Short Description of Instrument |
Pinch Strength is a measurement of strength generated by the thumb and forefinger, of one pound. The amount of muscle strength loss can be determined. |
Scoring |
Test should be performed at least three times. Record the result of each trial in the nearest pound or kilogram. Difference in scores should be within 6.6 lbs or 3 kg. If not, test should be repeated. Results are compared to published age and sex-specific norms. |
