“…This type of transmission adds important advantages because of the selectivity of the energy deposits on the therapeutic targets and its lack of side effects. Dielectric capacitive PEMS transmission [37] allows energy to be transferred noninvasively to deeper tissues in a more controlled and accurate manner than conventional electrotherapy or thermotherapy systems [38]. This system is based on tissue dielectric charge capacity [54] to deeply transport high-frequency energy and a higher degree of focalization and density of energy applied while avoids warming the surface [38].…”

Low energy pulsed electromagnetic signals (PEMS) therapy, in the field of bioelectronics, has been suggested as a promising analgesic therapy with special interest in treating conditions with poor response to pharmacotherapy. This study evaluated the effectiveness of PEMS therapy on the treatment of chronic low back pain patients with a neuropathic component. A group of 64 individuals with such condition was allocated to a 2-week treatment period (10 twenty-minute sessions on consecutive days) with an active PEMS therapy device or an inactive device in random order. The pain was assessed on a visual analog scale, and the functional status was assessed using the SF-12 questionnaire. The visual analog scale scores were lower after treatment than at baseline but only in the group treated with the active device. According to the DN4 score, neuropathic pain decreased in both experimental groups with respect to baseline, but this was only significant for the group treated with the active device. Similarly, an improvement in the SF-12 and Medical Outcomes Study (MOS) sleep scale components was reported. The study demonstrated that low-energy PEMS therapy was efficient in reducing pain and improving function in chronic low back pain patients with a neuropathic component.

“…The PEMS therapy application was dynamic, with a continuous rotation and translational movement on the dorsolumbar spine, making focused energy deposits in the areas involved in the painful process. Five milliliters of almond oil were used to improve gliding along with the 20-min application of PEMS [37,38].…”

“…Participants received MDR treatment with a dynamic pulsed emission of 840 kHz and 30 V, with continuous rotary movement covering all the front surface of the knee from lateral to medial aspect. Five milliliters of almond oil were employed as the dielectric substance so as to improve gliding throughout the 12-min MDR application [ 22 , 23 ] ( Figure 1 ).…”

“…PPAS is an easy-to-use, reliable, useful and validated tool in order to assess subjects' apprehension of receiving electrical stimulation therapy [21]. Exclusion criteria included all cases where the use of MDR was contraindicated (fever, active process of tuberculosis, pregnancy, infected wounds, osteomyelitis, tumors, presence of implanted electronic devices such as pacemakers, rheumatoid arthritis, thrombophlebitis or deep venous thrombosis) [22][23][24][25], and/or cases having received at any time treatment with corticoid or hyaluronic acid injections, cognitive or communicative impairment or being involved in a medical-legal dispute at the time. To avoid possible significant changes in the study, patients were asked to maintain their usual physical activity and treatments throughout the study, but they were allowed to use paracetamol; however, drug intake data was recorded to monitor any possible influence on final measurements.…”

Treatment of Patellofemoral Pain Syndrome with Dielectric Radiofrequency Diathermy: A Preliminary Single-Group Study with Six-Month Follow-Up

Background and Objectives: Notwithstanding patellofemoral pain syndrome (PFPS) being one of the most common causes of pain in the front of the knee in outpatients, few studies have shown the effects of radiofrequency on knee pain and function in this population. The aim of the present study was to determine whether outpatients diagnosed with PFPS obtained improvement in pain and function after treatment by dynamic application of monopolar dielectric diathermy by emission of radiofrequency (MDR). Materials and Methods: An experimental study was conducted with 27 subjects with PFPS. Subjects were treated with 10 sessions of MDR in dynamic application. The visual analogue scale (VAS), the Kujala scale, the DN4 questionnaire, the lower extremity function scale (LEFS), the range of movement (ROM) in knee flexion and extension and the daily drug intake were measured pre- and post-intervention and at the time of the follow-up (six months). Results: Statistically significant differences were found in pain perception (VAS: F1,26 = 92.43, p < 0.000, ŋ2 = 0.78 and DN4: F1.26 = 124.15, p < 0.000, ŋ2 = 0.82), as well as improvements in functionality (LEFS: F1.26 = 72.42, p < 0.000, ŋ2 = 0.74 and Kujala: F1.26 = 40.37, p < 0.000, ŋ2 = 0.61]) and in ROM (Flexion: F1.26 = 63.15, p < 0.000, ŋ2 = 0.71). No statistically significant changes in drug intake were found. Conclusions: The present study shows that the dynamic application of MDR seems effective in reducing pain and increasing functionality and knee flexion in patients with PFPS, after a follow-up of six months.

“…This technique consists of the application of two adhesive electrodes on the skin that transmit low frequency electric stimulation to reduce pain by the control gate mechanism [18][19][20]. However, other non-invasive techniques seem effective in pain treatment, such as dielectric transmission radiofrequency [21]. This procedure allows energy to be transferred non-invasively to deeper tissues than with conventional electrotherapy or thermotherapy systems [22].…”

Monopolar dielectric radiofrequency (MDR) is a non-invasive treatment for pain based on the local application of electromagnetic signals. The study’s goal was to analyze the effects of MDR on the symptoms of fibromyalgia. For this aim, a randomized controlled trial was conducted on 66 female participants (aged 47 ± 17.7) diagnosed with fibromyalgia. Participants were randomly allocated to either an experimental group (n = 23), which received eight 20-minute sessions of MDR; a sham group, which received the same number of sessions of a sham MDR therapy (n = 22); or a control group (n = 21), which received usual care. The outcome variables included pain measured by the visual analogue scale (VAS), score on the hospital anxiety and depression scale (HADS) and quality of life measured by the combined index of fibromyalgia severity (ICAF). A large effect size was observed for the local pain (R2 = 0.46), total ICAF (R2 = 0.42) and ICAF physical factor scores (R2 = 0.38). Significant mean differences were found for the local pain (p = 0.025) and ICAF physical factor (p = 0.031) scores of the experimental group in comparison with the sham group. No statistically significant differences between groups were found in HADS. In conclusion, MDR is more effective than either sham treatment or usual care in the short-term improvement of pain and the physical wellbeing of participants with fibromyalgia.
