Male and female participants with tightness of hip flexor will be recruited for this study. Written consent form for the voluntary participation of the subjects will be taken. Every subject will be assured that there will be no personal harm and the information obtained from them will be used only for research purpose and their privacy will be maintained. The entire demographic data such as name, age, gender, occupation, address, weight and height of each subject and general information about each subjects will be documented in the pre designed Performa. Height of the subject will be measured by measuring tape and the weight will be measured with the help of calibrated digital weighing machine and BMI will be calculated using the standard formula [BMI= weight (in kilograms) / height (in meter²)] subjects are tested for hip flexor tightness with help of modified Thomas test. The patient will be asked to sit at the edge of the couch and lie back on the couch holding both the knees across the chest ensuring the straightening of the lumbar spine and posterior rotation of the hip. The patient will lower the affected extremity by keeping the contralateral side to the chest himself/herself. 2 trails of each angles of hip flexion, knee flexion and hip abduction will be taken to determine the length of iliopsoas, quadriceps and TFL/ITB flexibility, respectively.
