Augmented Reality Implementation on Physical Therapy Exercise

Physical therapy exercise (PTE) is a planned physical activity that is enabled to enhance body functions, reduce risk and improve the overall health of a person. In this research, range of motion (ROM) for shoulder PTE was investigated. There are three types of shoulder PTE involved: shoulder horizontal flexion and extension, shoulder external rotation and shoulder flexion and extension. To compare the conventional shoulder PTE with the shoulder PTE that is implemented with current technology, an augmented reality (AR) application is designed and implemented to those shoulder PTE. In this research, it is found that ROM of shoulder horizontal flexion and ROM of shoulder flexion were classified well between the group with AR and the group without AR. This is due to their classification accuracy is quite high in the KNN classifier (accuracy >80%). Lastly, the group with AR and group without AR for each ROM of shoulder PTE are compared using paired sample t-test. The result showed that all the ROM of shoulder PTE has a high significant difference (when p-value <0.05) between the group with AR and group without AR as the p-value is extremely small.
