Summary Of Functional Ankle Instability

Functional ankle instability has been described as having continuing episodes of the ankle giving way, weakness, and general disability. This is usually caused by deficits in strength, proprioception, and functional performance; which is why often rehabilitation is based on improving these. Often what causes these deficits is the result of having multiple ankle sprains. The article is a randomized control trial aimed at “comparing the effects of resistance-bands (RBP) and proprioceptive neuromuscular facilitation (PNF) on strength, dynamic balance, functional performance and perceived instability in individuals with chronic ankle instability” (Hall, Docherty, Simon, Kingma, Klossner, 2015). The study had a total of 39 participants from a university setting, 17 of them men and 22 of them women. All participants had to have chronic ankle instability and took a Functional Ankle Instability Questionnaire to determine this. The individuals were separated randomly into, a control …show more content…
A pre-test was given before intervention and a post-test done after the intervention. The tests were a manual muscle test using an isometric dynamometer in directions of dorsiflexion, plantarflexion, inversion and eversion, a figure eight hop test, a triple-crossover hop test, an ankle instability visual analog and a Y-Balance test. These tests were focused on the dependent variables of strength, dynamic balance, functional performance and perceived ankle instability. The independent variables were the RBP and PNF rehabilitation interventions. The control group only participated in the pre-test and post-test; where the other groups received rehab sessions three times a week for six weeks. The RBP group used rubber
