To evaluate the validity and reliability of the Spinal Mouse model to assess lumbar spine flexion.
For the validity study, patients with low-back pain underwent radiography to produce 2 lateral radiographs, first from the neutral position, and then with full trunk flexion. The correlation between mobility as assessed by radiography and the Spinal Mouse were evaluated by use of Spearman's correlation coefficient (SCC) for segmental mobility (L1-L2, L2-L3, L3-L4, L4-L5 and L5-S1) and global mobility (L1-L5 and L1-S1). Reliability was studied in healthy volunteers by the intraclass correlation coefficient (ICC).
A total of 20 patients (8 women) aged 41.6+/-8.6 (range 24-63), were included in the validity study. The SCC between radiography and Spinal Mouse measures were 0.55; 0.64; 0.69; 0.54; 0.19; 0.7; and 0.86 for flexion mobility of the L1-L2, L2-L3, L3-L4, L4-L5, L5-S1, L1-L5 and L1-S1, respectively. A total of 45 subjects aged 24.2+/-3.7 (range 20-29) were included for the reliability study. For intrarater reliability, the ICC was 0.84; 0.89; 0.96; 0.97; 0.63; 0.95 and 0.83 for the L1-L2, L2-L3, L3-L4, L4-L5, L5-S1, L5-S1, L1-L5 and L1-S1, respectively. For interrater reliability, the ICC was 0.75; 0.81; 0.79; 0.60; 0.83; 0.85, respectively.
The Spinal Mouse has acceptable metrological properties to assess segmental and global lumbar mobility during trunk flexion. Its metrological properties are not acceptable to assess mobility of L5-S1.
评估Spinal Mouse模型在评估腰椎前屈方面的有效性和可靠性。
在有效性研究中，对腰痛患者进行X线摄影，拍摄两张侧位X线片，首先是中立位，然后是躯干完全前屈位。通过使用Spearman相关系数（SCC）评估X线摄影和Spinal Mouse测量的节段性活动度（L1-L2、L2-L3、L3-L4、L4-L5和L5-S1）以及整体活动度（L1-L5和L1-S1）之间的相关性。通过组内相关系数（ICC）对健康志愿者进行可靠性研究。
有效性研究共纳入20例患者（8名女性），年龄41.6±8.6岁（范围24-63岁）。L1-L2、L2-L3、L3-L4、L4-L5、L5-S1、L1-L5和L1-S1节段前屈活动度的X线摄影与Spinal Mouse测量之间的SCC分别为0.55、0.64、0.69、0.54、0.19、0.7和0.86。可靠性研究共纳入45名年龄24.2±3.7岁（范围20-29岁）的受试者。对于同一评估者的可靠性，L1-L2、L2-L3、L3-L4、L4-L5、L5-S1、L5-S1、L1-L5和L1-S1的ICC分别为0.84、0.89、0.96、0.97、0.63、0.95和0.83。对于不同评估者的可靠性，ICC分别为0.75、0.81、0.79、0.60、0.83、0.85。
Spinal Mouse在评估躯干前屈过程中的节段性和整体腰椎活动度方面具有可接受的计量学特性。但其计量学特性在评估L5-S1活动度方面不可接受。
