This study aimed to (1) compare postural sway patterns between individuals with chronic low back pain (CLBP) and asymptomatic controls, (2) evaluate correlations severity stability variables, (3) assess the interaction effects of age, BMI, severity, disability on under eyes-open eyes-closed conditions. Postural (sway area, velocity, CoP displacement) was assessed in 88 CLBP patients controls using a stabilometric platform. Pain (VAS) (ODI) were recorded alongside demographic data. Statistical analyses included t-tests, Pearson's correlations, ANOVA explore group differences, effects. Chronic exhibited significantly greater across all conditions, larger area (16.80 ± 6.10 cm2 vs. 11.50 4.10 cm2, p = 0.004) higher velocity (4.10 1.40 cm/s 2.90 1.00 cm/s, 0.009) correlated (r 0.52, 0.003) displacement 0.57, 0.002).

Head engagement during visuomotor tracking is determined by postural demands and aging

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Фев. 25, 2025

Abstract Vision is important for various tasks, from visually tracking moving objects to maintaining balance. People obtain visual information through eye movements performed either alone or in combination with head movements. Even when isolated can accommodate the amplitude of desired gaze shift, humans still perform movements, as they provide additional sensory signals that be integrated retinal input resulting improved estimates. However, also create mechanical torques and attenuate vestibular processing could disturb We, therefore, here examined whether engagement determined by postural requirements performing a task. Young participants tracked target horizontally along different amplitudes, while were seated, standing on firm an unstable surface. Our results showed stronger than sitting, but no systematic differences found between surfaces. To further explore interplay demands, we conducted second experiment where young older similar task, now allowed move their instructed limit Both accuracy sway increased engaging head. When asked both age groups engaged minimally, more pronounced challenging postures. naturally, younger adults reduced demanding We suggest facilitate tracking, limited preserve

Ageing changes the proprioceptive contribution to balance control under different types of mastoid vibration: A cross‐sectional study

Experimental Physiology, Год журнала: 2025, Номер unknown

Опубликована: Март 11, 2025

Abstract Ageing‐related sensory deteriorations are significantly associated with poor balance control among older individuals, resulting in a higher risk of falling dark environment. In particular, the proprioceptive system plays critical role maintaining balance. This study aimed to determine how ageing‐related contributed during standing under various conflicts. Twenty healthy, active adults (10 young and 10 older) participated this study. Balance was quantified through two organization test conditions (SOT‐1: unblindfolded standing; SOT‐2: blindfolded standing). Mastoid vibration (MV) applied unilaterally (Uni) or bilaterally (Bi) mastoid processes, for perturbing vestibular inputs. A total six trials were assigned each participant random order. Dependent variables included traveling route (TR), performance index (PI) sample entropy (SaEn) anterior–posterior (AP) medial–lateral (ML) directions. Our results showed that (1) compared without MV, applying MV increased TR_AP (Uni: P = 0.003; Bi: < 0.001) TR_ML 0.009; 0.011) all participants (2) application Uni Bi PI_AP, PI_ML, SaEn_AP SaEn_ML when SOT‐1 SOT‐2 ( 0.05); (3) demonstrated PI_ML than standing. indicated potential imbalance attributed even healthy adults. Furthermore, unilateral had stronger effect on disturbing ML bilateral MV.

Purpose Baduanjin represents an affordable and secure method of exercising both the mind body, has been observed to enhance balance in older adults. Nevertheless, existing research on impact various functions is still insufficient, optimal dosage parameters for performing exercises have not studied. Methods To conduct a systematic review meta-analysis, five English databases three Chinese were performed. Relevant studies searched by GOOGLE SCHOLAR, Web Science, Cochrane, Embase, Pubmed, CNKI, SinoMed, WangfangMed using “Baduanjin” “balance.” Subgroup analyses conducted investigate influence different exercise outcomes. Meta-regression was employed identify potential moderating factors. The Physical Therapy Evidence Database (PEDro) scale used quality assessment. Results A total 40 included analysis, while majority report promising outcomes, overall these relatively low. results meta-analysis showed significantly enhanced static (SMD = 0.87, 95%CI: 0.69–1.05), dynamic 0.85, 0.50–1.19), proactive −1.00, −1.33–−0.67) test battery 1.04, 0.81–1.28) Additionally, findings indicated notable reduction risk falls −2.19, −3.35–−1.04) improvement fall efficacy (SMD: 0.57, 0.36–0.78). Conclusion demonstrated improve reduce Studies found that significant gains begin be achieved with minimum 12 weeks practice 30–49 min practice, 5–7 times per week, works best developing balances. However, most limited lack blinding follow-up visits, there insufficient number short-term or long-term establish complete robustly.

Degenerative loss of muscular strength, especially in the knee extensors and flexors, is a hallmark aging that severely compromises functional independence elevates fall risk among older adults. Precise quantification strength therefore essential for effective diagnosis intervention geriatric rehabilitation. Although isokinetic dynamometry remains reference standard objective measurement, its cost, bulk, operational complexity hinder applicability real-world clinical community settings. Portable isometric testing devices offer practical alternative, but rigorous validation studies are needed. This study aimed to establish test-retest reliability concurrent validity Leg Strength Analyzer (IB-LS), compact device developed by InBody Inc., against gold-standard dynamometer (CSMI Humac Norm) sample community-dwelling Twenty-one adults (mean age: 65.10 ± 4.56 years; 11 men, 10 women) were recruited from senior centers. Participants underwent standardized bilateral extension flexion using both IB-LS CSMI systems. The protocol involved three maximal voluntary contractions per movement limb, performed on same day assessment. A follow-up session was conducted 24 hours later 17 participants, during which at 60°/s performed. Intraclass correlation coefficients (ICCs) calculated evaluate intra-device inter-device validity.

Frontiers in Psychiatry, Год журнала: 2025, Номер 16

Опубликована: Июнь 3, 2025

Objective This study aimed to (1) assess the associations among cognitive function, fear of falling, and balance in community-dwelling older adults; (2) identify key predictors performance; (3) examine implications for fall prevention strategies. Methods Eighty-four adults (≥65 years) residing independently community were recruited during outpatient visits. Cognitive function was assessed using Saint Louis University Mental Status (SLUMS), falling measured with Falls Efficacy Scale-International (FES-I), performance evaluated Berg Balance Scale (BBS). Physical activity, demographic factors, history also recorded. Results Bivariate correlations showed that higher associated better (r = 0.45, p 0.014), while greater linked poorer -0.52, 0.003). A hierarchical regression model revealed (β 0.32, 0.002) -0.44, &lt; 0.001) significant performance, even after controlling age, gender, physical history.
