Shoulder Flexion ROM
Active shoulder flexion is the arc of forward arm elevation from the anatomical position to full overhead reach. It is routinely assessed in clinical, sports, and occupational health settings to screen for rotator cuff pathology, adhesive capsulitis, and post-surgical recovery. Norms are based on right-shoulder measurements using a digital inclinometer in a large Australian community sample (Gill et al., 2020). Most participants were right-hand dominant, and right-shoulder values are the most commonly referenced in clinical literature. Left-shoulder values are typically within 1–3° of right-shoulder values in this dataset.
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 forward in the sagittal plane as high as possible without bending the elbow or rotating 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 elevation. Higher values indicate greater shoulder flexion 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 flexion range of motion?
For adults aged 20–54, the median active shoulder flexion (right shoulder) is typically 164–179 degrees. From age 55 onward, median values decline gradually, reaching around 140–156 degrees by age 80–84. Values below 150 degrees in adults under 60 may warrant clinical review.
Why does shoulder flexion decline with age?
Age-related decline in shoulder flexion is driven by reduced joint capsule extensibility, decreased muscle flexibility, and degenerative changes in the glenohumeral and acromioclavicular joints. The steepest decline in this dataset occurs after age 60, particularly in women.
Should I use left or right shoulder norms?
These norms are based on right-shoulder measurements. In the Gill 2020 dataset, left and right shoulder flexion values differ by only 1–3 degrees on average, so right-shoulder norms are appropriate for most screening purposes regardless of hand dominance.
Why do young males have P75 and P95 values at 180 degrees?
Full shoulder flexion reaches the anatomical ceiling of 180 degrees. Among adults aged 20–54, a substantial proportion can achieve full overhead range of motion, which causes P75 and P95 to stack at 180 degrees. This is expected and reflects genuine variation in the population rather than a data anomaly.
