Effect Of Quadriceps Inhibition And Hamstring Facilitation On Knee Control In Hemiplegic Gait.

Abstract

Objectives: To find out the effect of conventional exercises along with quadriceps inhibition and hamstring facilitation on knee control in hemiplegic gait.

Methods: This was an experimental study where60 participants were selected according to inclusion and exclusion criteria and were randomly divided into two groups i.e. group A and B .Group A(n=30) Control, Group B(n=30) experimental group received treatment for 6 weeks for 5 days/week. Upright Motor Control Knee Flexion and Extension Test (UPMCT- KF KE) and Dynamic Gait Index (DGI) were used to assess participant’s pre and post treatment.

Findings: Data was statistically analysed using Student t testfor groupA post intervention UPMCT-KF was (1.36±0.49) with P value 0.0003, UPMCT-KE was (1.36±0.49) with P value 0.0003, and DGI was (8.3±1.53) with P value <0.0001 which shows extremely significant. For groupB post intervention UPMCT-KF was (1.93±0.63) with P value< 0.0001, UPMCT-KE was (2±0.694) with p<0.0001, and DGI was (12.7±2.88) with P value <0.0001 which shows extremely significant.

Between group comparison UPMCT-KF for groupA shows mean difference (1.36±0.49) whereas  groupB  shows a significant mean difference  (1.93±0.63) , UPMCT-KE for groupA shows mean difference (1.36±0.49) whereas groupB shows a significant mean difference   (2±0.694), and DGI groupA shows mean difference  (8.3±1.53) whereas groupB shows a significant mean difference (12.7±2.88).

Conclusion:  Hamstring facilitation improves toe clearance, prevents hip hiking and reduces risk of fall. Quadriceps inhibition helps to prevent knee hyperextension. Combination of these exercises normalizes tone and achieves knee control
