LUTD is a common problem in children that can result in wetting during the day and night, frequent and urgent urination and urinary tract infections. In a subset of children, LUTD is the result of dis-coordination between pelvic floor and abdominal muscles. These children tend to contract their pelvic muscles rather than relax them during voiding. This abnormal contraction results in bladder changes that can result in incontinence. In most cases, understanding how to contract and relax the pelvic floor and abdominal muscles can help reduce LUTD symptoms. Identifying and learning how to utilize the pelvic floor without abdominal muscle activation is one of the most powerful effectors of bladder function.
