To evaluate the reliability of the Motor Learning Strategies Rating Instrument (MLSRI-20) in gait-based, video-recorded physiotherapy interventions for children with cerebral palsy (CP).
Thirty videos of 18 children with CP, aged 6 to 17 years, participating in either traditional or Lokomat-based physiotherapy interventions were rated using the MLSRI-20. Physiotherapist raters provided general and item-specific feedback after rating each video, which was used when interpreting reliability results.
Both interrater and intrarater reliability of the MLSRI-20 total score was good. The interrater reliability intraclass correlation coefficient (ICC) was 0.78 with a 95% confidence interval (CI) of 0.53-0.89 and a coefficient of variation (CV) of 11.8%. The intrarater reliability ICC was 0.89 with a 95% CI of 0.76-0.95 and CV of 7.8%. Rater feedback identified task delineation and interpretation of therapist verbalizations as sources of interrater reliability-related scoring challenges.
The MLSRI-20 is a reliable tool for measuring the extent to which a physiotherapist uses motor learning strategies during a video-recorded intervention. These results have clinical and research implications for documenting and analyzing the motor learning content of physiotherapy interventions for children with CP.
The Motor Learning Strategies Rating Instrument (MLSRI-20) is reliable for use by trained physiotherapist raters. Measuring motor learning strategies can identify active 'ingredients' in physiotherapy interventions for children with cerebral palsy. The MLSRI-20 promotes a common language in motor learning.
评估运动学习策略评定量表（MLSRI-20）在基于步态的、视频记录的脑瘫儿童物理治疗干预中的可靠性。
30 个视频记录了 18 名 6 至 17 岁的脑瘫儿童，他们参与了传统或 Lokomat 为基础的物理治疗干预，使用 MLSRI-20 进行了评分。治疗师评分员在对每个视频进行评分后提供了一般和特定项目的反馈，这些反馈在解释可靠性结果时使用。
MLSRI-20 总分的组内和组间可靠性都很好。组间可靠性的组内相关系数（ICC）为 0.78，95%置信区间（CI）为 0.53-0.89，变异系数（CV）为 11.8%。组内可靠性的 ICC 为 0.89，95%CI 为 0.76-0.95，CV 为 7.8%。评分员的反馈确定了任务划定和治疗师言语解释作为组间可靠性相关评分挑战的来源。
MLSRI-20 是一种可靠的工具，用于测量治疗师在视频记录的干预过程中使用运动学习策略的程度。这些结果对记录和分析脑瘫儿童物理治疗干预的运动学习内容具有临床和研究意义。
运动学习策略评定量表（MLSRI-20）对于经过培训的物理治疗师评分员来说是可靠的。测量运动学习策略可以确定脑瘫儿童物理治疗干预中的活跃“成分”。MLSRI-20 促进了运动学习中的共同语言。
