Purpose: To examine the feasibility and acceptability of a 6-week peer-based walking intervention for adults with moderate-to-severe TBI with telehealth supports. Materials and methods: Pre-post feasibility trial with 18 community-dwelling adults (10 men; 8 women) with moderate-to-severe TBI aged 21-61 years (M = 40.6, SD = 11.3). Feasibility ou...

Background: Graded exertion testing (GXT) is an important tool for concussion management, as it is used to personalize post-concussion exercise prescription and return athletes to sport. However, most GXT requires expensive equipment and in-person supervision. Purpose: Our objective was to assess the safety and feasibility of the Montreal Virtua...

Primary objective: To explore the experiences of program mentors, participants, and employees involved in a peer-based physical activity (PA) program for adults with moderate-to-severe TBI, being piloted by a community fitness center, to develop the program as a measurable intervention. Research design: We adopted an exploratory case study appro...

Research Objectives Promoting physical activity (PA) after moderate-to-severe traumatic brain injury (TBI) is challenging due to elevated PA barriers (e.g., transportation, accessibility, endurance, self-consciousness) and COVID-19-related restrictions leading to the closure of community fitness centres. There was a need to create an outdoor walkin...

Introduction: Persistent post-concussion symptoms following a mild traumatic brain injury (mTBI) can impact function and participation of adults. Physical activity is recommended to reduce symptoms and foster return to normal activities. Adults with a mTBI may have personal factors or experience accessibility issues restricting physical activity....

Objective: This scoping review mapped the current evidence about community-based physical activity (PA) interventions for individuals with moderate-to-severe traumatic brain injury (TBI) and identified the reported health-related outcomes, measurement tools used, and considerations given to sex and gender. Methods: Searches were conducted in six...

Introduction: There is limited scientific evidence about the optimal content and parameters of physical activity (PA) interventions for rehabilitation outpatients with persisting symptoms of a mild traumatic brain injury (mTBI). Clinicians have thus had to develop services based on their expertise, feasibility and patient needs. Objectives: This st...

Background Physical activity interventions have been shown to be an effective therapeutic approach to improve symptoms and reduce recovery time after a mild traumatic brain injury. Service providers from a specialized traumatic brain injury outpatient rehabilitation program recognized the need to ensure their physical activity intervention integrat...

Objective(s) To map and synthesize evidence about community-based physical activity (PA) interventions for individuals with moderate-severe traumatic brain injury (m-s TBI) by asking the questions: what are the characteristics of community-based PA programs for individuals with m-s TBI; what are the reported health-related outcomes and measurement...

Objective: To document the characteristics, measured outcomes, and effectiveness of physical activity (PA) interventions designed to improve health-related outcomes in individuals with a mild traumatic brain injury (mTBI) to assist in rehabilitation quality improvement efforts of a TBI rehabilitation program. Methods: A scoping review following...

Background Long-term physical, cognitive, and psychosocial problems resulting from moderate to severe traumatic brain injury (TBI) can prevent individuals from returning to preinjury lifestyles because of significant challenges with employment, leisure, and relationships. While physical activity (PA) is proposed as a cost-effective method to allevi...

Introduction Traumatic brain injury (TBI) is a major public health problem, and it is estimated that 85% of TBIs are diagnosed as mild and are commonly referred to as a concussion. In adults, symptoms are expected to resolve within 10–14 days after the injury, but up to 15% of individuals continue to have symptoms beyond this period. Recent clinica...
