Article Synopsis
  • The study aimed to identify tools for measuring diet and nutrition knowledge in adults with spinal cord injuries and disorders (SCI/D) by reviewing literature from 1992-2022.
  • Out of 48 articles reviewed, only five were relevant, revealing a lack of validated nutrition knowledge questionnaires specifically for individuals with SCI/D; most studies focused on either athletes or those with acute injuries.
  • The findings highlight a need for a validated questionnaire that addresses the unique nutritional needs of the SCI/D population, as current tools mostly provide general nutrition knowledge without considering specific conditions.

Introduction: Ecological momentary assessment (EMA) is a methodological approach to studying intraindividual variation over time. This study aimed to use EMA to determine the variability of cognition in individuals with chronic stroke, identify the latent classes of cognitive variability, and examine any differences in daily activities, social functioning, and neuropsychological performance between these latent classes.

Methods: Participants ( = 202) with mild-to-moderate stroke and over 3-month post-stroke completed a study protocol, including smartphone-based EMA and two lab visits.

Background: Digital therapeutics, such as interventions provided via smartphones or the internet, have been proposed as promising solutions to support self-management in persons with chronic conditions. However, the evidence supporting self-management interventions through technology in stroke is scarce, and the intervention development processes are often not well described, creating challenges in explaining why and how the intervention would work.

Objective: This study describes a specific use case of using intervention mapping (IM) and the taxonomy of behavior change techniques (BCTs) in designing a digital intervention to manage chronic symptoms and support daily life participation in people after stroke.
