Sports Massage: Enhancing Training, Participation and Recovery for Today's Athlete, 2nd Edition: Summary 74
Joint Considerations: • Synovial fluid is also created in the joint that acts a lubricant to prevent the tissues from overheating during movement • Joint capsule can shrink with immobilization so it’s important to move the joint to maintain the integrity of the joint capsule • Joint capsule contracture is a common complication following injures and can lead to a surgical release caused by the increased production of myofibroblasts • Techniques to prevent joint contracture and scar tissue include: circular friction, cross- fiber, and traction; performed in a multi- plane range of motion
Another neurological mechanism is called Synergistic Dominance. It is a compensatory mechanism and is the tendency of synergist (helper) muscles to overcompensate if the agonist muscles aren’t functioning at full capacity. For example, very commonly in running hip flexors will be tight and inhibit the glute max; the hamstrings (synergists) will then super compensate and perform more hip extension and become overworked although the hamstrings themselves are not inherently deficient. | HEALTHCARE CONSIDERATION Sport Injuries Precautions and indications for massage with sport injuries include: • Massage is contraindicated on acute site • Massage proximal/distal to the injury is safe • Keeps the blood flow going • Brings fluid to the area • Prevents joint contracture Most synovial joints have a joint capsule (set of connective tissue like a cocoon weaving around a joint that creates a negative pressure to increase stability).
Sports Injuries Injury Shoulder impingement
Description
One of the most common is shoulder impingement caused by improper articulation of the head of the humerus and the scapula. Head of the humerus and the scapula should move together but if instead the humerus pushes up into the scapula these structures (supraspinatus, biceps long head tendon, and subacromial bursa) will impinge between the two bones. To alleviate shoulder impingement, stimulate the hypotonic muscles by actively depressing the shoulders and retracting the shoulders back and stretching and lengthening the hypertonic muscles. Separation of the AC (Acromioclavicular) joint. Acromion process forms a canopy over the clavicle and is separated by an anterior/posterior force. Common in football and wrestling.
