Outcome Measures for Individuals with LE Limb Loss

Question 1

Describe the amputee mobility predictor

Answer 1

• Ceiling effect with higher level mobility
• AMP scores >37 indicate K3 prosthetic & they are ready to perform activities beyond basic ambulation is they show proficient balance, postural stability sitting/standing, & can vary walking cadence

Question 2

Amputees with AMP scores of 32-47 have

Answer 2

• Adequate balance both static and lower level dynamic activities
• Better than average lower limb power
• Competent use of prosthesis

Question 3

Slide 7-8

Question 4

List he gait speeds for each K level

Answer 4

• K1 = 0.17 m/sec (0.15-0.19)
• K2 = 0.38 m/sec (0.25-0.54)
• K3 = 0.63 m/sec (0.50-0.71)
• K4 = 1.06 m/sec (0.95-1.18)

Question 5

Fall risk for transtibial amputation TUG

Answer 5

• TUG test of ≥19 sec
• Turn time of ≥3.7 sec
• Turn takes ≥6 steps

Question 6

Fall risk for transtiibial amputation four square step test

Answer 6

• FSST of ≥24 sec

Question 7

Describe the L test

Answer 7

• Modified TUG
• Incorporates 2 transfers & 4 turns of which at least 1 would be to the opposite side
• Total distance covered is 20m walk
• Walking path representing an “L” configuration requires turns to both the R/L
• Standard distance (3 x 7m)
• MCID = 4.5 sec

Question 8

Describe the berg balance scale/community dwelling individuals with lower limb amputation

Answer 8

• Slight ceiling effect
• May not be challenging enough to expose the balance deficits in community dwelling individuals with LLA

Question 9

Participants performed worse on the BBS if they were classified as any of the following:

Answer 9

• Having fear of falling*
• Using a mobility aid for daily ambulation*
• Having a unilateral transfemoral amputation as opposed to transtibial
• Having a dysvascular-related amputation
• Having experienced ≥2 falls in the previous 12 months, as opposed to ≤1

Question 10

Predictors of Prosthetic Use in Older Adults referred to SNF for Prosthetic Training

Answer 10

• Good cognition
• More distal amputation level
• Pre-operative functional independence

Question 11

Self report measures for amputees

Answer 11

• PLUS-M (prosthetic limb users survey of mobility
• CLASS (comprehensive lower limb amputee socket survey
• Houghton Scale
• Prosthetic Evaluation Questionnaire (PEQ)

Question 12

Outcome measures for amputees

Answer 12

• Amputee Mobility Predictor
• 6MWT
• FLAG (functional lower limb amputee gait assessment)
• Two Minute Walk Test
• TUG
• Four Square Step Test
• L-Test
• Berg Balance Scale
