比較間歇加壓循環機不同充氣模式之下肢壓力變化：以假肢模型為例
Comparison of the Effects of Different Inflation Pressures of Intermittent Pneumatic Compression in Lower Limbs Using a Lower Limb Mannequin
摘要
近幾年間歇加壓循環機（intermittent pneumatic compression, IPC）已經被視為一種運動後的恢復工具。過去研究中僅針對IPC介入後效果進行分析。目的：使用IPC進行不同充氣模式下踝、小腿、膝、大腿之氣壓壓力及充氣時間差異比較。方法：本研究利用下肢假肢模型及IPC三種不同氣壓充氣模式（A模式：同肢段充氣後放氣、B模式：同肢段充氣後保持氣壓後放氣、C模式：所有肢段同時充氣後放氣）進行檢測，加壓強度則是利用壓力感測器及自製程式測量，壓力感測器置於腿部袖套內（踝、小腿、膝、大腿處），以袖套拉鍊橫向距離10公分為基準，測試IPC在不同充氣模式之下肢壓力值及充氣時間之差異，資料處理以單因子變異數進行分析。結果：結果顯示在B模式下，充氣時間在踝（74.12s）顯著大於大腿（25.91s，p＜.05），A模式及C模式則無顯著差異。在同一模式下，氣壓壓力均無顯著差異。結論：本研究了解IPC充氣模式之充氣壓力及充氣時間，以作為未來運用在選手運動後恢復之用。

Purpose: In recent years, intermittent pneumatic compression (IPC) has attracted attention as a potential recovery tool for athletes. Previous studies have focused only on the post intervention effects of IPC. Therefore, this study aimed to understand and compare the magnitude of pressure and inflation time of IPC applied on a lower limb mannequin in different inflation modes. Methods: An artificial lower limb mannequin and an IPC device were used for experiments in three different inflation modes (Mode A: inflation followed by deflation in the same segment; Mode B: air pressure inflation hold followed by and then deflation in the same segment; and Mode C: inflation followed by deflation in all segments). A pressure sensor was placed inside the garment (10 cm transversely away from the zipper) to measure the pneumatic pressure in each segment (ankle, calf, knee, and thigh) and detect changes in pressure. One-way analysis of variance was used to analyze the limb pressure and inflation time in the three different inflation modes. Results: The results of this study indicated that the inflation time in the ankle (74.12 s) was significantly more than that in the thigh (25.91 s) in Mode B (p ＜ .05). No significant differences among the inflation times and limb pressures in the different modes. Conclusion: The inflation mode, inflation time, and limb pressure of IPC are suitable for recovery in sportspersons. However, because the experiments in this study were performed on a lower limb mannequin, in vivo trials should be conducted in future studies.
