AI Article Synopsis
- A study was conducted to assess the reliability of using a triaxial accelerometer to measure head movement while occupational typists were typing.
- Results showed high intra-rater reliability, indicated by an intraclass correlation coefficient of 0.986, suggesting the accelerometer provides consistent measurements.
- The study concludes that the triaxial accelerometer is an effective and straightforward tool for objectively measuring head excursion in typists.
Article Abstract
Background: The reliability of a triaxial accelerometer in measuring the head excursion during typing task among occupational typists has not been reported so far.
Objective: This study aimed to investigate the intra-rater reliability of triaxial accelerometer measurement of head excursion.
Methods: The triaxial accelerometer measurements were taken to measure head excursion of 8 participants typing in the computer. The intra-rater reliability such as intraclass correlation coefficient, standard error of measurements and coefficient of variation was calculated. The Bland-Altman plot was performed to strengthen the study result.
Results: The analysis of the results showed that the intra-rater reliability of triaxial accelerometer was high with intraclass correlation coefficient (2,1) of 0.986, standard error of measurements (1.05 Hz) and coefficient of variation (3.2%) for two trials of measurements. The Bland-Altman reported an acceptable agreement between the two measurements taken using the triaxial accelerometer to measure head excursion.
Conclusions: The triaxial accelerometer is a simple, objective and useful technology to measure head excursion among the occupational typists.
