Study Notes
Range of Motion
Definition
- The range of motion (ROM) refers to the extent of movement possible in a specific joint or series of joints.
Types of Movement
- Flexion: Movement that decreases the angle between two bones (e.g., bending elbow).
- Extension: Movement that increases the angle between two bones (e.g., straightening elbow).
- Abduction: Movement away from the midline of the body (e.g., raising arm out to the side).
- Adduction: Movement towards the midline of the body (e.g., bringing arm back to the body).
- Rotation: Movement around a central axis (e.g., rotating head from side to side).
- Circumduction: Circular movement (e.g., moving arm in a circle).
Measurement
- Goniometry: The process of measuring joint ROM using a goniometer.
- Active range of motion (AROM): The range of motion achieved by an individual's own muscle power.
- Passive range of motion (PROM): The range of motion achieved with external assistance.
Importance
- Injury prevention: Maintaining or improving ROM can help prevent injuries.
- Rehabilitation: ROM exercises are essential in physical therapy to restore function and mobility after injury or surgery.
- Performance enhancement: Increasing ROM can improve athletic performance and reduce risk of injury.
Understand the different types of movement, measurement techniques, and importance of range of motion in injury prevention, rehabilitation, and performance enhancement. Learn about flexion, extension, abduction, adduction, rotation, and circumduction.
