Article Abstract
To determine the influence of environmental complexity on cognitive-motor interaction during wheelchair propulsion. Fourteen participants completed two single- to dual-task trials of Serial-7 Subtraction Task and four environments varying in complexity. Differences in cognitive and motor function were determined through paired samples -tests and percent changes (dual-task costs [DTCs]) were calculated. Within-subjects, repeated-measures ANOVAs were performed to determine differences in DTCs across environments. Cognitive function was maintained from the single- to dual-task trial in all environments ( ≥ 0.16) and yielded similar DTCs across environments ( = 0.80). Compromised motor function was observed in all environments ( ≤ 0.03) and yielded similar DTCs across environments ( ≥ 0.37). Wheelchair propulsion is attentionally demanding; however, environmental complexity did not exacerbate cognitive or motor dual-task costs.

Minimizing repetitive strain (RS) is a key recommendation from clinical practice guidelines for preservation of upper limb. Propulsion force, which is required to overcome wheel rolling resistance (RR), is a major source of RS. A drum-based RR test method has been developed but has not been directly validated against propulsion forces.

Background: Wheelchair propulsion strategies vary widely among individuals with complete spinal cord injury (SCI), yet research typically focuses on differences between injury levels rather than variability within the same level. This study investigated how physical activity (PA) level and time since injury affect wheelchair propulsion biomechanics in individuals with identical T12/L1 SCI classification.
Methods: Eleven participants with complete T12/L1 SCI performed wheelchair propulsion at maximum and self-selected speeds.

Background: Manual wheelchair propulsion is often associated with pain in the upper extremities. Recording spatio-temporal parameters can optimize movement patterns and prevent injuries. This study compares a marker-based camera system with inertial measurement units to validate their use in wheelchair propulsion on a test stand.

Wheelchair racing is one of the major competitive parasports for athletes with disabilities. Intensive training is necessary to acquire a unique wheelchair propulsive strategy that can be regarded as maximizing the residual function for athletes. We sought to elucidate the mechanisms underlying the unique modality of wheelchair racing performance based on a comprehensive biomechanical analysis.

Introduction: Wheelchair basketball is a highly dynamic sport that requires optimized propulsion techniques, sprint performance, and fatigue resistance. Understanding the biomechanical differences between age groups is crucial for potential estimation and training optimization. This study aimed to analyze the impact of age on sprint performances by comparing junior and senior wheelchair basketball players, while also identifying factors influencing sprint performances beyond age, such as experience, wheelchair characteristics, and classification.
