Magnetic Field

Magnetic FieldDownload http://www.physiotherapyphd.com Definition: This is the area or zone of influence around a magnet in which its magnetic forces are apparent. This field may be considered as being made of magnetic lines of force which has the following properties. 1.They travel from north to south, which is the path a north pole would take.ContinueContinue reading “Magnetic Field”

Properties of Skin

http://www.physiotherapyphd.com Properties of SkinDownload Properties of Skin http://www.physiotherapyphd.com The Properties of the skins are nonlinearity, viscoelasticity, anisotropy, loading history dependency, failure properties, and aging effects. Nonlinearity There are differences in the skin of the same individual depending on location on the body, and there are differences between individuals. There are also directional effects of skin,ContinueContinue reading “Properties of Skin”

Properties of LASER

Properties of LASERDownload http://www.physiotherapyphd.com Properties of LASER: The laser differs from the ordinary light in the following ways: 1. Monochromaticity: This means that the laser light has a single color (mono-single, chromaticity—coloration). This is because the lasers are of a single wavelength and thus the definite frequency. Ordinary light however has many wavelengths. 2. Coherence:ContinueContinue reading “Properties of LASER”

Physical Therapy Treatment for Sinusitis

Physical Therapy Treatment for SinusitisDownload http://www.physiotherapyphd.com Treatment for Sinusitis Sinusitis is the inflammation and or infection of sinuses. It can cause mild to major discomfort and can have varying symptoms. The sinuses are air-filled spaces within the bones of the face. They are located in the cheeks (maxillary), forehead (frontal) and around the eyes (ethmoidal).ContinueContinue reading “Physical Therapy Treatment for Sinusitis”

Indications of Biofeedback

Indication of BiofeedbackDownload Biofeedback is an instrumentation and technique which is used to accurately measure, process and feedback some reinforcing information via auditory or visual signals by electronic or electromechanical device especially for therapeutic purposes. Peripheral nerve injuries: Biofeedback can be used in the treatment of recovering peripheral injuries. Spinal cord injury: Biofeedback techniques haveContinueContinue reading “Indications of Biofeedback”

ICE TOWELS METHOD OF CRYOTHERAPY

ICE TOWELS METHOD OF CRYOTHERAPYDownload ICE TOWELS METHOD OF CRYOTHERAPY http://www.physiotherapyphd.com Ice towels: This is a popular method of application because there is little danger of producing an ice burn. Prepare the ice solution by filling a bucket or bowl with two parts of flaked or crushed ice to one part water in which twoContinueContinue reading “ICE TOWELS METHOD OF CRYOTHERAPY”

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”

Short question Electrotherapy-3

Short Questions-3 ElectrotherapyDownload (Each question is for 2(two) marks) http://www.physiotherapyphd.com 1.Define Rheostat: Rheostat is a device used to regulate current by altering either the resistance of the current or potential in the part of the circuit. It consists of a coil of high resistance wire wound onto an insulating block with each turn insulated fromContinueContinue reading “Short question Electrotherapy-3”

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”

Infra-red radiation – Types and Effects
