BACKGROUNDHamstring tightness is a major contributing factor for lower back pain, lumbar spine disorders and sports related injuries. Many studies has been done to improve the flexibility of hamstring muscle by various techniques such as different stretching techniques myofascial Release Therapy, neuro-muscular therapy and Muscle Energy Technique etc. All of these technique mentioned act at the hamstring muscle level to provide its effectiveness. In a present study we aimed at to find out the effectiveness of suboccipital muscle inhibition technique for improving tightness in hamstring muscle. Hence this study is done to find out the effectiveness of applying suboccipital muscle inhibition technique on distant muscle flexibility in turn to prove the distant muscle relationship. Study is done with the aim to find whether suboccipital muscle inhibition technique can be used along with conventional methods for improving tightness of hamstring muscle.AIMTo compare the effectiveness of suboccipital muscle inhibition technique and static hamstring stretching in normal individuals with hamstring tightness.MethodsIn this comparative study total 165 individuals were screened for tightness of hamstring. Individuals who satisfied the inclusion criteria were selected from the normal healthy population. A total of 100 healthy subjects of both genders between the age of 18 and 25 were recruited in this trial. After doing block randomization subjects were assigned to two groups ,in Group A 50 subjects were given suboccipital muscle inhibition technique for 5 sessions for 5 consecutive days. Another group 50 subjects were given static stretching to both the lower limbs for 30 seconds followed by 15 seconds relaxation, for 5 sessions for 5 consecutive days.RESULTSActive knee extension test using Mann Whitney U test in both suboccipital muscle inhibition technique and static hamstring stretching group shows no difference(p=0.623) for pretreatment, while significant result immediately post treatment (0.002) and statistically significant result in baseline parameters after 5 sessions of treatment (0.000)Forward flexion distance test using Mann Whitney U test in both suboccipital muscle inhibition technique and static hamstring stretching group shows no significant difference(p=0.088) for pretreatment and also for immediately post treatment (0.893) but shows statistically significant result in baseline parameters after 5 sessions of treatment (0.009)CONCLUSIONSuboccipital muscle inhibition technique and static hamstring stretching are both effective in improving the flexibility of hamstring muscle. The Suboccipital muscle inhibition technique is more effective compared to static hamstring stretching in normal healthy individuals with hamstring tightness.
