Objective: Behavioral changes following moderate to severe traumatic brain injury (MSTBI) are common and can include agitation or aggression, reduced arousal or apathy, and inappropriate sexual behavior. These changes can negatively affect recovery, function, and quality of life. Pharmacological and nonpharmacological interventions are often used to address these challenges; however, there is limited evidence regarding the effectiveness of these treatments.

Introduction: Moderate to severe traumatic brain injury (MS-TBI) commonly causes disruption in aspects of attention due to its diffuse nature and injury to frontotemporal and midbrain reticular activating systems. Attentional impairments are a common focus of cognitive rehabilitation, and increased awareness of evidence is needed to facilitate informed clinical practice.

Methods: An expert panel of clinicians/researchers (known as INCOG) reviewed evidence published from 2014 and developed updated guidelines for the management of attention in adults, as well as a decision-making algorithm, and an audit tool for review of clinical practice.

Introduction: Concussion/mild traumatic brain injury (mTBI) often presents initially with disabling symptoms that resolve, but for an unfortunate minority some of these symptoms may become prolonged. Although research into diagnosis and interventions for concussion is increasing, study quality overall remains low. A living systematic review that is updated as evidence becomes available is the ideal research activity to inform a living guideline targeting clinicians and patients.

Objective: This study investigated psychometric properties of the Motivation for Traumatic Brain Injury Rehabilitation Questionnaire (MOT-Q), the Brain Injury Rehabilitation Trust Motivation Questionnaire-Self (BMQ-S), the Rehabilitation Therapy Engagement Scale-Revised (RTES-R), and the BMQ-Relative (BMQ-R) in individuals with an acquired brain injury (ABI).

Design: Thirty-nine patients with an ABI completed the MOT-Q, BMQ-S, measures of apathy (Apathy Evaluation Scale-Self), insight (Patient Competency Rating Scale-Self), depression, and anxiety (HADS). Twenty clinicians provided 39 ratings using the RTES-R, BMQ-R, measures of patient apathy (Apathy Evaluation Scale-Clinician) and insight (Patient Competency Rating Scale-Clinician).

Purpose: Therapists use motor learning strategies (MLSs) to structure practice conditions within stroke rehabilitation. Virtual reality (VR)-based rehabilitation is an MLS-oriented stroke intervention, yet little support exists to assist therapists in integrating MLSs with VR system use.

Method: A pre-post design evaluated a knowledge translation (KT) intervention incorporating interactive e-learning and practice, in which 11 therapists learned how to integrate MLSs within VR-based therapy.

Background: Inpatient rehabilitation with patients who have sustained an acquired brain injury (ABI), including traumatic brain injury (TBI), focuses on improving performance in activities of daily living (ADLs). Although not studied to date in patients with ABI/TBI, Task Analysis (TA) integrates assessment and the prompting/cueing levels required to complete various tasks, with the goal to achieve effective skill acquisition and rehabilitation planning. TA has demonstrated efficacy in teaching life skills in individuals with developmental disabilities and in this study is applied to teaching ADL skills in ABI/TBI rehabilitation.

Background: Despite increasing evidence for the effectiveness of virtual reality (VR)-based therapy in stroke rehabilitation, few knowledge translation (KT) resources exist to support clinical integration. KT interventions addressing known barriers and facilitators to VR use are required. When environmental barriers to VR integration are less amenable to change, KT interventions can target modifiable barriers related to therapist knowledge and skills.
