During physical activity, the integrity of a joint and its associated structures can be compromised, especially during high-risk activities that may introduce injurious mechanisms. Sports medicine clinicians can supplement mechanical support to a joint through a variety of taping techniques using elastic and nonelastic materials. Guidelines have been established that define taping procedures as standard interventions for domains such as “prevention” and “immediate care.”
Taping techniques are utilized extensively by athletic trainers and other sports medicine professionals to prevent excessive joint movements, especially in sports known to have a high risk for particular injuries. For example, an individual is at an increased risk for a lateral ankle sprain during participation in the sport of basketball, compared with the sport of baseball. Therefore providing additional support to the ankle complex of a basketball player in order to restrict motions outside the anatomical limits is a common preventative measure performed to reduce the risk of an injury to the joint structures. A variety of taping techniques designed for prevention exist that are designed to limit unwanted joint motion or provide biomechanical support to a joint to alleviate discomfort during movement. In addition, a clinician, after evaluating the structures that may have suffered an injurious mechanism during participation in an activity, may determine that the individual can return back to participation with immediate care of supplementing joint stability with a taping technique.
Taping interventions may be employed with either elastic or nonelastic tape using several techniques. Taping materials are available from multiple manufacturers and come in a range of widths and lengths. Elastic tape, which is typically made in widths between 1 and 4 inches (2.5 to 10.2 cm), is used to provide some additional stability while still allowing a large freedom of movement, to secure pads or other protective implements to a body part, or to provide compression. Nonelastic tape can provide more joint support than elastic tape using applications intended to restrict excessive movements, and comes in typical widths between 1 and 2 inches (2.5 to 5.1 cm). Tape may be applied directly to skin that has been shaved or devoid of hair (i.e., sole of the foot), or if the patient does not wish to shave the area that will be taped, a thin layer of foam, called prewrap, may be wrapped around and over the skin surface to be taped.
A newer material used frequently in clinical practice is self-adherent tape and prewrap. This material will adhere to itself, but does not stick to the skin. In addition, it is a very pliable material, with high tensile properties, meaning it can be molded very easily to a body part and still provide a level of mechanical stiffness. The theoretical advantage is that it can provide less skin irritation compared to traditional nonelastic and elastic adhesive tape materials. In addition, the self-adherent prewrap is believed to contribute to the mechanical strength of the taping technique, while regular prewrap does not.
Prophylactic taping techniques can be applied to any part of the body, and there are many variations on the techniques used to apply the nonelastic and elastic materials. Because lower extremity injuries are more prevalent in sports, and these injuries are more likely to be preventable through taping techniques than upper extremity injuries, this overview will focus on some common techniques and associated outcomes related to foot, ankle, and knee taping. It should also be noted that any taping technique may, and often is, modified by a clinician to meet the preventative and treatment needs and comfort of the patient. Therefore the following descriptions are suggested guidelines for some of the more common taping techniques used in sports medicine settings.
Plantar fasciitis or fasciosis is estimated to affect more than 10% of the general population. The most common causes of this pathology relate to a high body mass index, and increased pronation of the midfoot with subsequent flattening of the medial longitudinal arch. Pain persisting along the midfoot extending to the insertion of the plantar fascia at the calcaneus, especially with the first few steps after a period of non-weight-bearing, may benefit from added support to the midfoot. Low-dye and other forms of arch support taping techniques are intended to supplement the structural support of the medial longitudinal arch and the plantar fascia that creates a windlass mechanism needed for normal ambulation.
These taping techniques involve strips of tape that initiate over the insertion of the plantar fascia at the calcaneus or encircle the heel and then extend to the base of each metatarsal head. Elastic or nonelastic tape can be used, with inch widths typically employed. The strips will slightly overlap each other, with a strip that secures the tape under the metatarsal heads. Versions of low-dye taping typically involve continuing a strip of tape under the medial longitudinal arch, and pulling up toward the lateral surface of the shank, effectively pulling the foot out of a pronated position ( Fig. 33.1 ). Additional strips of elastic tape may be wrapped around the midfoot to support the fan shaped collection of strips supporting the arch of the foot.
In a systematic review, van de Water and Speksnijder examined the short-term effects of taping techniques on treating pain and disability associated with plantar fasciosis. The limited evidence reviewed showed a positive short-term effect (<1 week) on pain reduction with taping techniques compared with control conditions and other interventions, but the evidence was inconclusive on the impact on patient disability. Similar positive short-term effects of taping on stiffness were observed by in combination with iontophoresis, with continued benefits observed after 4 weeks of continued treatment. Relief of pain and symptoms through external support of the foot beyond a week may require additional interventions, such as orthotics, which is discussed later in this chapter.
