  1. This table displays the results of the responses to survey questions regarding the usability of the two activity questionnaires employed for patient self-triage of functional capacity, the Duke Activity Status Index (DASI), and the Patient-Reported Outcomes Measurement System (PROMIS)–Short Form 12a–Physical Function. The majority of study participants found these questionnaires easy to understand and easy to complete using a first generation iPad. The average time to complete both surveys was less than 3 min
