Vibroacoustic stimulation is typically used during a nonstress test (NST). [1] [2] In 2013, the Cochrane Database of Systematic Reviews concluded that there was insufficient evidence from randomized trials to support its use to assess fetal well-being in labor. [3]
Vibroacoustic devices come in a range of forms including beds, [8] [9] [10] chairs, [11] [12] pillows, [13] mats, [14] [15] wristbands, [16] wearable backpacks, [17] and simple DIY platforms. [18] They generally function by playing sound files through transducers, bass shakers, or exciters which then transfer the vibrations into the body. Some ...
Later on, they compared the results of the adaptive stimulation system with traditional stimulation set manually on two patients, and found that the adaptive approach was as effective at controlling symptoms as constant stimulation. [18] [19] The AlphaDBS implantable system by Newronika was developed and CE-marked in 2021. A systematic study ...
In order to affect brain (neuronal) activity, sensory stimulation must be within the frequency range of roughly 0.5 to 25 hertz (Hz) [citation needed]. Touch, photic and auditory stimulation are capable of affecting brain wave activity. A large area of skin must be stimulated to affect brainwaves, which leaves both auditory and photic ...
Brief stimulation produces adaptation which occurs and recovers while more prolonged stimulation can produce slower and more lasting forms of adaptation. [2] Also, repeated sensory stimulation appears to temporarily decrease the gain of thalamocortical synaptic transmission. Adaptation of cortical responses was stronger and recovered more ...
An undefined dose and target of radiation can destroy healthy cells during a treatment procedure. Non-invasive brain tissue stimulation targets a large area of poorly characterized tissue. The inability to localize the effect of stimulation makes it challenging to target stimulation only to the desired neural networks. [44] [45]
Smart materials, also called intelligent or responsive materials, [1] [page needed] are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds.
Bilateral stimulation is a generalization of the left and right repetitive eye movement technique first used by Shapiro. Alternative stimuli include auditory stimuli that alternate between left and right speakers or headphones and physical stimuli such as tapping of the therapist's hands or tapping devices.
