Effects of Mulligans BLR and CR on Hamstrings Flexibility in Office Workers

Not Applicable

Completed

• Conditions: Muscle Tightness
• Interventions: Other: PNF Contract Relax technique; Other: Mulligan Bent Leg Raise technique

• Registration Number: NCT06074653
• Lead Sponsor: Riphah International University

Brief Summary

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.

Detailed Description

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

Arm && Interventions

Group	Intervention	Description
Experimental group B	PNF Contract Relax technique	Subjects will receive 8 sessions of PNF Contract Relax technique on dominant side
Experimental group A	Mulligan Bent Leg Raise technique	Subjects will receive 8 sessions of Mulligan Bent Leg Raise technique on dominant side

Primary Outcome Measures

Name	Time	Method
Active Knee Extension Test	4 weeks	AKE test with goniometry will be used to evaluate hamstring tightness. Goniometer was used to measure the popliteal angle. When popliteal angle becomes greater than 20 degrees then it's considered as Hamstring tightness. "change will be measured from baseline to 4 weeks"
Lower Extremity Functional Mobility Scale	4 weeks	The Lower Extremity Functional Mobility Scale will tell us about activities done by a healthy individual using their lower limbs. The test-retest reliability is excellent ranging between 0.855 and 0.99. "Change will be measured from baseline to 4 weeks"
