“…Berry and colleagues showed that patient-reported improvement in symptoms, symptom score, and uroflow curves did not correlate with objective parameters of voided volume and PVR. 9 Similarly, van Gool revealed a mismatch between urodynamic patterns and clinical symptoms both before and after pelvic floor muscle retraining. 10 Likewise, Bartkowski et al found nearly a third of their studied cohort of asymptomatic children with no urologic history displayed increased EMG activity during voiding.…”

“…PFBT "Responders" were defined as patients demonstrating a change in pelvic floor EMG activity from inappropriately active during the voiding phase pre-PFBT to appropriately quiet during voiding following PFBT therapy. We analyzed symptom score questionnaires only if questions (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) were answered with an appropriate single answer. The primary outcome measures were quiescence of pelvic floor EMG activity and change in symptom scores over time.…”

Introduction: Pelvic Floor Biofeedback Therapy (PFBT) can be an effective treatment for pediatric lower urinary tract symptoms (LUTS). Due to differing perceptions of efficacy and practice patterns, we sought to further evaluate PFBT in our practice. We hypothesized that PFBT results in quiescence of EMG activity during voiding and improves questionnaire scores in patients with LUTS. Methods: We retrospectively reviewed all patients undergoing PFBT and refined the analysis to females ≥6 years old with ≥2 sessions with completed voiding questionnaires pre-and post-treatment, active EMG during voiding, with nonneurogenic urinary tract complaints refractory to standard urotherapy. Validated Bladder Bowel Dysfunction (BBD) questionnaires were collected at each visit.Quiescence of EMG activity and changes in BBD score were the primary outcomes. Results: 229 patients underwent ≥1 PFBT session, of which 64 females ≥6 years of age with ≥2 PFBT sessions and completed pre and post PFBT voiding questionnaires were identified. In this group, mean age at PFBT start was 10.1 (6.2-17.0). Patients completed 3.1 sessions (2-6). No difference was seen in post-void residual (PVR) between first and last session (23.8 vs 22.6 mL, P = 0.55). Median questionnaire score decreased from 18 (4-42) before to 13 (2-28) following PFBT (P < 0.0001).Responders, characterized by silencing of the EMG after PFBT, occurred in 31% (20/ 64). Non-responders were younger (P = 0.007) with higher pre-PFBT questionnaire scores. Conclusion: The use of PFBT appears to result in a significant reduction in symptom scores, though quiescence of EMG was observed following therapy in less than 1/3 of patients.

“…[9,14] Pelvic floor muscle training through biofeedback is a non-invasive, interactive urotherapy modality that teaches children how to control their lower urinary tract correctly with the goal of sustaining pelvic floor relaxation during voiding. [11] In biofeedback therapy, surface EMG electrodes are used to detect a change in skeletal muscle activity, which is then fed back to the user with a verbal or visual warning. Biofeedback therapy has been determined to be useful both as a musculoskeletal and neurological treatment modality.…”

“…Voided volume and total PVR were evaluated together as total bladder volume (TBV). [11] Age-adjusted normal bladder capacity (NBC) was calculated using the Koff formula [(age+2) x 30]. [12] As TBV was affected by the patient's age, TBV/NBC values were also calculated.…”

Objective: To investigate the effect of biofeedback therapy on children with desmopressin-resistant primary monosymptomatic enuresis (MsE). Material and methods:The study comprised both retrospective and prospective sections. A total of 262 medical files of patients who were diagnosed as enuresis between November 2012 and January 2015 were retrospectively screened. Patients with neuropathic bladder, daytime voiding problems, anatomical pathology and enuresis-related diseases were excluded from the study. The demographic data and family characteristics of 29 children with desmopressin-resistantprimary MsE were recorded. After biofeedback treatment patients whose frequency of enuretic episodes decrease by more than 50% were included in the successful biofeedback treatment group (SBTG), while other patients were categorized in the unsuccessful biofeedback treatment group (USGBT). The outcomes of uroflowmetry, voided volume, postvoiding residue (PVR) and total bladder volume/age-adjusted normal bladder capacity (TBV/NBC) were recorded before and at the sixth month of the treatment.
