ABSTRACT
This study investigated sound localization abilities in patients with bilateral conductive and/or mixed hearing loss (BCHL) when listening with either one or two middle ear implants (MEIs). Sound localization was measured by asking patients to point as quickly and accurately as possible with a head-mounted LED in the perceived sound direction. Loudspeakers, positioned around the listener within a range of +73°/-73° in the horizontal plane, were not visible to the patients. Broadband (500 Hz-20 kHz) noise bursts (150 ms), roved over a 20-dB range in 10 dB steps was presented. MEIs stimulate the ipsilateral cochlea only and therefore the localization response was not affected by crosstalk. Sound localization was better with bilateral MEIs compared with the unilateral left and unilateral right conditions. Good sound localization performance was found in the bilaterally aided hearing condition in four patients. In two patients, localization abilities equaled normal hearing performance. Interestingly, in the unaided condition, when both devices were turned off, subjects could still localize the stimuli presented at the highest sound level. Comparison with data of patients implanted bilaterally with bone-conduction devices, demonstrated that localization abilities with MEIs were superior. The measurements demonstrate that patients with BCHL, using remnant binaural cues in the unaided condition, are able to process binaural cues when listening with bilateral MEIs. We conclude that implantation with two MEIs, each stimulating only the ipsilateral cochlea, without crosstalk to the contralateral cochlea, can result in good sound localization abilities, and that this topic needs further investigation.

Hand function assessments in a clinical setting are critical for upper limb rehabilitation after spinal cord injury (SCI) but may not accurately reflect performance in an individual's home environment. When paired with computer vision models, egocentric videos from wearable cameras provide an opportunity for remote hand function assessment during real activities of daily living (ADLs). This study demonstrates the use of computer vision models to predict clinical hand function assessment scores from egocentric video. SlowFast, MViT, and MaskFeat models were trained and validated on a custom SCI dataset, which contained a variety of ADLs carried out in a simulated home environment. The dataset was annotated with clinical hand function assessment scores using an adapted scale applicable to a wide range of object interactions. An accuracy of 0.551±0.139, mean absolute error (MAE) of 0.517±0.184, and F1 score of 0.547±0.151 was achieved on the 5-class classification task. An accuracy of 0.724±0.135, MAE of 0.290±0.140, and F1 score of 0.733±0.144 was achieved on a consolidated 3-class classification task. This novel approach, for the first time, demonstrates the prediction of hand function assessment scores from egocentric video after SCI.

AIMS: To explore experiences, expectations, and involvement of children and young people (CYP) in decision-making for selective dorsal rhizotomy (SDR) surgery, post-operative physiotherapy treatment and outcomes. METHODS: A qualitative study design using one to one interviews. Five CYP (2 girls and 3 boys) participated, and interviews lasted between 45 min and 2 h. Data were analyzed using thematic analysis. RESULTS: Children and young people are reliant on their parents to make decisions and inform them of the SDR process. Experiences of living with cerebral palsy and its management are centered on their routine social, psychological, and physiological challenges. Individual characteristics and attributes of CYP have an impact on how they cope with the rehabilitation burden and adjust to their changing levels of function and participation. CONCLUSIONS: Although CYP reported that SDR offers them a greater 'freedom to choose' in how they participate in daily life, further consideration is required to meet their psychosocial needs, particularly in preparing for SDR and adjusting afterwards.

Background: Walking ability is a crucial factor for recovery and rehabilitation of spinal cord injury (SCI) patients. Objectives: The aim of this study was to investigate the effect of 12 weeks of rebound therapy on walking parameters in SCI patients. Methods: Thirty members of Isfahan Spinal Cord Injury Association participated in this experimental study using a convenience sampling method. This study was approved by the ethics committee of the University of Isfahan (IR.UI.REC.1400.118). The participants were randomly assigned to control and rebound groups using a matched randomization method. Data were collected before and after 12 weeks of rebound therapy exercise (three sessions per week) in the walking laboratory, using a seven-camera 3D motion capturing system (Qualisys motion analysis). The final data were analyzed using repeated measures ANOVA in SPSS software (significance level p < .05). Results: Rebound therapy training significantly improved all dependent variables (p < .05) except hip rotation, indicating its effectiveness for enhancing walking ability. Conclusion: Given the importance of walking function, we recommend the use of rebound therapy training as an exercise rehabilitation method for spinal cord injury patients.

