ABSTRACT
To investigate the effects of health education combined with biofeedback electrical stimulation on maternal postpartum pelvic floor function and psychology. The clinical data of 80 patients with postpartum pelvic floor dysfunction (PFD) from May 2020 to May 2022 were selected as retrospective study subjects, and 40 cases were divided into the comparison group and the observation group according to the different intervention methods. Among them, the comparison group implemented biofeedback electrical stimulation and guidance, and the observation group implemented Greene health education and Kegel pelvic floor rehabilitation training intervention based on the comparison group. The differences in pelvic floor muscle strength, sexual quality of life, anxiety, and depression in the 2 groups with postpartum PFD were compared. Comparison of pelvic floor muscle strength: before the intervention (Pâ >â .05) and after the intervention, the anterior resting mean electromyography (EMG), slow muscle mean EMG, fast muscle maximum EMG, and mixed muscle mean EMG values of patients in the observation group were higher than those in the comparison group, and the posterior resting mean EMG values were lower than those in the comparison group (Pâ <â .05). There was no statistically significant difference in the Hospital Anxiety and Depression Scale (HADS) scores and anxiety and depression subscale scores between the 2 groups of patients before intervention (Pâ >â .05). After the intervention, the HADS scores and anxiety and depression subscale scores were lower than those before the intervention in both groups, and the differences were statistically significant in the intervention group than in the comparison group (Pâ <â .05). There was no statistically significant difference between The Chinese Female Sexual Life Quality Questionnaire scores of both groups before the intervention (Pâ >â .05). Sexual desire, vaginal lubrication, sexual arousal, sexual satisfaction, orgasm, and painful intercourse improved in both groups after the intervention, and the scores in the intervention group were higher than those in the comparison group (Pâ <â .05). Health education combined with biofeedback electrical stimulation can effectively improve the quality of patients' sexual life, improve the pelvic floor muscle strength of patients with postpartum PFD, enhance patients' confidence, reduce patients' anxiety and depression, and effectively improve patients' psychological status.

PURPOSE: Propose and verify the efficiency of myofunctional intervention program to attenuate facial aging signs and balance the orofacial functions. METHODS: Thirty women, aged 50 to 60 years, randomly divided into: therapy group (TG) submitted to Orofacial Myofunctional Therapy and electromyographic biofeedback group (EBG), submitted to the same program associated with electromyographic biofeedback for chewing, swallowing, and smiling functions training. Aesthetic and oromyofunctional aspects were assessed from photographs, videos, MBGR Protocol and scales for assessing facial aging signs, described in the literature. 50-minute sessions were held weekly for nine weeks and monthly for six months after washout period. Three assessments, identical to the initial one, were performed in the tenth week, eighth week after washout and conclusion of the research. The participants responded to the Satisfaction Questionnaire on the tenth week. RESULTS: The statistical analysis using the ANOVA, Tukey and Mann Whitney tests, for inter and intragroup comparison, showed that: intervention promoted attenuation of facial aging signs mainly in TG group, balance of chewing and swallowing functions in both groups; there was an impact of electromyographic biofeedback on the degree of participants' satisfaction, greater for EBG; interruption of the program for eight weeks resulted in aesthetic losses, mainly in TG, yet not functional losses, in both groups; the six monthly sessions had a limited impact on overcoming the esthetic losses that occurred after washout. CONCLUSION: The proposed program resulted in attenuation of aging signs, mainly in the TG group and improvement in orofacial functions, in both groups.

Post-stroke patients often experience psychological distress and autonomic nervous system (ANS) dysregulation, impacting their well-being. This study evaluated the effectiveness of heart rate variability (HRV) biofeedback on cognitive, motor, psychological, and ANS functions in sixty-two ischemic stroke patients (43 males, mean age = 60.1) at a Medical Center in southern Taiwan. To prevent interaction, we allocated patients to the HRV biofeedback or control (usual care) group based on their assigned rehabilitation days, with 31 patients in each group. Assessments conducted at baseline, three, and six months included the Montreal Cognitive Assessment (MoCA), Fugl-Meyer Assessment for Upper Extremities (FMA-UE), Perceived Stress Scale, Hospital Anxiety and Depression Scales (HADS), and HRV indices. Mixed-effect models were used to analyze Group by Time interactions. The results revealed significant interactions across all functions. At 3 months, significant improvements in the HRV biofeedback group were observed only in MoCA, FMA-UE, and HADS-depression scores compared to the control group. By 6 months, all measured outcomes demonstrated significant improvements in the biofeedback group relative to the control group. These results suggest that HRV biofeedback may be an effective complementary intervention in post-stroke rehabilitation, warranting further validation.

