Is there a measurable reason why an athlete will sprain an ankle with a turning activity that has been done thousands of times before with no trauma? Orthopedist Jose Palomar Lever, MD,1 recently evaluated 200 asymptomatic patients for the involvement of ligaments in many of the different joints of the foot.
The research design consisted of spreading apart the ligament and then manual muscle testing 40 different muscles throughout the body to see how this inhibits or facilitates remote muscles.
Twenty-one joints and ligaments were tested in these 200 patients, and the specific correlations between the joints and ligaments and the muscles they affected were listed. Generally, the calcaneal ligaments were found to affect pelvic and lower limb muscles, while the talar ligaments were more involved with neck, upper thoracic and shoulder muscles.
Lever suggests, "Because of the importance of foot proprioception and the foot's relationship to so many body problems from neurological disorganization to gait imbalances, fascial disturbances, and the inhibition of so many muscles when faulted, physical evaluation of patients should include more attention to the feet."
