This project investigated the effects of Kinesio® Tape on pain, kinesiophobia, and proprioception in participants with patellar tendonitis. Thirty participants with patellar tendonitis were divided into three groups, the first received a supportive Kinesio® Tape application at the knee, the second received a facilitative application at the hip, and the third received both. A Visual Analog Score, Tampa Scale for Kinesiophobia score, and a proprioceptive score quantified through the Biodex Balance System were obtained both immediately after application, and 24 to 36 hours following. Statistically significant improvement in VAS scores and in proprioceptive ability with eyes closed 24 to 36 hours following Kinesio® Tape application was observed under all interventions. Kinesio® Tape application for pain, cause of pain and proprioception may assist patients with patellar tendonitis.
