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.
TENS devices are generally for external use and are non invasive treatments, [61] although the term TENS is also applied electrical stimulation via electrodes placed in the vagina or anal canal. TENS devices may be purchased by consumers and used at home. Other neuromodulation techniques involve invasive placement of electrodes. [61]
Sacral nerve stimulation, also termed sacral neuromodulation, is a type of medical electrical stimulation therapy.. It typically involves the implantation of a programmable stimulator subcutaneously, which delivers low amplitude electrical stimulation via a lead to the sacral nerve, usually accessed via the S3 foramen.
A gyroscopic wrist exerciser. Video showing the use - from starting the rotation with a 'shoestring' over various movements with the holding hand until stopping the rotor with the second hand. The demonstrated speeds are, in part, very high and not recommended for normal exercise due to the resulting high forces.
Device used to perform CES. Cranial electrotherapy stimulation (CES) is a form of neurostimulation that delivers a small, pulsed, alternating current via electrodes on the head. [1]
Tenodesis grasp and release is an orthopedic observation of a passive hand grasp and release mechanism, affected by wrist extension or flexion, respectively.It is caused by the manner of attachment of the finger tendons to the bones and the passive tension created by two-joint muscles used to produce a functional movement or task (tenodesis).

Trigeminal nerve stimulation (TNS) or external Trigeminal nerve stimulation (eTNS) is a non-invasive, non-medication therapy for Attention deficit hyperactivity disorder approved in the United States by the FDA for the treatment of ADHD in children ages 7–12.
