Current goal

Create motivating games to Train on a set of rehabilitation dimensions (e.g. rhythm) Inspire therapists, patients, and others Explore the requirements and viability Get experience right

* so not yet a generalizable effect study

6

Approach

Use current excercises as a starting point Guided by the therapist Actions performed repetitively Actions steered to be performed one way Reflection on performance (e.g. rhythm)

7

IMPLEMENTATION: 8x1m floor, programmed game

8

IMPLEMENTATION: 4 games

9

IMPLEMENTATION: personalization (using a simple webform)

Results – study 1

All but one liked it more still for some too easy, others too hard

Perceived equal or more effort All therapists would want to use it

“You are forced to use your `wrong’ leg in the random mode, that is very good!”

“I do not know any other games where I can use this many relevant parameters”

“I never get him to run, he just does not want to. Now he is just running and he

enjoys it too!”

Results – study 1

Negative aspectes Looking down, specific muscles, cognitive challenges, small space

Suggestions More games (themes for kids) More flexible settings, e.g. adjust width of path Incorporating weight support: bar, crutches, harness

12

Results – study 2

Expressions of joy Play-again (33/37)

For 4 too easy, for some too hard Scores help to motivate

Inaccuracy in score is frustrating Dynamic aspects of Swiss Cheese, and cognitive Crazy Object

13

Results – study 2

Some therapist did not see new functionality Others saw increased enjoyment and motivation, adding to variety

Even more games, suggestions based on training dimensions

*not part of the study/paper but based on a workshop: Closer to Activities of Daily Living

14

Discussion

Informative feedback E.g. unbalanced, asymmetric, or arrhythmic Therapists’ feedback not replaced

* Thin line between gamification and keeping close to actual tasks

15

Summary

Games for changing behavior A suite of games, each with adjustable settings based on therapy Games trigger certain actions, based on traditional gait rehabilitation Difficulty still not tailored perfectly Here as well, games can be motivating Positive responses Dynamic and cognitive aspects can be of added value
