Objective: In this research the effect of perturbation training on correlation index of detrended fluctuation analysis index (&alpha) of anterior cruciate ligament deficient (ACL) patients was evaluated using nonlinear dynamic methods.

Materials & Methods: The study was done on ten male athletes with at least 6 months elapse after their ACL lesions. Subjects were selected using non-probability sampling technique. Stride time for about 270 gait cycles for each patient was recorded and used for detrended fluctuation analysis.

Results: Analysis showed difference in values of &alpha between primary and shuffled data which indicates a non-trivial trend of data structure. According to the range of &alpha (0.5>&alpha>1), long time correlation between gait cycles was found. Also, the results showed no significant difference on &alpha before and after training (P=0.515).

Conclusion: The results showed persistent patterns in time series which are similar to slow/ speed walking patterns. Also, it can be concluded that, according to their correlation values, ACL deficient patients had a similar behavior to healthy people.
