Week 1: Mobility and Posture Flashcards
to maximize pt mobility, the therapist must…
- understand the contexts of the pt interventions
- learn specific mobility techniques
- develop decision-making skills
every outcome is an interaction between ____ , ____ , and ____
person, task, environment
what is the purpose of rehabilitation?
to enable pts to engage as fully as possible in life activities they find meaningful
what does AMAP/ANAP mean?
as much as possible, as normally as possible
what does CCDD mean?
- control centrally, direct distally
- controlling a movement is best done closer to the center of mass
- directing a pt’s movements is best done distally
what are some general principles of rehab?
- responding to contexts of pt care
- skillfully employing mobility techniques
- applying the best decision-making principles to every intervention
define center of mass
a point representing the mean position of the matter in a body or system
define force
- any interaction that, when unopposed, will change the motion of an object
- F = mass x acceleration
define lever/moment arm
- Length between a joint axis and the line of force acting on that joint
- Every joint that is involved in an exercise has a moment arm
- Longer moment arm = bigger load
define torque
- twisting force that tends to cause rotation
- T = moment arm x force
what types of forces may act on the body?
- linear vs angular
- internal vs external
- gravity
- friction
what are the types of loading?
- tensile
- compressive
- distractive
- shear
- bending
- torsion
- combined
what are some consequences of loading?
- compression and bending at the spine can lead to injury if twist too much or the wrong way
- putting load on a bone can be a good thing because it strengthens the bone, but too much of a load can cause injuries
- friction and pressure on the skin
define base of support
the contact area of an object with its supporting surface
define stabilization
ability to hold one attachment site while allowing the other attachment site to move
define static stability
- maintaining and controlling the body’s orientation in space
- usually done by keeping center of mass within base of support
define dynamic trunk stabilization
more stability in the core = better stability for the entire body
define controlled mobility
- center of mass intentionally moves beyond the BOS and back within the BOS
- ex: running
define uncontrolled mobility
falling or slipping
define open kinetic chain
- non weight bearing
- distal segment is free to move in relation to the proximal segment
- ex: bicep curls, leg extension
define closed kinetic chain
- weight bearing
- distal segment stabilized, proximal segment moves in relation to it
- ex: squats, push-ups
