U2 Flashcards
Learning vs memory
L
-process
-acquisition of ability
M
-product
-outcome of learning
Explicit vs Implicit Memory
E
-facts/events
-consciously recalled
-needs awareness and attention
I
-observed by savings in performance
i.e., riding a bike
Types of implicit memory
Nonassociative
-increase/decrease response to stimulus
-habituation, sensitization
Associative
-learn to predict relationships
-classical conditioning
Procedural
-skills and habits
-repetition over trials
Explain the Fitts and Posner stages of motor learning
Cognitive
-understand task
-develop strategies
-variable performance
Associative
-refine the skill
-less cognitive
-improvement is slower
Autonomous
-automaticity
-low attention levels
-can focus on other aspects
What is consolidation
process by which newly gained motor skills are transformed into a more permanent memory
-some gains require time to be effective
What is the motor learning paradigm
Acquisition
-perform and practice motor skill
*can be affected by fatigue, mood, and motivation
Retention
-perform motor skill
-persistence of performance demonstrates true learning
Transfer
-performance gain in 1 task due to practice on another task
-test of generalizability
Healing considerations for muscle
-rich blood supply (fast healing)
-contracting/stretching encourages blood flow for enhanced healing
-injuries can be a result of muscle imbalance
~2-4 weeks for healing
Healing considerations for tendons
-less blood supply (can be stimulated by activities that cause tension- eccentric)
-we must gradually progress treatment as to not overload it
Healing considerations for bone
-bones heal best when load is applied
*weight bearing doesn’t mean mobilization
-promote blood flow
Healing considerations for ligaments
-less blood than muscle or tendon
-protect injury site with motion of joint
*some motion is needed to stimulate blood flow but not injure
*graded injuries 0-3
Healing considerations for cartilage
-avascular and aneural (slowest healing)
-nutrients is supplied via synovial fluid (when load is applied and removed repeatedly)
-pain is generally not felt with injury
-inactivity can thin it out
Healing considerations for nerves
-pain, muscle weakness, numbness
-slow healing rate
-important to also heal tissues around the nerve
-overstress can cause the nerve to be overreactive and more symptomatic
What are mechanical factors to tissue stress
Frequency- how often load is applied in a period
Load- amplitude, direction, rate
Repetition- how often load is applied during session
What are physiological factors to tissue stress
Modifiable factors
&
Non Modifiable factors
-metabolic, vascular, neural
Explain irritability
Amount of vigorous activity it takes to aggravate symptoms
High- easy to aggravate
Moderate- specific motions and forces cause it
Low- difficult to flare up
