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 would like to review an integrated Western practice that can utilize Eastern strategies and philosophies.This combination will suggest more detailed evaluation and will 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, sequela to these sprains, and rate dysfunction of the surrounding tissues involved. The basic treatment protocol focuses on accurately assessing of joint function, increasing range of motion, and protecting the healing tissues where there may by excessive movement.
Mechanical/Functional Chronic Ankle Instability Paradigm:
- Mechanical – anatomic changes resulting from initial ankle sprain.
- Degenerative changes – repetitive bouts of ankle instability or time.
- Pathological laxity – ankle ends up in vulnerable positions during functional activities (talocrural and subtalar joints).
- Arthrokinematic restrictions – excessive range of motion or decreased ROM.
- Synovial changes - impinged or hypertrophied synovial tissue between ankle complex bones.
- Impaired postural control – balance of synergistic muscle tissues.
- Impaired neuromuscular function – muscular recruitment patterns diminished.
- Impaired proprioception – synergetic ability of nerve conduction velocity diminished.
- Strength deficits – decreased strength of the surrounding muscle tissues.
- Mechanical and function instability creates recurrent ankle sprains.
Lateral ankle sprains, usually due to excessive inversion and supination, injure the anterior talofibular, calcaneofibular ligaments, and subtalor and tibiofibular articulations. Once a ligament is lengthened, over time if the tendon structures are not stabilized, residual dysfunction (hypermobility) may be come long lasting. Typical signs and symptoms include inflammation, pain, decreased range of motion, and swelling. Protocol treatments focus on restoring normal accessory joint motions 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 subluxation and treating accessory motion restriction using joint mobilization. Exercises (closed and open chain) are then implemented to restore range of motion then we add resistance 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 TCM, pre-existing factors that contribute to ankle sprains include the consuming of the qi and Blood (creating LV and K deficiency), accumulation of dampness, invasion of external pathogens (Wind, Cold, Damp), and, of course, Blood stagnation.
Injury mechanism, also plays a big part in differentiation among pre-existing factors creating 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 this qi/Blood become stagnant, the flow within the channels around the affected joint becomes blocked and impaired creates 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 LV supports the tendons by nourishing them through LV Blood, and the K nourishes the bones. Over years of overstraining, working long hours (standing all the time), constitutional weakness and/or prolonged illness, the qi and Blood depletes/consumes specifically the qi and Blood of the LV and K. 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 LV/K functions decline and the K Jing and LV Blood are unable to nourish the tendons and bones sufficiently.
Wind, Cold, Damp Invasion
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 medial 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 leading to stagnation, 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 W-C-D invasion and has accumulated sitting stagnation, this will generate heat. This also disrupts the qi and Blood circulation in the channels causing accumulation, and progresses to stagnation in the channels around the affected joint. In TCM, this is referred to as Damp Heat. Heat presents with redness, feeling of heat around the joint and swelling.
Athletes are exposed to environmental changes that result in possible internal deficiencies. Another factor that pre-disposes athletes to this condition is their diet. Athletes, especially high school and college, tend to eat on the run; constantly eating fast foods. Foods that impair the Spleen's function include consuming too much fatty, greasy food, sweets, and alcohol. This internally gives rise to Damp Heat accumulation over time and this accumulation moves downward into the lower extremities and blocks the channels; thus giving rise to ankle injuries and pain.

Lateral ankle sprains are extremely common within the sports medicine arena, yet treatments only using 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.