Background: The proportion of patients with American Spinal Injury Association Impairment Scale (AIS) grade D traumatic spinal cord injuries (tSCI) is increasing. Although initial motor deficits can be relatively mild, some individuals fail to recover functional independence. Objectives: This study aims to identify factors associated with failure to reach complete functional independence after AIS grade D tSCI. Methods: An observational prospective cohort study was conducted at a level 1 trauma center specialized in SCI care. A prospective cohort of 121 individuals with an AIS-D tSCI was considered. The baseline characteristics, length of acute stay, need for inpatient rehabilitation, and 12-month functional status were assessed. Univariate and classification and regression tree (CART) analyses were performed to identify factors associated with reaching complete versus incomplete functional independence (defined as perfect total SCIM III score at 12-month follow-up). Results: There were 69.3%, 83.3%, and 61.4% individuals reaching complete independence in self-care, respiration/sphincter management, and mobility, respectively. A total of 64 individuals (52%) reached complete functional independence in all three domains. In the CART analysis, we found that patients are more likely to achieve complete functional independence when they have a baseline motor score ≥83 (65% individuals) and if they present fewer medical comorbidities (70% individuals if Charlson Comorbidity Index [CCI] ≤4). Conclusion: About half of individuals with AIS grade D tSCI can expect complete long-term functional independence. It is important to recognize early during acute care individuals with baseline motor score <83 or a high burden of comorbidities (CCI ≥5) to optimize their rehabilitation plan.

A drug is any substance capable of altering the functioning of a person's body and mind. In this paper, a deterministic nonlinear model was adapted to investigate the behavior of drug abuse and addiction that incorporates intervention in the form of awareness and rehabilitation. In the mathematical analysis part, the positivity and boundedness of the solution and the existence of drug equilibria have been ascertained, which shows that the model consists of two equilibria: a drug-free equilibrium and a drug endemic equilibrium point. The drug-free equilibrium was found to be both globally and locally asymptotically stable if the effective reproduction number is less than or equal to one (Rc≤1). Furthermore, we were able to show the existence of a unique drug endemic equilibrium whenever Rc>1. Global asymptotic stability of a drug endemic equilibrium point has been ascertained using a nonlinear Lyapunov function of Go-Volterra type, which reveals that the drug endemic equilibrium point is globally asymptotically stable if an effective reproduction number is greater than unity and if there is an absence of a reversion rate of mended individuals (i.e., ω=0). In addition, an optimal control problem was formulated to investigate the optimal strategy for curtailing the spread of the behavior using control variables. The control variables are massive awareness and rehabilitation intervention of both public and secret addicted individuals. The optimal control simulation shows that massive awareness control is the best to control drug addiction in a society. In sensitivity analysis section, the proportion of those who are exposed publicly shows to be a must sensitive parameter that can reduce the reproduction number, and the effective contact rate shows to be a must sensitive parameter to increase the reproduction number. Numerical simulations reveal that the awareness rate of exposed publicly and the rehabilitation rate of addicted publicly are very important parameters to control drug addiction in a society.

OBJECTIVE: Evaluate sound localization accuracy of subjects with single-sided deafness (SSD) with active transcutaneous bone conduction implants (atBCIs). STUDY DESIGN: Prospective case-control study. SETTING: Tertiary referral center. PATIENTS: Ten SSD patients (with ATBCIS) and 10 controls. INTERVENTIONS: Localization was assessed in a semianechoic chamber using a 24-speaker array. Stimuli included broadband noise (BBN) and narrowband noise (NBN). Perceived stimulus angle was recorded and compared with presented location. Statistical analyses were performed using ANOVA and Wilcoxon rank sum tests. MAIN OUTCOME MEASURES: The primary outcome measures were as follows: 1) mean angular error (MAE) error (°) and regression slope and 2) subjective benefit assessment (Speech Spatial Qualities questionnaire). RESULTS: Subjects with SSD demonstrated worse localization by MAE and regression slope compared with controls for both broadband noise (p < 0.0001) and narrowband noise at 500 Hz and 1000 kHz (p < 0.0001). There was no statistically significant difference (p = 0.1090) in slope between all groups at 4000 Hz. There was no significant difference in slope or MAE aided compared with unaided. Localization ability varied widely within the SSD cohort, with some individuals showing some ability in the unaided condition, best at 4000 Hz. Although SSQ confirmed particular difficulty in the spatial hearing domain, all domains improved with device use. CONCLUSIONS: Localization ability for individuals with SSD falls into a somewhat bimodal distribution. Some have fair localization, particularly at high frequencies, that is preserved but not improved with the atBCI. Others have minimal to no localization ability at any frequency, with no apparent device benefit.

