The effect of kinesiology tape on respiratory function in adults: A systematic review and meta-analysis

Background: Kinesiology taping may enhance respiratory function in various adult populations; however, current evidence remains limited. This systematic review aimed to review the existing literature on the effects of kinesiology tape on respiratory function in two adult cohorts. Methods: Studies involving adults (≥18 years), including healthy individuals and those with respiratory conditions, were considered. A comprehensive search was conducted using Cochrane methodology across eight electronic databases, a search engine, grey literature sources, and reference lists, guided by PICOS-based keywords. The Cochrane Risk of Bias tool, ROBINS-I, and Grades of Recommendation Assessment, Development, and Evaluation (GRADE) criteria were used to assess the risk of bias and evidence certainty. Results: Eighteen studies were included: eight involving healthy adults and athletes, and 10 focusing on adults with respiratory conditions. A total of 684 participants were enrolled in these studies, comprising 316 healthy individuals and 368 adults with respiratory conditions. Discussion: Respiratory function, cough efficacy, and muscle strength improved mainly in healthy adults, with clinical benefits noted in those with respiratory conditions. The meta-analysis showed no significant effect of kinesiology tape on respiratory function in either healthy adults or those with respiratory conditions. Most of the included studies presented a high risk of bias, and the certainty of evidence was very low. Conclusion: Evidence supporting the use of kinesiology taping to enhance respiratory function in healthy adults and individuals with respiratory conditions remains limited. Further well-designed, condition-specific clinical trials are needed before routine inclusion in respiratory care can be recommended.
