Correlations between plantar pressure and postural balance in healthy subjects and their comparison according to gender and limb dominance: A cross-sectional descriptive study.

BACKGROUND: Lower extremity injuries rank among the most common injuries affecting young population, and numerous factors affect the outcomes of plantar pressure and balance assessment. RESEARCH QUESTION: Does a correlation exist between plantar pressure and postural balance in healthy subjects and are there any difference in the results based on gender and limb dominance? METHODS: This study involved thirty healthy recreationally active young adults (15 females, 15 males). Plantar pressures were analyzed using the MatScan Pressure Mat System, and postural balance was evaluated using Biodex Balance System. All assessments conducted under both static and dynamic conditions. Correlations were tested by Spearman Correlation Coefficient, and comparative tests were performed for gender and limb dominance. RESULTS: Correlations were observed between plantar pressure parameters and balance scores, particularly in the dynamic conditions (p < 0.05). Gender-based differences were noted in plantar pressure parameters (p < 0.05), with females demonstrating improved balance stability scores. No significant differences were found based on limb dominance in plantar pressure and postural balance data (p > 0.05). SIGNIFICANCE: This study provides valuable detailed insights into the existing literature concerning plantar pressure and postural balance assessments within the healthy population. A strong correlation was observed between plantar pressure and postural balance, and the comparisons of these assessments were affected by gender but not by limb dominance. These results could lead the way for better rehabilitation approaches by considering the correlations and differences across diverse populations.

Position paper on how technology for human motion analysis and relevant clinical applications have evolved over the past decades: Striking a balance between accuracy and convenience.

BACKGROUND: Over the past decades, tremendous technological advances have emerged in human motion analysis (HMA). RESEARCH QUESTION: How has technology for analysing human motion evolved over the past decades, and what clinical applications has it enabled? METHODS: The literature on HMA has been extensively reviewed, focusing on three main approaches: Fully-Instrumented Gait Analysis (FGA), Wearable Sensor Analysis (WSA), and Deep-Learning Video Analysis (DVA), considering both technical and clinical aspects. RESULTS: FGA techniques relying on data collected using stereophotogrammetric systems, force plates, and electromyographic sensors have been dramatically improved providing highly accurate estimates of the biomechanics of motion. WSA techniques have been developed with the advances in data collection at home and in community settings. DVA techniques have emerged through artificial intelligence, which has marked the last decade. Some authors have considered WSA and DVA techniques as alternatives to "traditional" HMA techniques. They have suggested that WSA and DVA techniques are destined to replace FGA. SIGNIFICANCE: We argue that FGA, WSA, and DVA complement each other and hence should be accounted as "synergistic" in the context of modern HMA and its clinical applications. We point out that DVA techniques are especially attractive as screening techniques, WSA methods enable data collection in the home and community for extensive periods of time, and FGA does maintain superior accuracy and should be the preferred technique when a complete and highly accurate biomechanical data is required. Accordingly, we envision that future clinical applications of HMA would favour screening patients using DVA in the outpatient setting. If deemed clinically appropriate, then WSA would be used to collect data in the home and community to derive relevant information. If accurate kinetic data is needed, then patients should be referred to specialized centres where an FGA system is available, together with medical imaging and thorough clinical assessments.

Translation and Cross-Cultural Adaptation of the Anterior Cruciate Ligament Donor Site Morbidity Questionnaire Into Turkish.

This study aimed to translate the ACL Donor Site Morbidity (ACL-DSM) questionnaire into Turkish and assess the reliability and validity of the Turkish version of the ACL-DSM questionnaire (ACL-DSM-Tr) among individuals following anterior cruciate ligament (ACL) reconstruction. The process involved forward and back-translation, cultural adaptation, and validation of the ACL-DSM-Tr questionnaire on ninety-nine patients (mean age 30.73 ± 8.55 years). Participants completed ACL-DSM-Tr, International Knee Documentary Committee (IKDC) subjective form, ACL Return to Sport (ACL-RSI), and Forgotten Joint Scale (FJS) questionnaires. The internal consistency, reliability, and validity of the ACL-DSM-Tr were analyzed. The ACL-DSM-Tr demonstrated a high internal consistency (Cronbach's alpha .755) and excellent test-retest reliability (Spearman correlation r = .811, p < .001; Cronbach's alpha .890). The ACL-DSM-Tr score exhibited a strong positive correlation with the IKDC score (r = .690, p < .001) and a moderate positive correlation with the FJS score (r = .535, p < .001). Despite a fair correlation between ACL-DSM-Tr and ACL- RSI subgroup scores, no significant correlation was observed with the ACL-RSI total score (p = .297). In conclusion, the ACL-DSM-Tr demonstrated internal consistency, reliability, and validity in patients with ACL reconstruction. This questionnaire has the potential to yield significant benefits in monitoring patient satisfaction and evaluating the level of comfort experienced at the donor site following ACL reconstruction.

Physical Activity, Kinesiophobia, Pain Catastrophizing, Body Awareness, Depression and Disease Activity in Patients With Ankylosing Spondylitis and Rheumatoid Arthritis: A Cross-Sectional Explorative Study.

OBJECTIVE/AIM: The aim was to compare the levels of physical activity, kinesiophobia, pain catastrophizing, body awareness, and depression in patients with Ankylosing Spondylitis (AS) and Rheumatoid Arthritis (RA) and to explore the associations between these outcomes and disease activity. METHODS: Seventy-eight patients with AS (n = 30) and RA (n = 48) were included. Outcomes were assessed using the International Physical Activity Questionnaire-Short Form, the Tampa Scale of Kinesiophobia, the Pain Catastrophizing Scale, the Body Awareness Questionnaire, and the Beck Depression Inventory. Disease activity levels were determined using the Bath Ankylosing Spondylitis Disease Activity Index for AS and the Disease Activity Score 28 score for RA. RESULTS: AS patients were younger, had a higher proportion of men, and were more physically active than RA patients (p < 0.05). Both groups exhibited high levels of kinesiophobia but low levels of pain catastrophizing, similar body awareness and mild depression scores. Moderate correlations (r ≥ 0.5) were observed between kinesiophobia and depression, body awareness and pain catastrophizing and depression, and pain catastrophizing and disease activity in AS patients. In RA patients, moderate correlations (r ≥ 0.5) were found between kinesiophobia and pain catastrophizing. CONCLUSION: Addressing physical activity, kinesiophobia, pain catastrophizing, body awareness, and depression is important in managing AS and RA patients. Notably, correlations among outcomes differed between groups, with more significant correlations in AS. Further studies are needed to explore these in greater detail.
