To explore the influence of exercise therapy on dialysis adequacy and psychological status quality of life in maintenance hemodialysis(MHD)patients.

A total of 100 patients who underwent MHD from November 2016 to June 2019 in our dialysis center were selected as the research subjects and randomly assigned to the experimental group and the control group. The experimental group were treated with 30-minute treadmill training three times a week within 2 hours of the start of dialysis on the basis of conventional dialysis. The patients in the control group were not given exercise intervention on the basis of conventional dialysis. After 24 weeks, the dialysis adequacy, self-rating anxiety scale (SAS), self-rating depression scale (SDS) and mortality were compared between the two groups using statistical method. P<0.05 was considered to be statistically significant.

A total of 96 patients completed the trial, including 58 males and 38 females, aged from 27 to 75 years old, with the average age of (57±14). There were 49 cases in the experimental group and 47 cases in the control group. In terms of dialysis adequacy, there was no significant difference in Kt/V and URR between the two groups before treatment (P>0.05), nor was the change value of Kt/V and URR after 24 weeks significantly different from that in the control group (P>0.05). In terms of psychological state, the decreases of SAS and SDS scores after 24 weeks were significantly higher than those in the control group (P<0.05). As for mortality, the mortality rate in the experimental group was lower than that in the control group (10% vs.19%), but there was no significant difference between the two groups (P=0.21).

Exercise during dialysis can effectively improve the psychological status and quality of life of hemodialysis patients. The impact on survival needs to be confirmed by further studies.
