Abstract
During the height of the COVID-19 pandemic, physical therapists worldwide turned to telerehabilitation to continue providing care for patients who need it. However, this posed a challenge in using standard assessment procedures which were difficult to implement online. Physical therapists could assess a patient’s balance in telerehabilitation, however there were limitations which impeded the validity and reliability of assessments. Thus, this study was conducted to determine the concurrent validity and test-retest reliability of the Phyphox smartphone accelerometer in measuring dynamic postural stability compared to the Modified Star Excursion Balance Test (mSEBT), which was an established tool for evaluating dynamic postural stability. The study utilized 8 healthy studentathletes from an HEI in Dasmariñas City, Cavite who were tasked to perform the mSEBT with the accelerometer attached to their lower lumbar spine. The study was conducted in a telerehabilitation setting, with the research assistant physically present during data collection while the researchers and research supervisor observed the data collection process through video conference call. Two variables were observed, namely the linear acceleration (m/s2 ) from the accelerometer and the reach distance (cm) from the mSEBT. The two sets of data were analyzed using the Pearson correlation coefficient and the Intraclass correlation coefficient. The study concluded that the accelerometer had a weak concurrent validity and poor test-retest reliability, indicating that the tool may yield inaccurate and inconsistent results when used for dynamic postural stability testing. Negative correlations were observed as there was inconsistent relationship between the accelerometer and mSEBT data. However, the current study was unable to obtain a sufficient sample size to represent the study population, thus there is a possibility of bias in the results obtained.
