The Shoulder Horizontal Adduction Test measures how far the arm moves across the body at shoulder height. It can be assessed actively or passively using a goniometer, inclinometer, tape method or consistent ROM process. The result helps track cross-body shoulder movement, compare sides and add context to pressing, throwing, swimming, posterior shoulder mobility and upper-limb strength assessments.
A client may report tightness or symptoms when reaching across the body, setting up for pressing, following through during throwing or moving through swimming strokes. Another client may appear to gain cross-body range by rotating the trunk or letting the shoulder blade move instead of isolating shoulder movement.
The Shoulder Horizontal Adduction Test provides a way to measure cross-body shoulder ROM. It is different from shoulder adduction and should be recorded as its own test.
Test name: Shoulder Horizontal Adduction Test
Also known as: Cross-body adduction test when used as a movement assessment
Purpose: Measure shoulder horizontal adduction ROM
Movement: Arm moves across the body at shoulder height
Joint/body region: Shoulder complex
Plane: Transverse plane
ROM type: Active ROM, passive ROM or both
Score: Degrees, distance or movement position depending on protocol
Equipment: Goniometer, inclinometer, tape measure or Measurz ROM workflow
Best used with: Shoulder horizontal abduction, internal rotation, external rotation, throwing assessment, pressing and shoulder strength testing
Key limitation: Scapular protraction and trunk rotation can affect the result
The Shoulder Horizontal Adduction Test measures the movement of the arm across the front of the body at shoulder height.
It is commonly used as a cross-body shoulder ROM measure. It may provide information about posterior shoulder movement tolerance, but it should not be interpreted as a single-structure test.
The test is used to quantify cross-body shoulder movement, compare sides and track change.
It may help inform:
Posterior shoulder mobility monitoring
Throwing and racquet sport movement context
Pressing and upper-body gym movement
Swimming movement assessment
Pain and symptom tracking
Side-to-side comparison
Progress across sessions
The test measures shoulder horizontal adduction ROM under the chosen setup.
It may be influenced by:
Glenohumeral movement
Scapular protraction or stabilisation
Thoracic rotation
Posterior shoulder tissue tolerance
Pain or symptoms
Arm starting position
Measurement method
Testing position
Professional stabilisation
It does not explain the cause of movement difference by itself.
Active horizontal adduction measures how far the client can move the arm across the body using their own control.
Passive horizontal adduction measures available motion when the professional guides the arm.
Active and passive values should be recorded separately.
This test may be useful for throwers, swimmers, racquet sport athletes, gym clients, overhead workers and clients where cross-body shoulder movement is relevant.
Goniometer, inclinometer or tape measure
Treatment table, chair or standing space
Pain scale
Measurz for recording ROM, pain and symptoms
Optional video notes
Optional comparison side notes
Choose supine, sitting or standing and record the position.
Position the arm at shoulder height according to the selected method. Record elbow position and arm rotation.
Stand beside or above the client to observe trunk movement, scapular movement and symptom response.
Start with the arm in a standardised position before moving across the body.
Monitor or stabilise the scapula depending on the selected protocol. Record whether the scapula was stabilised or allowed to move.
For active ROM, ask the client to move the arm across the body as far as comfortably possible.
For passive ROM, gently guide the arm across the body until the first firm endpoint, symptom limit or compensation threshold.
Use a consistent shoulder axis and humeral reference if using degrees. If using distance, record the exact landmarks used.
Place the inclinometer consistently on the humerus or selected segment and record placement.
Ask about posterior shoulder stretch, anterior shoulder symptoms, pinching, stiffness, symptom location and whether symptoms are familiar.
Stop if pain increases sharply, symptoms spread, apprehension occurs, trunk compensation dominates or movement is not tolerated.
Record active/passive method, side, degrees or distance, pain score, symptom location, arm starting position, elbow position, scapular stabilisation, test position, device used and compensation.
One to three trials may be used. Record best, average or selected trial consistently.
Use the same position, starting angle, scapular stabilisation, device, arm rotation, endpoint and scoring method each session.
The score may be recorded in degrees, distance or position reached depending on the protocol.
A greater value may indicate more cross-body shoulder movement under the tested setup. A lower value may indicate less horizontal adduction compared with baseline, the other side or related shoulder findings.
Interpretation is stronger when paired with pain score, symptom location, active/passive comparison, internal rotation, external rotation, horizontal abduction, scapular control, throwing load, pressing or swimming findings.
The result does not identify the cause of movement difference by itself.
Horizontal adduction measurement depends heavily on whether the scapula is stabilised and how the endpoint is defined. General ROM research supports using consistent devices and procedures when measuring upper-limb ROM. A 2023 study of five goniometric devices found concurrent validity and reliability can vary by tool, reinforcing the value of repeating the same method across sessions.
A 2025 systematic review found smartphone sensor and photography methods for upper-extremity ROM are generally promising, but reliability and validity depend on the movement tested, device and protocol quality.
Common errors include confusing horizontal adduction with shoulder adduction, allowing trunk rotation, changing scapular stabilisation between sessions, inconsistent landmarks, forcing passive movement, not recording symptoms and comparing distance and degree methods directly.
Limitations include scapular contribution, thoracic rotation, protocol variability, pain, guarding, measurement error and active/passive differences.
Use shoulder horizontal adduction ROM to monitor cross-body movement, compare sides and add context to throwing, swimming, pressing, posterior shoulder mobility, upper-limb strength and sport movement assessments.
In Measurz, record baseline shoulder horizontal adduction ROM using the chosen method. Note active or passive method, side tested, pain score, symptom location, test position, arm starting position, elbow position, scapular stabilisation, device used, trunk rotation, scapular compensation and comparison side.
Track progress across sessions and add related internal rotation, external rotation, horizontal abduction, shoulder strength, throwing, swimming or pressing findings.

It measures cross-body shoulder movement at shoulder height.
No. Shoulder adduction moves the arm toward the side of the body, while horizontal adduction moves the arm across the front of the body.
Either approach may be used, but the method must be recorded and repeated consistently.
Both can be useful. Active and passive results should be recorded separately.
Record side, score, method, scapular stabilisation, pain, symptoms and compensation.
Shoulder horizontal adduction measures cross-body arm movement.
It is different from shoulder adduction.
Scapular stabilisation changes interpretation and must be recorded.
Measurz should capture score, side, pain, method, position and compensation.
