Abstract

The study utilized an agreement type of research method. Using convenience sampling method, a total of 50 students randomly selected from all the sections of the senior high school program were estimated by the researchers to comprise the population that was assessed by the one registered physical therapist. The students performed Adam's forward bending with results being measured using a smartphone application Scoliometer installed on a Samsung Galaxy S5, running on an Android operating system utilizing the Lollipop software, verskion 5.0 and the traditional inclinometer. The research design used anintraclass correlation coefficient (ICC) to determine the concurrent validity and intra-rater reliability. For the totality of the results for concurrent validity, the ICC was calculated at 0.064. This can be interpreted that the smartphone application Scoliometer has poor concurrent validity when compared with the traditional inclinometer since ICC is less than 0.4. A Bland-altman plot was used to provide a visual presentation of the degree of agreement between clinical measurements using smartphone application Scoliometer and traditional inclinometer which illustrated a mean difference of 0.380 and limits of agreement of the reference range for difference of -2.327 to 3.087. The intra-rater reliability average ICC measurement was 0.898 for comparison of the measurements by the assessor. This can be interpreted that the smartphone application has excellent intra-rater reliability.
