Rotator cuff and range of motion of the Subscapularis, Supraspinatus, Infraspinatus, and Teres minor muscles within the rotator cuff. Passive exercises include internal and external rotation of the shoulder joint, as well as flexion and extension of the shoulder.As progression increases after 4–6 weeks, active exercises are now implemented into the rehabilitation process. Active exercises allow an increase in strength and further range of motion by permitting the movement of the shoulder joint without the support of a physical therapist. Active exercises include the Pendulum exercise (as shown in Image 2), which is used to strengthen the Supraspinatus, Infraspinatus, and Subscapularis. External
Mucous sheaths of the tendons around the ankle Mucous sheaths of the tendons around the ankle The mucous sheaths of the tendons around the ankle protect tendons in the ankle. All the tendons crossing the ankle-joint are enclosed for part of their length in mucous sheaths which have an almost uniform length of about 8 cm. each. On the front of the ankle the sheath for the Tibialis anterior extends from the upper margin of the transverse crural ligament to the interval between the diverging limbs of the cruciate ligament; those for the Extensor digitorum longus and Extensor hallucis longus reach upward to just above the level of
