Various methods that measures proprioception may induce abnormal sensory feedback which may result in inaccurate judgment of proprioception. Newer methods such as shadow goniometer, even though it is not inducing sensory feedback, still requires as a projector, current, protractor, darken room, and wide space. Smartphone applications are widely available, allowing Smartphone to be used as a protractor application for measuring ROM and Proprioception. However psychometric properties this app was not checked previously and it is not known that whether mobile app can be substitute for measuring proprioception. So there exists a need to find and reliability and validity of mobile application. If it is found reliable it can be used as tool for measuring proprioception. So, this mobile app it can be used for measuring joint ROM and proprioception of the joint. Ten healthy subjects were selected with an age group of 20-25. The standard goniometer was used to measure knee flexion followed by Mobile Application measurement of knee flexion. The measurements were repeated with Mobile Application on the second day. The mobile application was found to be a good reliable with interclass correlation of 0.897(p value <.001) and valid tool with correlation coefficient 0.950(p value <.003) in measuring knee flexion range of motion. The study concludes that the mobile application found to be a reliable and valid tool for measuring knee flexion range of motion and can be used to measure proprioception.
