• Aim– Investigate the performance characteristics associated with a

“treadmill-motion platform” configuration (Computer Aided Rehabilitation Environment [CAREN]-Extended system) and how system operation can affect the data collected.

• Relevance

– The CAREN allows researchers to address a number of research questions by enabling manipulation of the standing or walking surface and visual scene and by providing real-time biofeedback or enabling interaction with the virtual environment.

Method• Evaluated platform static and dynamic characteristics by

translating or rotating platform over progressively larger distances and comparing input and measured values.

• Assessed treadmill belt speed with and without person walking on platform and at different orientations.

• Examined force plate measurements to observe baseline drift:– When treadmill was in operation.– During ambulation.– Over time.

Results• Platform acceleration depended on distance

travelled and system settings.• Treadmill speed variability was greatest at faster

speeds.• Force plate measurements were affected by:– Platform and treadmill operation.– Contralateral impact forces during gait.– Baseline drift.

Conclusion

• Knowledge of performance characteristics and their effect on outcome data is crucial for effective design of CAREN research protocols and rehabilitation scenarios.
