Abstract

NEED OF THE STUDY: Extensor lag is seen in post traumatic knees as a consequences of either injury or surgery which is caused by muscular weakness, joint distension, joint stiffness and pain.[20,21] There is limited research supporting and validating its use, as well as limited evidence to substantiate the theories used to explain the effects of muscle energy technique (METs).[23,24,25] There is lack of evidence on Muscle energy technique (METs) for quadriceps lag in TKR subjects. AIM: To find out the effectiveness of electrical stimulation and muscle energy technique on pain, peak torque of extensor lag in post total knee replacement subjects. OBJECTIVES:-
• To find out the effectiveness of METS on pain in post TKR subjects.
• To find out the effectiveness of METs on extensor lag in post TKR subjects.
• To find out the effectiveness of METs on peak torque of quadriceps in post TKR subjects.
METHODOLOGY:
• 40 samples were taken with simple random sampling and were assigned to one of the two groups ,group1 and group2 by randomized controlled trail. 20 subjects were taken into each of these groups. Control group was given electrical stimulation and conventional exercises for 3weeks, experimental group was given electrical stimulation with muscle energy techniques and conventional exercises for 3weeks. Subjects were evaluated or assessed at pre and 7th post operative day, and after 3weeks of follow up phase: pain by VAS score, extensor lag by goniometer, peak torque of quadriceps by isokinetic analyser(Biodex).
RESULTS:
• Data analysis was computed by SPSS16.0 version with p value 0.050 to find out the results of the study. The statistics shows improvement in peak torque and decrease in Extensor lag and VAS score in both control and experimental groups. There is significant improvement in experimental group compared to the control group.
CONCLUSION: This study concludes that individually both experimental and control groups were found to be effective in improving terminal knee extension, Range of motion (ROM) and quadriceps strength after 3weeks of exercise. However when both groups were compared, there was a significance of experimental group with greater mean than control group.
