Therapeutic efficacy of mulligan’s mobilization versus low level laser therapy for the management of tennis elbow: A comparative study
Background and Objectives: Tennis elbow is most common lesion of the elbow affecting the tendinous origin of the wrist extensors especially ECRB. In physiotherapy clinical practice, different outcome measures were used to evaluate functional recovery in tennis elbow. This study has used two outcome measures for evaluating the functional recovery in tennis elbow and they are Visual Analogue Scale (VAS) and grip strength. The objectives of this study to find out and compare the efficacy of Mulligan’s MWM Versus Mulligan’s MWM in combination with Low level laser therapy, to reduce pain and improve grip strength in Tennis elbow. The method used in subjects with known cases of chronic tennis elbow (three or more than three months) diagnosed by clinical confirmatory tests by the specialists; were chosen for the study. After dividing the subjects into 2 groups of 25 each, they were pre- tested using hand dynamometer for the grip strength and visual analogue scale (VAS) for pain intensity. The first group were given Mulligan`s Mobilisation with Movement and second group were given Low Laser Level Therapy and Mulligan`s Mobilisation with Movement for thrice a week for three weeks. The patients were assessed for pain intensity using visual analogue scale (VAS) and for grip strength using hand dynamometer by the end of third week. The results were computed and analyzed to see which group has better improvement. The results of the study in the group A, the VAS score came down from 6.32 to 3.28 by the end of third week of treatment and the grip strength increased from 11.36 to 14.96 lbs by the end of third week. In the group B, the VAS score came down to 2.08 from 6.48 by the end of third week. The grip strength increased from 11.68 lbs to 16.40 lbs by the end of third week. So, there was a significant improvement in grip strength and reduction in VAS in group A and group B. Also there was a significant improvement in grip strength and VAS in group B as compared to group A. The conclusion in this study, both the groups statistically showed significant response to their interventions. The mean score in case of VAS is less and in case of HGD is high for Mulligan`s MWM and Low Level Laser Therapy as compared to Mulligan`s MWM alone. Mulligan`s MWM and LLLT was found to be more effective than the Mulligan`s MWM alone to reduce the pain and to increase grip strength in treating Tennis elbow.