BACKGROUND: Despite the increased risk for people with an intellectual disability developing dementia, post-diagnostic psychosocial supports such as cognitive stimulation therapy (CST) are not routinely offered and there is limited research examining this intervention with people with intellectual disabilities. The aim of this study was to explore the feasibility of CST for older adults with intellectual disability to support active ageing. METHODS: Five client participants attended a 14-session CST group and four staff attended a focus group. Reflexive thematic analysis was used to investigate the client and staff narratives. RESULTS: Three key themes were generated: (1) Brain Health, (2) Connecting with others, and (3) Barriers and Enablers. CONCLUSION: Findings indicated the suitability of CST as a way of supporting active ageing for older adults with intellectual disability. This study adds to the growing knowledge about service provision for older adults and their changing needs as they age and identifies clinical implications such as staff training to support intervention adherence.

BACKGROUND: Shared housing for adults with intellectual disabilities with staff support, is a common housing model internationally. We explored an overlooked aspect of group homes, namely the extent to which they enable a sense of 'feeling at home' for residents. METHOD: A diverse group of 19 housemates participated in a photovoice study. Participants took photos in their homes and discussed them in individual interviews and in groups. Data was analysed using reflexive thematic analysis. RESULTS: Residents' experience of home was multi-dimensional. 'Feeling at home' related to home as a site of identity cultivation (personal home); physical comfort or 'misfitting' (physical home) and home as the locus of key relationships (social home). CONCLUSION: Achieving a sense of 'feeling at home' requires engagement in practices of home-making. Many of our participants required support from staff to engage in these practices. For some housemates their experience of home was conditional and precarious.

BACKGROUND: Standing frames are commonly used by healthcare professionals in their practice with children with cerebral palsy (CP) who do not have an independent standing function. A better understanding of healthcare professionals' attitudes and experiences with standing frames may impact practice and rehabilitation. Therefore, this study aimed to investigate the standing frame practice among healthcare professionals and expand their attitude and experience with the use of standing frames for children with CP. METHODS: This is an explanatory sequential mixed methods study. A cross-sectional survey was conducted, providing quantitative data on 210 healthcare professionals' use of standing frames. The quantitative data were descriptively analysed. Subsequently, the results from the survey were followed up with five focus group interviews of healthcare professionals (n = 14). The qualitative data were analysed using thematic analysis, enabling integration between the quantitative and qualitative data. RESULTS: When quantitative and qualitative data are integrated, expansion between the two datasets occurred. The quantitative dataset emphasised the use of GMFCS levels as a guideline for recommending standing frames, whereas the qualitative data showed that the healthcare professionals' recommendations were based on individual needs. Furthermore, the healthcare professionals expanded the quantitative data, showing that the healthcare professionals' considerations regarding age and dosage were based on clinical experience, and saw the standing frame as having many benefits. CONCLUSION: The healthcare professionals had a child-centred approach, where the child's need for using a standing frame was assessed based on the functional level, stage of development, cognitive level and clinical assessment. All of these considerations showed that the use of standing frames for children with CP was individualised, thereby making it difficult to make unified descriptions.

