Evaluation of the Link Between Bladder Sensation and Changes in Skin Electrical Conductance and Heart Rate. - Full Text View

Purpose

Measuring sympathetic skin response or heart rate variability can provide an objective biomarker of bladder sensation and its modulation by drug with potential to treat overactive bladder.

Official Title:	Evaluation of Sympathetic Skin Responses and Heart Rate Variability as Objective Measures of Bladder Sensation - a Double Blind Third Party Open Placebo Controlled Randomised Study Using a Single Dose of Tolterodine in Patients With Idiopathic Overactive Bladder and Healthy Volunteers

Further study details as provided by Pfizer:

Primary Outcome Measures:

Heart rate variability evoked by filling cystometry and intravesical neurostimulation and sympathetic skin response evoked by intravesical neurostimultion in healthy volunteers and OAB patients [ Time Frame: Duration of study. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To investigate the correlation between the changes in heart rate variability and sympathetic skin response evoked by filling cystometry and intravesical neurostimulation in OAB patients. [ Time Frame: duration of study ] [ Designated as safety issue: No ]
To determine whether there is a difference in the stimulus response relationship for the evoked changes in HRV and SSR between healthy volunteers and OAB patients. [ Time Frame: duration of study ] [ Designated as safety issue: No ]
