“…The statistical software Statmate version 2 (GraphPad Software, Inc., CA, USA) was used to determine the required sample size using the primary outcome variable NRS scores for pain, with a power of 80% and a significance level of 0.05 (two-tailed). The standard deviation (SD) was calculated using the data of previous published study on the effects of retro-walking [44]. A clinically important difference between groups of 1.08 in NRS score (SD = 1.19).…”

“…On the other hand, walking backward reduces the compressive loads on the knee joint, making gait easier for the cases. 13 Therefore, a significant difference may not have been found for 3MBWT. Finally, the lack of a significant difference between the groups for mFSST may be due to the absence of adequate balance exercise in the present trial protocol.…”

“…The sample size was calculated with a power of 80% and a level of significance of 0.05 (two-tailed) with a standard deviation based on the previously published study by Rathi et al [20] yielding 60 patients who participated in the study with 20 patients assigned to each group.…”
