Attention began to return to these properties and the possibilities of using very low current for healing in the mid-1900s. In a study published in 1969, for example, a team of researchers led by L.E. Wolcott applied microcurrent to a wide variety of wounds, using negative polarity over lesions in the initial phase, and then alternating ...
A transcutaneous electrical nerve stimulation (TENS or TNS) 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 ...
This is distinct from transcutaneous electrical nerve stimulation (TENS), in which an electric current is used for pain therapy. "The main difference is the desired outcome. TENS unit is a medical device for pain relief. The desired outcome is to reduce pain by stimulating different nerve signals.
Nerve signals are frequency modulated; i.e. the number of action potentials that occur in a unit of time is proportional to the intensity of the transmitted signal. Typical action potential frequency is between 4 and 12 Hz.
Transcranial direct current stimulation (tDCS) Transcranial random noise stimulation (tRNS) 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 ...
An electrosurgical unit (ESU) uses high currents (e.g. 10 amperes) at high frequency (e.g. 500 kHz) with various schemes of amplitude modulation to cut or coagulate; As a treatment for fibrillation or irregular heart rhythms: see Defibrillation and Cardioversion; As a method of pain relief: see Transcutaneous electrical nerve stimulation (TENS)
A smart device is an electronic device, generally connected to other devices or networks via different wireless protocols (such as Bluetooth, Zigbee, near-field communication, Wi-Fi, NearLink, Li-Fi, or 5G) that can operate to some extent interactively and autonomously.
An indoor location tracking map on a mobile phone. Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. . Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers of the network and the phone or by simply
