The role and function of feedback
Andrea Utley in Motor Control, Learning and Development, 2018
Biofeedback is described as a technique that provides information about performance via a signal from an external source which is related to a physiological process (e.g. heart rate, brain activity, muscle activity). This enables performers to alter or improve their performance by using information provided by their own body; however, it must be presented in such a way that people do not become dependent upon it. Although the most common form of biofeedback is that which uses the activity of muscles, electromyography (EMG) can comprise visual, auditory or tactile information (Lauber et al. 2016). EMG feedback is commonly used in a clinical setting and has been shown to be effective in treating patients with a variety of motor difficulties; recent developments have meant that EMG biofeedback training devices can be used at home.
Biofeedback
Hilary McClafferty in Mind–Body Medicine in Clinical Practice, 2018
There are no particular risks or contraindications with biofeedback, although provider training specifications are less structured than with other mind–body therapies. It is incumbent upon the patient to be sure the biofeedback practitioner is properly trained and able to refer appropriately if needed. Variable training standards and programs may indirectly impact patient progress. Individuals must learn correct use of the modality, and some may need regular practice to maintain the physiologic benefits. Overdependence on technology is a potential risk, although, ideally, the patient learns to trigger their relaxation response independently and over time is able to minimize reliance on technology. The cost of equipment and access to appropriate therapies are also considerations, as is the financial impact if insurance does not cover services.
Integrative hyperthermia treatments for different types of cancer
Clifford L. K. Pang, Kaiman Lee in Hyperthermia in Oncology, 2015
The patient’s symptoms of nausea and vomiting disappeared after 1 week. The dosage was increased for chelation detoxification therapy three times a week for 6 consecutive weeks. Intravenous medical ozone saline injection was used for 2 consecutive weeks; systemic biofeedback therapy was used for 2 consecutive weeks. TCM and acupuncture remained unchanged. After 2 weeks, the patient’s mental condition was improved and his weight had increased to 52 kg; his blood routine was as follows: RBC 3.5 × 1012/L, Hb 105 g/L, and WBC 4.7 × 109/L. At that time, intravenous medical ozone saline was adjusted to EBOO for 18 treatments, and the hyperthermia was changed to the combination of whole-body medium-high temperature hyperthermia and local hyperthermia. The whole-body hyperthermia was conducted once every 2 weeks for a total of four times. Local hyperthermia was conducted 3 times a week and once every other day for a total of 27 times. Systemic biofeedback therapy was conducted 3 times a week and once every other day for a total of 27 times. Chelation detoxification was conducted simultaneously with hyperthermia. Acupuncture was continued as in the original treatment, and TCM was modified on the basis of the original prescription. After 3 months of treatment, it could be seen by endoscopy that the anastomotic mild swelling and erosive lesions were significantly reduced.
Effects of behavioural swallowing therapy in patients with Parkinson’s disease: A systematic review

One study described biofeedback therapy. Athukorala et al. (2014) examined the effects of swallowing skill training with biofeedback in 10 patients with PD-related dysphagia. Skill training exercises consisted of 10 daily sessions that focussed on increased precision in muscle contraction using surface electromyography (sEMG) during swallowing using visual feedback. Each session took one hour, with 100 swallow trials partitioned into five blocks of 20 swallowing trials with dry swallow. The participants completed follow-up after two weeks of treatment, and after two weeks of a non-treatment period to evaluate skill retention. The swallow rate for liquid, sEMG durational parameters of pre-motor time, pre-swallow time, and the Quality of Life in Swallowing Disorders (SWAL-QOL) all improved immediately post-therapy. In addition, a non-treatment period showed short-term retention treatment effects.
Effectiveness of visual and acoustic biofeedback eccentric viewing training in conjunction with home exercises on visual function: a retrospective observational review

Natalia Kelly, Meri Vukicevic, Konstandina Koklanis
Whilst a significant differentiating feature of our study was the conjugate use of structured home training exercises, the biofeedback program itself was relatively consistent with previous research using microperimetry rehabilitation alone.16,18,19 Most biofeedback studies have utilized biofeedback sessions of 9–10 minutes,15,16,18,21 although we included an interval approach with breaks every 3 minutes, similar to one other study.21 Additionally, it is worth noting that within the literature there is variability in the frequency of training, the type of stimulus used and the eye trained. Some researchers have offered daily sessions, whilst others conducted 1–4 sessions per week,24,25 some have used a visual stimulus alone, whilst others have used both auditory and visual stimuli,15,23,24,38,39 and some have used monocular training of the eye with better vision, whilst others have trained both eyes.19,24,25,40 These inconsistencies could potentially contribute to the differences noted in the outcomes of our study compared to others.
Analysis of the efficacy of biofeedback for faecal incontinence after surgery for anorectal malformation

Biofeedback is currently recommended as a first-line treatment following the failure of conservative treatment methods for defaecation disorders after surgery for anorectal malformation (ARM) [1]. Many studies have been conducted on biofeedback as a treatment for faecal incontinence (FI), with an overall success rate of approximately 75%–80% [2]. Typically, paediatric patients with ARM have good surgical outcomes, but long-term follow-up indicates that approximately 8% of patients will have persistent problems with constipation, FI, and other defaecation disorders [3]. The cause of these symptoms may include anal stenosis, residual segments without nerves, enteric neuronal dysplasia, or rectal malposition [4]. At present, biofeedback is an effective choice for the treatment of defaecation disorders following surgery for ARM. Biofeedback is safer than laxatives, antidiarrheals, botulinum toxin or dextran injections, sacral nerve stimulation, and surgical options. However, the clinical efficacy of biofeedback in paediatric patients remains unknown, and there is a lack of evaluation of the techniques adopted and the outcome of biofeedback in the treatment of defaecation disorders in children. A biofeedback study was launched in our hospital in 2017, and a total of 45 paediatric patients with defaecation disorders following surgery for ARM were treated with pelvic floor biofeedback from May 2017 to December 2021. The present study analyses the therapeutic effects of biofeedback in these patients.
