ClinicalTrials.gov Identifier:
NCT00735618
First Posted: August 15, 2008

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
M.D. Anderson Cancer Center
  Purpose

Primary:

  • To characterize the physiologic changes of the autonomic nervous system, demonstrated by heart rate variability (HRV) high frequency (HF) spectral analysis, before and after a 15 minute, one-time, guided relaxation program for cancer patients.

Secondary:

  • To assess whether change of HRV correlates with subjective feeling for anxiety, based on visual analog scale scores.

Condition Intervention
Cancer Other: Guided Relaxation

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Pilot Study on the Effects of a Brief Relaxation Program on Heart Rate Variability in Cancer Patients

Further study details as provided by M.D. Anderson Cancer Center:

Primary Outcome Measures:
  • Differences Between Pre/Post ESAS Score [ Time Frame: Baseline and following completion of HRV recordings and relaxation program (45 - 60 minutes elapsed time) ]
    Total symptom burden as measured by Edmonton Symptom Assessment Scale (ESAS) in which there are eight visual analog scales (VAS) of 0 to 10, with 10 being most severe. The differences from ESAS baseline (before) to post (after) a 15 minute, one-time, guided relaxation program for each participant assessed, with the average difference in ESAS scores for all participants reported.

  • Relaxation Therapy
  • Guided Relaxation Program

Detailed Description:

Rhythm changes in your heart rate are part of the "autonomic" nervous system. This is the part of your nervous system that controls the body functions that you do not have to think about. Researchers want to find out if a "guided relaxation" session will make your heart rate more variable, with more rhythm changes.

If you are found to be eligible to take part in this study, you will first answer a brief questionnaire that will measure several symptoms, such as pain and anxiety (worry). This questionnaire will take less than 5 minutes. You will also be asked questions about your alcohol and smoking history, and if you have ever used relaxation or meditation techniques in the past. This will also take less than 5 minutes.

You will then be asked to lay on your back, on a hospital bed or exam table. Electrodes will be placed along your chest, the same way they are placed for an electrocardiogram (ECG--a test to measure the electrical activity of the heart). You will be asked to rest for 15 minutes, and then your heart rhythm will be recorded for 5 minutes. After this first recording, you will begin the relaxation program by listening to an audio recording for about 15 minutes, using headphones. After the relaxation program has ended, your heart rhythm will be recorded for another 5-minute period while you are resting.

You will then be asked to complete the same questionnaire as before.

The entire procedure will take about 45-60 minutes. After this second questionnaire, your participation on this study will be over.

This is an investigational study. Up to 20 people will take part in this study. All will be enrolled at M. D. Anderson.
