What is the normal range of wrist motion?

Whether the hand can move smoothly is usually determined by the wrist joint. If you want your wrist joint to move well, you need to protect your wrist joint well. However, the wrist joint is a relatively complex part, which includes many joints. In fact, to judge whether your wrist joint is injured, there is a normal range of movement of the wrist joint, but there are differences between each joint, so the range is also different.

What is the normal range of wrist motion?

The hand and forearm are stretched out in a straight line, with the palm facing down, which is the 0° position of the wrist joint.

Flexion (palmar flexion): Bend your wrist downward toward your palm, approximately 50-60°.

Extension (dorsiflexion): Lifting your wrist upward toward the back of your hand is dorsiflexion, about 30-60°.

Ulnar deviation: When the wrist is straight, the palm is tilted towards the little finger, which is ulnar deviation, about 30-40°

Radial deviation: When the wrist is straightened and the palm tilts toward the direction of the thumb, it is radial deviation, about 25-30 degrees.

Reference values ​​for shoulder joint range of motion:

Forward flexion: It is to raise the body horizontally in front of you. The maximum height you can raise the body to is completely vertical, about 70-90°.

Extension: The action of lifting your arms backwards along the sides of your body is extension, about 40 degrees.

Abduction: Lateral raises are all about abduction, about 80-90 degrees. However, the maximum abduction angle can be when the arm is completely vertical and the arm is close to the ear, which is 180°. This is because the shoulder girdle is involved in the movement as a whole, and the glenohumeral joint (shoulder joint in a narrow sense) is only abducted to about 90°.

Adduction: Stretch your arm and touch the opposite leg with your hand, which is the adduction of the shoulder joint. About 20-40°

Internal rotation: Put your arms on both sides of the body, bend your elbows to 90 degrees, turn your forearms inward, and when your hands can touch your stomach, this is the maximum angle of internal rotation. About 70-90°.

External rotation: The movement in the opposite direction of internal rotation is external rotation. About 40-50°.

Reference values ​​for elbow range of motion:

Flexion: Flexion is bending the arm. About 135-150°. Generally, when the arm is bent, the fingers can be easily placed on the shoulder, and the elbow joint is flexed.

Stretch: When you stretch your arms and form a straight line, it is 0°. Many people have hyperextension, which means stretching a little further than 0°, called hyperextension, about 10-15°.

Keep your arms tucked tightly against your body, bend your elbows at 90 degrees, make fists and raise your thumbs, with your thumbs pointing upwards, which is the 0 degree position.

Pronation: Rotate your forearm so that your palm faces downward, about 80-90 degrees.

Supination: Rotating in the opposite direction of pronation, with the palm facing up, is supination, about 80-90°.
