Effects of Kinesio tape on pain, muscle strength and functional performance: a systematic review of Japanese language literature.

Background: The current English language research evidence does not support the clinical use of Kinesio tape (KT). Objectives: This systematic review aimed to collect and synthesise unexplored Japanese language primary studies investigating effects of KT on pain, muscle strength and functional performance. Methods: Nine databases were systematically searched from inception to 8 February 2017. Methodological quality was assessed using the McMaster Critical Review Quantitative Form. Data were synthesised descriptively. Results: Six studies with moderate to high risk of bias were included. There was limited evidence for positive effects of KT on isokinetic knee extension and flexion strength, which was in line with the current English language literature. There was also limited evidence to support the use of KT to prevent the compromise of agility performance after exhaustive exercises. Conclusions: This systematic review of Japanese language primary studies found limited, inconclusive evidence about the effectiveness of KT on muscle strength and functional performance. Further studies with better methodological rigour are required in Japanese, and in English, to improve the strength of the current evidence base. [ABSTRACT FROM AUTHOR]
