| Abstract: | Objective: Our aim was to develop and validate a user-friendly data logger system (SUDALS) for use with flexible electrogoniometry.Methods: Data pertaining to flexion/extension of the knee from 10 normal subjects were collected during a range of activities of daily living (ADL) such as walking, ascending and descending stairs, getting in and out of a chair and deep squatting. The accuracy, reliability and reproducibility of the data from SUDALS were verified by comparing against the data simultaneously collected from the Vicon system.Results: The results of these studies indicate that the SUDALS together with flexible electrogoniometers is able to produce stable, precise, accurate and repeatable knee flexion/extension angles with little variation existing between the data produced by the SUDALS, the Vicon system and that reported in the literature.Conclusion: The SUDALS together with flexible electrogoniometers is a useful clinical tool, capable of recording knee flexion/extension angles accurately during ADL. |
