Exploratory: Spinal Cord Injury (SCI) and SCI-Pediatric (age 5 and over)
|Short Description of Instrument||
Construct measured: Wheelchair Mobility
Generic vs. disease specific: Disease specific
Means of administration: Administered by a clinician
Intended respondent: Participant
# of items: 9
# of subscales and names of sub-scales: 3, tempo, technical skill, and physical capacity
Background: The test was developed to measure manual wheelchair mobility (skill and performance). It was developed for SCI.
There are 9 items, which cover 3 aspects of mobility:
1) Tempo (tasks = figure-of-8 shape and sprint)
2) Technical skill (tasks = crossing a doorstep, mounting a platform, and transferring)
3) Physical capacity (tasks = wheelchair propulsion and ascending slopes)
This is a performance-based measure intended to be administered by a clinician. During each of the following tasks, performance time, distance, or successful completion are recorded. There is a resting time of 2 minutes between each task.
Some psychometric testing has been conducted for the SCI population. Reliability: Intra-rater reliability for the total WC (ICC=0.98), for both individual tasks (ICC=0.71-0.99), and for record peak heart rate during tasks (ICC=0.68-0.96); Inter-rater reliability for the total WC (ICC=0.97), individual tasks (ICC=0.76-0.98), and record peak heart rate during tasks (ICC=0.82-0.99). Validity: The total ability score and performance time score significantly correlate to the FIM mobility subscale score, peak power output, and VO2 peak. Responsiveness: Standardized response means have been calculated between start of rehabilitation program and discharge: 0.6 for Ability score; 0.9 for Performance time score; and 0.8 for Physical strain score.
Appropriate for acute, subacute and chronic injury.
