ABSTRACT
Kinesio taping (KT) has been proposed to modulate muscle tone. However no studies have systematically studied the efficacy of KTon this primary outcome measure. The objective of this study was to determine the effect of Kinesio taping (KT) applied over the gastrocnemius muscles on muscle tone, extensibility, electromyography (EMG) and strength. Nineteen healthy subjects were enrolled in a double-blind, placebo controlled crossover trial. KT and sham-tape were applied onto the gastrocnemius muscles of all subjects in two randomized sessions. Measurements before, at 10 min and 24 h after the intervention were taken. Outcome measurements included passive resistive torque to ankle dorsiflexion, dorsiflexion passive range of motion (PROM), surface Gastrocnemius Medialis (GM) EMG and maximal isometric voluntary force (MIVF). No significant differences were found between the sham-tape and KT groups for passive resistive torque, PROM nor maximal plantarflexion isometric voluntary force. A short-term increase of GM EMG activity was found in the KT group during the PROM mobilization, which was not maintained at 24 h following treatment. A short-term decrease in dorsiflexion force was produced 10 min after KT with respect to sham-tape application. These results demonstrate that the application of KT in the gastrocnemius muscles has no effect on healthy muscle tone, extensibility nor strength. However a short-term increase of GM EMG activity after KT treatment suggests the activation of central nervous system mechanisms, although without a therapeutic implication. Further studies with more appropriate designs are needed to clarify the physiological and therapeutic effects of this taping technique.

Objetivo: Analizar las diferencias en el recorrido del centro de presiones durante la realizaciónde 3 tests de equilibrio estáticos, en que se incluyen dos de las técnicas usadas en lostratamientos de la rehabilitación del esguince de tobillo.Material y método: Participaron voluntariamente 14 sujetos sanos, sin signo de bostezo articular(8 hombres y 6 mujeres), deportistas, con una media de edad de 19,9±3,8 años. Se midióel recorrido del centro de presiones durante tests de equilibrio monopodal sobre plataformade fuerzas (duración de 60 s), en tres condiciones: sobre superficie estable (plataforma), sobresuperficie viscoelástica, y aplicando estimulación eléctrica neuromuscular en el músculo tibialanterior.Resultados: La amplitud de desplazamiento del centro de presiones en el eje anteroposteriorfue mayor en el test con estimulación eléctrica neuromuscular que en el realizado sobre superficieestable (p < 0,01) y viscoelástica (p < 0,05). La posición media del centro de presiones sesituó más lateral (53,00±7,60mm) y anterior (128,40±10,70mm) en el test sobre superficieviscoelástica. Las mayores áreas barridas por el centro de presiones se obtuvieron en el testcon estimulación eléctrica neuromuscular (1.115,96±411,40mm2).Conclusiones: Con la electroestimulación se obtuvieron mayores amplitudes de desplazamientodel centro de presiones en el eje anteroposterior, una posición media más retrasada, y mayoresáreas barridas. Con la superficie viscoelástica se obtuvo un mayor recorrido y velocidad, y unaposición media del centro de presiones más lateral(AU)
Objective: To analyse the differences in the path of the centre of pressures during the performanceof 3 static balance tests, which included two of the techniques used in the rehabilitationof ankle sprain rehabilitation.Material and method: Fourteen healthy subjects, without ligament loosening in the ankle wererecruited for the study (8 male and 6 female) voluntary participated in this study, all of themphysically active, with a mean age of 19.9±3.8 years. The path of the centre of pressures wasmeasured during monopodal balance tests on a force platform (60 s last), in three different conditions:on stable surface (force platform), on a viscoelastic surface, and during the applicationof electrical stimulation on the tibialis anterior muscle.Results: The anterior-posterior path of the centre of pressures was greater in the test with electricalstimulation than in the tests on the stable surface (P < .01), and on the viscoelastic surface(P < .05).The mean position of the centre of pressures was more lateral (53.00±7.60mm) andmore posterior (128.40±10,70mm) in the test on the viscoelastic surface. The greatest excursionareas of the centre of pressures were found in the test with neuromuscular electricalstimulation (1115.96±411.40mm2).Conclusions: Greater anterior-posterior path length and excursion areas and a more posteriormean position of the centre of pressures were found in the neuromuscular electrical stimulationtest. We also found greater total excursions and velocity, and a more lateral mean position ofthe centre of pressures in the viscoelastic surface tests(AU)

