背景與目的：功能性伸取是重要的日常生活動作，也是臨床上評估平衡能力的依據之一，但有關中風後病患功能性伸取能力之研究卻十分有限。本研究之目的在探究中風患者與健康成年人於改良式功能性伸手取物測試時之表現差異。方法：共有31位健康成年人受試者及31位中風患者參與本研究，於坐姿下進行四種方向（肩關節先曲屈90°，再依水平內收45°、外展角度0°、45°及90°，依序定義為：對側、前側、同側及側邊）之伸取動作，每種方向進行三次測試，並使用電子位移計及類比－數位訊號轉換器記錄每次測試的值。統計分析以獨立t測試及單因子變異數分析檢定組間及組內各方向之差異。結果：中風患者在坐姿下，健側手功能性伸取測試之反應時間、動作速度及伸取之距離皆較健康成年人為差。而各組之各方向間的差異，在伸取距離的表現上，往側邊方向的位移在兩組都是呈現最短，且皆有統計上的差異（P＜0.001與其他方向相比）。結論：中風患者在坐姿下以健側手動作時，其表現還是與健康成年人有所差異，所以臨床治療上或是照顧患者時，除著重患側邊的治療訓練外，也應同時注意健側邊執行動作時的安全性。

Background and Purpose: Functional reach, a useful clinical evaluation tool for balance ability, is one of the major daily activities. In the literature, there are only a few objective and quantitative data regarding this ability for individuals with hemiplegia. The purpose of this study was to investigate the functional reach ability of non-affected side in the individuals with hemiplegia. Methods: Thirty-one subjects with hemiplegia and 31 age-matched healthy adults meeting our selection criteria participated in this study. The four directions of functional reach were defined as follows: shoulder flexion 90° with shoulder horizontal adduction 45° was defined as across reach, horizontal abduction 0° as anterior reach, horizontal abduction 45° as ipsilateral reach and horizontal abduction 90° as lateral reach. Each subject performed three trials in each direction. The reaction time, reaching speed, and reaching distance were recorded and for comparison. Student t-test was used for the between group comparison and one-way ANOVA was used for within group comprising above mentioned measures. Results: Subjects with hemiplegia had longer reaction time, slower movement speed, and shorter reaching distance than healthy subjects. However, the distance for lateral reach was the shortest in the four directions in both groups (p<0.001 versus other positions). Conclusions: The functional reach abilities of non-affected side in individuals with hemiplegia were different from those of healthy subjects. Therapists should be aw are of the deficits even in the non-affected side when treating patients with hemiplegia.
