Aim: To search in retrospectively and prospectively from the efficacy of biofeedback training in patients with fecal incontinence and to investigate the determinant factors of improvement of the patients.
Methods: The incontinent patients were evaluated in phases: I: In 37 subjects, 14 men and 23 women, aged between 13 and 82 years, biofeedback training was done, and the efficacy was determined retrospective form. II: In 14 patients, 2 men and 12 women, aged between 19 and 79 years, biofeedback training was done, and rectal balloon sensitivity, force of contraction and motor/sensitivity index were evaluated in prospective form before and after biofeedback training.
Results: In the group of the patients studied in phase I, findings were: 21 patients (60%) complete continence, 12 (34%) improvement, and 2 (5.7%) without change. In the group of the patients studied in phase II, findings were: 8 patients (57%) complete continence, 4 (29%) improvement and 2 (14%) without change. In patients with complete continence there was a decrease in rectal balloon sensitivity (P < 0.05) and an increase of the motor/sensitivity index (P < 0.05), before and after biofeedback training.
Conclusion: Biofeedback is a simple, painless and effective treatment for patients with fecal incontinence. It allows to improve rectal sensitivity and to increase the motor/sensitivity index, determinant for patients continence.

This study provides preliminary evidence for real-time functional magnetic resonance imaging neurofeedback (rt-fMRI NF) as a potential intervention approach for internet gaming disorder (IGD). In a preregistered, randomized, single-blind trial, young individuals with elevated IGD risk were trained to downregulate gaming addiction-related brain activity. We show that, after 2 sessions of neurofeedback training, participants successfully downregulated their brain responses to gaming cues, suggesting the therapeutic potential of rt-fMRI NF for IGD (Trial Registration: ClinicalTrials.

Objective: To evaluate the clinical efficacy of bladder function training combined with pelvic floor biofeedback electrical stimulation in the treatment of neurogenic bladder and its impact on urodynamics.
Methods: This was a clinical comparative study. A total of 120 patients with neurogenic bladder after spinal cord injury admitted to Beijing Rehabilitation Hospital of Capital Medical University and Beijing Shijingshan Hospital from January 2023 to December 2023 were randomly divided into two groups (n= 60/group).

Anorectal manometry (ARM) is a diagnostic test that utilizes pressure sensors to dynamically measure intraluminal anal and rectal pressures, thus providing an objective evaluation of anorectal functional parameters (tone, contractility, and relaxation), coordination and reflex activity, and sensation. ARM is a useful test for numerous indications including for the assessment and management of functional anorectal disorders such as fecal incontinence, functional defecatory disorders, and functional anorectal pain, preoperative assessment of anorectal function, and in facilitating/assessing response to biofeedback training. In addition, while many functional anorectal disorders present with overlapping symptoms (ie constipation, anorectal pain), ARM allows delineation of more specific disease processes and may guide treatment more effectively.

Heart rate variability biofeedback (HRV BF) training aids adaptation to new climatic, geographical, and social environments. Neurophysiological changes during the HRV BF in individuals from tropical regions studying in the Arctic are not well understood. The aim of this study was to research electroencephalographic (EEG) changes during a single short-term HRV BF session in Indian and Russian students studying in the Russian Arctic.
