Ankle sprains are the most common sports-related injuries in the United States, accounting for an estimated 2 million injuries per year.1 This correlates to significant time away from games and practices. A practical method of decreasing the number and severity of these injuries would obviously be of great benefit. For this reason, the concept of prophylactic ankle wrapping was introduced more than 60 years ago.2 The purpose of this article is to review the mechanics of ankle taping and to discuss ankle bracing.

Ankle sprains occur in nearly all types of sporting events. To understand ankle sprains, one must first understand ankle anatomy. The ankle joint (or talar joint) has 3 bones and 3 groups of stabilizing ligaments. The talus articulates in a hinge fashion with both the tibia and the fibula. The distal tibia and fibula are stabilized by the tibiofibular ligaments (anterior and posterior), also known as the syndesmosis.
The thick deltoid ligament supports the medial aspect of the ankle and helps to limit eversion. The medial ankle is inherently more stable than the lateral ankle and is, therefore, the site of fewer injuries. Most ankle sprains are inversion injuries involving either complete or partial tearing of the lateral ligament complex, which is composed of 3 distinct ligaments: the anterior talofibular, the calcaneofibular, and the posterior talofibular. These ligaments are usually injured in a sequential fashion from anterior to posterior, depending on the severity of the inversion.
In contrast to previous beliefs, rapid lateral body movement actually accounts for relatively few inversion sprains. Most ankle sprains occur when landing from a jump, with the foot in an inverted, plantar-flexed position.1,3,4,5 Several studies support the theory that ankle sprains frequently involve disruption in ankle proprioception preventing the ankle from being able to protect itself. Eversion ankle sprains, on the other hand, are usually are not related to inadequate proprioception but are the result of outside forces (eg, contact with another player).
Studies examining the effectiveness of external ankle stabilization have had conflicting results. Some reports show no change in injury rates, most have found at least some decrease in inversion sprains although the mechanism for this protection is still somewhat unclear. It seems logical that external devices should increase the structural stability of the ankle (ie, "stiffen the ankle joint") and make the ankle less susceptible to inversion. Although this is true to some extent, at least one study has shown that regular taping can lose most of its supportive effect after only short periods of exercise.
How, then, do taped ankles or braced ankles decrease the incidence and severity of sprains in taped or braced athletes? The answer most likely lies in a study by Robbins, which found that taped participants had improved proprioception both before and after exercise compared with untaped controls.6 The author theorized that the traction and/or pressure imparted to the skin of the foot and ankle via taping or bracing provided improved sensory input and, thus, improved proprioception, resulting in fewer ankle sprains.
Another study comparing the neuromuscular properties of taped versus untaped ankles introduced a measure known as the proprioceptive amplification ratio (PAR).7 This number incorporates neuromuscular properties such as proprioception and degree of mechanical stress. These results indicated that taping did provide increased ankle protection.
Another common concern often expressed by the public is that prolonged taping or bracing of the ankle results in weak ankles that then become more prone to injury; this would obviously be a strong case against the use of ankle taping or ankle bracing. However, Cordova et al studied the effects of consistent ankle brace use on the peroneus longus muscle, an important stabilizer of the ankle, particularly against inversion, the most common type of ankle injury.8 This study showed that peroneus longus latency to inversion was not changed by the prolonged wearing of an ankle brace.
Several different methods of skin preparation are used in today's athletic training rooms. The most common is to simply clean and dry the lower leg, ankle, and foot. A layer of prewrap (a thin, foamlike material) is applied to the area to be taped. Some athletes prefer to shave the hair from around the area and to have the tape applied directly to the skin. A quick drying adherent is recommended and may be sprayed onto the skin to allow for better tape adhesion. Often, heel and lace pads (foam squares with petroleum jelly or other lubricant) are applied to areas of high friction (ie, the dorsum of the ankle and the distal Achilles tendon) to prevent blisters.
General principles of ankle taping9
Types of tape
Many different types of athletic tape are manufactured. For standard ankle application, the tape of choice is 1.5- or 2-in (3.8- or 5.1-cm) white, porous, athletic tape or nonelastic tape.
Position
The ankle should be in the neutral position (90°). The athlete should be seated comfortably, with the knee at full extension and only the distal half of the lower leg off the table (see Images 1-2).
Preparation
See Skin preparation.
Realizing that some steps are optional, prepare for taping as follows: (1) clean and dry the skin, (2) apply tape adherent, (3) apply heel and lace pads, and (4) apply prewrap from the midfoot to one third of the way up the lower leg.
Procedure
There are several variations on a standard tape application for the ankle. The following is one of the more commonly used techniques taught to undergraduate athletic trainers:
Variations
The standard tape job described has many variations. To discuss them all would go beyond the scope of this article; therefore, only a few of the simpler changes are mentioned.
The concept of ankle bracing evolved from ankle taping. Braces are being used instead of traditional taping by many athletes at all levels of competition. They offer several advantages in that they are self-applied, reusable, and readjustable. In the long run, they are likely more cost-effective than taping.1,9,10,11,12
Braces generally come in 2 types, although small variations exist depending on the manufacturer. The first is nonrigid and resembles a thick canvas or nylon lace-up sock. Some nonrigid braces are also made of neoprene. The nonrigid style imparts some compression to the ankle and may help in injury prophylaxis but provides little medial or lateral stability to the ankle.
The second type of ankle brace is the semirigid. Its construction is similar to the nonrigid but with the added feature of molded plastic struts or air cushions. These are incorporated into the medial and lateral sides of the brace, similar in orientation to the stirrups used in ankle taping. These braces provide more stability and are often are chosen during the rehabilitation and return-to-play phases of ankle injury.
Most nonrigid and semirigid braces also use fabric straps to simulate heel locks. These are usually on the outside of the brace and fastened with Velcro.
Many athletes do not feel as comfortable or as stable wearing braces relative to taping, which can be a disadvantage to treatment. Braces also can become torn or lost and require replacement.
Many studies have been completed comparing taping versus bracing of the ankle to try and determine which is the better method. Prospective studies have met with difficulty in controlling all of the variables associated with ankle injuries (eg, playing surface, shoe wear, individual inherent stability, intensity of competition on both a team and individual level). Most have shown that braces are slightly more effective than taping but that both are better than no support. One interesting study found that simply wearing high-top instead of low-top shoes prevented some ankle injuries and that high tops plus taping had more than 50% fewer injuries than low tops plus taping.
The CAST trial was a randomized controlled trial designed to estimate the clinical effectiveness and cost-effectiveness of 3 methods of ankle support compared with double-layer tubular compression bandage.13 Results of the study showed that the below-knee cast and the Aircast brace offered cost-effective alternatives to tubular bandage for acute severe ankle sprains, with the below-knee cast having the advantage in terms of overall recovery at 3 months. Because no differences in long-term outcome were noted, the investigators suggest that practitioners should consider likely compliance and acceptability to patients when choosing a brace.13
Ankle taping and bracing are fixtures of both athletic training and sports medicine.9,14 Although studies regarding effectiveness and technique are not all in agreement, it seems clear that bracing or taping of the ankle will continue to be a mainstay in the prepractice and precompetition routine.
The sports medicine physician should understand the concepts and techniques of ankle bracing and taping so that advice and guidance can be offered to athletes and athletic training staff. Ankle bracing and taping should not be used in place of aggressive rehabilitation, including strengthening and proprioceptive exercises. Rather, both should be used in conjunction with rehabilitation in terms of injury prevention.
