The tool used in this method is Random allocation software. In this software; random sequence is determined by specifying the number of groups(2 groups), the type of groups (intervention and control) and the sample size , Blinding description: After data collection& entry of them in SPSS software, data file that don't contain of patient names, available to the data analyzer.The data analyzer will not be aware of the type of intervention, participants grouping& researcher hypothesis to don't create bias in statistical results interpretation. N/A sprain of ankle. Intervention 1: Intervention group: Common physiotherapy (Ultrasound, Infra-Red, Trans-cutaneous Electrical nerve Stimulation, Tibialis Anterior& Peroneus longus muscles Resistance exercise by Elastic band and balance exercise by tilt board) with neuromuscular exercises taken from Lephart protocol for 12 sessions,3 times a week for 4 weeks, any session time: 1h, 20 min. Intervention 2: Control group: Common physiotherapy (Ultrasound, Infra-Red, Trans-cutaneous Electrical nerve Stimulation, Tibialis Anterior& Peroneus longus muscles muscles Resistance exercise by Elastic band and balance exercise by tilt board) for 12 sessions,3 times a week for 4 weeks, any session time: 1h.
