Inclusion criteria

Inclusion criteria: The inclusion criteria required participants were age ranged from 15 to 25 years old and they had all experienced at least 4 years of professional ISS regular exercises, to have a history of at least one inversion ankle sprain that necessitated protected weight bearing, immobilization, and restricted activity for a minimum of 24 hours[25]. The initial sprain must have taken place more than one year before the participant enrolled in the study[26]. Achieving a Cumberland Ankle Instability Tool (CAIT) score of 25 or lower on the affected side[27].

Exclusion criteria

Exclusion criteria: Participants were excluded: The recurrence of ankle sprain injury during the study period, if they had a history of participants were excluded if they had a history of lower extremity injuries that restricted movement [28, 29], any noticeable musculoskeletal deformities in the lower extremities or upper body while in a normal standing posture [30, 31], or if they missed more than three sessions or two consecutive sessions of the intervention program
