About this study
Official title: Effect of Dumbbell Exercise on Arteriovenous Fistula in Patients With Hemodialysis：A Prospective Randomized,Controlled Trial
Isometric exercise has been shown to increase the diameter and the blood flow rate of forearm veins.At present, more studies focus on the perioperative period to promote the maturation of arteriovenous fistula(AVF), while there are few reports on functional maintenance measures for the patients with maintenance hemodialysis.This study aims to explore the effect of dumbbell exercise on AVF，and evaluate whether patients can carry a 6-pound item with the fistula limb in a reasonable way.
Read the detailed description
Autologous arteriovenous fistula (AVF) is the preferred vascular access for maintenance hemodialysis patients. It is estimated that AVF accounts for 85-90% of the permanent vascular access in Chinese hemodialysis patients. With the prolongation of dialysis time, aging, and the increase of diabetes incidence, the complications of AVF are more and more common, which affect the lifetime of AVF. Therefore,self-maintenance of AVF is essential. Among them, exercise should be used throughout the entire process of AVF use for the reason that it is economical, easy to operate, and highly repeatable.The most common isometric exercise is handgrip exercise. However, there are some deficiencies in this exercise, such as lack of quantitative standards and burnout of repeated actions. As a result, this study uses quantitative dumbbells as a training tool to explore the effect of dumbbell exercise on the maintenance of AVF, and further evaluates and breaks the nursing routine of "no lifting weights" of fistula limb.

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03741985, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
