Q

Prosthetic causes for Lateral bending

A
  • Prosthesis too short
  • An improperly shaped lateral wall may fail to provide adequate support for the femur
  • High medial wall may cause lean away to minimize discomfort
  • A prosthesis aligned in abduction may cause a wide-based gait, resulting in lat lean

Q

Prosthetic causes for Abducted gait

A
  • prosthesis too long
  • too much abduction built into prosthesis
  • high medial wall–> pressure on ramus
  • improperly shaped lateral wall doesn’t support the femur well
  • pelvic band positioned too far away from pt body

Q

Amputee causes for circumdected gait

A
  • abd contracture of residal limb
  • lack confidence for fllexing the prosthetic knee bc of mm weakness/fear of stubbing toe

Q

Prosthetic causes for Rotation of the prosthetic foot on heel strike

A
  • too much resistance t lantar flexing by thePF bumper/ heel wedge

Q

Amputee causes for Uneven arm swing on prosthetic side

A
  • bad balance
  • fear/insecurity w/ uneven timing
  • habit pattern
17
Q

Prosthetic causes for Uneven timing of steps

A
  • improperly fitting socket causing pain & desire to shorten stance phase on prosthetic side
  • weak extension aid/insufficient friction in prosthetic knee causes excessive heel rise–> prolonged swing-through
  • alignment stability
18
Q

Amputee causes for Uneven arm swing on prosthetic side

A
  • mm weakness
  • bad balance
  • fear/insecurity
19
Q

Prosthetic causes for Uneven heel rise

A
  • knee joint have insufficient friction

- inadequate extension aid

20
Q

Amputee causes for Uneven heel rise

A

-amputee using more power than needed for knee flex

21
Q

Rapid forward movement of that shank allowing the knee to reach maximum ext w/ too much force before heel strike

A

Terminal swing impact

22
Q

Prosthetic causes for Terminal swing impact

A
  • insufficient knee friction

- too strong knee extension

23
Q

Amputee causes for Terminal swing impact

A

-Amputee makes sure of full knee extension by deliberalty and forcibly extending residual limb

24
Q

Prosthetic causes for Instability of prosthetic knee

A
  • knee jn too far ahead of the TKA line
  • insufficient initial flex built into socket
  • PF resistance too great–> knee buckling at heel strike
  • failure to limit DF leads to incomplete knee control
25
Q

Amputee causes for Terminal swing impact

A
  • hip extensor weakness

- severe hip flex contracture

26
Q

Prosthetic cause for Lateral whips

A
  • excessive IR of prosthetic knee
  • too tight socket fit
  • excessive valgus in prosthetic knee
  • badly aligned toe-break in a conventional foot–> twisting on toe-off
27
Q

Prosthetic cause for Medial whips

A
  • excessive ER of prosthetic knee
  • too tight socket fit
  • excessive valgus in prosthetic knee
  • badly aligned toe-break in a conventional foot–> twisting on toe-off
28
Q

Amputee causes for Medial/Lateral whips

A

-Faulty walking habits

29
Q

Prosthetic causes for Foot Slap

A

-PF resistance is too soft

30
Q

Amputee causes for Foot Slap

A

-amputee may be driving the prosthesis into the walking surface too forcibly to assure knee extension

31
Q

Downward movement of the trunk as the body moves forward over the prosthesis

A

Drop off at the end of stance phase

32
Q

Prosthetic cause of Drop off at the end of stance phase

A
  • inadequate limitation of DF
  • too short keel of SACH-type foot
  • too far posterior toe break of a conventional foot
  • too far anterior socket (when related to the foot)
33
Q

Amputee cause of Drop off at the end of stance phase

A

-no specific medical causes

34
Q

Prosthetic cause for Long prosthetic step

A

-insufficient initial flexion in the socket when an irreducible residual limb flexion contractor is present

35
Q

Amputee cause for Long prosthetic step

A

-Flexion contracture un-accommodated prosthetically

36
Q

Prosthetic causes for Excessive trunk extension

A
  • improperly shaped posterior wall–> forward rot of pelvis to avoid full wt bearing on ischium
  • insufficient initial flexion build into the socket
37
Q

Amputee causes for Excessive trunk extension

A
  • hip flexor tightness
  • wk hip extensor–> lumbar substitution
  • wk abdominal mm
  • habit pattern
  • shoulders moving backward for better balance
