“…O aumento da força muscular é um dos objetivos principais na reabilitação de idosos, já que a diminuição dessa é responsável por uma série de limitações funcionais que podem leválos a condições de incapacidade. A avaliação da FM é extremamente importante no processo de tomada de decisão na prática da Fisioterapia 7,8 , sendo o dinamômetro isocinético o instrumento mais preciso para essa tarefa 9 .…”

Introdução: A força muscular diminui nos idosos portadores de osteoartrite de joelho. Objetivo: Avaliar os efeitos da fisioterapia convencional (FC) e da wiiterapia na força muscular de idosas com osteoartrite (OA) de joelho e comparar os resultados pré- e pós-intervenção. Métodos: Realizou-se estudo longitudinal, intervencionista, envolvendo 71 idosas (GI=33 (FC) e GII=38 (wiiterapia)), ≥60 anos, que responderam um questionário, sendo realizadas avaliação isocinética nas velocidades de 120, 180 e 240o/s e 20 sessões de fisioterapia. A intervenção constou de exercícios de equilíbrio, propriocepção, alongamento, fortalecimento. Resultados: Os músculos flexores são mais fracos no FC, e os extensores mais fortes em ambos os grupos, e quanto maior a velocidade menor a força nos extensores. Apesar de a força ser maior no wiiterapia, o FC também apresentou aumento de força tanto em flexores quanto em extensores. Conclusão: Ambos os métodos foram eficazes intragrupos, mas ao comparar-se a FC com a wiiterapia, não se encontraram resultados estatisticamente significativos.

“…Three attempts were made, and the patient was instructed to exhale and inhale with maximum strength after a maximal inspiration and expiration, respectively (23). Isometric grip strength of the dominant hand was measured using a hand dynamometer (Jamar dynamometer, Patterson Medical ®), while the patient was sitting upright in a chair with his/her arm resting on the armrest (24). We carried out three tests, and the highest value was recorded.…”

Background Complications after esophagectomy result in higher morbidity and mortality, longer hospital stays and lower quality of life. Unfortunately, we have insufficient knowledge of which patients will tolerate the combination of strenuous oncological therapy and major surgery. This study was designed to evaluate whether additional physical tests, apart from standard preoperative workups, could help identify high-risk patients regarding esophageal cancer surgery.Methods A total of 88 patients due to undergo esophagectomy for esophageal cancer were enrolled. In addition to the mandatory physical examinations, seven additional physical therapy tests were carried out within 10 days prior to surgery. CT scans were examined by an experienced radiologist to determine whether patients suffered from sarcopenia. Perioperative data and times of death were gathered from a national register. The primary outcome was the presence of any severe postoperative complication, classified as Clavien-Dindo ≥3, with specific complications as secondary outcomes, and associations between preoperative test performance and complications were examined.Results Patients with severe complications had preoperatively performed significantly worse on peak expiratory flow tests (p = 0.013). Patients suffering from anastomotic leakage had shown significantly worse performance on cardiopulmonary exercise testing, whereas the results from shoulder abduction tests were significantly lower in patients who later suffered from pneumonia (p = 0.034 and p = 0.043, respectively).Conclusion More extensive preoperative physical examination tests could potentially aid in identifying patients with an increased risk of postoperative complications. Further studies are needed on the subject to corroborate these findings and evaluate their clinical use.

“…In younger adults, dynamic balance recovery following gait perturbations are partly dependent on large, rapid leg extensor moments [ 7 , 8 ]. With advanced age, adults experience sarcopenia [ 9 , 10 ] and decreased muscle strength [ 11 , 12 ], which would intuitively hinder balance recovery in older adults. Indeed, older adults with reduced maximal isometric leg press strength are more likely to fall [ 13 ].…”

The effects of plantarflexor weakness and reduced tendon stiffness with aging on gait stability

Falls among older adults are a costly public health concern. Such falls can be precipitated by balance disturbances, after which a recovery strategy requiring rapid, high force outputs is necessary. Sarcopenia among older adults likely diminishes their ability to produce the forces necessary to arrest gait instability. Age-related changes to tendon stiffness may also delay muscle stretch and afferent feedback and decrease force transmission, worsening fall outcomes. However, the association between muscle strength, tendon stiffness, and gait instability is not well established. Given the ankle’s proximity to the onset of many walking balance disturbances, we examined the relation between both plantarflexor strength and Achilles tendon stiffness with walking-related instability during perturbed gait in older and younger adults–the latter quantified herein using margins of stability and whole-body angular momentum including the application of treadmill-induced slip perturbations. Older and younger adults did not differ in plantarflexor strength, but Achilles tendon stiffness was lower in older adults. Among older adults, plantarflexor weakness associated with greater whole-body angular momentum following treadmill-induced slip perturbations. Weaker older adults also appeared to walk and recover from treadmill-induced slip perturbations with more caution. This study highlights the role of plantarflexor strength and Achilles tendon stiffness in regulating lateral gait stability in older adults, which may be targets for training protocols seeking to minimize fall risk and injury severity.
