Background/Objectives: Adverse effects of a sedentary lifestyle on an individual’s overall health are inevitable. With reference to primary-school-aged children, the establishment of effective postural hygiene is critical as it not only promotes optimal musculoskeletal development but also significantly influences their long-term well-being and productivity. This study aimed to develop and internally validate a regularized regression model to predict static postural loading (SPL) in primary school children. Methods: The outcome and predictors of SPL were shortlisted through a systematic review of the literature and expert panels. Data were derived from 258 primary school children. We developed regularized elastic net (EN) and used multiple linear regression (MLR) as a reference. Both models were fitted through five-fold cross-validation with 10 iterations. The grid search technique was used to find the optimal combination of hyperparameters α and λ for the EN. We conducted a permutation importance analysis to obtain and compare predictor rankings for each model. Results: Both models presented a good and comparable fit, with the EN marginally outperforming the MLR in error metrics. Postural risk, sedentary behavior, task duration, and BMI were the most important predictors of SPL in primary school children. Conclusions: The proof of a direct impact of a sedentary lifestyle on children’s overall health is both credible and alarming. Hence, proper identification and management of contributing factors to static postural loading in this age group is critical. In various clinical settings, where the objective is to develop a model that accurately forecasts the outcome, advanced regularized regression methods have evidently shown great performance.

Background: Low back pain (LBP) is a global musculoskeletal ailment. Over the past few years, dry needling (DN) has garnered interest from both physical therapists and patients. Physical therapy commonly employs spinal manipulation to alleviate persistent LBP and other musculoskeletal disorders. The aim of this study was to investigate the effects of spinal manipulation alone and in combination with DN on functional disability and endurance in individuals suffering from chronic nonspecific LBP. Methods: Patients of both genders who had chronic nonspecific LBP and who had not received physical therapy within the last 3 months were included in this single-blind, randomized controlled trial using purposive sampling. All participants were randomly assigned to either the experimental (SMT + DN) or control (SMT alone) group using computer-generated random numbers. The data were analyzed using the Statistical Package for Social Sciences (SPSS) version 23.0. For between-group comparisons, the Mann–Whitney U test was used. A P-value < .05 was considered to indicate statistical significance. Results: The analysis of the difference between the 2 groups revealed that the mean ± standard deviation (SD) for the SMT alone group was 16.09 ± 3.963 at baseline and 12.66 ± 3.801 at 8 weeks, whereas for the DN + ST group, it was 13.67 ± 3.904 at baseline and 10.92 ± 3.534 at 8 weeks, with a P-value of .003. Thus, the RMDQ score improved gradually in both groups, and the mean endurance score reported for the ST group was 2.5 to 4.5, while that reported for the DN + ST group was 3.1 to 5.1. Conclusion: The results of this study showed that both therapies effectively reduced LBP. When comparing the effects of spinal manipulation alone to those of spinal manipulation combined with DN, the latter showed significantly greater benefits.

Context: Defined by several physiological and anatomical contributors, posture is essentially an accurate indicator of health status that is most frequently highlighted by affecting the configuration and operations of internal systems and organs. Quantifying body position has always been highlighted in clinical, academic, and industrial contexts, and various posture analysis approaches have been developed throughout the years. Objectives: This study aims to establish the reliability and validity of several novel observational approaches to postural load assessment and provide an overall view of related trends. Methods: This review was designed and conducted following (PRISMA) guidelines and five databases were surveyed, namely PubMed, Science Direct, CINAHL, Ergonomic Abstracts, and EMBASE, utilizing both generic and specific search terms modified for each database. Articles introducing a novel approach to observational postural load analysis and concepts of reliability and validity of the introduced method were included. Cross-sectional, case-control, experimental, and controlled trial designs were considered. Studies were excluded if they were exclusively based on subjective approaches. The methodological quality of the studies was evaluated using the MacDermid checklist. Similarly, reliability, measurement error, content validity, and criterion validity were assessed using COSMIN (Consensus-based Standards for selecting health Measurement Instruments) boxes B, C, D, and H, respectively. Results: Twenty-five articles were selected for the final review. The studies mainly reported ICC for reliability and r and r2 for validity. The results on the MacDermid quality evaluation tool varied from 38 to 80%, with a mean of 61.60 ± 11.54%. Regarding the COSMIN checklists, the scores were 61.40 ± 10.39%, 59.16 ± 11.35%, 64 ± 16.07%, and 57.12 ± 15.19% for boxes B, C, D, and H, respectively. Some studies did not obtain high scores for specified inclusion and exclusion criteria and appropriate sample size, leading to a moderate quality rating in checklists. Conclusions: Drawing comprehensive conclusions by directly comparing and contrasting observational techniques can be challenging due to their unique strengths, limitations, and inconsistencies. Such variations may arise from the methods’ characteristics, such as the fields, settings, populations, and the evaluated risk factors.

