• Assesses the capacity to perform ADL in children with SCI who use a manual wheelchair.
  • Tasks include:
    1) Donning a shirt
    2) Donning sweat pants
    3) Performance of even transfers
    4) Performance of uneven transfers (4 inch height difference)
    5) Wheelchair propulsion on even surfaces
    6) Wheelchair performance up a ramp.

Clinical Considerations

  • The TMT includes common ADL tasks for children with SCI
  • The objective scale (time in seconds) is useful to detect change
  • The client/clinician burden in completing the test is considerable

ICF Domain

Activity ▶ Mobility


  • Clinician-administered; performance-based measure
  • The individual completes each task 5 times, except for wheelchair skills which is only done 3 times. They are instructed to complete the task quickly but safely. If they are unsuccessful in completing the task, they can retry it and if they are not able to complete all 5 trials then no time is reported. If the individual requires more than 20 seconds to complete the task then it is considered “incomplete”.
  • Administration time is usually 60-90 minutes (time is required for instruction and rest times are given between trials).

Number of Items



  • An adjustable mat (dimensions not specified)
  • An 80 foot (24.3 m) corridor
  • A 45 foot (13.72 m) ramp with an 8 degree angle


  • Time (seconds) to complete each task is recorded
  • Based on the results of the reliability data it was decided to use the mean score of the fastest 3 trials for scoring each task.



Training Required

Does not require advanced training.

# of studies reporting psychometric properties: 1


  • More time required to complete each task indicates a lower capacity to perform ADL
  • No norms or meaningful cut-points have been established for the SCI population.

MCID: not established for SCI
SEM: not established for SCI
MDC: not established for SCI


  • Test-retest reliability of the TMT items ranges from Low to High (ICC = 0.30 – donning pants to ICC = 0.92 – wheelchair propulsion down the hall).
  • For videotaped sessions, intra-rater reliability ranges from Moderate to High (ICC = 0.73 – 0.95) as does inter-rater reliability (ICC = 0.71-0.95).

(Chafetz et al. 2004)


Groups with and without thoracolumbosacral orthoses have significantly different TMT scores for 5 of 6 items (all but ‘Propelling Up a Ramp’).

(Chafetz et al. 2004)


No values were reported for the responsiveness of the TMT for the SCI population.

Floor/Ceiling Effect

No values were reported for the presence of floor/ceiling effects in the TMT for the SCI population.
