Objective: To identify early clinical predictors associated with dysphagia and delayed swallowing recovery in patients with traumatic brain injury (TBI). Methods: In this retrospective study, we enrolled adult TBI patients admitted to the rehabilitation unit of a tertiary medical center between June 2019 and June 2023. Data on baseline characteristics, neurological status, imaging findings, and rehabilitation-related variables were collected. Swallowing function was assessed using two indicators: (1) nasogastric (NG) tube retention and (2) the Functional Oral Intake Scale (FOIS) scores at 1, 4, and 12 weeks post-injury. Regression analyses were conducted to identify predictors associated with dysphagia and swallowing recovery. Results: A total of 160 patients were included. At 1 week post-injury, longer intensive care unit (ICU) stay, poor initial sitting balance and use of sedative medication in ICU were associated with NG tube retention. At 4 weeks, lower initial Rancho Los Amigos Scale (RLAS) scores, immobility-related complications, longer hospitalization, and temporal lobe hematomas were associated with persistent NG tube dependence. By 12 weeks, older age, delayed ability to follow commands, and poor initial sitting balance remained associated with NG tube retention. FOIS outcomes were also associated with older age, delayed time to follow commands, impaired initial sitting balance, prolonged ICU stay, temporal lobe hematomas, lower initial RLAS scores, immobility-related complications, prolonged endotracheal tube placement and extended hospital stays. Conclusion Impaired cognitive status, poor physical function, immobility-related complications, and temporal lobe hematomas were key factors associated with dysphagia and delayed oral intake in individuals with TBI.

Objective: To compare the outcome of rectal and surface electrode stimulation, when performed concomitantly with routine anal sphincter (AS) exercises and bio-feedback training, in children who have received corrective surgery to address Hirschsprung disease (HD). Methods: Sixty-seven patients (pediatric) who underwent corrective surgery due to HD were randomly assigned to Group A (rectal electrode, n=34) or Group B (surface electrode, n=33). The two groups were given the same protocols of AS and bio-feedback training. The Pediatric Quality of Life Inventory (PedsQL), Bowel Function Score (BFS), Pediatric Incontinence and Constipation Scoring System Scale (PICSS) were measured at baseline, post intervention and follow-up. Results: There were significant improvements in both groups over time across all outcomes. PedsQL increased (d=0.42–1.28, η²p up to 0.37), BFS improved notably (d=1.21, η²p=0.35), and PICSS decreased (d up to 1.15, η²p=0.33). The greatest gains occurred from baseline to follow-up, with smaller but significant changes from post-treatment to follow-up, indicating sustained effects. Conclusion Electrical stimulation with rectal electrodes, combined with AS exercises and bio-feedback training, is a major way of improving bowel functioning, continence and quality of life in Hirschsprung child. Such results highlight the promise of multimodal rehabilitation and should be supported by additional multicenter studies.

Objective: To synthesize the available evidence on the effects of constraint-induced movement therapy (CIMT) in children with hemiplegic cerebral palsy (CP), focusing on upper limb functional outcomes and neuroplasticity-related changes assessed through direct or indirect measures. Methods: This scoping review was conducted in accordance with PRISMA-ScR guidelines and was prospectively registered on the Open Science Framework (DOI: 10.17605/OSF.IO/DU8RE). A search of four databases (PubMed, Scopus, Embase, and Web of Science) was performed to identify studies involving children (0–18 years) with CP who received CIMT as the primary intervention. Eligible studies assessed neuroplasticity through neuroimaging or neurophysiological techniques. Results: Eleven studies involving 221 children met the inclusion criteria. CIMT protocols varied in duration, intensity, and setting (e.g., clinical, home-based, camp-based). Across studies, CIMT was associated with improvements in upper limb function and spontaneous use. Neuroplastic changes included increased activation in the contralateral sensorimotor cortex, normalization of somatosensory responses, and structural brain adaptations. Adjunctive therapies such as repetitive transcranial magnetic stimulation, transcutaneous auricular vagus nerve stimulation, or occupational therapy further enhanced outcomes. Conclusion CIMT is an effective intervention that promotes cortical reorganization and improves motor function in children with hemiplegic CP. Customizing rehabilitation based on neurophysiological profiles may optimize clinical outcomes.

