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”

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”

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”

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

Infra red radiation – types and effectsDownload http://www.physiotherapyphd.com Infra-Red Radiation: The infrared rays are electromagnetic waves with the wavelengths of 750 to 400000 nm and frequency 4 × 1014 Hz and 7.5 × 1011 Hz. It lies beyond boundary of visible light. Any hot body can produce infrared rays like the sun, electric bulb, coalContinueContinue reading “Infra-red radiation – Types and Effects”
