A valid and reliable assessment tool to describe the quality of the movement pattern of reaching can provide valuable insights into motor performance deficits in persons with MS (pwMS). The Reaching Performance Scale, developed for stroke, is a promising scale to assess movement patterns in pwMS. However, psychometric properties of the scale are lacking in pwMS.
Firstly, to investigate the content validity of the modified Reaching Performance Scale for application in patients with MS (mRPS). Secondly, to investigate the psychometric properties (within- and between-session reliability and concurrent validity) of the mRPS for pwMS.
Forty-five pwMS (mean EDSS 6.6 pt, IQR 6-7.5) executed the mRPS that rates the quality of movement patterns and compensations during reach to grasp tasks. The content validity was determined by an expert panel based on observations of subjects performing the RPS. The reliability was based on five repetitions within one day, and between two days. For the concurrent validity, outcome measures at two levels of the International Classification of Functioning were correlated with the mRPS: Body Structure and Function level: Fugl-Meyer Assessment of the Upper Limb (FMA-UL), maximal isometric hand grip strength (HGS; Activity level: Action Research Arm Test (ARAT), Box and Blocks Test (BBT), Nine Hole Peg Test (NHPT) and Trunk Impairment Scale 2.0 (TIS 2.0) as well as perceived performance by the Manual Ability Measure-36 (MAM-36).
Scale modifications were made only on the ratings of the trunk displacement subscale. The mRPS had excellent agreement scores for within-session reliability (range of Kappa between 0.85 and 0.98) and moderate-to-excellent agreement scores for between-session reliability (K: 0.66-1.00). Regarding validity, the mRPS was highly correlated with the ARAT (rho=0.74, p < 0.001), followed by moderate correlations with trunk performance (TIS 2.0, rho= 0.61, p < 0.001), hand function (BBT: rho=0.64, p < 0.001; NHPT: rho=-0.61, p < 0.001) and perceived performance (MAM36 rho= 0.53, p < 0.001).
The mRPS is a reliable measurement tool to describe the movement pattern quality and motor compensations used during reaching in pwMS. Concerning concurrent validity, the mRPS is partially related to other measures of upper limb and trunk performance.
一种有效的、可靠的评估工具，用于描述伸手运动模式的质量，可以为多发性硬化症（MS）患者的运动表现缺陷提供有价值的见解。为评估中风患者的运动模式而开发的伸手表现量表（Reaching Performance Scale）是一种很有前途的评估 MS 患者运动模式的量表。然而，该量表在 MS 患者中的心理测量特性尚不清楚。
首先，探讨改良后的用于 MS 患者的伸手表现量表（mRPS）的内容效度。其次，探讨 mRPS 在 MS 患者中的心理测量特性（内部和外部测试的可靠性以及同时效度）。
45 例 MS 患者（平均 EDSS 6.6 分，IQR 6-7.5）执行 mRPS，该量表可评估伸手抓握任务中运动模式的质量和代偿情况。内容效度由专家小组根据观察患者执行 RPS 的情况来确定。可靠性基于一天内重复五次，以及两天之间的重复。为了进行同时效度研究，将国际功能、残疾和健康分类的两个水平的结果测量与 mRPS 进行相关分析：身体结构和功能水平：上肢 Fugl-Meyer 评估（FMA-UL），最大等长手握力（HGS）；活动水平：动作研究手臂测试（ARAT）、盒子和块测试（BBT）、九孔钉测试（NHPT）和躯干障碍量表 2.0（TIS 2.0）以及手动能力测量 36 项（MAM-36）的感知表现。
仅对躯干位移分量表的评分进行了量表修改。mRPS 具有极好的内部测试可靠性一致性评分（Kappa 值范围为 0.85 至 0.98）和中等至极好的外部测试可靠性一致性评分（K 值为 0.66-1.00）。关于有效性，mRPS 与 ARAT 高度相关（rho=0.74，p<0.001），其次与躯干表现（TIS 2.0，rho=0.61，p<0.001）、手部功能（BBT：rho=0.64，p<0.001；NHPT：rho=-0.61，p<0.001）和感知表现（MAM36，rho=0.53，p<0.001）中度相关。
mRPS 是一种可靠的测量工具，可用于描述 MS 患者伸手过程中的运动模式质量和运动代偿。关于同时效度，mRPS 与其他上肢和躯干表现的测量方法部分相关。
