Brief Summary

The aim of the study (OVERACT_V1) is to verify if the isometric contraction of ankle plantarflexor and Hamstring muscles, induces a significant reduction of overactive bladder symptoms in patients with Multiple sclerosis.

Detailed Description

The aim of the study (OVERACT_V1) is to verify if the isometric contraction of ankle plantarflexor and Hamstring muscles, induces a significant reduction of overactive bladder symptoms in patients with Multiple sclerosis. It's known that the electric stimulation of the Posterior Tibial nerve induces an improvement of overactive bladder symptoms through a modulation of spinal circuitry, which occurs with unknown mechanisms. The investigators' hypothesis is that the voluntary muscular activation may induce a modulation of the sacral root as long as the electric stimulation. 30 patients will be recruited within 2 years, since October 2017 through October 2019. This is a monocentric, randomized controlled , in single blind, not pharmacological study.

Primary Outcome Measures
NameTimeMethod
Change of Urinary frequencyat 6th and 22nd day

mean of voluntary urination episodes daytime during 4 days of bladder diary

Change of Urge scoreat 6th and 22nd day

mean of score evaluating the perception of urge that patient experiences every urination. The subscale scores are:

* 0, if patient doesn't need to urinate, but urinates before going out from home or concerned about the unavailability of toilet;

* 1, if patient doesn't experience urgent urination;

* 2, presence of urgency but disappeared before getting to the toilet;

* 3, presence of urgency and reached the toilet without leakage of urine

* 4, presence of urgency and did not reach the toilet with leakage of urine

Change of total score of OAB-q ( Overact Bladder questionnaire) long format 3rd and 18th day

questionnaire evaluates the impact of overactive bladder symptoms on activities of daily living 8 ITEMS SYMPTOM BOTHER (each item has a subscale score from 1 to 6) + 25 ITEMS HEALTH-RELATED QUALITY OF LIFE (each item has a subscale score from 1 to 6)

Secondary Outcome Measures
NameTimeMethod
Change of Urine volumeat 6th and 22nd day

Minimum , maximum and mean of urine volume voiding during 4 days of bladder diary

Change of episodes of urinary incontinenceat 6th and 22nd day

Mean of involuntary leakage of urine during 4 days of bladder diary

Change of episodes of nocturiaat 6th and 22nd day

Mean of voluntary urination episodes nightime during 4 days of bladder diary

Change of Postvoid Residual Volumeat 3rd and 18th day

Mean of 3 measurement of Urine residual after voluntary voiding

Change of Pad-test 24 Hoursat 6th and 22nd day

Mean of numbers and weight of pads

Change of value at Uroflussimetryat 3rd and 18th day

Mean of maximum urinary flow rate (Qmax) value at uroflussimetry

PGI (Patient global impression of improvement)at 18th day

Questionnaire on subjective impression of improvement of overactive bladder symptoms

Change of value at "H REFLEX" testat 6th and 22nd day

Evaluation of H wave mean amplitude and of Ratio of maximum H reflex to maximum M response after a train of stimuli given at 1 and 0.1 Hz

Change of EDSS (Expanded Disability Status Scale)at 2nd and 22nd day

Mean of value at EDSS that quantifying disability in multiple sclerosis

Change of Barthel Index Scoreat 2nd and 22nd day

Mean of total score measuring performance in activities of daily living

Change of MAS (Modified Ashworth Scale )at 2nd and 22nd day

Mean of score (0-4) measuring spasticity of plantarflexors and Hamstring muscles
