RESUMO

Abstract Introduction Kinesio tape (KT), although frequently used in sports, is still a matter of debate, and the results of studies that evaluated its effects on muscle strength (MS) in athletes are still inconclusive and contradictory. Objective To evaluate the effect of a progressive KT tension protocol on knee MS in runners over an eight-week intervention. Methods Clinical trial involving 49 runners of both sexes randomized into two groups: KT (KT with progressive tension protocol) and placebo (KT without tension). The MS of knee flexors and extensors was evaluated by isokinetic dynamometer (60º/s and 90º/s) at four moments: (1) without KT; (2) with KT and without tension; (3) without KT (after 8 weeks after of intervention); (4) with KT and with tension (after 8 weeks after of intervention). Inter- and intra-group comparisons were made. The significance level adopted was 95% (p < 0.05). Results There were no significant differences in MS between the groups at any of the evaluated moments. There was a statistically significant difference in MS (60º/s) in both groups (KT and placebo) when comparing moments 4 and 2 for knee flexors, and in the placebo group between moments 4 and 2 and moments 4 and 3 for knee extensors. Conclusion The progressive tension protocol of KT was not able to intervene in the SM gain of knee flexors and extensors of runners in inter and intragroup comparisons.


Resumo Introdução A Kinesio tape (KT), apesar de muito utilizada na prática esportiva, ainda é motivo de debate e os resultados de estudos que avaliaram seus efeitos na força muscular (FM) em atletas ainda são inconclusivos e contraditórios. Objetivo Avaliar o efeito de um protocolo de tensão progressiva KT na FM do joelho em corredores ao longo de uma intervenção de oito semanas. Métodos Ensaio clínico envolvendo 49 corredores de ambos os sexos randomizados em dois grupos: KT (KT com protocolo de tensão progressiva) e placebo (KT sem tensão). A FM dos flexores e extensores do joelho foi avaliada por dinamômetro isocinético (60º/s e 90º/s) em quatro momentos: (1) sem KT; (2) com KT e sem tensão; (3) sem KT (após 8 semanas); (4) com KT e com tensão (pós-protocolo 8 semanas). Comparações inter e intragrupos foram feitas. O nível de significância adotado foi de 95% (p < 0,05). Resultados Não houve diferenças signi-ficativas na FM entre os grupos em nenhum dos momentos avaliados. Houve diferença estatisticamente significante na FM (60º/s) em ambos os grupos (KT e placebo, quando comparados os momentos 4 e 2 para flexores de joelho, e no grupo placebo entre os momentos 4 e 2 e os momentos 4 e 3 para extensores de joelho. Conclusão O protocolo de tensão progressiva de KT não foi capaz de intervir no ganho de FM de flexores e extensores de joelho de corredores em comparações inter e intragrupos.

RESUMO

OBJECTIVE: This study investigated the effects of star-shape Kinesio taping (KT) compared with both sham KT and minimal intervention (MI) on pain intensity and postural control. DESIGN: Randomized controlled trial. SETTING: Outpatient physical therapy. PARTICIPANTS: A total of 120 people with chronic low back pain (CLBP) aged 18-60 years (N=120). INTERVENTIONS: Star-shape KT, sham KT (no tension), and MI (educational booklet for self-management counseling). MAIN OUTCOME MEASURES: The primary outcome measures were pain intensity and center of pressure (COP) mean sway speed, and disability score (Oswestry Disability Index) was a secondary outcome. The outcomes were obtained immediately after initial KT application, on the seventh day of intervention and at the 1-month follow-up. Linear mixed-model analyses using Bonferroni post hoc analyses were applied to investigate between-group differences. The model included treatment, time, and treatment×time interaction as fixed effects. RESULTS: Pain intensity was significantly lower for the star-shape KT group than for the MI group (mean difference [MD], -1.35; 95% confidence interval [CI], -2.63 to -0.07) immediately after the intervention and on the seventh day of intervention (MD, -1.32; 95% CI, -2.56 to -0.07). No difference in pain intensity between star-shape KT vs sham-KT groups was observed. In addition, no significant between-group differences were observed for the COP mean sway speed and disability score at any of the follow-up times. CONCLUSIONS: Our results showed no meaningful effect of star-shape KT intervention on pain intensity and postural control in people with CLBP compared with MI or sham KT. The observed reduction of 1.3 units between star-shape KT and MI groups was statistically different, but it could not be considered clinically relevant. The results of this trial suggest that benefits from KT are more likely attributable to contextual factors rather than specific taping parameters.
