1
Q

“Artificial” or “deliberately created” rather than arising naturally or spontaneously; Purpose is to use a sensory system to get a motor response; Use early on as an adjunct to treatment

A

Contrived treatment technique

  • intervention is temporary; PT needs to fade back use of techniques
  • uses input system to get motor response

Q

What are the proprioceptive deep sensory receptors?

A
  1. Muscle Spindle - found in belly of muscle; use for facilitation
  2. GTO - Found at ends of muscle (PROX/DIST); Used for inhibition
  3. Joint Receptors - joint capsule, ligaments; Used for facilitation; ex. approximation to help postural muscles kick in and they stand

Q

How do use the GTO to get more ROM in a person who has spasticity?

A
  • Stretch the muscle - SLOW/ PROLONGED stretch, so spastic m. has a chance to respond might feel m. “let go” at some point, and get more range
  • have to evaluate if it’s worth it in terms of PT progress (incr ROM may only last 10 mins), BUT if pt feels better after/for the rest of the day after, it might be useful to add to ther ex

A
  1. Golgi type endings - largest, respond to rate of joint movement and gravity
  2. Paciniform endings - respond to rapid joint movements, deep pressure, and vibration
  3. Rufinni’s endings - respond to rate and direction of joint movement
  4. Free nerve endings - signal joint pain

Q

What does joint approximation facilitate?

Study These Flashcards
A
  • Activates joint receptors
  • Facilitates joint motion
  • Enhances joint awareness
  • Improve mobility, relieve muscle spasm, reduce pain
  • Contraindication: hypermobile or unstable joints
17
Q

What are the proprioceptive inhibitory techniques?

Study These Flashcards
A
  1. inhibitory stretch
  2. Hold-relax method/ contract relax
  3. full body rotation - helps with widespread rigidity/ spasticity; disassociate the body
  4. oscillations - inhibits spasticity
  5. Low frequency vibration (<75 Hz)
18
Q

Deep, maintained stretch along the longitudinal axis of tendons with positioning; Prolonged positioning in lengthened range; Activates GTO; Prolonged weight bearing to dampen tone; Weight bearing on a spastic arm; Inhibitory (serial) casting

Study These Flashcards
A

inhibitory stretch

19
Q

What ROM position should you use for inhibition? facilitation?

Study These Flashcards
A 
inhibition = midrange to shortened position
facilitation = lengthened position
20
Q

What spinal column contains exteroceptive input?

Study These Flashcards
A

Dorcal column

  • large, well myelinated
  • apply to gate theory to inhibit stimuli from spinothalamic tracts
21
Q

What are exteroceptive facilitation techniques?

Study These Flashcards
A
  1. Intermittent Contact - Facilitate contraction, sensory awareness, directional cues, security/support; NDT approach comes from this
  2. Light Touch - Brief, light contact with the skin can facilitate; brief swipe of ice cube, light pinch; used in more involved pts
22
Q

What are exteroceptive inhibitory techniques?

Study These Flashcards
A
  1. maintained firm pressure
  2. slow repetitive stroking - paravertebral stroking 3-5 mins

27
In the middle ear ______ detects horizontal movement, while ______ detects vertical movement. _______ detects rotation.
utricle; saccule (otoliths) | semicircular canals
28
What type of vestibular stimulation inhibits tone, relaxes, and decreases arousal?
Slow vestibular movements - slow rhythmic movements - rolling or rocking
29
What type of vestibular stimulation increases tone, and arousal, while improving motor coordination and posture?
rapid vestibular stimulation - useful in pts with hypotonia and bradykinesia (DS, PD pop) - can activate sympathetic response
30
Reflex maintiaing the stability of an image during rapid head movements (keeps it in focus, etc)
Vestibuloocular reflex
31
Reflex of head, neck, trunk m. activation movements to keep head upright during movement of the body
vestibulospinal reflex
32
What causes stimulation of parasympathetic system?
relaxation/ inhibitory 1. Maintained firm pressure 2. Slow repetitive stroking 3. Prolonged icing 4. Neutral warmth 5. Deep breathing 6. Relaxation exercises
33
What are the possible PNF techniques that can be used?
1. Rhythmic Initiation 2. Alternating Isometrics or Rhythmic Stabilization 3. Slow Reversals 4. Agonist Reversals
34
Passive movements; Progressing to active assistive and active movements; Move the patient through the desired movement; “1, 2, 3, and up”; Indicated for spasticity, rigidity, difficulty initiating movements, motor planning and learning deficits, aphasia
Rhythmic initiation
35
Apply resistance with hands and change placement; Patient maintains a position using isometric contraction; Build up resistance gradually; PT moves hands quickly; Use command – “don’t let me move you”; Avoid holding breath; Indicated for impaired strength, coordination, and control, if ROM limitations
Alternating isometrics or rhythmic stabilization | - improves stability
36
Concentric contraction of agonist then antagonist against resistance; Move through full ROM; Indicated for impaired strength and coordination between muscle groups or if patient fatigues quickly; PT moves hands
Slow reversal
37
Concentric contraction through available ROM followed by a hold then eccentric contraction moving slowly back to starting position; Used in antigravity activities; Indicated for weak postural muscles, difficulty with eccentric control of body weight, poor dynamic postural control; Hands stay in same place
Agonist reversal
