Kinesiotaping Techniques to Alter Static Load in Patients With Foot Pronation

Objective: This study aimed to assess the effect of kinesio tape (KT) application on foot pronation using the laser postural alignment system. Methods: Twenty participants (10 females and 10 males, mean age 19.7 +/- 1.2 years) with foot pronation were included in the study. The laser line projected on the participant by the laser postural alignment system showed the joint load carrying line. The location of the joint load carrying line was assessed during barefoot static standing with one foot on the force plate before KT application, immediately after application, then 24 and 48 hours later. Displacement of the load-carrying line was measured using a ruler placed tangentially to the patella and ankle joint at the level of the joint line. Weight bearing on the barefoot was assessed before KT application, immediately after, then 24 and 48 hours later. Results: Weight bearing was not significantly changed after KT application. The load-carrying line measured using KT did not notably move with KT versus without KT in the ankle joint. Immediately after KT application, significant lateral knee joint movement was measured, but this change was not importantly 24 and 48 hours later. Conclusion: KT was not altered in changing weight bearing or moving the lower extremity load-carrying line in people with foot pronation. KT of the foot can amplify sensory input and improve perceived comfort; therefore, it can be used with an orthotic insole in footwear.
