The flashcards below were created by user cali-amber on FreezingBlue Flashcards.

  1. 2 primary muscle groups active throughout MST
    hip ABD, PF
  2. highest torque demand on muscle at any joint during gait cycle, in TST, on the
  3. muscle group that counteracts 2nd highest
    torque demand, in LR
    hip ext
  4. in initial swing, this jt motion provides
    primary means of limb clearance
    knee flexion (greatest here, 60°)
  5. this frontal plane motion reduces rotational
    stress at the ankle jt during loading
    ankle eversion (unlock midtarsal, allow flexibility of jt)
  6. normal gait velocity
    80 m/min
  7. phase of double limb support when limb is unloading body weight onto opposite limb
    LR or PSW are double support; this is PSW
  8. max amount of DF that occurs during swing
  9. max amount of DF that occurs during stance
  10. if person doesn't get heel off in TST, penalty will be
    dec C/L step length
  11. ankle clears ground by 1 cm in this phase of gait
  12. most likely cause of foot slap
    weak pre-tibials
  13. knee flex to 40° is a critical event in
  14. controlled ankle DF w/ a heel rise is a critical event in
  15. hip stability, controlled knee flex, and ankle PF are critical events in
  16. primary penalty for excess PF in TST is
    dec forward progression
  17. when a drag occurs in ISW, it is likely due to
    knee ext spasticity
  18. forefoot contact usually caused by
    excess PF in TSW
  19. excess DF and excess knee flex in TST often caused by
    weak PF w/ strong quads (collapse when trying to PF, so have to have strong quads to support bodyweight)
  20. excess PF caused by
    weak PF, weak quads
  21. inadequate knee ext in TSW may be caused by
    weak quads, patterned movment, or hamstring spasticity
  22. penalty for dec knee flex in PSW likley a compromise in
    foot clearance
  23. critical event of IC
    heel first contact
  24. critical events of LR
    hip stability, controlled knee flex and ankle PF
  25. critical event of MST
    controlled tibial advancement
  26. critical events of TST
    controlled ankle DF w/ heel rise, trailing limb
  27. critical events of PSW
    passive knee flex to 40°, ankle PF
  28. critical events of ISW
    hip flex to 15°; knee flex to 60°
  29. critical events of MSW
    hip flex to 25°, ankle DF to 0°
  30. critical events of TSW
    knee ext to neutral (possibly 5° flex)
