The Shoulder Abduction Test measures how far the client can raise the arm out to the side. It is useful for tracking overhead and lateral shoulder mobility, comparing sides and adding context to throwing, swimming, pressing and upper-body movement.
A client may struggle to raise the arm overhead from the side, feel restricted during lateral raises or experience asymmetry during sport and gym tasks. The Shoulder Abduction Test provides a repeatable way to measure this movement and track change over time.
The MAT article describes a seated or standing test with the arm straight at the side of the trunk, the Measurz inclinometer placed behind the arm, and the client abducting the shoulder as far as possible. The MAT source lists 180 degrees as the practical target.
Test name: Shoulder Abduction Test
Purpose: Assess shoulder abduction range of motion
What it assesses: Ability to raise the arm out to the side
Equipment: Measurz inclinometer
Key finding: Shoulder abduction angle in degrees
Best used with: Shoulder flexion, external rotation, internal rotation, thoracic mobility and overhead assessment
Key limitation: Trunk lean, scapular movement and shoulder shrugging can affect the score
The Shoulder Abduction Test measures the range available when the arm moves away from the side of the body in the frontal plane.
It is used to assess baseline shoulder abduction, compare sides and track overhead/lateral shoulder mobility.
It measures shoulder abduction ROM in degrees. It does not isolate glenohumeral abduction, measure shoulder strength or identify the cause of pain.
Active abduction is measured when the client raises the arm themselves. Passive ROM may be measured if the professional assists the arm. Record the method.
Overhead athletes, swimmers, throwers, gym clients, desk workers and clients with shoulder mobility goals.
Measurz inclinometer, treatment space, Measurz app and notes for side, pain, active/passive method, trunk lean and shoulder shrug.
Ask the client to sit or stand with the arm straight beside the trunk. Place the Measurz inclinometer behind the arm. Ask the client to abduct the shoulder as far as possible. Save the result when full ROM is achieved or pain/discomfort begins.
Record shoulder abduction in degrees. The MAT source lists 180 degrees as the practical target, but values may vary between clients.
Interpret with pain, scapular movement, thoracic mobility, shoulder rotation, side comparison and functional task demands.
Evidence level: Level 2, related or closest available reference values.
Use 180 degrees as a practical reference, not a strict universal threshold.
Shoulder ROM measurement reliability depends on consistent landmarks, device placement and movement standardisation. A systematic review of motion-tracking and sensor-based shoulder ROM tools reported moderate to good reliability across several technologies, including smartphone applications and digital inclinometers.
Common errors include trunk leaning, shoulder shrugging, elbow bending, inconsistent device placement and pushing into pain.
Use this test to monitor overhead/lateral shoulder ROM, compare sides and guide related shoulder rotation, strength or thoracic mobility testing.
Record side, abduction angle, active/passive method, pain score, symptom location, trunk lean, shoulder shrug, scapular notes, comparison side and progress across sessions.
