Vibroacoustic therapy

Last updated

Vibroacoustic therapy (VAT) is a type of sound therapy that involves passing low frequency sine wave vibrations into the body via a device with embedded speakers. [1] [2] This therapy was developed in Norway by Olav Skille in the 1980s. [3] The Food and Drug Administration determined that vibroacoustic devices, such as the Next Wave® PhysioAcoustic therapeutic vibrator, are "substantially equivalent" to other therapeutic vibrators, which are "intended for various uses, such as relaxing muscles and relieving minor aches and pains"; [4] thus, vibroacoustic devices (therapeutic vibrators) are "exempt from clinical investigations, Good Guidance Practices (GGPs), and premarket notification and approval procedures." [5]

Frequencies

Vibroacoustic therapy uses low frequency sinusoidal vibrations between 30 and 120Hz. This is similar to the range of subwoofers or vibrating theater seating. 40 Hz specifically has been widely studied in vibroacoustic therapy and a number of fields as well. [6]

Devices

Vibroacoustic devices come in a range of forms including beds, [7] [8] chairs, [9] pillows, mats, [10] wristbands, [11] wearable backpacks, [12] and simple DIY platforms. [13] They generally function by playing sound files through transducers, bass shakers, or exciters which then transfer the vibrations into the body. Some devices attempt to target very specific parts of the body such as the wrist or the spine.

Proposed mechanisms of action

One of the proposed mechanisms of action for vibroacoustic therapy is brainwave entrainment. [14] Entrainment suggests that brainwaves will synchronize with rhythms from sensory input. This further suggests that some brainwave frequencies are preferable to others in given situations.

Current practice

Vibroacoustic therapy is available at a number of spas, resorts, and clinics around the world. [15]

Vibroacoustic Therapy is closely related to Physio Acoustic Therapy (PAT) which was developed by Petri Lehikoinen in Finland. [16] Both are examples of low frequency sound stimulation (LFSS). [17] More broadly, they are subsets of Rhythmic Sensory Stimulation (RSS) which is being studied across a range of sensory modalities. [18]

Criticism

The science behind vibroacoustic therapy has been questioned by multiple sources. Some sources refer to it as pseudoscience and the TedX talk by prominent vibroacoustic researcher Lee Bartel has been tagged as falling outside of the TED talk guidelines. Practitioners of VAT do agree that more research is needed as VAT has been a largely clinical practice since its inception. Academic research published in peer reviewed journals and meeting higher scientific standards is being pursued at the University of Toronto and other institutions to address these objections. [19]

Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to induce an electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil connected to the scalp. The stimulator generates a changing electric current within the coil which creates a varying magnetic field, inducing a current within a region in the brain itself.

Tinnitus is a variety of sound that is heard when no corresponding external sound is present. Nearly everyone experiences faint "normal tinnitus" in a completely quiet room; but it is of concern only if it is bothersome, interferes with normal hearing, or is associated with other problems. The word tinnitus comes from the Latin tinnire, "to ring". In some people, it interferes with concentration, and can be associated with anxiety and depression.

<span class="mw-page-title-main">Transcutaneous electrical nerve stimulation</span> Therapeutic technique

A transcutaneous electrical nerve stimulation is a device that produces mild electric current to stimulate the nerves for therapeutic purposes. TENS, by definition, covers the complete range of transcutaneously applied currents used for nerve excitation, but the term is often used with a more restrictive intent—namely, to describe the kind of pulses produced by portable stimulators used to reduce pain. The unit is usually connected to the skin using two or more electrodes which are typically conductive gel pads. A typical battery-operated TENS unit is able to modulate pulse width, frequency, and intensity. Generally, TENS is applied at high frequency (>50 Hz) with an intensity below motor contraction or low frequency (<10 Hz) with an intensity that produces motor contraction. More recently, many TENS units use a mixed frequency mode which alleviates tolerance to repeated use. Intensity of stimulation should be strong but comfortable with greater intensities, regardless of frequency, producing the greatest analgesia. While the use of TENS has proved effective in clinical studies, there is controversy over which conditions the device should be used to treat.

Diathermy is electrically induced heat or the use of high-frequency electromagnetic currents as a form of physical therapy and in surgical procedures. The earliest observations on the reactions of high-frequency electromagnetic currents upon the human organism were made by Jacques Arsene d'Arsonval. The field was pioneered in 1907 by German physician Karl Franz Nagelschmidt, who coined the term diathermy from the Greek words dia and θέρμη therma, literally meaning "heating through".

Electrotherapy is the use of electrical energy as a medical treatment. In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulators for neurological disease. The term has also been applied specifically to the use of electric current to speed wound healing. Additionally, the term "electrotherapy" or "electromagnetic therapy" has also been applied to a range of alternative medical devices and treatments.

Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, refers to the observation that brainwaves will naturally synchronize to the rhythm of periodic external stimuli, such as flickering lights, speech, music, or tactile stimuli.