BACKGROUND: Patients with neurological disorders including stroke use rehabilitation to improve cognitive abilities, to regain motor function and to reduce the risk of further complications. Robotics-assisted tilt table technology has been developed to provide early mobilisation and to automate therapy involving the lower limbs. The aim of this study was to evaluate the feasibility of employing a feedback control system for heart rate (HR) during robotics-assisted tilt table exercise in patients after a stroke. METHODS: This feasibility study was designed as a case series with 12 patients ( n = 12 ) with no restriction on the time post-stroke or on the degree of post-stroke impairment severity. A robotics-assisted tilt table was augmented with force sensors, a work rate estimation algorithm, and a biofeedback screen that facilitated volitional control of a target work rate. Dynamic models of HR response to changes in target work rate were estimated in system identification tests; nominal models were used to calculate the parameters of feedback controllers designed to give a specified closed-loop bandwidth; and the accuracy of HR control was assessed quantitatively in feedback control tests. RESULTS: Feedback control tests were successfully conducted in all 12 patients. Dynamic models of heart rate response to imposed work rate were estimated with a mean root-mean-square (RMS) model error of 2.16 beats per minute (bpm), while highly accurate feedback control of heart rate was achieved with a mean RMS tracking error (RMSE) of 2.00 bpm. Control accuracy, i.e. RMSE, was found to be strongly correlated with the magnitude of heart rate variability (HRV): patients with a low magnitude of HRV had low RMSE, i.e. more accurate HR control performance, and vice versa. CONCLUSIONS: Feedback control of heart rate during robotics-assisted tilt table exercise was found to be feasible. Future work should investigate robustness aspects of the feedback control system. Modifications to the exercise modality, or alternative modalities, should be explored that allow higher levels of work rate and heart rate intensity to be achieved.

OBJECTIVE: To explore the effects of electric stimulation and biofeedback therapy in patients with postpartum pelvic organ prolapse and to identify factors that can affect therapeutic efficacy outcomes. METHOD: This retrospective study analysed clinical data about patients with postpartum pelvic organ prolapse. A total of 328 women with pelvic organ prolapse at 6 weeks postpartum were recruited from one tertiary hospitals in Sichuan province in China, between March 2019 and March 2022. The prognostic factors of therapeutic efficacy were analysed using logistic regression and decision tree model. RESULTS: Overall, 259 women showed clinical benefits from the treatment. The logistic regression model showed that parity, pelvic floor muscle training at home, and the pelvic organ prolapse quantitation stage before treatment were independent prognostic factors. The decision tree model showed that the pelvic organ prolapse quantitation stage before treatment was the main prognostic factor, followed by parity. There was no significant difference in the area under the receiver operating characteristic curve between the two models. CONCLUSION: Parity, pelvic floor muscle training at home, and the pelvic organ prolapse quantitation stage before treatment were important prognostic factors of electric stimulation and biofeedback therapy on postpartum pelvic organ prolapse.

INTRODUCTION: Wearable neuromuscular and biomechanical biofeedback technology has the potential to improve patient outcomes by facilitating exercise interventions. We will conduct a systematic review to examine whether the addition of wearable biofeedback to exercise interventions improves pain, disability and quality of life beyond exercise alone for adults with chronic non-specific spinal pain. Specific effects on clinical, physiological, psychological, exercise adherence and safety outcomes will also be examined. METHODS AND ANALYSIS: A systematic search will be conducted from inception to February 2024. Full articles in the English language will be included. MEDLINE, PubMed, CINAHL, EMBASE, Web of Science, PsycINFO, AMED, SPORTDiscus, CENTRAL databases, clinical trial registries and ProQuest (PQDT) will be used to search for eligible studies. Grey literature and conference proceedings (2022-2024) will be searched for relevant reports. Randomised controlled trials using wearable neuromuscular or kinematic biofeedback devices as an adjunct to exercise interventions for the treatment of chronic spinal pain will be included in this systematic review. The comparators will be wearable biofeedback with exercise versus exercise alone, or wearable biofeedback with exercise versus placebo and exercise. Risk of bias will be assessed using Cochrane Back Review Group criteria and the quality of evidence using Grading of Recommendations Assessment, Development and Evaluation recommendations. ETHICS AND DISSEMINATION: The systematic review will be based on published studies, and therefore, does not require ethical approval. The study results will be submitted for publication in an international, open-access, peer-reviewed journal and shared through conferences and public engagement. PROSPERO REGISTRATION NUMBER: CRD42023481393.

