The Concussion Challenge Assessment: Development and reliability of a novel gross motor assessment tool for paediatric concussion.

Aims: The aim of this study was to develop a gross motor performance clinical assessment tool, the Concussion Challenge Assessment (CCA), for paediatric concussion populations.

Methods: An expert panel evaluated tasks from the Acquired Brain Injury Challenge Assessment to determine relevant tasks for a paediatric concussion population. These tasks were administered to a convenience sample of 854 healthy youth.

Impact attenuation provided by older adult protective headwear products during simulated fall-related head impacts.

Introduction: While protective headwear products (PHP) are designed to protect older adults from fall-related head injuries, there are limited data on their protective capacity. This study's goal was to assess the impact attenuation provided by commercially available PHP during simulated head impacts.

Methods: A drop tower and Hybrid III headform measured the decrease in peak linear acceleration ( ) provided by 12 PHP for front- and back-of-head impacts at low (clinically relevant: 3.

Standing Versus Stepping-Exploring the Relationships Between Postural Steadiness and Dynamic Reactive Balance Control.

While the literature has characterized balance control during quasi-static and/or dynamic tasks, comparatively few studies have examined relationships across paradigms. This study investigated whether quiet-stance postural steadiness metrics were associated with reactive control parameters (during both stepping and restabilization phases) following a lean-and-release perturbation. A total of 40 older adults participated.
