Q

Forward Reasoning

A
  • have a pre-existing expectation and looking for information that fits
  • uses past experiences
  • “if, then” pattern recognition

Palpation objectives

A

“can only be learned by palpation”

  • detect abnormal tissue texture and location
  • detect asymmetries of position
  • detect sensitivity to palpation/pressure
  • detect changes in findings to note improvements/regressions of symptoms

Q

Passive ROM

  • enables the examiner to detect pain, give an indication of true joint mobility, and assess the tissue that is limiting the motion (end feel)
  • provides info about integrity of joint surfaces and extensibility of joint capsule and associated ligs

Tension curve with MMT

A

  • HS are strongest in sitting at about 45 deg flexion

Q

Short Vs Long lever resistance

A

  • longer lever arms may be indicative of more functional demands (hip abd, shoulder flex, scapular mm)
  • examiner should apply resist near distal end of segment where muscle attaches
  • keep in mind functional demands
  • be cautious of excessive strain on joints

A
  • patient cannot hold pressure steady, decreases even though they seem to be holding the head in the flexed position

293
Q

Gait cycle initial contact to midstance

A
  • where glut max and med peak
  • foot intrinsics ecentrically lengthen as foot pronates…activate to convert foot into rigid structure through supination