Objective: To compare the effects of eccentric cycling (ECC), concentric cycling (CON), and standard care (CTL) on cardiopulmonary capacity, respiratory health, and quality of life (QoL) in patients with chronic kidney disease (CKD). Methods: Thirty-one CKD patients were divided into the CTL, CON, and ECC groups. The CON and ECC groups participated in 8-week, 24-session cycling programs. Outcomes were assessed through cardiopulmonary exercise tests, respiratory function tests, and the 36-Item Short Form Survey Instrument questionnaire. Results: The ECC group achieved significant improvements in maximal oxygen uptake, while the CTL group showed a decline. For oxygen uptake efficiency slope, significant changes were observed only in the ECC group, with a group-by-time interaction effect compared to CTL. Furthermore, the ECC group demonstrated the most significant increase in diaphragm movement and a significant increase in diaphragm thickness, with comparisons indicating that ECC outperformed both CTL and CON. Regarding QoL, the ECC group exhibited significantly greater improvements in Physical Component Summary and Mental Component Summary, with statistically significant differences compared with the CTL and CON groups. Conclusion ECC is a low-effort, high-benefit exercise modality that significantly enhances cardiopulmonary fitness, respiratory function, and QoL in patients with CKD.

Objective: To assess maladaptive beliefs about low back pain (LBP), valid and reliable measurement tools are required. Although some tools exist to assess them, the Low Back Pain-related Beliefs Screening Tool (LBP-BST) was developed in order to explore all different categories of misbeliefs in individuals chronic low back pain (CLBP). This study aimed to evaluate the main psychometric properties of both the short and long versions of the revised LBPBSTv2. Methods: A total of 108 patients with CLBP completed the LBP-BSTv2 to assess its potential floor/ceiling effects, internal consistency, and construct validity. The latter was evaluated by comparing scores with the Back Beliefs Questionnaire (BBQ). Test-retest reliability was assessed in 47 of the participants one week later. Results: No floor or ceiling effects were observed. The short and long versions of the LBPBSTv2 showed strong construct validity, with significant correlations with BBQ scores. Internal consistency was acceptable to good (Cronbach’s alpha: 0.77–0.84), and test-retest reliability was high (intraclass correlation coefficient: 0.76–0.81). Conclusion The LBP-BSTv2 is a valid and reliable tool for assessing maladaptive beliefs in patients with CLBP. Its integration into clinical practice could help healthcare professionals identify and address unhelpful beliefs that may hinder rehabilitation. Further research is needed to confirm its usefulness in tracking changes over time and guiding individualized interventions and to study other psychometric properties such as responsiveness.

Objective: To investigate the effects of social restrictions imposed during the coronavirus disease 2019 (COVID-19) pandemic on postoperative functional recovery in patients who underwent surgery for degenerative musculoskeletal disorders. Methods: This longitudinal prospective cohort study included 291 patients categorized into pre-pandemic (surgery in 2018), early pandemic (2019), and late-pandemic (2020) groups based on their 1-year recovery period. The primary outcome was improvement in locomotive syndrome (LS) status 1 year after surgery. We analyzed the association between social limitations and LS improvement using multivariate logistic and segmented regression analyses. Results: The late-pandemic group exhibited the lowest LS improvement rate (50.6%) and the highest prevalence of postoperative social contact limitations (61.0%). Multivariate analysis identified the absence of postoperative social contact limitation as a highly potent independent predictor of LS improvement (odds ratio, 10.01; 95% confidence interval, 5.40–19.34; p<0.01). Segmented regression analysis revealed a time lag: social contact limitations peaked in March 2020, whereas the decline in LS improvement rates began in October 2020. Conclusion Prolonged social restrictions negatively impacted functional recovery, particularly during the late phase of the pandemic. Social participation, specifically direct social contact, could be a critical and independent component of postoperative rehabilitation. These findings underscore the need to integrate psychosocial assessments into standard postoperative care to optimize patient outcomes.

