21
Q

distance from the toe of the trailing limb of heel of the leading limb

swing

33
Q

phase of bipedal gait when LE is contacting ground

A

stance

34
Q

phase of bipedal gait when LE swinging through air preparing for next impact

A

35
Q

while walking, typical gait cycle lasts _____; stance phase is about ___ % and swing phase is ____ %

A

1 sec
60%
40%

36
Q

during ____ phase, distal end of kinetic chain is FIXED by ground reactive forces, so this is ______ motion

A

stance phase

closed chain motion

37
Q

(3) sub phases of stance phase

A

contact
midstance
propulsive

38
Q

during ___ phase, distal end of kinetic chain is FREELY mobile, so it is a ______ motion

A

swing

open chaing

39
Q

more than _____ cycles are performed daily

A

5,000

40
Q

2 periods of DOUBLE limb support (initial and terminal), when the CONTRALATERAL foot is in contact w/ ground
intermediate period of single limb support, when CONTRALATERAL limb is in swing phase

A

limb support during stance

41
Q

absorbing the shock; first 27% of stance phase

begins at touchdown (heel strike), ends when entire forefoot makes ground contact (foot flat)

*period when COG is “vaulting” over foot

A

midstance

43
Q

utilize energy to move up & forward
final 33% of stance
begins moment heel leaves ground (heel lift); ends when tip of phalanges no longer make ground contact

A

propulsive

44
Q

stance phase in ____: increase speed and need for more forceful propulsive periods changes the timing of events

A

running
