RESUMO
Vários testes de equilíbrio têm sido utilizados para identificar o controle postural e o risco de quedas em idosos. Entretanto, não se sabe quais testes refletem mais efetivamente a capacidade em manter o equilíbrio. O objetivo deste estudo foi comparar um conjunto de testes de campo de equilíbrio (TC) com os testes de posturografia em plataforma de força (PF) e verificar se esses testes são capazes de discriminar diferenças no equilíbrio entre jovens e idosos. Participaram do estudo 21 jovens (21,7 ± 2,0 anos) e 18 idosos (69,3 ± 7,0 anos) de ambos os gêneros. Os TC foram: escala de equilíbrio de Berg (BBS), escala de equilíbrio orientado pelo desempenho, (POMA), alcance funcional (AF) e levantar e caminhar cronometrado (TUGT). As variáveis analisadas na PF foram: amplitude de deslocamento nas direções anteroposterior (AMP-AP) e médio-lateral (AMP-ML) e trajetória do centro de pressão (TRAJ-CP). Os sujeitos foram avaliados em cinco condições durante 60s cada. Uma ANOVA one-way foi aplicada para determinar diferenças nos testes de equilíbrio entre grupos (jovens x idosos). Além disso, o teste de correlação de Spearman foi aplicado para identificar a associação entre os TC e PF. Os TC foram capazes de diferenciar jovens de idosos (p < 0,05). Os testes na PF também diferenciaram os grupos, exceto na AMP-AP em duas condições. As correlações indicaram que os testes BBS (r = - 0,43 ± 0,04) e TUGT (r = 0,45 ± 0,10) se correlacionaram com maior número de variáveis da PF (p < 0,05) e devem ser preferidos quando a avaliação do equilíbrio for determinada. Outros testes são questionados quanto à sua capacidade de determinar adequadamente o equilíbrio.
Several balance tests have been used to identify postural control and the risk of falls in the elderly. However, it is not known which tests better reflect effectively the ability to maintain balance. The objective of this study was to compare a number of field tests (FT) designed to determine balance with stabilometric tests using force platforms (FP) to determine whether these tests are able to discriminate differences in balance between young and older adults. Twenty-one young (21.7±2.0 years) and 18 older adults (69.3±7.0 years) of both genders volunteered to participate in the study. The field tests were: Berg Balance Scale (BBS), Performance Oriented Mobility Assessment (POMA), Functional Reach (FR) and Timed Up and Go Test (TUGT). The variables analyzed in the FP were: center of pressure displacement in the antero-posterior (AMP-AP) and medio-lateral direction (AMP-ML) and total sway of the center of pressure (TRAJ-CP). The subjects were evaluated in five conditions of 60s each. One-way ANOVA was applied to determine differences in balance tests between groups (young x elderly). In addition, the Spearman correlation test was used to identify the correlation between FT and FP. The FTs were able to discriminate young from elderly (p < 0.05). The FP tests also discriminated groups, except for AMP-AP in two experimental conditions. The correlation coefficients indicated that the tests BBS (r =- 0:43 ± 0.04) and TUGT (r = 0.45 ± 0.10) showed the largest correlation with the FP tests (p < 0.05). Thus, these field tests should be preferred among the other balance tests. The results of the other tests are questionable since they seemed unable to discriminate the balance performance between young and elderly subjects.
RESUMO
@#ObjectiveTo study the effect of Tetrax balance test and exercise on the balance function of stroke patients with hemiplegia. Methods50 stroke patients with hemiplegia and with disorder of balance function were divided into treatment group (25 cases) and control group (25 cases). The patients in both groups received regularly rehabilitation train and medical therapy. The treatment group was given balance train and motor function train responded to the analysis of the Tetrax balance assessment as well. They were evaluated with Berg balance scale, motor function of lower extreme in Fugl-Meyer Assessment (FMA) and activities of daily living (ADL) before and 4 weeks, 8 weeks, 12 weeks after treatment respectively. ResultsThere was no difference in balance function and motor function of lower extreme and ADL between treatment group and control group before treatment (P>0.05), but 4 week, 8 week, 12 week after treatment, there were significant improvement for balance function and motor function of lower extreme in both groups (P<0.01), and the treatment group improved more significantly than those of control group (P<0.05).ConclusionTexrax balance assessment can help understand the obstacle in balance function and formulate more suitable rehabilitation treatment.
RESUMO
OBJECTIVE: To investigate the effect and the correlation of characteristics of joint motion of lower extremity according to aging on balance in elderly. METHOD: There were thirty nine healthy elderly subjects aged 60 and older. The subjects were divided into 3 groups by their age. Each group was measured with joint motion of bilateral lower extremities by goniometer. The subjects were evaluated with clinical balance tests [(Berg balance scale (BBS), Functional reach test (FRT), Tinetti's performance oriented mobility assessment (POMA), and one leg standing (OLS)]. RESULTS: The flexibilities of lower extremities were decreased according to the increase in age. The balance ability was also decreased according to the increase in age by tested clinical balance scores. The flexibility of the ankle joints showed the strongest correlation with clinical balance scores (BBS, FRT, POMA and OLS) according to the increase in age, and the flexibility of hip joints also correlated with clinical balance scores (POMA and OLS). CONCLUSION: Among clinically validated balance tests, the decline of balance performance related with aging. Correlation exists between ankle ROM and balance in healthy elderly people. Additional research is needed to add the ankle ROM to reflect the excise for balance tests and balance ability.
