Answer 8

A: 5 deg DF torque
K: Neutral w/ quad quiet gastric ^ /ext torque
H: extend torque to neutral
P: neural

Question 9

P:rotate forward.

Question 15

What is stabilizing in all planes during gait?

Answer 15

back extensors+abs

RA in MS and TS
Erectors in Preswing

Question 16

What are the functional tasks?

Answer 16

Weight acceptance
Single limb support
swing limb advance

Question 17

A visible forward then backward movement of thigh during terminal swing?

Answer 17

Past retract. just slapping it back..

decreases step length.

Question 18

What are some trunk deviations?

Answer 18

leans (lat/f/b)
rotation (cant dissociate)
help reduce load on other structures

Question 19

what are the pathological gait pattern?

Answer 19

ataxic (stagger wide BOS -cerrebellar)
Festinating (on toes PD)
Scissor (cross midline CP/CVA/TBI)

Question 20

What is included in neuroplasticity in locomotor training?

Answer 20

specificity
amount (most important)
intensity (increase it)

Question 21

Principles of locomotor training?

Answer 21

Maximize LE loading
Enhance sensory cues (fácil)
optimize kinetics (posture/coordinate)

Question 22

Training of one motor task may affect performance of biomechanically separate tasks

Answer 22

Leapfrog effect

via overlapping neural circuits

Question 23

activities of pregait?

Answer 23

parallel bars
weight shift
f/b steps
stability before mobility

Question 24

Bracing/orthotic interventions?

Answer 24

control DOF and improve mechanics

or use stimulation

Question 25

Robo gait orthosis in VR?

whats an exoskeleton

Answer 25

lokomat

preset gait parameters with auditory feedback

Question 26

What are KPKR of robot?

Answer 26

KP: audiovisual feedback

KR: step/distance/upright time

Question 27

Tx progression of environment?

other progressions?

Answer 27

gentile: stationary/predict
then unpredict
moving pred/unpred

dual task
adaptability

Question 28

Gait speed importance?

Answer 28

reflect Fx+ physiologic change
balance confidence
predictor of future.
