STATICS AND COMPENSATION TERMS

Question 1

abnormal motion of bone caused by unresisted forces at a time when joints should have been stable?

Answer 1

hypermobility

Question 2

partial dislocation of a joint resulting from hypermobility

Answer 2

subluxation

Question 3

change of structure, position or function of one part in an attempt by the body to adjust to a deviation of structure, position, or function of another body part

Answer 3

compensation

Question 4

name this type of compensation:

motion in which the foot moves to adjust for irregularities of the supporting terrain, or deviations in the position of any part of the trunk or lower extremity

Answer 4

normal compensation

Question 5

name this type of compensation:

motion in which the foot moves to adjust for abnormal structure or function of the trunk or lower extremity

Answer 5

abnormal compensation

Question 6

name this abnormal compensation

structural inversion of the forefoot on the rear foot when the MTJ is locked (maximally pronated)

compensation seen in which the STJ pronation through mid stance and propulsion

Answer 6

forefoot varus

Question 7

name this abnormal compensation

rear foot STJ neutral position is inverted

compensation seen is which STJ pronation during midstance to equalize ground reactive forces across the plantar foot

Answer 7

rearfoot varus

Question 8

name this abnormal compensation

soft tissue contracture causing forefoot to be inverted on the rear foot

compensation seen in which there is supination of the LMTJ creating osseous instability of the forefoot

usually caused by influence of tight gastro/soleus complex and its effects on the foot

Answer 8

forefoot supinations

Question 9

name this abnormal compensation

first metatarsal is structurally plantar flexed

compensation seen in which supination of the STJ found in the contact period

if pronation occurs, no adaptation to terrain or absorb shock well and results in muscle imbalances

Answer 9

rigid plantar-flexed first ray
