Occupational wrist postural assessment and monitoring system: development and initial validation

| Summary: | Identification and quantification of poor wrist postures at the occupational setting
are generally challenging due to rapid changes in wrist movement. A system
prototype was developed to capture and assess wrist postural behaviour at the
workplace. This manuscript describes the development and initial validation
process of the system prototype. The system prototype utilizes wearable glove
attached with Inertia Measurement Unit (IMU) sensors to capture wrist postural
behaviours. The postural angle data from sensors were extracted and processed
through a customized programming software for visualization purpose. The realtime wrist postural angle data at work is benchmarked and normalized to personal
maximum wrist Range of Motion (ROM) data. Preliminary validation compared
the wrist postural angle readings between system prototype and traditional
goniometer, at 30 for ulnar, radial, flexion, and extension wrist positions.
Overall, the results from one sample t-test across 31 subjects indicate statistically
no significant differences between the system prototype and goniometer readings
at alpha level 0.05 (p-value > 0.05). The results from this preliminary validation
activity demonstrate a degree of accuracy in terms of capturing wrist postural
angle when being compared to goniometer. |
