Lecture 2: Therex Concepts Flashcards
What are therex?
systematic, planned performance of bodily movements
What are goals of therex?
remediate or prevent impairment
improve, restore and enhance physical function
prevent or reduce health related factors
What is definition of flexibility?
ability to move without restrictions
What is neuromuscular control?
interaction of sensory and motor systems that enables muscle to anticipate/respond to proprioceptive/kinesthetic info to created coordinated movement
What are components of physical function?
- balance
- muscle performance
- stability
- NM control
- flexibility
- CP endurance
What is important to remember to help pt be effective with exercise?
incorporate pt learning style, begin simple, clear and concise instruction, provide feedback
What is motor learning?
acquisition and retention of a skilled movement or task through practice
What is difference between performance or learning?
performance- ability to carry out a skill
learning- retention of skill
What is a discrete task?
action or movement with distinct beginning and end
Ex: stretching hammys
What is a serial task?
series of discrete movements combined into a specific sequence
ex: getting up from floor
What is a continuous task?
repetitive, uninterrupted movement with no distinct beginning or end
ex: walking
What is an open environment?
objects or people around patient move or surface is unstable
What is inter trial variability?
absent- task occurs in constant environment from one performance to next (ladder)
present- variable environment from one task to next (rock climbing)
What is manipulation of objects?
performing a task requiring or not requiring UE manipulation activities
What are 3 stages of motor learning?
- cognitive stage- what to do and how to do it safely, many errors, significant feedback
- associative- focused on consistency and fine tuning, less errors, minimal feedback
- autonomous - movements are automatic, patient adapts to more challenging environments
What is a very important thing to remember about motor learning?
the task needs to be meaningful to patient
What type of practice is effective in early stages of learning?
Part practice- breaking down a whole movement into individual pieces
What is blocked order practice?
same task performed repeatedly under same conditions in predictable order
good for initial practice, 6” step up repeated
What is random order practice?
slight variations of same task performed in unpredictable order
ex: step up to unpredictable height
leads to better skill retention
What is random/ blocked order practice?
variations of the same task performed in random order and each variation performed more than once
What is intrinsic feedback?
from sensory system of pt
provides both KP and KR
What is augmented feedback?
aka extrinsic
PT provides feedback during or after task to provide KP or KR
can be verbal, tactile, auditory or visual
What is concurrent feedback?
during performance in real time
What is delayed post response feedback?
PT allows pt a short interval for pt to think about task and reflect before giving them feedback
this is important for Pt learning
What are patient related factors to exercise adherence?
do they understand their condition, do they understand exercise program, what is their level of motivation
What factors related to health condition could affect adherence?
acuity, chronic, severity, stability
What are program related variables to adherence?
is program too complex, what was quality of instruction or feedback
