Chronic ankle sprains have been attributed to poor sensorimotor control, resulting in “functional ankle instability.” First described in the 1960’s by Freeman and Wyke, functional ankle instability has been postulated to result from a lack of proprioceptive information from the ankle due to “deafferentation.” Functional ankle instability is associated with chronic ankle sprains; patients with functional ankle instability may have normal strength and ligament structure, yet continue to suffer ankles sprains. Progressive balance exercise programs have been shown effective at reducing functional instability and recurring ankle sprains. Sensorimotor training programs for ankle instability often include balance exercises that use foam pads such as Thera-Band® Stability Trainers.

Researchers at the University of Kentucky developed a progressive balance training program for patients with chronic ankle instability. The program lasted 4 weeks and focused on dynamic balance stabilization in single-leg stance. Exercises included progressions in hops and single-leg balance using foam pads and 6-pound medicine balls. The results of their first study, published in Medicine and Science in Sports and Exercise in 2008, found that their program significantly improved function and postural control in chronic ankle sprain patients.
