Impact of TTNS on Bladder Symptoms Among People With MS, A RCT
Sponsor: Hawra Al-Dandan
Summary
Background: Neurogenic lower urinary tract dysfunction is common among people with multiple sclerosis (MS). Recent studies showed that bladder storage symptoms are predominant among MS with a pooled prevalence of frequency at 73.45% followed by urgency at 63.87%. Transcutaneous tibial nerve stimulation (TTNS) is a non-invasive treatment to manage bladder storage symptoms; however, the effectiveness of TTNS is based on a small number of studies with the absence of high-quality evidence. This study aims to investigate the effectiveness of TTNS on bladder storage symptoms compared with sham TTNS among people with MS.Methods: The investigators will use a randomised sham controlled double blind study to explore the effectiveness of TTNS in the treatment of bladder storage symptoms in MS. the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) was followed to standardize the conduct and reporting of the current protocol. The recruitment plan is twofold: 1) Open recruitment for people with MS through King Fahd Hospital of the University communication channels; 2) people with any type of MS attending their routine appointments in MS clinic at King Fahd Hospital of the University, Al Khobar. The investigators will investigate the effectiveness of TTNS compared to sham TTNS on bladder storage symptoms and the effect on quality of life using ICIQ-OAB, ICIQ 3-day bladder diary, ICIQ-LUTS qol, and PSQI. Participant's perception of change post intervention will be evaluated using GPE. Outcomes will be measured at 0, 6 weeks and at 6 months post intervention. A sample size of 72 patients (36 in each group) is required to achieve 90% power with two-tailed tests at an alpha level of 0.05. Conclusion: Multiple sclerosis is a long-term condition, and self-management is important. TTNS provide a safe, non-invasive intervention that can be administered at home. Should the trial determine that TTNS is effective compared to sham TTNS, the investigators will plan to integrate TTNS into standard clinical care pathways in MS.

Interventions
Active Transcutaneous Electrical Nerve Stimulation (TENS)
For active group: Participants will useTENS to stimulate tibial nerve on the medial side of the foot for 6 weeks, a total of 18 sessions, three times weekly for 30 minutes per session. All TENS units will be programmed and locked by principal investigator to ensure fixed stimulation parameters are used among participants throughout the study intervention. The stimulation frequency will be set at 10 Hz with a pulse duration 200 μs. The stimulation is proved by flexion of the big toe (motor response) and/or tingling sensation of ipsilateral sole of foot (sensory response) by raising the current amplitude, mA, intensity. Increasing the intensity above sensory threshold is recommended but should not be painful
Sham Transcutaneous Electrical Nerve Stimulation (TENS)
TENS on the lateral side of the foot, the negative electrode on the top of the foot just above the small toe for conduction and the positive electrode on the bottom of below the smallest toe to avoid the tibial nerve and relevant cutaneous nerves. Participants will be instructed to raise up the intensity until the first and slight tingling sensation on the sole of the foot or toe