Lower back disorders (LBDs) affect a large proportion of the population, and treatment for LBDs have been shifting toward individualized, patient-centered approaches. LBDs are typically associated with poor proprioception. Therefore, there has been a recent uptake in the utilization of wearable sensors that can administer biofeedback in various industrial, clinical, and performance-based settings to improve lumbar proprioception. The aim of this study was to investigate whether wearable sensor-derived acute auditory biofeedback can be used to improve measures of gross lumbar proprioception. To assess this, healthy participants completed an active target repositioning protocol, followed by a training period where lumbar-spine posture referenced auditory feedback was provided for select targets. Target re-matching abilities were captured before and after acute auditory biofeedback training to extract measures related to accuracy and precision across spine flexion targets (i.e., 20%, 40%, 60%, 80% maximum). Results suggest a heterogenous response to proprioceptive training whereby certain individuals and spine flexion targets experienced positive effects (i.e., improved accuracy and precision). Specifically, results suggest that mid-range flexion targets (i.e., 40-60% maximum flexion) benefited most from the acute auditory feedback training. Further, individuals with poorer repositioning abilities in the pre-training assessment showed the greatest improvements from the auditory feedback training.

OBJECTIVE: This study was conducted to investigate the effect of biofeedback (BF) on the rehabilitation of children with nonneurological dysfunctional voiding (NDV). METHODS: RCTs were retrieved from various databases (published from inception to February 29, 2024). The effects of the BF and non-BF treatments were compared. A random-effects model was used to evaluate the combined data. RESULTS: Meta-analysis revealed that BF increased the maximum urinary flow rate (SMD = 3.78, 95% CI 1.33â¼6.22), improved urination time (SMD = 5.88, 95% CI 3.75â¼8.01), and reduced the postvoid residual (SMD = -19.18, 95% CI -27.03â¼-11.33) and urinary tract infection incidence (RR = 0.43, 95% CI 0.21â¼0.87). Electromyogram activity (RR = 0.46, 95% CI 0.25â¼0.84) and abnormal urination patterns (RR = 0.51, 95% CI 0.35â¼0.74) improved, with effects persisting for more than 1 year. However, the effect of BF on the mean urinary flow rate in children with NDV was significant only after 1 year of follow-up (SMD = 1.90, 95% CI 0.87â¼2.92). CONCLUSION: Existing evidence indicates that BF can enhance urinary parameters and patterns in children with NDV. However, its effectiveness in addressing constipation, daytime urinary incontinence, and nocturnal urinary incontinence is not substantial. High-quality randomized controlled trials can offer additional insights.

INTRODUCTION: Expanding the use of surface electromyography-biofeedback (EMG-BF) devices in different therapeutic settings highlights the gradually evolving role of visualizing muscle activity in the rehabilitation process. This review evaluates their concepts, uses, and trends, combining evidence-based research. AREAS COVERED: This review dissects the anatomy of EMG-BF systems, emphasizing their transformative integration with machine-learning (ML) and deep-learning (DL) paradigms. Advances such as the application of sophisticated DL architectures for high-density EMG data interpretation, optimization techniques for heightened DL model performance, and the fusion of EMG with electroencephalogram (EEG) signals have been spotlighted for enhancing biomechanical analyses in rehabilitation. The literature survey also categorizes EMG-BF devices based on functionality and clinical usage, supported by insights from commercial sectors. EXPERT OPINION: The current landscape of EMG-BF is rapidly evolving, chiefly propelled by innovations in artificial intelligence (AI). The incorporation of ML and DL into EMG-BF systems augments their accuracy, reliability, and scope, marking a leap in patient care. Despite challenges in model interpretability and signal noise, ongoing research promises to address these complexities, refining biofeedback modalities. The integration of AI not only predicts patient-specific recovery timelines but also tailors therapeutic interventions, heralding a new era of personalized medicine in rehabilitation and emotional detection.

BACKGROUND: Low anterior resection syndrome (LARS) is a distressing condition that affects approximately 25-80% of patients following surgery for rectal cancer. LARS is characterized by debilitating bowel dysfunction symptoms, including fecal incontinence, urgent bowel movements, and increased frequency of bowel movements. Although biofeedback therapy has demonstrated effectiveness in improving postoperative rectal control, the research results have not fulfilled expectations. Recent research has highlighted that stimulating the pudendal perineal nerves has a superior impact on enhancing pelvic floor muscle function than biofeedback alone. Hence, this study aims to evaluate the efficacy of a combined approach integrating biofeedback with percutaneous electrical pudendal nerve stimulation (B-PEPNS) in patients with LARS through a randomized controlled trial (RCT). METHODS AND ANALYSIS: In this two-armed multicenter RCT, 242 participants with LARS after rectal surgery will be randomly assigned to undergo B-PEPNS (intervention group) or biofeedback (control group). Over 4 weeks, each participant will undergo 20 treatment sessions. The primary outcome will be the LARS score. The secondary outcomes will be anorectal manometry and pelvic floor muscle electromyography findings and the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire-Colorectal 29 (EORTC QLQ-CR29) scores. Data will be collected at baseline, post-intervention (1 month), and follow-up (6 months). DISCUSSION: We anticipate that this study will contribute further evidence regarding the efficacy of B-PEPNS in alleviating LARS symptoms and enhancing the quality of life for patients following rectal cancer surgery.

