EfficacyofSingleStretchingSessionofIliopsoasusingPNFVersusMETon Low Back Pain in Patients with Lumbar Hyper-Lordosis

Lowbackpain(LBP)isamongoneofthemostcommoncausesforwhichanindividualseekstreatmentatphysiotherapy.Therearenumerousaetiologiesoflowbackpain,butnarrowingittomechanicalcausesbringspelvictiltingtolight.In this study, we focus on the LPB related to anterior pelvic tilting, and as it occurs due to the tightness in the iliopsoasmusclethekeytorelievingLBPinsuchconditionsistostretchthatmuscleoptimally.Wehavecomparedtwostretchingapproaches for this purpose, they are proprioceptive neuromuscular facilitation (PNF) and muscle energy technique (MET), however many otherstretchingmethodsexistbutthesetwomethodshavebeenshownhighlyreliableintheevidence. Thepeoplefrom18-60years ofagesufferingfrom LBP,exaggerated lumbar lordosis,and who matched thecriterionfor inclusion werechosenfor thestudy.A group and B group were constructed. Participants in group A were managed byPNF and conventional physiotherapyand those in B were managed byMET and conventional physiotherapy. The same pre and post-test were carried out for each group which was the Numerical Pain Rating Scale (NPRS) used for determining intensity of pain, hip joint extension range of motion (ROM) was takenbyuniversalgoniometerforanalysingiliopsoasflexibilityandlumbosacralangle(LSA)wastakenthroughanX-rayinsupine foridentifyinglumbarlordosisangle. Significantdifferenceswerefoundinpain,hipextensionrangeofmotion,andlumbarlordosis angle between intervention (PNF) and control (MET) groups (P<0.0001), and much more difference was noted between pre-and post-test for intervention group than for control group.The present study of 100 participants, showed that both the techniques PNF and MET are significantly effective for stretchingthetightiliopsoas.AcomparisonofbothtechniquesshowedthatthePNFgrouphadbenefitedmuchmorethantheMET group
