Motor asymmetry reduction in older adults.
While cerebral lateralization has previously been well documented for many neurobehavioral functions, recent research has shown that as people age, formerly lateralized processes recruit more symmetric patterns of neural activity. Such findings provide the foundation for the model of hemispheric asymmetry reduction in older adults, or "HAROLD"[4]. Previous studies that have measured reaction ti...
متن کاملMotor Asymmetry Attenuation in Older Adults during Imagined Arm Movements
Laterality is an important feature of motor behavior. Several studies have shown that lateralization in right-handed young adults (i.e., right versus left arm superiority) emerges also during imagined actions, that is when an action is internally simulated without any motor output. Such information, however, is lacking for elderly people and it could be valuable to further comprehend the evolut...
متن کاملMotor Learning and Movement Performance: Older versus Younger Adults
Introduction: Motor skills play an important role during life span, and older adults need to learn or relearn these skills. The purpose of this study was to investigate how aging affects induction of improved movement performance by motor training. Methods: Serial Reaction Time Test (SRTT) was used to assess movement performance during 8 blocks of motor training. Participants were tested i...
متن کاملStudy of Explicit Knowledge Effects on Implicit Motor Learning in Older Adults
Objective: The motor skill performance and learning in older adults are of a great importance. The primary purpose of this study was to determine whether older adult’s explicit knowledge effect on implicit learning and motor performance and which are typical for rehabilitation and skills acquired in older adults. Materials & Methods: In this comparative study a serial reaction time task by u...
متن کاملCognitive Resources Necessary for Motor Control in Older Adults Are Reduced by Walking and Coordination Training
We examined if physical exercise interventions were effective to reduce cognitive brain resources recruited while performing motor control tasks in older adults. Forty-three older adults (63-79 years of age) participated in either a walking (n = 17) or a motor coordination (n = 15) intervention (1 year, 3 times per week) or were assigned to a control group (n = 11) doing relaxation and stretchi...
