下肢骨骼手術者肌力復原影響因素之探討

Factors Affecting Muscle Strength Recovery After Lower Limb Operation

本研究目的在了解某醫學中心下肢骨骼手術者肌力復原之影響因素，以徒手肌力測試法重複測量200位下肢骨骼手術患者，術後第一至第七天的股四頭肌肌力值。研究資料使用SPSS 11.5和SAS軟體執行樣本屬性之描述性分析及影響術後肌力好壞因素之廣義估計式（GEE）統計分析。結果發現影響術後肌力復原好壞之因素有疼痛分數、下床活動時間及不同手術別，其中大腿骨骼復位者較膝關節置換者肌力復原好；術後疼痛分數愈低，術後肌力復原愈好；下床活動時間30-60分鐘者，較少於30分鐘者及超過60分鐘者肌力復原好。

Factors Affecting Muscle Strength Recovery after Lower Limb Operation The purpose of this study was to examine factors associated with recovery of muscle strength after lower limb surgery at one medical center. Two hundred subjects who underwent lower limb surgery were studied. The muscle strength of the quadriceps femoralis muscle was measured with repeat manual muscle testing from postoperative days 1 to 7. All data was analyzed for descriptive and GEE statistical analysis using SPSS 11.5 computer programs and the Statistical Analysis System (SAS). The results showed a significant relationship between muscle strength and both total knee replacement (TKR) and femoral reduction. The patient's muscle strength during time out of bed was measured from 30 to 60 minutes, was better than less 30 minutes and exceed 60 minutes. TKR was less than the femoral reduction.
