PHTY103 Lecture Notes - Lecture 12: Endolymphatic Hydrops, Benign Paroxysmal Positional Vertigo, Inner Ear
Document Summary
Patient population: 60+ age group (both genders) those that have had brain surgery. Intervention: finger to nose test (depth perception, 9 peg hole test (fine motor control, trace the maze test (motor control) Comparator: test the effectiveness of each individual test, give one test to the third of the population - repeat until all is distributed (alternatively have some people doing more than one test) Outcome: the improvement in coordination in the patients, this is effective assuming variables limited. Muscle: deforms gradually under low load (elastic region, then after significant amount of deformation, responds more stiffly through to failure (during plastic region) In comparison of point of ultimate failure (stress at end of curve), muscle appears stronger than bone, but weaker than tendon. Bone: stiffest of the 3 tissues (steepest curve) i. e. more. Causes of decreased coordination after brain injury: medications: a number of commonly used medications can cause dizziness, lightheadedness and decreased balance.
