Q

cramp

A
  • Severe, painful muscle contractions lasting seconds to minutes. High-frequency discharges of MNs overstimulated by sensory and motor tract input cause cramps.
  • Occurs when excitatory input overwhelms inhibitory input, leading to uncontrolled muscle spasm

Q

fasciculation

A
  • Quick twitches of all muscle fivers in a single motor unit and are visible on the surface of the skin

Q

fractionation

A
  • Ability to activate individual muscles independently of other muscles. Essential for normal movement of the hands. Without it, the fingers and thumb would act as a single unit
  • Rubrospinal and lateral corticospinal tract

A
  • Inability to use language in any form. Pt cannot produce speech, comprehend language, speak fluently, read, or write. Damage to much of the left cerebrum

17
Q

hyper-reflexia

A
  • Excessive reflex response to passive muscle stretch.
  • Caused by reduced descending inhibition of MNs and subsequent development of MN excessive excitability
18
Q

hypertonia

A
  • Excessive resistance to stretch of a muscle at rest
  • Produced by neural input to muscles and/or by changes within the muscle
19
Q

hypotonia

A

Decreased muscle tone, LMN sign

20
Q

intrinsic feedback

A
  • Inherent (pain)
  • Feedback from self or visual feedback from mirror
21
Q

lower motor neuron lesion/syndrome

A
  • Hyporeflexia, decrease or loss of reflexes, paresis or paralysis, atrophy, decrease or loss of muscle tone, fibrillations
22
Q

motor control

A

Process of initiating, directing, and grading purposeful voluntary movement

23
Q

motor learning

A
  • Study of the acquisition and/or modification of movement
24
Q

motor program

A

A structured set of neural commands that are organized and stored in the CNS, these programs enable the execution of coordinated movements without the need for conscious control of every individual muscle action

25
muscle hyper-stiffness
Known as spasticity or hypertonia, is a condition characterized by increased muscle tone and resistance to passive movement. Can manifest as stiffness, rigidity, and involuntary muscle spasms
26
Neurodevelopmental Treatment (NDT)
Focuses on the assessment and treatment of individuals with movements disorders by promoting normal movement patters and inhibiting abnormal postural and movement reflexes
27
paralysis
inability to move
28
paresis
weakness
29
paraplegia
affects the body below the arms
30
proprioception (conscious)
Awareness of body position in space
31
Proprioceptive facilitation
While PNF is a type of neuromuscular facilitation, this term can be used more broadly to describe any technique that uses sensory input, especially proprioceptive input, to influence muscle activity and movement
32
Proprioceptive Neuromuscular Facilitation (PNF)
Stretching technique that aims to improve flexibility and range of motion by stimulating the body’s proprioceptors
33
reflex
Involuntary motor response to external stimulus; no brain input needed
34
rigidity
Increased resistance to movement in both flexor and extensor muscles, direct facilitation of alpha motor neurons. Velocity independent
35
spasm (neuro-muscular)
A neuromuscular spasm is an involuntary and often forceful contraction of a muscle or muscle group. These spasms can be caused by various factors, including electrolyte imbalances, neurological conditions, or even overexertion
36
spasticity
- Velocity dependent hypertonia - Caused by absence of corticospinal activation of inhibitory interneurons and/or disinhibition of reticulospinal tract
37
tetraplegia
affects all four limbs
38
tone (muscle)
Resistance encountered when the joint of a relaxed pt is moving passively. A state of muscle tension or continuous activity, involuntary contraction state of a muscle
39
upper motor neuron lesion/syndrome
Decreased inhibitory input from the upper motor neuron
40
Wernicke's aphasia
Language comprehension is impaired. Easily produce speech but the output is meaningless
41
feed-forward
Consists of anticipatory motor impulses that prepare the body for movement
