目的：本研究目的為利用25度拉筋台面產生的拉筋刺激，造成人體站姿平衡的維持與型態的不穩定，加以探討視覺介入對三維站姿區段關節晃動的影響。方法：受試者以銘傳大學健康男大學生10名（年齡：23.5 ± 0.5歲，身高：167.1 ± 4.8公分，體重：58.5±4.8公斤，BMI：20.9 ± 2.6 kg/m^2），自願為研究對象。所有受試者雙腳赤足、雙手抱胸，前後站姿於斜台面拉筋板上，接受一分鐘睜眼與閉眼等兩種不同情境之站姿，及接受各五次的量測。斜台面拉筋板為自行設計，台面傾斜最大角度設定為25度。並使用無線動作擷取系統（PhaseSpace® system），擷取踝關節部、膝關節部、髖關節部、肩關節部與頭頂部等晃動軌跡，加以分析人體前後站姿動作型態變化與探討平衡的控制機制。資料取樣頻率為480 Hz，取樣時間為60秒。所有統計檢定，以成對樣本t檢定，進行睜眼與閉眼條件差異的考驗。考驗水準設定為α=.05。結果：在閉眼條件下膝關節部、髖關節部、肩關節部、及頭頂部區段之擺幅三維體積，都較大於睜眼情境，且達顯著水準。結論：本研究利用25度拉筋台面刺激，有效造成人體站姿型態的差異與瞭解視覺介入對三維站姿平衡的特性。未來研究方向，應加以分析專項運動選手與健康平衡適能的量測，以提供作為後續站姿平衡研究基礎的參考。

Purpose: The purpose of this study was to identify the effect of the visual intervention (eyes open or closed) on three-dimensional (3D) segment-joint sways in standing. These effects were determined using a stretch board, which was inclined to 25° to induce postural instability in participants' standing and balance maintenance. Methods: The participants were ten healthy male students from Ming Chuan University (age: 23.5 ± 0.5 years, height: 167.1 ± 4.8 cm, body weight: 58.5 ± 4.8 kg, and body mass index: 20.9 ± 2.6 kg/m^2) who volunteered to participate in this study. All participants were required to stand on the inclined stretch board with bare feet, hands crossed over chest, and one foot forward. Their standing postures were measured when their eyes were open and when their eyes were closed for 1 min each; five measurements were recorded for each scenario. The stretch board was designed by the researchers, and the maximum inclination angle was 25°. A wireless motion-capture system (PhaseSpace® system) was used to capture motion trajectories of the ankle, knee, hip, shoulder, and head top. The captured data were analyzed to determine participants' postural changes when they stood with a foot forward and to explore the mechanism of balance control. The data were sampled at 480 Hz for 60 s. Paired samples t tests were conducted to analyze the difference between eyes-open and -closed scenarios. The test level was set to α = .05. Results: The sway amplitudes of the knee, hip, shoulder, and the head top in the eyes-closed scenario were significantly greater than those in the eyes-open scenario. Conclusion: The stimulus of the stretch board inclined at 25° caused differences between participants' standing postures in eyes-open and -closed scenarios and enabled identification of the effect of the visual intervention on 3D postural balance in standing. Future studies should analyze the measurement of balance fitness for athletes in different sports and for other healthy people to provide a reference for subsequent research regarding standing-posture balance.
