Abstract
Background: Kinesiotapping (KT) is an elastic tape used for treating sports injuries and other disorders, it was claimed that KT supports injured muscles, joints and relieve pain. Purpose of the study was to investigate the effect of kinesiotaping on electrical activity and peak torque of the dominant quadriceps femoris muscle during concentric and eccentric contraction in healthy subjects. Design: pre test post test control group design. Subjects: two hundred subjects participated in this study. They were divided randomly into two equal groups group A with a mean age of 25.7 ± 2.1 years. They received kinesiotapping on three heads of quadriceps Vastus Medialis, Vastus Lateralis, Rectus Femoris. group B with a mean of 25.9 ± 2.31 years. They received placebo kinesiotapping on quadriceps muscle. Methods: Measuring the electrical activity of the three heads of quadriceps using Electromygraphy, and peak torque of quadriceps using Biodex III isokynetic dynamometer, before tapping, after 10 minutes of tapping, after 24 hours, after 72 hours, and after 5 days (after removal of tape). Results: the VM electrical activity improved in all measurement times, VL improved after 10 min., and rectus femoris increased after 10 min
