The Effects Of Ankle Braces On Lower Extremity Electromyography And Performance During Vertical Jumping: A Pilot Study, Zachariah J. Henderson Mr., Paolo Sanzo, Carlos Zerpa, Derek Kivi
International Journal of Exercise Science
International Journal of Exercise Science 12(1): 15-23, 2019. Ankle braces have been hypothesized to prevent ankle injuries by restricting range of motion (ROM) and improving proprioception at the ankle. As such, ankle braces are commonly worn by physically active individuals to prevent ankle injuries. Despite their widespread use, the effects that ankle braces have on athletic performance measures, such as vertical jumping, remains unclear. Furthermore, although ankle braces are known to restrict normal ROM at the ankle, little is known about the effects that ankle braces have on the lower extremity proximal to the ankle, specifically muscular activation. Therefore, the …
