Grip Strength / Effort Testing Calculator
$39.50
Subtests:
- Maximum Voluntary Effort
- Rapid Exchange Grip
Outcome Measures:
- Average (each rung)
- Standard Deviation
- Coefficient of Variation
- Cut-Points Over Coefficient of Variation
- Maximum Voluntary Effort (MVE)
- Rapid Exchange Grip (REG)
- MVE – REG
- Population Average and Standard Deviation
Special Features:
- All normative data values provided can be viewed and permanently modified/edited directly in the calculator.
- Ability to load raw data into calculator directly from spreadsheet.
- Alerted when cut-points are over coefficient of variation by highlighting them in green.
- Produces graph (directly on the form) plotting averages against population norms at all five rung positions, thus allowing user to conduct visual bell curve analysis.
- Produces a summary report in Excel with all raw data and outcome measures, up to 4 (re)tests in one form, and graphs comparing re-test results.
