      Research Objectives

      To examine the effects of LLLT upon pain and patient reported function.

      Design

      Study participants underwent examination to determine appropriateness for the use of LLLT. Data was collected initially by a physical therapist followed by application of 12 sessions of LLLT. Data was again collected by a physical therapist following completion of LLLT treatment.

      Setting

      This study was performed within an interprofessional clinic located on a college campus.

      Participants

      Study participants included adults recruited from a college campus and surrounding community. Inclusion criteria included being at least 18 years of age and be experiencing pain in a muscle or joint.

      Interventions

      Study participants received 12 sessions of LLLT using a class 3B laser device. The device used in the study delivered light therapy using a handheld probe which included a combination of LED and laser diodes. LLLT dosage varied according to the anatomical location treated and was based upon guidelines developed by WALT.

      Main Outcome Measures

      Pain was measured using the Numeric Pain Rating Scale (NPRS) pre- and post-treatment. Function was measured using the Patient-Specific Functional Scale pre- and post-treatment.

      Results

      Participants included 31 adults (22 females, 9 males) ranging from 29 to 77 years old, with average age 55 years. Study participants presented with reports of pain in various anatomical location (NPRS for worst pain ranging from 2 to 9). Hip and thigh region pain represented the most commonly reported area of discomfort among study participants, present in 7 of 31 subjects (or 23%). Significant improvements were noted in Current, Best, and Worst reported pain ratings, median of differences from pre to post of -2, -1, and -2 (p < 0.01). Significant improvements were also observed in the Patient-Specific Function Scale measurements, median of differences from pre to post of +1 for first and second listed activities (p < 0.01).

      Conclusions

      LLLT had a positive effect upon numeric pain ratings and reported function in adults with pain.
