Joints and bones
Ankles fail at balance, not strength
After a sprain, the thing that most often does not come back on its own is the sense of where the joint is, and that is trainable.
What it is
Most ankle problems start with a lateral sprain, where the ankle rolls outward and the ligaments on the outside are overstretched. What often persists afterwards is not ligament damage but chronic ankle instability: a combination of the ankle giving way, feeling unreliable, and repeated sprains. The underlying deficit is usually in proprioception and neuromuscular control, meaning the feedback about where the joint is and the speed at which muscles respond to it, rather than in raw strength.
How it behaves day to day
Repeated rolls on uneven ground, a feeling that the ankle cannot be trusted, and reduced confidence on stairs, kerbs and in the dark. Swelling and pain may have long settled while the unreliability remains, which is the pattern that tells you it is a control problem.
What tends to feed it
- Uneven ground and kerbs, particularly when tired or distracted
- Returning to sport before balance and control have been retrained
- Relying on a brace without doing the balance work alongside it
- Repeated minor rolls that are never rehabilitated
What the research recommends
The reference document is the lateral ankle ligament sprains guideline, revised in 2021 and published in JOSPT by the Academy of Orthopaedic Physical Therapy. Its recommendation for chronic ankle instability is specific: clinicians should prescribe proprioceptive and neuromuscular therapeutic exercise to improve dynamic postural stability and the person's own sense of stability during function, supported by strong to moderate evidence, alongside graded joint mobilisation. For a first sprain, it recommends prophylactic bracing together with proprioceptive and balance-focused exercise to reduce the risk of the next one. Ongoing balance and neuromuscular control programmes are strongly recommended to prevent chronic instability developing in the first place.

Proprioceptive and neuromuscular therapeutic exercise is recommended for chronic ankle instability, with balance-focused programmes strongly recommended to prevent it developing after a first sprain.

Where ankle and heel symptoms travel together, calf stretching and graded loading carry strong evidence.
Where Vinys is different
- Balance work is treated as training rather than as risk. An app that removes every balance challenge from someone with an unreliable ankle is removing the intervention.
- The balance work is supported, so the challenge is real but there is always something to hold. That is how it stays trainable outside a clinic.
- Calf and foot strength are built alongside the balance work rather than instead of it, since both appear in the guideline.
- Sessions adapt to the day, which matters because a tired ankle is exactly when control is worst and caution is warranted.
- Where yoga meets physiotherapy: standing balance work is native to one and prescribed by the other.
A short session to try
- 1
Tree pose, lift and lower · 5 each side, near a wall
Dynamic single-leg balance, which is the proprioceptive and neuromuscular work the guideline names.
- 2
Heel raise · 10 to 12 slow reps
Calf and ankle strength, the base that balance work is built on.
- 3
Heel raise with a block between the heels · 8 to 10 reps
Adds a control demand to the heel raise, so it trains more than raw strength.
- 4
Downward dog, hands on wall · 30 to 45 seconds
Calf length at partial load, which affects how the ankle moves under you.
- 5
Toe squat · 20 to 30 seconds
Opens the sole of the foot and toes, which are part of how the foot reads the ground.
Do the balance work with a wall or chair within reach. The point is to challenge the ankle with support available, not to test whether you fall.
Movements often used for this
Balance · 30 to 60 seconds
Tree Pose: Lift & Lower
A gentle first step toward standing on one leg: you simply shift your weight and lift the other foot a little, teaching your body single-leg confidence without a long balance hold.
Ankles and calves · 30–60 seconds of slow repetitions
Heel raise
The calf is the engine of every step, and it is trained by going slowly down, not quickly up.
Stability / Core · 30 to 60 seconds
Heel Raise: Block Between Heels
Strengthens your calf muscles eccentrically and concentrically, building the ankle power and stability essential for walking, running, and preventing falls.
Upper Limb Weight Bearing · 60 to 90 seconds
Downward Dog: Hands on Wall
Hands on the wall create a gentler angle that reduces load on your spine and shoulders, making the decompressive benefits of this pose accessible for almost everyone.
Hip Mobility · 60 to 120 seconds
Toe Squat
Opens the sole of your foot and toe joints, improving intrinsic foot mobility and helping to relieve plantar tension: beneficial for foot health and overall standing comfort.
Upper Limb Weight Bearing · 60 to 90 seconds
Downward Dog: Chair Supported
The most accessible version: a chair supports your hands, removing deep flexion demands and making this stretch gentle enough for sensitive knees, ankles, and shoulders.
Stability / Core · 30 to 60 seconds
Short Foot: Arch Lift
A small, precise exercise that wakes up the muscles inside your foot, building the arch support that steadies your ankle with every step.
Stability / Core · 30 to 60 seconds
Posterior Tibialis Strengthening
Strengthens the muscles that support your arch and inner ankle, improving foot stability and reducing strain on structures that often contribute to ankle and foot pain.
Restorative · 240 to 300 seconds
Tabletop Full-Body Reset
A quadruped (hands-and-knees) reset combining gentle spinal movement with graded shoulder and thoracic mobility: good preparation for floor-based practice.
Transitional · 240 to 360 seconds
Surya A: Chair Supported
The most accessible sun salutation: every position adapted to a chair, making this beautiful flowing movement practice available to everyone regardless of mobility level.
Transitional · 300 to 420 seconds
Surya B: Chair Supported
The most accessible Surya B: all positions adapted to seated chair work, bringing the benefits of this extended flowing sequence to everyone.
Balance · 30 to 60 seconds
Tree Pose: Holding Chair
The chair provides reliable support while you develop your balance, letting you focus on building single-leg stability at your own pace.
These are movements the clinical library marks as especially beneficial for this movement pattern, with anything it flags as a caution for the same pattern removed. A pattern is not a diagnosis, and your own session is built from your answers on the day.
Common questions
Why balance rather than strength?
The persistent deficit after a sprain is usually proprioception and neuromuscular control, and the 2021 guideline recommends proprioceptive and neuromuscular exercise specifically for chronic ankle instability.
Do I need a brace?
The guideline recommends prophylactic bracing after a first sprain together with balance-focused exercise. Together is the operative word; a brace alone does not retrain control.
My ankle does not hurt, it just feels unreliable. Is that a thing?
Yes. That is the pattern chronic ankle instability describes, and it is what the proprioceptive work is aimed at.
Get it assessed if you could not weight-bear after the injury, if there is bony tenderness, significant swelling or bruising, or if the ankle keeps giving way despite rehabilitation.
