Summary
Digitizing postural control tests with the Matti device shows feasibility for children. While not fully concurrent with traditional methods, digital testing enhances enjoyment and offers potential for pediatric assessment.
Area of Science:
- Pediatrics
- Biomedical Engineering
- Rehabilitation Science
Background:
- Postural control deficits are prevalent in children, impacting function.
- Performance-based tests offer insights but are underutilized clinically.
- Digitizing these tests can improve implementation and data collection.
Purpose of the Study:
- To assess the feasibility and validity of the 'Matti' pressure-sensitive device for digitizing postural control tests.
- To evaluate the Matti device's performance in recording data for the One-Board Balance Test (OBBT) and Lateral Jump Test (LJT).
- To compare digital test outcomes with conventional methods and assess children's enjoyment.
Main Methods:
- A cross-sectional study involving 46 typically developing children.
- Conventional and digitized versions of the OBBT and LJT were administered.
- Concurrent validity and agreement were assessed using correlation analyses and Bland-Altman plots.
- Participant enjoyment was measured using a Smiley-o-Meter.
Main Results:
- Digitized testing demonstrated strong correlations between digital and observer scores for both OBBT (rs=.991) and LJT (r=.962).
- Significant differences were observed between conventional and digitized test conditions.
- Children reported significantly higher enjoyment during digital testing (p = 0.011).
Conclusions:
- The Matti device is feasible for simple, digitized performance-based postural control testing in children.
- Lack of concurrent validity with conventional tests necessitates further research.
- Digital testing's higher perceived enjoyment suggests potential for pediatric assessment and rehabilitation.
