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.