OBJECTIVE: This study aims to assess the impact of proprioceptive training strategies with dual-task exercises on gait in people with chronic stroke. STUDY DESIGN: Systematic review. PATIENTS: Chronic stroke. METHODS: Searches were conducted in accordance with PRISMA guidelines and PICOS criteria. PubMed, Web of Science, and Scopus databases were systematically searched from November 2020 to February 2022, for eligible clinical trials. Two independent reviewers thoroughly screened potential articles for relevance and assessed the methodology quality. In accordance with the GRADE, PICOS criteria, and Cochrane risk of bias tools, the authors included articles concerning the effectiveness of dual-task in proprioceptive training on gait parameters in people with chronic stroke. RESULTS: Of 3075 identified studies, 11 articles met the inclusion criteria: 7 were randomized clinical trials, 1 was not randomized, and 3 were observational studies. The overall quality of evidence, assessed using the GRADE framework, was high, indicating a high level of confidence in the systematic review's findings. The papers involved 393 stroke patients; 241 underwent dual-task in proprioceptive training, with 152 participants in other stroke rehabilitation; within the dual-task group, 71 engaged in cognitive tasks, and 170 participated in motor tasks. dual-task in proprioceptive training improved gait speed, cadence, stride time, stride length, and step length. The best effects were observed with training 3 times a week for 4 weeks, with each session lasting 30 minutes, on speed, cadence, stride length, and step length. CONCLUSION: Current evidence suggests that proprioceptive training strategies with dual-task exercises improved walking abilities in people with chronic stroke. Specifically, it enhanced gait speed, a key indicator of clinical severity.

The durability of communication with the use of brain-computer interfaces in persons with progressive neurodegenerative disease has not been extensively examined. We report on 7 years of independent at-home use of an implanted brain-computer interface for communication by a person with advanced amyotrophic lateral sclerosis (ALS), the inception of which was reported in 2016. The frequency of at-home use increased over time to compensate for gradual loss of control of an eye-gaze-tracking device, followed by a progressive decrease in use starting 6 years after implantation. At-home use ended when control of the brain-computer interface became unreliable. No signs of technical malfunction were found. Instead, the amplitude of neural signals declined, and computed tomographic imaging revealed progressive atrophy, which suggested that ALS-related neurodegeneration ultimately rendered the brain-computer interface ineffective after years of successful use, although alternative explanations are plausible.

During the last decade, there has been a move towards consumer-centric hearing healthcare. This is a direct result of technological advancements (e.g., merger of consumer grade hearing aids with consumer grade earphones creating a wide range of hearing devices) as well as policy changes (e.g., the U.S. Food and Drug Administration creating a new over-the-counter [OTC] hearing aid category). In addition to various direct-to-consumer (DTC) hearing devices available on the market, there are also several validated tools for the self-assessment of auditory function and the detection of ear disease, as well as tools for education about hearing loss, hearing devices, and communication strategies. Further, all can be made easily available to a wide range of people. This perspective provides a framework and identifies tools to improve and maintain optimal auditory wellness across the adult life course. A broadly available and accessible set of tools that can be made available on a digital platform to aid adults in the assessment and as needed, the improvement, of auditory wellness is discussed.

BACKGROUND: Experimental studies have shown that repetitive trans-spinal magnetic stimulation (TsMS) decreases demyelination and enables recovery after spinal cord injury (SCI). However, the usefulness of TsMS in humans with SCI remains unclear. Therefore, the main objective of this study is to evaluate the effects of TsMS combined with kinesiotherapy on SCI symptoms. We describe a protocol treatment with TsMS and kinesiotherapy in a patient with SCI due to neuromyelitis optica (NMO)-associated transverse myelitis. CASE PRESENTATION: A 23-year-old white male with NMO spectrum disorders started symptoms in 2014 and included lumbar pain evolving into a mild loss of strength and sensitivity in both lower limbs. Five months later, the symptoms improved spontaneously, and there were no sensorimotor deficits. Two years later, in 2016, the symptoms recurred with a total loss of strength and sensitivity in both lower limbs. Initially, physiotherapy was provided in 15 sessions with goals of motor-sensory recovery and improving balance and functional mobility. Subsequently, TsMS (10 Hz, 600 pulses, 20-seconds inter-trains interval, at 90% of resting motor threshold of the paravertebral muscle) was applied at the 10th thoracic vertebral spinous process before physiotherapy in 12 sessions. Outcomes were assessed at three time points: prior to physiotherapy alone (T-1), before the first session of TsMS combined with kinesiotherapy (T0), and after 12 sessions of TsMS combined with kinesiotherapy (T1). The patient showed a 25% improvement in walking independence, a 125% improvement in balance, and an 18.8% improvement in functional mobility. The Patient Global Impression of Change Scale assessed the patient's global impression of change as 'much improved'. CONCLUSION: TsMS combined with kinesiotherapy may safely and effectively improve balance, walking independence, and functional mobility of patients with SCI due to NMO-associated transverse myelitis.

