Lateral ankle sprains are commonly seen in the sports medicine arena. Traditional treatment of this particular injury is initial symptom management from a Western perspective. I will review an integrated Western practice that can utilize Eastern strategies and philosophies.This combination will suggest more detailed evaluation and lead to more optimal long-term recovery outcomes.
In sports medicine, most lateral ankle instability results from physiological (mechanical and functional) instability. It is necessary to compare normal ankle mechanics to abnormal mechanics, sequelae to these sprains, and rate dysfunction of the surrounding tissues involved. The basic treatment protocol focuses on accurately assessing joint function, increasing range of motion, and protecting the healing tissues where there may be excessive movement.
|Mechanical/Functional Chronic Ankle Instability Paradigm|

Mechanical and function instability creates recurrent ankle sprains. Lateral ankle sprains, usually due to excessive inversion and supination, injure the anterior talofibular and calcaneofibular ligaments and the subtalor and tibiofibular articulations. Once a ligament is lengthened, over time, if the tendon structures are not stabilized, residual dysfunction (hypermobility) may become long-lasting. Typical signs and symptoms include inflammation, pain, decreased range of motion and swelling. Protocol treatments focus on restoring normal accessory joint motion and reducing subluxations, while simultaneously protecting damaged ligaments from external and internal stresses that may compromise the healing process. Thus, RICE (rest, ice, compression, elevation) is the key concept here so as to manage the edema, which can last up to three weeks.
Focus then moves to restoring ligament stability by correcting subluxations and treating accessory motion restriction using joint mobilization. Exercises (closed and open chain) are then implemented to restore range of motion. Resistance is then added to restore strength. Once strength is restored, and we have established normal gait with normal joint mobility, the focus shifts to neuromuscular control in order to maximize dynamic and reflexive stability of the surrounding tissues.
According to traditional Chinese medicine (TCM), pre-existing factors that contribute to ankle sprains include the consuming of the qi and blood (creating Liver and Kidney deficiency); accumulation of dampness; invasion of external pathogens (wind, cold, damp); and, of course, blood stagnation.
Injury mechanisms also play a big part in differentiation among pre-existing factors that create an ankle sprain (chronic condition) versus direct or indirect trauma (acute condition). According to TCM, acute versus chronic represents external versus internal origins of the mechanism of injury. Chronic represents internal pre-existing problems that allow the external pathogens to invade more easily, disrupting the circulation of qi and blood in that specific location.
The concept of TCM is to maintain the flow of qi and blood circulation throughout the body. By maintaining this circulation of qi/blood, the physiological manifestation of injuries and pain are non-existent. However, if the qi/blood becomes stagnant, the flow within the channels around the affected joint becomes blocked and impaired, creating pain along the affected joint. The main physiological manifestation includes pain that is stabbing and fixed for blood stagnation, and wandering and distended pain for qi stagnation.
According to TCM, the Liver supports the tendons by nourishing them through Liver blood, while the Kidney nourishes the bones. Through years of overstraining, working long hours (standing all the time), constitutional weakness and/or prolonged illness, the qi and blood deplete and/or consume specifically the qi and blood of the Liver and Kidney. In either case, the lack of nourishment of both the tendons and bones gives rise to ankle-joint injuries. Once again, age is a factor. As we get older, the Liver and Kidney functions decline, and the Kidney jing and Liver blood are unable to nourish the tendons and bones sufficiently.

Pulse = superficial, forceful
Severe pain, worse with cold, aversion to cold, cold extremities, decrease ROM, pain better with application of warmth

Pulse = slow, tight
Heavy sensation, painful, swelling, fixed location, decreases ROM, worse in rainy and damp weather changes
Tongue = greasy, white coating
Pulse = slow, soft, slippery
Local burning sensation, redness, swelling, pain, worse with touch, decreased ROM
Tongue = yellow, greasy coat
Pulse = slippery, rapid
Redness, swelling, pain, worse with touch, decreased ROM, aversion to cold, general body aches, headache, fever

Wind, cold and damp pathogens are able to invade through the joints because that is where qi enters and exits. Wind characteristics tend to be always moving and changing, and present with pain moving medially to laterally on the ankle. Cold characteristics create qi and blood stagnation due to the contracting nature within the channels and tendons, and thus present with severe ankle pain. Damp characteristics create obstructions within the channels due to the accumulation, creating heaviness that leads to stagnation, and thus present with fixed ankle pain, swelling with a heavy sensation, and possible numbness.
Pre-existing conditions that allow these external pathogens to invade include yang and/or yin deficiency. Heat is another factor that can be a result of wind/cold/damp invasion. If an athlete has had long-term wind/cold/damp invasion and has accumulated sitting stagnation, this will generate heat. This also disrupts the qi and blood circulation in the channels causing accumulation, which progresses to stagnation in the channels around the affected joint. In TCM, this is referred to as damp heat. Heat presents with redness, feelings of heat around the joint and swelling.
Athletes are exposed to environmental changes that result in possible internal deficiencies. Another factor that predisposes athletes to this condition is diet. Athletes, especially those in high school and college, tend to eat on the run, and are constantly eating fast foods. Fatty, greasy foods, sweets and alcohol impair the Spleen's function. Internally, this gives rise to damp heat accumulation over time. This accumulation moves downward into the lower extremities and blocks the channels, giving rise to ankle injuries and pain.
Lateral ankle sprains are extremely common within the sports medicine arena, yet treatments using only the Western protocol are inadequate in the prevention of recurrent sprains. Understanding and appreciating the pathomechanics, anatomy and mechanics of the ankle complex, one should integrate and appreciate another level within treating lateral ankle sprains, by using licensed acupuncturists and the concept of Oriental medicine within the treatment strategy. The clinical management should include not only the symptoms of both mechanical and functional instabilities, but also address the integration of TCM, emphasizing the prevention and reducing the risk of chronic lateral ankle sprains.
