Brain and Pelvic Floor Muscle Activity of Patients Who Had or Are Undergoing Robot-Assisted Radical Prostatectomy

Investigating the Correlation Between the Brain and Pelvic Floor Muscle Activity of Patients Who Had or Are Undergoing Robot-Assisted Radical Prostatectomy

This trial investigates brain and pelvic floor muscle activity in patients undergoing robot-assisted radical prostatectomy. This trial may help identify the brain waves that are associated with muscles involved in giving patients control over the bladder.

Study Overview

• Status: Recruiting
• Conditions: Prostate Carcinoma
• Intervention / Treatment: Other: Questionnaire Administration; Procedure: Electroencephalography; Procedure: Electromyography; Procedure: Urodynamics (UDS)

Detailed Description

PRIMARY OBJECTIVES:

• Identify pelvic floor muscle (PFM) activity on electromyogram (EMG) and electroencephalography (EEG).
• Identify any synchrony in EMG and EEG for PFM activity.
• Identify any relationship between EEG activity and UDS findings.

SECONDARY OBJECTIVES:

I. Identify changes in EEG and EMG activity with Kegel exercise. II. Examine relationship between EEG activity and continence.

EXPLORATORY OBJECTIVE:

I. Examine feasibility of replacing EMG with EEG monitoring for muscle activity.

OUTLINE:

Patients perform standard of care Kegel exercises while undergoing brain and muscle activity monitoring by EEG and EMG and UDS, respectively, before surgery, 6 weeks after surgery, 3,months after surgery and 6 months after surgery.. Patients complete questionnaires over 5-10 minutes about urinary function.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
EEG measures obtained during urination.	Recordings of brain and muscle activity will be collected during urination	Up to 6 months after surgery
Pelvic floor muscle (PFM) EEG measures	Simultaneous recordings of brain activity using electrodes attached to the scalp and muscle activities of muscles of the anal sphincter with electrodes bonded to the skin.	Up to 6 months
Identification of Areas of synchrony in EEG Patterns and associated Urodynamics (UDS) findings	UDS data of Incontinence/continence will be monitored along with EEG recordings of brain activity during urination.	UP to 6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
EEG and EMG biofeedback	Patients will perform Kegel exercises while brain and muscle activity are monitored using a 128-channel EEG headset and up to 24 channel EMG system	Up to 6 months
Improvement of continence	International Prostate Symptom score - an 8 question screening tool -with a score from 0= never experienced to 5= almost always experienced.	Throughout life of study up to 6 months after surgery
