Isometric exercise can effectively promote the vascular function of arteriovenous fistula and increase hand grip strength, but patients needs to perform isometric exercises patiently. The purpose of this study want investigate the effect of using individual intelligent devices for forearm isometric exercise training on the increase of arteriovenous fistula vascular function and hand grip strength, and the improvement of patients' adherence with forearm isometric exercise.