Objective: To develop and validate a clinically actionable prediction model for postoperative pulmonary complications (PPCs) in cardiac surgery patients, focusing on modifiable preoperative risk factors amenable to targeted optimization. Methods: In this prospective observational cohort study, 492 adults undergoing open-chest cardiac surgery between August 15, 2023 and December 31, 2023 were analyzed. Prespecified predictors included gas exchange variables, pulmonary function, inspiratory muscle strength, and physical performance. Univariable and multivariable logistic regression analyses were used to develop the prediction model. Discrimination was assessed by the area under the receiver operating characteristic curve (AUC). Results: A total of 90 patients (14.1%) developed PPCs after surgery. Five independent predictors were identified: elevated arterial PaCO2 (odds ratio [OR] 1.12, 95% confidence interval [CI] 1.00–1.26), oxygen desaturation (SpO2<93%) (OR 12.47, 95% CI 3.51–48.13), reduced gait speed (OR 0.17, 95% CI 0.04–0.71), lower FEV1/FVC ratio (OR 0.96, 95% CI 0.92–1.00), and diminished inspiratory muscle strength (MIP % predicted) (OR 0.96, 95% CI 0.92–0.99). The model demonstrated good discriminative ability with an AUC of 0.86 (95% CI 0.80–0.93) in the training cohort and 0.87 (95% CI 0.74–0.93) in the validation cohort. Conclusion This parsimonious model achieved high predictive accuracy using five modifiable physiological variables. By targeting abnormalities in gas exchange, pulmonary mechanics, muscle strength, and functional reserve, the model offers a practical tool to guide individualized prehabilitation strategies for reducing PPC risk in cardiac surgery patients.

Objective: To examine back muscle activity and fatigue behavior in female patients with degenerative thoracolumbar kyphosis (DTK) using high-density surface electromyography (HDSEMG) and evaluate the effects of using a soft spinal orthosis. Methods: Seven female participants with DTK (mean age: 73.6 years) were assessed during static standing and a weighted holding task with and without a soft spinal orthosis. HDSEMG signals were obtained from the lumbar erector spinae using a 64-electrode array. Time to fatigue (TTF), spatial displacement, and directional consistency of muscle activation were analyzed using the spatial center of activity (SCoA) and circular variance (CV). Results: Orthosis use significantly reduced the sagittal vertical axis and low back pain. TTF was significantly prolonged during the weighted holding task with the orthosis (p=0.012), indicating delayed fatigue onset. SCoA displacement was significantly reduced in both tasks (p<0.001), whereas CV analysis demonstrated improved directional consistency of muscle activation. Conclusion HD-SEMG revealed early fatigue onset and unstable muscle activation patterns in patients with DTK, particularly during load-bearing tasks performed without orthotic support. Orthosis used improved endurance and neuromuscular efficiency by reducing spatial and directional variability in muscle recruitment. These findings underscore the utility of HDSEMG for elucidating the neuromuscular pathophysiology of DTK and support the use of spinal orthoses as a conservative treatment approach.

Objective: To explore whether ultrasonographic measurements of tongue thickness are associated with swallowing function and related clinical domains in patients with amyotrophic lateral sclerosis (ALS), this feasibility study was conducted. Few studies have examined the usefulness of ultrasonographic tongue thickness measurement in patients with ALS, but its association with physiological measures remains unclear. Methods: Ten patients with ALS underwent tongue thickness measurement using ultrasonography. Clinical assessments including the Korean version of the ALS Functional Rating Scale-Revised (K-ALSFRS-R), Functional Oral Intake Scale (FOIS), Eating Assessment Tool-10 (EAT-10), Dysphagia Handicap Index, Korean version of the Swallowing Quality of Life Questionnaire, Mini Nutritional Assessment–Short Form (MNA-SF), handgrip strength, and bioelectrical impedance analysis for skeletal muscle index (SMI) were performed. Swallowing physiology was evaluated using the Modified Barium Swallow Impairment Profile (MBSImP), Penetration-Aspiration Scale. Simple and partial Pearson’s correlation analyses as well as univariate regression were performed with adjustments for age, sex, and body mass index (BMI). Results: Tongue thickness showed significant associations with multiple functional and systemic measures in the unadjusted analyses, including FOIS, EAT-10, MNA-SF, BMI, SMI, K-ALSFRS-R. After adjustment, the most consistent associations were observed with the MBSImP oral, pharyngeal, and combined phase scores. Conclusion Tongue ultrasonography may serve as a radiation-free method to preliminarily assess bulbar involvement in ALS. Tongue thickness was most specifically associated with dysphagia outcomes, particularly MBSImP. Given the feasibility design and small sample size, larger longitudinal studies are warranted to confirm its clinical utility in monitoring the progression of dysphagia in patients with ALS.
