  Telerehabilitation systems for stroke survivors have been predominantly
designed to measure and quantify movement in order to guide and encourage
rehabilitation regular exercises at home. We set out to study what aspect of
the movement data was essential, to better inform sensor design. We
investigated face-to-face stroke rehabilitation sessions through a series of
interviews and observations involving 16 stroke rehabilitation specialists
including physiatrists, physical therapists, and occupational therapists. We
found that specialists are not solely interested in movement data, and that
experiential information about stroke survivors' lived experience plays an
essential role in specialists interpreting movement data and creating a
rehabilitation plan. We argue for a reconceptualization in stroke
telerehabilitation that is more inclusive of non-movement data, and present
design implications to better account for experiential information in
telerehabilitation systems.
