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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  2. Patients whose muscle strength of the fistula limb is graded 4-5, which can overcome the 6-pound gravity and external resistance to complete the range of joint activity
  3. Patients who provided informed consent.

Exclusion Criteria:

  1. Left ventricular cardiac ejection fraction <30%;
  2. Using a arteriovenous graft or a long-term catheter as a permanent access;

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Changes in blood flow of AVF draining vein
Time Frame: from Baseline to 3 months
The blood flow measurement was repeated three times at a location 5 cm proximal to the anastomosis in the draining vein by Doppler ultrasound.
from Baseline to 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
