POSTURE PART 2 MOBILITY p.323

Question 1

In CEP settings, What is the No. 1 goal of the majority of participants?

Answer 1

to walk better

Question 2

push off or pull off uses which muscles

Answer 2

hip flexors

Question 3

foot dragging and ______ contact with flat foot and instead of _____________

Answer 3

heel,

heel strike

Question 4

Task Requirement during Walking:

Answer 4

1) Maintenance of upright posture and balance of the body
2/3 of our weight is over the pelvis
2) Control of foot trajectory to achieve safe ground clearance (or toe off (right after pushoff)) and gentle heel or toe landing (or heel contact)
3) Generation of the mechanical energy to maintain or increase walking speed
4) Absorption of mechanical energy for shock absorption and stability or to decrease walking speed at heel contact

Question 5

Which joint (muscle group) is the most important to generate the mechanical energy in walking? + Which event?

Answer 5

muscle group = ANKLE Plantarflexors event=pushoff

Question 6

Which joint + muscle are mainly involved in the absorption at heel contact?

Answer 6

Joint = Knee
Muscle = Quadriceps

Question 7

What if quadriceps is too weak?

Which compensatory mechanism is used?

Answer 7

Knee hyperextension at heel contact to ‘lock the knee’

Question 8

step length

Answer 8

distance from one foot strike to the foot strike of the controlateral foot

Question 9

Stride length

Answer 9

distance convered in two steps

Question 10

As a CEP (or Clinical Kinesiologist), if you had to assess the gait cycle of your hemiparetic client, would you choose to measure:

Answer 10

Answer: Step Length
Difference between hemi and non hemi sides
Why not stride length?
Because you would not note any asymmetry between hemi and non hemi sides

NOT SURE IF YOU ACTUALLY NEED TO KNOW THIS FOR THE EXAM

Question 11

Effect of Different Conditions on Stride Length

Answer 11

A - normal
B - painful hip
C - heiparesis
D - parkinsons disease

Question 12

AB people step cycle

Answer 12

Able-bodied people
Stance phase :   60%
Swing phase :    40%
Double support: 20%
Single support : 80%

Question 13

People with disabilities:

Stance phase : ____
Swing phase : ____
Double support: ____
Single support: ____

Answer 13

85
15
70
30

Question 14

Why such a shift in step cycle?

Answer 14

???

Question 15

Summary of Gait Changes in the Older Adult

Answer 15

1) decrease velocity
2) decrease stride length
3) increase time of oduble support
4) decrease arm swing
5) flatter foot on heel strke
6) decreased power generation at push off

Question 16

In rehab, which of these gait changes improves?

Answer 16

velocity, stride length, arm swing, time in double support DECREASES

Question 17

Decreased velocity of gait is directly due to which 2

Answer 17

arm swing

and

decreased power generation at push off

Question 18

Can you name characteristics of hemiplegic gait walking pattern?

Answer 18

Hip circumduction
No single support on affected leg (cane)
No plantarflexion/dorsiflexion on affected ankle
Left arm = rigidity

Question 19

Training involved in fall proof! book:

Answer 19

Center of gravity control (sitting and standing)
Multisensory training through altered sensory input
Postural strategy
Gait pattern enhancement and variation
Strength and endurance
Flexibility…and more!

Question 20

The somatosensory system informs us about objects in our external environment through ______ and about the _______ and movement of our body parts (proprioception) through the stimulation of muscle and joints

Answer 20

touch (i.e., physical contact with skin)

position

Question 21

Multisensory training level 1

Answer 21

All COG activities to be performed with vision distracted, reduced, or removed. All cues must focus on somatosensory inputs
