To assess feasibility, test-retest reliability and validity of the Four Square Step Test (FSST) in typically developed children (TD), and children with cerebral palsy (CP) and acquired brain injury (ABI).
30 TD children, 20 with CP and 12 with ABI participated in the study. The FSST while sitting and standing, the Timed Up and Go (TUG) and the balance subtest of the Bruininks-Oseretsky Test (BOT-2) were assessed. Each child attempted the FSST twice within 1 week. The scores for the FSST were assigned according to the original test: two successes in four trials, and according to a more lenient test, one success in four trials.
The original form of the FSST is not feasible for children with CP or ABI. In TD children the lenient version is feasible (93%) and has moderate stability (Interclass correlation, ICC = 0.723), with a significant, positive correlation with the TUG (r = 0.56). In children with CP the lenient test is feasible (80%), stable (r = 0.83) and negatively correlates with the BOT-2 (r=-0.69). In children with ABI the test is less feasible (67%) and neither stable nor valid.
The lenient form of the FSST is feasible, reliable and valid in TD children and children with CP.
评估四方步试验（FSST）在正常发育儿童（TD）、脑瘫（CP）儿童和获得性脑损伤（ABI）儿童中的可行性、重测信度和效度。
30名TD儿童、20名CP儿童和12名ABI儿童参与了该研究。评估了坐姿和站姿下的FSST、定时起立行走测试（TUG）以及布伦南克-奥塞雷茨基测试（BOT-2）的平衡子测试。每个儿童在1周内尝试两次FSST。FSST的评分根据原始测试标准：四次试验中有两次成功，以及根据更宽松的测试标准：四次试验中有一次成功。
FSST的原始形式对CP或ABI儿童不可行。在TD儿童中，宽松版本可行（93%）且具有中等稳定性（组内相关系数，ICC = 0.723），与TUG呈显著正相关（r = 0.56）。在CP儿童中，宽松测试可行（80%）、稳定（r = 0.83）且与BOT-2呈负相关（r = -0.69）。在ABI儿童中，该测试可行性较低（67%），既不稳定也无效。
FSST的宽松形式在TD儿童和CP儿童中可行、可靠且有效。
