Comparison of multisensory and strength training for postural control in the elderly
Objective: The objective of this study was to analyze the efficacy of multisensory versus muscle strengthening to improve postural control in healthy community-dwelling elderly. Participants: We performed a single-blinded study with 46 community-dwelling elderly allocated to strength (GS, n = 23; 70.18 +/- 4.8 years 22 women and 1 man) and multisensory exercises groups (GM, n = 23; 68.8 +/- 5.9 years; 22 women and 1 man) for 12 weeks. Methods: We performed isokinetic evaluations of muscle groups in the ankle and foot including dorsiflexors, plantar flexors, inversion, and eversion. The oscillation of the center of pressure was assessed with a force platform. Results: The GM group presented a reduction in the oscillation (66.8 +/- 273.4 cm(2) to 11.1 +/- 11.6 cm(2); P = 0.02), which was not observed in the GS group. The GM group showed better results for the peak torque and work than the GS group, but without statistical significance. Conclusion: Although the GM group presented better results, it is not possible to state that one exercise regimen proved more efficacious than the other in improving balance control
Uso de testes clĂnicos para verificação do controle postural em idosos saudĂĄveis submetidos a programas de exercĂcios fĂsicos
With aging, postural control diminishes, but the practice of physical exercises can improve this important function. Various tests can be used to measure these possible improvements. The objective of this study is to analyze the use of clinical tests of indirect measurements to verify the alterations in the postural control of healthy elderly submitted to physical exercise programs. The study's design is a randomized, simple-blind clinical test with the subjects' arms parallel. In the research there were 46 elderly divided randomly into two groups of exercises: multi-sensorial (MSG, n=23, 68.8±5.9 years) and strengthening (resistance training) (RTG, n=23, 70.18±4.8). Both groups performed 12 weeks (2 days/week, 50minutes/day) of exercises. To evaluate their postural control the following tests were utilized: Timed up and go (TUG), unipodal support test, battery of Guralnik tests, and the Berg functional balance scale. The MSG individuals showed significant improvement in the TUG tests and Guralnik battery of tests, and the RTG individuals did not show improvement in any of the tests. The improvement in the time of execution of the TUG test of the MSG group was 9.1±8.04 to 8.0±1.0 seconds after intervention, and it was statistically higher than the RTG group result. We believe the TUG test and the Guralnik battery of tests are good options to evaluate the postural control of the elderly submitted to the intervention programs. Although the TUG cannot have its time diminished indefinitely, it allows the verification, even within a normalcy time, of alterations brought on by physical exercises.O controle postural no envelhecimento diminui e a prĂĄtica de exercĂcios fĂsicos pode melhorar esta importante função. A fim de medir estas possĂveis melhoras, podem ser usados diversos testes. O objetivo deste estudo foi o de analisar o uso de testes clĂnicos de medidas indiretas para verificar as alteraçÔes sobre o controle postural de idosos saudĂĄveis submetidos a programas de exercĂcios fĂsicos. O desenho do estudo foi um ensaio clĂnico simples-cego e aleatorizado com braços paralelos. Participaram da pesquisa 46 idosos divididos aleatoriamente em dois grupos de exercĂcios: multissensoriais (GMS, n=23, 68,8±5,9 anos) e de fortalecimento (treino resistido) (GR, n=23, 70,18±4,8). Ambos os grupos realizaram 12 semanas (2dias/semana, 50m/dia) de exercĂcios. Para avaliação do controle postural foram utilizados os testes: Timed up and go (TUG), teste de apoio unipodal, bateria de testes de Guralnik e escala de equilĂbrio funcional de Berg. Os indivĂduos do GMS apresentaram melhora significativa nos testes TUG e bateria de testes de Guralnik e o GR nĂŁo apresentou melhora em nenhum dos testes. A melhora no tempo de execução do teste TUG do GMS que foi de 9,1±8,04 para 8,0±1,0 segundos apĂłs a intervenção, foi estatisticamente superior ao resultado do GR. Acreditamos que o teste TUG e a bateria de testes de Guralnik sĂŁo boas opçÔes para avaliar o controle postural de idosos submetidos a programas de intervenção. Embora o TUG nĂŁo possa ter seu tempo diminuĂdo indefinidamente, permite verificar atĂ© mesmo dentro de um tempo de normalidade, alteraçÔes promovidas por exercĂcios fĂsicos

The objective of this study was to compare the efficacy of multisensory versus strength exercises on these parameters. We performed a simple blinded randomized controlled trial with 46 community-dwelling elderly allocated to strength ([GST], N = 23, 70.2-years-old ± 4.8 years) or multisensory ([GMS], N = 23, 68.8-years-old ± 5.9 years) exercises twice a week for 12 weeks. Subjects were evaluated by blinded raters using the timed ‘up and go’ test (TUG), the Guralnik test battery, and a force platform. By the end of the treatment, the GMS group showed a significant improvement in TUG (9.1 ± 1.9 seconds (s) to 8.0 ± 1.0 s, P = 0.002); Guralnik test battery (10.6 ± 1.2 to 11.3 ± 0.8 P = 0.009); lateromedial (6.1 ± 11.7 cm to 3.1 ± 1.6 cm, P = 0.02) and anteroposterior displacement (4.7 ± 4.2 cm to 3.4 ± 1.0 cm, P = 0.03), which were not observed in the GST group. These results reproduce previous findings in the literature and mean that the stimulus to sensibility results in better achievements for the control of balance and dynamic activities. Multisensory exercises were shown to be more efficacious than strength exercises to improve functional mobility.Keywords: older adults, balance, functional mobility, exercisesCorrigendum for this paper has been publishe