This study aimed to systematically review studies conducted on the application of sonoelastography (SE) to evaluate lumbopelvic muscle stiffness in patients with low back pain (LBP). All relevant articles were retrieved from the available electronic databases, including PubMed, Web of Science, Scopus, EMBASE, Cochrane library, and CINAHL, using the keywords “Sonoelastographyâ€, “Elasticity Imaging Techniqueâ€, “Muscle Stiffnessâ€, “Modulus Elasticityâ€, “Low Back Painâ€. After initial searches, studies that met the inclusion criteria (i.e., published in English and sonoelastography were used to assess lumbopelvic muscle stiffness in both patients with LBP and healthy individuals) were enrolled. Also, any animal research, abstract of the seminar and/or conference, and/or non-English-language article were excluded. The quality of the studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. In total, eight relevant studies were selected for review. Three studies were considered to have excellent quality, and five were considered fair quality using the PEDro scale. All reviewed studies have reported that SE can be considered a non-invasive method for quantifying changes in lumbopelvic muscle stiffness. Muscle stiffness was significantly higher in LBP patients compared to healthy persons, as well as across subgroups of LBP patients in various test postures (PË‚0.05). Only one study was conducted on the reliability of SE in healthy individuals, while another examined the validity of SE imaging. The results of the present systematic review indicated that SE imaging is a reliable and valid tool to identify muscle changes that occur in patients with LBP and evaluate the effects of rehabilitation treatment.

Background: Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia supports the longitudinal arch and absorbs ground reaction forces during the static and dynamic phase(s) of weight-bearing. The purpose of this randomized controlled trial study was to determine the effects of CAD/CAM foot orthoses that were designed based on the dynamic plantar pressure in patients with plantar fasciitis. Methods: This study was performed on 34 patients with plantar fasciitis. Outcomes were compared based on plantar fascia thickness; peak pressure, mean pressure, and maximum force; and pain, activity of daily living, quality of life, and sports activity that were evaluated by ultrasound, plantar pressure platform, and the Foot and Ankle Outcome Score, respectively. The patients were randomly assigned into two groups: the experimental group (CAD/CAM orthoses and night splint) and the control group (night splint only). All data were recorded again after 4 weeks. Results: Pain (P = 0.002) and plantar fascia thickness (P = 0.001) decreased significantly after 1 month of intervention. Activity of daily living (P = 0.044) and quality of life (P = 0.001) showed a significant increase. There was a trend in increasing peak pressure in all masking regions in both groups. The maximum force remarkably reduced in the experimental group in all regions. Conclusions: The results demonstrated that CAD/CAM foot orthoses designed based on dynamic plantar pressure with night splint can reduce the plantar fascia thickness and pain associated with plantar fasciitis and increase the activity of daily living, quality of life, and sports activity.

Background: Virtual reality (VR) is an advanced technique used in physical rehabilitation of neurological disorders, however the effects of VR on balance, gait, and motor function in people with Parkinson’s (PD) are still debated. Therefore, the systematic review aimed to determine the role of VR on motor function, balance and gait in PD patients. Methods: A comprehensive search to identify similar randomised controlled trials was conducted targeting 5 databases including Web of Science, PubMed, CINHAL, Cochrane Library, and Physiotherapy Evidence Database. A total of 25 studies were found eligible for this systematic review, and the methodological assessment of the quality rating of the studies was accomplished using the physiotherapy evidence database scale by 2 authors. Results: Out of the 25 included studies, 14 studies reported on balance as the primary outcome, 9 studies were conducted to assess motor function, and 12 assessed gait as the primary outcome. Most studies used the Unified Parkinson disease rating scale UPDRS (part-III) for evaluating motor function and the Berg Balance Scale as primary outcome measure for assessing balance. A total of 24 trials were conducted in clinical settings, and only 1 study was home-based VR trainings. Out of 9 studies on motor function, 6 reported equal improvement of motor function as compared to other groups. In addition, VR groups also revealed superior results in improving static balance among patient with PD. Conclusion: This systemic review found that the use of VR resulted in substantial improvements in balance, gait, and motor skills in patients with PD when compared to traditional physical therapy exercises or in combination with treatments other than physical therapy. Moreover, VR can be used as a supportive method for physical rehabilitation in patients of PD. However, the majority of published studies were of fair and good quality, suggesting a demand for high quality research in this area.
