HIGT

Question 1

what are the parameters for dosing HIGT

Answer 1

60-80% HRR or 70-85% HRmax
14-17/20 Borg
30 minutes in target zone/session preferred over intervals
2000-6000 steps/session
4 days/week preferred

Question 2

The use of gait on treadmill or overground, supported or unsupported at an aerobic intensity to facilitate neuroplasticity and reinforce gait cycle motor planning

Answer 2

high intensity gait training

Question 3

what needs to be integrated to improve motor learning

Answer 3

error

Question 4

what are the 4 important things that matter for HIGT

Answer 4

intensity
repetition
saliency
specificty

Question 5

what are the 4 subcomponents of walking

Answer 5

propulsion
limb swing
stance control
postural stability

Question 6

way to redirect the COM and propel forward

Answer 6

propulsion

Question 7

what main muscles help with propulsion

Answer 7

hip extensors and PF’s

Question 8

what % of metabolic cost of walking is propulsion

Answer 8

50-70%

Question 9

best way to improve propulsion

Answer 9

step through on steps

Question 10

pendular movement of the free limb to advance in preparation for stance

Answer 10

limb swing

Question 11

what help with limb swing

Answer 11

gravity and hip flexors

Question 12

what % of metabolic cost is limb swing

Answer 12

5-10%

Question 13

ability of swing leg to accept weight while supporting the person

Answer 13

stance control

Question 14

what % of metabolic cost of walking is stance control

Answer 14

25%

Question 15

control lateral movements and perturbations that destabilize gait

Answer 15

postural stability

Question 16

what % of metabolic cost is postural stability

Answer 16

5-10%

Question 17

example of propulsion deficit

Answer 17

limited ankle control and PF power

Question 18

example of limb swing deficit

Answer 18

hip and PF weakness may reduce walking speed and swing phase speed

Question 19

example of stance control deficit

Answer 19

quad weakness may lead to collapse

Question 20

example of postural stability deficit

Answer 20

limited motor control t/o, inability to process sensory info or using altered sensory information

Question 21

treatment for propulsion

Answer 21

increase gait speed, incline on treadmill, elastic resistance at pelvis/trunk, add ankle weights/vest

Question 22

treatment for limb swing

Answer 22

leg weight, resistance to LE (T-bands), step over obstacles

Question 23

tx stance control

Answer 23

reduce body weight support, add weighted vest

Question 24

tx postural stability

Answer 24

unstable/narrow surfaces, backwards or sideways stepping, obstacles, dual tasking
