1. MEASURING JOINT R.O.M.

2. Background Info:  Range of Motion (R.O.M.): description of how much movement exists in a joint What may inhibit range of motion?  Typical movement at joint?  Measuring Unit --- degrees

3. Active vs. Passive  Active: movement created by muscular contractions around the joint.  Passive: movement and force created by external source pushing on body around joint.  Which is greater?

4. Flexibility Training  Dynamic/Ballistic: use of momentum of body segments to extend joint position beyond R.O.M.  Static: slow stretch, maintained for several seconds.  Proprioceptive Neuromuscular Facilitation (PNF): stretching procedures involving alternating contraction and relaxation of musculature.  Debate between these three still exist.

5. Relative Reference Systems Fundamental Standing Position Anatomical Standing Position All Joints @ 0  except Ankle @ 90  Forearm varies

6. Joint Position & Displacement 00 90  140  Displacement: the difference between initial and final positions

7. More Examples…. 00 00 40  90 
