Objective: Proprioception is the capacity to perceive the position of any body part, either consciously or unconsciously. This sense, in conjunction with the visual and vestibular senses, helps maintain postural balance. This study explores the relationship between postural balance analysis outcomes and proprioceptive sense tractography data. Materials and Methods: Sixty-two healthy individuals were categorized into two groups based on postural balance analysis: the unstable posture group and the stable posture group. Postural sway test measurements, such as sway area, track length, velocity, Romberg quotient, lateral sway, and anteroposterior sway, were recorded for both groups on fixed and moving surfaces over 20 seconds. Using the DSI Studio program, tractography of the proprioceptive sensory pathways was conducted on participants using brain diffusion tensor images (DTI). IBM Statistical Package for the Social Sciences (SPSS) 23.0 software was employed for statistical analysis, with a p-value <0.05 considered statistically significant. Results: Tractography of the unstable posture group revealed increased mean diffusivity (MD) and radial diffusivity (RD) in the brain white matter, superior cerebellar peduncle, and middle cerebellar peduncle, while axial diffusivity (AD) values decreased (p<0.05). There was a notable correlation between the sway area in the unstable and eyes-open positions and the fiber count and fiber percentage in the right inferior cerebellar peduncle. Conclusion: The data suggest impairments in the pathways responsible for carrying unconscious proprioceptive sensations in individuals with unstable posture. [ABSTRACT FROM AUTHOR]

Background: The General Movement Assessment (GMA) is a video analysis method developed by Heinz Prechtl that examines the infant's spontaneous movements. In recent years, although many studies have been performed in preterm infants by applying GMA, few studies have shown the effects of early intervention on GMA.Aims: Current study was planned to determine the acute effects of a single-session early physiotherapy approach on preterm infants' general spontaneous movements, and to reveal the change in Motor Optimality Scale (MOS) score including FMs.Study Design: Prospective, single-blind study.Subjects: Current study was carried out with 32 preterm infants at postterm 12-16 weeks.Outcome Measures: The infants included in the study were videotaped by a physiotherapist during 10-15 min before the physiotherapy session at postterm 12-16 weeks for GMA. After a single physiotherapy session, the same physiotherapist performed the same video footage second time. A blind evaluator assessed the videos taken before and after session and scored Motor Optimality Scale (MOS).Results and Conclusions: There was no statistically significant difference between MOS sub-category and total score of the infants before and after the session (p > 0.05). According to the results of present study, a single-session early physiotherapy intervention did not have an acute effect on the spontaneous movements of preterm infants at postterm 12-16 weeks. Future studies are needed to demonstrate the short and long-term effects of early physiotherapy approaches to risky infants. [ABSTRACT FROM AUTHOR]
