Background And Purpose:
Although strength diminishes with age, average values for grip strength have not been available heretofore for discrete strata after 75 years. The purpose of this meta-analysis was to provide average values for the left and right hands of men and women 75-79, 80-84, 85-89, and 90-99 years.
Methods:
Contributing to the analysis were 7 studies and 739 subjects with whom the Jamar dynamometer and standard procedures were employed.
Results:
Based on the analysis, average values for the left and right hands of men and women in each age stratum were derived.
Conclusions:
The derived values can serve as a standard of comparison for individual patients. An individual whose grip strength is below the lower limit of the confidence intervals of each stratum can be confidently considered to have less than average grip strength.
