Spinal Cord Injury:

(Musselman and Yang, 2013; n = 20 individuals with an incomplete SCI, > 7 months post-injury and able to ambulate at least 5 meters without manual assistance; participants free from cognitive or musculoskeletal impairments that might affect walking; mean age = 46.0(13.6) years; mean time post-injury = 5.4(8.8) years; sex = 6 females and 14 males)

• SEM for overall SCI-FAP Score = 34.5
• SEM for overall SCI-FAP Time = 41.2
• SEM for overall SCI-FAP Tasks: 
  • Carpet = 3.2 
  • Tug = 5.0 
  • Obstacles = 5.3 
  • Stairs = 7.5 
  • Carry = 4.5 
  • Step = 13.0 
  • Door = 3.7

Spinal Cord Injury:

(Musselman and Yang, 2013)

• MDC for overall SCI-FAP Score = 95.7 
• MDC for overall SCI-FAP Time = 114.2 
• MDC for overall SCI-FAP Tasks: 
  • Carpet = 9.0
  • Tug = 14.0 
  • Obstacles = 14.7 
  • Stairs = 20.6 
  • Carry = 12.4 
  • Step = 36.1 
  • Door = 10.2

Able-bodied Individuals:

(Musselman et al, 2011,  n = 60, mean age: 42.9(16.0) years; age range: 28-88 years)

• Floor 4.4 + 0.6s 
• Carpet 4.4+ 0.6s 
• Up & Go 9.1 + 1.2s 
• Obstacles 11.4 + 1.3s 
• Stairs 6.2 + 0.8s 
• Carry 4.4 + 0.5s 
• Step 3.7 + 0.5s 
• Ramp 6.2 +1.0s 
• Door 5.0 + 0.7s 

Mean times from the able-bodied data are used to normalize the task scores for the SCI-FAP. 

No difference in total SCI-FAP score across ages, except for Up & Go where individuals in their 20s performed significantly faster (p = 0.031) than those in their 50s.

Chronic Incomplete SCI:

(Musselman et al, 2011, n = 22; AIS C and D, paraplegia and tetraplegia; Test 1 and 2 completed 1-2 weeks apart) 

• Excellent test-retest reliability (ICC = 0.983 for total score) 
• Excellent test-retest reliability for all individual items

Chronic Incomplete SCI:

(Musselman et al, 2011, AIS C and D, paraplegia and tetraplegia)

• Intrarater Reliability ¨C Not established 
• Excellent Interrater Reliability (ICC= 1.000 for total score)
• Excellent Interrater Reliability for all individual items 

Chronic Incomplete SCI:

(Musselman et al, 2011, AIS C and D, paraplegia and tetraplegia) 

• Excellent Cronbach¡¯s alpha =0.95 

Of note, original test was developed with 9 tasks, but reduced to 7 as redundancy was found.

Discriminative Validity

Chronic Incomplete SCI:

(Musselman et al, 2011) 

• Scores of able-bodied individuals and those with SCI were compared via a t-test. Participants with SCI scored significantly higher on the SCI-FAP, P=.002, for the total score; 5 subjects with SCI demonstrated similar scores as able-bodied subjects. 

Convergent Validity

Chronic Incomplete SCI:

(Musselman et al, 2011) 

• Adequate ¨C total SCI-FAP with the 10MWT, and 6min walk test,(r = -0.59, -0.59 respectively). 
• Excellent ¨C total SCI-FAP with self selected WISCI II and maximum WISCI II (r = -0.68, -0.70 respectively). 
• Adequate to Excellent individual items:

Developed by SCI focus group and based on Modified Emory Functional Ambulation Profile (mEFAP); Confirmed by those who are experts in area of rehabilitation of incomplete spinal cord injury (n = 6)

Ceiling Effect

SCI:

(Musselman et al, 2011) 

• Adequate In individuals who are higher functioning and walked at normal speeds without devices, the SCI-FAP did not discriminate between SCI and able-bodied individuals, 15.63% of the sample (5/32). 
• Assistance ratings reduce the ceiling effect 

Floor Effect

SCI:

(Musselman et al, 2011)

• Individuals who are unable to walk, or unable to complete the walking tasks, will score the maximum on the measure of 2100.

SCI:

(Musselman and Yang, 2013)

• The SCI-FAP is responsive to change in walking function in individuals who walk slow speeds (i.e., < 0.5 m/s), but without manual assistance
• SRM for SCI-FAP Score = 0.59
• Future work with a greater sample size should focus on confirming responsiveness in individuals with lower walking function
