Patent number: 11596328Abstract: This disclosure relates generally to health monitoring and assessment systems, and more particularly to perform postural stability assessment of a user and quantify the assessed postural stability. In an embodiment, the system, by monitoring specific actions (which are part of certain tests done for the postural stability assessment) being performed by a user, collects inputs which are then processed to determine SLS duration, the body joint vibration, and the body sway area of the user, while performing the tests. By processing the SLS duration, the body joint vibration, and the body sway area together, a postural stability index score for the user is determined, and based on this score, postural stability assessment for the user is performed.Type: GrantFiled: March 7, 2018Date of Patent: March 7, 2023Assignee: Tata Consultancy Services LimitedInventors: Oishee Mazumder, Kingshuk Chakravarty, Debatri Chatterjee, Aniruddha Sinha, Abhijit Das
