Purpose: The COVID-19 pandemic has changed how healthcare is delivered worldwide and has affected the environment of the healthcare. Physical therapy in traditional healthcare systems can be difficult in unusual circumstances, such as the COVID-19 pandemic. Tele-physical therapy, defined as "the delivery of the physical therapy at a distance using electronic information and telecommunication technologies," will be a solution for this healthcare crisis. Thus, in this study, we proposed a mobile application for tele-physical therapy. Methods: This study used the Chrome Browser version 83.0.4 based on the Windows 10 64Bit operating system to use the App Inventor. To operate the mobile application, we used the Samsung Galaxy Note 9. The design of the mobile application was based on the review of a system used in the physical therapy department. Results: The graphical user interface (GUI) of the mobile application was displayed on three screens: selecting a painful joint (1st screen of the GUI); selecting a painful movement of the joint (2nd screen of the GUI); a self-manual therapy method and movie (3rd screen of the GUI). The proposed mobile application showed the stable repeatability of the self-manual therapy movie. Conclusion: The results of this study demonstrated that the proposed mobile application using the App Inventor for android will be able to create easy to use and reliable tele-physical therapy.

Background: This study was performed to identify what effect plyometric exercise with application of kinesio taping gives on muscle activity and power of lower limb. Methods: In order to conduct research, total 14 male students at G university located Gwangyang city were randomly assigned; 7 for experimental group (with kinesio taping application) and 7 for control groups(without kinesio taping application) were conducted with box drill, one of the plyometric exercise 5 times a week for 4 weeks. Muscle activities were measured by using electrodiagnosis equipment on quadriceps and gastrocnemius. Collected data was analyzed by using Windows SPSS version 19.0. Results: Muscle activities show statistically significant differences (p<.05) both before and after exercise in experimental and control groups in terms of vastus medialis, rectus femoris, vastus lateralis and lateral gastrocnemius. However, only medial gastrocnemius shows statistically significant differences in experimental group compared before and after exercise. Sargent jump for measuring power shows that only experimental group presents statistically significant differences (p<.05). Two groups show that vastus medialis, vastus lateralis, lateral gastrocnemius and medial gastrocnemius only in muscle activities show statistically significant differences (p<.05) after exercise. Conclusion: The result of this survey indicates that plyometric exercise is effective to improve muscle activity and power of lower limb, especially, the group who exercises with application of kinesio tape is more effective than the other group with no tape application. Therefore, it is considered that plyometric exercise with tape is more effective to improve power and muscle strength.
