Vibration detection: its function and recent advances in medical applications

Abstract

Vibrations are all around us. We can detect vibrations with sensitive skin mechanoreceptors, but our conscious awareness of the presence of vibrations is often limited. Nevertheless, vibrations play a role in our everyday life. Here, we briefly describe the function of vibration detection and how it can be used for medical applications by way of whole body vibration. Strong vibrations can be harmful, but milder vibrations can be beneficial, although to what extent and how large the clinical relevance is are still controversial. Whole body vibration can be applied via a vibrating platform, used in both animal and human research. Recent findings make clear that the mode of action is twofold: next to the rather well-known exercise (muscle) component, it also has a sensory (skin) component. Notably, the sensory (skin) component stimulating the brain has potential for several purposes including improvements in brain-related disorders. Combining these two components by selecting the optimal settings in whole body vibration has clear potential for medical applications. To realize this, the field needs more standardized and personalized protocols. It should tackle what could be considered the “Big Five” variables of whole body vibration designs: vibration amplitude, vibration frequency, method of application, session duration/frequency, and total intervention duration. Unraveling the underlying mechanisms by translational research can help to determine the optimal settings. Many systematic reviews on whole body vibration end with the conclusion that the findings are promising yet inconclusive. This is mainly because of the large variation in the “Big Five” settings between studies and incomplete reporting of methodological details hindering reproducibility. We are of the opinion that when (part of) these optimal settings are being realized, a much better estimate can be given about the true potential of whole body vibration as a medical application.

Reporting Guidelines for Whole-Body Vibration Studies in Humans, Animals and Cell Cultures: A Consensus Statement from an International Group of Experts

“…WBV has attracted significant attention in sports and rehabilitation, especially to increase muscle activity [1][2][3], improve muscle function [1,4], and enhance bone mass and morphology [5][6][7] and several other medical outcomes [8][9][10]. In addition, WBV appears beneficial for cognitive function [11][12][13][14]. However, despite the convincing evidence in favor of WBV, controversial findings have been found for specific outcomes [15,16], and its clinical relevance has been questioned for specific populations [17,18].…”

The Changes of Ergonomic Engine Vibroacoustic Response Regarding Their Development

“…However, it seems very interesting, especially in light of the increasingly popular alternative power sources. In one of the recently published articles [19], the authors emphasized (and proved) the necessity to develop the field (Delphi47 program) of examining the impact of vibrations on human health. Unfortunately, this field is not very widely developed towards ergonomics.…”

Estratégia De Intervenção Sistematizada Da Equipe Multidisciplinar No Processo De Decanulação Da Traqueostomia

“…A sensibilidade vibracional é percebida pelo corpo e a informação recebida é transmitida ao cérebro por intermédio dos mecanorreceptores que comunicam as informações percebidas através da medula espinhal e do tálamo para o córtex somatossensorial. As informações vibracionais são processadas por diversas regiões do cérebro cortical (OROSZI et al, 2020).…”
