About this study

Official title: Evaluation of the Efficacy of Light Therapy for the Treatment of Back Pain in Pilots

Back pain is a common complaint among pilots. Current treatments include physiotherapy and chiropractic manipulations. Low-level laser irradiation (LLLI) in the visible to near-infrared range was shown to reduce neck and low back pain.

The purpose of the study is to evaluate the efficacy of Light Therapy for treatment of back pain in pilots.

Read the detailed description

Background: Lumbar spine disorders are common conditions in pilots of various aircraft with etiology related to sub-optimal ergonomics, exposure to G-forces, the weight of the head gear and exposure to extensive vibrations. Current treatments include physiotherapy and chiropractic manipulations. Low-level laser irradiation (LLLI) is a non-ionizing, non-thermal irradiation within the visible to near infrared range of the light spectrum. LLLI has been used widely for alleviation of pain in inflammatory processes and acceleration of wound healing. A variety of clinical studies show that LLLT in the near infrared range may be useful in the treatment of back pain.

Objective: To evaluate the efficacy of Light Therapy for treatment of back pain in pilots.

Study design: Prospective, randomized, controlled double blind. Volunteers will receive biweekly physiotherapy treatment for 3 weeks. In addition to the physiotherapy treatment, half the volunteers will receive light therapy and half sham irradiation. Study evaluations will include physical examination by an orthopedic surgeon, subjective pain level by visual analogue scale, validated low back functional questionnaires, a generic functional questionnaire, and patient satisfaction scores. Volunteers will be invited for evaluations at 1 and 3 months after the final treatment.

    Measured: within 4 months

Secondary outcomes (1)
  1. Change in pain level by VAS after 3 weeks compared to baseline (before treatment)

    Measured: 3 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing GaAlAs 808nm laser in people with Back Pain, run by Hebrew University of Jerusalem at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to reach minimal important change in pain level by visual analog scale (VAS) (time frame: within 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2025.
