Meanwhile, instrumental posturography has been used widely to obtain quantitative data and characterize balance abilities and underlying control mechanisms, but not as often for sitting balance. Moreover, traditional kinetic methods using a force platform to test sitting stability often require modification and are costly. We proposed a tracker-based posturography with a commercial virtual reality system, the VIVE Pro system (HTC, Inc. Taiwan), to record the trunk displacement (TD) path with a lumbar tracker for evaluation of sitting stability. The goals were to test the reliability and validity of the TD parameters among stroke patients.enPostural stability; Sitting; Stroke; Virtual realityjournal article10.1186/s12984-022-01052-0358318352-s2.0-85133983754WOS:000824617800001https://api.elsevier.com/content/abstract/scopus_id/85133983754
