Effect of Rigid Tapping on Chronic Functional Ankle Instability in Basketball Players

Lateral ankle sprains (LASs) are common injuries in sports and physical activities, with up to 40% of individuals experiencing a first-time LAS developing chronic ankle instability (CAI). LASs predominantly affect the anterior talofibular ligament, and residual symptoms can persist in a significant percentage of patients. However, many individuals with ankle sprains do not seek professional treatment, leading to potential underestimation of the injury severity. CAI is characterized by recurrent episodes of ankle giving way, ongoing symptoms, reduced ankle range of motion, diminished self-reported function, and persistent ankle sprains beyond one year. It is attributed to both mechanical and functional instability, with factors such as proprioceptive deficits and mechanical insufficiencies contributing to the condition. Taping, particularly rigid taping, is commonly used by athletes to enhance joint stability and improve dynamic balance and functional performance. Rigid taping limits joint movement, improves joint position, and provides external support without compromising functional performance. Taping is especially prevalent in multidirectional sports like basketball, where ankle sprains are frequent. The use of tapes aims to restrict ankle movement, increase joint stability, and enhance proprioception without hindering athletic performance.
