In addition, comprehensive studies to be carried out in large cohorts, including patients, will provide Disclaimersįunding: This study was financially supported by a grant from the Akdeniz University Research Fund, grant number TSA-2020-5373.Ĭonflicts of interest: The authors, their immediate families, and any research foundation with which they are affiliated have not received any financial payments or other benefits from any commercial entity related to the subject of this article. Apart from the software we use in our study, we think it is important to test other software solutions created by the customer or purchased commercially in the market. In the analysis of kinematic data, besides the hardware, the software used is also critical. ConclusionĪzure Kinect can perform better position estimation, thanks to its superior hardware, than its previous generation predecessor could. Our study is the first on this subject to the best of our knowledge.Ĭontrary to depth sensors, marker-based systems cause a loss of time during marker placement, and markers negatively affect patient comfort. According to our findings, both sensors showed similar reliabilities in flexion and abduction movements, while Azure Kinect performed better in rotation. This study tested the concurrent reliability of basic upper limb movement using Kinect v2 and its successor Azure Kinect depth sensors. When the reliability of both sensors Discussion The intraobserver and interobserver reliability of the Azure sensor was from 0.64 to 0.91 and 0.60 to 0.97, respectively (Table I). The intraobserver and interobserver reliability of the Kinect sensor was from 0.47 to 0.84 and 0.64 to 0.96, respectively. We determined that the reproducibility varies depending on the movement performed. We tested the intraobserver and interobserver reliability of the measurements from both sensors in a test-retest situation. Analyses were performed by an experienced Results All participants were of Caucasian ethnic origin, and all had undergraduate or postgraduate education. The average age and body mass index (BMI) of the volunteers were 27.9 ± 4.8 years (range, 23-41) and 24 ± 4 (range, 19-32), respectively. Each volunteer's American Shoulder and Elbow Surgeons score was 100 points. This prospective study included a total of 20 healthy volunteers, ten males and ten females, without any shoulder pathology history.
