In efforts to assist people who have had a concussion (mild traumatic brain injury), the Parkwood Pacing and Planning™ app has been developed and tested and will be released to the public. The app uses a point system where users have a daily point maximum assigned based on symptom severity with daily activities (recorded by the users). Users can then schedule their daily activities based on their allowed points. The goal is to help users with symptom self-management by facilitating activity planning and pacing.

Patients and clinicians have provided positive feedback on the initial version of the app. Using this as a foundation, the investigators envision enhancing the app to provide a more personalized user experience and to enable further discovery and innovations in the recovery from concussion. This will be accomplished through data analytics and machine-learning techniques, informed by the results of a large-scale research trial. This strategy will be used to customize the point system to facilitate the user with pacing and planning.

At Parkwood Institute, the Outpatient Acquired Brain Injury Program receives approximately 350 referrals per year related to concussion (an increase of 500% since 2010). This program is renowned for its innovative programming, strong ties to brain injury research across the province, and the way that patients are engaged in program design, development and evaluation.

People who experience persistent and disabling problems three months beyond their brain injury are characterized as having "post-concussion syndrome". The list of post-concussion symptoms is long. Some of the most prevalent and debilitating symptoms include severe headaches and fatigue, forgetfulness, blurred vision and dizziness resulting in balance difficulties, poor concentration, sleep disturbances and depression. These symptoms can impact someone's daily functional ability, cause emotional distress and potentially limit their ability to return to work or school, which includes early back to work employment. Further, the impact of these debilitating symptoms can result in the breakdown of the family unit; whereby the patient's recovery is put at risk along with the mental health and financial impact on their family.

While trying to cope with these persistent symptoms, many individuals also experience a lack of post-recovery education and ongoing daily support as to how best to manage their symptoms while they begin to recover. Resting can actually prolong symptoms and lead to more difficulties, while being too active can restart or increase the severity of symptoms. However, health care providers at Parkwood Institute have discovered that patients who learn how to appropriately pace and plan their activities can minimize their symptoms, enhance recovery, and resume activities that had previously been a major part of their lives.

In 2013, the Parkwood Institute Outpatient Acquired Brain Injury Team developed a paper-based pacing and planning points system with a scale for rating the difficulty of daily activities (like grocery shopping, driving, and reading) according to the amount of energy each requires, and the severity of symptoms they trigger.

By tracking the maximum number of points they can comfortably expend in a day, patients learned how to self-manage their symptoms and improve participation in daily activities. In using this system, patients found they were able to reduce the severity and frequency with which symptoms occurred. A former outpatient said, "the points plan was such an effective way for me to get through the day without being utterly exhausted. I continue to use it as it has made me more independent, and as such, less reliant on my support people." In efforts to make this system more user-friendly and readily available for more patients, the investigators have created a mobile version of this planning and pacing points system, "MyBrainPacer™". Preliminary usability testing has indicated user and clinician satisfaction with the app.

For this next stage of development, the investigators plan to conduct a large-scale evaluation trial to demonstrate the effectiveness of the app more fulsomely. Completing this process will not only provide evidence related to the effectiveness of the app, but will also generate data to inform an existing gap in scientific literature: understanding of concussion recovery patterns. Analysis of the data will facilitate a better understanding of the patterns that exist between symptoms and everyday activity. In turn, this will enable development of a more personalized and customized version of the app, where the app 'learns' the patterns of a particular person and tailors their point system to their specific needs.
