Abstract

Objective: To examine the inter-rater reliability and construct validity of a Movement Quality Score (MQS) within the Standard Physical Therapy Assessment (SPTA) across diagnostic groups.

Design: Cross-sectional study.

Subjects and methods: Eighty-four hospitalized patients undergoing rehabilitation for neurological, musculoskeletal, or internal medical conditions were included. Inter-rater reliability was assessed in 68 participants independently evaluated by 2 physiotherapists. The MQS was scored using the SPTA component. Inter-rater reliability of the summed score was analysed using the intraclass correlation coefficient (ICC [2,1]). Construct validity was examined using Spearman's rank correlations between the MQS and the Functional Independence Measure (FIM) motor total score and its subdomains (self-care, sphincter control, transfers, and locomotion), as well as other SPTA components.

Results: The MQS demonstrated excellent inter-rater reliability (ICC [2,1] = 0.93). It showed a very strong correlation with the FIM motor total score (ρ = 0.91, p < 0.001), with strong associations for transfers and locomotion (ρ = 0.92) and self-care (ρ = 0.86). The correlation with sphincter control was lower (ρ = 0.68).

Conclusion: The MQS demonstrates excellent reliability and strong construct validity, supporting its use as a movement-focused complement to activities of daily living-based assessments in heterogeneous rehabilitation populations.

一种用于康复评估的跨诊断运动质量评分的信度和结构效度。

目的：探讨标准物理治疗评估（SPTA）中运动质量评分（MQS）在不同诊断组间的信度和结构效度。设计：横断面研究。对象和方法：84例因神经、肌肉骨骼或内科疾病接受康复治疗的住院患者被纳入研究。由2名物理治疗师独立评估68名参与者的评分者间信度。使用SPTA组件对MQS进行评分。采用类内相关系数（ICC[2,1]）分析总得分的等级间信度。结构效度采用Spearman等级相关性来检验MQS与功能独立测量（FIM）运动总分及其子域（自我护理、括约肌控制、转移和运动）以及其他SPTA组件之间的关系。结果：MQS具有良好的量表间信度（ICC[2,1] = 0.93）。结论：MQS具有良好的信度和较强的构效度，支持其作为异质性康复人群日常生活活动评估的补充。
