Flashcards in POSTURE PART 2 MOBILITY p.323 Deck (22):
In CEP settings, What is the No. 1 goal of the majority of participants?
to walk better
push off or pull off uses which muscles
foot dragging and ______ contact with flat foot and instead of _____________
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
Which joint (muscle group) is the most important to generate the mechanical energy in walking? + Which event?
muscle group = ANKLE Plantarflexors event=pushoff
Which joint + muscle are mainly involved in the absorption at heel contact?
Joint = Knee
Muscle = Quadriceps
What if quadriceps is too weak?
Which compensatory mechanism is used?
Knee hyperextension at heel contact to ‘lock the knee’
distance from one foot strike to the foot strike of the controlateral foot
distance convered in two steps
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
Effect of Different Conditions on Stride Length
A - normal
B - painful hip
C - heiparesis
D - parkinsons disease
AB people step cycle
Stance phase : 60%
Swing phase : 40%
Double support: 20%
Single support : 80%
People with disabilities:
Stance phase : ____
Swing phase : ____
Double support: ____
Single support: ____
Why such a shift in step cycle?
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
In rehab, which of these gait changes improves?
velocity, stride length, arm swing, time in double support DECREASES
Decreased velocity of gait is directly due to which 2
decreased power generation at push off
Can you name characteristics of hemiplegic gait walking pattern?
No single support on affected leg (cane)
No plantarflexion/dorsiflexion on affected ankle
Left arm = rigidity
Training involved in fall proof! book:
Center of gravity control (sitting and standing)
Multisensory training through altered sensory input
Gait pattern enhancement and variation
Strength and endurance
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)
Multisensory training level 1
All COG activities to be performed with vision distracted, reduced, or removed. All cues must focus on somatosensory inputs
