Objective To determine usability – perceived rating of usefulness, ease of learning, ease of use, effectiveness, satisfaction, and interface quality – and effect of a mobile health (mHealth) program delivering active rehabilitation for concussion.

Design Case series.

Setting Multi-center.

Participants Patients diagnosed with a concussion.

Interventions (or Assessment of Risk Factors) A mHealth delivered active rehabilitation program was provided to users for two weeks.

Outcome Measures mHealth app usability questionnaire (MUAQ) and concussion symptoms.

Main Results Thirty-one total participants took place in a two-week mHealth program (female, n = 24; male, n = 7). The average age of participants was 33.5 years old. Symptom severity scores decreased by a mean of 12 points in participants (interquartile range [IQR] of the difference = -1.7 – 26) over the two-week program. Of the 31 participants, 23 (74%) responded to the mHealth app usability survey upon completion of the program. On a 4-point Likert scale ranging from somewhat disagree to strongly agree, and a positive response considered either ‘agree’ or ‘strongly’ agreed, 86% of participants were overall satisfied with the app (91% were either ‘satisfied’ or ‘very satisfied’), 87% found it useful for their well-being, 87% found it easy to use, and 91% would use the app again.

Conclusions A mHealth delivered active rehabilitation program decreased symptom burden in users. Users were overwhelmingly satisfied with the mHealth program, found it easy to use, would recommend it, and would use it again.
