PURPOSE

Neuromodulation is recognised treatment for idiopathic bladder overactivity (OAB) in children. However, there is no

strong evidence about the best frequency to use with both high and low frequencies demonstrating effect. High

frequencies (over 20 Hz) are reportedly associated with worsening of symptoms due to excitement of the neuromotor

system (Lordelo et al. The Journal of Urology 2009;182 (6):2900-4).

The purpose of the study was to compare two different frequency programmes to determine which was the most

effective.

MATERIAL AND METHODS

A retrospective, non-randomized trial was performed in children referred to our tertiary referral centre with idiopathic

OAB. Patients were treated with a TENS machine applied to the parasacrum for 40-60 mins/day for 12 weeks. The

patients were divided into 2 groups: group 1 used a frequency of 10Hz and group 2 a frequency of 80Hz (pulse width

200μs,, mA maximum tolerated per session.) Data regarding days completed, time used, complications/problems and

symptoms were recorded and assessed against ICCS criteria.

RESULTS

A total of 204 patients were recruited; 138 (68%) patients in group 1 and 66 (32%) in group 2. The overall response

rate was 54%.

Results are shown in the table.

CONCLUSIONS

TENS is successful in the treatment of idiopathic OAB but there is no significant difference in response rate and

complications between two frequencies (10 Hz, 80Hz). Further studies are needed in order to identify the optimal

frequency and placebo effect.
