Pelvic Pain

  • Sonographic Imaging and Electromyography 

    There is an urgent need to identify patients, before treatment begins, who are likely to respond positively to physical therapy. In collaboration with Shawn Roll, Ph.D., OTR/L, CWCE, we are combining sonography and electromyography (EMG) to obtain objective measures to enhance clinical screening to better identify CP/CPPS patients appropriate for physical therapy. We aim to identify a set of neuromuscular biomarkers for CP/CPPS patients using sonographic imaging and EMG recording, and to determine the ability of neuromuscular biomarkers to enhance current clinical phenotyping. This cross-sectional study will acquire sonographic images and EMG recordings from the pelvic floor in a cohort of 20 patients with CP/CPPS and 20 controls. Analysis of multiple innovative sonographic techniques (i.e. 2D and 3D, spectral analysis, and elastography) and EMG recordings will identify important biomarkers of CP/CPPS. When combined with current clinical subjective measures, these biomarkers will lead to the development of a new methodology for use in screening CP/CPPS patients. Future studies will utilize the outcomes of this project to enhance the effectiveness of physical therapy for CP/CPPS through clinical implementation of sonographic/EMG screening and the evaluation of treatment outcomes based on sonography/EMG measures. This work is funded by a pilot grant from the USC Southern California Clinical and Translational Science Institute.

    Cortical Control of the Pelvic Floor Muscles in Healthy Adults: A Repetitive Transcranial Magnetic Stimulation (rTMS) Study 

    This study is about the pelvic floor and urologic chronic pelvic pain syndromes (UCPPS). We hope to learn how the brain controls pelvic floor muscles and other associated muscles in healthy adults, and in adults with diagnosed UCPPS, by using repetitive transcranial magnetic stimulation and electromyography.

    Transcranial magnetic stimulation (TMS) is the non-invasive stimulation of the brain by a magnetic coil on the surface of the head. Repetitive transcranial magnetic stimulation (rTMS) involves repetitive TMS stimulations. Electromyography (EMG) uses special metallic sensors on the surface of the skin to detect electrical activity that muscles generate.

    You may be eligible to participate if you are:

    • At least 18 years old
    • Without chronic pain or other conditions of the pelvic floor, OR
    • Diagnosed with one or more urologic chronic pelvic pain syndromes

     If enrolled in the study, you will be paid $50 for your time in completion of this study.
