Background:
Different tools are used by occupational therapist to measure range of motion of a gesture. There are applications to measure range of motion with a smartphone in a few seconds. Usability involves ease in using a tool, so it is important to understand the usability of an application to ease the use of this application by occupational therapist and other health professionals.
Method:
Prospective study. The application was installed onto the smartphone of 10 occupational therapists and 10 physiotherapists to measure the range of motion of a gesture (Shoulder abduction 90 degrees).
Usability was measured by SUS (System Usability Scale). This scale was based on a 10 item questionnaire with 5 possible answers. The total punctuation was between 0 and 100.
Results:
We found an excellent usability for this application to measure range of motion, with a punctuation of 84,72 (±14,44). There are studies that have develop and application to measure range of motion (1,2) but these studies have not measure the usability.
Conclusion:
The application to measure range of motion by health professionals had an excellent usability, therefore this application is easy to use by these professionals and will be very useful to measure range of motion in a large number of pathology even to measure the performing of activities of daily live.
Application to Practice:
This application could be used by professionals of health science due to the excellent usability to measure range of motion with a smartphone in a few seconds.
