GONIOMETER
The term of goniometr is derived from two Greek words,gonio meaning angle and metron, meaning measure.A goniometer is an instrument used to measure angle.With in the field of phisical therapy,goniometry is used to measure the total amount of avalible motion at a specific joint.
Goniometry can be used to measure both active and passive range of motion.goniometer are produce in a variety of size and shap and are usually constructed of either plastic or metal.
Goniometer a protractor like device commonly with a 180 degree range used to measure a joint’s position and accurately described abnormal fixed joint position.
TYPE OF GONIOMETER
Universal goniometer
Gravity depend goniometer or fliud goniometer
Pendulum goniometer
Electrogoniometer
UNIVERSAL GONIOMETER
It is designed by Mr. Moorethis very commonest variety.it is having stationary arm,movable and body.
GRAVITY DEPEND GNIOMETER OR FLIUD GONIOMETER
It is also called as pelvic inclinometer .it is designed by sehenkar in 1956.
.It is heaving gravity effecting pointer and the fluid filled chamber with the air bubbles .it is mostly used for the measuring the pelvic tilt or drop.
PENDULAR GONIOMETER
It is designed by Fax and Van breemen in 1934.it consist of 350 degree protractor with the wighed pointe
ELECTROGONIOMETER It is designed by karpovich in 1959.it has two arms.1 is attached with the proximal segment and another is attached with the distal segment of the measuring joint.[it is mostly used for the research purpose.
IMPORTANT OF COMPONENTS OF GONIOMETER
Ostiokinematics and Arthrokinematics of joint.
Axis and Plane of movement.
Types of ROM.
ROM of individual joint
End feel
Capsular and nun Capsular
ARTHROKINEMETICS
Movment of joint surface
OSTEOKINAMETICS
Movement of shafts of the bone
PLANE,AXIS AND MOVEMENT
