Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention consists in intravaginal electrical stimulation using Neurotrac™Sport XL, which is a dual channel stimulador with the reduced pulse width. 50 – 330 µS. The physiotherapist programs the device with the follow parameters: frequency:=25 Hz; pulse duration= 330 us; time= 20 min; 20-s on/40-s off cycles.
The intervention is carried out daily during 9 weeks at home by the subject, who inserts alone the intravaginal electrode, which is connecting with the device, and starts the session. One sesion a week under physiotherapist supervision in the hospital.
The adherence is monitored by a home-diary.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients are derived from Multiple Sclerosis's Unit of Virgen Macarena University Hospital and , then randomly assigned to an intervention group (I) or control group (II). The method of allocations is a central randomisation by phone/fax/computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The method used to generate the sequence is “MAS Version 2.1 @Glazo Wellcome.”
This program did a randomized block: A/B.
Block design: AABB
Block size: 4

Summary
Brief summary
Lower urinary tract dysfunction affects 50-90% of people with Multiple Sclerosis at some stage through the course of the disease. It is a serious medical condition with a severe social impact, causing embarrassment and negative self-perception. Urinary incontinence can be treated with: conservative or pharmaceutical intervention, surgery or pelvic floor muscle trainig (PFMT). PFMT may consist of exercises or intravaginal electrical stimulation. The aim of this study is evaluate the effects of this intervention on patients with Multiple sclerosis. This is an experimental trial with a sample of 60 subjects. Each subject is randomized assigned to the experimental group or to the control group. The experimental group receives the treatment: a home-dairy session of 30 minutes’ intravaginal electrical stimulation with Neurotrac ™ during 9 week. The control group receives no treatment. The outcomes are: power and endurance of pelvic floor measured by with Neurotrac ™ETS; urinary leakages measured with a week- bladder diary and quality of life measured with MusiQoL and SF-36 questionnaire. Data are registered before and after the intervention with a 3-month follow-up.
