Age-Related Reversal of Postural Adjustment Characteristics During Motor Imagery
Physical and imagined movements show similar behavioral constraints and neurophysiological activation patterns. An inhibition mechanism is thought to suppress overt movement during motor imagery, but it does not effectively suppress autonomic or postural adjustments. Inhibitory processes and postural stability both deteriorate with age. Thus, older people's balance is potentially vulnerable to ...
متن کاملIncomplete inhibition of central postural commands during manual motor imagery.
Imagined movements exhibit many of the behavioral and neurophysiological characteristics of executed actions. As a result, they are considered simulations of physical actions with an inhibition mechanism that suppresses overt movement. This inhibition is incomplete, as it does not block autonomic preparation, and it also does not effectively suppress postural adjustments planned in support of i...
متن کاملAge-Related Differences in Corticospinal Excitability during Observation and Motor Imagery of Balance Tasks
Postural control declines across adult lifespan. Non-physical balance training has been suggested as an alternative to improve postural control in frail/immobilized elderly people. Previous studies showed that this kind of training can improve balance control in young and older adults. However, it is unclear whether the brain of young and older adults is activated differently during mental simu...
متن کاملThe hemodynamic response characteristics underlying the age-related change of brain activation during motor execution
Introduction Brain areas are additionally activated in elderly subjects [1,2]. It was suggested that this additional recruitment of brain areas in elderly subjects was consistent with the compensation hypothesis and characterized neuroplasticity at the systems level in the aging brain, rather than dedifferentiation hypothesis [2]. On the other hand, age-related reduction of BOLD signal (hemodyn...
متن کاملRehearsal strategies during motor-sequence learning in old age: execution vs motor imagery.
Motor imagery and action-based rehearsal were compared during motor sequence-learning by young adults (M = 25 yr., SD = 3) and aged adults (M = 63 yr., SD = 7). General accuracy of aged adults was lower than that of young adults (F(1,28) = 7.37, p =.01) even though working-memory capacity was equivalent in the two groups. Motor imagery and rehearsal by action increased accuracy in both age grou...
