A 4-Week Multimodal Intervention for Individuals With Chronic Ankle Instability: Examination of Disease-Oriented and Patient-Oriented Outcomes.

contextIndividuals with chronic ankle instability (CAI) experience disease- and patient-oriented impairments that contribute to both immediate and long-term health detriments. Investigators have demonstrated the ability of targeted interventions to improve these impairments. However, the combined effects of a multimodal intervention on a multidimensional profile of health have not been evaluated.

objectiveTo examine the effects of a 4-week rehabilitation program on disease- and patient-oriented impairments associated with CAI.

participantsTwenty adults (5 males, 15 females; age = 24.35 ± 6.95 years, height = 169.29 ± 10.10 cm, mass = 70.58 ± 12.90 kg) with self-reported CAI participated. Inclusion criteria were at least 1 previous ankle sprain, at least 2 episodes of "giving way" in the 3 months before the study, and a Cumberland Ankle Instability Tool score ≤24. INTERVENTION(S): Individuals participated in 12 sessions over 4 weeks that consisted of ankle stretching and strengthening, balance training, and joint mobilizations. They also completed home ankle-strengthening and -stretching exercises daily. MAIN OUTCOME MEASURE(S): Dorsiflexion range of motion (weight-bearing-lunge test), isometric ankle strength (inversion, eversion, dorsiflexion, plantar flexion), isometric hip strength (abduction, adduction, flexion, extension), dynamic postural control (Y-Balance test), static postural control (eyes-open and -closed time to boundary in the anterior-posterior and medial-lateral directions), and patient-reported outcomes (Foot and Ankle Ability Measure-Activities of Daily Living and Foot and Ankle Ability Measure-Sport, modified Disablement in the Physically Active scale physical and mental summary components, and Fear-Avoidance Beliefs Questionnaire-Physical Activity and Fear-Avoidance Beliefs Questionnaire-Work) were assessed at 4 times (baseline, preintervention, postintervention, 2-week follow-up).

resultsDorsiflexion range of motion, each direction of the Y-Balance test, 4-way ankle strength, hip-adduction and -extension strength, the Foot and Ankle Ability Measure-Activities of Daily Living score, the modified Disablement in the Physically Active scale-physical summary component score, and the Fear-Avoidance Beliefs Questionnaire-Physical Activity score were improved at postintervention (

conclusionA 4-week rehabilitation program improved a multidimensional profile of health in participants with CAI.
