The Wrist Flexion Test measures how far the hand bends forward toward the palm side of the forearm. It can be assessed actively or passively using a goniometer, inclinometer or smartphone-based process. The result helps compare sides, monitor symptoms and add context to gripping, pressing, weight-bearing, racquet sports, lifting and hand function.
A client may report difficulty bending the wrist during gripping, lifting, racquet sports, floor-based exercise or daily tasks. Another client may show reduced wrist flexion on one side or compensate through the fingers and forearm.
The Wrist Flexion Test helps quantify wrist movement in degrees. The result is most useful when finger position, forearm position, pain and compensation are recorded consistently.
Test name: Wrist Flexion Test
Purpose: Measure wrist flexion range of motion
Movement: Hand bending toward the palm side of the forearm
Joint/body region: Wrist
Plane: Sagittal plane
ROM type: Active ROM, passive ROM or both
Score: Degrees of wrist flexion
Equipment: Goniometer, inclinometer, smartphone ROM tool or Measurz ROM workflow
Best used with: Wrist extension, radial deviation, ulnar deviation, grip strength, push-up, plank, racquet sport and lifting assessments
Key limitation: Finger position, forearm position and compensation can affect the result
The Wrist Flexion Test measures movement of the hand toward the palm side of the forearm. It may be performed with the forearm supported on a table or with the arm in another standardised position.
Finger position should be recorded because finger extension or finger flexion can change tension through the wrist and forearm.
The test is used to quantify wrist flexion, compare sides and monitor progress over time.
It may help inform:
Grip and hand function monitoring
Upper-limb strength exercise setup
Weight-bearing hand tasks
Racquet and stick sport movement
Pain and symptom tracking
Progress across sessions
The test measures wrist flexion ROM in degrees.
It may be influenced by:
Radiocarpal and midcarpal movement
Finger position
Forearm pronation/supination
Elbow position
Pain or symptoms
Grip tension
Client effort
Device placement
Professional stabilisation
It does not explain the cause of reduced wrist flexion by itself.
Active wrist flexion measures how far the client can bend the wrist using their own control.
Passive wrist flexion measures available range when the professional guides the hand.
Active and passive values should be recorded separately because they can differ due to pain, control, strength, symptoms or available joint range.
This test may be useful for gym clients, manual workers, racquet sport athletes, climbers, musicians, desk workers and anyone where wrist movement affects training, work or daily function.
Goniometer, inclinometer or smartphone ROM tool
Table or supported surface
Pain scale
Measurz for recording ROM, pain and symptoms
Optional towel support
Optional comparison side notes
Position the client sitting with the forearm supported on a table.
The forearm may be pronated, neutral or supinated depending on protocol. Record the position.
Stand or sit beside the tested wrist with clear access to landmarks.
Start with the wrist in neutral and fingers relaxed unless using a specified finger position.
Stabilise the distal forearm to reduce forearm movement.
For active ROM, ask the client to bend the wrist forward as far as comfortably possible.
For passive ROM, gently guide the wrist into flexion until the first firm endpoint, symptom limit or compensation threshold.
For goniometry, commonly align the axis over the triquetrum or lateral wrist region, stationary arm along the ulnar midline of the forearm toward the olecranon and moving arm along the ulnar midline of the fifth metacarpal.
Place the inclinometer consistently on the dorsum or side of the hand according to your protocol and record placement.
Ask about wrist pain, forearm stretch, finger tension, stiffness, pinching, symptom location and whether symptoms are familiar.
Stop if pain increases sharply, symptoms spread, the client guards or compensation dominates.
Record active/passive method, side, degrees, pain score, symptom location, forearm position, finger position, device used and compensation.
One to three trials may be used. Record best, average or selected trial consistently.
Use the same forearm position, finger position, device, landmarks and endpoint each session.
The score is recorded in degrees.
A higher value means more wrist flexion under the tested setup. A lower value means less wrist flexion compared with baseline, the other side or related upper-limb findings.
Interpretation is stronger when paired with pain score, symptom location, active/passive comparison, wrist extension, radial and ulnar deviation, grip strength, weight-bearing tolerance, racquet sport tasks or work demands.
The result does not explain the cause of reduced or painful wrist flexion by itself.
A 2025 systematic review found that smartphone sensor and photography methods for hand and upper-extremity ROM are promising, but reliability and validity vary based on the joint, movement and measurement protocol.
A 2023 study using smartphone images and automatic hand pose estimation highlights the growing role of image-based hand and wrist ROM tools, while also reinforcing that these approaches require careful validation before replacing consistent clinical measurement.
Common errors include forearm movement, changing finger position, inconsistent forearm rotation, poor landmarking, forcing passive range, not recording symptoms and comparing active/passive values without labelling them.
Limitations include finger and tendon tension, pain, swelling, guarding, device variation, hand dominance and measurement error.
Use wrist flexion ROM to monitor wrist mobility, compare sides and add context to gripping, lifting, racquet sports, floor-based exercise, push-ups, planks and upper-limb strength work.
In Measurz, record baseline wrist flexion ROM in degrees using the goniometer, inclinometer or chosen device. Note active or passive method, side tested, pain score, symptom location, forearm position, finger position, test position, device used and compensation.
Track progress across sessions and add related wrist extension, radial deviation, ulnar deviation, grip strength, push-up, plank, racquet sport or work-task findings.

Plank Test
It measures how far the wrist bends toward the palm side of the forearm.
Both can be useful. Active ROM reflects controlled movement, while passive ROM reflects available range when guided.
Finger position can change forearm and wrist tissue tension, which may affect the result.
Record side, degrees, active/passive method, pain, symptoms, forearm position, finger position and compensation.
Use the same forearm position, finger position, device, landmarks and endpoint each session.
Wrist flexion ROM measures palm-side wrist bending.
Finger and forearm position should be standardised.
Active and passive results should be recorded separately.
Measurz should capture degrees, side, pain, method, position and compensation.
