The FDA said patients should make sure to discuss any prior medical history, including concurrent forms of brain stimulation, current diathermy treatment, previous brain surgery, depression ...
Typical stimulation protocols used in clinical FES involves trains of electric pulses. Biphasic, charged balanced pulses are employed as they improve the safety of electrical stimulation and minimize some of the adverse effects. Pulse duration, pulse amplitude and pulse frequency are the key parameters that are regulated by the FES devices.
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 .
In layman's terms, this electrical stimulation mimics the action of healthy muscle to improve function and aid in retraining weak muscles and normal movement. Functional Electrical Stimulation (FES) is commonly used in 'foot-drop' following stroke, but it can be used to help retrain movement in the arms or legs. [citation needed]
In 2018, a major review of upper limb interventions following stroke found significant positive effects for constraint and task specific-therapies and the supplementary use of biofeedback and electrical stimulation. However, they concluded that the use of Bobath therapy was not supported. [19]
Neurostimulation is the purposeful modulation of the nervous system's activity using invasive (e.g. microelectrodes) or non-invasive means (e.g. transcranial magnetic stimulation or transcranial electric stimulation, tES, such as tDCS or transcranial alternating current stimulation, tACS).
A microcurrent electrical neuromuscular stimulator or MENS (also microamperage electrical neuromuscular stimulator) is a device used to send weak electrical signals into the body. Such devices apply extremely small microamp [uA] electrical currents (less than 1 milliampere [mA]) to the tissues using electrodes placed on the skin.
Transcranial pulsed current stimulation (tPCS) tRNS stimulation differs from tDCS in that instead of constant direct current delivery, current levels are randomly generated, with a normal distribution around a specific mean intensity. Other parameters related to the stimulation electrodes, like position and size, are similar to tDCS.
