The range of motion of each joint of the human body

The range of functional activity of each joint of the human body is to check the range of motion of the joint of the patient and to diagnose whether there is abnormality of joint activity. The clinical significance of the range of functional activities of various joints of the human body: abnormal results: abnormal joint activities, suggesting that there are lesions in the parts that cannot be normally active, and more detailed examination is needed. People who need to be examined: people whose joints cannot move freely. Basic Information Specialist classification: growth and development check classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Inappropriate people: no special requirements. Normal value The neck is placed in the neutral position first, and the neck activity is 35-45° for the flexion, 35-45° for the posterior flexion, and 60-80° for each of the left and right lateral flexion. The waist is erect, the waist is straight and natural, and its activity is 90° forward, 30° backward, 30 for left and right sides, and 30° for left and right rotation. The shoulder joint is placed in the neutral position first, and its activity is 90° flexion, 45° posterior, 90° abduction, 40° adduct, 80° internal rotation, 30° external rotation, and 90° upward. The elbow joint is placed in the neutral position first, and its mobility is 140° flexion, 0～10° overextension, 80-90° pre-rotation, and 80°-90° post-rotation. The wrist and wrist joints are placed in a neutral position. Its activity is 35~60° for the back extension, 50°～60° for the palm, 25°～30° for the 桡, and 30°～40° for the ruler. The metacarpophalangeal joint is placed in the neutral position first, and its activity is 60-90° flexion of the metacarpophalangeal joint, and the straightness is 0°. The interphalangeal joint flexes 90° and extends straight 0°; the distal interphalangeal joint flexes 60～90 °, straighten 0°. The thumb joint is placed in the neutral position first, and its activity is 70° on the volar side; on the palm, pay attention to the degree of the thumb across the palm; flexion, the thumb joint 20-50°, the interphalangeal joint 90°; the adduction, extension The straight position is close to the side of the index finger. The hip joint is placed in the neutral position first, and its joint mobility is: flexion 145°, posterior extension 40°, abduction 30～45°, adduction 20～30°, internal rotation 40～50°, external rotation 40～50° . The knee joint was first placed in the neutral position, and its mobility was 145° flexion and 0° straight. When the knee flexed, the internal rotation was about 10° and the external rotation was 20°. 踝, the ankle joint of the foot is first placed in the neutral position, and its activity is 20~30° for the back extension, 40-50° for the plantar flexion; 30° for the inferior joint, 30-35° for the eversion; the dorsal extension of the metatarsophalangeal joint About 45°, the squat is about 30 to 40°. Clinical significance Abnormal results: abnormal joint activity, suggesting that there is a lesion in the site that is not normally active, and a more detailed examination is needed. People who need to be examined: people whose joints cannot move freely. Precautions Inappropriate people: no special requirements. Note the scope of the activity. Inspection process The joint protractor can be used to measure the range of motion of the joint and calculate the degree of its activity by angle. Normal degree or contrast with the healthy side, such as less than normal or healthy side, it is abnormal joint function. If the function is affected, it should be considered as joint dysfunction. When operating, the axis of the protractor should be aligned with the center of the joint, the sides of the protractor should be placed close to the limb, and aligned with the axis of the limb, and then the angle shown by the protractor should be recorded. This book uses the neutral 0 method, first determine the neutral position of each joint is 0. If there is no protractor inspection, it can also be estimated by visual method, but it is generally not accurate and is for reference only. Not suitable for the crowd There are no special taboos. Adverse reactions and risks No related complications and hazards.
