Active vs passive range of motion full#

Additional force applied at the end of the available ROM is defined as stretching. In animals, passive ROM is performed by the therapist. Passive ROM is motion of a joint that is performed without muscle contraction within the available ROM, using an external force to move the joint. Progression through active assisted and active ROM follows, and when appropriate, some resistance to motion may be introduced for strengthening. It is generally appropriate to initiate passive ROM as soon after injury or surgery as possible provided there are no contraindications. In each situation, a load is produced on the soft tissues that helps to maintain the articular cartilage, muscles, ligaments, and tendons in a healthy state. Movement may be passive, active assisted, or active. 2 To maintain ROM, the joints and muscles must be periodically moved through their available ranges. ROM exercises are useful to diminish the effects of disuse and immobilization. In general, muscles that cross multiple joints may lose functional excursion easier than those that cross only one joint.

Some muscles, such as the biceps brachii and the rectus femoris muscles, cross two joints. The functional excursion may be affected by the joint it crosses, particularly if joint motion is restricted. 1 This is the distance that a muscle is able to shorten after it has been maximally elongated. Muscles also have a ROM, which is termed the functional excursion of muscles. 1 ROM is commonly measured with a goniometer, and each joint has characteristic angles, such as flexion and extension of the stifle, and flexion, extension, abduction, adduction, and internal and external rotation of the hip (Appendix 3). The structure of the joint and the volume, integrity, character, and flexibility of the soft tissues that surround the joint affect joint motion.

The full motion that a joint may be moved through is termed the ROM.
