Self-Directed Upper Extremity Gaming in Inpatients With Stroke

Taken by study staff during session. Notes are entered into structured template.

Study staff record days of attempted use and reasons for missed days, when available.

10-item assessment, each item rated on a 5-point Likert scale. Items are scored to yield a total score from 0 to 100, with higher scores indicating better perceived usability.

Participants are asked to rate their satisfaction for STRIVE on a 5 point scale that ranges from "not satisfied" at all to "very satisfied." Quest has 12 items, with higher scores reflecting higher user satisfaction.

STRIVE will automatically record data that includes session start/end time, duration, active play time, number of sessions completed, and performance metrics.

STRIVE will automatically record data that includes session start/end time. Duration will be calculated via END_TIME-START_TIME.

Adverse events (recorded as note to files), safety events (recorded as note to files), staff support time required (recorded total minutes per staff per participant)

Descriptive assessment of interest/enjoyment and perceived competence. 8-14 items. Items are rated on a likert scale of 1-7, where the higher the score, with a 7 indicating the participant strongly agrees the item statement.

Rated via observation of participant engaging in STRIVE during a typical session by a member of the study team. 6- point Likert-type scale, with a 0 indicating no participation, and 6 indicating excellent participation.

Feasibility of the STRIVE intervention, measured as the number of STRIVE sessions each participant completed over the intervention period. A session is considered completed if the participant engaged with the STRIVE system for at least 30 minutes per day and the session is logged by the system. Sessions that were started but did not meet this threshold, and sessions missed for any reason, are counted as not completed. Each participant is assigned a single count, and the number of completed sessions is reported as a mean across participants. Higher values indicate greater intervention uptake.

Acceptability of STRIVE rated by participants on a custom 10-item questionnaire administered verbally or on paper. Each item is scored on a 5-point Likert scale from 1 to 5, and item scores are averaged to yield a single mean score ranging from 1 to 5. Higher scores indicate greater acceptability. This is a non-validated instrument developed for this study.

Participants complete a semi-structured qualitative interview with open-ended prompts addressing acceptability, perceived benefit, barriers to independent use, and suggestions for improvement. Responses are transcribed and coded. The reported value is the count of distinct usability issues identified across participants, where an issue is defined as a discrete, non-redundant barrier to independent system use.

Movement smoothness of the more affected upper limb during STRIVE gameplay, quantified as log dimensionless jerk from motion data from the STRIVE system. Values are computed per reaching repetition and averaged across all repetitions within a session. Lower (more negative) values indicate smoother movement. This measure is reported in unitless log dimensionless jerk.
