**4. Conclusions**

Summary of this study report

**1.** We examined H-reflex and F-wave data resulting from increased stimulus intensity in the affected arm in patients with CVD. The results suggested that the characteristic appear‐ ance of the H-reflex and F-wave resulting from increased stimulus intensity reflects the neurological findings of CVD and can be used to evaluate excitability of spinal neural function in patients with CVD.
