A shortened 6-week treatment with PTNS appears to be successful, with a significant reduction in symptoms and improvement in HRQL. This early data suggest that the duration of treatment for peripheral neuromodulation can be halved compared with the conventional 12 weeks, which would make it more acceptable and cost effective for patients. A randomised controlled trial of 6 weeks vs 12 weeks of PTNS therapy would be useful in determining the optimal duration of treatment.
Women receiving PTNS for intractable OAB syndrome reported significant symptom relief at 2 years. This remains a safe mode of second-line treatment with excellent durability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
