Chronic pelvic pain syndrome(CPPS)/chronic prostatitis IIIB are complex conditions characterized by pelvic pain, dysuria, and reduced quality of life.
Traditional treatment methods (medical therapy, physical therapy) are not always effective, requiring the search for new approaches.
Extracorporeal electromagnetic stimulation (ES) is an innovative method that affects the neuromuscular system and blood circulation of the pelvis.
- To evaluate the effectiveness of ES application in men with chronic pelvic pain syndrome/prostatitis IIIB. 
- To study the dynamics of NIH-CPSI (National Institutes of Health Chronic Prostatitis Symptom Index) questionnaire indicators before and after the treatment course.

37 men aged 25 to 55 years with diagnosed CPPS/chronic prostatitis III B.
 Inclusion criteria:
 -Presence of CPPS for more than 3 months, absence of infectious process confirmed by laboratory tests.

 Patients received ES treatment at a frequency of 2 sessions per week, 10 sessions total. The duration of one session was 20 min.
The procedure was performed on the Salus Talent Pro device, power 3 Tesla.
The mechanism of action is explained by the peculiarity of the nervous system response, so at a frequency of 1-4 Hz (tetta rhythm) in the stage of deep sleep there is myorelaxation of all muscles. Using this mode, we depress the nervous system and achieve myorelaxation.
NIH-CPSI questionnaire before and after treatment was used to evaluate the result of the treatment.
 The NIH-CPSI assesses three main parameters: 
      - Pain symptoms (scale from 0 to 21 points).
     - Dysuria symptoms (scale from 0 to 10 points).
     - Quality of life (0 to 12 point scale).

Statistical analysis: - Using Student's paired t-test.

Level of significance: p < 0.05.

Results Dynamics of NIH-CPSI scores:
   Before treatment: 
     - NIH-CPSI total score: mean 28.5 ± 3.2.
     - Pain symptoms: 16.8 ± 2.5.
     - Dysuria symptoms: 7.5 ± 1.2.
     - Quality of life: 9.2 ± 1.8.

   Post-treatment: 
     - NIH-CPSI total score: mean 12.3 ± 2.8 (p < 0.001).
     - Pain symptoms: 7.2 ± 1.8 (p < 0.001).
     - Dysuria symptoms: 3.1 ± 0.9 (p < 0.001).
     - Quality of Life: 4.5 ± 1.1 (p < 0.001).

Overall treatment efficacy:
    - A positive  was observed in 85% of patients.
   - A moderate effect without a complete disappearance of the symptoms was observed in 15% of the patients.

Mechanisms of action of ES:
  - Improvement of microcirculation in the pelvic organs.
  - Reduction of muscle spasm and normalization of pelvic floor muscle tone.
  - Stimulation of the nervous system produces antidepressant and analgesic effects.

Advantages of the method: 
  - It is non-invasive and has no side effects.
  - Possibility of use in combination with other methods of treatment.

Extracorporeal electromagnetic stimulation is a highly effective method of the treatment for men with chronic pelvic pain/chronic prostatitis IIIB. Significant reduction in NIH-CPSI scores confirms the positive effect of ES on pain symptoms, dysuria and quality of life of patients.
As part of the complex therapy of chronic prostatitis IIIB, the introduction of ES into clinical practice is recommended.
