NCT04573673

Brief Summary

The present trial is designed to assess the efficacy and safety of transcutaneous tibial neuro-stimulation (TTNS) in improving bladder emptying in multiple sclerosis (MS) patients. Patients presenting with MS and performing clean intermittent self-catheterization (CISC) to empty the bladder in the context of voiding dysfunction, will be eligible. Included patients will be randomly assigned to two distinct arms

  • PTNS de verum : patients will be treated with transcutaneous tibial neuro-stimulation at a rate of one session of 30 consecutive minutes daily for a period of 12 weeks.
  • PTNS placebo : Patients will be treated with placebo (i.e. no current) transcutaneous tibial neuro-stimulation for 30 consecutive minutes daily for a period of 12 weeks (same treatment regimen as the experimental group). Efficacy in improving voiding dysfunction will be assessed 12 weeks after randomization using the BVE ratio (Bladder Voiding Efficiency) = Ratio of urine volume / total bladder volume.

Outcome Measures

Primary Outcomes (1)

  • BVE ratio (Bladder Voiding Efficiency) = Ratio of urine volume / total bladder volume

    BVE will be measured during the multi-channel urodynamic study

    At 12 weeks after randomization

Secondary Outcomes (19)

  • Maximal flow rate (mL/s) on multi-channel urodynamic study

    At baseline, At 12 weeks after randomization

  • Post-void residual volume (mL) on multi-channel urodynamic study

    At 12 weeks after randomization

  • Maximal detrusor pressure during micturition (cmH2O) on multi-channel urodynamic study

    At 12 weeks after randomization

  • Mean voided volume (mL) on a three-day ambulatory measure

    At 12 weeks after randomization

  • Mean maximal flow rate (mL/s) on a three-day ambulatory measure

    At 12 weeks after randomization

  • +14 more secondary outcomes

Study Arms (2)

PTNS verum

EXPERIMENTAL

Patients will be treated with transcutaneous tibial neuro-stimulation with one 30-minute session daily for a period of 12 weeks.

Device: PTNS de verum

PTNS placebo

SHAM COMPARATOR

Patients will be treated with placebo (i.e. no current) transcutaneous tibial neuro-stimulation for 30 consecutive minutes daily for 12 weeks (same treatment regimen as the experimental group).

Device: PTNS placebo

Interventions

The device will be set to program P-4: Frequency 20Htz, Pulse duration = 200 µs. The amplitude (Volt) will be adjusted by the patient according to the feeling.

Also known as: Peristim Pro (CEFAR-COMPEX®)
PTNS verum

The device will be set to program P-4: Frequency 20Htz, Pulse duration = 200 µs. A resistor will be incorporated in the device to block the passage of electric current

Also known as: Peristim Pro (CEFAR-COMPEX®
PTNS placebo