The control strategy of rehabilitation robots should not only adapt to patients with different levels of motor function but also encourage patients to participate voluntarily in rehabilitation training. However, existing control strategies usually consider only one of these aspects. This study proposes a voluntary and adaptive control strategy that solves both questions. Firstly, the controller switched to the corresponding working modes (including challenge, free, assistant, and robot-dominant modes) based on the trajectory tracking error of human-robot cooperative movement. To encourage patient participation, a musculoskeletal model was used to estimate the patient's active torque. The robot's output torque was designed as the product of the active torque and a coefficient, with the coefficient adaptively changing according to the working mode. Experiments were conducted on two healthy subjects and four hemiplegic patients using an ankle rehabilitation robot. The results showed that this controller not only provided adaptive the robot's output torque based on the movement performance of patients but also encouraged patients to complete movement tasks themselves. Therefore, the control strategy has high application value in the field of rehabilitation.

BACKGROUND: The effectiveness of telemedicine in aiding rehabilitation exercises among patients with rotator cuff (RC) disorders remains unknown. Therefore, this meta-analysis aimed to assess the effectiveness of telemedicine in patients with RC disorders. METHODS: Randomized clinical trials (RCTs) on the effectiveness of telemedicine in patients with RC disorders were summarized through a meta-analysis. A systematic search for these RCTs was conducted in PubMed, Cochrane, Embase, and Web of Science databases up to July 2024. Statistical analysis was performed using Stata 16. Publication bias was estimated with the funnel plot and Egger's test. RESULTS: Ten studies involving 497 participants (telemedicine group = 248 and conventional group = 249) were enrolled, with follow-up durations ranging from 8 weeks to 48 weeks. Functional outcomes measured by the Constant-Murley score were markedly improved after treatment in the telemedicine group compared to the conventional group. Moreover, compared to conventional treatment, telemedicine significantly improved shoulder function evaluated by Quick Disabilities of the Arm, Shoulder, and Hand Score, relieved pain assessed by visual analog scale pain score, and improved range of motion after treatment and in the final follow-up period. CONCLUSION: Telemedicine has demonstrated potential in alleviating pain and enhancing shoulder function and motion in patients with RC injuries. It may be a feasible intervention for rehabilitation exercises. Further research with a large sample size and standardized treatment is warranted to validate these findings.

BACKGROUND: Restorative treatment options for edentulous patients range from traditional dentures to fixed restorations. The proper selection of materials greatly influences the longevity and stability of fixed restorations. Most prosthetic parts are frequently fabricated from titanium. Ceramics (e.g. zirconia) and polymers (e.g. PEEK and BIOHPP) have recently been included in these fabrications. The mandibular movement produces complex patterns of stress and strain. Mandibular fractures may result from these stresses and strains exceeding the critical limits because of the impact force from falls or accidents. Therefore, it is necessary to evaluate the biomechanical behavior of the edentulous mandible with different restorations under different loading situations. OBJECTIVE: This study analyzes the biomechanical behavior of mandibles after four prosthetic restorations for rehabilitation under normal and impact loading scenarios. MATERIAL AND METHODS: The mandibular model was constructed with a fixed restoration, which was simulated using various materials (e.g. Titanium, Zirconia & BIOHPP), under frontal bite force, maximum intercuspation, and chin impact force. From the extraction of tensile and compressive stresses and strains, as well as the total deformation of mandible segments, the biomechanical behavior and clinical situations were studied. RESULTS: Under frontal bite, the anterior body exhibited the highest tensile (60.34 MPa) and compressive (108.81 MPa) stresses using restoration 4, while the condyles and angles had the lowest tensile (7.12 MPa) and compressive (12.67 MPa) stresses using restoration 3. Under maximum intercuspation, the highest tensile (40.02 MPa) and compressive (98.87 MPa) stresses were generated on the anterior body of the cortical bone using restoration 4. Additionally, the lowest tensile (7.7 MPa) and compressive (10.08 MPa) stresses were generated on the condyles and angles, respectively, using restoration 3. Under chin impact, the highest tensile (374.57 MPa) and compressive (387.3 MPa) stresses were generated on the anterior body using restoration 4. Additionally, the lowest tensile (0.65 MPa) and compressive (0.57 MPa) stresses were generated on the coronoid processes using restoration 3. For all loading scenarios, the anterior body of the mandible had the highest stress and strain values compared with the other segments. Compared to the traditional titanium restoration.2, restoration.1(zirconia) increases the tensile and compressive stresses and strains on the mandibular segments, in contrast to restoration.3 (BIOHPP). In addition, zirconia implants exhibited higher displacements than the other implants. CONCLUSION: In the normal loading scenario, the tensile and compressive stresses and strains on the mandible were within the allowable limits when all restorations were used. Under the chin impact loading scenario, the anterior body of the mandible was damaged by restorations 1 and 4.

