Efficacy and safety of non-invasive low-frequency tibial nerve stimulator in overactive bladder

Abstract Objectives To evaluate the efficacy and safety of a non-invasive low-frequency tibial nerve stimulator (TNS-01) vs sham control in relieving the symptoms of overactive bladder (OAB) patients. Patients Participants who were diagnosed with primary OAB or exhibited at least one OAB symptom. Al...

description Abstract Objectives To evaluate the efficacy and safety of a non-invasive low-frequency tibial nerve stimulator (TNS-01) vs sham control in relieving the symptoms of overactive bladder (OAB) patients. Patients Participants who were diagnosed with primary OAB or exhibited at least one OAB symptom. All participants underwent three 30-min intervention sessions weekly. Methods The subjects were 1:1randomized (block randomization with a block size of 4) to either active treatment (TNS-01 group) or sham treatment (sham group). Based on the randomization, the subject will be given either an active or sham device system (systems will only differ in the Instructions for Use and electrode size/shape). During the 12-week study period, all participants underwent three 30-min intervention sessions weekly. The primary endpoint was the change in Overactive Bladder Symptom Score (OABSS) at week 12 from the baseline. Results Of the 109 recruited OAB patients. In the TNS-01 group, the OABSS change from baseline at week 12 was significantly higher than that in the sham group (2.83 ± 2.53 vs 1.62 ± 2.59, p = 0.02). The absolute and percent changes of average UUI episodes per day from baseline at week 8 in the TNS-01 group were significantly lower from those in the sham group (0.11 ± 1.33 vs 0.68 ± 2.14, p = 0.01; − 27.82% ± 167.33% vs 87.18% ± 25.20%, p = 0.04). One treatment-related adverse event (hematuria) was reported by one patient (1.8%) in the sham group. Conclusions The TNS-01 device is effective and safe in relieving OAB symptoms after 12 weeks of stimulation. Trial registration number: NCT04999657.
