A Study to Compare the Effects of Mulligan Traction Straight Leg Raise Technique, and Propeoceptive Neuromuscular Facilitation (Hold Relax) Technique on Tightness, and Strength of Hamstring Muscle among Young Adults

Flexibility is defined as the ability of a muscle to lengthen, allowing one joint or more to move through a range of motion (ROM), and is an essential component of normal biomechanical functioning. Hamstring tightness can occur due to the sedentary lifestyle which is the main reason for postural abnormalities. Therefore, it is important to have optimal muscle flexibility for optimal performance. In this line of thought, the present study is designed to compare the effects of Mulligan Traction Straight Leg Raise Technique and Proprioceptive Neuromuscular Facilitation hold relax technique on hamstring tightness among young adults. AIM OF THE STUDY- “To compare the effects of mulligan traction straight leg raise technique and proprioceptive neuromuscular facilitation (hold relax) technique on tightness and strength of hamstring muscle among young adults”. METHODOLOGY- The total duration of the study was one and a half year. Subjects meeting the inclusion and exclusion criteria were selected in the study. A minimum of 60 subjects, both male and female with age between 18-25 years, were selected for the study and subsequently divided into three groups with minimum of 20 subjects in each group. Group A (control group) was given warm up and hot pack for 15 minutes. Groups B and C were experimental groups. Group B was given Mulligan Traction Straight Leg Raise technique in addition to warm up and hot pack. Group C was given PNF hold relax technique in addition to warm up and hot pack. The baseline data was recorded on first day (pre intervention) and on last day of second week (post intervention). All the interventions were performed once a day, five days a week for two weeks. DATA ANALYSIS- The collected data will be analysed using ANOVA and other statistical tests as appropriate (SPSS software). RESULT- The result of present study shows that PNF hold relax is more effective in improving flexibility of the hamstring muscle than Mulligan TSLR.
