Brief summary
The primary aims of this research are three folds: (1) To identify more relatively effective interventions for improving pain symptoms in CP/CPPS patients. (2) To ascertain the correlation between PFM elastic modulus and tenderness symptoms. This may find a more objective method of assessing efficacy. (3) To determine the correlation between the intensity of the sympathetic response and the patient's symptoms and to explore other possible pathogenetic mechanisms.
Detailed description
Chronic prostatitis/chronic pelvic pain syndrome is a high prevalent syndrome. Previous studies showed that extracorporeal shockwave therapy and myofascial release therapy could improve quality of life in patients with Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Theoretically, a combined therapy with extracorporeal shockwave therapy and myofascial release therapy is likely to have significant advantages in treating CP/CPPS.
Interventions
DEVICEextracorporeal shockwave
Patients will be treated with extracorporeal shockwave therapy (ESWT) with bladder lithotomy position, twice a week for 4 weeks, 3,000 individually with a maximum total energy flow density of 0.25 mJ/mm2, rate 3Hz each time. Extracorporeal shockwave (RUIDI.SWT001, Shenzhen, China) can provide a kind of physical spark wave energy, that will be delivered by the probe. The water sac probe will be moved slowly over the groin, perineum and crura of the penis.
BEHAVIORALmyofascial release
pressure was applied at 1 kg/cm2 (within the patient's tolerable range depending on the individual) to the points where patients had a VAS pain score of 4 or more during palpation. Intermittent pressure will be applied for 180-210s at the tenderness until the muscle relaxed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pelvic floor muscle surface electromyography changes | Assessments will be conducted before the intervention (T0), before the 5th intervention (T1), immediately after the 8th intervention (T2), and at the 4th week after the end of the 8th intervention (T3),assessing changes between these time points. | Pelvic floor muscle sEMG values will be collected using the Glazer pelvic floor muscle sEMG assessment (VISHEE SA9800) Pre-resting sEMG; Tense contraction phase sEMG; Endurance contraction phase sEMG; Post-resting EMG. |
| National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) changes | Assessments will be conducted before the intervention (T0), before the 5th intervention (T1), immediately after the 8th intervention (T2), and at the 4th week after the end of the 8th intervention (T3),assessing changes between these time points | Questionnaire with 13 entries, including 4 aspects: pain and discomfort symptom score, urinary symptom score, symptom impact score, quality of life score, with a total score of 0 to 43. The severity of CP/CPPS can be graded according to the total scores: mild (1-14), moderate (15-29), or severe (30-43). The efficacy evaluation criteria are developed with reference to the National Institutes of Health-Chronic Prostatitis Symptom Index score. Clinical control is defined as ≥ 90% decrease in the NIH-CPSI score; obvious improvement as ≥ 60% and \< 89% decrease; improvement as ≥ 30% and \< 59% decrease, and ineffective as \< 30% decrease. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Three-dimensional quantification and Shear Wave Elastography (SWE) changes | Assessments will be conducted before the intervention (T0) and at the 4th week after the end of the 8th intervention (T3),assessing change between two time points | Trans-rectal three-dimensional ultrasound (VOLUSON E8) will be used to assess the morphological parameters of the lacunae of the levator hiatus in CP/CPPS patients, the area of the levator hiatus is situated at a depth of 2-4 cm from the perineum, where is well within the effective range of 7-4-MHz transducers. |
| sympathetic skin response (SSR) changes | Assessments will be conducted before the intervention (T0) and at the 4th week after the end of the 8th intervention (T3),assessing change between two time points | SSR is a recently established method of non-invasive somatic neurography offers the advantages of both non-invasiveness and specificity, using the SA7550 FlexComp Infiniti System (Thought Technology, Canada). Sympathetic skin responses will be recorded with the active electrodes placed in the left palm and the reference electrodes on the dorsum of the left hand, while the patient will be in the sitting position. A channel recording from hand will be obtained simultaneously by stimulating the contralateral median nerve at the level of the wrist with a stimulation intensity at 20 mA for 0.2 ms\[29\]. A total of three potentials will be recorded and the mean values will be used for analysis. |
