraspinatus to be fully strengthened, since it is more fully activated at these initial degrees of shoulder abduction/flexion. Once an injury has occurred, however, range of motion is typically restricted on the shoulder press. See shoulder abduction force vector diagram.
– Examples of affected exercises:
– Shoulder Press
– Upright Row
– Lateral Raise
– Example preventative/corrective exercises:
– Front Lateral Raise
– Lying Lateral Raise
