About this study
Official title: The Impact Of Ankle Brace Use Utilization Versus Functional Taping On Adolescent Athletes With Chronic Ankle Instability
The aim of this study was to compare the effects of an ankle brace, functional taping, and no prophylactic method on maximum inversion angle, inversion velocity, peroneus longus reaction time, and subjective perception of instability during a simulated inversion task in adolescent basketball players with chronic ankle instability. It is hypothesised that the use of these prophylactic methods will result in better outcomes across the analysed variables, potentially contributing to a reduced risk of inversion sprains.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ankle BraceDevice
The ankle brace model used in this study was the STRONG 500 ankle brace (TARMAK, Tourcoing, France). The ankle brace was applied in accordance with the manufacturer's guidelines.
Functional TapingDevice
Functional taping was performed using pre-tape and tape (3.8 cm x 10 cm) from the WolfCare brand (Caxias, Portugal).

|---|---|---|
| Ankle Brace | Experimental | The ankle brace model used in this study was the STRONG 500 ankle brace (TARMAK, Tourcoing, France). The ankle brace was applied in accordance with the manufacturer's guidelines. Receives: Device: Ankle Brace |
| Functional taping | Experimental | Functional taping was performed using pre-tape and tape (3.8 cm x 10 cm) from the WolfCare brand (Caxias, Portugal). Receives: Device: Functional Taping |
| No Prophylactic Method | No intervention | The absence of a prophylactic method refers to data collection from participants who did not have any material applied to the ankle. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum inversion
Highest point of inversion reached after the onset of the inversion. Calculated by determining the absolute difference between the amplitude at the onset of inversion and the point at which the foot reached its maximum inversion (in degrees)
Measured: From the onset of inversion to the point of maximum inversion.
Inversion Velocity
Was calculated from the moment the inversion began until the point at which the mechanical response for eversion started (in degree per second)
Measured: During the inversion-to-eversion movement.
Reaction Time of the Peroneus Longus
Refers to the duration it took for the muscle to initiate contraction following the onset of inversion (in milliseconds)
Measured: From the onset of inversion to the initiation of muscle contraction.
Subjective Perception of Instability
Refers to the sensation that the ankle feels unstable or at risk of giving way during physical activities
Measured: Immediately after the inversion test.
