BACKGROUND/AIM: The functional Tactile Object Recognition Test (fTORT) is a measure of haptic object recognition capacity recently adapted for use with children with neurological impairment. The current study aimed to investigate preliminary evidence of construct validity and responsiveness of the fTORT and its association with a measure of upper limb activity.
A cross-sectional study of 28 children with spastic hemiplegic cerebral palsy (CP) (mean age 10 years 8 months; SD two years four months; 16 male) and 39 typically developing (TD) children (mean age 11 years; SD two years nine months; 19 male) was utilised to investigate construct validity and association between measures. Sixteen children with CP (mean age 10 years 10 months; SD two years 8 months; 9 male) who were randomly allocated to either a treatment (n = 6) or control group (n = 10) were assessed at four time points to assess test responsiveness.
There was a very significant difference (P value <0.0001) indicating greater haptic object recognition ability for the TD group (n = 39; median: 40; range: 33-42) than the group with CP (n = 28; median: 32.5; range: 3-41). fTORT scores demonstrated a significant association with scores on the activity measure (Pearson's r: 0.68; P = 0.0001). There were no significant changes over time in fTORT scores (P = 0.22) and no significant difference between the treatment and control groups (P = 0.47).
The fTORT demonstrated preliminary construct validity, and was positively associated with an upper limb activity measure but scores did not change significantly following somatosensory training. This preliminary paper supports further research and future psychometric knowledge about the tool.
背景/目的：功能性触觉物体识别测试（fTORT）是一种用于测量触觉物体识别能力的测试，最近被应用于患有神经功能障碍的儿童。本研究旨在调查fTORT的结构效度和反应性的初步证据，以及它与上肢活动测量指标之间的关联。
采用横断面研究，纳入28例痉挛性偏瘫型脑瘫（CP）儿童（平均年龄10岁8个月；标准差2岁4个月；男性16例）和39例发育正常（TD）儿童（平均年龄11岁；标准差2岁9个月；男性19例），以研究结构效度及各项测量指标之间的关联。随机将16例CP儿童（平均年龄10岁10个月；标准差2岁8个月；男性9例）分为治疗组（n = 6）或对照组（n = 10），在四个时间点进行评估，以评估测试的反应性。
两组之间存在非常显著的差异（P值<0.0001），表明TD组（n = 39；中位数：40；范围：33 - 42）的触觉物体识别能力高于CP组（n = 28；中位数：32.5；范围：3 - 41）。fTORT评分与活动测量指标的得分之间存在显著关联（皮尔逊相关系数r：0.68；P = 0.0001）。fTORT评分随时间无显著变化（P = 0.22），治疗组和对照组之间也无显著差异（P = 0.47）。
fTORT显示出初步的结构效度，并且与上肢活动测量指标呈正相关，但体感训练后评分无显著变化。这篇初步研究报告支持对该工具进行进一步研究及未来建立心理测量学知识。
