To investigate the validity and reliability of the Turkish version of the Ottawa Sitting Scale (OSS-T) in patients with acute stroke.
The Berg Balance Scale (BBS) and Trunk Impairment Scale (TIS) were used to determine the validity of the OSS-T. The OSS-T was re-applied by the same rater after an interval of 7 days to determine the reliability. To test inter-rater reliability, the evaluation was repeated by a second rater 1 day after the first evaluation. Reliability was quantified using intraclass correlation coefficients (ICC), and validity was assessed by correlating the OSS-T scores with the results of the other measures.
The ICC of the total OSS-T score for inter-rater reliability was 0.996 and for intra-rater reliability, it was 0.951. The Cronbach's coefficient used to determine internal consistency was 0.980, which indicates excellent reliability. A strong positive correlation was found between OSS-T and TIS (rho = 0.861, < 0.001), and between OSS-T and BBS (rho = 0.875, < 0.001). An evident 2-factor structure was shown by the results of the factor analysis.
The results of this study indicated that the OSS-T has strong measurement properties, making it a valid and reliable tool for research and clinical practice in patients with acute stroke.IMPLICATIONS FOR REHABILITATIONIndependent sitting function is an important indicator of functional recovery and discharge from hospital.Unlike other sitting balance tools, the Ottawa Sitting Scale can even categorize patients with low balance reserve by applying all the items with and without foot support.The Turkish version of the Ottawa Sitting Scale is a valid and reliable tool to evaluate sitting balance in patients with acute stroke.
调查急性脑卒中患者使用土耳其版渥太华坐立量表（OSS-T）的有效性和可靠性。
使用 Berg 平衡量表（BBS）和躯干损伤量表（TIS）来确定 OSS-T 的有效性。由同一位评估者在 7 天后间隔重新应用 OSS-T 以确定可靠性。为了测试组内可靠性，由第二位评估者在第一次评估后 1 天重复评估。使用组内相关系数（ICC）来量化可靠性，通过将 OSS-T 评分与其他测量结果相关联来评估有效性。
OSS-T 总分的组间可靠性 ICC 为 0.996，组内可靠性 ICC 为 0.951。用于确定内部一致性的 Cronbach's 系数为 0.980，表明具有极好的可靠性。OSS-T 与 TIS 之间存在很强的正相关（rho = 0.861， < 0.001），OSS-T 与 BBS 之间也存在很强的正相关（rho = 0.875， < 0.001）。因子分析的结果显示了明显的 2 因素结构。
本研究结果表明，OSS-T 具有很强的测量特性，使其成为急性脑卒中患者研究和临床实践中有效的可靠工具。
独立坐立功能是功能恢复和出院的重要指标。与其他坐立平衡工具不同，渥太华坐立量表甚至可以通过应用有和没有足部支撑的所有项目来对低平衡储备的患者进行分类。土耳其版渥太华坐立量表是评估急性脑卒中患者坐立平衡的有效且可靠的工具。
