目的：建立護理之家院民下肢被動關節活動度與姿勢評估量表之施測者內信度。方法：共收集10位平均年齡為71.3歲，年齡範圍在58～79歲之間之8位男性和2位女性志願者（l位為無任何病史的老人，另9位為神經系統方面疾病的患者）參與本研究。由同一位施測者用萬用量角器(goniometer)測量其下肢被動關節活動度（包括髖屈曲與伸直、膝屈曲與伸直、踝關節背曲與蹠屈），並用「中風病人姿勢評估量表」(Postural Assessment Scale for Stroke Patients)評估其姿勢，兩次施測間相隔一週。結果：護理之家院民下肢被動關節活動度之施測者內信度之組內相關係數(ICC)以膝屈曲的0.965為最高，踝蹠屈的0.561為最低，中風病人姿勢評估量表之總分之級內相關係數為0.989。下肢被動關節活動度與姿勢評估量表在兩次測量平均值之間皆無差異(p>0.05)。結論：護理之家院民之下肢被動關節活動度測量之施測者內信度達中等至高的信度，而姿勢評估量表則可獲得極佳之施測者內信度。

Purposes: The purpose of this study was to establish intrarater reliabilities of goniometric measurements of the lower extremity passive range of motion and the 'Postural Assessment Scale for Stroke Patients' (PASS) for posture in nursing home residents. Methods: Ten nursing home residents with or without neurological diseases (mean age=71.3 years; 8 males, 2 females) participated in this study. An experienced physical therapist assessed the lower extremity range of motion, including hip flexion and extension, knee flexion and extension, and ankle dorsi-flexion and plantar-flexion, with goniometer and posture with PASS. One week later, the subjects were assessed again by the same physical therapist. Results: Intrarater reliabilities of the goniometric measurement of passive lower extremity range of motion ranged from 0.561 (ankle plantar-flexion) to 0.965 (knee flexion). Intrarater reliabilities of PASS was excellent for postural assessment (ICC=0.989). Conclusions: Moderate to high intrarater reliabilities for goniometry measurement of lower extremity passive range of motion and excellent intrarater reliabilities were found for postural assessment with PASS in nursing home residents.
