Critical decline in fine motor hand movements in human aging.

BACKGROUND: Slowing of motor movements in human aging is a well-known occurrence, but its biologic basis is poorly understood. Reliable quantitation may refine observations of this phenomenon to better aid research on this entity. METHODS: A panel equipped with timing sensors under computer control was used to measure upper extremity movement times in two groups of healthy individuals: adults younger than 60 years of age (n = 56; range, 18-58 years) and adults older than 60 years of age (n = 38; range, 61-94 years). RESULTS: Fine motor performance was better in the dominant hand (p = 0.0007) regardless of age. Adult and aged groups differed on two basic timing measures, which reflect coarse motor and fine motor performance (p < 0.0001). There were no gender differences on either measure. There was a strong effect of task difficulty with age on coarse motor (p < 0.01) and fine motor (p < 0.0001) measures. The fine motor measure of hand performance in healthy individuals correlated in a nonlinear fashion with age for more difficult tasks (r2 = 0.63) but showed a simple linear relation for less-demanding tasks (r2 = 0.5). CONCLUSION: This technique sensitively detects age-related motor performance decline in humans. There may be a critical period in late midlife when fine motor performance decline either begins or abruptly worsens.

Children's memory for pain.

Although there is a rich body of research on the development of children's memory for the details of personally experienced events, relatively little is known about age-related changes in the ability to remember pain. This gap in the literature is surprising, given that studies of children's memory for painful experiences are relevant to our basic understanding of cognitive development, pain perception, and--in some situations--patient management. This article examines what is known about children's memory for pain, given its inherent importance, working from the vantage point of the literature on the development of autobiographical memory. In doing so, the authors make use of an informal information-processing framework to organize their thoughts about the acquisition, retention, and distortion of information about painful experiences. Nonetheless, the authors recognize that this framework will no doubt need to be modified to take into account the complex memory representations--containing somatosensory, affective, and contextual information--that are established after exposure to painful stimulation. After the treatment of the literature, the authors discuss its implications for the clinical management of pain in pediatric settings.
