“…Lower-extremity strength of the hip and knee is a significant predictor of the ability to perform these activities [1,[12][13]. In a study examining the influence of hip and knee strength and hip power, Bean et al found that isometric hip extensor strength was the strongest predictor of the amount of time that functionally impaired adults would require to complete five chair rises [12].…”

Abstract-We compared differences in isometric strength between older adults who have undergone elective unilateral total hip arthroplasty (THA) and completed rehabilitation with a population of community-dwelling older adults who have not had THA. The study was a cross-sectional design, and 22 unilateral THA subjects and 38 community-dwelling older adults participated. THA subjects received on average 13 outpatient or home-based physical therapy sessions before evaluation. THA subjects were evaluated 4 to 5 months postsurgery. We assessed isometric muscle strength by measuring peak hip torque per body weight with a robotic dynamometer during abduction, flexion, and extension. No significant performance differences were observed between operated and nonoperated hips of THA subjects. THA subject operated and nonoperated hips generated significantly less peak torque per body weight during flexion (p = 0.03) compared with community-dwelling older adult hips (THA subject operated hips = 6.96 ft-lb/lb, THA subject nonoperated hips = 8.26 ft-lb/lb, communitydwelling older adult hips = 11.56 ft-lb/lb). No significant differences were observed between THA subjects and community-dwelling older adults during hip extension (p = 0.55) or abduction (p = 0.17). At 4 to 5 months postsurgery, THA subjects were not at the same level of biomechanical performance as community-dwelling older adults. Significant strength deficits were found in THA subject operated versus nonoperated hips during isometric flexion. Additional or modified physical therapy that targets the hip flexors is recommended after THA.

“…TUG tasks demands one to interact with the surrounding environment, as well as have integrative upper/lower-limb movement with a coordinated cognitive process. In general, when patients perform the TUG test, they need to have the neuromuscular-skeletal components of agility, flexibility, balance, and strength [12,18,19]. This present study sought to investigate any relationship between the TUG performance time and CAL in chronic stroke survivors.…”

“…Subjects are concentrating on consecutive tasks in order to balance while performing sit-to stand, turning around and returning to the starting point [18]. To do this, they need to have the neural muscular skeletal components of strength, agility, flexibility, and balance [12,18,19]. There is complex relationship between the attentional demands to control motor performance and the performance in daily living.…”

Objective:The timed up and go (TUG) test is method used to determine the functional mobility of persons with stroke. Its reliability, validity, reaction rate, fall prediction, and psychological characteristics concerning ambulation ability have been validated. However, the relationship between TUG performance and community ambulation ability is unclear. The purpose of this study was to investigate whether the TUG performance time could indicate community ambulation levels (CAL) differentially in persons with chronic stroke. Design: Cross-sectional study. Methods: Eighty-seven stroke patients had participated in this study. Based on the self-reporting survey results on the difficulties experienced when walking outdoors, the subjects were divided into the independent community ambulation (ICA) group (n=35) and the dependent community ambulation group (n=52). Based on the area under the curve (AUC), the discrimination validity of the TUG performance time was calculated for classifying CAL. The Binomial Logistic Regression Model was utilized to produce the likelihood ratio of selected TUG cut-off values for the distinguishing of community ambulation ability. Results: The selected TUG cut-off values and the area under the curve were <14.87 seconds (AUC=0.871, 95% confidence interval=0.797-0.945), representing a mid-level accuracy. Concerning the likelihood ratio of the selected TUG cut-off value, it was found that the group with TUG performance times shorter than 14.87 seconds showed a 2.889 times higher probability of ICA than those with a TUG score of 14.87 seconds or longer (p<0.05). Conclusions:The TUG can be viewed as an assessment tool that is capable of classifying CAL.

“…The activities proposed by the TUG need strength, agility, and balance 23,24 . Thus, smaller values indicate better functional mobility, better balance, increased gait speed and, therefore, a minor risk of falling, as well as a possible greater independence in daily life activities.…”

Melhora do equilíbrio postural em mulheres idosas com o uso de informação sensorial adicional

RESUMO O processo natural do envelhecimento humano apresenta alterações morfológicas e fisiológicas, como alterações de equilíbrio e da marcha, aumentando o risco de cair. Alguns estudos investigaram a utilização da informação sensorial na melhora do equilíbrio corporal utilizando o toque suave em uma superfície rígida e estacionária, verificando uma redução significativa da oscilação corporal. Avaliou-se os efeitos da informação sensorial adicional durante a marcha em mulheres idosas. Foram avaliadas 30 mulheres com 60 anos ou mais. A adição da informação sensorial foi feita por uma bandagem infrapatelar. As participantes realizaram os testes propostos pelo Dynamic Gait Index (DGI), pelo Timed Up and Go (TUG) e pelo Teste de Caminhada de 10 Metros (TC10m), com e sem a bandagem infrapatelar. As comparações dos dados foram realizadas com o teste t pareado e o teste de Wilcoxon, com p≤0,05. Houve diferença significativa na comparação do TUG (sem bandagem: 10,13±2,1; com bandagem: 9,71±2,1, p=0,0007) e no DGI (sem bandagem: 20,65±2,1; com bandagem: 22,1±2,1, p=0,002). Não houve diferença significativa no uso da bandagem no TC10m. Os resultados mostraram que o uso da informação sensorial adicional gerada pela bandagem infrapatelar promoveu melhora da mobilidade funcional e do desempenho físico em mulheres idosas.

The Relative Importance of Strength and Balance in Chair Rise by Functionally Impaired Older Individuals

Abstract: Lower extremity strength and balance control both play a role in performance of chair rise; lower extremity strength is the stronger predictor of success for functionally impaired older adults.
