Abstract

Background: Sports knee injury usually occurs by an uncontrolled movement of Lowerextremity.Athleteswithsigni𿿿cantexternaltibialtorsionandknee exion more than 90 degrees during take-off are at risk for developing Patellofemoral pain syndrome. SOCKE exercise is designed for quadriceps muscle training and has a high recruitment impact on the VMO, thereby help to alter the Q-angle mechanism inkneepain.Objectiveofthisstudyistofindout theeffectsofslingopenchain knee extension exercise in altering the Q angle and improving their jumping performance in volleyball players among college students. Method: This Experimental study involves 30 volley ball players & they were divided into 2 groups (experimental & control). Experimental group received SOCKE Exercise along with conventional knee exercise & Control group received only conventional knee exercise with treatment duration of 6 weeks. Pre & post test outcome measures of VJT and Q-angle were assessed. Results: Pre-test and post-test values obtained were analysed using paired &unpaired‘t’ test for28degreesof freedomata5%levelof significance.The mean value of VJT and Q-ANGLE in experimental group 3.00 & 3.07 shows more signi𿿿cantthanmeanvalueofVJTandQ-ANGLEcontrolgroup2.33&2.47. Conclusion: This study concludes that Experimental group who received sling open chain knee extension exercise shows greater statistically signi𿿿cant in reducing Q-angle and improving the jumping performance than control Group who received only Conventional knee exercises.
