|---|---|---|---|---|---|
| what are the different causes of somatic dysfunction? | Disruption of one element, Disrupted interrelationship of elements, Loss of integrity of the whole system
🗑
|
||||
| summarize the counterstrain hypothesis of dysfunction: | muscle is responsive tissue, nervous system coordinates, proprioceptive system manages spatial relationship (primary hypothesis), model of learned behavior
🗑
|
||||
| summarize the nociceptive hypothesis of dysfunction: | central sensitization, long term potentiation, genetic changes in spinal interneuron pool
🗑
|
||||
| information from sensory receptors to the central nervous system (CNS) is what nerve? | afferent
🗑
|
||||
| information from the CNS to functional motor end organs is what nerve? | efferent
🗑
|
||||
| nerve endings of unmyelinated C fibers-sensing of noxious (harmful) stimulus, i.e. pain defines what? | nociception
🗑
|
||||
| which efferent nerves run from CNS to extrafusal fibers (outside the muscle spindle in the muscle belly)? | alpha motor nerves
🗑
|
||||
| which efferent nerves run from CNS to intrafusal fibers (within the muscle spindle)? | gamma motor nerves
🗑
|
||||
| which model of somatic dysfunction tends to be functional, emphasizing how things are regulated? | neuroregulatory model
🗑
|
||||
| which model of somatic dysfunction tends to emphasize asymmetric position and resistance of motion? | postural structural model
🗑
|
||||
| the neurological model of somatic dysfunction has what three tenets? | Altered or dysfunctional proprioceptive reflexes, Sustained Reflex to nociception, or a combination of both
🗑
|
||||
| the strain-counterstrain model of somatic dysfunction has what four tenets? | trauma or sudden strain causes proprioceptive dysregulation; spindle afferents send inaccurate muscle; lack of co-ordination of agonist and antagonist; and dysfunctional hypertonia creates tenderness and is painful
🗑
|
||||
| what are the 4 elements of reflex coordination? | Sensation-a stimulus and sensor; Connectivity to an association area; Connectivity a motor response element;A loop of ongoing traffic
🗑
|
||||
| where do proprioceptors occur? | Muscles, Tendons, Joints, Fascia, Labyrinth of the ear, and Vision
🗑
|
||||
| name a highly specialized sensory organ of a muscle unit that senses stretch and rate of stretch | muscle spindle
🗑
|
||||
| what can muscle spindle proprioceptors detect? | Absolute joint position, change in position, rate of change (velocity), and force (acceleration)
🗑
|
||||
| what is the strain-counterstrain hypothesis? | Inappropriate co-ordination of alpha and gamma motor systems within muscle (voluntary and involuntary systems); mismatched resting tone between muscle and its reflex linked antagonist, and sustained contraction causes pain
🗑
|
||||
| what is the nociception hypothesis? | A pain event, once initiated, can facilitate muscle contraction at the segmental cord level, with central mediation, including increased sympathetic tone
🗑
|
||||
| how does counterstrain resolve tender point-nociception to pressure? | Shortening the muscle, holding for 90 seconds, slow return to neutral
🗑
|
||||
| in the counterstrain theory, what happens to a hyper-shortened muscle? | it gets suddenly lengthened
🗑
|
||||
| how does counterstrain seem to work? | turning off the gamma afferent signal by shortening the muscle
🗑
|
||||
| what is the evidence that supports Nociceptive model of Somatic Dysfunction | pain associated with clinical complaint of dysfunction; anatomical circuits support the hypothesis; animal data (including spinalized preparations) of hypertonia in response to noxious stimuli; alteration of reflexes by pharmacologic blocking of pain rece
🗑
|
||||
| what is an example of the difference between pain and nociception? | nociception is when you touch something hot-your brain tells you to move your hand before the sensation of pain is felt

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
