Biofeedback treatment of bladder dysfunction in multiple sclerosis. A randomized trial.

Fifteen women and five men with bladder dysfunction due to multiple sclerosis were randomized to plus/minus biofeedback using bladder pressure and simultaneous EMG registration via surface electrodes. All the patients had behavioural modification, pharmacological adjustment and pelvis floor training. The number of incontinence episodes decreased and maximal cystometric capacity increased, while first sensation and pad test were unchanged. Subjective treatment results assessed by visual analogue scales for incontinence and obstrusive voiding symptoms were highly significant. However no biofeedback parameter was improved and no difference could be demonstrated between the two treatment groups. In conclusion the used biofeedback technique is insufficient and the 60 min. standardized pad weighing test is inadequate in this type of patients.
