Abstract
Study Design
Cross-sectional research design.
Introduction
Clinical practice continues to use normative data for grip and pinch measurements
that were established in 1985. There is no updated norms despite different hand usage
patterns in today's society.
Purpose of the Study
Measuring and comparing grip and pinch strengths with normative data is a valid method
to determine hand function. This research was implemented to compare the grip and
pinch measurements obtained from healthy millennials to the established norms and
to describe hand usage patterns for millennials.
Methods
Grip and lateral pinch measurements were obtained from a sample of 237 healthy millennials
(ages 20-34 years).
Results
Strength scores were statistically lower that older normative data in all millennial
grip strengths, with the exception of the women in the age group of 30-34 years. Specifically,
this statistically significant trend was observed in all male grip strengths, as well
as in women in the age group of 20-24 years (bilateral grip) and 25-29 years (right
grip). However, the lateral pinch data reflected was similar to the older norms with
variances of 0.5-1 kg.
Conclusion
Current data reflect statistically significant differences from the norms for all
male grip measurements, as well as for women in the age group of 20-24 years (bilateral
grip) and 25-29 years (right grip). No statistical significance was observed in the
independent-sample t tests for the lateral pinch in men of all age groups. Statistical significance was
noted for lateral pinch for female age groups for the left hand (20-24 years) and
for bilateral lateral pinches (30-34 years).
