Pathophysiology remains largely unclear. Common treatment modalities show unsatisfactory results. This randomised controlled trial aims to establish the long-term effect of pelvic floor re-education using biofeedback and home training for men with CPPPS evaluated with the National Institute of Health\u2013Chronic Prostatitis Symptom Index (NIH-CPSI) and to explore if outcomes can be correlated to changes in objective urodynamic measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>After inclusion all study participants will go through baseline testing consisting of urodynamic evaluation, assessment of the pelvic floor muscles and the NIH-CPSI questionnaire, thereafter, randomised to intervention or control group. Intervention consists of short daily session of pelvic floor muscle training, during 6\u2009months. Parallelly with starting up, the intervention group will attend four bio-feedback sessions, to guide and facilitate the training. The training will initially aim on how to correctly activate and relax the pelvic floor muscles with functional enhancement further on. The control group will be offered to enter the intervention group after the 6-month assessment. The outcome will be assessed by repeating the baseline tests at 3, 6 and 12 months.<\/jats:p>\n                    <jats:p>To compare the primary outcome, the NIH-CPSI questionnaire between and within the two groups will be analysed. Secondary outcomes are the differences in sub-score reduction according to the domains in the NIH-CPSI questionnaire, the manual assessment of the pelvic floor muscles and numerical results from the urodynamic testing. The correlation between subjective and objective outcomes will be analysed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>The study obtained ethical approval from the Swedish Ethical Review Authority (2023-00286-01).
