“…Pesquisadores (Pei et al, 2008) verificaram melhoras nos níveis de coordenação motora em idosos submetidos a um programa de atividade física generalizada de intensidade moderada, porém estudos que comparam a coordenação motora de idosos que usam o computador são pouco encontrados. Lin et al (2014) compararam a força de preensão manual e a coordenação bimanual das mãos de jovens e idosos e observaram que o envelhecimento reduz a produção de força de preensão manual e aumenta o tempo de desempenho do controle de coordenação bimanual das duas mãos, deixando-os mais lentos que os jovens, o que pode levar a dificuldades de execução de atividades diárias que exigem ambas as mãos.…”

Resumo Este estudo buscou verificar os efeitos do uso do computador no desempenho cognitivo, estado emocional, qualidade de vida e habilidade motora manual de participantes de oficinas de informática. A amostra foi constituída por 114 idosos, divididos em grupo sem informática (GSI) com 58 idosos e grupo informática (GI) com 56 idosos. Os instrumentos utilizados foram: Exame Cognitivo de Addenbrooke Revisado (ACE-R), Escala de Depressão Geriátrica (GDS-15), Inventário de Ansiedade de Beck (BAI), qualidade de vida (WHOQOL-Bref), força de preensão manual (dinamômetro Saehan Corporation®) e motricidade fina (painel de habilidades manuais). Os resultados revelaram que o uso do computador contribuiu positivamente para a funcionalidade cognitiva do idoso, melhorando seu estado emocional, sua qualidade de vida e sua habilidade motora manual.

“…The effects on antiphase and complex phasing coordination have also been illustrated through the influence of force output demands. In addition to a reduction of handgrip maximum voluntary contraction (MVC), older adults take significantly longer to alternate grip forces between the two hands at multiple equal and unequal percentages of their MVC [22]. The above evidence illustrates an age-associated reduction in the stability of phasing accuracy with increased task demands, such as faster movement speeds and increased force demands.…”

Although evidence exists that changes in sensorimotor function occur with aging, changes in the bilateral coordination of the upper extremities is less understood. Here, we review the behavioral and neural evidence of declines in bilateral coordination as well as the implications these deficits have on function and physical rehabilitation. We begin with an introduction to the two major forms of bilateral coordination, symmetric and non-symmetric and their sub-groupings. After discussing the motor performance changes with age in symmetric tasks, we address age-related changes in motor lateralization that may affect the bilateral coordination of non-symmetric coordination. This is followed by a discussion of the contributions of cognitive, sensory, and cortical changes with age that influence and underlie bilateral motor performance. Finally, age-related changes in motor learning of bilateral movements are also considered. In general, most age related changes are found in complex symmetric movements but, surprisingly, there is a dearth of information about changes in the more challenging and ubiquitous non-symmetric bilateral movements. Future investigations should focus on broadening the understanding of age-related changes in complex, functionally relevant bilateral movements, such that the real-world implications of these changes may be derived.

“…One of the vital functions related to functional independence and activities of daily living (ADL) in the geriatric population is the ability to grasp and hold objects [ 15 ]. This ability requires a complex series of inputs from various body systems including the central nervous system (CNS) as well as the musculoskeletal system [ 8 , 16 ]. With advancing age, there are normal structural and functional changes that occur in the brain and within the musculoskeletal system, which may impact grasping functions.…”

BackgroundAs the population of adults aged 65 and above is rapidly growing, it is crucial to identify physical and cognitive limitations pertaining to daily living. Cognitive fatigue has shown to adversely impact neuromuscular function in younger adults, however its impact on neuromuscular fatigue, and associated brain function changes, in older adults is not well understood. The aim of the study was to examine the impact of cognitive fatigue on neuromuscular fatigue and associated prefrontal cortex (PFC) activation patterns in older women.MethodsEleven older (75.82 (7.4) years) females attended two sessions and performed intermittent handgrip exercises at 30 % maximum voluntary contraction (MVC) until voluntary exhaustion after a 60-min control (watching documentary) and 60-min cognitive fatigue (performing Stroop Color Word and 1-Back tests) condition. Dependent measures included endurance time, strength loss, PFC activity (measured using fNIRS), force fluctuations, muscle activity, cardiovascular responses, and perceived discomfort.ResultsParticipants perceived greater cognitive fatigue after the 60-min cognitive fatigue condition when compared to the control condition. While neuromuscular fatigue outcomes (i.e., endurance time, strength loss, perceived discomfort), force fluctuations, and muscle activity were similar across both the control and cognitive fatigue conditions, greater decrements in PFC activity during neuromuscular fatigue development after the cognitive fatigue condition were observed when compared to the control condition.ConclusionDespite similar neuromuscular outcomes, cognitive fatigue was associated with blunted PFC activation during the handgrip fatiguing exercise that may be indicative of neural adaptation with aging in an effort to maintain motor performance. Examining the relationship between cognitive fatigue and neuromuscular output by imaging other motor-related brain regions are needed to provide a better understanding of age-related compensatory adaptations to perform daily tasks that involve some levels of cognitive demand and physical exercise, especially when older adults experience them sequentially.
