摘要

Objective: The purpose of this investigation was to examine the effects of therapeutic taping (no tape, placebo, Kinesiotape, Leukotape) on lower extremity electromyographic (EMG) activity during three functional tasks (sit to stand, squat, vertical jump). Design: One group, repeated measures design. Subjects: Ten normal and healthy university students (4 females, 6 males; mean age 24 years ± 7.1; height 170 cm ± 10.8; and body mass 69 kg ± 14.4). Methods: Subjects completed four testing sessions with different tape (no tape, placebo, a mechanical correction type of technique with Kinesiotape and Leukotape). Three trials of a sit to stand, squat, and vertical jumping task were completed. Four Delsys dipole EMG instruments with two input channels each were used to measure mean surface EMG activity for the erectorspinae, gluteus medius, vastus lateralis, vastus medialis obliques, semitendinosus, lateral gastrocnemius, tibialis anterior, and peroneus longus muscles. The data were analysed using descriptive statistics and repeated measures ANOVAs. The rejection criteria were set at an alpha level p < .05. Results: Subjects' EMG muscle activity demonstrated a significant interaction effect between the type of tape and muscle type (F(21, 2848)=2.728, p=.0005, η~(2)=.02) with significant differences in muscle type EMG activity for placebo and Leukotape. A statistically significant interaction effect was also evident between the functional task and muscle type (F(14, 2856)=2.956, p=.0005, η~(2)=.014). The highest activation levels were evident for the vastus medialis obliques and tibialis anterior muscles for all functional tasks. A statistically significant interaction effect was also found between the type of tape and functional task (F(6,2868)=2.108, p=.049, η~(2) =.004) with a higher effect on muscle type EMG activity levels when using placebo tape during the vertical jumping task. Conclusions: Different patellar taping techniques do not produce consistent clinical effects via an alteration in muscle EMG activity. Placebo taping had the greatest effect on EMG activity for most muscles; the vastus medialis obliques and tibialis anterior had the greatest increase in EMG activity with the application of all types of tape. Other taping techniques have been described to inhibit or facilitate lower quadrant muscle activity and, as a result, future research in a symptomatic population comparing facilitatory to inhibitory taping techniques may produce further information on the exact clinical effects on EMG activity as compared to a mechanical correction technique.
