From 90-180 degrees it is the trapezius and the serratus anterior. Adduction is carried out by the pectoralis major, latissimus dorsi, teres major and the subscapularis. Horizontal abduction and horizontal adduction of the shoulder (transverse plane) Medial and lateral rotation of the shoulder (also known as internal and external rotation).
In general, motion is classified according to the anatomical plane it occurs in. Flexion and extension are examples of angular motions, in which two axes of a joint are brought closer together or moved further apart. Rotational motion may occur at other joints, for example the shoulder, and are described as internal or external.
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.
Lateral rotation of the arm [16] The opposite of medial rotation of the arm. infraspinatus and teres minor, posterior fibers of deltoid Arm circumduction [17] Movement of the shoulder in a circular motion so that if the elbow and fingers are fully extended the subject draws a circle in the air lateral to the body.
External rotation of the shoulder with the arm at a 90-degree angle is an additional exercise done to increase control and range of motion of the Infraspinatus and Teres minor muscles. Various active exercises are done for an additional 3–6 weeks as progress is based on an individual case-by-case basis. [9]
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
By being so shallow the glenoid cavity allows the shoulder joint to have the greatest mobility of all joints in the body, allowing 120 degrees of unassisted flexion. Additional range of motion in shoulder flexion (typically up to 180 degrees in humans) is also accomplished by the great mobility of the scapula (shoulder blade) through a process ...
Range of motion tests external and internal rotation, abduction and adduction, passive and active weakness, and true weakness versus weakness due to pain. The Apley scratch test is the most useful: touch opposite scapular by reaching behind the head for adduction and external rotation and behind the back for abduction and internal rotation.
