“…Sensation deteriorates with age, for example, the distance of two-point discrimination on the index finger tip becomes wider with increasing age [16]. Although sensory input seems essential for small object manipulation, research has found that impairments in tactile sensibility do not adversely affect manual tasks in older adults [37].…”

“…Force control Aging and UE function 4 may be as important as grip strength to older adults because most daily objects require the correct amount of force to maneuver; not maximum force. Moreover, aging has an adverse effect on steadiness [16] with older adults having less control of force output. Steadiness is defined as the ability to exert a constant submaximal force, and it is more strongly associated with fine motor coordination and precision than is grip strength [17].…”

“…Reduced cutaneous sensation has also been correlated with poor hand function (Dellon et al 1997;Melchior et al 2007), but the relationship between higher cutaneous thresholds at the fingertips and impaired motor performances are inconsistent (Cole et al 1998;Ranganathan et al 2001;Aoki and Fukuoka 2010;Murata et al 2010). It has also been suggested that work-related expertise in fine dexterous manipulation does not attenuate age-related changes in cutaneous sensation at the fingertip (Reuter et al 2012).…”

Cutaneous sensation deteriorates with age. It is not known if this change is consistent over the entire hand or if sensation is affected by changes in skin mechanics. Cutaneous perceptual thresholds were tested at eight sites in the glabrous skin and two in the hairy skin of both hands in 70 subjects (20-88 years), five male and five female per decade, using calibrated von Frey filaments, two-point discrimination, and texture discrimination. Venous occlusion at the wrist (40±10 mmHg) and moisturizer were used to alter skin mechanics. Cutaneous thresholds increased significantly with age (p<0.001); von Frey thresholds were 0.04 g [0.02-0.07] (median and interquartile range) in the 20s and 0.16 g [0.04-0.4] in the 80s, with differences between hands for older females (p00.044) but not males. The pattern of changes in cutaneous sensation varied according to the site tested with smaller changes on the fingers compared to the palm. Two-point discrimination deteriorated with age (p00.046), but with no interaction between sex, handedness, or changes in skin mechanics. There were no significant differences for texture discrimination. Changes in skin mechanics improved cutaneous thresholds in the oldest males after moisturizing (p00.001) but not otherwise. These results emphasize the complex pattern of age-related deterioration in cutaneous sensation with differences between sexes, the hands, sites on the hand, and the mode of testing. As the index fingertip is not a sensitive indicator of sensory decline, the minimum assessment of age-related changes in cutaneous sensation should include both hands, and sites on the palm.

“…Physical fitness (neuromuscular function) generally decreases with age, and individual differences are large in elderly groups (Bemben et al, 1991). Ranganathan et al (2001) examined effects of aging on hand function, and reported that, compared with younger subjects, elderly subjects have weaker handgrip and maximum pinch force, and decreased ability to maintain steady submaximal pinch force. They reported that the decrease in the ability to maintain steady submaximal pinch force is more pronounced in females than males.…”

This study examined age and sex differences of controlled force exertion in 207 males and 249 females aged 15 to 86 years. The subjects matched the submaximal grip strength of their dominant hand to changing demand values, appearing as a sinusoidal waveform on the display of a personal computer. The total difference (%) between the demand value and the grip exertion value for 25 sec was used as an evaluation parameter. Significant linear regressions were identified, but there was no significant difference in the rate of increase of both sexes. Analysis of variance showed insignificant differences among the means of both sexes, except for those of the 20-24yr-old group, and the differences between means of subjects greater than 50 years of age and 20 years of age increased in both sexes. Individual differences were almost the same in both sexes. The errors in controlled force exertion did not show a significant sex difference and tended to increase with age in both sexes. However, their rates of increase were significant only after 50 years of age.

Effects of Aging on Hand Function

Abstract: Aging has a degenerative effect on hand function, including declines in hand and finger strength and ability to control submaximal pinch force and maintain a steady precision pinch posture, manual speed, and hand sensation.
