Q

Prosthetic Gait: TTA

A
  • MAIN GOAL of TTA gait progression:

Clinical Pearl:

When training pts, particularly during gait…

Keep these points in mind:

A
  • Efficiency of doing any activity is the ratio bw work accomplished and the energy expended
    • Work/Energy
  • This must be balanced w/ conscious effort to maintain safety of all pts***
  • May not look like normal gait** but may be **optimal for that pt***
  • Develop realistic and measurable goals that match lvl of activity and potential
73
Q

Develop realistic and measurable goals that match lvl of activity and potential

Accurate goals dictate what?

A

Accurate goals dictate type of prosth/orthotic you prescribe

74
Q

Early Gait Training:

A

TTA gait/rehab typ BETTER OUTCOMES vs TFA or high amps

75
Q

Early gait training:

TTA gait/rehab typ better outcomes vs TFA or high amps

Due to:

  • LESS prosth weight
  • LESS energy cost
  • *More anatomical jts→ more jt awareness→ incd proprio and balance
  • Less prosth parts, less alterations
76
Q

  2. Weak hip ABDs
96
Q

Gait Training: TFA

Poor socket fit (med soft tissue/groin) or

Weak hip ABDs…..

What happens and what does it do?

A

Gait Training: TFA

Manual facil/inhibit during Stance Gait

Techniques to do this:

A
  • Behind pt on posterior lateral aspect of hips
  • Fingers flared out “feeling for” motion in the frontal plane and rotation in the transv. plane
