Objectives:
This study evaluated the effects of Class IV laser therapy on pain, Fibromyalgia (FM) impact, and physical function in women diagnosed with FM.
Design:
The study was a double-blind, randomized control trial.
Setting:
Testing was completely at the university and Rheumatologist office and treatment was completed at a chiropractic clinic.
Participants:
Thirty-eight (38) women (52+/- 11 years; mean+/- standard deviation) with FM were randomly assigned to one of two treatment groups, laser heat therapy (LHT; n=20) or sham heat therapy (SHT; n=18).
Intervention:
Both groups received treatment twice a week for 4 weeks. Treatment consisted of application of LHT or SHT over seven tender points located across the neck, shoulders, and back. Treatment was blinded to women and was administered by a chiropractic physician for 7 minutes.
Outcome Measures:
Participants were evaluated before and after treatment for number and sensitivity of tender points, completed the FM Impact Questionnaire (FIQ) and the pain question of FIQ, and were measured for function using the continuous scale physical functional performance (CS-PFP) test. Data wew evaluated using repeated at P</=0.05.
Conclusions:
This study provides evidence that LHT may be a benificial modality for women with FM in order to improve pain and upper body range of motion, ultimately reducing the impact of FM.
