Objectives: This double-blind, randomized, prospective, single-centre study evaluated the effectiveness of radiofrequency therapy by the SOLIO Alfa Cure Plus in the treatment of a non-specific low back pain (LBP) Methods: Thirty-seven patients completed pain, disability, and lower back flexibility scales. Randomization was obtained by having an equal amount of sham and real devices and distributing them randomly to patients out of a box where the devices were.

Studies have shown that some generally recommended first-line medications for low back pain (LPB) are only slightly more effective than placebo controls in double-blind randomized trials [10]. For instance, physical exercise in combination with manual therapy often produces short-term results [15], such as the epidural corticosteroid injection that presents a complication rate between 0% and 9.65%. At the same time, various energy sources are thought to have great potential for both general healing and pain relief [11] [12] and there are several available devices that make use of this technology [13].

Infrared therapy (IR) can reach muscles, nerves and even bones, where it reduces inflammation by accessing inner layers of tissues. The use of IR therapy has been shown to accelerate wound healing, ease arthritis knee pain, increase endorphin levels, and activate neuromodulators [19] without any side effects. According to a recent study, IR therapy is beneficial for chronic non-specific LBP sufferers in terms of comfort, function, lumbar range of motion, and back extensor endurance [20].

Radio frequency (RF) therapy shows promise as a healing strategy in a variety of etiologies [22]- [24] and it one of the most common energy sources for producing therapeutic heat levels. RF energy is delivered to soft tissue as part of the mechanism's biophysical therapeutic mode to relieve pain, as well as enhancing collagen formation, vascularization, and collagen structure in the tissue [22]- [24]. Another energy source is the tow-level laser treatment (LLLT), known to induce analgesia, reduce inflammation, and promote healing in a variety of musculoskeletal diseases. This technique is based on the theory that light causes biochemical changes in cells like photosynthesis in plants. [26]. LLLT may also be used as an adjuvant therapy for pain management in patients with neurologic impairments and neuropathic pain [27].

The techniques are potential tools for controlling pain in a variety of etiologies, but additional research appears to be needed to fully develop the therapeutic and mechanistic role of these techniques. No device combining all three approaches has ever been objectively assessed in a randomized clinical trial for pain management. The SOLIO Alfa Cure Plus is the only home-use device with FDA clearance that uses the proprietary synergy of three energy sources (IR, RF, and LLLT), and this study aims to assess the SOLIO Alfa Cure Plus's efficiency in providing pain relief. This technology is the first non-invasive and patented home RF device. SOLIO Alfa Cure Plus uses continuous RF, the internal controller reduces the RF power while reaching the treatment temperature of 39- 42 Celsius.

These three treatment modalities are hypothesized to affect the physiological issue at many levels, causing tissue regeneration and pain relief at the cellular and tissue levels, as well as changing sensory nerves and cell molecular makeup [18], [20], [25], [27]. Our goal was to determine whether the RF component of the treatment has an effect on back pain relief.
