Arm is being pinched under the AC Joint while raising arm
Tendons having accumulated scar tissues and irritated trigger points
Rotator cuff consists of 4 muscles stabilizing your shoulder. If these muscles are partially torn, pain increases with limited range of motion
Pain can increase at the end range of elevation or while crossing your arm across your chest
Nerve bundles are compressed under the collarbone (Clavicle) by scalene and pectoralis muscles
After the surgery, rehab program focuses on improving range of motion, strength and function
Upper Crossed Syndrome is a natural muscle imbalance pattern of human’s upper body. People tends to develop tightness in their chest muscle (Pectoralis), upper trapezius, levator scapula and weakness in their lower trapezius, serratus anterior muscles. This pattern represents with forward head and rounded shoulder posture.
Thus, we should be careful about our posture and need to do proper matching exercise program with stretching and strengthening those muscle groups.
Scar Tissues and Trigger points inhibit activation of muscles. Once it is released with appropriate Manual Therapy, your muscles will be activated and coordinated naturally
Therapy: Trigger Point Therapy, Graston Instrument, Vibrocurssor Therapy, Stretching Therapy
Shoulder Girdle sits on rib cages and thoracic spine. If this pillar is slouched forward, it increases stress on shoulder joint while doing arm elevation. It can cause shoulder impingement.
Therapy: Upper/Mid Back Adjustment (Manipulation), Spine mobility & Posture exercise program
With arm elevation, healthy shoulder shows this movement:
If scapula is tilting forward due to muscle imbalance, the inferior tip of scapula is being lifted from the rib cages (Winging scapula) causing shoulder impingment.
Too Strong or tight chest muscle and weak back muscle breaks the proper agonist-antagonist strength ratio resulting in rounded shoulder posture. Rehab should emphasize on:
Strengthening
Stretching
Dynamic core exercise with shoulder movement is very effective in the final stage of shoulder rehab. Strong trunk and scapula muscles enable arms to move easily with spending less energy.