Sprains to the first metatarsophalangeal (MTP) joint are common in field sports and can be quite debilitating. “Turf toe,” as it is commonly called, can result from a hyperextension or hyperflexion mechanism to the great toe (first MTP joint), which limits dorsiflexion of the great toe and restricts the ability of the patient to push off during ambulation. A taping technique may be employed to resist the painful motion of the MTP joint by looping inch strips of tape to pull the toe into flexion or extension. Additional strips are wrapped around the midfoot to anchor the strips and complete the technique.
The most common anatomical injury among the physically active is to the ankle. Subsequently, taping of the ankle for preventive and immediate treatment purposes is the most common technique used in clinical practice. Due to anatomical and biomechanical principles, the lateral ligaments are the most commonly affected structures of the ankle complex. The purpose of a typical ankle taping technique is to limit plantar flexion and inversion of the ankle complex, which are injurious movements associated with a lateral ankle sprain.
The most common technique for providing support to the lateral ankle complex is called the “closed basket weave.” Typically performed with 1.5 inch nonelastic tape, the strips of tape are applied as “anchors,” “stirrups,” and “heel-locks,” which will cover the ankle complex from the midshank distally to the tarsals ( Fig. 33.2 ). The combination of strips will position the ankle complex into a dorsiflexed and slightly inverted position. The strips of nonelastic tape may be applied either to skin that has been shaved or over a layer prewrap. In addition, thin square foam pads with petroleum jelly may be placed over the insertion of the Achilles tendon on the calcaneus and over the talus, to reduce friction over these skin areas that may suffer irritation from the crossing of the applied strips of tape.
To provide mild stability and compression to an acutely injured ankle, a clinician may utilize an “open basket weave” taping technique. The sequence of application of the anchor and stirrup strips of nonelastic tape is similar to the closed basket weave technique, but the crisscrossing heel locks are not applied with nonelastic tape, leaving the dorsum of the foot exposed ( Fig. 33.3 ). The heel locks are applied with elastic tape under small amounts of tension, or with an elastic bandage. This technique allows some support to ankle complex with the primary purpose to provide comfortable compression to help minimize the early stages of the inflammatory process.
There are many forms of external prophylactic support for the knee, with rigid braces being the choice most clinicians use for long-term wear and prevention. However, there are taping techniques that can be applied to provide stability to the knee joint during physical activity. Most available knee braces are designed to supplement the cruciate and/or collateral ligaments of the knee. Taping techniques can be applied to mimic or supplement the limitations to knee movement these rigid braces are intended to create.
Protection against excessive valgus or varus forces that may threaten the medial and lateral collateral ligaments can be achieved by crisscrossing strips of tape over the medial or lateral surfaces of the knee joint and securing them proximally and distally to the thigh and shank ( Fig. 33.4 ). Additional support can be provided to the cruciate ligaments with this technique by wrapping these crisscrossed strips around the anterior and posterior aspects of the thigh and shank ( Fig. 33.5 ). The angle of each strip is varied in order to comprehensively support the knee joint complex.
Patellofemoral pain syndrome (PFPS) is a classification of pathology that presents with anterior knee pain or retropatellar pain. The etiology of PFPS has multiple origins, with many attributed to malalignment and poor tracking of the patella in relation to the femoral groove, resulting in pain. One of the many treatments proposed to alleviate the symptoms of PFPS are taping techniques to reposition the patella statically and dynamically. A systematic review by Aminaka and Gribble concluded that patellar corrective taping techniques have positive outcomes for alleviating pain and improving function, but the explanatory mechanisms are not well established by the existing literature. This is likely a result of the complexity and variability of the pathology, which also helps explain why there are so many variations on patellar taping techniques.
A basic tenet of patellar taping techniques is to determine what form of malalignment and maltracking the patient is suffering from (i.e., patella alta, medial rotation, etc.), and then attempt to pull and reposition the patella, using specialized tape, into the opposite direction or combination of directions. The specialized tape is then used to maintain the corrected position, in order to alleviate excessive pressures between the posterior surface of the patella and the trochlear groove of the femur. One popular collection of these techniques was developed by McConnell, but many variations on these techniques exist and may be successful for individual patient needs. In general, these applications are intended to be worn for longer periods of time (days or weeks; see the section below), as the symptoms may persist beyond physical activity into activities of daily living. Subsequently, specialized, and often more expensive, taping materials are utilized. A common technique is to draw the patella medially, using the tape to hold the position statically, and encourage a new movement pattern during dynamic positioning that prevents lateral patellar displacement during a strong contraction of the quadriceps muscle group ( Fig. 33.6 ). Additional adjustments in the tilt, rotation, and vertical placement of the patella can be made with the taping technique.
