Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another. In biomechanics and strength training , ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [ 1 ]
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.
The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°. The nerves are primarily from the sacral spinal cord roots S1 and S2. Compression of S1 roots may result in weakness in plantarflexion; these nerves run from the lower back to the bottom of the foot.
The range of motion at the shoulder may be limited by pain. A painful arc of movement may be present during forward elevation of the arm from 60° to 120°. [4] Passive movement at the shoulder will appear painful when a downward force is applied at the acromion but the pain will ease once the force is removed. [2]
In human anatomy, the shoulder joint comprises the part of the body where the humerus attaches to the scapula, and the head sits in the glenoid cavity. [1] The shoulder is the group of structures in the region of the joint. [2] The shoulder joint is the main joint of the shoulder.
Extension of the hip or shoulder moves the arm or leg backward. [11] Even for other upper extremity joints – elbow and wrist, backward movement results in extension. The knee, ankle, and wrist are exceptions, where the distal end has to move in the anterior direction for it to be called extension. [13] [page needed]

Evaluation of passive and active range of motion: Neck range of motion should be assessed that may reveal a neck source of shoulder pain. The Apley scratch test specifically tests range of motion and in a normal exam, an individual should be able to reach C7 on external rotation, and T7 on internal rotation. Evaluation of distal pulses
