Range Of Motion

Limitation of the range of motion can suggest the muscle systems involved (11). Determine if decreased range of motion affects any activities, including walking, standing, bending over, sitting, climbing stairs, or raising arms over the head.

Range of motion can be evaluated with the following graded scale:

None Normal

Mild Slight motion loss, <15%, with minimal clinical significance

Moderate Loss of up to 50%, and is clinically significant

Marked Loss of 50% or greater in a major joint

Rigid No motion in a major joint

Limitation of range of motion should be differentiated from stiffness. Stiffness may indicate a resistance to movement and often accompanies pain and discomfort. It is typically brief and may be relieved as activity progresses. Prolonged inactivity, such as sitting or sleeping, and strenuous activity, such as exercise, can be followed by stiffness.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
