Introduction: In the treatment of patients with chronic pain, whole-body electrostatic therapy using the Elosan Cabin C1 has been proposed as an adjunctive therapy. So far, data on the use of this cabin are limited. Promising results with a significant reduction in pain scores have been obtained in a small group of patients. However, treatment with Elosan Cabin C1 has not been the subject of evaluation in a larger patient population. The aim of this study was to investigate the efficacy and adverse effects of electrostatic treatment in such a population.
Methods: Prospective, multi-center, observational clinical trial conducted in daily practice in a large adult ambulatory population with chronic pain. Each patient received eight weekly Elosan C1 treatment sessions for up to 9 weeks. Treatment was added to an established conservative pain management. Pain scores (visual analog scale (VAS) 0-100, primary outcome) and sleep quality (seven-point Likert scale, secondary outcome) were assessed before, during, and at the end of the treatment period; quality of life (SF-12: Physical Component Summary = PCS, Mental Component Summary = MCS; secondary outcome) was assessed before and at the end of the treatment period. Subgroup analyses were performed for sex, age, duration of pain, initial pain location, pain entity, and pain medication at the start of treatment.
Results: A total of 192 patients were enrolled, 143 patients (74.5%) had a complete set of 8 treatment sessions. A reduction in pain scores from 68 ± 14 points to 47 ± 22 points was observed (p < 0.001), 65% of patients (responders) had a reduction of > 15 points. Female patients had a significantly better response than male patients with a higher number of responders (76% vs. 38%; p < 0.001). Patients with a pain history < 1 year had a significantly better response than patients with a pain history > 1 year. The Physical Component Summary (PCS) increased from 36 ± 11 to 41 ± 11 (+ 18%, p < 0.001) and the Mental Component Summary (MCS) from 41 ± 7 to 43 ± 7 (+ 6%, p = 0.3). Overall sleep quality improved significantly from 4.6 ± 1.7 to 3.73 ± 1.7 points (p < 0.001), with a higher proportion of responders in the female group (37 vs. 18%; p < 0.034). No serious adverse events were observed during treatment.
Conclusions: Electrostatic therapy with Elosan Cabin C1 may be a useful and effective adjunct therapy for patients with chronic pain. The results suggest that female patients and those with a recent history of pain experience the greatest benefit.

Electrostatic treatment with the Elosan Cabin C1 is a form of pain therapy that works by applying an electrical charge to the outside of the whole body without a corresponding current flowing inside. The treatment is painless and lasts 8 min per session. The study investigated the effect of the Elosan treatment in 143 patients over a period of 8 weeks with sessions once per week. Investigated outcomes were changes in pain, quality of life, sleep quality, and side effects of the treatment. 65% of the patients had a relevant improvement in pain levels, the average pain reduction in all patients was 30.9%. Quality of life and sleep quality also improved significantly. There were no relevant side effects of the treatment. The best effect was seen in female patients and if the duration of pain was less than 1 year. It was found that by applying the electrostatic field once a week, various types of pain can be reduced with a long-lasting effect. The treatment is ideally combined with physiotherapy and other complementary pain therapies.
