Sit2Stand: Software to compute sit-to-stand biomechanics using a mobile phone
Sit2Stand is an open-source web based tool that guides participants through the process of recording and uploading 5 time sit-to-stand (5STS) videos, and then automatically analyzes joint positions with detected 5STS cycles, and calculates timing and kinematic parameters. The platform includes a video to instruct participants on how to perform the test. Researchers can also add participant questionnaires through the online platform. The paper was published on in npj digital medicine in March 2023. All data generated in this study and the custom scripts for data processing, data analysis, and the web application are freely available on GitHub.
