Effect of Vibroacoustic Therapy on Acute Stress in University Students

Research of Music Therapy in the Development of Persons With Special Needs

The goal of the planned Randomized Control Trial is to explore the effect of vibroacoustic therapy on acute stress of university students. The theoretical framework of the study is based on biopsychosocial model of stress and multimodal approach to measurement. The trial is designed as single-blinded, placebo-controlled, with participants individually randomized into two parallel-groups, including equal randomization and blocked allocation of participants. 420 participants are all full-time university students (18-30 years) and will be divided into two groups: an experimental group (receiving low vibrations combined with music) and a control group (only music without low-frequency sounds). For both groups acute stress response will be measured by spectral analysis of heart rate variability (HRV SA), galvanic skin response (GSR), salivary cortisol, standardized psychological questionnaires - visual analogue scales for stress (VAS-stress) and Perceived Stress Scales-10, Czech version (PSS-10). It is expected that the experimental group will demonstrate a lower level of stress response that will be measured by higher activity of parasympathetic activity, lower level of skin resistance, lower level of salivary cortisol and lower subjective perception of stress. If vibroacoustic therapy turns out to be effective, it can be viewed as safe, student-friendly and inexpensive prevention of stress-related health problems and promote the health of students in the course of university education.

Study Overview

• Status: Recruiting
• Conditions: Stress, Psychologic
• Intervention / Treatment: Other: Vibroacoustic therapy; Other: Only music (no vibrations)

Detailed Description

Primary objective: to explore whether application of vibroacoustic therapy has more significant effect on eliminating acute stress response in university students than music alone.

Research question: "Does the application of vibroacoustic therapy (low frequency vibration with music) show a more significant effect on decreasing an acute stress response (measured by HRV SA, GSR, salivary cortisol) and perception of stress (measured on VAS) in university students compared to listening to music without technologically modified low-vibrations?"

Participants: The recruitment of suitable research participants will be carried out among students studying at Faculty of Education at Palacky University in Olomouc, Czech Republic, provided that all inclusive criteria are met. Participants will be recruited by three researchers via mail and personal contact with students at the start of each of two semesters of one academic year. Only students with medium or high levels of acute stress will participate on the research experiment (level of stress measured by PSS-10, min. 20 points are required from participants). Recruiting process will be coordinated and overseen by a recruitment coordinator. Sequentially numbered, opaque, sealed envelopes will be used as a mechanism for allocation concealment. The allocation sequence will be generated at a remote workplace by a specialist not participating in enrollment and assignment of participants for the intervention.

It is a parallel group, two arms, superiority trial with 1.1. allocation ratio. Equal blocked randomization (with block size 8) with stratification according to the gender will be used here. The randomization scheme will determine which persons will be placed in the intervention group and the control group (placebo) The randomization will be implemented by a computerized random number generator (program Sealed Envelope).

The intervention is triple-blinded (blinded will be participants, statisticians as well as outcome measurements). Considering one-shot character of research experiment in every participant possibility of emergency unblinding has not been considered, nor systematic plans to promote participants´ retention and complete follow-up have not been created.

Research experiment: After recruitment students will be divided into the experimental or control groups by means of randomization. Experimental group will get full intervention including music with low-frequency sound. Control group will listen to the same music as planned for experimental group without the low-frequency sound in the frequency range 20-100 Hz (no vibrations). Measurements in two parallel groups will be carried out by two trained persons under supervision by a psychologist, physiological measurement experts and a research coordinator overseeing adherence to experimental protocols.

Measurements: The measurement methods consist of (1) heart rate variability spectral analysis, (2) galvanic skin response, (3) salivary cortisol, (4) Perceived Stress Scale questionnaire, (5) visual analogue scales for stress and (6) a questionnaire of own construction.

Statistical analysis: Data analysis methods will be based on statistical processing in the form of the one-way (factor Vibroacoustic/Placebo) repeated measures (factor Before/After) ANOVA. The intervention arm will be compared against the control for all primary analyses and significant differences in the responses of autonomous nervous system, salivary cortisol and the stress perception will be examined.

Hypotheses:

H1: Listening to vibroacoustic therapy recording (music with low-frequency vibrations) will stimulate higher levels of parasympathetic nervous activity compared to listening to music alone.

H2: Listening to vibroacoustic therapy recording (music with low-frequency vibrations) will stimulate lower levels of salivary cortisol compared to listening to music alone.

H3: Listening to vibroacoustic therapy recording (music with low-frequency vibrations) will stimulate lower levels of subjective perception of stress compared to listening to music alone.
