Abstract

Objective: The purpose of this study was to research the clinical effectiveness of high-intensity laser therapy combined with exercise on pain, quality of life, and disability in patients with cervical radiculopathy and compared it with that of placebo and exercise alone.

Design: Ninety participants with cervical radiculopathy were randomized into the following three groups: high-intensity laser therapy + exercise ( n = 30), placebo + exercise ( n = 30), and exercise only ( n = 30). Pain, cervical range of motion, disability, and quality of life (36-item Short Form Health Survey) were assessed at baseline and weeks 4 and 12.

Results: The mean age of the patients (66.7% female) was 48.9 ± 9.3 yrs. Pain intensity in the arm and neck, neuropathic and radicular pain levels, disability, and several parameters of the 36-item Short Form Health Survey showed an improvement in the short and medium term in all three groups. These improvements were greater in the high-intensity laser therapy + exercise group than in the other two groups.

Conclusions: High-intensity laser therapy + exercise was much more effective in improving medium-term radicular pain, quality of life, and functionality in patients with cervical radiculopathy. Thus, high-intensity laser therapy should be considered for the management of cervical radiculopathy.