BACKGROUND: Rotator cuff tears are a common shoulder injury that significantly impacts patients' daily lives and work abilities. Although surgical treatment methods for rotator cuff tears have been continuously improved with advances in medical technology, postoperative rehabilitation remains challenging. Therefore, finding effective rehabilitation treatments is crucial for improving patient prognosis and enhancing quality of life. This study will aim to systematically evaluate the impact of low-intensity pulsed ultrasound (LIPUS) on postoperative rehabilitation of rotator cuff tears, comprehensively assessing the efficacy and safety of LIPUS in postoperative recovery. METHODS: This protocol will search multiple databases including PubMed/MEDLINE, Embase, Cochrane Library, CNKI, Scopus, and Web of Science to identify randomized controlled trials related to LIPUS for postoperative rehabilitation of rotator cuff tears. The search will encompass literature published from the inception of the databases up to April 2024. Methodological quality assessment and data extraction will be conducted using the Cochrane Handbook for Systematic Reviews of Interventions and PRISMA guidelines. Meta-analysis will be performed on appropriate studies using either random-effects or fixed-effects models, and subgroup analyses will be conducted to explore potential heterogeneity. Studies meeting the inclusion criteria will be included in the analysis. All analyses will be performed using Stata version 16.0. RESULTS: The incidence of rotator cuff tear rates will be assessed by imaging techniques such as MRI or ultrasound. Pain intensity will be scored using standardized pain assessment scales, such as the Visual Analog Scale (VAS). Improved range of motion (ROM) in shoulder flexion, abduction, and rotation. Functional outcomes will be evaluated using effective measures such as Constant-Murley scores (CMS) and shoulder joint scores by American Shoulder and Elbow Surgeons (ASES). Adverse events associated with LIPUS therapy, including skin irritation, increased pain, or any other complications. Subgroup analysis will also be carried out if possible. DISCUSSION AND CONCLUSION: Following the meta-analysis, we will assess the overall effect of LIPUS on postoperative rehabilitation of rotator cuff tears, and further explore its impact on aspects such as pain relief, functional improvement, and postoperative complications. It is anticipated that this study will provide comprehensive evidence regarding the role of LIPUS in postoperative rehabilitation of rotator cuff tears, guiding clinical practice and future research. The resultant manuscript will be submitted for publication in a peer-reviewed journal. PROTOCOL REGISTRATION NUMBER: CRD42024530798.

In order to treat and research the development, progression, therapy and prevention of cardiological and psychosomatic disorders and their interactions, the field of psychocardiology has been established in recent years and now offers several treatment options.The well-known somatic risk factors for cardiovascular diseases such as smoking, diabetes mellitus, arterial hypertension and acquired or congenital lipid metabolism disorders, lack of exercise, malnutrition and sleep-related disorders are often related to psychosocial risk factors. Conversely, mental illnesses such as depression and post-traumatic stress disorder can also be viewed as independent risk factors for cardiovascular diseases.Somatic illnesses can, in turn, result in significant psychological reactions that have a severely negative impact on the course of the disease, participation and quality of life.In addition to the scientific research into these connections, psychocardiology offers a clinical specialty that questions, diagnoses and provides treatment for psychosocial connections in cardiovascular patients.The aim of this article is primarily to convey clinical and practical aspects of psychocardiology and the most important psychological comorbidities in connection with heart disease. In addition, it should be shown which therapeutic offers are available in the medical care structures and how therapy can be carried out. Psychotherapy and exercise therapy are preferred for the treatment of these comorbid disorders. The possibility of psychopharmacological therapy for cardiovascular patients is also presented, especially because of possible problematic medication interactions.
