Comparative effects of low-level laser acupuncture and dry needling on clinical and functional outcomes in patients with chronic cervical myofascial pain syndrome: a randomized controlled trial

What the authors concluded

The current study examined the effectiveness of two interventions, Low-Level Laser Acupuncture (LLLA) and Dry Needling (DN), alongside routine physical therapy for chronic cervical myofascial pain syndrome. Both techniques resulted in notable changes in pain intensity, functional disability, range of motion, and various dimensions of health-related quality of life throughout the trial. While DN +

Devices that emit this wavelength

Matched on wavelength within 15nm, since LED bins vary by roughly that much and a tighter match would be false precision. Where we have an irradiance figure, the session length is the time needed to reach this study's dose of 5 J/cm² at that intensity.

Matching a wavelength is not the same as reproducing a trial. Session times assume the device's published irradiance is accurate at the distance it was measured, which on brand-claim figures is often optimistic. Where a device publishes both a peak and an average we use the average, and where it publishes a falloff curve we use the lowest figure, so these times run long rather than short. Clinical protocols also control for spot size, contact and skin type in ways a home device cannot.
