Context: Chronic ankle instability (CAI) is one of the most common chronic conditions in the world, resulting in millions of dollars contributed to the health care system. Joint mobilizations have been shown to effectively improve patient and disease-specific impairments secondary to CAI. The ability for patients to complete an effective manual therapy intervention without the need for continuous visits to a health care provider can alleviate burdens on the health care system and improve patient satisfaction. Objective: To examine the effect of clinician-applied Maitland talocrural joint mobilization and self-mobilization (Self-Mob) on dorsiflexion range of motion (DFROM), dynamic balance, strength, and perceived function in those with CAI. Design: Single-blind randomized trial. Setting: Research laboratory. Participants: A total of 18 participants (7 males and 11 females; age = 20.78 [2.02] y, height = 67.66 [3.83] cm, limb length = 87.74 [5.05] cm) with self-reported CAI participated. Interventions: The participants received 6 interventions over a 2-week period. The participants received either Maitland grade III anterior-to-posterior talocrural joint mobilizations or weight-bearing lunge Self-Mob. Each intervention consisted of four 2-minute sets, with a 1-minute rest between sets. Main Outcome Measures: The DFROM (weight-bearing lunge), dynamic balance (Y-Balance Test), isometric strength, Foot and Ankle Ability Measure Quick, Disablement of the Physically Active modified, Fear Avoidance Beliefs Questionnaire, and Tampa Scale of Kinesiophobia-11 were measured preintervention and postintervention. Results: Dynamic balance, isometric strength, and perceived function significantly improved in both groups at postintervention. The DFROM significantly improved in the Self-Mob group. Higher individual responder rates were demonstrated within the Self-Mob group compared with clinician-applied mobilizations. Conclusions: Clinician-applied mobilizations and Self-Mobs are effective interventions for improving dynamic balance, isometric strength, and perceived function. Application of Self-Mobs can effectively improve DFROM compared with joint mobilization. Self-Mobs may be an effective intervention to incorporate into a home care plan.
