Knee osteoarthritis (KOA) can have more pronounced effects on joint position sense (JPS) accuracy and gait characteristics. The aim of this study is to investigate the association between lower limb JPS and different aspects of gait pattern including gait asymmetry and variability and spatiotemporal coordination in individuals with bilateral KOA. In this cross-sectional study, lower limb JPS of 43 individuals with bilateral KOA (mild and moderate) were measured.

Patients with radiographic axial spondyloarthritis (r-axSpA) experience a higher prevalence of fragility fractures, though the pathophysiology of osteoporosis associated with this disease remains poorly understood. The objective of this study was to evaluate the histomorphometric data in r-axSpA patients. Male r-axSpA patients up to 55 years old were enrolled in this cross-sectional study.

Introduction: Accurate joint moment analysis is essential in biomechanics, and the integration of direct collocation with markerless motion capture offers a promising approach for its estimation. However, markerless motion capture can introduce varying degrees of error in tracking trajectories. This study aims to evaluate the effectiveness of the direct collocation method in estimating kinetics when joint trajectory data are impacted by noise.

Given the higher fall risk and the fatal sequelae of falls on stairs, it is worthwhile to investigate the mechanism of dynamic balance control in individuals with knee osteoarthritis during stair negotiation. Whole-body angular momentum ([Formula: see text]) is widely used as a surrogate to reflect dynamic balance and failure to constrain [Formula: see text] may increase the fall risk. This study aimed to compare the range of [Formula: see text] between people with and without knee osteoarthritis during stair ascent and descent.

Background/objectives: The active straight leg raise requires intricate coordination between the hip, knee, pelvis, and spine. Despite its complexity, limited research has explored the relationship between lower limb raising velocity and trunk muscle motor control during an active straight leg raise in healthy individuals. This study aimed to explore the potential effects of increased lower limb raising velocity on core muscle contractions during active straight leg raises.
