Effect of Exercise on Fatigue in Patients Receiving Maintenance Hemodialysis Treatment: A Systematic Review and Network Meta-analysis.

Abstract

This study aimed to evaluate the effect of different exercises for improving fatigue in maintenance hemodialysis patients. PubMed, Embase, Web of Science, Cochrane, PEDro, CNKI, VIP, Wanfang data, CBM, and CINAHL were conducted from the establishment of the database to July 2023. We independently screened the literature, evaluated the quality, analyzed the data using Stata 15.0, and performed subgroup analysis on intervention time and exercise intervention adherence. Twenty-three studies were analyzed, with 1867 patients and nine interventions. Based on the surface under cumulative ranking curves and pairwise comparisons effects, overall long-term, short-term, and exercise intervention adherence >90% effects have all presented that during dialysis aerobic-resistance combined exercise was ranked as the most effective compared with routine care (surface under cumulative ranking curves = 83.9%, standardized mean difference = -1.45, 95% CI = -2.23 to -0.67; surface under cumulative ranking curves = 85.9%, standardized mean difference = -1.38, 95% CI = -2.24 to -0.52; surface under cumulative ranking curves = 86.6%, standardized mean difference = -1.54, 95% CI = -2.58 to -0.49; surface under cumulative ranking curves = 83.6%, standardized mean difference = -1.45, 95% CI = -2.25 to -0.66, respectively), followed by interdialytic period muscle relaxation exercise, interdialytic period aerobic-resistance combined exercise, interdialytic period aerobic exercise, and interdialytic period Baduanjin. Dialysis aerobic-resistance combined exercise may be considered in practice when resources allow. However, high-quality, multicenter, and large-sample randomized control trials must further verify this conclusion.
