Article Abstract
This study examines the relationship between stopping a planned gait initiation due to sudden environmental changes and maintaining body stability. Using a gait initiation version of the Stop Signal Task (SST), we studied changes in anticipatory postural adjustments (APAs) during gait initiation and suppression. We found that trial-level variables, such as the time to start or stop stepping, interacted with biomechanical factors like the center of mass displacement relative to the base of support affecting performance. A critical biomechanical threshold was identified, beyond which stopping movement was unlikely. These findings highlight the strong link between limb action control and body equilibrium, offering a framework within a motor control paradigm. By integrating biomechanical elements, the model effectively simulates real-life scenarios, identifying key variables for studying neural correlations between action and postural control, and aiding in the development of injury prevention and rehabilitation tools for individuals with movement and posture impairments.

Purpose: This study aimed to investigate foot kinematics during gait in individuals with idiopathic clubfoot initially treated with the Ponseti method, focusing on clubfoot-specific deformities, to improve the understanding of posttreatment functional impairments.
Methods: In this prospective cohort study, 23 patients with treated idiopathic clubfoot (34 feet) were compared with 15 age-matched healthy controls (30 feet). Gait analysis was performed using the Heidelberg Foot Model.

Introduction: Exercising upright can promote rehabilitation and reduce the risk of cardiorespiratory and musculoskeletal complications from prolonged sitting. Seated Active Arm Passive Leg Exercise (AAPLE) offers cardiovascular benefits; however, no commercially available device currently enables fully supported, upright AAPLE. The AAPLEwalk device transitions wheelchair users from sitting to standing, facilitating gait-like movements at varying intensities.

Background: Increasing balance and stability, along with efficient locomotion, is a high-priority goal of physical rehabilitation after limb loss in order to facilitate effective participation in society. Research in the general population suggests that the ability to walk fast is correlated to good performance in balance tests. However, it is unclear if and how prosthesis use influences this correlation.

Background: Cerebral palsy (CP) often presents with lower limb torsional deformities that affect gait and mobility. Clinical assessments typically rely on static physical examinations, but discrepancies arise when compared with dynamic gait kinematics. Understanding the relationship between clinical assessments, including imaging, and gait analysis is essential for accurate diagnosis and treatment planning.
