Literature review on noninvasive central nervous system (brain and spinal cord) stimulation to improve bladder and pelvic floor function in the aging population

Abstract

Purpose of review The literature was reviewed for all noninvasive central nervous system (CNS) stimulation techniques, which includes transcranial brain or trans-spinal stimulation, in the aging population. Given the rising ubiquity of this technology, noninvasive nature, and low side-effect profile reported, this technology can have a big impact on the aging population. As patients afflicted with neurogenic disorders are living longer lives, a special emphasis is placed on the aging neurogenic population. Recent findings Noninvasive CNS stimulation techniques have been applied to major bladder and pelvic floor disorders such as voiding dysfunction, chronic pelvic pain, urgency and urge incontinence, lower urinary tract dysfunction, and situational urge incontinence in both the idiopathic and neurogenic populations. Overall, these noninvasive technologies demonstrate effectiveness for the treatment of these conditions with some studies showing effectiveness with longer-term follow-up suggesting lasting CNS remodeling. Summary Most manuscripts had a generally small number of patients and an even smaller number of geriatric patients represented. No studies were specifically designed to investigate geriatric outcomes. It is the hope of this systematic review to help model future studies according to existing literature, but with a focus on the geriatric population as they stand to gain the most from noninvasive technologies with limited adverse events.
