Ankle rehabilitation exercises after a sprain

Ankle sprains: the most common and most underestimated injury

Ankle sprains account for roughly one in every five sports injuries. They are the most common musculoskeletal injury in the general population. Yet the majority of people who sprain their ankle never complete a full rehabilitation programme. Many assume that once the pain fades, the ankle is healed. It is not. Without proper rehab, the re-injury rate reaches 70% within the first year after the initial sprain.

A sprain is a ligament injury. Ligaments are bands of connective tissue that connect bones and stabilise joints. When the foot rolls inward suddenly, the lateral ligaments on the outside of the ankle stretch beyond their capacity. Depending on the force, the fibres may overstretch (mild sprain, grade 1), partially tear (moderate sprain, grade 2), or rupture completely (severe sprain, grade 3).

Pain, swelling and difficulty bearing weight are immediate. But what you cannot see matters just as much: the sensory receptors embedded in the ligaments, called mechanoreceptors, are damaged. These receptors tell the brain where the ankle is positioned in space. When they are impaired, the ankle loses its ability to react quickly to changes in terrain. That is why proprioceptive rehabilitation forms the backbone of sprain treatment.

The first few days: managing the acute phase

The first 48 to 72 hours after a sprain focus on managing inflammation and pain. The PEACE & LOVE protocol has replaced the old RICE approach (rest, ice, compression, elevation) in current guidelines.

PEACE stands for Protection, Elevation, Avoid anti-inflammatories, Compression and Education. During the first days, protect the ankle by avoiding painful movements. Elevate the leg to encourage drainage. Avoid non-steroidal anti-inflammatory drugs (ibuprofen) for the first 48 hours, because early inflammation plays a role in tissue repair. Apply a compressive bandage. And understand that prolonged complete rest is harmful.

LOVE stands for Load, Optimism, Vascularisation and Exercise. As soon as pain allows, start putting weight on the foot. Early weight bearing stimulates ligament healing and prevents muscle wasting. Walking with crutches is a good compromise in the first days: put the foot down, but offload some of the weight.

Ice application remains useful for comfort. Apply it for 15 to 20 minutes, 3 to 4 times a day, with a cloth between the skin and the ice. It reduces pain and limits excessive swelling. Do not leave it on longer: prolonged cold slows circulation and may delay healing.

Weeks 1 and 2: restoring mobility

Once the acute phase has passed, the ankle is often stiff. Swelling lingers. Dorsiflexion (pulling the toes toward the shin) is usually the first range of motion to become restricted, and it is also one of the most important for walking and climbing stairs.

Foot alphabets. Seated, with the leg crossed or the foot hanging off the edge, trace the letters of the alphabet with your big toe. Complete the alphabet twice. This exercise moves the ankle in every direction in a progressive, controlled way.

Weight-bearing dorsiflexion stretch. Stand facing a wall, one foot forward, knee slightly bent. Push the knee toward the wall while keeping the heel on the ground. Move the foot forward gradually until you find the maximum distance where the heel still stays down. Hold 15 seconds. 10 repetitions. This exercise is the gold standard for restoring dorsiflexion. A dorsiflexion deficit alters walking mechanics and predisposes to re-injury.

Fibula mobilisation. Seated, cross the injured ankle over the opposite knee. With both hands, grasp the lateral malleolus (the bony bump on the outside of the ankle) and gently glide it forward and backward. 30 seconds. Repeat 5 times. After a sprain, the fibula often becomes stuck in an anterior position, which limits dorsiflexion. This mobilisation helps reposition it.

Contrast bath (optional). Alternate between warm water immersion (38 to 40 degrees Celsius, 3 minutes) and cold water (10 to 15 degrees, 1 minute) for 15 minutes, finishing with cold. This protocol boosts circulation and helps clear residual swelling.

Weeks 3 and 4: muscular strengthening

The peroneal muscles (on the outer side of the lower leg) are the ankle's first line of defence against sprains. When the foot starts rolling inward, the peroneals fire reflexively to pull it back to a neutral position. After a sprain, that reflex is impaired. Strengthening combined with proprioception restores it.

Eversion against resistance. Seated, with an elastic band looped around the forefoot and the other end anchored to a table leg on the inner side. Push the foot outward against the band's resistance. Control the return. 3 sets of 15 repetitions. This targets the peroneal muscles directly.

Inversion against resistance. Same setup, but the band is anchored on the outer side. Pull the foot inward. 3 sets of 15 repetitions. This strengthens the tibialis posterior, a muscle that supports the arch and stabilises the inner ankle.

Plantarflexion against resistance. Seated, elastic band looped around the forefoot, the other end held in both hands. Push the foot downward as if pressing a gas pedal. 3 sets of 15 repetitions. The calf is the most powerful muscle group at the ankle. Its strength is decisive for propulsion during walking and running.

Calf raises, bilateral then unilateral. Standing with feet flat, rise onto your toes. Hold 2 seconds. Lower over 3 seconds. 3 sets of 15 repetitions on both feet. When that is pain-free, progress to single-leg raises. Aim for 3 sets of 12. This strengthens the calf in a functional position and begins to challenge balance.

