9- Normal Control of Mobility Flashcards
What is the ability to adapt to meet the individual’s goals and the demands of various environmental contexts?
Adaptability?
What are the aspects of swing phase?
- Initial swing 2. Mid swing 3. Terminal swing
What is the number of steps within a unit time often denoted as steps/min
Cadence (frequency)
What is the main idea behind transfer tasks dealing with progression?
movement in a desired direction (such as getting up from a chair from sitting to standing)
What is progression?
the ability to generate a rythmic stepping pattern to move the body
What is postural control?
the ability to ensure orientation and stability
What are the requirements for mobility?
Progression Postural Control Adaptability
What is the main idea behind transfer tasks when concerned with stability and postural control?
postural control
What is the main point of transfer tasks when dealing with adaptability?
changing tasks and environmental conditions
What is the main idea behind swing phase when concerned with adaptability?
avoidance of obstacles by swing foot
What are some ways to analyze gait?
Kinematic description Muscle activity (EMG) pattern Joint kinematics
Why do we need postural control?
the ability to control our body’s position in space is fundamental to everything we do.
What is the distance between contralateral foot strikes?
Step length
What do getting up from a chair, walking, running, climbing stairs, or navigating through a store all involve?
mobility
What is sufficient foot clearance needed for?
stability and postural control during locomotion
What is the distance from one foot strike to the next for the same foot?
Stride length
What is the ability to support the body against gravity?
Stability/Postural Control
What is the main point of stair walking when dealing with adaptability?
changed in stair environment
What are the two main phases of gait and their respective perscentages of the gait cycle?
Stance Phase (starts when the foot strikes the ground)= 60% Swing Phase (starts when the foot leaves the ground)= 40%
Why do we need mobility?
mobility is a key feature of our independence as human beings
What at the aspects of stance phase?
- Intial contact 2. Loading response 3. Mid-stance 4. Terminal stance 5. Preswing
What is velocity?
meters/second in research 40 feet or for 6 min (examples) in clinic
In rehabilitation, it is important for PTs to have a thorough understanding of ______ on the foundation of _____ and _____ necessary to accomplish mobility function and adapt to complex environmental situations.
mobility stability strength
What is the main part of swing phase when concerned with stability and postural control?
repositioning of the limb in preparation for weight acceptance
What is often the primary goal of patients?
to regain mobility
What is the main idea behind stance phase when concerned with adaptability?
changes in speed and direction or alterations in the support surface
What is the important part of swing phase during progression?
advancement of the swing leg to reposition the limb and make sure toes clear the ground
What is adaptability?
the ability to adapt gait to changing task and environmental requirements
What is the main part of stance phase when concerned with stability and postural control?
vertical forces support the body mass against gravity
What is the ability to generate forces that can move the body in a desired direction (and initiate and terminate movement)?
Progression
What the main idea behind stair walking when it comes to stability/postural control?
control of the CoM within a constantly changing base of support
What the main point of stair walking that deals with progression?
generating of forces to propel the body upstairs (concentric) or to control the body’s descent downstairs (eccentric)
What is the important part of stance phase during progression?
stabilizing limb for weight bearing and generating forces to move the body for continued motion
