A Science Daily news report indicates new research finds repetitive sacral root magnetic stimulation can reduce the frequency of nighttime bedwetting and improve quality-of-life for sufferers.
In a study conducted by researchers at the Assiut University Hospital, Assiut, Egypt, 41 patients experiencing nocturnal enuresis were divided into two groups receiving either real magnetic stimulation or a sham stimulation using the same equipment and procedures. The identities of the real vs. sham patients were unknown to both the researchers and the patients. Each participant received 10 sessions, five per week. A magnetic stimulator was placed over the sacral vertebrae in the lower back and 15 Hz pulses were applied for 10 seconds on and 30 seconds off. For the sham procedure, the stimulator was internally adjusted so that little magnetic stimulation could reach the underlying tissue. All patients had been taking the tricyclic antidepressant drug imipramine (25mg once at night /day) for at least three months without satisfactory results and they continued taking their prescribed medication throughout the study.
“It seems likely that rSMS produced some of its effect in the present patients by a direct effect on bladder control,” explained lead investigator Eman M. Khedr, MD, Professor, Department of Neurology, Assiut University Hospital. “In the present study rSMS could have increased arousal or enhanced inhibition of neuronal re-uptake of noradrenaline and serotonin. We have previously reported that patients with nocturnal enuresis have pathologically increased excitability and reduced inhibitory processing in the motor cortex and it is possible that rSMS could affect these measures as well.”
