About

Isometric exercise can effectively promote the vascular function of arteriovenous fistula and increase hand grip strength, but patients needs to perform isometric exercises patiently. The purpose of this study want investigate the effect of using individual intelligent devices for forearm isometric exercise training on the increase of arteriovenous fistula vascular function and hand grip strength, and the improvement of patients' adherence with forearm isometric exercise.

Full description

An arteriovenous fistula(AVF) is the most preferred and safe vascular access for long-term hemodialysis patients. Isometric exercise can effectively promote the vascular function of AVF and increase hand grip strength, but patients needs to perform isometric exercises patiently. However, the patient's disease factors, muscle soreness caused by the exercise process, etc., may easily prevent the patient from effectively performing isometric exercise every day.This study will be the first isometric exercise training intervention program for eight weeks after AVF surgery with an intelligent device in Taiwan. Investigators expect to promote the vascular function of AVF and increase hand grip strength, as well as improve participant' adherence performance after the re-intervention protocol. To construct an intelligent forearm isometric exercise, as a reference for clinical care guidance.

54 participants in 2 patient groups

Experimental group

Experimental group

Description:

Participants performed wrist-forearm exercise training within 2 weeks after the operation, that is, from 24 hours to 2 weeks after the operation, twice a day in the morning and evening, 3 groups each time, and each single item was repeated 5 times in each group (maintain for 5 seconds). Exercise for 40 minutes a day, use the mobile phone to install the forearm isometric exercise software program within the 3rd to 8th week, use the Bluetooth device to connect the hand-held gripper to perform the forearm isometric exercise, 2 times a day, morning and evening, and train 3 groups each time, 20 times each time , hand grip strength for 3 seconds each time, increase by 1 second per week, and rest for 90 seconds between groups.

Treatment:

Behavioral: Forearm isometric exercise intervention program

Control group

Other group

Description:

The control group began to use soft rubber balls for isometric contraction exercise from the 2nd day to the 8th week after operation. 2 times a day in the morning and evening, 3 groups of training each time, each group holds the ball for 5 minutes, and rests for 90 seconds between groups. Each grip training must be completed 20 times within 1 minute (keep 3 seconds each time in the first week) , increase by 2 seconds every week, and keep each grasping time for 10 seconds from the 5th to the 8th week.

Treatment:

Behavioral: Forearm isometric exercise intervention program
