Summary: Patients with unilateral knee osteoarthritis (KOA) exhibit asymmetries in muscle strength, proprioception, biomechanics, and postural stability. Muscle strength, proprioception, and postural stability are significantly associated variables, and changes in these variables should be considered in KOA prevention and rehabilitation.

Summary: This study introduces a new approach for calculating virtual time-to-contact (VTC) called directional VTC, which expands the evaluation of balance to include temporal, spatial, and control aspects. Through three case studies, preliminary results not only provided a closer look at balance control with multiple aspects, but also showed the effects of neurological diseases or challenging standing environments on balance.

Summary: In this study, a mathematical model is developed to study the essential sways of stance caused by rotational movements about the ankle and hip joints. The model uses a nonlinear feedback control law to stabilize the upright stance and eliminate internal torques induced by postural movement constraints. Numerical simulations demonstrate the effectiveness of the proposed control method for postural balancing.

Summary: This study aimed to investigate the postural strategies used by archers to enhance stability and identify characteristics that may contribute to better performance. The results showed that elite archers more frequently and earlier triggered postural adjustments before the string release compared to sub-elite archers. This study reveals the ability of archers to optimize postural stability by anticipatory postural adjustments triggered prior to string release.

Summary: The purpose of this study was to investigate the correlations of lower extremity muscle strength, proprioception, and tactile sensation to postural stability among older adults with and without sensory deficits, and to explore sensory reweighting among the two populations. The results showed that older adults with sensory deficits had lower BBS scores and higher proprioception thresholds, while lower extremity muscle strength and proprioception were correlated with BBS among older adults without sensory deficits. Older adults with sensory deficits have poorer proprioception and postural stability, and somatosensory reweighting occurs from proprioception to tactile sensation among them.

Summary: This study investigated the relationship between neurocognitive performance and dynamic postural stability in healthy collegiate athletes. The results showed that athletes with poorer neurocognitive performance had higher vertical acceleration and lower anteroposterior acceleration. This suggests that neurocognitive performance may influence the stability strategies adopted by athletes during postural tasks.

Summary: This study found that the performance of the MediPost sensor in balance testing is significantly better than the force plate in patients with unilateral vestibular dysfunction and healthy individuals. The sensitivity and specificity of the MediPost sensor were best in all conditions, indicating its potential for use in clinical balance assessments.

Summary: This study investigated the prevalence of floating toe in children and its relationship with static postural stability, finding that the floating toe score was significantly higher in the eyes-closed condition than in the eyes-open condition, suggesting that ground contact of the toes is not directly related to static postural stability in children.

Summary: The purpose of this study was to establish a novel and clinically feasible assessment of lower-extremity dexterity for patients with Parkinson's disease (PD), and to validate its criterion and construct validity. The results showed significant relationships between lower-extremity dexterity and measures of gait, mobility, and upper-extremity dexterity. This assessment tool provides a simple and objective way to measure lower-extremity function in PD patients, and has the potential to be implemented in clinical settings.

Summary: This study compared the scaling of postural stability variables between older fallers and nonfallers during gait initiation while stepping over increasing obstacle distances. The results showed that older fallers adopt a more conservative strategy and display increased trunk lean during the swing phase. The pre-toe-off postural stability may be a critical marker for identifying fallers.

Summary: Identification of individuals at high risk for rapid progression of motor and cognitive signs in Parkinson's disease is clinically significant. This study found a relationship between postural instability and greater motor and cognitive deterioration. Baseline features were identified that were associated with future postural instability, allowing for early intervention and management of Parkinson's disease.

Summary: The study investigates the effects of sensory manipulations on locomotor adaptation in younger and older adults. Contrary to expectations, the results show that sensory manipulations did not disproportionately affect older adults. Both younger and older adults were able to adequately reweight sensory information based on environmental constraints, indicating well-functioning neural processes of motor adaptation.

Summary: This study reports the in vivo changes in intradiscal pressure (IDP) using clinically available instrument-assisted spinal manipulation devices and/or spinal mobilization procedures in cats for the first time. The results suggest that a feline model can be used to investigate IDP changes related to spinal manual therapy mechanisms and the dampening effect of viscoelastic properties of spinal tissues on these manipulative forces. Further investigation of IDP changes in this and/or other in vivo animal models is needed to gain better insights into the physiological effects and mechanisms of spinal manual therapy at the intervertebral disc level.

Summary: Our cross-sectional study aimed to investigate joint specificity of concentric muscle torque enhancement after a maximum eccentric contraction for the knee versus ankle joints across two different movement velocities (120(degrees)/s and 180(degrees)/s). Our results show that greater concentric muscle torque enhancement after a maximal eccentric contraction occurs for the ankle plantar flexors versus knee extensors.
