KT Tape May Not Be All That Helpful for Joint, Muscle Pain

Kinesio taping — also known as KT tape — may dampen joint and muscle pain in the short term, but the evidence is highly uncertain, an overview of systematic reviews showed.

KT tape may reduce pain intensity in the immediate and short term (Hedges’ g −0.69 and −0.57, respectively) and also improve function and disability right away (Hedges’ g −0.54), but the evidence wasn’t definitive, reported Xiaoyan Zheng, PhD, of Southern Medical University in Guangzhou, China, and colleagues.

And inconclusive evidence showed the treatment had only trivial effects on pain intensity in the medium term, on function and disability in the short and medium term, and on muscle strength and range of motion, they noted in BMJ.

“Kinesio taping is widely used in clinical practice, yet the evidence base has remained conflicting,” Zheng told MedPage Today in an email.

Zheng said previous systematic reviews focused only on statistical significance without asking whether the effects were actually meaningful to patients. Those reviews also weren’t optimal for considering the quality of the evidence or the potential for overlapping and low-quality studies, she noted.

The current research “addresses these gaps by providing a comprehensive overview of both published and unpublished systematic reviews, assessing methodological quality, and evaluating clinical relevance across different follow-up periods,” Zheng said.

“This is particularly important now because clinicians and patients need clear, trustworthy guidance on whether KT offers real benefits beyond a placebo or short-term relief,” she added.

Russell Camhi, DO, a primary care sports medicine physician with Northwell Orthopedics in New York, who was not involved in the study, told MedPage Today in an email that the findings are “in alignment” with expectations.

KT tape “can occasionally be effective in helping alleviate pain,” Camhi said, but it’s “not surprising that the results were variable and overall showed that KT does not significantly reduce pain.”

KT taping was initially invented in the 1970s. The idea is that applying it to the skin with enough tension may lift the skin, stimulate sensory receptors, promote proprioception, and enhance local blood circulation.

Camhi explained that a clinician or physical therapist “places the dysfunctional body part in its proper alignment and then applies the tape.” Then, “[i]f and when the body part moves out of its correct alignment, the tape comes under tension, providing the patient sensory feedback which allows them to then correct their posture.”

Camhi believes the systematic review explores the secondary effects of KT, rather than its “primary role” of providing “proprioceptive feedback.”

Zheng and colleagues’ review showed the most common adverse events related to KT tape were skin irritation (40%) and pruritus (30%), with a number needed to harm (NNH) of 173 for skin irritation and 356 for pruritus, the researchers reported.

Overall, they included 128 systematic reviews (73 published and 55 registered, yet unpublished) involving 15,812 participants from 310 randomized clinical trials in their research.

Many reviews focused on lower extremity conditions (45%) and reported pain intensity (89%). Most were evaluated as critically low (78%) in methodological quality and low (58%) in risk of bias. Median total compliance rate was 75.6% in reporting quality.

The study was limited in that it only considered reviews of trials published in English, limiting its generalizability, the researchers said.

Nonetheless, they concluded that their findings suggest KT tape “may provide benefits in the immediate term,” as its likely these come from the “mechanical support to the subcutaneous space” which is “likely to disappear once the tape is removed, making the effects difficult to maintain in the short or medium term.”

Ultimately, “clinicians should be aware that the evidence for KT is very uncertain overall, and most benefits, where they exist, appear to be limited to short-term outcomes,” Zheng said. Additionally, “KT should not be seen as a substitute for active interventions like exercise, which generally have stronger evidence.”

Also, clinicians “should discuss realistic expectations with patients, including the possibility of only short-term relief and the potential for adverse events such as skin irritation or itching,” Zheng added.

Furthermore, “shared decision-making is important — patients’ preferences and values should be considered alongside the limitations of the current evidence,” Zheng said. “Given the low methodological quality of most existing reviews, clinicians should also interpret published systematic reviews on this topic with caution.”
