Trial Outcomes & Findings for Low Level Laser Therapy With Physical Therapy for Chronic Musculoskeletal Pain (NCT NCT02785432)

NCT ID: NCT02785432

Last Updated: 2020-07-07

Results Overview

Perceived pain on scale of 0-10 (0=no pain, 10= extremely severe pain). Pain during the previous 24-hour period (best, worst, current) will be measured at T1-T8. The average of 3 scores will be used.

Measure
Sham Low Level Laser
Treatment will be administered 2x/w x 4 weeks as a standalone, then 2 times/week x 4 weeks in conjunction with standard physical therapy and counseling. The clinician will apply 10 minutes of low level laser therapy at a dosage of 0 watts for a total of 0 joules based on body surface area treated. Application will be with light to moderate contact pressure based on patient tolerance (should be no additional discomfort from laser). Area for administration will include 6 minutes of application along spine (C2-S1), and 4 minutes of application either to bilateral upper extremity or bilateral lower extremity based on areas of primary pain complaint. The contact head applicator will be used if soft tissue contact is tolerable. Otherwise, the non-contact head will be utilized. Sham low level laser: Sham laser will be administered using the same time and contact exposure as delivered for the active group, but without any energy delivered.
Active Low Level Laser
Treatment will be administered 2x/w x 4 weeks as a standalone, then 2 times/week x 4 weeks in conjunction with standard physical therapy and counseling. The clinician will apply 10 minutes of low level laser therapy at a dosage of 15-25 watts for a total of 9,000-15,000 joules based on body surface area treated. This equates to standard acceptable dosing of 6-10 j/cm2 over the larger area of treatment. Areas for application and contact will otherwise be consistent with the sham group.

SECONDARY outcome

Timeframe: Baseline, 4 week, 8 week

The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality.
