- Existing ankle prophylactics are reported to restrict other joint motions (plantar- and dorsi-flexion), while limiting the ankle inversion that leads to joint injury (McCaw and Cerullo, 1999). Consequently, existing ankle prophylactic devices may impair the functional capacity of the joint, leading to increased re-injury and chronic instability.
- Ankle prophylactic products are purported to produce a significant decrease in whole-body functional performance, including: impaired balance (Bennell and Goldie, 1994), reduced maximum vertical jump height (Metcalfe et al., 1997; Paris, 1992) and increased time to perform an agility test (Metcalfe et al., 1997; Rosenbaum et al., 2005).
- Wearing an ankle prophylactic that restricts other ankle motions, subsequently changes the activation of the underlying muscles potentially limiting the joint (Barlow et al., 2015). This limitation may subsequently prevent the restoration of proprioceptive, neuromuscular, and sensorimotor capabilities necessary for healthy joint function with the use of existing prophylactic products on an injured ankle. Therefore, existing prophylactic device designs may contribute to a high rate of re-injury and lead to the development of chronic ankle instability in users as time passes.
- The ideal ankle prophylactic product would not restrict the typical anatomical joint motions, but rather only prevent excessive joint motion at the anatomical limit - positions where ligament damage, and subsequent injury begins (Garrick and Requa, 1973). This design would: (a) prevent excessive ankle inversion that leads to initial and re-injury of the joint, while (b) not impairing joint and whole-body functional performance, potentially leading to a reducing the development of chronic ankle instability. With that in mind, an innovative prophylactic product – Ankle Roll Guard – was recently patented...This novel design results in a device that allows the user to maintain normal ankle motion (i.e., typical anatomical joint motions) and functional capacity of the joint. Yet, still adds the mechanical stability necessary to prevent injury of the ankle.
- All prophylactic devices (ARG, Brace and Tape) prevented the excessive ankle inversion that is thought to lead to injury. But only the ARG appears to allow the user normal ankle motion (i.e., typical anatomical joint motions), while preventing excessive ankle inversion.
- the ARG does not prevent “other” typical ankle motions during the sudden inversion event. Ankle braces that impair these ankle motions may increase the chances of mechanical and functional instabilities at the joint (Gutierrez et al., 2009). As such, the ARG may have an advantage for the user and reduce the likelihood they develop either mechanical or functional instability at the joint when worn.
- Taking longer to reach the peak inversion angle may be indicative of greater mechanical restriction provided by an ankle prophylactic and potentially results in a decreased risk of suffering an ankle injury when wearing that particular device. But, it also may represent a reduction of the user’s natural joint motion. This restriction may lead to mechanical and functional instabilities of the joint and reduce whole-body performance for the user.
- The current outcomes suggest an ankle prophylactic device can have a significant effect on the wearer’s physical performance. This significant reduction in vertical jump performance may be attributed to two things: (1) a decrease in the plantarflexion (i.e., natural) motion at the ankle; and (2) the subsequent reduction in positive work performed by the ankle that results when wearing a restrictive ankle prophylactic device, such as the Brace or Tape, during the vertical jump. Specifically, participants exhibited greater range of ankle plantarflexion with the ARG (39.5°) and Control (37.5°) compared to both the Brace (34.0°) and Tape (33.8°) conditions.
- "...participants performed significantly greater positive work at the ankle, and exhibited higher vertical jumps, with both the ARG and Control compared to the Brace and Tape conditions. Thus, it appears that the ARG and Control conditions, because they afford for greater range of ankle plantarflexion during the vertical jump than the Brace or Tape, allows the wearer to produce more muscular effort at the ankle and subsequently better vertical jump performance.
- Conclusion: The ARG may provide similar prevention of excessive inversion as either the Brace or Tape, but without the mechanical restriction of the joint that reportedly limits physical performance when wearing ankle prophylactic devices. With the ARG, participants exhibited more natural ankle motions (i.e., plantarflexion) during both the sudden inversion event and vertical jump. This motion allowed the participants to perform better during the vertical jump with the ARG as compared to the more restrictive braces (i.e., Brace and Tape).

I bought this for my mom who has had a couple of strokes & her ankle rolls. I’m amazed how this keeps her ankle from rolling & how stable her foot is. Highly recommend.
