Abstract
Background: Due to the lack of consensus on the dosage of laser which can be beneficial for the patients with knee osteoarthritis needs to be established.
Aim: The aim of the present study was to examine the effect of different doses of LASER in patients with knee osteoarthritis.
Study design: Experimental study design comparative in nature.
Sample size: 60
Procedure: Subjects in the age range of 40-65 years were recruited and divided randomly into 3 groups with group A receiving laser dose of 4 J/cm2, group B receiving dose of 5J/cm2 and group C receiving dose of 3 J/cm2. Conventional physiotherapy and strengthening exercises was given to all the three groups. Whole procedure was continued for 2 weeks. Outcome measures included VAS, WOMAC, ROM of flexion of both right and left knees.
Results: The pre and post treatment readings of VAS, WOMAC and ROM of flexion of both knees showed significant improvement as evident from paired t-test score at 5% level of significance. The findings of ANOVA test showed significant difference of VAS and WOMAC among the three groups. Post-hoc analysis using Tukey?s HSD showed that the mean difference was statistically significantly difference between group B with group A and C for both the VAS and WOMAC.
Conclusion: Though statistically the results came out to be significant in all the three groups but clinically more improvement was noticed in group B than in other groups. More studies are required to establish the dose used in group B i.e. 5J/cm2.
