Approximately 40-70% of individuals who suffer an ankle sprain report residual symptoms 6 weeks to 18 months post injury . Balance training is often the first choice of treatment in patients with functional ankle instability (FAI); however the effect of balance training on the ankle proprioceptive sensation in these patients is debatable .
To examine the effect of 4-week balance training intervention on self-reported ankle instability using Cumberland ankle instability tool questionnaire (CAIT) and ankle joint position sense (JPS) using joint position-reposition test in patients with FAI.
Twenty-four recreationally active patients with unilateral FAI were randomized to either the control (n = 12, 34.6±9.04 years, CAIT score = 13.9±4.3) or experimental (n = 12, 33.8±6.4 years, CAIT score = 13.4±3.3) group. Patients in the experimental group were trained on the affected limb using static and dynamic balance components with Biodex balance stability system. CAIT questionnaire was administered at baseline and 6-week post-intervention. The passive ankle JPS at 15 and 30 degrees of ankle inversion on the affected and unaffected limbs was measured at baseline and 4-week post-intervention using Biodex dynamometer. CAIT questionnaire score and mean error in angular displacement at baseline and post-intervention were compared using two-tailed paired Student t tests.
The 4-week balance training program was effective in reducing the self-reported ankle instability and improving the deficit of ankle joint position sense in patients with FAI.
