The aim of this research is to compare the effect of mulligan bent leg raise and contract relax technique on hamstring flexibility in office workers with sedentary life styles.

Flexibility is regarded as a crucial component of typical biomechanical operation. A tight hamstring increases the risk of frequent impairment to the associated musculature and bony structure. Hamstring muscles are associated with lumbar spine, pelvic and lower limb movement disorders and have been connected to low back discomfort and abnormal gait pattern. It has been observed that long sitting and sedentary life style is directly related to reduce the hamstrings flexibility, so the persons with tight hamstrings are more prone to develop musculoskeletal disorders if not addressed properly. Previous research has shown that contract relaxation and Mulligan's bent leg are both useful for increasing hamstring flexibility. But there hasn't been much research comparing the two methods, Mulligan bent leg lift and contract relax, for hamstring muscle stiffness in middle age office employees; instead, it was done in young people and athletes. Hence, the aim of present work is to study and compare the effectiveness of contract relax and Mulligan bent leg raise in middle age office workers with long sitting hours having hamstring tightness

Inclusion Criteria:

• Middle age men and women (30 to 45 years)
• Working/ sitting hours ≥ 36 hours per week.
• Real estate and IT office workers.
• Participant with positive Active Knee Extension Test: A lag of 20degrees is considered normal from full extension, anything less than 20degrees is considered as hamstrings tightness

Exclusion Criteria:

• History of knee and hip injury
• Neurological impairment
• Other orthopedic conditions i.e., hip fracture, THR, TKR etc
• Fracture of lower limb
