what is the difference between 2-point and modified 2-point gait?

A

modified 2-point gait only uses 1 AD

47
Q

what is swing-to/swing-through referring to?

A

swinging the involved limb either to (next to AD)

or

swinging it through (past the AD)

48
Q

what is step-to/step-through referring to?

A

stepping the involved limb to (next to AD)
or

stepping it through (past the AD)

49
Q

how should an individual ascend stairs with an AD?

A

up with good leg

bring bad leg up

bring AD up last

50
Q

how should an individual descend stairs with an AD?

good leg comes last
