A complete clinical guide to the ankle dorsiflexion test and mobility tracking

Key Takeaways

The ankle dorsiflexion test measures the range of motion in the talocrural joint, essential for assessing movement quality and injury recovery in physiotherapy and sports medicine.

Weight-bearing lunge test (WBLT) and knee-to-wall test are the most reliable and functionally relevant methods for assessing closed-chain dorsiflexion ROM.

Silfverskiöld test distinguishes gastrocnemius from soleus tightness by comparing ROM with knee extended versus flexed – a critical differentiation for targeted treatment.

Pabau’s digital forms and measurement tracking tools help clinicians standardize test documentation, track bilateral asymmetry, and monitor progress across serial assessments.

The ankle dorsiflexion test is a clinical assessment used to measure the range of motion available at the talocrural joint. This standardized screening tool helps physiotherapists, sports medicine clinicians, and podiatrists identify restrictions in ankle mobility that may limit functional movement, increase injury risk, or slow rehabilitation progress.

Dorsiflexion—the upward movement of the foot toward the shin—is essential for everyday activities like walking, climbing stairs, and running. Limited ankle dorsiflexion ROM has been associated with ankle sprains, plantar fasciitis, knee pain, and altered gait mechanics. It provides objective, reproducible measurement of this critical motion in both weight-bearing and non-weight-bearing positions.

Unlike passive measures taken on a treatment table, weight-bearing versions of the test (such as the knee-to-wall lunge test) reflect real-world ankle mobility during functional activities, making them preferred by clinicians for discharge planning, return-to-sport clearance, and treatment outcome tracking.

How to use the ankle dorsiflexion test

The assessment follows a systematic 5-step protocol that clinicians use in the clinical setting with physiotherapy practice management tools to document findings:

1. Patient positioning and stabilization: Position the patient standing facing a wall with one foot placed a few inches away from the wall, keeping the heel flat on the ground and the knee straight. The opposite leg steps back to provide balance and stability without contributing to the test movement.
2. Weight-bearing lunge movement: Instruct the patient to slowly move their knee forward toward the wall without lifting the heel off the ground. The movement is controlled and pain-free, stopping when the knee makes light contact with the wall or when heel lift begins.
3. Measurement recording: Measure the distance from the wall to the patient’s big toe using a tape measure, or simply note whether knee-to-wall contact is achieved. Document findings on measurement tracking software for bilateral comparison and serial tracking.
4. Bilateral testing and comparison: Repeat the procedure on the opposite ankle and record both results. Asymmetry greater than 1 cm between sides warrants further investigation for unilateral restrictions or postural compensations.
5. Silfverskiöld differentiation (optional): To isolate gastrocnemius versus soleus restriction, repeat the weight-bearing test with the patient’s knee bent to 90 degrees. If ROM improves with knee flexion, gastrocnemius tightness is the primary limitation; if ROM remains restricted with knee bent, soleus involvement is likely.

Clinical assessment form templates streamline this protocol by providing checkboxes for test variants, predefined measurement fields, and automated bilateral comparison calculations.

Who is the ankle dorsiflexion test helpful for?

• Physiotherapists and sports medicine clinicians use the test as a foundational screening tool during initial evaluation and discharge planning. The sports medicine software ecosystem integrates this assessment into injury prevention and return-to-sport protocols.
• Podiatrists and foot health specialists incorporate it into biomechanical assessments, particularly when evaluating lower limb overuse injuries, gait dysfunction, or orthotic fitting needs.
• Athletic trainers and strength coaches use the test to identify mobility restrictions that may predispose athletes to lower limb injury. Dorsiflexion limitations have been linked to increased ankle sprain and anterior knee pain risk in jumping and sprinting athletes.
• Occupational therapists working with occupational therapy assessment tools may assess dorsiflexion ROM as part of comprehensive lower limb function evaluation, particularly for patients with mobility restrictions affecting independence in activities of daily living.

Benefits of using the ankle dorsiflexion test

1. Standardized, reproducible measurement. The test provides objective, quantifiable ROM data that clinicians can track over time and compare across patients. Consistency reduces measurement error and improves reliability for outcome documentation.
2. Functional assessment in weight-bearing. Unlike passive ROM measures on a treatment table, the weight-bearing lunge test reflects ankle mobility in the position where most functional activities occur, improving the clinical relevance of findings and treatment decisions.
3. Identifies asymmetry and bilateral comparison. Side-to-side ROM comparison reveals unilateral restrictions that may indicate compensatory patterns, postural misalignment, or previous injury. Documenting bilateral findings guides targeted treatment planning.
4. Guides differential diagnosis. The return-to-running protocol and other functional assessments depend on accurately distinguishing gastrocnemius from soleus limitation – information the Silfverskiöld variant of the test provides. This differentiation informs stretching versus strengthening priorities.
5. Supports treatment planning and monitoring. Serial measurements track intervention response and justify progression to functional activities, making the test a cornerstone of progress documentation.

