An electrode is "stereotactically" guided to the site using magnetic resonance imaging and once in place, the electrode is activated by subcutaneous leads attached to a pulse generator under the skin. It is effective in treating refractory post-stroke pain, atypical face pain, anaesthesia dolorosa, and deafferentation and somatic pain such as ...
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 ...
Scrambler therapy involves the use of electronic stimulation on the skin with the goal of overwhelming pain information with non-pain information. [1] In a therapy session, "electrocardiographic-like pads are placed around the area of pain". [2] Limited research has been done on the effectiveness of scrambler theory. [3]
The electrodes are generally pads that adhere to the skin. The impulses mimic the action potential that comes from the central nervous system , causing the muscles to contract. The use of EMS has been cited by sports scientists [ 2 ] as a complementary technique for sports training, and published research is available on the results obtained. [ 3 ]
The most common use of SCS is failed back surgery syndrome (FBSS) in the United States and peripheral ischemic pain in Europe. [4] [5]As of 2014 the FDA had approved SCS as a treatment for FBSS, chronic pain, complex regional pain syndrome, intractable angina, as well as visceral abdominal and perineal pain [1] and pain in the extremities from nerve damage.
The "Muscle Whistler", shown here with surface EMG electrodes, was an early biofeedback device developed by Harry Garland and Roger Melen in 1971. [16] [17]An electromyograph uses surface electrodes to detect muscle action potentials from underlying skeletal muscles that initiate muscle contraction.
Functional electrical stimulation has been found to be effective for the management of pain and reduction of shoulder subluxation, as well as accelerating the degree and rate of motor recovery. Furthermore, the benefits of FES are maintained over time; research has demonstrated that the benefits are maintained for at least 24 months.
Intramuscular EMG can be performed using a variety of different types of recording electrodes. The simplest approach is a monopolar needle electrode. This can be a fine wire inserted into a muscle with a surface electrode as a reference; or two fine wires inserted into muscle referenced to each other.
