To cross-culturally adapt and psychometrically analyse the Italian version of the Trunk Impairment Scale on acute (cohort 1) and chronic stroke patients (cohort 2).
The Trunk Impairment Scale was culturally adapted in accordance with international standards. The psychometric testing included: internal consistency (Cronbach's alpha), inter- and intra-rater reliability (intraclass correlation coefficient; standard error of measurement and minimal detectable change), construct validity by comparing Trunk Impairment Scale score with Barthel Index, motor subscale of Functional Independence Measure, and Trunk Control Test (Pearson's correlation), and responsiveness (Effect Size, Effect Size with Guyatt approach, standardized response mean, and Receiver Operating Characteristics curves).
The Trunk Impairment Scale was administered to 125 and 116 acute and chronic stroke patients, respectively. Internal consistency was acceptable (α > 0.7), inter- and intra-rater reliability (ICC > 0.9, Minimal Detectable Change for total score < 1.6 in cohort 1 and < 1.1 in cohort 2) were excellent. The construct validity showed acceptable correlations (r > 0.4) with all scales but the motor Functional Independence Measure in cohort 2. Distribution-based methods showed large effects in cohort 1 and moderate to large effects in cohort 2. The Minimal Important Difference was 3.5 both from patient's and therapist's perspective in cohort 1 and 2.5 and 1.5 from patient's and therapist's perspective, respectively, in cohort 2.
The Trunk Impairment Scale was successfully translated into Italian and proved to be reliable, valid, and responsive. Its use is recommended for clinical and research purposes. Implications for Rehabilitation Trunk control is an essential part of balance and postural control, constituting an important prerequisite for daily activities and function. The TIS administered in subjects with subacute and chronic stroke was reliable, valid and responsive. The TIS is expected to help clinicians and researchers by identifying key functional processes related to disability in people with subacute and chronic stroke.
对急性卒中患者（队列1）和慢性卒中患者（队列2）进行《躯干功能障碍量表》意大利语版本的跨文化调适及心理测量学分析。
按照国际标准对《躯干功能障碍量表》进行文化调适。心理测量测试包括：内部一致性（克朗巴哈系数）、评分者间信度和评分者内信度（组内相关系数；测量标准误和最小可检测变化）、通过比较《躯干功能障碍量表》得分与巴氏指数、功能独立性测量运动子量表以及躯干控制测试（皮尔逊相关）进行结构效度分析，以及反应度分析（效应量、采用盖亚特方法的效应量、标准化反应均值和受试者工作特征曲线）。
分别对125例急性卒中和116例慢性卒中患者施测《躯干功能障碍量表》。内部一致性可接受（α＞0.7），评分者间信度和评分者内信度均极佳（组内相关系数＞0.9，队列1总分的最小可检测变化＜1.6，队列2＜1.1）。结构效度显示，除队列2的运动功能独立性测量外，与所有量表的相关性均可接受（r＞0.4）。基于分布的方法在队列1中显示出较大效应，在队列2中显示出中度至较大效应。队列1中，从患者和治疗师角度来看，最小重要差异均为3.5；队列2中，从患者和治疗师角度来看，最小重要差异分别为2.5和1.5。
《躯干功能障碍量表》已成功翻译成意大利语，并被证明具有可靠性、有效性和反应度。建议将其用于临床和研究目的。康复意义躯干控制是平衡和姿势控制的重要组成部分，是日常活动和功能的重要前提条件。对亚急性和慢性卒中患者施测的《躯干功能障碍量表》具有可靠性、有效性和反应度。预计《躯干功能障碍量表》将有助于临床医生和研究人员识别与亚急性和慢性卒中患者残疾相关的关键功能过程。
