A sprained ankle is one of the most common musculoskeletal injuries. It can happen during sports, exercise, walking on an uneven surface, or simply stepping awkwardly. Although many mild ankle sprains improve with appropriate care and time, pain, swelling, stiffness, and reduced movement can sometimes continue for weeks.
At Phnom Penh Acupuncture Physiotherapy Center (PAPC), treatment for a sprained ankle may include a combination of massage, therapeutic ultrasound, acupuncture, and rehabilitation exercises, depending on the individual’s condition and stage of recovery.
The goal is not simply to reduce pain. A good rehabilitation program should also help restore ankle movement, muscle function, balance, strength, and confidence when walking or returning to sports.
An ankle sprain occurs when the ligaments supporting the ankle are stretched beyond their normal range or partially or completely torn.
The ankle has several important ligaments, with the ligaments on the outside of the ankle being particularly vulnerable when the foot rolls inward.
Common symptoms include:
The severity of an ankle sprain can vary. A mild sprain may involve overstretched ligaments, while a more significant injury may involve a partial or complete ligament tear.
It is common for an ankle to remain stiff or uncomfortable after the initial injury.
After a sprain, swelling and inflammation can affect normal ankle movement. The surrounding muscles may also become tense or weaker because the person naturally avoids putting weight on the injured side.
In some cases, the ankle may feel unstable even after the pain has decreased.
This is why rehabilitation is important. Returning to normal activity too quickly without restoring strength and balance may increase the risk of another ankle injury.
Massage can be incorporated into ankle rehabilitation when appropriate.
The techniques used should depend on the injury stage. Directly applying strong pressure to a recently injured or highly swollen area may not be appropriate.
Once the acute stage has passed and the tissues are suitable for manual treatment, gentle massage may be used around the ankle and lower leg.
Potential goals of massage include:
Massage is generally best used as part of a broader rehabilitation program rather than as the only treatment.
Therapeutic ultrasound is another modality that may be used during physiotherapy.
Ultrasound therapy uses high-frequency sound waves applied through the skin with a treatment head and coupling gel. Depending on the treatment parameters, ultrasound may be used to support soft-tissue treatment and rehabilitation.
At PAPC, ultrasound treatment can be selected according to the individual’s symptoms, injury stage, and treatment goals.
It may be combined with manual therapy and therapeutic exercise rather than used as a standalone treatment.
A physiotherapist should determine whether ultrasound is appropriate for the particular injury.
Acupuncture may also be considered as part of a comprehensive approach to ankle pain.
During acupuncture treatment, very fine needles are inserted at selected points. The treatment may focus on areas around the ankle and, depending on the treatment approach, other points that may help address pain and muscle tension.
For some people, acupuncture may help with pain management and make movement or rehabilitation exercises more comfortable.
However, acupuncture should not replace appropriate assessment, rehabilitation, or medical evaluation when a significant injury is suspected.
Every ankle injury is different.
One person may mainly have swelling and stiffness, while another may experience muscle tightness, reduced ankle movement, weakness, or instability.
Combining different treatment approaches allows rehabilitation to be adjusted according to the individual’s needs.
For example, a treatment session may include:
Assessment → Manual therapy or massage → Ultrasound when appropriate → Acupuncture when appropriate → Mobility exercises → Strength and balance training
The exact combination depends on the person’s symptoms and stage of recovery.
Passive treatments can help manage symptoms, but restoring ankle function usually requires movement and exercise.
As pain and swelling improve, rehabilitation may gradually introduce exercises such as:
Gentle ankle movements can help restore mobility.
Examples include controlled ankle circles or moving the foot up and down within a comfortable range.
The calf muscles play an important role in walking, running, jumping, and maintaining ankle control.
Calf raises may be introduced progressively when appropriate.
Resistance exercises can strengthen muscles that support the ankle.
Exercises may include controlled ankle movements against resistance.
Balance rehabilitation is particularly important after an ankle sprain.
Simple exercises such as standing on one leg may be introduced and gradually progressed.
More advanced rehabilitation can include unstable surfaces, reaching exercises, or sport-specific movements.
Athletes often want to return to sport as quickly as possible. However, pain relief does not necessarily mean that the ankle has completely recovered.
Before returning to running, jumping, or competitive sports, it is important to consider:
A gradual return is generally preferable to immediately returning to full-intensity activity.
Not every ankle injury is a simple sprain.
Medical assessment may be appropriate if you have severe pain, significant swelling, obvious deformity, inability to bear weight, severe bruising, numbness, or symptoms that are not improving.
A healthcare professional can determine whether further assessment or imaging is necessary.
If symptoms continue for an extended period or the ankle repeatedly gives way, a physiotherapy assessment can also help identify movement, strength, balance, or stability problems.
At Phnom Penh Acupuncture Physiotherapy Center, treatment can be tailored to your symptoms and recovery stage.
Depending on your condition, your treatment program may include:
Physiotherapy
Assessment of movement, strength, mobility, and functional limitations.
Massage and manual therapy
Appropriate soft-tissue techniques to support mobility and reduce muscle tension.
Ultrasound therapy
Used when clinically appropriate as part of a broader physiotherapy program.
Acupuncture
May be incorporated to support pain management and comfortable movement.
Therapeutic exercise
Progressive exercises designed to improve ankle mobility, strength, balance, and function.
The objective is to help you move more comfortably and safely while reducing the likelihood of persistent weakness or instability.
Massage may help reduce surrounding muscle tension and improve soft-tissue mobility when used at an appropriate stage of recovery. Strong massage directly over a fresh injury may not be suitable.
Therapeutic ultrasound may be used as part of physiotherapy for selected patients. Its suitability depends on the injury, symptoms, and treatment stage.
Acupuncture may be used as part of a pain-management and rehabilitation program. It should complement, rather than replace, appropriate assessment and rehabilitation.
Recovery time varies according to the severity of the injury and the individual’s activity level. Mild sprains may improve relatively quickly, while more significant injuries can take considerably longer.
Appropriate rehabilitation exercises are an important part of recovery, but the exercises should match the injury stage. Starting with gentle movement and gradually progressing to strengthening and balance exercises is generally more appropriate than immediately returning to high-impact activity.
A sprained ankle can seem like a minor injury, but incomplete rehabilitation can sometimes leave the ankle stiff, weak, or unstable.
Massage, ultrasound therapy, acupuncture, and therapeutic exercise can be combined according to the individual’s condition and rehabilitation goals.
The most important part of treatment is finding the right approach for your particular injury and progressing rehabilitation safely.
If you have ongoing ankle pain, swelling, stiffness, or instability after an ankle injury, consider having your ankle assessed by a qualified healthcare professional or physiotherapist.
