Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Despite being a clinical electrotherapy technique currently widely used by physiotherapists, there are few clinical trials on the application of monopolar electrical diathermy by radiofrequency emission (MDR) in ailments of lumbar origin caused by myofascial trigger points. The difference with other systems that use high-frequency electrophysical agents such as short waves or microwaves lies mainly in the ability to penetrate the tissues, producing a thermal effect at a greater depth.
Due to all the structural and functional alterations that occur in chronic non-specific low back pain, this randomized clinical trial project was born, with the aim of providing an answer to the disabling symptoms suffered by patients with chronic non-specific low back pain, searching for tools of safe and effective treatment from the field of Physiotherapy, which report a benefit in the symptoms, functionality and quality of life of patients diagnosed with chronic non-specific low back pain caused by PGM.
A total of 74 people diagnosed with non-specific chronic low back pain of more than 3 months of evolution and who are not currently undergoing any type of treatment will be recruited, with ages between 35 and 65 years. A random distribution will be made into two treatment groups (monopolar diathermy by radiofrequency versus placebo).
The 37 subjects of the experimental group (EG) will receive an application of monopolar electrical diathermy by radiofrequency emission (MDR) by means of the Physicalm® device (developed by the electro-medicine company Biotronic Advance Develops SL), on the lumbar muscles by means of rotary movements and translation, adapting to the muscle fibers of the lower back, contacting and applying the treatment to the active myofascial trigger points of the following muscles: quadratus lumborum, multifidus and iliocostalis, following the PGM maps described by Travell and Simons. A pulsed emission of 840 KHz and 30v will be carried out dynamically for a treatment time of 20 minutes. 3 weekly sessions will be performed for 3 weeks, a total of 9 treatment sessions.
The 37 subjects in the control group (CG) will be administered a placebo treatment consisting of the same execution protocol as the EG, but with a non-emitting device whose software and hardware will be exactly the same as that used in the EG. The intervention will be simulated for 20 minutes.
A pulsed emission of 840 KHz and 30v will be carried out dynamically for a treatment time of 20 minutes. 3 weekly sessions will be performed for 3 weeks, a total of 9 treatment sessions.
The outcome assessor and study statistician will be blinded throughout the entire process.
A baseline assessment of the primary and secondary outcome measures will be performed before randomization of the participants to the different groups, an immediate post-treatment assessment (1 day after the last intervention) and an assessment two months after the end of the procedure intervention (follow-up).

Experimental: monopolar dielectric diathermy
The Experimental Group formed by 30 subjects will undergo an application of monopolar electrical diathermy by radiofrequency emission (MDR) using the Physicalm® device developed by the electro-medicine company Biotronic Advance Develops SL, on the lumbar muscles by means of rotary movements and translation, adapting to the muscle fibers of the lumbar area. A pulsed emission of 840 KHz and 30v will be made dynamically during a treatment time of 20 minutes. 3 weekly sessions will be performed for 3 weeks, a total of 9 treatment sessions.