ObjetivoAnalizar las diferencias intrasujeto entre una extremidad que presentó signo de bostezo articular en el tobillo, fruto de una lesión previa de esguince lateral, frente a una extremidad sin bostezo.Material y métodosTomaron parte en el estudio 14 sujetos voluntarios (6 mujeres y 8 hombres), deportistas, con una media de edad de 19,9±3,8 años. Se midió el rango de movimiento del tobillo de manera estática y pasiva, y el desplazamiento del centro de presiones durante un test de equilibrio monopodal sobre una plataforma de fuerzas (duración de 60s), en tres condiciones: sobre plataforma, sobre espuma y aplicando estimulación eléctrica neuromuscular en el músculo tibial anterior.ResultadosEl rango de desplazamiento del centro de presiones en el eje anteroposterior fue mayor en la extremidad con bostezo en el test sobre espuma (bostezo=60,9±14,3mm; sin bostezo=51,8±9,5mm) (p<0,05). La posición media del centro de presiones de la extremidad con bostezo se situó significativamente más medial en los 3 test (p<0,05) y más posterior en el test con espuma (p<0,01). En el test con electroestimulación, el recorrido total (bostezo=3.097,4±899,3mm; sin bostezo=3.329,3±996,6mm) y la velocidad media (bostezo=51,6±15,1mm/s; sin bostezo=55,1±17,0mm/s) fueron mayores en la extremidad sin bostezo (p<0,05).ConclusiónAl aumentar la dificultad de los test, aumentaron las diferencias entre ambas extremidades. La extremidad con bostezo modificó la posición del centro de presiones situándolo de forma más medial y posterior(AU)
ObjectiveThe purpose of this study was to analyse within subject differences in a number of static balance tests, performed during monopodal stance.Material and methodsThe tests were carried out comparing the ankle with a previous lateral ligament injury (with permanent ligament loosening) and the one without ligament loosening. Fourteen volunteer subjects were recruited for the study (6 women and 8 men), all of them physically active, with a mean age of 19.9±3.8 years. The measurements included the ankle range of motion (static and passive), and the path of the centre of pressures during a monopodal balance test on a force platform (60s last), in three different conditions: on the platform, on a foam pad and during the application of electrical stimulation on the tibialis anterior muscle. All the measurements and tests were applied on both legs, injured and uninjured.ResultsThe anterio-posterior path of the centre of pressures was greater in the previously injured limb in the test on the foam pad (injured=60.9±14.3mm; uninjured=51.8±9.5mm) (p<0.05). The mean position of the centre of pressures in the injured limb was more medial during the three tests (p<0.05) and more posterior in the test on the foam pad (p<0.01). In the test with electrical stimulation, the total path of the centre of pressures (injured=3097.4±899.3mm; uninjured=3329.3±996.6mm) and its average velocity (injured=51.6±15.1mm/s; uninjured=55.1±17.0mm/s) were significantly greater in the uninjured limb (p<0.05).ConclusionsWhen the tests became more challenging, the differences between injured and uninjured limbs were greater. The position of the injured extremity was more medial and posterior during the static tests(AU)

ObjetivoEl propósito del trabajo fue evaluar las diferentes características mecánicas ante esfuerzos de tracción en vendas usadas en la técnica del vendaje neuromuscular (Kinesio taping). Con ello, se pretende saber si los diferentes colores y marcas obedecen a características mecánicas diferentes. El propósito final es tener información que permita mejorar los protocolos de colocación, con mayor o menor tensión, para optimizar la acción (terapéutica o de otro tipo) del vendaje.MétodosSe cortaron especímenes de vendas de 30cm de largo de las marcas Cure Tape (negro, azul, rojo y piel), Sports Tex (negro, azul, rojo), Kinsiotape (azul y rojo) y Kinesiology Tape (azul y rojo). Se aplicaron cargas progresivas para explorar los diferentes esfuerzos a la tracción y las elongaciones relativas hasta llegar a la rotura de las vendas.ResultadosNo se encontraron los mismos comportamientos al comparar colores iguales en las diferentes marcas exploradas. La máxima elongación antes de romper varió entre el 77 y el 106% en las diferentes vendas testadas. La tensión máxima antes de romper varió entre 4,57 y 8,06MPa. Los módulos de Young promedio de las zonas lineales de las gráficas esfuerzo/deformación variaron entre 0,0526 y 0,0966MPa. Finalmente, los grosores de las diferentes vendas se situaron entre 0,44 y 0,55mm.ConclusionesEs recomendable no cambiar de marca ni color para una determinada aplicación del vendaje neuromuscular. De esta manera será más fácil conseguir una tensión de la venda cercana a la óptima mediante un determinado protocolo de estiramiento previo(AU)
ObjectiveThe purpose of the present study was to assess the mechanical characteristics of different types of tape utilized in neuromuscular taping (Kinesio Taping) during stress-strain tests, and find out whether the different brands and colours available in the market show different mechanical characteristics. A secondary purpose was to provide information related to the tape strain during the taping preparation, to optimize the taping effect.MethodsThirty-centimeter pieces of tape [Cure Tape (black, blue, red and pink), Sports Tex (black, blue and red), Kinsiotape (blue and red) and Kinesiology Tape (blue and red)] were cut and fixed. Then, progressive loads until the point of rupture were applied to calculate the stress-strain relationship for each tape.ConclusionsThe large variability found in the mechanical behaviour of the different tapes leads us to recommend the utilization of the same brand and colour for a given purpose. This will allow the physiotherapist to achieve an optimum tension level of the tape with a protocolized tape elongation(AU)