Weeks 3 to 6: proprioception, the heart of rehabilitation

Proprioception is the body's ability to sense its position in space without relying on vision. It depends on information sent to the brain by receptors in ligaments, tendons, muscles and skin. After a sprain, these receptors are damaged. The brain receives less accurate, slower signals. The ankle no longer reacts fast enough to disturbances. The result: it rolls again.

Proprioceptive training places the ankle in progressively unstable, controlled situations. The brain learns to compensate for lost receptors by using other information sources and by processing signals faster.

Single-leg stance, eyes open. Stand on the injured leg. Keep the knee very slightly bent. Hold your balance for 30 seconds. If it feels easy, close your eyes. Removing vision forces the proprioceptive system to work harder. Aim for 3 sets of 30 seconds eyes open, then eyes closed.

Single-leg stance on an unstable surface. Repeat the previous exercise on a cushion, a folded pillow or a wobble board. The unstable surface multiplies disturbances and forces the ankle to correct continuously. 3 sets of 30 seconds. Add eyes closed when the eyes-open version feels stable.

Throw and catch on one leg. Standing on one leg, throw a ball against a wall and catch it. The need to coordinate the upper body with lower-body balance challenges the ankle in a functional way. 3 sets of 20 throws.

Clock reaches. Standing on the injured leg, imagine you are at the centre of a clock face. With the free foot, tap the floor at 12 o'clock (front), 3 o'clock (side), 6 o'clock (behind), 9 o'clock (other side). Return to the centre between each position. 3 full rounds. This drill combines balance, range and control in every direction.

Weeks 6 to 8: gradual return to activity

Returning to sport after a sprain should not happen overnight. Ligaments heal slowly. Newly formed collagen takes several months to regain its original tensile strength. Going back too soon means loading fragile tissue and risking a new injury.

Brisk walking, then light jogging. Start with 20 minutes of brisk walking on flat ground. If the ankle does not swell and does not hurt the next day, try a slow jog the day after. Alternate 2 minutes of running and 1 minute of walking for 20 minutes. Gradually increase the running intervals. No pain during, no swelling after: you can keep progressing.

Running with direction changes. On a flat surface, place markers on the ground (cones, bottles). Run in a slalom pattern. Start slowly, then pick up speed. This type of running loads the ankle in the lateral plane, the very direction of the sprain. It is a necessary step before returning to team sports or racquet sports.

Jumping and landing. Jump on the spot, first on both feet, then on one. Jump forward, backward, sideways. Land in a controlled manner, knee bent, without letting the ankle roll inward. 3 sets of 10 jumps in each direction. Plyometrics is the final stage of rehabilitation. If the ankle tolerates jumps and landings without pain, it is ready for sport.

Should you wear an ankle brace?

Wearing a semi-rigid ankle brace is recommended for the 6 to 8 weeks following a sprain, particularly during physical activity. Studies show it reduces re-injury risk by close to 50% during this period. It does not replace rehabilitation, but it provides mechanical support while the ligaments heal and the muscles regain their stabilising role.

In the long run, a brace becomes a crutch. Muscles stop working fully when they are permanently supported. The goal is to wean off the brace gradually: first in daily life, then during light training sessions, and finally in competition.

Taping (adhesive bandaging) is an occasional alternative, but it loosens within 20 to 30 minutes of activity and then offers minimal protection. A brace is more reliable for sustained wear.

When to see a professional

Certain signs should prompt medical attention after a sprain. If you cannot bear weight at all 48 hours after the injury, an X-ray is needed to rule out a fracture. If the ankle remains very swollen and painful after a week despite following the PEACE protocol, seek medical advice. If you feel clicking, locking or giving way (the ankle buckling), further assessment is warranted.

After a severe sprain (grade 3), physiotherapy follow-up is strongly recommended. A physiotherapist tailors exercises to your situation, corrects your technique and monitors progression. They also have access to manual therapy techniques and modalities (ultrasound, compression therapy) that accelerate swelling resolution and mobility recovery.

Preventing re-injury in the long term

The best treatment for an ankle sprain is never having another one. A few habits protect the ankle for the long haul.

Maintain a proprioception programme even after recovery. Two 10-minute sessions per week are enough. Single-leg standing while brushing your teeth, balancing on a cushion while watching television: weave these exercises into daily life so they become automatic.

Strengthen the peroneals and calf regularly. Two sets of calf raises and eversions with a band, three times a week, maintain the required strength.

Warm up before every physical activity. Ankle circles, calf raises and a few minutes of brisk walking prepare the joint for the demands ahead.

Choose footwear suited to your activity. Trail shoes with solid ankle support for rough terrain. Indoor shoes with a grippy sole for court sports. Worn-out shoes lose their cushioning and support: replace them regularly.

The ankle is a robust joint when properly prepared. Repeated sprains are not inevitable. With complete rehabilitation and sound prevention habits, you can build a stable, confident ankle capable of carrying you across any terrain.
