The Aging Hand

The aim of this study was to describe changes in grip strength over a follow-up period of approximately 27 yr and to study the associations of rate of strength decline with weight change and chronic conditions. The data are from the Honolulu Heart Program, a prospective population-based study established in 1965. Participants at exam 1 were 8,006 men (ages 45-68 yr) who were of Japanese ancestry and living in Hawaii. At follow-up, 3,741 men (age range, 71-96 yr) participated. Those who died before the follow-up showed significantly lower grip-strength values at baseline than did the survivors. The average annualized strength change among the survivors was -1.0%. Steeper decline (>1.5%/yr) was associated with older age at baseline, greater weight decrease, and chronic conditions such as stroke, diabetes, arthritis, coronary heart disease, and chronic obstructive pulmonary disease. The risk factors for having very low hand-grip strength at follow-up, here termed grip-strength disability (

A standardised hand function test based on seven of the eight most common hand grips is reported. The test consists of 20 activities of daily living. The test procedure and the method of scoring are described as is our evaluation of the validity and reliability of the test. Fifty-nine tetraplegic patients were evaluated using the test before reconstructive surgery to their hands. The test score correlated well with the accepted international functional classification of the patient's arm (r = 0.76, p < 0.001). The mean test score in the arms of patients lacking sensation was significantly lower than in those with tactile gnosis (O:1-3 compared with OCu:1-3, p < 0.001).
