“…In a clinical trial carried out in 2010 on 26 patients, it was found that biofeedback better improves bowel symptoms and anorectal function compared to standard therapies such as diet, exercise, and laxatives in patients with dyssynergic constipation (Rao, Valestin, Brown, Zimmerman, & Schulze, 2010). In another study on 52 patients with fecal incontinence, biofeedback had positive results in improving patients' symptoms and quality of life (Leite & Lacerda-Filho, 2013). Also, Ahadi et al have concluded that patients with dyssynergic constipation with and without IBS will likely benefit from pelvic floor biofeedback (Ahadi et al, 2014).…”

Purpose of the study: Pelvic floor muscles dysfunction is one of the most important etiologies of coccydynia, therefore, manual therapies have been proposed as the first line of treatment. The purpose of this study was to investigate the effect of biofeedback as a new approach in the treatment of coccydynia. Methods: Thirty women were randomized into two groups. Both groups were injected with corticosteroid. One group received pelvic floor muscle exercises plus biofeedback while the other only performed exercises. Patient’s pain was measured using Visual Analogue Scale (VAS) in the first visit and after 1, 2 and 6 months of follow-up as well as Dallas pain and SF-36 quality of life questionnaires before and 2 months after the treatment. Results: Pain had improved significantly after 1, 2 and 6 months in both groups compared to the baseline. However, the amount of change was not different between the groups at any time interval. The results were the same for Dallas pain scale and SF-36 quality of life questionnaire. Conclusion: Adding biofeedback to pelvic floor muscle exercises did not lead to any further improvement in management of chronic coccydynia. Further studies with larger sample sizes may show the effect of biofeedback more clearly.

“…It is worth noticing that wavelet packet decomposition provides numerous effective signal decomposition forms. As shown in Figure 6, an effective signal decomposed form consists of W 1 0 ∩ W 1 1 , W 2 0 ∩ W 2 1 ∩ W 1 1 , W 2 0 ∩ W 2 1 ∩ W 2 2 ∩ W 2 3 , etc. Assume that G = { G 1 , i = 1,2,3,…} is the set of all the effective decomposed forms.…”

“…The value in each subspace is the DB index value of the subspace. The colored subspace is the optimal wavelet packet basis based on DB index, that is W 2 0 , W 3 2 , W 3 3 , W 3 4 , W 3 5 and W 2 3 . Based on the subspaces corresponding to the selected optimal wavelet packet basis, the MEA j, p and P j, p which are not belong to the subspaces from feature vector M and N are removed.…”

“…Fecal incontinence not only brings physical and mental sufferings to patients, but also seriously affects patients’ orthobiosis and work (1). Traditional therapeutic methods such as biofeedback (2, 3), sacral nerve stimulation (4, 5), colostomy, and ileostomy (6, 7) can treat fecal incontinence to some degree, however, with limited success.…”

Assessment and in vitro Experiment of Artificial Anal Sphincter System based on Rebuilding the Rectal Sensation Function

et al. 2014

In this paper, a novel artificial anal sphincter (AAS) system based on rebuilding the rectal sensation function is proposed to treat human fecal incontinence. The executive mechanism of the traditional AAS system was redesigned and integrated for a simpler structure and better durability. The novel executive mechanism uses a sandwich structure to simulate the basic function of the natural human anal sphincter. To rebuild the lost rectal sensation function caused by fecal incontinence, we propose a novel method for rebuilding the rectal sensation function based on an Optimal Wavelet Packet Basis (OWPB) using the Davies-Bouldin (DB) index and a support vector machine (SVM). OWPB using a DB index is used for feature vector extraction, while a SVM is adopted for pattern recognition.Furthermore, an in vitro experiment with the AAS system based on rectal sensation function rebuilding was carried out. Experimental results indicate that the novel executive mechanism can simulate the basic function of the natural human anal sphincter, and the proposed method is quite effective for rebuilding rectal sensation in patients.

“…Instrumented anorectal biofeedback (BF) is an important component of the management algorithm and improves symptoms and quality of life in both patients with faecal incontinence and patients with defecation disorder-associated constipation. 4,5 Other options for management, such as surgery or sacral nerve stimulation for FI, are much more expensive, invasive and have significantly higher complication rates.…”

Background:Instrumented anorectal biofeedback (BF) improves symptoms and quality of life in patients with faecal incontinence and defecation disorder-associated chronic constipation. However, demand for BF greatly outweighs availability, so refinement of the BF protocol, in terms of the time and resources required, is of importance. Our aim was to evaluate the outcomes of an abbreviated BF protocol in patients with defecation disorder-associated chronic constipation and/or faecal incontinence compared to standard BF.Methods:Data were collected from consecutive patients (n = 31; age 54 ± 15; 29 females; 61% functional constipation) undergoing an intentionally abbreviated BF protocol, and compared in a 1:2 ratio with 62 age, gender and functional anorectal disorder-matched control patients undergoing a standard BF. Outcomes included change in symptoms, physiology, patient satisfaction and quality of life.Results:On intention to treat, patients in both protocols showed significant improvement in symptom scores and the magnitude did not differ between groups. Impact on quality of life, satisfaction and control over bowel movements improved in both protocols, but satisfaction improved to a greater extent in the standard BF protocol (p = 0.009). Physiological parameters were unchanged after BF apart from improvement in rectal sensation in the standard BF group compared to abbreviated BF (p ⩽ 0.002).Conclusions:Abbreviated anorectal BF offered to patients travelling from far away was not different to a standard BF in providing substantial, at least short term, improvements in symptoms of constipation and faecal incontinence, quality of life and feeling of control over bowel movements. Refinement of the standard BF protocol according to individual patient phenotypes and desired outcomes warrants further study in order to maximize efficacy and improve access for patients.