The materials used for most athletic taping techniques are not designed for long-term wear. These materials provide a significant amount of stability and movement limitation immediately after application, with most of the published evidence focused on ankle taping techniques. However, because they are cloth-based products, exposure to moisture, heat, and tension will quickly reduce the biomechanical stiffness properties of the materials, in as little as 10 minutes after application. One study suggests that while both elastic and nonelastic cloth-based tapes will lose tensile strength after 30 minutes of exercise, elastic tape may not lose as much tension as nonelastic tape, and may be more comfortable. Limited investigation on the amount of joint restriction after application and participation in exercise on the newer category of self-adherent tape materials suggests these newer materials may provide more sustainable stability to the ankle, specifically in restricting inversion movement, compared with nonelastic cloth tape. More research is needed to determine how to improve the restrictive properties of taping materials to maximize their effectiveness.
Evidence on the optimal time period of lasting strength of taping materials used in treating foot and knee conditions discussed in this chapter is quite limited. One can only project that the properties of taping materials that have been studied related to ankle taping would apply to the materials if they are used on other joints of the lower extremity and are subjected to similar demands of physical activity. In most cases, taping techniques are designed for short-term wear (a few hours) before being removed. While a taping technique may be applied every day for many weeks or months (i.e., the length of a sport competition season), some techniques, like the Low-Dye and arch support techniques for plantar fasciitis, are typically applied as an intermediary until a more permanent orthotic can be obtained for the patient.
The exception to this are the materials used for patellofemoral corrective taping. These are applied with the intent of the patient wearing the material on the skin potentially for several days in order to receive a benefit of the repositioned patella during all forms of physical and daily living activities. These materials are constructed of more robust material that resists moisture and maintains its mechanical stiffness. The cost of these materials, such as Leukotape (Beiersdorf, Inc., Wilton, CT), is much higher per roll than cloth-based elastic and nonelastic tapes, and would severely limit joint movement, which explains why clinicians may choose not to use these materials in the daily application of most of the taping techniques that have been described in this chapter.
There is an ongoing debate in the literature and in clinical practice as to what is the most effective and cost-efficient prophylactic support for reducing injury in the lower extremity. Typically the comparisons are between taping and bracing of the joints of the lower extremity. While taping is a staple among sports medicine clinicians, there is a relatively limited amount of investigation into the efficacy of taping techniques for the prevention of injury, with the majority of this literature focused on ankle injuries.
In general, ankle taping has been shown in clinical studies to reduce the rate of ankle sprain. In an early study, Garrick and Requa reported that taping produced a twofold decrease in ankle sprains in intramural basketball players with a history of an ankle sprain, and a threefold decrease in players who had no history of ankle sprains. The literature continues to suggest that this intervention is effective at reducing ankle injury rates during physical activity and sport participation compared with not wearing a prophylactic support. Similarly, a large amount of research supports the use of prophylactic ankle braces for the reduction of ankle sprain incidence. However, the existing evidence does not seem to support a difference in the effectiveness of ankle taping versus ankle bracing, meaning both forms of prevention are useful in reducing ankle sprain incidence. Short- and long-term cost of materials may be an important deciding factor, which will be discussed later in the chapter.
While low-dye and other taping techniques are used successfully in clinical practice to alleviate excessive pronation and plantar fasciitis and fasciosis symptoms, the published evidence is quite limited. Typically this treatment is used initially to alleviate symptoms, but long-term use commonly is avoided in favor of other forms of mechanical correction and support to the foot through orthotics and other forms of tissue treatment to reduce inflammation and irritation. Supporting the clinical use of this technique, a systematic review concluded that taping techniques are a short-term effective treatment for pain associated with plantar fasciitis/fasciosis, but the evidence is inconclusive for supporting these techniques to improve disability. Similarly, a more recent investigation stated that low-dye taping was able to decrease patient-reported pain during walking and jogging immediately after application, but long-term effects were not assessed. Therefore it appears that these taping techniques can provide an immediate and short-term resolution of pain in patients with plantar fasciitis.
