NIH Toolbox for Assessment of Neurological and Behavioral Function - 2-minute Walk Test Endurance Age 3+ v2.0

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
