Brief summary
Persons post stroke executed stepping activities under four conditions: standard of care, interacting with: an off-the-shelf Microsoft-Kinect game, with a self-paced repeated custom video game and a game-paced random custom video game. Exercise intensity (neuromuscular and cardiovascular), enjoyment and perceived effort were measured during and after each condition.
Detailed description
Persons post stroke were first familiarized with the four exercise conditions and then instrumented with a metabolic system and heart rate sensor. They played the games in two counter balanced blocks: repeated (standard of care and self-paced repeated custom) and random (Microsoft-Kinect game and game-paced random custom). Games were played for 8.5 minutes with ten minutes of rest in between so they could return to physiological baseline. During exercise they reported exertion and at the end of teach exercise trial they completed an enjoyment questionnaire. At the end of the first block, participants removed the metabolic system's mask and were assessed for motor recovery. Performances were video taped. At the end of data collection preferences for the activities were ranked and participants answered open ended questions. Data for neuromuscular and cardiovascular intensity, enjoyment and perceived effort were reduced and analyzed using a Repeated Measures Analysis of Variance (RMANOVA) with the appropriate post-hoc corrections. Where possible clinically meaningful changes were calculated.
Interventions
BEHAVIORALExercise
Participants performed stepping movements that were either cued by the investigator or interacted with a video game. There were three video game exercises that all involved stepping in either a repeated or a random pattern that was either self-paced or game paced.

Masking description
Participants were told that the purpose of the study was to learn more about what type of exercise they liked. There was no indication that intensity was an outcome measure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Borg Rate if Perceived Exertion Scale | Collected three times (at the beginning, middle and end) of each of the four exercise bouts during a single two hour session | Measures perception of effort on a scale of 6-20 |
| Cardiovascular intensity (metabolic Units) | collected continuously during each of the four conditions. Collected in a single 2 hour session | metabolic units measured continuously during each exercise bout |
| Cardiovascular intensity (Percent of maximum heart rate) | collected continuously during each of the four conditions. Collected in a single 2 hour session | the percent of the maximum heart rate |
| Enjoyment | four times collected in a single 2 hour session (once at the completion of each the four conditions). | measured with the PACES questionnaire after each exercise bout |
| Neuromuscular intensity | collected continuously during each of the four conditions. Collected in a single 2 hour session | movement repetitions (stepping and marching) measured through video tape measured continuously during each exercise bout |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Preference ranking | collected once at the end of the completed data collection of a 2 hour session | ranking exercise preference from highest (1) to lowest (4) |
| Fugl Meyer Motor Assessment Scale_ Lower Extremity Section | collected once during the single 2 hour data collection session | measure of lower extremity motor recovery |
Other
| Measure | Time frame | Description |
|---|---|---|
| Open ended questions | collected once during a single 2 hour data collection session | questions about preference and exertion and anything else the participants wants to share |
