Abstract
Introduction :Muscle imbalance and shortness of the muscles around the knee play a very important role in causing genovarum.Muscles play an essential role in the hip, knee and ankle joints for the body. Changes in the length and flexibility of muscles are one of the main causes of movement disorders and posture disorders. genuvarum is one of the most well-known anomalies of the lower limb.Therefore, the aim of this study was to investigate the length of lower limb muscles in girl students with genuvarom.

Methods:The current research method is a descriptive research type that was implemented as a two-group research.two-group research design.The statistical population of the present study includes grade high school girls with an age range of15-17 years in Qom
province, of which100 people were randomly selected based on inclusion and exclusion criteria into two groups of girls with a geno varum (n =50) and a healthy group (n =50). Then, after dividing the groups, the research variables were measured (quadriceps muscle length, hamstring muscle length, gastrocnemius muscle length,tensorfascialata muscle length).The was evaluated using Iset Square software (On Protactor) with an Android smartphone)the measure muscle length.

Results: The results of the present study showed that there was a significant difference between quadriceps muscle length, hamstring muscle length, gastrocnemius muscle length, fascialata tensor muscle، length and between genovarum and healthy groups (P=0/001).

Conclusion: People with Genovarum have muscle shortening compared to their healthy counterparts, and these are abnormal changes in Genovarum that can be corrected in terms of muscle problems in female students with Genovarum using correction protocols.
