To examine the validity and reliability of 3-Meter Backwalk Test (3MBWT) in children with Cerebral Palsy (CP).
Study included 55 children with CP with the mean age of 12.34 ± 3.78 years, at Expanded and Revised Gross Motor Functional Classification System (GMFCS-E&R) I and II levels. Intraclass Correlation Coefficient (ICC) was used for the intra-rater and inter-rater reliability of 3MBWT according to the GMFCS-E&R levels. MDC estimates were calculated using baseline data. Convergent validity of 3MBWT was evaluated with its correlation between the Timed Up and Down Stairs Test (TUDS), Pediatric Balance Scale (PBS), Timed Up and Go Test (TUG), Pediatric Reach Test (PRT), Four Square Step Test (FSST).
Intra-rater and inter-rater reliability of 3MBWT was determined excellent at GMFCS-E&R I (Intra-rater ICC = 0.981-0.987, inter-rater ICC = 0.982-0.993), and GMFCS-E&R II (ICC = 0.927-0.933, ICC = 0.954-0.968). Intra-rater MDC values for GMFCS-E&R I were 1.17-1.22 s (s); 1.40-1.42 s for GMFCS-E&R II. Inter-rater MDC values for GMFCS-E&R I were 1.00-1.28 s, and MDC values for GMFCS-E&R II were 1.08-1.22 s. There was strong correlation between 3MBWT and PBS, TUG, and FSST in GMFCS-E&R I, moderate correlation between 3MBWT and TUDS, strong correlation between BBS, moderate correlation between TUG, and strong correlation between FSST in GMFCS-E&R II (p < 0.05).
The 3MBWT was found to be valid and reliable in children with CP. According to the MDC results, small differences in CP children can be adequately detected with 3MBWT. The 3MBWT also may add some more information on to GMFCS (E&R) data for following the disease progression as well as rehabilitation responses.

探讨 3 米往返步行测试（3MBWT）在脑瘫儿童中的有效性和可靠性。
本研究纳入了 55 名脑瘫儿童，平均年龄为 12.34±3.78 岁，处于扩展和修订后的粗大运动功能分级系统（GMFCS-E&R）I 和 II 级。根据 GMFCS-E&R 水平，采用组内相关系数（ICC）评估 3MBWT 的内部观察者和外部观察者的可靠性。使用基线数据计算最小可检测差异（MDC）估计值。通过与计时上下楼梯测试（TUDS）、小儿平衡量表（PBS）、计时起立行走测试（TUG）、小儿伸手测试（PRT）、四方步测试（FSST）的相关性来评估 3MBWT 的收敛效度。
内部观察者和外部观察者的 3MBWT 在 GMFCS-E&R I（内部观察者 ICC=0.981-0.987，外部观察者 ICC=0.982-0.993）和 GMFCS-E&R II（ICC=0.927-0.933，ICC=0.954-0.968）的可靠性均为优。GMFCS-E&R I 的内部观察者 MDC 值为 1.17-1.22 秒（s），GMFCS-E&R II 的内部观察者 MDC 值为 1.40-1.42 秒。GMFCS-E&R I 的外部观察者 MDC 值为 1.00-1.28 秒，GMFCS-E&R II 的外部观察者 MDC 值为 1.08-1.22 秒。在 GMFCS-E&R I 中，3MBWT 与 PBS、TUG 和 FSST 之间存在强相关性，与 TUDS 之间存在中度相关性，在 GMFCS-E&R II 中，与 BBS 之间存在强相关性，与 TUG 之间存在中度相关性，与 FSST 之间存在强相关性（p<0.05）。
3MBWT 在脑瘫儿童中具有有效性和可靠性。根据 MDC 结果，3MBWT 可以充分检测脑瘫儿童的微小差异。3MBWT 还可以为 GMFCS（E&R）数据提供更多信息，以便跟踪疾病进展和康复反应。
