Usability evaluation of a self-management mobile application for individuals with a mild traumatic brain injury.

Objective: Mild traumatic brain injuries (mTBIs) are common and may result in persisting symptoms. Mobile health (mHealth) applications enhance treatment access and rehabilitation. However, there is limited evidence to support mHealth applications for individuals with an mTBI. The primary purpose of this study was to evaluate user experiences and perceptions of the Parkwood Pacing and Planning™ application, an mHealth application developed to help individuals manage their symptoms following an mTBI. The secondary purpose of this study was to identify strategies to improve the application. This study was conducted as part of the development process for this application. Methods: A mixed methods co-design encompassing an interactive focus group and a follow-up survey was conducted with patient and clinician-participants (n = 8, four per group). Each group participated in a focus group consisting of an interactive scenario-based review of the application. Additionally, participants completed the Internet Evaluation and Utility Questionnaire (UQ). Qualitative analysis on the interactive focus group recordings and notes was performed using phenomenological reflection through thematic analyses. Quantitative analysis included descriptive statistics of demographic information and UQ responses. Results: On average, clinician and patient-participants positively rated the application on the UQ (4.0 ± .3, 3.8 ± .2, respectively). User experiences and recommendations for improving the application were categorized into four themes: simplicity, adaptability, conciseness, and familiarity. Conclusion: Preliminary analyses indicates patients and clinicians have a positive experience when using the Parkwood Pacing and Planning™ application. However, modifications that improve simplicity, adaptability, conciseness, and familiarity may further improve the user's experience.

Completing an interdisciplinary outpatient intervention improves patient rehabilitation goals following a mild traumatic brain injury.

BACKGROUND: Individualized and interdisciplinary rehabilitation programs are recommended following a mild traumatic brain injury (mTBI), but often have long waitlists. Accordingly, innovative evidence-based programs are needed. OBJECTIVES: The first objective of this study was to determine the number and types of rehabilitation goals chosen by individuals completing an interdisciplinary outpatient rehabilitation intervention (BrainEx90) for persisting symptoms following an mTBI. The second objective was to investigate whether completing BrainEx90 or choosing specific types of goals influenced performance and satisfaction ratings of these goals. METHODS: 217 individuals (44.4 ± 13.5 years old) with persisting symptoms following an mTBI completed BrainEx90, a 16-session interdisciplinary group outpatient rehabilitation intervention at Parkwood Institute between November 2013 and September 2019. Performance and satisfaction ratings of self-identified goals before and after BrainEx90 were assessed using the Canadian Occupational Performance Measure, and changes in ratings were analyzed using a linear mixed effects model. RESULTS: 1008 goals were identified and categorized as: productivity (45%); leisure (37%); and self-care (18%). Satisfaction ratings were significantly higher for all goal types following BrainEx90. Satisfaction with self-care goals improved significantly more than leisure [t(151) = 3.24, p < .01] and productivity [t(144) = 2.97, p < .01] goals. Performance ratings were also significantly greater following BrainEx90 [2.4, 95% CI [2.27, 2.53], p < .01)]. CONCLUSION: Performance and satisfaction of self-identified rehabilitation goals significantly improved following BrainEx90. Satisfaction with self-care goals demonstrated the greatest improvements, yet the most identified goal type was productivity.

Performing more than 20 purposeful gameplay headers in a soccer season may alter autonomic function in female youth soccer players.

This study evaluated the effects of cumulative purposeful soccer heading on autonomic nervous system function in 22 female youth soccer players (13.3 ± 0.9 years). A 10 minute electrocardiogram recording was collected at baseline and following the 20 game season (post-season) to calculate measures of heart rate variability (HRV), including standard deviation of the normal-normal intervals, total power, high frequency (HF), low frequency (LF), LF:HF, normalized HF and normalized LF. Participants were categorized into low- (<20 headers per season; n = 13) and high- (>20 headers per season; n = 9) exposure groups. Mann-Whitney U tests demonstrated no significant differences between groups for any HRV metric. However, the increased normalized LF power (low exposure 8.67 and high exposure -31.17, respectively; r = 0.35) and LF:HF power (-6.39 and 15.80, respectively; r = 0.35), between groups had moderate practical significance. Therefore, female youth players who perform more than 20 purposeful headers during a soccer season may exhibit altered autonomic function.
