Chronic ankle instability was determined by the Identification of Functional Ankle Instability Questionnaire , and participants were randomly assigned to a resistance-band-protocol group ( n = @ -LSB- @ % -RSB- age = @ @ years , height = @ @ cm , weight = @ @ kg ) , a proprioceptive neuromuscular facilitation strength-protocol group ( n = @ -LSB- @ % -RSB- , age = @ @ years , height = @ @ cm , weight = @ @ kg ) , or a control group ( n = @ -LSB- @ % -RSB- , age = @ @ years , height = @ @ cm , weight = @ @ kg ) .
