Flashcards in POSTURE PART 2 MOBILITY p.323 Deck (22):
1

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

to walk better

2

push off or pull off uses which muscles

hip flexors

3

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

heel,

heel strike

4

Task Requirement during Walking:

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

5

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

muscle group = ANKLE Plantarflexors event=pushoff

6

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

Joint = Knee
Muscle = Quadriceps

7

What if quadriceps is too weak?
Which compensatory mechanism is used?

Knee hyperextension at heel contact to ‘lock the knee’

8

step length

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

9

Stride length

distance convered in two steps

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: 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

11

Effect of Different Conditions on Stride Length

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

12

AB people step cycle


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

13

People with disabilities:

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

85
15
70
30

14

Why such a shift in step cycle?

???

15

Summary of Gait Changes in the Older Adult

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

16

In rehab, which of these gait changes improves?

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

17

Decreased velocity of gait is directly due to which 2

arm swing

and

decreased power generation at push off

18

Can you name characteristics of hemiplegic gait walking pattern?

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

19

Training involved in fall proof! book:

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!

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

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

position

21

Multisensory training level 1

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