The Effects of Different Vibration Exercises on COPD Patients

January 14, 2025 updated by: Taipei Medical University

The Effects of Different Vibration Exercises on the Strength of Lower Extremity Muscles, Exercise Endurance, and Quality of Life Among COPD Patients

Pulmonary rehabilitation is effective in improving exercise tolerance, dyspnea, and fatigue in patients with COPD, and exercise training is an important component of pulmonary rehabilitation. Vibration training can be used as a supplement or alternative to traditional exercise and is a short, safe rehabilitation training.

COPD patients will be recruited and randomly assigned to the control group, whole-body vibration training group, or local vibration training group. The study aims to confirm the rehabilitative benefits of enhancing lower limb muscle strength, exercise endurance, and the quality of life related to COPD in patients.

Detailed Description

Background Pulmonary rehabilitation is effective in improving exercise tolerance, dyspnea, and fatigue in patients with COPD, and exercise training is an important component of pulmonary rehabilitation. Vibration training can be used as a supplement or alternative to traditional exercise and is a short, safe rehabilitation training.

Purpose To enhance the effectiveness of pulmonary rehabilitation, the vibration rehabilitation system will be applied on COPD patients to validate the effectiveness of direct and indirect vibration interventions on lower extremity muscle strength and functional performance in COPD patients, and test the effectiveness of vibration in improving lower extremity muscle strength, exercise tolerance, and COPD- related quality of life in COPD patients.

Methods COPD patients will be recruited and randomly assigned to the control group, whole-body vibration training group, or local vibration training group. The study aims to confirm the rehabilitative benefits of enhancing lower limb muscle strength, exercise endurance, and the quality of life related to COPD in patients.

Expected outcome To establish an optimal model for lower extremity vibration and to validate the effectiveness of direct vibration on the lower extremities and whole body vibration in COPD patients undergoing pulmonary rehabilitation.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Whole-body Vibration Training Group
Receive whole-body vibration twice a week for 12 weeks.
Device: Whole-body Vibration Therapy
Each session includes six series, each lasting 2 minutes, with a frequency of 35 Hz and an amplitude of 2 mm, with a 60-second rest interval between series. For the starting position, the patient stands relaxed on the platform, holding the WBV platform handles.
Experimental: Local Vibration Training Group
Receive local vibration twice a week for 12 weeks.
Device: Local Vibration Therapy
Each session includes six series, each lasting 2 minutes, with a frequency of 35 Hz and an amplitude of 2 mm, with a 60-second rest interval between series. After the warm-up exercise, the researcher helps the patient wear the localized vibration instrument. During the vibration, participants will hold onto the handle to ensure balance stability.
No Intervention: Control Group
Receive no intervention

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
6 Minute Walking Test
Time Frame: Base line, Week12, Week16
This test measures how far the patient can walk in 6 minutes, with a greater distance indicating better performance.
Base line, Week12, Week16
Maximal voluntary contraction force
Time Frame: Base line, Week12, Week16
The readings from the digital dynamometer can be converted into kilograms, with higher values indicating greater muscle strength.
Base line, Week12, Week16

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Five Times Sit to Stand Test (FTSST)
Time Frame: Base line, Week12, Week16
Score is the amount of time it takes for an patient to transfer from a seated position to standing position and back to sitting five times. A shorter time indicates better performance.
Base line, Week12, Week16
Clinical COPD Questionnaire score, CCQ
Time Frame: Base line, Week12, Week16

The scale ranges from 0 to 6, where higher scores reflect more severe conditions.

Score Range:

0: No impact or impairment. 6: Severe impact or impairment.
Base line, Week12, Week16
COPD assessment Test, CAT
Time Frame: Base line, Week12, Week16
CAT has a scoring range of zero to 40; higher scores indicate a greater severity of COPD's impact on a patient's life.
Base line, Week12, Week16
mMRC dyspnea scale, mMRC
Time Frame: Base line, Week12, Week16
The scale ranges from 0 to 4, with higher scores representing more severe conditions.
Base line, Week12, Week16
