What movements occur at the acromioclavicular joint?
The AC joint is a plane type synovial joint, which under normal physiological conditions allows only gliding movement. As it attaches the scapula to the thorax, it allows an additional range of motion to the scapula and assists in arm movement such as shoulder abduction and flexion.
How do you strengthen the AC joint in your shoulder?
Best AC Joint Exercises
- Neck rotation.
- Shoulder rolls.
- Neck stretches.
- Shoulder blade squeeze.
- Laying down shoulder flexion.
- Standing shoulder extension.
- Goalpost stretch.
How do I stop my AC joint from hurting?
Type I or II AC joint injury treatment
- Icing the shoulder.
- Putting your arm in a sling to decrease motion.
- Taking NSAIDs, like ibuprofen or naproxen, to help with pain.
Why does my AC joint hurt?
Most often, trauma, such as a fall directly on the outside of the shoulder, causes an AC joint injury. Overuse (repeated lifting of heavy weights or objects overhead with poor mechanics) also can result in an AC joint injury. AC joint injuries are most common in people younger than age 35.
What joint mobilization technique would be the most appropriate for a person suffering from shoulder impingement?
If pain is the primary factor limiting glenohumeral AROM in individuals with shoulder impingement, the MWM technique may be more effective at decreasing pain, resulting in better ROM outcomes. Additionally, the MWM technique may result in improved ROM as it is performed during active shoulder motion.
What stabilizes the acromioclavicular joint?
The AC joint is stabilized by the two sets of ligaments; A pair of intrinsic ligaments found within the articular capsule; the superior and inferior acromioclavicular ligaments. A single extrinsic ligament found outside the joint capsule; the coracoclavicular ligament.
How do you fix AC joint impingement?
Surgery. Shoulder decompression surgery is a common surgery for AC joint impingement. Also known as an Acromioplasty, it involves removing part of the bone and ligaments from the AC joint. The rationale is that the AC joint and ligaments are pressing on and injuring the rotator cuff tendons.
Can Massage Help AC joint?
No for massage. I would recommend strengthening of the muscles in the area of the shoulder to give support to the AC joint. Deep tissue massage would lengthen the muscles and make the joint more unstable.
What are the signs and symptoms of an acromioclavicular joint injury?
How Does It Feel?
- General shoulder pain and swelling.
- Swelling and tenderness over the AC joint.
- Loss of shoulder strength.
- A visible bump above the shoulder.
- Pain when lying on the involved side.
- Loss of shoulder motion.
- A “popping” sound or feeling that your shoulder “catches” with movement.
What is shoulder mobilization and when is it used?
Shoulder mobilization is commonly used in clinical practice. It is applied in cases where the ROM is restricted. Shoulder mobilization (Maitland technique) is described on this page. The shoulder comprises of glenohumeral joint, scapulothoracic joint, sternoclavicular joint, and acromioclavicular joint.
What is the starting position of a clavicle therapist?
The patient starting position is the same as described above. However, the therapist’s middle and ring fingers are over the superior aspect of the posterior edge of the lateral clavicle. Therapist moves the shoulder girdle into depression and retraction until posterior rotation of the clavicle ceases.
What is the acromioclavicular joint?
The Acromioclavicular Joint, or AC Joint, is one of four joints that comprises the Shoulder complex. The AC Joint is formed by the junction of the lateral clavicle and the acromion process of the scapula and is a gliding, or plane style synovial joint.
How do you palpate the anterior surface of the clavicle?
Following the taking of a history and observation the therapist palpates the anterior surface of the head of the clavicle. From a position of full retraction the patient is instructed to pull their shoulder girdles into protraction.
