ROM	the extent of movement that occurs at a joint
Joint movement	ROM- active, passive, or a combination of both
AROM Active range of motion	is the arc of motion through which the joint passes when voluntarily moved by muscles acting on the joint
PROM Passive range of motion	is the arc of motion through which the joint passes when it is moved by an outside force
Normally PROM is slightly greater than...	AROM
ROM is measured by an instrument or toll known as....	Goniometer
Fucntional range of motion	descibes the minmum range of motion needes to execute performance in essntial areas of occupation without the use of special equipment
Planes of movement	Sagittal, Frontal, Horizontal
Goniometer	the tool most widly used to measure joint ROM in the clinical environment
Stationary bar	a small protractor (half circle) of 0 to 180 degress or a full corcle printed with a scale from 0 to 360 degress
Moveable bar	is attached at the center or axis of the protractor and acts as a dial
Sagittal plane	Flexion and extension occur in this anatomical plane around the coronal axis
Frontal plane	Abduction ans Adduction occur in this anatiomical plane around the anteroposterior axis
Horizontal plane	Shoulder internal rotation and external rotation occur in this anatomical plane
Types of Goniometers	Full circle Radiopaque Plastic Finger Plastic small
OT must have complete understanding of	1)the degree and type of motion that will occur at a specific joint 2)average or normal ROM 3)how to position herself and the patient during measurement
