Efficacy of Pnf Stretching Techniques on Hamstring Tightness in Young Male Adult Population

To find out the efficacy of different PNF stretching techniques in improving Hamstring muscle flexibility.Study Design included prepost test control group design. Participants were 30 male students from King Saud University between the age group of 18 to 24 years having Hamstring tightness and without any musculoskeletal disorders formed the sample of this study. Subject’s age, height and weight were matched. Informed consent was taken from all the subjects. Group I acts as a Control group consisting of 15 subjects who receives Self stretch Group II acts as a Experimental group consisting of 15 subjects who receives Therapist PNF stretch. Outcome Measures included straight leg raising test (SLRT) measured by Universal goniometer..Results revealed that both the groups performed stretching 5 times a week for 6 weeks. Four repetitions per session with relaxation period of 15 sec and stretch period of 15 sec. Pre test and Post test values of the Control group and Experimental group were statistically analyzed by means of t-test.The Post test values of Experimental and Control group were analyzed by Chi square test ( test). The Significance level used for 2 this study is P<0.05. This study concluded that though statistically there is no significant difference between self stretch and therapist applied PNF stretch, both are effective treatment methods but Therapist applied PNF stretch is clinically more significant over self stretch.
