Chronic Ankle Instability

What is Chronic Ankle Instability?

Chronic ankle instability is a condition characterized by a recurring sensation of the ankle “giving way” or feeling unstable, particularly on the outer side. This condition often develops after an initial ankle sprain that has not healed adequately or has not been fully rehabilitated. It can affect anyone, from athletes to individuals with a more sedentary lifestyle.

Main Causes

The primary cause of chronic ankle instability is an incompletely healed lateral ankle sprain. When the ligaments on the outside of the ankle are stretched or torn during a sprain, they can lose their ability to provide adequate support to the joint if not properly rehabilitated.

Contributing factors include:

Inadequate Rehabilitation: Failure to complete a full physical therapy program after an initial sprain can lead to persistent weakness and poor proprioception (the body’s sense of its position in space).
Repetitive Injuries: Each subsequent ankle sprain can further damage and weaken the ligaments, perpetuating the cycle of instability.
Muscle Weakness: Weakness in the muscles surrounding the ankle, particularly the peroneal muscles on the outside of the lower leg, can contribute to instability.
Impaired Proprioception: Damage to the nerves in the ankle ligaments can impair the body’s ability to sense the position of the ankle joint, leading to delayed or inaccurate muscle responses to prevent further sprains.
Anatomical Factors: Certain foot structures, such as high arches, can predispose individuals to ankle sprains and subsequent instability.

Signs & Symptoms

Recurrent Ankle Sprains: The most prominent feature is a tendency to experience repeated ankle sprains, often with minimal provocation.

Feeling of Instability: A persistent feeling that the ankle is wobbly, weak, or untrustworthy, especially on uneven surfaces or during physical activity.

“Giving Way” Sensation: A sudden feeling of the ankle buckling or turning, which can occur during activities or even while standing still.

Persistent Symptoms: Ongoing discomfort, swelling, pain, and tenderness in the ankle are common.

Decreased Function: Individuals may experience a limited range of motion, weakness in the ankle, and difficulty with activities that require balance and stability.

Preventive Measures & Lifestyle Modifications

The most critical step in preventing chronic instability is to fully rehabilitate after an initial ankle sprain. Allow adequate time for the ligaments to heal. Returning to activities too soon is a primary cause of re-injury. Work with a physical therapist to restore your ankle’s strength, flexibility, and range of motion.

Lifestyle Modifications for Management

1. Footwear Choices: The shoes you wear daily play a significant role in ankle stability:

Supportive Shoes: Opt for shoes with good arch support, a firm heel counter, and a wide base of support.
High-Tops: For added stability, especially during physical activity, high-top shoes can provide extra support around the ankle joint.
Avoid Unstable Footwear: Minimize the use of high heels, flip-flops, and backless shoes, as they offer little to no ankle support.

2. Activity Modification: While staying active is important, you may need to adjust your activities:

Choose Low-Impact Exercises: Activities like swimming, cycling, and using an elliptical machine are excellent for cardiovascular health without putting excessive strain on your ankles.
Be Mindful of Surfaces: Pay close attention when walking or running on uneven terrain.
Warm-Up Properly: Always warm up before any physical activity to prepare your muscles and joints for movement.

3. Weight Management: Maintaining a healthy weight can significantly reduce the load on your ankle joints, decreasing the risk of injury.

4. Listen to Your Body: Pay attention to any pain, swelling, or feelings of instability. Pushing through these symptoms can lead to further injury. Rest when you need to and consult a healthcare professional if symptoms persist.

5. Ergonomics and Awareness: Be mindful of your ankle’s position during daily activities. Simple adjustments, like ensuring your feet are well-supported when sitting for long periods, can contribute to overall ankle health.

Useful herbs

Ashwagandha (Withania somnifera): Known for its rejuvenating and strengthening properties, Ashwagandha is a powerful adaptogen that helps the body cope with physical stress. It aids in strengthening the muscles and ligaments around the ankle, reducing inflammation, and promoting tissue repair.

Guggulu (Commiphora wightii): Guggulu is a potent anti-inflammatory herb that is widely used in Ayurveda to treat joint disorders. It helps in reducing pain, swelling, and stiffness in the ankle joint. Formulations like Yogaraj Guggulu and Kaishore Guggulu are often recommended.

Shallaki (Boswellia serrata): Also known as Indian Frankincense, Shallaki is highly effective in reducing joint inflammation and pain. It improves blood circulation to the joints, which is essential for healing damaged ligaments.

Bala (Sida cordifolia): The name “Bala” itself means strength. This herb is revered in Ayurveda for its ability to strengthen the neuromuscular system. It nourishes the muscles and ligaments, enhancing their resilience and stability.

Hadjod (Cissus quadrangularis): Literally translating to “bone-setter,” Hadjod is renowned for its ability to heal fractures and strengthen connective tissues. It is beneficial for improving ligament strength and promoting the overall health of the ankle joint.

Rasna (Pluchea lanceolata): Rasna is a valuable herb for managing Vata-related disorders. It has anti-inflammatory and analgesic properties that help in relieving pain and discomfort associated with chronic ankle instability.
