The Shoulder Horizontal Abduction Test measures how far the arm can move away from the body in the transverse plane from a 90-degree flexed position. It is useful for tracking shoulder mobility, comparing sides and adding context to throwing, pressing and upper-body movement.
A client may feel restricted moving the arm backwards from a forward-reaching position, or an athlete may need shoulder transverse-plane ROM tracked for throwing, pressing or sport-specific movement. The Shoulder Horizontal Abduction Test provides a practical way to measure this movement.
The MAT article describes the client seated or standing with the arm flexed in front of the body at 90 degrees. The device is placed on top of the humerus, transverse-plane mode is used, and the client horizontally abducts the shoulder away from the body. The procedure note lists at least 130 degrees as the practical target; the following line appears to contain a likely wording inconsistency by referring to 180 degrees of shoulder abduction rather than horizontal abduction.
Test name: Shoulder Horizontal Abduction Test
Purpose: Assess horizontal abduction ROM
What it assesses: Transverse-plane movement away from the body
Equipment: Measurz inclinometer with transverse-plane function
Key finding: Horizontal abduction angle in degrees
Best used with: Horizontal adduction, shoulder external rotation, shoulder flexion, thoracic rotation and throwing assessment
Key limitation: Trunk rotation and scapular movement can affect the score
The Shoulder Horizontal Abduction Test measures how far the arm moves away from the body in the transverse plane from a shoulder-flexed position.
It is used to assess transverse-plane shoulder mobility, compare sides and track changes across sessions.
It measures shoulder horizontal abduction ROM. It does not isolate glenohumeral motion, measure strength or diagnose shoulder symptoms.
Active ROM is measured when the client moves the arm. Passive ROM may be measured if assisted. Record the method.
Throwers, swimmers, gym clients, racquet sport athletes, overhead athletes and clients with transverse-plane shoulder mobility goals.
Measurz inclinometer with transverse-plane function, treatment space, Measurz app and notes for side, pain, symptoms, active/passive method and trunk rotation.
Position the client seated or standing with the arm flexed in front of the body at 90 degrees. Place the device on top of the humerus and set the transverse-plane feature to zero. Ask the client to horizontally abduct the shoulder away from the body as far as possible. Save the result at maximal ROM.
Record horizontal abduction ROM in degrees. The MAT procedure note lists at least 130 degrees as the practical target. Because the page also contains a likely wording inconsistency, use the recorded protocol result, side comparison and baseline tracking as the main interpretation tools.
Evidence level: Level 3, limited exact norms for this protocol.
Use 130 degrees as the practical MAT procedure reference, but avoid treating it as a universal threshold.
Recent shoulder ROM evidence supports standardised device use, but transverse-plane movements can be more sensitive to trunk rotation and device alignment. Smartphone and sensor-based methods show promise for shoulder ROM, but standardisation remains important.
Common errors include trunk rotation, scapular retraction compensation, elbow bending, poor transverse-plane setup, inconsistent humerus placement and using an unclear reference value.
Use this test to monitor transverse-plane shoulder ROM, compare sides and add context to throwing, pressing, swimming and upper-body mobility programmes.
Record side, horizontal abduction angle, active/passive method, pain score, symptom location, trunk rotation, scapular movement, arm starting position, device placement and comparison side.

It measures how far the arm moves away from the body in the transverse plane.
The MAT procedure note lists at least 130 degrees, but the page contains a likely wording inconsistency elsewhere, so use baseline and side comparison as the main guide.
The movement occurs across the body, so transverse-plane measurement is more appropriate than a simple vertical-plane inclinometer reading.
No. It provides ROM information only.
The test measures horizontal abduction ROM.
Use transverse-plane measurement.
Control trunk rotation.
Use the MAT reference cautiously.
