Lumbosacral transcutaneous electrical stimulation in children with slow transit constipation: A pilot case series

Abstract

Background and aim: This prospective pilot case series evaluated the efficacy of lumbosacral transcutaneous electrical stimulation using interferential current (TESIC) administered with a portable interferential device in children with slow transit constipation (STC). Children with STC are often treatment resistant. TESIC has been successful in some cases. Numerous variations exist for TESIC, with respect to application site, frequency and current settings. This study evaluates an alternative method of TESIC in children with STC to that reported previously. Methods: Eight children with STC failing standard management were treated with TESIC. Treatment was applied to the lumbosacral region twice daily for 30 min for four weeks. Families used small, portable devices at home. TESIC was administered with two electrodes placed in the lower lumbar region and two placed over the gluteal muscles. Patients were monitored for four weeks before and after TESIC therapy. Results: Compared to baseline, there was a significant increase in the number of bowel movements (total and spontaneous) during TESIC therapy (p < 0.05; Wilcoxon signed ranks test). Most patients reported a non-significant improvement in abdominal pain. Similarly, there were non-significant improvements in post TESIC parental and children quality of life scores. Conclusion: This new method of TESIC for STC warrants further evaluation in a randomised, controlled trial.
