Biomechanical FOR 1 Flashcards
What did Baldwin do
Was the first person to analyze activities and to determine the use of joints and muscles during purposeful activities
What terms did Taylor coin
Passive range of motion
active assistive range of motion
resistive extension
muscle Reeducation
What is the theoretical base consist of for the biomechanical frame of reference
Kinetics
kinematics
A&P
What Is kinetics
Forces that balance and stabilize and dynamic forces that mobilize
What is kinematics
The study of form of motion
look at velocity and speed of movement
how forces act on the body as it moves in space
What is A&P
Look at tissue elasticity healing and muscle strength and how much energy is expended during an activity
What are some assumptions of the biomechanical for
Motion underlies all performances and daily occupation
purposeful activities can be used to remediate deficits in range of motion strength and endurance
once regained the individual automatically regain function
the principle of rest and stress applies
need to have an intact brain
Causes of decreased joint range of motion
Connective tissue surrounding the joint can limit full-motion edema scarring injury adhering of tissue around joint
What are the components in capacity of motion
Joint range of motion
strength-force = movement
Endurance
What is endurance
The ability to sustain muscle activity overtime
What is endurance dependent on
Amount of oxygen needed and the amount of work completed
What do you need to create strength
Stability and motion
What Happens when you exert force
You get movement
Movement does what
Either stabilizes or moves us
When Does dysfunction occur in strength
Disease or trauma and partners that innervate these muscles or tissues of extremity (ALS, GB, Lou Gehrig)
Types of range of motion
Passive range of motion
active assistive range of motion
active range of motion
Went to use Passive range of motion
You use when patient patient doesn’t have range of motion
When you use active assistive range of motion
When partial range of motion is present
first asked patient to move as far as they can go therapist then assists to full range of motion
What is active range of motion
Patient is able to move body part independently through full range of motion
What does range of motion do
Keeps integrity of joints
Reduces contractures, pain, deformity
makes patient easier to handle
Factors affecting goniometry testing
Time of day change in temperature prior activities emotional distress pain fear medications
Assessment for range of motion
Goniometry
What is end feel
Muscular end feel-muscular tension limits range of motion of the joint
Bony end feel- 2 bones stop range of motion of the joint
soft tissue end feel-soft tissue comes in contact with itself
Who Coined the term purposeful activity
Baldwin