Ego-depletion describes a state of mind, where the capacity for self-control is temporarily depleted after a primary self-control action. The aim of this study was to investigate whether a brief virtual reality-based mindfulness breathing meditation with integrated biofeedback can be considered an effective strategy to counteract the detrimental effects of ego depletion on motor skill performance under pressure. The study included two experiments, each of them designed as counterbalanced cross-over trials and based on an a priori sample-size calculation. Within each experiment, participants completed two appointments in a randomly assigned order, during which they were asked to perform 20 basketball free throws (N = 18; Experiment 1) or 20 penalty kicks at a football goal in four target squares (N = 16; Experiment 2) under pressure pre and post the following conditions: Stroop-test-induced ego depletion followed by a 15 min resting break, Stroop-test-induced ego depletion followed by a 15 min virtual reality-based mindfulness breathing meditation with integrated biofeedback. Results indicate that, in comparison to a resting break, a brief virtual reality-based mindfulness meditation with integrated biofeedback can counteract the detrimental effects of ego-depletion (Experiment 2) and enhance motor skill performance under pressure (Experiment 1, 2) Implications for researchers and practitioners are derived in light of the identified methodological limitations.

OBJECTIVES: To analyze the management strategies in the children who had treatment-resistant dysfunctional voiding (DV). METHODS: Among 75 children with DV who underwent pelvic floor biofeedback therapy (BF) between 2013 and 2020, 16 patients (14 girls, 87.5%) with a mean age of 9.81 ± 2.53 years that showed incomplete clinical response following urotherapy and initial BF sessions were retrospectively reviewed. The demographic and clinical characteristics, DVSS, and uroflowmetry parameters were recorded before and after the initial BF sessions. Subsequent treatments after initial BF and clinical responses of patients were noted. RESULTS: Clinical success was observed in one patient by addition of an anticholinergic and in three patients with combination of salvage BF sessions and anticholinergics, whom had predominant overactive bladder (OAB) symptoms. The success rate of TENS alone and in combination with other treatment modalities was 88.8% (8/9 patients). In addition, salvage BF sessions (range 2 to 3) enabled clinical success in five (50%) of 10 cases as a combination with anticholinergics or TENS. In case of incomplete emptying without OAB, adequate clinical response to Botulinum-A was observed during an average follow-up of 29 months in two boys who did not respond to alpha-blockers, even though one required repeat injection after 10 months. The total clinical success rate was 87.5% (14/16 patients) after a median follow-up of 24 months. VV-EBC and Qmax increased by a mean of 30.89% and 7.13 mL/min, respectively, whereas DVSS decreased by a mean of 8.88 points and PVR-EBC decreased by a median of 19.04%. CONCLUSIONS: Our findings showed that clinical success in resistant DV was achieved by various combination treatments in the majority of children. However, a small group may still have persistent, bothersome symptoms despite multiple treatment modalities.

BACKGROUND: Although biofeedback with contingent electrical stimulation (CES) has demonstrated the reduction effect on sleep bruxism (SB), the relationship between the actual applied CES intensity and efficacy remains uncertain. OBJECTIVE: This study aimed to investigate whether the reduction of bruxism events and jaw muscle symptoms could vary according to the intensity of CES and in probable sleep bruxers. METHODS: Twenty probable sleep bruxers were initially screened for bruxer confirmation based on a 2-week recording of SB events with a portable electromyography recorder (BUTLER®GrindCare®, GC4). A 3-week recording was conducted without CES using a GC4, followed by another 3-week recording with CES. At baseline and before and after the CES (+) session, clinical muscle symptoms were assessed using a 0-10 numerical rating scale (NRS). The relationships between the actual applied CES intensity and the number of SB events/hour, as well as the NRS of clinical muscle symptoms, were analysed. RESULTS: The actual applied CES intensity was positively correlated with the reduction rate of the number of SB events/hour (R = .643, p = .002), as well as with the reduction rate of NRS for pain, unpleasantness, fatigue, tension and stiffness (R > .500, p < .011). CONCLUSION: Higher CES elicited a more robust reduction in SB events and clinical muscle symptoms, in probable bruxers. Prior to selecting CES biofeedback as a management option for SB, it would be beneficial to assess the tolerance threshold of CES in each bruxer in order to predict the effectiveness of CES in probable sleep bruxers.

