目的:探討產後女性的軀幹傾斜角度與步態、平衡能力和足底壓力。方法:本 研究隨機招募了 20 名產後女性和 20 名健康未懷孕女性為對照組，使用 Zebris 足底壓力板收取受試者的步態、平衡和足底壓力參數，實驗中同時配戴 Balance Gear 平衡評測感測器評收取受試者的軀幹傾斜角度，實驗流程包括開/閉眼靜態 站立和步態測試，最後將所有數據匯入電腦進行統計分析。結果:產後女性僅 在步速顯著低於未懷孕女性 (p < .05)，步長、步幅、步寬等步態參數未達顯著差 異。產後女性開眼 COP 顯著小於未懷孕女性，閉眼 COP 兩組則無達顯著差 異，而產後開/閉眼 COP 位移速度皆顯著小於未懷孕女性。產後女性的足底壓 力有異常分佈，產後中足壓力顯著大於未懷孕女性、前足壓力顯著較小，後足 兩組則無差異，最後在軀幹傾斜角度產後顯著大於未懷孕組。結論:本篇研究 實證產後女性在部分參數與健康未懷孕女性顯著不同，產後步速慢、有較大的中足 足底壓力和較小前足足底壓力和軀幹前傾現象，此現象可能代表存在相對肌肉骨骼 問題，因此產後八週後到六個月內女性有恢復訓練重要性。

Objective: To explore trunk inclination angles, gait, balance abilities, and plantar pressure in postpartum women. Methods: This study randomly recruited 20 postpartum women and 20 healthy non-pregnant women as the control group. The Zebris plantar pressure plate was used to collect gait, balance, and plantar pressure parameters, while the Balance Gear balance assessment sensor measured trunk inclination angles. The experimental procedure included static standing tests with eyes open and closed, as well as gait tests. All data were subsequently imported into a computer for statistical analysis. Results: Postpartum women demonstrated significantly lower gait speed compared to non-pregnant women, with no significant differences observed in other gait parameters such as step length, stride length, and step width. Postpartum women also had significantly smaller COP (Center of Pressure) areas with eyes open compared to non- pregnant women, while no significant differences were noted between the two groups with eyes closed. The COP velocity was significantly lower in postpartum women under both eyes-open and eyes-closed conditions. Additionally, postpartum women exhibited an abnormal distribution of plantar pressure, characterized by significantly higher midfoot pressure and significantly lower forefoot pressure compared to non-pregnant women, while rearfoot pressure did not differ between the two groups. Lastly, trunk inclination angles were significantly greater in postpartum women than in the non-pregnant group. Conclusion: This study demonstrates that postpartum women differ significantly from healthy non-pregnant women in specific parameters , which may indicate underlying musculoskeletal issues. Therefore, appropriate rehabilitation training is recommended for postpartum women between eight weeks and six months postpartum.
