OBJECTIVES: The purpose of this study was to quantify age‐induced changes in handgrip and finger‐pinch strength, ability to maintain a steady submaximal finger pinch force and pinch posture, speed in relocating small objects with finger grip, and ability to discriminate two identical mechanical stimuli applied to the finger tip. 

The effects of strength training on finger strength and hand dexterity in healthy elderly individuals.

TLDR
The data suggest that strength training can also improve the hand function of less healthy elderly subjects and lead to changes in finger interaction and in performance of accurate force production tasks.

Effect of wrist position on grip force sense in healthy adults

TLDR
It is revealed that the absolute error, constant error, and MVIC decreased as the wrist joint angle deviated from the neutral position, in contrast to most previous studies.

TLDR
The hypothesis that hand-muscle function correlates with functional dependency in the elderly is supported, as Dreiser and Duruöz hand function indices were the best to correlate with ADL and quality of life.

Effects of an eight-week hand exercise program on older women with osteoarthritis

TLDR
Thissis (M.Ed.)--Wichita State University, College of Education, Dept. of Kinesiology and Sport Studies, examines the role of sport and exercise in the development of post-secondary education.

Examination of Older Females' Grip Characteristics

TLDR
Differences in grip characteristics measured in this study may improve the understanding of the loss of function in older adults' hands more than the decline in grip strength alone.

Finger tapping ability in healthy elderly and young adults.

TLDR
The decline of finger tapping ability in elderly adults seems to be less affected by their maximum force production capacities of the fingers as well as tactile sensitivities at the tips of the hands.

Impact of Exercise Frequency on Hand Strength of the Elderly

TLDR
For the most part, results indicated no significant difference between the hand-strengthening protocols when measuring hand strength over an 8-week period.

The aging hand.

TLDR
A review of anatomical and physiological changes in the aging hand is presented and the age-related changes in prehension patterns and hand dexterity in the elderly population are considered.

Associations among strength, steadiness, and hand function across the adult life span.

TLDR
The relation between measures of steadiness and hand function suggests that the physiological mechanisms responsible for differences in steadiness also contribute to differences in the performance of fine motor tasks with the hand.

Skilled finger movement exercise improves hand function.

TLDR
Skilled finger movement training improves the ability to control submaximal pinch force, hand steadiness, and manual speed in elderly subjects; these improvements may be due to training-induced adaptations in the central and peripheral nervous systems.

TLDR
Hand function seemed to remain stable until age 65 years, after which it diminished slowly, and after age 75 years, age differences in performance were most apparent.

Changes in hand function in the aging adult as determined by the Jebsen Test of Hand Function.

TLDR
There were significant positive correlations between age and time needed to complete the various subtests, and analyses of variance revealed significant differences between subjects in their 80s and those in their 60s and 70s.

Reduced control of motor output in a human hand muscle of elderly subjects during submaximal contractions.

TLDR
The data indicated that age had an effect on the variation of force about submaximal target forces, and that these force variations, when calculated relative to the target force, were greater at lower force levels in the elderly subjects.

The weakness of old age is not due to failure of muscle activation.

TLDR
It was found that both young and elderly subjects could fully activate their muscles and the muscle weakness of old age does not appear to be due to reduced activation and must be caused by another mechanism, possibly biochemical in nature.

Techniques to evaluate elderly human muscle function: a physiological basis.

TLDR
This review presents the practice and theory underlying the scientific measurement of elderly human muscle function, bridging the gap between the practical issues of measurement and the physiological significance of such measurements.

Maximal voluntary isometric force production characteristics of six muscle groups in women aged 25 to 74 years

TLDR
Since the magnitude of maximal force decreases with age, and because these characteristics can not be entirely explained by age‐related decrements in fat‐free mass, it appears that the quality in addition to the quantity of senescent muscle tissue may be compromised.

TLDR
In general healthy 70-year-old women showed a slighter decrease in function than men and a slight correlation was found between strength in elbow extension and static knee extension at 90 degrees knee angle in 70- year-old healthy subjects.

TLDR
The results suggest that the one set of norms given by Jebsen for 60 years and less for each sex, should be replaced by 5 or more, even though the differences were quite small when standard deviations were considered.

Tactile impairments cannot explain the effect of age on a grasp and lift task

TLDR
A similar relative slowing for the two groups fails to support the hypothesis that old adults’ ability to grip and lift the object was limited by changes in the availability or use of tactile information.
