“…Physical activity has been reported to modulate the functional state of the muscle and therefore influence proprioception 8 . Franco and Rodacki 12 found that differences in proprioception between young and elderly subjects were present only when active young subjects were compared to sedentary elderly subjects. Tsang and Hui-Chan 13 also identified the influence of physical conditioning on the ability to identify segment postures around the knee joint while comparing active and sedentary elderly subjects.…”

“…Therefore, positions that required wide ranges may have imposed a greater distention of the surrounding tissues and facilitated afferent sensory feedback. Thus, it may have produced a greater sensory stimulus that resulted in a small joint repositioning error 12 . This may be true specifically for the ankle joint, where narrow ranges tend to be near the maximum joint range of motion.…”

Background: Changes in the proprioceptive system are associated with aging. Proprioception is important to maintaining and/or recovering balance and to reducing the risk of falls. Objective: To compare the performance of young and active elderly adults in three proprioceptive tests. Method: Twenty-one active elderly participants (66.9±5.5 years) and 21 healthy young participants (24.6±3.9 years) were evaluated in the following tests: perception of position of the ankle and hip joints, perceived force level of the ankle joint, and two-point discrimination of the sole of the foot. Results: No differences (p>0.05) were found between groups for the joint position and perceived force level. On the other hand, the elderly participants showed lower sensitivity in the two-point discrimination (higher threshold) when compared to the young participants (p < 0.01). Conclusion: Except for the cutaneous plantar sensitivity, the active elderly participants had maintained proprioception. Their physical activity status may explain similarities between groups for the joint position sense and perceived force level, however it may not be sufficient to prevent sensory degeneration with aging.

“…Entre os principais problemas de saúde que afetam pessoas a partir dos sessenta anos de idade estão às quedas acidentais e suas implicações em morbidades, redução da funcionalidade, perda da independência e em casos extremos, a morte 2 . Vários fatores podem contribuir para as quedas entre idosos, todavia, os comprometimentos sensoriais decorrentes do envelhecimento têm sido apontados como um dos elementos centrais que podem resultar em déficits no controle postural e no equilíbrio [3][4][5] .…”

O comprometimento proprioceptivo decorrente do envelhecimento aumenta o risco de queda entre os idosos. Exercício físico pode atenuar o processo de declínio da sensação consciente da posição do corpo. Esta revisão sistemática teve como objetivo associar estudos que relacionam o exercício físico com a propriocepção em idosos. Realizou-se uma busca em três bases de dados eletrônicas (Pubmed/Mediline, Lilacs e Scopus) nos últimos 10 anos com a seguinte associação de descritores: (elderly OR aged) AND (proprioception OR position sense) AND exercise. A busca gerou 271 artigos e após aplicação de critérios de inclusão e exclusão, nove estudos foram selecionados para compor a revisão sistemática. Todos os artigos mostraram uma associação entre propriocepção e algum exercício físico. Tai chi chuan e Sessões de treinamento multifatorial foram as modalidades que apareceram com maior frequência entre os estudos (33 e 56% respectivamente), outras atividades compreenderam golfe, natação, corrida, fortalecimento muscular, flexibilidade, caminhada, exercícios de agilidade, equilíbrio, postura e de propriocepção. Tai chi chuan, séries multifatoriais, golfe e exercícios de propriocepção demonstraram ser as estratégias mais espressivas na melhoria da propriocepção entre os idosos.

“…Comparison of older and young adults reveals that aging is responsible for an increase in the ERT to reflex responses as well as for a reduction in proprioception, events that directly affect balance and postural control 12,13 . One study showed that women have a significantly longer ERT of the vastus medialis muscle than men during down stair climbing 14 .…”

Licence Creative Commom CC BY RBCDH Electromyographic reaction time in older female fallers and non-fallers after postural perturbationAbstract -The electromyographic reaction time (ERT) reflects the magnitude and speed with which muscles are activated to perform movements, to prevent injuries, or to position a joint. This parameter can be used to analyze postural control performance after an external perturbation and can be correlated with the possibility of falls in older adults. The objective of this study was to determine the ERT of the internal oblique, rectus femoris, vastus lateralis, tibialis anterior, multifidus, gluteus maximus, biceps femoris, and lateral gastrocnemius muscles to balance threats in older adults with and without a history of falls. Twenty-nine physically active and noninstitutionalized women aged 60 years or older were divided into two groups: fallers (n=13; 72.4 ± 8.0 years) and nonfallers (n=16; 67.8 ± 6.8 years). The ERT of the muscles tested did not differ significantly between groups following forward or backward perturbations. The results suggest that the activation of the muscles tested in response to forward or backward perturbations is not a determinant factor of falls
