Answer 3

to decide surgical intervention to improve gait, quantify severity of disorder, determine outcome of operation, determine optimum placement of artifial leg

Question 4

What equipment might a gait lab ahve

Answer 4

3D motion cameras, force plates, EMG

Question 5

How many cameras need to spot a marker for it to calculate position

Answer 5

two or more

Question 6

A gait cycle is ? stride(?) - equal to ? step(s)

Answer 6

one stride -two steps

Question 7

Start and end of the gait cycle

Answer 7

Question 11

What might occur in gait if a person had a stroke

Answer 11

foot drop - weak dorsifelxion therefore foot hang during stance phase causing toes to make first cotnact not heel

Question 12

What does force plate measure

Answer 12

ground reaction force

Question 13

What does the butterfly diagram show

Answer 13

varied ground force reaction during gait

Question 14

What shape does measure gait with two froce plats give

Answer 14

double hump - first is deceleration second is foot pushing off ground
