Upper extremity range of motion norms
2026-09-04 · 8 min read
Five joints that lie to you in five different ways. Every reference number below assumes a stabilisation that most quick measurements skip.
The reference table
| Motion | Reference | Watch for |
|---|---|---|
| Shoulder flexion | 180° | Stabilise the trunk or you will measure the spine |
| Shoulder abduction | 180° | Allow external rotation past 90° or it jams |
| Shoulder external rotation | 90° | Measured at 90° abduction |
| Shoulder internal rotation | 70° | The first motion lost in a stiff shoulder |
| Elbow flexion | 150° | Extension is 0°; hyperextension reads negative |
| Forearm supination | 80° | Elbow tucked in, or the shoulder cheats |
| Forearm pronation | 80° | Same rule; a pencil in the fist helps |
| Wrist flexion | 80° | Fingers relaxed — a fist limits it |
| Wrist extension | 70° | The range that decides a push-up |
| Ulnar deviation | 30° | Radial deviation is 20° |
Reference ranges, not pass marks
Reference values below are the AAOS figures as reproduced in Norkin & White, Measurement of Joint Motion: A Guide to Goniometry. Published sources differ by roughly 5–10° at several joints; the AMA Guides use a partly different set. Treat them as reference ranges, not pass/fail cut-offs.
The substitutions to block
Shoulder flexion and abduction both recruit the trunk within a few degrees of the end range: a hand on the lateral ribcage stops the side-bend that otherwise buys twenty free degrees. Forearm rotation recruits the shoulder unless the elbow is held against the ribs.
Wrist flexion recruits the fingers — a clenched fist tightens the extensors and shortens the range you read. Ask for relaxed fingers and say why, or you will record a tendon length as a joint range.
Internal rotation is the one to measure carefully, because it is usually the first thing a stiff shoulder loses and the last thing it gets back.
Tie it to the arm, not the joint
The upper limb is used as a unit, which is why the standard patient-reported measure for it is scored across the whole arm rather than per joint. Pair a degrees column with a functional score — the DASH calculator does the arithmetic — and the two together say more than either alone.
A shoulder that gains fifteen degrees of external rotation while the functional score does not move is usually an avoidance problem rather than a range problem.
Tracking it
Measure both arms. Dominance produces small real differences, and a ten-degree asymmetry in a non-dominant limb reads differently from the same number in the dominant one.
Fix the position and record it. A shoulder measured supine and re-measured seated has not been re-measured.

Red flag — refer out
A range that worsens against treatment, or a sudden loss with pain out of proportion to the mechanism, is not a measurement problem. Stop measuring and refer.
