Abstract
I read the psychometric research by Dejaco et al. with great interest entitled “The concurrent validity and reliability of virtual reality to measure shoulder flexion and scaption range of motion” [1]. The authors focused on the clinometric analysis of virtual reality (VR)-based active range of motion measurement. As a result of the study, although VR-based shoulder active range of motion measurement was found to be valid and reliable, the wide confidence intervals were noted in the analysis reflecting the degree of error. The authors stated that care should be taken to ensure that VR does not replace other reliable tools in measurement. Although I consider that the authors have made an essential contribution to the physiotherapy and rehabilitation literature with this study, some methodological issues should be discussed further.
