Randomized allocation
Initially, 29 patients were enrolled to study; five of them did not fulfill the inclusion criteria. The eligible participants were 23 patients who were randomly allocated into two groups: (1) Nintendo Wii Fit system (named Wii group) as an intervention group, and their exercise program was given by a proposed ES. (2) The control group received a conventional ACL rehabilitation program (named CL group). Three athletes were also excluded in the next stage (Fig. CONSORT Flow diagram of the participantsThe patients who met the inclusion criteria were randomly assigned to one of the groups in a 1:1 ratio using a computer-generated random allocation sequence using a stratified block randomization process. Patients were blinded to treatment. Also, assessors were blinded to the allocated group of patients.
