Efeito da bandagem Dynamic Tape™ na atividade eletromiográfica do músculo glúteo médio e no desempenho funcional do membro inferior em mulheres saudáveis: estudo controlado e randomizado

Abstract

The Dynamic Tape ™ is a promising tool for neuro-musculoskeletal intervention of Australian origin, with similar principles as Kinesio taping®, but with superior mechanical properties. Few studies were dedicated to assess the effects of taping on the gluteus medius muscle function, and none of them used the taping Dynamic Tape ™. Thus, the aim of this study was to evaluate the effect of application of taping by Dynamic Tape ™ in electromyographic activity of the gluteus medius muscle and the functional performance of the lower limb in running tests and jump in healthy women. Fifty-two women between 18 and 30 years, active, were randomly allocated into three groups: Application Dynamic Tape ™ in the gluteus medius - banding group (GB, n = 17), application of Dynamic Tape ™ in placebo form the gluteus medius - placebo group (GP, n = 18) and without any intervention - control group (CG, n = 17). After physical assessment and verification of inclusion and exclusion criteria, the electromyographic evaluation of the gluteus medius muscle of the dominant limb at rest was performed maximal voluntary isometric contraction, squat, deck landing and jumping followed by maximum vertical jump platform. Subsequently, the functional performance in three tests were evaluated: shuttle run, triple hop test and six-meter timed hop test. Analysis of variance with repeated measures revealed no significant differences between groups and between the evaluation periods as the electromyographic activity of the gluteus medius muscle during rest (GBpré 2,03±1,01, GBpós 2,01±0,88; GCpré 1,55±0,96, GCpós 1,29±0,81; GPpré 1,78±0,92, GPpós 1,36±0,75) during the single leg squat task (GBpré 44,36±21,22, GBpós 40,28±16,18; GCpré 31,38±12,22, GCpós 34,74±19,90; GPpré 34,73±14,48, GPpós 29,43±11,01) the drop landing task (GBpré 27,98±12,95, GBpós 30,20±14,19; GCpré 22,62±8,68, GCpós 22,93±11,88; GPpré 21,56±6,87, GPpós 26,05±13,89) and during the jump landing + maximum vertical jump task (GBpré 43,54±18,40, GBpós 47,98±18,68; GCpré 39,23±16,99, GCpós 63,34±63,77; GPpré 79,64±177,49, GPpós 35,42±14,81). Similarly, there were no significant differences between groups and periods of assessment as to sutlle run tests (GBpré 9,99±0,83, GBpós 9,94±0,65; GCpré 9,78±0,73, GCpós 10,19±0,66; GPpré 9,76±0,82, GPpós 9,63±0,53), triple hop test (GBpré 2,71±0,37, GBpós 2,74±0,32; GCpré 2,75±0,51, GCpós 2,56±0,50; GPpré 2,76±0,47, GPpós 2,76±0,39) and six-meter timed hop test (GBpré 3,34±0,55, GBpós 3,26±0,57; GCpré 3,47±0,57, GCpós 3,70±0,54; GPpré 3,18±0,59, GPpós 3,22±0,56) .Therefore it follows that their use does not favor the electromyographic activity of the gluteus medius muscle and the performance of the lower limb in running tests and jump in healthy women.
