Abstract

The study was a quantitative type of research. The population of the study was 49 students of DLSMHSI-CRS-PT batch 2021. The sampling method used was convenience sampling. A total of 14 participants chosen via convenience sampling wherein two respondents dropped out due to a conflict in scheduling. The 12 respondent were asked to walk at least 100 steps for one minute on a treadmill going 5 km/hr while having the KAC application strapped around the waist at the S2 level in accordance with the modified Walk Protocol using a treadmill. The respondents were asked to do two trials of the procedure for test-retest reliability and results were compared with manual counting of the steps for construct validity. The KAC application was used to teach the cadence of the participants. As for the results the construct validity of the KAC showed "low positive correlation" for phone model GL30FD and showed a "very high positive correlation" for phone model A720F in measuring cadence of apparently healthy individuals. The ICC generated for test-retest reliability of phone model GL30FD shows "poor reliability" and for phone model A720F shows "moderate reliability" in measuring cadence of apparently healthy individuals. This study showed that the KAC application is not a valid and unrealiable tool in measuring cadence of apparently healthy individuals.
