COMPUTERIZED GAIT ANALYSIS

Question 1

force sensors at each of the four corners

gives centroid, direction, and magnitude of the force for each sample

subjects may change gait to hit the plate

most clinical use when combined with motion analysis

very expensive systems

Answer 1

force plate analysis

Question 2

started with Harris death mat analysis which requires an ink pad and having the patient stand on a piece of paper to create a foot print

flat mat for stepping on barefoot

sensorized gait track, 12’ long

shoe systems more useful

can see pressure represented at various times through the gait cycle

of even greater use in showing timing of various events in the gait cycle

can determine center of mass movements

Answer 2

pedobarographs

Question 3

studies kinematics and kinetics

place high reflection markers at the ends of the solid links

link segment modeling

Answer 3

motion analysis

Question 4

computer aided design

non weight bearing scanners capture the shape of the foot

topographical map of the foot from the scanner

weight bearing scanners cannot lock the MTJ

lab advantages

Answer 4

Cad Cam

Question 5

attaching electrodes to specific muscles to see how they are working

strength cannot be calculated from electrical activity

Answer 5

EMG
