What Should You Assess When the Ankle Keeps Giving Way After a Sprain?
The client may describe a very specific moment: walking on uneven ground, stepping off a curb, landing or changing direction and suddenly feeling that the ankle “goes” again. They may hesitate before loading the foot or show a guarded expression even when there is little pain at rest. Recurrent giving way can involve ligament history, ankle motion, fibularis and calf capacity, sensorimotor control and confidence, rather than one weak muscle.
I first recreate the safe task that exposes the instability and decide whether the main limitation is mobility, local tissue capacity, sensorimotor control or a presentation that needs referral. Compare the sprain history, weight-bearing dorsiflexion, ligament-region findings, single-leg balance and a tolerable landing or direction-change task. Major swelling, fracture signs, true locking, progressive foot drop, numbness or marked loss of function changes the plan.
In this article, you will learn how to assess an ankle that keeps giving way, compare ligament, joint and muscular contributors, identify what manual treatment can and cannot change, and re-test the same balance, landing or change-of-direction task.

1. Clinical Problem & Differential: Ankle Keeps Giving Way
Clarify the original injury, number of recurrent sprains, swelling, locking, catching, surface, footwear and the exact movement that causes giving way. Inability to bear weight after trauma, marked bony tenderness, deformity, progressive foot drop, persistent numbness, major swelling or suspected fracture requires medical assessment.
Giving way may mean a sudden inversion episode, a feeling of uncertainty or a loss of balance without another sprain. I ask which actually happened and during what task. This distinction keeps ligament history, available motion and movement control in the examination without assuming that all instability is a tight fibularis muscle or a weak ankle that needs the same exercise.
2. Muscle / Joint / Nerve Comparison: Fibularis & Tibialis + Ankle Joint
Fibularis longus and brevis, tibialis anterior and posterior and the calf contribute to ankle control, but tenderness or weakness alone cannot establish the source. Compare the talocrural and subtalar joints, ATFL/CFL region, weight-bearing dorsiflexion and side-to-side capacity. Screen the common fibular nerve and lumbar source when sensory change, weakness or symptom distribution suggests neural involvement.
Fibularis longus and brevis contribute to eversion, while tibialis anterior contributes to dorsiflexion and inversion. Their actions help interpret foot control but do not diagnose ligament integrity. The anterior talofibular ligament lies anterior to the lateral malleolus, and the calcaneofibular ligament runs toward the calcaneus. Those ligament regions are distinct from the fibular muscle bellies and the tendons passing behind the malleolus.
3. Differential Assessment: Chronic Ankle Instability + Balance
- Reproduce the comparable balance, landing or direction-change task safely.
- Record recurrent-sprain and giving-way history and consider the Cumberland Ankle Instability Tool (CAIT) or Foot and Ankle Ability Measure (FAAM).
- Measure weight-bearing lunge dorsiflexion.
- Use ATFL palpation and anterior drawer, with talar tilt when appropriate; do not interpret one test in isolation.
- Compare single-leg balance and Star Excursion Balance Test (SEBT) or Y-Balance performance.
- Add hop or change-of-direction testing only when load tolerance permits.
- Re-test the identical task after one targeted intervention.
History plus a compatible test cluster is more useful than diagnosing instability from one painful structure.
I also compare passive end feel and comfortable talocrural distraction or glide with the active balance task. If ankle motion improves but the client still loses control, mobility was only part of the problem; the fibularis response, foot loading and proprioceptive strategy still need to be tested under movement.
4. Treatment Scope & Symptom Re-Test: Lateral Ligament History
Remedial treatment may address symptom-relevant calf, fibularis, tibialis and crural-fascial tissues and comfortable ankle mobility. It cannot repair a torn ligament or replace progressive balance and strength rehabilitation. If ankle motion becomes easier but giving way persists, I shift attention to the permitted balance and strength work instead of repeating the same release. Available motion and control under load are separate findings. Repeat the same task with the same surface, stance and speed, recording symptoms, control and confidence. Recurrent major instability, locking, suspected tendon subluxation or neurological loss warrants referral.
I keep a relevant lateral-calf contact over the identified muscle belly, with the foot supported, rather than pressing behind a snapping lateral malleolus. A comfortable low-velocity, small-amplitude non-thrust ankle input is an option only when examination and training support it. If available motion improves but balance still fails, I move to the permitted control task instead of repeating the mobilisation.
5. Re-Test: Single-leg balance with the same surface and support
Repeat the same supported balance task with the same surface, footwear, stance and duration. Record loss of balance, giving-way sensation and confidence separately from ankle range. More dorsiflexion does not demonstrate restored control.
If dorsiflexion improves but balance remains unreliable, the next activity should address control rather than seek still more range. Within the rehabilitation plan, a supported single-leg stance or controlled step can provide a manageable starting task; record the support, surface and duration before changing one demand. Balance training improved selected functional and balance outcomes in a small randomized trial, but it did not establish that one easier test clears an ankle for sport. Follow whether ordinary walking, uneven ground and later direction changes become more dependable, including any further giving-way episodes. Recurrent major instability, locking, suspected tendon subluxation or new weakness requires reassessment rather than a harder balance drill.
