論新型蹲式馬桶地板結構效能驗證之研究

現今公共場所使用蹲式馬桶時，久蹲易造成下肢痠麻與不易起身等問題，對於年長者與行動不便者易導致使用上的不便。因此本研究運用肌電訊號來探討蹲在不同傾斜角度對大腿與小腿肌肉施力的影響，由實驗數據發現大腿在角度7與17度有顯著性；特別是50歲以上中老年者大腿在角度7度是有顯著性差異。本研究還發現受測者施力點都放在大腿上，而小腿在各種傾斜角度的地板上，施力都比平面來的小，所以推論人在蹲姿時，施力重心都放在小腿上，而傾斜地板有助於大腿與小腿肌肉施力的減少，因此在使用蹲式馬桶上會更符合人因的設計、適用性與便利性。

Nowadays, when using squat toilet of public places, long-squatting easily lead to extremity tingling, get up with difficulty and other issues. So for older people with mobility problems are easy to cause inconvenience to use. Therefore, this study uses EMG to investigate the effects of different tilt angles squatted on the thigh and calf muscle force. The experimental data found that there is a significant difference in the thigh with a 17- degree angle 7. Especially there is a significant difference in the angle 7 those aged over 50 years. Furthermore, we also found that subjects who force points are placed on the thigh, and calf on various tilt angles floor, a small force than planes, so the reasoning at the time of squatting, the focus is on the leg force on the floor and lean thigh and calf muscles help to reduce the force. Therefore, would be more in line with human factors design, applicability and convenience when using squat toilets.
