The effect of kinesio tape application on hamstring and gastrocnemius muscles in healthy young adults

摘要

Background: Scarce evidence exists about effectiveness and mechanisms of action of Kinesio tape (KT) application. Objectives: To evaluate the effect of KT application over the gastrocnemius or hamstring on range of motion and peak force. Methods: Thirty-six physical therapy students participated (18 per group). KT was applied with 30% tension for 48 h to: Group 1 - the gastrocnemius; Group 2 - the hamstrings. The straight leg raise (SLR), knee extension angle (KEA), weight bearing ankle dorsiflexion, gastrocnemius, quadriceps and hamstrings peak forces were evaluated prior to application, 15 min and 48 h after. Results and conclusions: A significant increase of peak force in the gastrocnemius group appeared immediately and two days later; no immediate change of peak force in the hamstrings group, however, two days later, peak force significantly increased. SLR and ankle dorsiflexion increased immediately in the gastrocnemius group; KEA improved significantly only after two days. It is possible that certain muscles react differently when KT is applied, and the effect may be subsequently detected.
