Elastic therapeutic tape, also called kinesiology tape or kinesiology therapeutic tape, Kinesio tape, k-tape, or KT [1] is an elastic cotton strip with an acrylic adhesive that is purported to ease pain and disability from athletic injuries and a variety of other physical disorders. [2] [3] [4] In individuals with chronic musculoskeletal pain, research suggests that elastic taping may help relieve pain, but not more than other treatment approaches, and no evidence indicates that it can reduce disability in chronic pain cases. [5]
No convincing scientific evidence indicates that such products provide any demonstrable benefit in excess of a placebo, with some declaring it a pseudoscientific treatment. [6] [7]
Kenzo Kase, a Japanese-American chiropractor, developed the product in the 1970s. The company he founded markets variants under the brand name "Kinesio" and takes legal action to prevent the word being used as a genericised trademark. [2]
A surge in popularity resulted after the product was donated to Olympic athletes in the 2008 Beijing Summer Olympics and 2012 London Summer Olympics. [8] [9] The tapes' prominence and mass introduction to the general public have been attributed to Kerri Walsh who wore the tape on her shoulder, and who along with Misty May-Treanor dominated the 2008 beach volleyball event. [10] In 2012, science journalist Brian Dunning speculated on why he had not seen "a single athlete, pro beach volleyball players included, wear Kinesio Tape outside of the Olympics". He believes that "sponsorship dollars may be entirely responsible for the popularity of Kinesio Tape during televised events." [11]
The product is a type of thin, elastic cotton tape that can stretch up to 140% of its original length. [12] As a result, if the tape is applied stretched greater than its normal length, it will "recoil" after being applied and therefore create a pulling force on the skin. This elastic property allows much greater range of motion compared to traditional white athletic tape and can also be left on for long periods before reapplication. [13]
Designed to mimic human skin, with roughly the same thickness and elastic properties, the tape can be stretched 30–40% longitudinally. [12] It is a latex-free material with acrylic adhesive, which is heat activated. The cotton fibers allow for evaporation and quicker drying leading to longer wear time, up to 4 days. [14] How the tape is claimed to affect the body is dependent on the location and how it is applied; the stretch direction, the shape, and the location all supposedly play a role in the tape's hypothetical function. [14]
Manufacturers have made a wide variety of claims, including that it provides physical support for muscles, tendons, ligaments, and joints. [15] KT Health's web site at one point claimed the tape "lifts the skin, decompressing the layers of fascia, allowing for greater movement of lymphatic fluid which transports white blood cells throughout the body and removes waste products, cellular debris, and bacteria". [16] This increase in the interstitial space purportedly reduces pressure on the body's nociceptors, which detect pain, and stimulates mechanoreceptors, to improve overall joint proprioception. [17] Critics say these claims are not supported by evidence. [7]
In the 2012 article "Scientists sceptical as athletes get all taped up", Reuters reported that "In a review of all the scientific research so far, published in the Sports Medicine journal in February, researchers found 'little quality evidence to support the use of Kinesio tape over other types of elastic taping in the management or prevention of sports injuries". [8] Some researchers claim that what athletes are experiencing is just a placebo effect. [18]
In July 2012, Steven Novella writing in Science-Based Medicine in the article "Olympic Pseudoscience'", examined the use of KT in the larger context of "sports-related pseudoscience". Novella says "The world of sports competition is rife with pseudoscience, false claims, dubious products, superstitions, and magical charms." Novella concluded that "Consumers should be very skeptical of claims made for products marketed as athletic performance enhancing." [6]
In August 2012, science journalist Brian Dunning reports in "Kinesio Tape: The Evidence" that positive studies of the tape are the result of people being deceived by a "stage magician's trick" – which he describes in detail – that is used to fool subjects into thinking strength or flexibility is being affected, when they are not. He reports that kinesio tape is claimed to be good for a plethora of issues including "pain management, injury treatment, injury prevention, enhanced performance, increased range of motion, and just about anything else an athlete might want." He concludes: "It sounds like a miracle — one simple product that does everything you can imagine. In short, a textbook snake oil product." [11]
A 2012 meta analysis found that the efficacy of elastic therapeutic tape in pain relief was trivial, because no reviewed study found clinically important results. The tape "may have a small beneficial role in improving strength, range of motion in certain injured cohorts, and force sense error compared with other elastic tapes, but further studies are needed to confirm these findings". [17] [ unreliable medical source? ] The same article concluded: "KT had some substantial effects on muscle activity, but it was unclear whether these changes were beneficial or harmful. In conclusion, there was little quality evidence to support the use of KT over other types of elastic taping in the management or prevention of sports injuries" [17] [ unreliable medical source? ]
