5. What other exercise can you perform to get better at this motion? Why?

Answer 1

SCIENTIFIC JOINT NAME:

1. Shoulder- Glenohumeral joint ( ball and socket joint ) constituents humerus  and glenoid cavity of the scapula.
2. Elbow - Hinge joint constituents of humerus, radius and ulna.

JOINT MOTION :

1. Shoulder - External rotation, internal rotation, abduction , abduction, flexion and extension.
2. Elbow - Flexion and extension.

PLANE AND AXIS :

1. Shoulder- Shoulder joint rotate all three axis including longitudinal, lateral and vertical and and movement all three planes including transverse, sagital and frontal plane.
2. Elbow - Elbow allows movement forward and backward ( flexion and extension ) in sagital plane.

MUSCLE ACTION :

1. Shoulder - Posterior deltoid, middle deltoid , trapezius and biceps brachii muscles.
2. Elbow - Brachialis , biceps brachii , brachioradialis and triceps muscle.

Other exercise mainly - Active horizontal abduction exercise . It is slowly lift up the arm so hand is pointing to the ceiling .Hold this position for one to two second and than slowly lower to the initial position .It is a pain free range of motion.

Why

1. Helps to improve joint movement .
2. Relief joint pain
3. Maintain healthy .
