BACKGROUND: ACL injuries are common in physically active individuals, lead to pain, instability, and reduced function. Berg balance scale and 8 foot up and go test was used to assess balance in post ACL reconstruction population PURPOSES: To find out the effect of task-oriented progressive resistance training versus perturbation-based balance training to improve balance in post ACL reconstruction METHODOLOGY: 30 subjects who have undergone ACL reconstruction were selected from Sri Venkateshwaraa Medical College and Research Institute, Pondicherry, They were allocated and divided into two groups: group A (n = 15) task-oriented progressive resistance training and group B (n = 15) perturbation-based balance training for 6 week, The outcome measure (berg) balance scale and 8-foot up-and-go test) were measured in the pre- and post-test for a 6-week period. RESULTS: Data analysis was done by unpaired ‘t' test and paired ‘t' test for the between-group and within-group analysis, respectively, The statistical analysis done with unpaired ‘t' test within Group A and Group B analysis shows significance (p<0.001) Which shows that Group A must be significant than Group B, it have been concluded that Group A shows improvement balance in post ACL reconstruction population than Group B. CONCLUSION: The study concluded that task-oriented, progressive resistance training (Group A) shows more significant when compared with perturbation based balance training (GROUP-B) in improving balance in post ACL reconstruction population.
