What is the maximum stretch of kinesiology tape before application?

The correct answer is that kinesiology tape should be stretched to a maximum of 140% of its original length before application. This stretching technique is crucial because it allows the tape to provide optimal support and resistance when applied to the skin. Kinesiology tape is designed to mimic the elasticity of human skin, so properly stretching it helps to ensure that it can effectively facilitate movement while reducing pain and supporting muscle function.

Stretching the tape beyond this recommended limit (for example, to 160% of its original length) could compromise the adhesive properties, leading to premature failure of the tape or discomfort for the patient. Similarly, applying the tape with insufficient stretch (like 100% or even 120%) may not activate the full therapeutic benefits that kinesiology taping is intended to provide, such as enhanced circulation and support. Thus, adhering to the 140% stretch guideline balances effective application and patient comfort, making it the standard practice among practitioners.
