Q

Core Stability

A
  • core stability is instantaneous to maintain it the involved anatomy must continually adapt to changing postures & loading conditions to ensure the integrity of the vertebral column and provide a stable base for movement of the extremities

A
  • deepest of the abdominal muscles, internal to the internal oblique
  • runs horizontally attached to the lumbar vertebrae via the thoraco-dorsal fascia
  • innervated by the lower 6 thoracic nerves, iliohypogastric, & ilioinguinal nerves
  • corset like effect to stabilize the lumbar spine & pelvis before movement of the lower and/or upper limbs occur
34
Q

Describe abdominal hollowing intervention

A

palpate the transverse abdominus just distal to the ASIS & lateral to the rectus abdominus
- if TA contracts flat tension is felt but if internal oblique contracts a bulge is felt
- instruct patient to breathe in, breathe out, then gently draw the belly button in toward the spine to hollow out the abdominal region
- have patient maintain contract and resume breathing

35
Q

Describe abdominal bracing

A

-abdominal bracing occurs by setting the abdominals & actively flaring out laterally around the waist
- patient should be able to hold the braced position while breathing in a relaxed manner
- more focus on global stabilization

36
Q

To brace or to hollow?

A
  • bracing of the abdominal muscles provides greater lumbar spine stability than hollowing
    -bracing increases spine stability with minimal increase in spine compression loads
  • bracing creates patterns that better enhance stability
37

  • encased within the thoracolumbar fascia
  • atrophy, moth looking appearance on MRI, fatty infiltrate in LBP patients
38
Q

How to test for multifidus activation

A
  • patient is standing while you palpate their back along the multifidus
  • have patient either raise the contralateral arm or rock back and forth on their feet pretending to take a step
  • multifidus should contract with movement of the limbs
39

47
Q

Guidelines for spinal stabilization training: principles and progression

A

1) begin training with awareness of safe spinal motions & the neutral spine: Activation
2) have the patient learn to activate the deep stabilizing musculature while in the neutral position: Activation
3) add extremity motions to load: Acquisition
4) increase reps to improve holding capacity (endurance and increase load to improve strength: Acquisition
5) use alternating isometric contractions & rhythmic stabilization techniques to enhance stability: Acquisition
6) progress to movement from one position to another in conjunction with extremity motions: Assimilation
7) use unstable surfaces to improve the stabilizing response & improve balance: Assimilation

48
Q

Prescription of painful exercise

A
  • prescribed with instructions for patients to experience pain that is acceptable & safe
  • painful exercise reshapes the traditional belief that exercise improves biomechanics & changes at the tissue level
  • promotes relearning
  • reconceptualization the relationship between pain & tissue damage
49
Q

Describe graded exercise

A
  • graded exercise = increase exercise & activity tolerance using a quota system
  • pain intensity is monitored but not used to make decisions regarding exercise progression
50
Q

Describe graded exposure

A
  • graded exposure = exposing patients to specific situations which they are fearful during rehab
  • Example: use the FABQ to find activities fearful to patient, select the top 2-3, introduce those fearful activities, provide positive reenforcement if making progress, continue the same exposure at the same intensity if not making progression
51
Q

Exercise parameters for back pain

A
  • avoid bed rest: no benefit for healthy adults & detrimental to older adults
  • aerobic training (appears to have ‘best’ evidence): moderate to vigorous if able to tolerate (50-80% HRR) and 20-40 minutes (less not beneficial)
  • resistance training: dynamic resistance training - exercise large muscle groups of the upper & lower extremity & moderate intensity (strengthening parameters); isometric resistance training
52
Q

Describe nociceptive mechanisms

A
  • exercise decreases nociceptor excitability
  • increases peripheral inhibition
  • promotes healing of injured tissues
53
Q

Describe central mechanisms

A
  • exercise activates descending inhibitory systems with increases in endogenous opioids & altered serotonin function
  • regular exercise reduces central excitability & expression of excitatory neurotransmitters in the spinal cord, brain stem, & cortical nociceptive sites
  • regular exercise can modulate pain by altering central nociceptive processing & increasing central inhibition
54
Q

Describe neuropathic mechanisms

A
  • regular aerobic exercise increases anti-inflammatory cytokines at the site of injury & promotes nerve healing & analgesia (animal studies)
  • in people with diabetic neuropathy, decreased pain is attributed to an increase growth of epidermal nerve fibers after regular exercise
55
Q

Describe psychosocial mechanisms

A
  • greatly influences the 3 biological pain process
  • exercise improves catastrophizing, depression, cognitive dysfunction, learning, memory, & neurogenesis
  • exercise reduces negative psychological factors associated with pain, improves cognitive & social factors
