Differences and Changes in Lower Limb Muscle Activation and Ankle Stability in Different Blackboard Configurations

"Participants will perform three attempts of 20 seconds of single-leg stance on the floor and on the 7 selected configurations of the BB. The order of measurement will be randomized. The description of the chosen configurations can be found in the Detailed Description section. In all cases, the participant's objective is to ensure that the edges of the BB are not in contact with the floor.~The position of the participant on the BB will be a single-leg stance on the randomly chosen foot, with the contralateral knee slightly flexed and hands placed on the hips. Participants will look at a fixed point placed 3 meters in front of them.~A rest period of 30 seconds will be allowed between trials. The physiotherapist responsible for supervising the measurements will be the one to adjust the BB configurations when needed."
