Effect Of Vibroacoustic Stimulation Research Articles

Effects of Vibroacoustic Stimulation on Psychological, Physiological, and Cognitive Stress.

Global stress is widespread in today's post-pandemic world of political and economic uncertainty. Vibroacoustic technology is a vibrotactile intervention with multiple uses, but its impact on stress lacks interpretation. This research assessed if the vibroacoustic technology of a Vibroacoustic Sound Massage (VSM) can reduce psychological, physiological, and cognitive stress. The Perceived Stress Scale (PSS-10) and electrocardiogram (ECG) and electroencephalogram (EEG) biosignals were used to quantify results. Participants were divided into Low-Stress and High-Stress groups. The ECG results show VSM increased parasympathetic activity for all participants, with the Low-Stress group being more affected. The EEG results indicate increased concentration, reduced arousal, and increased relaxation, with participant well-being non-significantly affected, though variability in this metric was homogenised after VSM. Together, these results validate VSM as an effective support tool for stress management; however, further research is required.

Effect of vibroacoustic stimulation on athletes recovering from exercise.

In sports requiring multiple short bouts of high-intensity exertion, recovery while off the field is an important part of being an effective competitive athlete. This study investigated the potential of vibroacoustic stimulation to aid recovery from athletic stress. University of Pittsburgh club and varsity athletes (n = 22) pedaled on a stationary bike strenuously, followed by a period of recovery accompanied by vibration using a wearable transducer. Subjective and physiological (skin conductance responses and cardiac measures) were used to determine the extent of recovery with frontal electroencephalographic (alpha/theta) measures indexing brain reactivity. Vibrations rated as the most calming by each participant were associated with increased high-frequency heart-rate variability, representing parasympathetic tone, particularly in athletes most affected by pedaling. Yet, EEG markers, while related to subjective recovery, were not associated with physiological change. This work provides support for the idea that vibration, which is subjectively rated as calming, could affect physiological recovery from physical stressors, at least for those individuals whose physiology is affected by exertion. This is likely through direct effects on physiology rather than "top down" effects on the brain.

Effects of vibroacoustic stimulation in music therapy for palliative care patients: a feasibility study.

BackgroundThe present study aimed at examining whether methodological strategies from a previously implemented study design could be transferred to the evaluation of the psychological and physiological effects of a music therapy intervention working with vibroacoustic stimulation in palliative care.MethodNine participants suffering from advanced cancer took part in single-sessions of music therapy, lasting for 30 min. The live music therapy intervention utilized singing chair sounds and vocal improvisation. Visual analogue scales (VAS) were used to assess self-ratings of pain, relaxation, and well-being before and after each session. During the intervention, we continuously recorded heart rate variability (HRV) as a measure of autonomic functioning. Data collection was complemented by a semi-structured interview to explore subjective experiences in more detail. Feasibility was defined as the ability to complete 80 % of the sessions in accordance with the study protocol.ResultsIn 5 out of 9 sessions (55 %) it was possible to deliver the intervention and obtain all data as intended. VAS assessment was feasible, although graphical and statistical examination revealed only marginal mean changes between pre and post. HRV recordings were subject to artifacts. While HRV parameters differed between individuals, mean changes over time remained relatively constant. Interview data confirmed that the individual perception was very heterogeneous, ranging from “calming” to “overwhelming”.ConclusionThe criterion of feasibility was not met in this study. Physiological data showed high attrition rates, most likely due to movement artifacts and reduced peripheral blood flow in some participants’ extremities. Examination of individual-level trajectories revealed that vibroacoustic stimulation may have an impact on the autonomic response. However, the direction and mechanisms of effects needs to be further explored in future studies.Trial registrationGerman Clinical Trials Register – DRKS00006137 (July 4th, 2014).

The Effect of Vibroacoustic Stimulation and Music on Fetal Movement

Introduction Fetal movement started at the 7th weeks of pregnancy and by the end of pregnancy will gradually be perfect and harmonious. Near-term fetuses can discriminate acoustic features, such as frequencies and spectra, and process complex auditory streams. In this study, we aimed to evaluate fatal movement in response to music and vibration stimulation. Materials and Methods This study is a clinical trial that was conducted in two groups and two-steps. Participants were pregnant women (primigravida) who have referring to the Shahid Beheshti Hospital in Isfahan during 2013 to receive routine prenatal care. The 64 pregnant women (32-36 weeks) were randomly assigned to the groups of Vibroacoustic stimulation (n= 32) and Music (n=32). They were stimulated immediately after the first non stress test and before the second test. The researchers’ evaluated and analyzed possible changes in non-stress test results using SPSS software version 20. Results Mean age of the subjects in vibroacoustic group and in music group were (25.5±2.6) (24.9±4.4) respectively. Paired t-test showed there was no relationship between the average number of acceleration of the fetal heart rate before and after the intervention (P>0.05).On the other hand, there was a significant correlation between the average number of fetal movements in the music group before and after the intervention (P<0.05). ConclusionMothers listen to music has led to increase their perception of fetal movements and increased number of fetal movements. So perhaps the music can use for the evaluation of fetal movement in high-risk mothers or mothers who complain of decreased fetal movements. As a result, the music may be used as a tool for assessment of fetal well-being.

The effect of vibroacoustic stimulation on the nonstress test at gestational ages of thirty-two weeks or less

The effect of vibroacoustic stimulation on the nonstress test at gestational ages of less than or equal to 32 weeks was studied in 15 patients who underwent a total of 316 nonstress tests starting at 20 to 25 weeks' gestation. There were 168 nonreactive nonstress tests that were followed by 3 seconds of vibroacoustic stimulation. The incidence of reactive nonstress tests after vibroacoustic stimulation was significantly increased after 26 weeks' gestation. This may have clinical applicability and may be related to functional maturation of the fetal auditory system.
