Objective To investigate the effect of stepped grip strength exercise on patients with forearm hypervascularity of stage 4 chronic kidney disease(CKD).Methods A total of 54 patients diagnosed with stage 4 CKD at 908th Hospital of Joint Logistic Support Force,Chinese People's Liberation Army from February 2018 to December 2021 were selected for the randomized controlled trial,and were divided into a control group and an experimental group by the random number table method,with 27 cases in each group.There were 17 males and 10 females in the control group;they were 32 to 74(49.67±13.03)years old;their disease course was 5-21(10.26±4.19)years.There were 15 males and 12 females in the experimental group;the were 28-71(50.31±14.43)years old;their disease course was 6-23(10.35±3.80)years.The control group did exercise with electronic grip apparatus,and the experimental group did stepped grip strength exercise with intelligent grip balls.The vascular diameters and blood flow velocities before exercise and 4 and 8 weeks after exercise and compliance were compared between the two groups.t and x2 tests used.Results After 8 weeks'exercise,the internal diameter of cephalic vein in the control group was lower than that in the experimental group[(1.98±0.15)mm vs.(2.12±0.21)mm],with a statistical difference(t=4.63;P＜0.05).After 4 and 8 weeks'exercise,the radial artery blood flow velocities in the control group were lower than those in the experimental group[(19.32±0.59)cm/s vs.(19.85±0.43)cm/s and(21.07±0.49)cm/s vs.(23.38±0.53)cm/s],with statistical differences(t=3.77 and 16.63;both P＜0.05).After 8 weeks'exercise,the compliance in the experimental group was higher than that in the control group[85.19％(23/27)vs.51.85％(14/27)],with a statistical difference(x2=6.95;P＜0.05).Conclusion Stepped grip strength exercise for patients with forearm hypervascularity of stage 4 CKD can dilate their inner diameter of the cephalic vein,accelerate the radial artery blood flow,and improve their vascular conditions,with high exercise compliance.
