Togu Jumper is a both sides utilized balance training device, which consists of an inflated rubber hemisphere attached to a rigid platform. It has been shown to be effective in improving postural control but there are no recommendations for the usage of the sides. Our aim was to examine leg muscle activity and kinematics in response to a single-leg stance on the two sides of the Togu Jumper and the floor. In 14 female subjects, linear acceleration of leg segments, segmental angular sway, and myoelectric activity of 8 leg muscles were recorded in the three stance conditions. Except gluteus medius and gastrocnemius medialis, all muscles were more active when balancing on either Togu Jumper side compared to the floor ( < 0.001), but there was no difference between the two sides in any muscles. Linear acceleration was the greatest in the frontal plane on the flat Togu side in the case of the foot ( < 0.001). Pelvis acceleration was unaffected by the balance conditions. Segmental angular sway was the greatest in the frontal plane, on the bladder side in the foot segment ( < 0.001). No difference was found among the three conditions (all > 0.05) in the case of the shank, thigh, and pelvis. The use of the two Togu Jumper sides produced different balance strategies in the foot segment and induced no difference in equilibrium procedures at the level of the pelvis.
托古跳跃器是一种双侧使用的平衡训练装置，它由一个附着在刚性平台上的充气橡胶半球组成。已证明它在改善姿势控制方面有效，但对于两侧的使用没有相关建议。我们的目的是研究在托古跳跃器两侧和地面上单腿站立时腿部肌肉活动和运动学情况。在14名女性受试者中，记录了三种站立条件下腿部各节段的线性加速度、节段角摆动以及8块腿部肌肉的肌电活动。除了臀中肌和腓肠肌内侧头外，与在地面上相比，在托古跳跃器任何一侧进行平衡时所有肌肉都更活跃（<0.001），但两侧任何肌肉之间均无差异。就足部而言，在平坦的托古侧额平面内线性加速度最大（<0.001）。骨盆加速度不受平衡条件影响。节段角摆动在额平面内最大，在足部节段膀胱侧（<0.001）。在小腿、大腿和骨盆方面，三种条件之间未发现差异（均>0.05）。使用托古跳跃器的两侧在足部节段产生了不同的平衡策略，而在骨盆水平的平衡程序上未引起差异。
