Abstract
Background: Continuous laser acupuncture is widely used to treat chronic pain, particularly fibromyalgia. This condition causes both physical and psychological disability, leading to reduced quality of life. However, little is known about the therapeutic effects of laser acupuncture delivered at pulsed frequency. This study aimed to evaluate the effect of laser acupuncture at 36.5 Hz pulsed frequency, applied to Ryodoraku electrodiagnostic points, on pain intensity and the impact of fibromyalgia.
Methods: DESIGN: Pilot randomized controlled clinical trial.
Setting: Human Performance Research Laboratory at the university's physical therapy clinic.
Participants: Twenty volunteers (aged 40-78 years) with a clinical diagnosis of fibromyalgia syndrome.
Interventions: Participants were randomly allocated into two groups. The Control Group (n = 10) received a 30-min educational lecture on fibromyalgia, while the Experimental Group (n = 10) underwent laser acupuncture treatment twice a week for three weeks.
Main outcome measures: Pain Numeric Rating Scale, Generalized Pain Index, Symptom Severity Scale, and Fibromyalgia Impact Questionnaire.
Results: Compared with the Control Group, the Experimental Group showed significantly lower scores on the Pain Numeric Rating Scale (p < 0.05; effect size = 2.07; power = 0.99), Generalized Pain Index (p < 0.05; effect size = 1.88; power = 0.97), Symptom Severity Scale (p < 0.05; effect size = 2.55; power = 0.99), and Fibromyalgia Impact Questionnaire (p < 0.05; effect size = 2.76; power = 0.99).
Conclusions: Laser acupuncture at 36.5 Hz pulsed frequency, applied to Ryodoraku electrodiagnostic points, demonstrated beneficial effects on pain intensity and functional impact in individuals with fibromyalgia syndrome. Key Points • LASER acupuncture has a positive effect on pain intensity.. • LASER acupuncture has an impact on fibromyalgia syndrome.
期刊介绍:
Clinical Rheumatology is an international English-language journal devoted to publishing original clinical investigation and research in the general field of rheumatology with accent on clinical aspects at postgraduate level.
The journal succeeds Acta Rheumatologica Belgica, originally founded in 1945 as the official journal of the Belgian Rheumatology Society. Clinical Rheumatology aims to cover all modern trends in clinical and experimental research as well as the management and evaluation of diagnostic and treatment procedures connected with the inflammatory, immunologic, metabolic, genetic and degenerative soft and hard connective tissue diseases.
