Introduction: Chronic ankle instability (CAI) is characterised by a subjective feeling of recurrent instability, continuedepisode of giving way and self-reported disability. A wealth of literature is available reporting causes and risk factors related to CAI,still thereis a lack of understanding regarding rehabilitation procedures. Aim: To compare effect of BOSU ball and wobble board along with strength training on muscle strength, dynamic balance, agility and functional performance in recreational runners with CAI. Materials and Methods: It was an experimental study design conducted at Physiotherapy OPD of SGT Hospital, Gurugram. Data collection was done from July 2019 till October 2019. Analysis and report writing took 2 months i.e from November 2019 till December 2019. 60 male runners in the age group of 18-35 years with CAI were randomly divided into two groups i.e. A (Wobble board) and B (BOSU Ball) with 30 players in each group. All subjects were evaluated for ankle muscle strength, agility, dynamic balance and functional performance as measured by Manual muscle tester, T-test, Y balance test and figure of eight hop test respectively on day one and last day of 3rd and 6th week of intervention. SPSS software version 20.0 was used to analyse result. Mean and Standard deviations were calculated. ANOVA and Student T test was used for analysing inter group differences. Results: The statistical findings in this study postulate that both groups had significantly improved fitness and skill related variables but BOSU ball group showed highly significant improvement compared to wobble board group (p<0.05). Conclusion: The current results support that sensorimotor training can be progressed in difficulty by systematically reducing the base of support with help of BOSU ball.
