Shoulder Abduction ROM
Active shoulder abduction is the arc of arm elevation in the frontal plane, from the side of the body to fully overhead. It is used clinically to assess glenohumeral joint mobility, rotator cuff function, and subacromial impingement. Norms are based on right-shoulder measurements using a digital inclinometer in a large Australian community sample (Gill et al., 2020). Abduction values tend to run lower than flexion values at most ages, reflecting the biomechanical constraint of the acromion during lateral elevation. The gap varies across age groups and is typically larger in younger adults.
How to Perform This Test
- Equipment
-
- Digital inclinometer or goniometer
- Firm chair or standing space
- Steps
-
- Stand or sit upright with the arm relaxed at the side in the anatomical neutral position (0 degrees).
- Raise the arm sideways in the frontal plane as high as possible without bending the elbow, hiking the shoulder, or side-bending the trunk.
- The assessor places a digital inclinometer on the lateral aspect of the forearm.
- Record the angle at maximum elevation.
- Perform on both sides; right-shoulder values are reported on this site.
- Scoring
Record the angle in degrees at maximum active lateral elevation. Higher values indicate greater shoulder abduction range of motion.
- Notes
Norms on this site are based on right-shoulder measurements. Left-shoulder values are typically within 1-3 degrees of right-shoulder values in the Gill 2020 dataset.

Frequently Asked Questions
What is a normal shoulder abduction range of motion?
For adults aged 20–54, the median active shoulder abduction (right shoulder) is approximately 156–164 degrees. Values decline with age, reaching around 124–132 degrees by age 80–84. Full abduction is considered 180 degrees; values below 150 degrees in adults under 60 may warrant further assessment.
How does abduction ROM compare to flexion ROM?
Shoulder abduction is typically 10–15 degrees lower than flexion at every age group. This is partly because the acromion creates a physical impingement barrier during lateral elevation, and partly because flexion has a slightly more favourable biomechanical path for the rotator cuff.
Why does shoulder abduction decline with age?
The same age-related factors affect abduction as flexion: reduced capsule flexibility, muscle shortening, and degenerative joint changes. Abduction may be more sensitive to rotator cuff pathology, which becomes more prevalent after age 60.
