Motor point

Motor pointDownload http://www.physiotherapyphd.com Motor point is that point where the nerve enters the muscle or impulses have maximum contraction at that point. It is usually located at a point of upper one-third and lower two-thirds of the length of muscle. When electrical stimulation is applied to produce a muscle contraction, one electrode should be placedContinueContinue reading “Motor point”

Capacitor

CapacitorDownload Capacitor also known as Condenser http://www.physiotherapyphd.com The capacitance of an object is the ability of the body to hold an electrical charge. The unit of capacitance is farad. The capacitor ability depends on the surface area and its material used. Three types of capacitors: Parallel plate capacitor is the capacitor which is used mostContinueContinue reading “Capacitor”

Kromayer lamp- UVR

Kromayer lampDownload Kromayer lamp http://www.physiotherapyphd.com Kromayer Lmp is one of the UVR generator uses water for the lamp. It has advantage over high-pressure mercury lamp that it can be used in contact with the body tissues as the harmful infrared rays are absorbed by the circulating water so there is no danger of burns. ConstructionContinueContinue reading “Kromayer lamp- UVR”

Faradic current

Faradic currentDownload Faradic current http://www.physiotherapyphd.com During the 1830s, Faraday discovered that bidirectional electrical currents could be induced by a moving magnet. He called this current “Faradic current.” Faradic current can be used to produce muscle contractions. Faradic type current is short duration interrupted direct current with pulse duration of 0.1–1 ms and frequencies between 50–100ContinueContinue reading “Faradic current”
