Range of motion is the term used to describe the degree of amplitude that a joint can achieve. It is a parameter commonly used in physical therapy semiology to functionally evaluate a limb or a particular joint. This amplitude is precisely intended to quantify the mobility of the structure to be evaluated and not to qualify, which aims only to highlight the presence of restrictions or hypermobility. Age does not change the range of motion, however, factors such as weak muscles, disease and bone structure can significantly affect it.
The cerebrospinal fluid (CSF) laboratory findings for previous meningeal hemorrhage patient would have increased amount of red blood cells. The CSF should be clear but it can become red in this patient. The CSF could also see as xanthochromia if centrifugated. Xanthochromia can be identified several days after the hemorrhage.
