When muscles aren't used and exercised on a regular basis, they become weak and unable to support joint function and range of motion. As the person or body part being exercised grows stronger, different forms of resistance may be used to help provide additional strengthening benefits, such as through resistance bands, pressure from the therapist or weights, according to the Merck Manual Online Medical Library.
Anyone who is required to spend a lot of time in a wheelchair or on bed rest may benefit from passive range of motion exercises that help increase and improve circulation by keeping joints and muscles functioning and healthy, according to Family Friendly Fun, a website devoted to family fun and health and dealing with special needs and disability support.
Passive range of motion exercise helps prevent blood from pooling in the extremities or the lower torso, which may lead to skin breakdown known as decubitus ulcers or bedsores. Passive range of motion exercises also help promote increased cardiac capacity, which helps pump oxygen-rich blood to all cells and tissues in the body. Without regular movement , the joints in the body become stiff and unbending. In some who are unable to move, such as those who have been paralyzed, muscle atrophy and contractions may occur, which literally waste away muscle tissue and cause the limbs to curl inward toward the center of the body.
This can be extremely painful. Passive range of motion helps prevent joints from stiffening and helps increase joint health by keeping joints lubricated and flexible, according to Drugs. Exercising the joint helps keep them limber, which reduces pain caused by stiffness. The abbreviations stand for amyotrophic lateral sclerosis and muscular dystrophy, respectively.
Contractures are caused by atrophy and shortening of muscles or joints that are not used, resulting in painful deformities. Denise Stern is an experienced freelance writer and editor. She has written professionally for more than seven years.
The active range of motion here is produced by the hip flexor and quad muscles contracting and pulling your leg up. Standing, slowly bend your knee so the foot rises back toward your butt. The active range of motion here is contracting the hamstring muscles to pull your foot up to your butt without any outside help. You can think of control as the measurement for your active range of motion.
The more movement you can control, the more active range you have. Is your brain ready to explode or are you still with me? Just remember, with passive range of motion, you feel a stretch. With active range of motion you feel a contraction.
If you followed along with the examples above, you probably noticed that you didn't get anywhere near the same range of motion with the active movements as you did with the passive ones. The issue arises when that gap between passive and active is too big.
This difference tells us a story about our risk of pain, injury, or training plateaus. The two most common scenarios we see in this gap are:. Like, how did they get their arms past their head like that? This is a passive stretch where the weight of their upper body is pulling them down into deep shoulder flexion.
The issues start when that same person jumps up to a pull-up bar, loading an uncontrollable range of motion with their body weight. But the body will figure out a way and will start to compensate by using other joints to help accomplish the task. This will eventually result in aches, pain, and injuries. In my earlier years of lifting I was totally guilty of not having enough passive and active range to get into lifts like the squat.
The issue is, if we can't perfectly get into the position of the lift unloaded, then how can our tissue and joints be expected to handle it loaded? Without passive AND active range of motion, other parts of the body have to step in and this leads down the road to ouchies and being stuck under the bar.
Can I just say…this is horrible! You can apply this same thought to the bench and dips. The therapist mostly uses a strap or a band to secure the joint before assisting the movements. Initially, the patient may suffer a great deal of pain and weakness when performing these exercises.
However, with time, they have a great scope for gradual and lasting improvement in the range of motion around the affected joint. Active range of motion exercises — These exercises involve very little assistance from the physical therapist. They are most useful in cases of minor injuries that do not severely restrict the movement of body parts, but are painful, uncomfortable, or hindering nevertheless.