A 2014 meta analysis looked at methodological quality of studies, along with overall population effect, and suggested that studies of lower methodological quality are more likely to report beneficial effects of elastic therapeutic taping, thus indicating the perceived effect of using kinesio taping is not real. It also suggested that applying elastic therapeutic tape, "to facilitate muscular contraction has no, or only negligible, effects on muscle strength". [19]
A 2015 meta analysis found that the taping provided more pain relief than no treatment at all, but was not better than other treatment approaches in patients with chronic musculoskeletal pain. [5] The same meta analysis did not find any significant changes in disability as a result of taping. [5]
In March 2018, Science-Based Medicine again examined KT in response to its public use at the 2018 Winter Olympics in the article A Miscellany of Medical Malarkey Episode 3: The Revengening. The article reports that:
The claims made by manufacturers and promoters of the tape are highly implausible, particularly those involving increased muscle strength, improved blood flow to an injured areas, and better lymphatic drainage to reduce swelling. No evidence supports these claims. Pain reduction and injury prevention are also frequently-cited benefits that similarly lack evidence, at least none showing an effect specific to kinesio tape... There is no evidence of a specific benefit related to kinesio tape itself, or to any kind of expert application of it. [7]
In November 2018, Science-Based Medicine describes a new study published the same month in the online journal BMC Sports Science, Medicine and Rehabilitation which examines the effectiveness of different colors of kinesiology tape, as well as reexamining general effectiveness of kinesiology tape against a placebo. Describing the conclusions of the study, they write:
Nothing mattered. Tape color didn't matter. Color preference didn't matter. "Proper" placement of KT with tension didn't matter. No effect on performance, strength, or function was found in any experimental round compared to the control round for any of the subjects. [20]
In 2017, KT Health settled a class action lawsuit in Massachusetts, resolving claims of unjust enrichment and untrue and misleading marketing. It agreed to pay $1.75 million to refund half the purchase price of the tape, representing the premium paid above traditional athletic tape. [16] The brand also agreed to drop claims that the tape "will keep you pain-free", "prevents injury", or provides "24-hour pain relief", and add the disclaimer "not clinicially proven for all injuries". [16]
Massage is the rubbing or kneading of the body's soft tissues. Massage techniques are commonly applied with hands, fingers, elbows, knees, forearms, feet, or a device. The purpose of massage is generally for the treatment of body stress or pain. In European countries, a person professionally trained to give massages is traditionally known as a masseur (male) or masseuse (female). In the United States, these individuals are often referred to as "massage therapists". In some provinces of Canada, they are called "registered massage therapists."
Osteopathy, unlike osteopathic medicine, which is a branch of the medical profession in the United States, is a pseudoscientific system of alternative medicine that emphasizes physical manipulation of the body's muscle tissue and bones. In most countries, practitioners of osteopathy are not medically trained and are referred to as osteopaths.
Rolfing is a form of alternative medicine originally developed by Ida Rolf (1896–1979) as Structural Integration. Rolfing is marketed with unproven claims of various health benefits, is recognized as pseudoscience and has been characterized as quackery. It is based on Rolf's ideas about how the human body's "energy field" can benefit when aligned with the Earth's gravitational field.
Achilles tendinitis, also known as Achilles tendinopathy, is soreness of the Achilles tendon. It is accompanied by alterations in the tendon's structure and mechanical properties. The most common symptoms are pain and swelling around the back of the ankle. The pain is typically worse at the start of exercise and decreases thereafter. Stiffness of the ankle may also be present. Onset is generally gradual.
Cupping therapy is a form of pseudoscience in which a local suction is created on the skin with the application of heated cups. As alternative medicine it is practiced primarily in Asia but also in Eastern Europe, the Middle East, and Latin America. The practice of cupping has been characterized as quackery.
Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy. Cryotherapy can be used in many ways, including whole body exposure for therapeutic health benefits or may be used locally to treat a variety of tissue lesions.
Manual therapy, or manipulative therapy, is a part of Physiotherapy, it is a physical treatment primarily used by physical therapists, occupational therapists to treat musculoskeletal pain and disability; it mostly includes kneading and manipulation of muscles, joint mobilization and joint manipulation. It is also used by Rolfers, massage therapists, athletic trainers, osteopaths, and physicians.
