Study Notes
Effects of Immobilization
- Extended periods of immobilization can result in muscle tissue atrophy and contracture.
- Immobilization causes a decrease in bone density.
- It leads to articular cartilage degradation and loss of function.
- Immobilization results in regional osteoporosis, particularly in the affected area.
Muscular Effects
- Immobilization causes muscle fibers to atrophy, with slow-twitch fibers exhibiting greater atrophy compared to fast-twitch fibers.
- Excessive collagen fiber cross-links occur due to immobilization, leading to muscle stiffness and loss of function.
Active Free Exercises
- AROM stands for Active Range of Motion in the context of exercise.
- Active free exercises are used to maintain the normal range of joint motion.
- One of the primary goals of active free exercises is to maintain or improve joint mobility.
- The starting position for active free exercises is typically a neutral position.
- Muscle relaxation plays a crucial role in active free exercises, allowing for more effective movement.
- The primary purpose of teaching instructions for active free exercises is to ensure proper execution and minimize injury risk.
- The primary factor influencing the speed at which exercise should be done is the individual's comfort level and muscle control.
Physiological Effects
- Prolonged active free exercise increases heart rate, leading to increased circulation and heat production.
- Circulatory and respiratory cooperation improves with prolonged active free exercise.
- The starting position in active free exercises helps to establish a foundation for movement, reducing muscle strain and promoting proper execution.
Osteoporosis and Cartilage
- Regional osteoporosis is a consequence of prolonged immobilization, particularly in the affected area.
- Immobilization leads to articular cartilage degradation and loss of function.
- Prolonged immobilization results in decreased bone density, making the individual more susceptible to osteoporosis.

Description
This quiz covers active free range of motion (AROM) exercises, which are performed by the patient's own muscular efforts within the unrestricted range of motion without the assistance or resistance of any external force other than gravity. It includes localized and generalized exercises to strengthen specific muscle groups or use many muscles all over the body. Additionally, it explores the benefits of AROM exercises, such as relaxation and improving muscle function.
