Reviewer 2 Report

This paper shows the stiffness analysis of CDRP in upper limb rehabilitation applications. The main issues are as follows:

1. Lack of innovation. Most equations ((1)-(25)) have been presented by other publications. The authors should carefully cite their work.
2. The authors are suggested to highlight their contributions in the introduction.
3. Line 203: where is "G" in the equation(s)?
4. In Fig. 8, please change the position of the legend.
5. Other suggestions: the authors are suggested introducing disturbances, etc. to improve their theoretical work and conduct experimental validations.
