Summary
This study introduces novel games to assess arm mobility, focusing on range of motion and control. These assessments provide valuable metrics for characterizing arm function and tracking improvements during rehabilitation.
Area of Science:
- Biomechanics
- Rehabilitation Medicine
- Human Motor Control
Background:
- Arm mobility in planar reach movements is often assessed using planar position and vertical force measures.
- A comprehensive evaluation of mobility performance requires assessing four key capacities: range of motion, range of force, control of motion, and control of force.
Purpose of the Study:
- To present a novel set of games designed for the assessment of arm mobility.
- To demonstrate the utility of these games in characterizing patient performance and tracking rehabilitation progress.
Main Methods:
- Development of interactive games for assessing four capacities of arm mobility.
- Utilizing the ArmAssist device for a 2-week clinical pilot study.
- Recording motion profiles and computing key metrics for range of motion and control of motion assessments.
Main Results:
- Initial plots of motion profiles and computed metrics are presented for a single patient.
- Assessment plots illustrate performance across four of seven training sessions.
- Metrics computed across all seven sessions demonstrate patient progression over the study period.
Conclusions:
- The developed games provide a viable method for assessing arm mobility and its constituent capacities.
- The computed metrics effectively capture performance and progression in a clinical rehabilitation setting.
- This approach offers a promising tool for detailed impairment assessment and monitoring of arm function recovery.
