Study Notes
Shoulder Range of Motion
- The shoulder joint has a range of motion of 0-180° in flexion, allowing for full forward elevation of the arm.
- In extension, the shoulder joint can move 0-60°, enabling the arm to be moved backward.
- Abduction, or the movement of the arm away from the midline, has a range of 0-180°, allowing for full lateral elevation.
- Internal rotation, or the rotation of the arm inward, has a range of 0-70°, permitting the arm to be rotated inward.
- External rotation, or the rotation of the arm outward, has a range of 0-90°, allowing for the arm to be rotated outward.
- Horizontal abduction, or the movement of the arm away from the midline in the horizontal plane, has a range of 0-45°.
- Horizontal adduction, or the movement of the arm towards the midline in the horizontal plane, has a range of 0-135°.
Shoulder Range of Motion
- Shoulder flexion ranges from 0 to 180 degrees.
- Shoulder extension ranges from 0 to 60 degrees.
- Shoulder abduction ranges from 0 to 180 degrees.
- Shoulder internal rotation ranges from 0 to 70 degrees.
- Shoulder external rotation ranges from 0 to 90 degrees.
- Horizontal shoulder abduction ranges from 0 to 45 degrees.
- Horizontal shoulder adduction ranges from 0 to 135 degrees.
Shoulder Internal Rotation Position
- Internal rotation range of motion (ROM) is assessed in the supine position.
- Internal rotation manual muscle test (MMT) is performed in the prone position.
Shoulder External Rotation Position
- External rotation range of motion (ROM) is assessed in the supine position.
- External rotation manual muscle test (MMT) is performed in the prone position.
Shoulder Internal Rotation
- Scapula is responsible for stabilization
- Proximal wrist provides resistance
Shoulder External Rotation
- Scapula is responsible for stabilization
- Proximal wrist provides resistance
Elbow Extension
