Nirawitt Suansomchit, Supachai Vorapojpisut, Sairag Saadprai, Rodrigo Rodrigues Gomes Costa, Rodrigo Rodrigues Gomes Costa, Rodrigo Rodrigues Gomes Costa
TL;DR
MASSWU is a reliable and valid sensor system for measuring wheelchair performance during fitness tests, offering a simpler alternative to complex motion analysis software.
Contribution
MASSWU is introduced as a simpler, valid, and reliable system for wheelchair movement analysis compared to traditional 2D motion analysis tools.
Findings
MASSWU showed good to very good validity compared to Kinovea (r = 0.887–0.998).
Intra-rater reliability ranged from good to very good (ICC = 0.765–0.988).
Inter-rater reliability was also good to very good (ICC = 0.899–0.996).
Abstract
The Motion Analysis Sensor System for Wheelchair Users (MASSWU) is designed to collect wheelchair movement data such as distance, duration, speed, and angular velocity during competitions and training sessions to enhance athlete performance. Developed as a simpler alternative to complex 2D motion analysis software, MASSWU was evaluated for validity, intra-rater and inter-rater reliability by comparison with the established 2D motion analysis program Kinovea. The assessment involved six wheelchair skill-related fitness tests performed under simulated real-world conditions by twenty-three healthy wheelchair users aged 18–35. The tests included One Stroke Push (distance), Muscle Power Sprint (speed), 10x5-meter Sprint (duration), Slalom (duration), and 360° Clockwise and 360° Anticlockwise Rotations (angular velocity). Validity was evaluated using the Pearson Correlation Coefficient, while…
