BackhroundsThe aim of this study was evaluation the effect of low level laser and light therapy onrange of motion in patients with total knee arthroplasty.MethodsMaterial and methods: In this study we evaluated 45 cases of total knee arthroplastyin hospital for three months. The patients were under went in three approachesintervention (LASER, LIGHT and CONTROL group) in order to improve range of motionand reduce rehabilitation period in all groups. forty-five randomized patients wereenrolled in this study; they were undergoing primary total knee arthroplasty.ResultsResults: ROM in LASER and LIGHT groups were changed significantly (p value<00001/0)There was significant difference ROM between control group and intervention groups,It should be noted ROM in the LASER group changed more than LIGHT group. KneeROM after knee arthroplasty in laser group improved significantly (p<0.0001).ConclusionsDiscussion and Conclusion:The result of the present trial research showed using LL-Laser therapy and Light therapycan reduce the rehabilitation period and improve range of motion in patients with totalknee arthroplasty.
