Abstract

Due to the increasing burden on healthcare budgets of musculoskeletal system disease and injury, there is a growing need for safe, effective and simple therapies. Conditions such as osteoporosis severely impact on quality of life and result in hundreds of hours of hospital time and resources. There is growing interest in the use of low magnitude, high frequency vibration (LMHFV) to improve bone structure and muscle performance in a variety of different patient groups. The technique has shown promise in a number of different diseases, but is poorly understood in terms of the mechanism of action. Scientific papers concerning both the in vivo and in vitro use of LMHFV are growing fast, but they cover a wide range of study types, outcomes measured and regimens tested. This paper aims to provide an overview of some effects of LMHFV found during in vivo studies. Furthermore we will review research concerning the effects of vibration on the cellular responses, in particular for cells within the musculoskeletal system. This includes both osteogenesis and adipogenesis, as well as the interaction between MSCs and other cell types within bone tissue.

Core tip: Low magnitude, high frequency vibrations are attracting growing interest as a non-invasive therapy for a variety of different disorders. The number of studies aimed at elucidating the effects of vibration both in vivo and in vitro is increasing rapidly. This review aims to provide an introductory overview of the in vivo data for a broad range of human applications and animal models. In vitro work is covered in more detail, focusing in particular on studies concerning the effects of vibration on cells derived from the musculoskeletal system.
