Short roundtable RBCM: treinamento funcional / Short Roundtable RBCM: Functional Training

O objetivo do estudo foi explorar informações gerais sobre treinamento funcional (TF), abrangendo conceito, características, ferramentas, controle de variáveis e carga, estado atual e perspectivas futuras. Foram convidados 13 autores com histórico de publicações nacionais sobre TF para responder 5 questões. Três aceitaram o convite. Concluiu-se que o TF é aquele que objetiva o aprimoramento equilibrado das capacidades biomotoras no intuito de garantir eficiência e segurança para o desempenho das atividades cotidianas. As características do TF se assemelham às funções cotidianas, sendo integrado, assimétrico, acíclico e multiplanar, no qual comportamento motor e equilíbrio entre capacidades biomotoras se destacam. Controle e progressão de cargas ainda carecem de evidências, sugerindo-se o uso de percepção de esforço, bem como as recomendações da literatura sobre heterocronismo da recuperação. A instabilidade apresenta vantagens como maior exigência neuromuscular para controle postural e de movimento, mostrando-se eficiente em aprimorar equilíbrio e desempenho funcional. Sua desvantagem é o prejuízo sobre o desempenho agudo de força, potência e velocidade. A ciência atual em TF tem explorado seus efeitos sobre ajustes morfofuncionais. Investigações futuras devem explorar o controle das variáveis, para minimizar a concorrência entre capacidades biomotoras distintas, bem como entender a eficácia do TF sobre a ótica da neurociência.(AU)

The aim of the study was to explore general information about functional training (FT), covering concept, features, devices, control of variables and load, current state and future prospects. Thirteen authors with a history of national publications on TF were invited to answer 5 questions. Three accepted the invitation. It was concluded the TF aims the balanced improvement of biomotor capabilities in order to ensure efficiency and security for the daily activities performance. The characteristics of TF are similar to daily activities being integrated, asymmetric, acyclic and multiplanar, in which motor behavior and balance between biomotor capabilities stand out. Control and progression of loads still lack evidence suggesting the use of rated perceived exertion as well as literature recommendations on recovery heterocronism. Instability has advantages such as increased neuromuscular requirement for postural control and movement, being efficient in improving balance and functional performance. Its disadvantage is the acute decrease on strength, power and speed movement. The current science of TF has explored its effects on morphological and functional variables. Future research should explore the control of variables to minimize of competition between different biomotor skills as well as understand the effectiveness of TF on the neuroscience perspective.(AU)

The Efficacy of Core Strengthening on the Trunk Balance in Patients with Subacute Stroke

OBJECTIVE: To investigate the efficacy of core strengthening on trunk balance in patients with subacute stroke. METHOD: Fifty-nine subacute hemiparetic stroke in-patients participated in this study. All patients were randomly assigned to one of two groups: the control group and the experimental group. Both groups received the same conventional physical therapies for 4 weeks. The experimental group received an additional core strengthening program (CSP). Korean mini-mental state examination (K-MMSE) and Korean Modified Barthel Index (K-MBI) were performed on admission. CSP was performed for 30 minutes a day, 3 days per week for 4 weeks. We selected nine exercises available for stroke patients, and divided them as three steps according to the degree of difficulty. Because of the muscle weakness in stroke patients, a physical therapist often helped them during exercise. Outcome measurement included trunk control test (TCT), trunk impairment scale (TIS), and Berg balance scale (BBS) and we compared both groups before and after the period of training. RESULTS: There were no significant differences in baseline general characteristics and initial values between the two groups. After rehabilitation therapy, both groups showed significant improvements in BBS, TIS, and TCT (p<0.05). Following 4 weeks of therapy, changes of BBS, TIS score in the experimental group were significantly higher than those of the control group (p<0.05). However, the change of TCT score was not significantly different. CONCLUSION: Analysis of different clinical parameters showed that better outcomes in BBS, TIS scores were achieved from CSP. This study suggests that CSP conducted for 4 weeks may be beneficial as a therapeutic technique for use in improvement of trunk balance in patients with subacute hemiparetic stroke.
