Overview
Instrument Name: NIH Toolbox for Assessment of Neurological and Behavioral Function - 2-minute Walk Test Endurance Age 3+ v2.0
Abbreviation: NIH Toolbox 2MWT Age 3+ v2.0
Points for Consideration:
Appears beneficial but No data on diagnostic populations
Description of Tool:
The NIH Toolbox 2MWT Age 3+, v2.0 is a PerfO which measures the total distance walked in 2 minutes on a 50-ft course. Higher scores represent better endurance.
Minimum Qualification Required by COA Administrator: MA or BA
Comment:
The NIH Toolbox 2MWT Age 3+ v2.0 is a specific test within the NIH Toolbox Endurance
The NIH Toolbox Endurance is a subdomain within the NIH Toolbox Motor Battery
Year: 2013
Objective of Development:
To measure motor function across the age span from 3 to 85 years, with a focus on endurance
Population of Development: Age range (therapeutic indication):
3-85 years (All)
Pediatric Population(s) in which COA has been used:
Wounds and Injuries
COA type:
Number of Items 1 task
Mode of Administration:
Data Collection Mode:
Time for Completion: 2 minutes
Response Scales: Distance (meters)
Summary of Scoring:
Available Score:
Score by items: Raw score; Age-Corrected Standard Score (mean = 100, SD = 15); Uncorrected Standard Score (mean = 100, SD = 15); Fully Corrected T-Scores (mean = 100, SD = 15); National Percentile Rank
Weighting:
No
Score Interpretation:
Higher score =Better endurance
