Age-Related Difficulty in Rhythmic Movement.

Age-related kinematic differences as influenced by task difficulty, target size, and movement amplitude.

Fifteen older adults (M = 68 years old) and 15 young adults (M = 23 years old) participated in a speed-accuracy task in which aiming movements were performed on a digitizing tablet to assess movement slowing and variability in older adults. Target-size and movement amplitude influences were analyzed separately to determine if they affected the performance of the young and older adults different...

Age-Related Changes in Bimanual Instrument Playing with Rhythmic Cueing

Deficits in bimanual coordination of older adults have been demonstrated to significantly limit their functioning in daily life. As a bimanual sensorimotor task, instrument playing has great potential for motor and cognitive training in advanced age. While the process of matching a person's repetitive movements to auditory rhythmic cueing during instrument playing was documented to involve moto...

Age-related changes in perception of movement in driving scenes.

PURPOSE Age-related changes in motion sensitivity have been found to relate to reductions in various indices of driving performance and safety. The aim of this study was to investigate the basis of this relationship in terms of determining which aspects of motion perception are most relevant to driving. METHODS Participants included 61 regular drivers (age range 22-87 years). Visual performan...

Age-related changes in maximal hip strength and movement speed.

BACKGROUND We quantified age-related decreases in the ability of female participants to generate whole leg movements about the hip. METHODS We measured maximum hip strength and hip velocity in 12 young and 12 older healthy women. Both capabilities could help fall prevention by contributing to fast leg movements. We also measured maximum velocities as a function of isotonic load. RESULTS You...
