Day 3 Lectures Flashcards
Proprioceptive
stimuli produced within an organism by movement of its tissue
Neuromuscular
ability of muscles to initiate, produce strength, endurance, relax
Facilitation
increase ease of performance of any action resulting from lessening nerve resistance
Irradiation
spread of facilitated segment to an inhibited segment of the body
ex: band pull active SLR
Combination of isotonics
series of contractions moving from isometric to eccentric to connect
ex: tempo based training
Reciprocal inhibition
activation of one muscle group will cause relaxation or inhibition of opposing muscle group
ex: hamstring strength hold relax
Phasic shakes
over-activity of global muscles in attempt to achieve a local muscle activity
ex: rep hold producing a twitching like response of a muscle group
Contract-Relax
activation/contraction of an agonist muscle group followed by relaxation to promote increased range
ex: hamstring contract-relax
Hold-Relax
activation of an antagonist muscle group follow by relaxation to promote increased range
ex: hip flexor/quad contract-relax to promote SLR motion
PNF role in mobility
relaxation
neuromuscular control
motor mapping
vascularity
reduced fear avoidance
improves mechanics
Manual contact of PT affects
strength
direction of movement
facilitation
Concentric cueing
push or pull
Eccentric cueing
slowly let me win
back off 1%
Isometric cues
keep it there
don’t let me move there
Types of resistance
- Coordination (focus on control)
- ROM (resistance throughout range)
- Strength (resistance gradually increases)
- Initiation (resistance at beginning)
- Stabilization (slowly applied resistance)
- Relaxation (light resistance)
Traction
elongation of segment to increase muscle response to segment’s core muscle
Approximation
compression of a segment to promote stability, often used when facilitating WB positions
purpose of pelvic pnf
- identify ability of lumbar spine to side bend during pelvic movements
- utilize pelvic pattern to increase spinal, SI, hip capacity
- facilitate rolling
- facilitate pelvis with LE movemetn
pelvic patterns in midstance
pelvis should position in posterior depression with strong core activation
Heel strike opposite leg and pelvic patterns
pelvis on toe off side should passively move into posterior elevation
Toe off and pelvis
pelvis goes into anterior elevation
Heel strike same leg and pelvis
pelvis drops into anterior depression
Pelvic Objective Tests
- gait
- lumbar side bend
- lumbar extension
- leg swing
- seated slump
- pelvic drop
What should be avoided during AE to PD
- rotating trunk backwards
- moving too wide
- elevating into neck
- pulling too hard into neck
PD to AE reminders
- excursion is less than other motion
- avoid lumbar rotation
- multifidus and QL should be active
Functional purposes of rolling
- improves strength and coordination to help with mass/independent movement and control of extremities
- develops NM patterns used in more complex activities like vestibular and controlling abnormal reflexes/tone
Active elongation
use of neurophysiological principle of reciprocal inhibition. as pt activates antagonist, agonist is inhibited
can help to improve mobility
