Hand Dominance and Grip Strength of Older Asian Adults

Abstract

Hand dominance in a group of Asian adults 60 to 89 years old was examined. Participants were independently living in the community; free of pain, injury, and disease of the upper limbs; and had no restrictions on use of upper extremities in daily activities. The grip strengths of both hands were measured with a Jamar hand dynamometer. Analysis showed that being male, of younger age, and using the dominant hand were significantly associated with stronger grip than being female, of older age, and using the nondominant hand. The dominant to nondominant grip ratio varies from 1.05 to 1.10 across age-sex subgroups.

The relationship between heart rate as an indicator of work hardness and results of dynamometry

“…[12] In the Wang study pinch force in the men were more than women. [13] The results of this study is consistent with this study. In the present study the relationship between age and with the hand, pinch and back-leg-chest test based on Pearson correlation coefficient is significant.…”

“…[12] In Wang's study the non-dominant hand grip strength were lower than dominant hand, also grip power in men was more than women. [13] Hassani and his colleague report that the right and left hands of men were upper than women. [14] Brent and et al show that Hand-held dynamometry HHD has the potential to be a reliable tool for strength measurements in healthy, strong subjects; however, there are noteworthy limitations with movements where subjects can overpower the testers.…”

Long‐term functional donor site morbidity after ulnar forearm flap harvest

“…11,23 The high percentage of overall reduced grip strength measured in our series in both hands, especially in female patients, may be explained by the age group of the patients in our study because the standard values are stated for healthy adults and reduction of grip strength with increasing age is physiologic. [24][25][26] When evaluating the qualities of the reactive sensitivities we found reduced feeling of pain within the donor limb in about one fourth of the skin-grafted regions. This also agrees with the results of other follow-up studies for the radial as well as the ulnar forearm flap.…”

Work‐relief ratios and imbalances of load application in sport climbing: Another link to overuse‐induced injuries?

“…However, the last assumption needs to be proven. Although we did not collect dynamometric strength parameters, the 10% rule may contribute to this finding: grip strength of the dominant hand is considered to be approximately 10% higher compared with the nondominant hand (Petersen et al, 1989;Incel et al, 2002;Wang, 2010), but predominantly in the general population. In part, similar findings were reported and summarized in Giles et al (2006) regarding climbers.…”
