The Elbow Pronation Test measures how far the client can rotate the forearm inward. It is useful for tracking forearm rotation, comparing sides and adding context to gripping, lifting, racquet sports, throwing and daily hand use.
A client may report difficulty turning the palm down, using tools, gripping in certain positions or rotating the forearm during sport. The Elbow Pronation Test provides a practical way to measure forearm rotation and record side-to-side differences.
The MAT article describes the client seated or standing upright with the elbow tucked into the trunk, elbow flexed to 90 degrees and thumb facing upward. The device is held upright alongside the forearm at 0 degrees before the client rotates the forearm inward. The MAT source lists 80 degrees as the ideal pronation aim and states that typical pronation is around 75–80 degrees.
Test name: Elbow Pronation Test
Purpose: Assess forearm pronation ROM
What it assesses: Ability to rotate the forearm inward
Equipment: Measurz inclinometer
Key finding: Pronation angle in degrees
Best used with: Elbow supination, elbow flexion/extension, wrist ROM, grip strength and sport-specific upper-limb tests
Key limitation: Shoulder and trunk rotation can falsely increase the score
The Elbow Pronation Test measures forearm rotation into pronation. In simple terms, it records how far the client can rotate the forearm so the palm turns downward or inward, depending on the starting position.
It is used to assess forearm rotation ROM, compare sides and track progress. It may be relevant for daily hand tasks, lifting, throwing, racquet sports, grip tasks and upper-limb rehabilitation or training.
It measures forearm pronation ROM in degrees. It does not measure grip strength, wrist mobility, elbow stability, shoulder rotation or pain source.
Active pronation is measured when the client rotates the forearm inward themselves. Passive ROM may be measured if the professional assists the forearm. Record the method and do not compare active and passive results as the same score.
Throwers, racquet sport athletes, gym clients, combat sport athletes, manual workers, musicians and clients where forearm rotation is relevant.

Notes for side, pain, symptoms, active/passive method, elbow position and compensation
Ask the client to sit or stand upright. Keep the elbow tucked into the side of the trunk with 90 degrees of elbow flexion and the thumb facing up toward the ceiling. Hold the smart device upright alongside the forearm at 0 degrees. Ask the client to rotate the forearm inward as far as possible. Follow the forearm or align with the end position, then pause and save the result.
Record pain, tightness, wrist compensation, shoulder movement or trunk rotation.
Record pronation in degrees. The MAT source lists 80 degrees as the ideal aim and describes typical pronation as 75–80 degrees.
A lower score may suggest reduced pronation ROM under the tested method, but interpretation should include supination ROM, wrist ROM, elbow symptoms, grip findings and functional task demands.
Evidence level: Level 2, related or closest available reference values.
Use 75–80 degrees as practical context and 80 degrees as the MAT aim. Prioritise side comparison and baseline retesting.
A 2021 wrist-motion validation study included forearm pronation and supination and reported good-to-excellent reproducibility for smartphone-based wrist/forearm ROM measurement, especially with repeated testing and external sensor support. This supports the use of standardised digital measurement while still accounting for learning effects and measurement error.
Common errors include elbow moving away from the trunk, shoulder internal rotation, trunk rotation, wrist deviation, inconsistent device alignment and failing to record active/passive method.
Use this test to monitor forearm rotation, compare sides, guide exercise selection and add context to gripping, throwing, racquet work, manual tasks and wrist loading.
Record side, pronation angle, active/passive method, pain score, symptom location, elbow position, thumb starting position, forearm device placement, wrist compensation, comparison side and retest score.

It measures how far the forearm rotates inward.
The MAT source lists 80 degrees as the ideal aim, with typical pronation around 75–80 degrees.
This helps reduce shoulder and trunk compensation.
No. Pronation is forearm rotation and should be recorded separately from wrist ROM.
The Elbow Pronation Test measures inward forearm rotation.
Keep the elbow at 90 degrees and tucked beside the trunk.
Record active/passive method.
Use 80 degrees as a practical aim.
