The extension synergy for the lower extremity includes hip extension, adduction and internal rotation, knee extension, ankle plantar flexion and inversion, and toe plantar flexion. [ 1 ] Note that some muscles are not usually involved in these synergy patterns and include the lattisimus dorsi , teres major , serratus anterior , finger extensors ...
The Spencer technique (also known as the "7 stages of Spencer") is an articulatory technique used in Osteopathic medicine to help relieve restriction and pain at the shoulder. [1] Although variations exist, normally 7 steps are included. [2] Indications for the Spencer technique include adhesive capsulitis. [3] The following is a common ...
The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the shoulder joint is the most mobile joint in the body.
A dislocated shoulder can be treated with: arthroscopic repairs; repair of the glenoid labrum (anterior or posterior) [1] In some cases, arthroscopic surgery is not enough to fix the injured shoulder. When the shoulder dislocates too many times and is worn down, the ball and socket are not lined up correctly.
In anatomy, extension is a movement of a joint that increases the angle between two bones or body surfaces at a joint. Extension usually results in straightening of the bones or body surfaces involved. For example, extension is produced by extending the flexed (bent) elbow. Straightening of the arm would require extension at the elbow joint.
Flexion and extension describe the basic ways your body moves at its joints. Here's what that means for your workouts and training.
Shoulder replacement is a surgical procedure in which all or part of the glenohumeral joint is replaced by a prosthetic implant. Such joint replacement surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage. [1] Shoulder replacement surgery is an option for treatment of severe arthritis of the shoulder joint.
The Cunningham technique was originally published in 2003 and is an anatomically based method of shoulder reduction that utilizes positioning (analgesic position), voluntary scapular retraction, and bicipital massage. [7] If performed correctly most patients do not require analgesia for the performance of this technique.
