HIGT Flashcards
what are the parameters for dosing HIGT
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
The use of gait on treadmill or overground, supported or unsupported at an aerobic intensity to facilitate neuroplasticity and reinforce gait cycle motor planning
high intensity gait training
what needs to be integrated to improve motor learning
error
what are the 4 important things that matter for HIGT
intensity
repetition
saliency
specificty
what are the 4 subcomponents of walking
propulsion
limb swing
stance control
postural stability
way to redirect the COM and propel forward
propulsion
what main muscles help with propulsion
hip extensors and PF’s
what % of metabolic cost of walking is propulsion
50-70%
best way to improve propulsion
step through on steps
pendular movement of the free limb to advance in preparation for stance
limb swing
what help with limb swing
gravity and hip flexors
what % of metabolic cost is limb swing
5-10%
ability of swing leg to accept weight while supporting the person
stance control
what % of metabolic cost of walking is stance control
25%
control lateral movements and perturbations that destabilize gait
postural stability
what % of metabolic cost is postural stability
5-10%
example of propulsion deficit
limited ankle control and PF power
example of limb swing deficit
hip and PF weakness may reduce walking speed and swing phase speed
example of stance control deficit
quad weakness may lead to collapse
example of postural stability deficit
limited motor control t/o, inability to process sensory info or using altered sensory information
treatment for propulsion
increase gait speed, incline on treadmill, elastic resistance at pelvis/trunk, add ankle weights/vest
treatment for limb swing
leg weight, resistance to LE (T-bands), step over obstacles
tx stance control
reduce body weight support, add weighted vest
tx postural stability
unstable/narrow surfaces, backwards or sideways stepping, obstacles, dual tasking
