The current research aims to design and validate a strength program using isokinetic device system and specific therapeutic exercises for ‎rehabilitation of soccer players with iliotibial band syndrome and to identify the effectiveness of the recommended rehabilitation program. The researcher used the experimental approach (one-group design) with pre- and ‎post-measurements‎. The research sample consisted of 4 soccer players who have been registered with the Egyptian Football Federation (premier league) with iliotibial band syndrome ‎volunteered in this study, Their ages ranged from 18 to 27 years ‎. The researcher used Isokinetic device system (SP3-I37). The following parameters were measured for both the healthy and injured limbs: the Peak Torque at flexion and extension at the 90/180 ° angle, range of motion (ROM) of the knee joint, the balance, the circumference of the thigh muscles and the degree of pain
