Symptoms typically worse if positioned in a posture too long. This position or posture doesnt have to be weight bearing

Question 6

Define sustained muscle contraction as a functional loss characteristic

Answer 6

Patient uses the same muscle groups for sustained periods of time in a small range. Ex. working at a keyboard for several hours

Question 7

When are functional loss characteristics typically identified?

Answer 7

During the subjective and objective exam