Athletic training is an allied health care profession recognized by the American Medical Association (AMA) that "encompasses the prevention, examination, diagnosis, treatment, and rehabilitation of emergent, acute, or chronic injuries and medical conditions." There are five areas of athletic training listed in the seventh edition (2015) of the Athletic Training Practice Analysis: injury and illness prevention and wellness promotion; examination, assessment, diagnosis; immediate and emergency care; therapeutic intervention; and healthcare administration and professional responsibility.
Applied kinesiology (AK) is a pseudoscience-based technique in alternative medicine claimed to be able to diagnose illness or choose treatment by testing muscles for strength and weakness.
Heat therapy, also called thermotherapy, is the use of heat in therapy, such as for pain relief and health. It can take the form of a hot cloth, hot water bottle, ultrasound, heating pad, hydrocollator packs, whirlpool baths, cordless FIR heat therapy wraps, and others. It can be beneficial to those with arthritis and stiff muscles and injuries to the deep tissue of the skin. Heat may be an effective self-care treatment for conditions like rheumatoid arthritis.
A sprained ankle is an injury where sprain occurs on one or more ligaments of the ankle. It is the most commonly occurring injury in sports, mainly in ball sports such as basketball, volleyball, football, pickleball, and tennis.
An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. The most common injury is a complete tear. Symptoms include pain, an audible cracking sound during injury, instability of the knee, and joint swelling. Swelling generally appears within a couple of hours. In approximately 50% of cases, other structures of the knee such as surrounding ligaments, cartilage, or meniscus are damaged.
Therapeutic ultrasound refers generally to any type of ultrasonic procedure that uses ultrasound for therapeutic benefit. Physiotherapeutic ultrasound was introduced into clinical practice in the 1950s, with lithotripsy introduced in the 1980s. Others are at various stages in transitioning from research to clinical use: HIFU, targeted ultrasound drug delivery, trans-dermal ultrasound drug delivery, ultrasound hemostasis, cancer therapy, and ultrasound assisted thrombolysis It may use focused ultrasound or unfocused ultrasound.
Patellofemoral pain syndrome is knee pain as a result of problems between the kneecap and the femur. The pain is generally in the front of the knee and comes on gradually. Pain may worsen with sitting down with a bent knee for long periods of time, excessive use, or climbing and descending stairs.
Aquatic therapy refers to treatments and exercises performed in water for relaxation, fitness, physical rehabilitation, and other therapeutic benefit. Typically a qualified aquatic therapist gives constant attendance to a person receiving treatment in a heated therapy pool. Aquatic therapy techniques include Ai Chi, Aqua Running, Bad Ragaz Ring Method, Burdenko Method, Halliwick, Watsu, and other aquatic bodywork forms. Therapeutic applications include neurological disorders, spine pain, musculoskeletal pain, postoperative orthopedic rehabilitation, pediatric disabilities, pressure ulcers, and disease conditions, such as osteoporosis.
Straining of the hamstring, also known as a pulled hamstring, is defined as an excessive stretch or tear of muscle fibers and related tissues. Hamstring injuries are common in athletes participating in many sports. Track and field athletes are particularly at risk, as hamstring injuries have been estimated to make up 29% of all injuries in sprinters. Hamstring injuries can also come with a hip injury from sprinting. Symptoms for a hip injury are pain, aching and discomfort while running or any physical exercise.
Platelet-rich plasma (PRP), also known as autologous conditioned plasma, is a concentrate of plasma protein derived from whole blood, centrifuged to remove red blood cells but retaining platelets. Though promoted for treating various medical conditions, evidence of its benefits was mixed as of 2020, showing effectiveness in certain conditions and ineffectiveness in others.
Growth hormones in sports refers to the use of growth hormones for athletic enhancement, as opposed to growth hormone treatment for medical therapy. Human Growth Hormone is a prescription medication in the US, meaning that its distribution and use without a prescription is illegal. There is limited evidence that GH doping improves athletic performance, although the perception that it does is common in the sporting community. Potential side effects of long term GH doping could mirror the symptoms found in sufferers of acromegaly, a disease in which the anterior pituitary gland produces excess growth hormone. These symptoms include swelling of the hands and feet, joint pain, fluid retention, and excessive sweating.
Athletic taping is the process of applying tape directly to the skin or over pre-wrap in order to maintain a stable position of bones and muscles during athletic activity. It is a procedure that uses athletic tape, attached to the skin, to physically hold muscles or bones at a certain position. This reduces pain and aids recovery. Taping is usually used to help recover from overuse and other injuries.
Flywheel training is a type of strength training where the resistance required for muscle activation is generated by the inertia of a flywheel instead of gravity from weights as in traditional weight training.
