- Brief Summary
Background: Low back pain (LBP) affects approximately 51-57% of hospital nurses and nurses' aides in Europe. New high-risk groups include home- and long-term-care nurses and physiotherapists. A number of European countries are experiencing a shortage of healthcare workers. Light therapy has been shown to be an effective treatment for various musculoskeletal disorders, including lateral epicondylitis, temporomandibular joint pain, carpal tunnel syndrome, and delayed-onset muscle soreness. A systematic review and meta-analysis demonstrated that low-level laser therapy is an effective method for relieving non-specific chronic low back pain (NSCLBP). However, the efficacy of light-emitting diode (LED) therapy for NSCLBP is disputed. This study aims to evaluate the effect of LED therapy on NSCLBP.
Methods and analysis: The investigators conducted a prospective, double-blind, randomized placebo-controlled trial of 148 patients with NSCLBP. The patients were randomly assigned to two groups: intervention group, where patients received LED photobiomodulation therapy three times a week for 2 weeks, and the control group, where patients had sham treatment only three times a week for 2 weeks. Primary outcome measures included the visual analog scale for pain, lumbar active range of motion assessments, and chair-rising times. Secondary outcome measures included a Multidimensional Fatigue Inventory, Fear-Avoidance Beliefs Questionnaire, and the Oswestry Disability Index. The outcome measures were assessed before therapy and 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 6 months after the first interventions were completed.
Discussion: This study is a prospective, single-center, double-blind, randomized, controlled study. This study aims to research the efficacy of a 2-week LED program for NSCLBP working nurse. The results will be useful for patients, working nurses, nurses' aides, and other healthcare workers with chronic low back pain.
Trial registration number: This protocol was registered in ClinicalTrials.gov, under the number 108-088-F.

- Primary Outcome Measures
Name Time Method measure assessing change of Chair-rising time between baseline to every time points 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 6 months Chair-rising time, wherein the time required for participants to rise five times from a seated position in a standard chair to a standing position as quickly as possible, without using their arms for support, was measured. A longer chair-rising time represents greater physical function limitations.
measure assessing change of Lumbar active range of motion between baseline to every time points baseline, 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 6 months Including forward flexion, extension, and right and left rotations and were measured in degrees using a back range of motion instrument.
measure assessing change of 100-mm visual analog scale (VAS) between baseline to every time points 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 6 months A 100-mm visual analog scale (VAS), which was used for low back pain assessment. The anchor terms of the VAS were 0 (no pain) and 10 (maximum pain imaginable). Higher VAS scores indicate greater pain intensity.