Open-chain versus closed-chain ankle dorsiflexion testing

The test can be performed in two distinct biomechanical contexts, and the choice affects the ROM values obtained and their clinical interpretation.

Closed-chain testing

Closed-chain testing (weight-bearing lunge and knee-to-wall variants) measures ankle dorsiflexion while the foot remains in contact with the ground. This position creates tibial forward movement over a fixed foot, reflecting how dorsiflexion ROM functions during walking, running, and stance. Closed-chain testing typically yields greater ROM values (10-15 cm knee-to-wall distance is common) because the ankle can dorsiflex more fully when stabilised by ground contact.

Open-chain testing

Open-chain testing involves passive ankle dorsiflexion measurement with the patient lying or sitting, the hip and knee in neutral or flexed positions, and no ground contact. Open-chain methods use a goniometer to measure the angle between the tibia and foot. These measurements are smaller (typically 10-15 degrees of dorsiflexion) and reflect isolated ankle joint mobility independent of lower limb positioning.

Critical difference

Weight-bearing and non-weight-bearing dorsiflexion measurements are not interchangeable. A patient may have normal passive ankle dorsiflexion on a goniometer but limited weight-bearing dorsiflexion due to calf muscle recruitment patterns, proprioceptive limitations, or pain inhibition. Always document which test variant was used and avoid comparing values between measurement methods.

Normative values and interpretation

Research on the knee-to-wall ankle dorsiflexion test establishes normative reference values for adult populations. According to Human Kinetics, the typical distance achieved in the weight-bearing lunge test is 10-15 cm (4-6 inches). Distances less than 10 cm may indicate clinically meaningful dorsiflexion restriction.

Population-specific norms exist for different age groups and activity levels. Young athletes may demonstrate 15+ cm dorsiflexion, while older adults or sedentary populations may average 8-10 cm. Always compare individual test results to age-matched and activity-matched reference values rather than applying a single normative threshold across all patients.

The reliability of the weight-bearing lunge test is well-established. Research cited by Phil Plisky’s assessment framework documents interrater reliability (ICC) of 0.95 (95% CI: 0.92-0.97) for the half-kneeling closed-chain dorsiflexion test, indicating high consistency when trained clinicians administer the test.

When interpreting results, asymmetry between sides and change over time matter as much as absolute values. A 2 cm difference between left and right ankle warrants investigation. Improvement of 3-5 cm over a 4-week treatment period demonstrates meaningful ROM gain.

When ankle dorsiflexion is limited: Common causes and clinical considerations

1. Gastrocnemius tightness is the most common reason for limited weight-bearing ankle dorsiflexion. The two-joint gastrocnemius muscle crosses both the knee and ankle; tightness restricts dorsiflexion most obviously with the knee extended. Calf stretching and eccentric strengthening usually improve ROM within 2-4 weeks of consistent intervention.
2. Soleus restriction creates dorsiflexion limitations that persist even when the knee is flexed (Silfverskiöld positive). Soleus involvement often reflects prolonged immobility, plantarflexor weakness, or chronic lower limb pain patterns. Recovery typically requires longer intervention periods and sport-specific loading.
3. Ankle joint capsular stiffness or post-ankle sprain sequelae may restrict dorsiflexion despite normal calf length. These patients benefit from joint mobilization, proprioceptive training, and ankle injury assessment protocols to determine clearance for return to weight-bearing activities.
4. Proprioceptive or pain-related inhibition can limit weight-bearing dorsiflexion ROM without genuine structural restriction. In these cases, the passive non-weight-bearing ankle dorsiflexion test may show normal ROM, while the weight-bearing test remains limited. Graded exposure to weight-bearing positions often improves functional ROM.

Conclusion

The ankle dorsiflexion test is a fundamental assessment for identifying ankle mobility restrictions and guiding rehabilitation decisions. Whether using the weight-bearing knee-to-wall variant, Silfverskiöld differentiation, or non-weight-bearing goniometric methods, clinicians benefit from standardized documentation and serial tracking. Implementing patient intake software eliminate transcription errors and enable automatic bilateral comparison, turning routine measurements into actionable data for treatment planning and patient outcome tracking.
