Document Summary
Range-of-motion (rom: the extent of joint movement in a physiologic dof motion is the rom in that dof, > normal rom = hypermobile or flexible , < normal rom = hypomobile or restricted . 10 extension and 130 flexion for passive at the ankle: passive motion almost always has a greater range than active, less discomfort, muscle isn"t strong enough to do it actively. Joint play/laxity: the extent of a joint movement in a non-physiologic (undesirable) dof of motion is the. Joint play or laxity in that dof passive only, measured in mm or : > normal joint play = laxity , < normal joint play = restriction . Assessing joint laxity: clinicians make semi-quantitative estimates of np motion with hands; assess 2 things, joint play : extent of easy movement in a non-physiologic dof, end point feel : how quickly the joint stiffens in a non-physiologic dof.