PURPOSE: This study investigates the learning efficacy for partial weight load before discharge as well as the impact of biofeedback during the learning process. METHODS: We monitored weight-bearing in 57 patients who had surgery for ankle fractures. Continuous measurements without and with biofeedback were performed in the early postoperative stage in order to, first, assess how well these patients could apply what they have learned before being discharged, and second, to examine the influence of biofeedback. RESULTS: Using conventional teaching methods, only about one-third of patients (36.8% on the ground and 29.2% on the stairs) were able to maintain a satisfactory load. One-fourth of the patients did not place any weight on their leg, which was shown to be due to excessive pain at the time of the measurement (p < 0.05). A further one-fourth loaded inadequately low, while the remainder loaded excessively. Patients benefited significantly from the activation of audio-visual biofeedback in real time. As a result, loads in a target zone between 15 and 30 kg could be significantly increased (p < 0.05). CONCLUSION: We conclude that the majority of ankle fracture patients were unable to learn partial weight bearing in the early postoperative stage using traditional techniques. Additionally, each patient's ability to carry out a given loading varied. Using an audio-visual real-time biofeedback modality led to significantly improved performance. These findings support the proposed utility of audiovisual feedback in early rehabilitation. With the use of outpatient real-time biofeedback systems, therapists will be able to respond specifically to the needs of each individual patient.

Self-compassion training has been shown to deliver mental health benefits and preliminary evidence suggests it might also be possible to deliver these benefits effectively via virtual reality (VR) technology. However, which features of the VR training environment influence these training benefits remains poorly understood. This study was designed to provide the first empirical test of the potential value of visual biofeedback during self-compassion training. It was theorised that the provision of biofeedback may increase the benefits of training by increasing mindfulness, a core component of self-compassion. Sixty participants were randomly allocated to one of two experimental conditions, both of which comprised VR-based self-compassion training, but only one of which included visual biofeedback (a red pulsating light representing heart rate). Relative to scores at baseline, participants reported greater self-compassion, and lower self-criticism, anxiety, and stress after VR self-compassion training. However, the provision of biofeedback did not influence the strength of these training effects. These data provide further evidence that VR administered self-compassion training may deliver potentially important mental health benefits, but also meaningfully extends this literature by proving the first evidence that visual biofeedback does not influence the strength of these benefits.

OBJECTIVES: Investigate effects of integrated training for pelvic floor muscles (PFM) with and without transabdominal ultrasonography (TAUS) imaging-guided biofeedback in postpartum women with pregnancy-related pelvic girdle pain (PPGP). DESIGN: Three-arm, single-blinded randomized controlled trial SETTING: University laboratory PARTICIPANTS: Fifty-three postpartum women with PPGP randomized into stabilization exercise with TAUS-guided biofeedback (BIO+EXE), exercise (EXE), and control (CON) groups. INTERVENTIONS: The BIO+EXE and EXE groups underwent an 8-week exercise program, with the BIO+EXE group receiving additional TAUS-guided biofeedback for PFM training during the first 4 weeks. The CON group only received a pelvic educational session. MAIN OUTCOME MEASURES: Primary outcomes included self-reported pain (numeric rating scale) and disability (pelvic girdle questionnaire). Secondary outcomes included functional tests (active straight leg raising [ASLR] fatigue, timed up-and-go, and 6-meter walking tests) and muscle contractibility indicated by muscle thickness changes for abdominal muscles and bladder base displacement for PFM (ultrasonographic measures). RESULTS: The BIO+EXE group had lower pain [1.8 (1.5) vs. 4.4 (1.5), mean difference -2.6, 95% confidence interval (CI) -3.9 to -1.2] and disability [14% (10) vs. 28% (21), mean difference -14, 95% CI -25 to -2] and faster walking speed [3.1 seconds (1) vs. 3.3 seconds (1), mean difference -0.2, 95% CI -1.0 to -0.2] than the CON group. The EXE group only had lower pain intensity compared to the CON group [2.7 (2.0) vs. 4.4 (1.5), mean difference -1.7, 95% CI -3.1 to -0.4]. No significant differences were observed among groups in timed up-and-go, ASLR fatigue, or muscle contractibility. CONCLUSIONS: Integrated training for PFM and stabilization with TAUS-guided biofeedback seems to be beneficial for reducing pain and disability in postpartum women with PPGP.
