Exploring the challenges of avoiding collisions with virtual pedestrians using a dual-task paradigm in individuals with chronic moderate to severe traumatic brain injury.

Background: Individuals with a moderate-to-severe traumatic brain injury (m/sTBI), despite experiencing good locomotor recovery six months post-injury, face challenges in adapting their locomotion to the environment. They also present with altered cognitive functions, which may impact dual-task walking abilities. Whether they present collision avoidance strategies with moving pedestrians that are altered under dual-task conditions, however, remains unclear.

Understanding the relationship between psychological factors and important health outcomes in older adults with hip fracture: A structured scoping review.

Background: Recovery after hip fractures is often poor despite successful surgeries and rehabilitation programs, which suggests factors beyond the physical might be at play. The purpose of this study was to provide an overview of existing literature on the role of psychological factors in older adults' recovery after hip fracture.

Methods: A scoping review directed by the modified guidelines of Arksey and O'Malley was carried out to systematically search the peer-reviewed literature until Dec 2020.
