目的:一、驗證因職災而導致上肢受傷的勞工個案，醫療穩定後參加工作強化訓練前 後之上肢失能、疼痛酸麻程度與生活品質之相關性。二、探討年齡、介入時數、工作強化 訓練前後上肢失能、疼痛酸麻症狀等變項對於工作強化訓練前後之生理及心理生活品質的 影響。方法:取自台灣南部某工作強化中心 2010 年 10 月至 2013 年 4 月之病例，採病 例回溯的方式。收案條件:1. 診斷為上肢功能受損之職災個案;2. 醫療狀況穩定並完成 4周以上工作強化訓練。共得病例 32 份。收集個案在工作強化訓練前後之上肢失能程度(上 肢失能問卷 Disabilities of the arm, shoulder and hand questionnaire)、疼痛與酸麻程度 (視覺類比量表 Visual Analogue Scale)、生活品質生理範疇及心理範疇(台灣簡明版 世界衛生組織生活品質問卷 WHO Quality of Life-BREF)。統計分析包含描述性統計、Pearson 相關係數與逐步回歸。結果:有 26 位男性與 6 位女性，平均年齡 43.8 歲。工作 強化介入時間平均約為 60 小時。以訓練前(後)生活品質生理範疇與心理範疇為依變項， 年齡、介入時數、訓練前(後)之上肢失能程度、疼痛程度、酸麻程度為自變項。結果指 出:在工作強化訓練前，生活品質生理範疇的顯著影響變項為上肢失能程度與酸麻程度; 生活品質心理範疇的顯著影響變項則為酸麻程度。經工作強化訓練後，生活品質生理範疇 的顯著影響變項為上肢失能程度與年齡;生活品質心理範疇的顯著影響變項則為上肢失能 程度。結論:此結果提醒職能治療人員在介入上肢功能損傷職災勞工時，致力減輕疼痛與 酸麻程度並減少上肢失能，可以有效提高個案之生活品質。

Objective: First, it is to examine the correlations between upper extremity disability, the degree of pain and numbness and quality of life in workers with occupational injury in upperextremity. Second, it is to investigate the in uence of the age, hours of work-hardening, upperextremity dysfunction, pain and numbness to physical and psychological domains of quality of life before and after work-hardening training. Methods: The retrospective study reviewed the work-hardening records from 32 subjects in a Taiwan work-hardening center during 2010 to 2013. All of the subjects were workers occupational injury in upper extremity injury and completed work-hardening training. The data of disabilities of the arm, shoulder and hand (DASH) questionnaire, the degree of pain and numbness and the physical and psychological domains of the World Health Organization Quality of Life (WHOQOL) questionnaire before and after work hardening were collected. Statistical analysis included descriptive statistics,Pearson correlation coef cient and stepwise regression. Results: There were 26 males and 6 females, and average age was 43.8 years old. Average intervention hour was about 60hours. The ndings indicated that before work hardening the numbness and DASH were the signi cant variables for the physical domain in WHOQOL; the numbness was the signi cantvariable for the psychological domain in WHOQOL. After work hardening, both the age andDASH were the signi cant variables for the physical domain in WHOQOL, and the DASH wasthe significant variable for the psychological domain in WHOQOL. Conclusion: In order toimprove the quality of life for the workers with upper extremity injury, the ndings suggestedthat occupational therapists could make effort to reduce the degree of upper extremity disability and alleviate their pain and numbness.