Auditory integration training (AIT) is a procedure pioneered in France by Guy Bérard, who promoted it as a cure for clinical depression and suicidal tendencies, along with what he said were very positive results for dyslexia and autism, although there has been very little empirical evidence regarding this assertion. It typically involves 20 half-hour sessions over 10 days listening to specially filtered and modulated music. It was used in the early 1990s as a treatment for autism; it has been promoted as a treatment for ADHD, depression, and a wide variety of other disorders. AIT has not met scientific standards for efficacy that would justify its use as a treatment for any condition.

Low-intensity pulsed ultrasound (LIPUS) is a technology that can be used for therapeutic purposes. It exploits low intensity and pulsed mechanical waves in order to induce regenerative and anti-inflammatory effects on biological tissues, such as bone, cartilage, and tendon. Even if the real mechanism underlying its effectiveness has not been understood yet, it is plausible that the treatment relies on non-thermal phenomena, such as microbubbles and microjets induced by cavitation, acoustic streaming, and mechanical stimulation.

Listener fatigue is a phenomenon that occurs after prolonged exposure to an auditory stimulus. Symptoms include tiredness, discomfort, pain, and loss of sensitivity. Listener fatigue is not a clinically recognized state, but is a term used by many professionals. The cause for listener fatigue is still not yet fully understood it is thought to be an extension of the quantifiable psychological perception of sound. Common groups at risk of becoming victim to this phenomenon include avid listeners of music and others who listen or work with loud noise on a constant basis, such as musicians, construction workers and military personnel.

A vibrator, sometimes described as a massager, is a sex toy that is used on the body to produce pleasurable sexual stimulation. There are many different shapes and models of vibrators. Most modern vibrators contain an electric-powered device which pulsates or throbs. Vibrators can be used for both solo play and partnered play by one or more people. Devices exist to be used by couples to stimulate the genitals of both partners. They can be applied to erogenous zones, such as the vulva, vagina, penis, scrotum, or anus, for sexual stimulation, for the release of sexual frustration and to achieve orgasm. Vibrators may be recommended by sex therapists for women who have difficulty reaching orgasm through masturbation or intercourse.

The Magic Wand aka the True Magic Wand,Magic Wand Original, Vibratex Magic Wand and Original Magic Wand) is an AC-powered wand vibrator. It was originally manufactured for relieving tension and relaxing sore muscles; however, it is most known for its use as a sex toy. Japanese company Hitachi listed the device for business in the United States in 1968. Sex educator Betty Dodson popularized its use as a vibrator and masturbation aid for women during the sex-positive movement in the late 1960s. It functions effectively as a clitoral vibrator, to bring women to orgasm. The wand is 12 inches (30 cm) long and weighs 1.2 pounds (540 g) with stimulation provided by its rubberized 2.5-inch (64 mm) head.

Therapeutic ultrasound refers generally to any type of ultrasonic procedure that uses ultrasound for therapeutic benefit. Physiotherapeutic ultrasound was introduced into clinical practice in the 1950s, with lithotripsy introduced in the 1980s. Others are at various stages in transitioning from research to clinical use: HIFU, targeted ultrasound drug delivery, trans-dermal ultrasound drug delivery, ultrasound hemostasis, cancer therapy, and ultrasound assisted thrombolysis It may use focused ultrasound or unfocused ultrasound.

Whole body vibration is a generic term used when vibrations of any frequency are transferred to the human body. Humans are exposed to vibration through a contact surface that is in a mechanical vibrating state. Humans are generally exposed to many different forms of vibration in their daily lives. This could be through a driver's seat, a moving train platform, a power tool, a training platform, or any one of countless other devices. It is a potential form of occupational hazard, particularly after years of exposure.

Audio-visual entrainment (AVE), a subset of brainwave entrainment, uses flashes of lights and pulses of tones to guide the brain into various states of brainwave activity. AVE devices are often termed light and sound machines or mind machines. Altering brainwave activity is believed to aid in the treatment of psychological and physiological disorders.

Sensory stimulation therapy (SST) is an experimental therapy that aims to use neural plasticity mechanisms to aid in the recovery of somatosensory function after stroke or cognitive ageing. Stroke and cognitive ageing are well known sources of cognitive loss, the former by neuronal death, the latter by weakening of neural connections. SST stimulates a specific sense at a specific frequency. Research suggests that this technique may reverse cognitive ageing by up to 30 years, and may selectively improve or impair two point discrimination thresholds.

Bioelectromagnetic medicine deals with the phenomenon of resonance signaling and discusses how specific frequencies modulate cellular function to restore or maintain health. Such electromagnetic (EM) signals are then called "medical information" that is used in health informatics.

NeuroIntegration Therapy (NIT) is a non-invasive combination therapy that integrates quantitative electroencephalography (qEEG or QEEG) brain mapping with additional therapies such as neurofeedback, vibroacoustic therapy, pulsed electromagnetic field therapy (PEMFT, or PEMF therapy) and photic stimulation (light therapy.)
