Introduction

In the last decade, WBVT has become an increasingly popular subject of scientific research and is used in practice for instance in the field of sports medicine [1-3]. To date, WBV training is considered to be effective and well-suited for older patients and is considered a safe and effective preventive intervention for unfit people [4,5]. The intensity of WBVT basically is regulated by the frequency, the amplitude and the body position on the device [1]. It must be differentiated between PBVs, where only parts of the body were exposed to vibrations and WBVs. Also it must be differentiated between methods using indirect applications of vibrations like WBVT, where the vibrations travel through some parts of the body to the muscles the intervention aims at, and directly applicated vibrations on the muscle belly or the respective tendon [6,7].

By engaging in WBVT, an increase in muscular capacity (maximum force, speed and strength) can be achieved that is comparable to effects of strength training, as well as positive effects on the postural control, the flexibility and the bone health [4,5,8,9]. An advantage of WBV training is that the effects on the muscular capacity can be achieved by performing 2 to 3 training sessions per week, each lasting only 10 to 15 minutes [4,5]. Additionally, WBV training requires fewer skilled employees, as participants can perform the exercise independently after appropriate instruction. Furthermore, the highly stimulatory nature of a WBV training device as well as the minor expenditure of time, potentially causes a high compliance rate.

Manufacturers often state, that WBVT was invented for the prevention of the negative effects of zero gravity on astronauts respectively cosmonauts. It is a fact, that the therapeutic application of vibrations is not an independent development of the 20th century. This article will give an oversight on the historic evolution of WBVT and shows what we can learn from it for research and application of such interventions nowadays.

Historic evolution of WBVT

The therapeutic application of vibrations in fact is a very old method. There is evidence on the therapeutically use of vibrations already in ancient times by the Greek and the Romans [10,11]. For example,WBVs wereapplicated by riding on horses or donkeys as well as the ride in a two wheeled carriage with irregular wheels driven on rough stone-flagged roads [10]. For the therapeutic application of vibrations on parts of the body the Greeks used saws wrapped in cotton fabric [12]. Also Lucius Annaeus Seneca (1-65) described the ride in a carriage as beneficial for preserving health [13].

In the 16^th century a Japanese book describes the potential benefits of vibrations for the health [14]. In this case the application of vibrations for the relief of rheumatic disorders and the support of the cure of fractured bones by the application of vibrations was described. Nowadays, acute rheumatic diseases are often mentioned to be a contraindication, but studies on this topic are currently underway. In contrast, contemporary studies confirm a general positive effect of WBVT on the bone health [15]. In the 18th century Charles Irenee Castel de Saint-Pierre, better known as “Abbe de Saint-Pierre” (1658- 1743), invented the so-called “tremoussoir” respectively “fauteuil de poste” for the use on infirm persons to achieve positive effects on their nervous system. With this device he actually convinced the outmost critical Fran�ois Marie Arouet, better known as “Voltaire” [16,17].

Forerunners of the 19^th century

In 1808 John Barclay wrote the book “The Muscular Motion of the Human Body”, in which he described a case muscular spasm cured with the application of vibrations [18]. Contemporary studies underline this effect, by indicating that there is a positive effect of WBVT on muscular spasm [19]. Overall, in the early 19^th century vibrations applied on humans by mechanical devices (forerunners of modern devices) were frequently used in therapy to reduce morbidity, support the cardiovascular system, digestion and to treat nervous diseases [10,17]. Today, such devices are used in therapy to treat chronic diseases, like neurodegenerative diseases or chronic low-back pain, and physical infirmities [20]. In the late 19^th century mechanical devices for the application of WBVs were highly recommended and at the same time criticized [11]. Below, three outstanding examples for forerunners of today’s devices are described.

Zanders medico-mechanicaltherapy

Since approximately 1864 the Swedish physician Gustav Zander (1835-1920) build and tested mechanical devices able to apply WBVs driven devices predominantly used for therapeutic purposes and used them lateron in his numerous institutes. One of these devices was the “Zanderapparat F2”, which simulated the jog trot on a horse [11,17,21,22]. Already the frequency as well as the amplitude could be varied on this device.

Jean-Martin Charcot’s vibrating chair

Based on anecdotic reports of his patientssuffering from Parkinson’s disease indicating that longer train-or carriage rides lead to a considerably reduction of their pathology, theFrench neurologist Jean-Martin Charcot (1825-1893) started to experiment with WBVs at the end of his career [16,17,23]. He simulated the at train-or carriage rides occurring vibrations with a specially invented chair. Hereby he was able to reduce their pathology and enhance their well-being bya daily applicationof 30 minutes [16,23]. Today’s studies underline these positive effects of vibration training on the symptoms of Parkinson’s disease [24]. Charcot was able to vary the frequency, the vibration direction and its intensity. Much more important, he noticed that a therapeutic intervention with WBVs has to be tailored to the individual patient and his needs. Today, this is discussed intensely again [16,25].

John Harvey Kellogg: pioneer of modern WBVT

John Harvey Kellogg (1852-1943) might be the most popular pioneer of modern WBVT [12,26]. He invented vibrating chairs, barsand platforms as can be found on the market today and used them in his “Battle Creek Sanatorium” for therapeutic measures. The first generations were steam driven and these devices allowed to applicate WBVs as well as PBVs and could be used by up to five individuals [11].

Further development and improvements between 1960 and 1985

At the beginning of the 20th century the therapeutic use of WBVs seemed to be vanished into thin air, maybe due to the impact of the two world wars.

In the 1960s Professor Biermann developed the “Rhythmischeneuromuskulare Stimulation” (RNS), which isthe direct forerunner of today’sdevices [12,27]. Since 1970 this method was further developed by Vladimir Nazarov and used by the athletes of the Russian Olympic team in numerous disciplines [12,28]. Nazarovtransferred the RNS in actually realizable exercise interventions [12,20,25]. Nazarov and Spivak were the first to realize that there is a connection between an increase in muscular capacity and the application of WBVs respectively PBVs [20,25]. Today, WBTV is widely used in competitive sports in many team sports and individual sports, like Basketball or Golf. It seems to be especially reasonable during warming up and cooling down and for flexibility training [29].

WBVT: Entry in popular sports and modern therapy

In the late 90s, one of the first to engage in the use of WBVT in popular sports wasGuus van der Meer (former coach of the Dutch Olympic team. He developed theprobably to date most popular device for WBVT, the Power Plate [12]. In 1996 the first side-alternating device was certificated in Germany [20]. This specific kind of device is frequently used in therapy today (Figure 1).
