NIH Toolbox Motor - Grip Strength Test (NIH Toolbox Grip Strength Test Age 3+ v2.0)

Instrument Name: NIH Toolbox Motor - Grip Strength Test (NIH Toolbox Grip Strength Test Age 3+ v2.0)

Abbreviation: NIH Toolbox Grip Strength Test Age 3+ v2.0

Points for Consideration:

Requires use of a dynamometer

Description of Tool:

The NIH Toolbox Grip Strength Test Age 3+ v2.0 is a PerfO measuring the grip force of each hand (in pounds) using a dynamometer. Higher scores represent better strength in the upper extremeties.

Minimum Qualification Required by COA Administrator: MA or BA

Comment:

The NIH Toolbox 4 Grip Strength Test Age 3+ v2.0) is a specific test within the NIH Toolbox Locomotion
The NIH Toolbox Locomotion 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 strength: upper extremity

Population of Development: Age range (therapeutic indication):

3-85 years (All)

Pediatric Population(s) in which COA has been used:

Female Urogenital Diseases and Pregnancy Complications; Wounds and Injuries

COA type:

Number of Items 2 x 1 task

Mode of Administration:

Data Collection Mode:

Time for Completion: 3 minutes

Response Scales: Grip force of each hand (in pounds) using a dynamometer

Summary of Scoring:

Available Score:
Scores by items: Computed Score, Age-Corrected Standard Score (mean = 100, standard deviation (SD) = 15), Uncorrected Standard Score (mean = 100, SD = 15), Fully Corrected T-Scores (mean = 50, SD = 10), and National Percentile rank corresponding to Age-corrected Score, for dominant hand ; Computed Score for non dominant hand

Weighting:
No

Score Interpretation:
Lower score = Better strength in upper extremity
