Abstract:
Vibratory
stimulation may improve post-stroke symptoms such as spasticity;
however, current studies are limited by the large, clinic-based
apparatus used to apply this stimulation. A wearable device could
provide vibratory stimulation in a mobile form, enabling further study
of this technique. An initial device, the vibrotactile stimulation (VTS)
Glove, was deployed in an eight-week clinical study in which sixteen
individuals with stroke used the device for several hours daily.
Participants reported wearing the glove during activities such as
church, social events, and dining out. However, 69% of participants
struggled to extend or insert their fingers to don the device(Duh! Spastic fingers are impossible to get into gloves. You didn't do your planning properly by talking to actual survivors with spasticity.). In a
follow-up study, eight individuals with stroke evaluated new VTS device
prototypes in a three-round iterative design study with the aims of
creating the next generation of VTS devices and understanding features
that influence interaction with a wearable device by individuals with
impaired upper-limb function. Interviews and interaction tasks were used
to define actionable design revisions between each round of evaluation.
Our analysis identified six new themes from participants regarding
device designs: hand supination is challenging, separate finger
attachments inhibit fit and use, fingers may be flexed or open, fabric
coverage impacts comfort, a reduced concern for social comfort, and the
affected hand is infrequently used. Straps that wrap around the arm and
fixtures on the anterior arm were other challenging features. We discuss
potential accommodations for these challenges, as well as social
comfort. New VTS device designs are presented and were donned in an
average time of 48 seconds.
