SpineCor is a dynamic brace that showed good results in scoliosis treatment. But data suggest that its efficacy is reduced as curves magnitude increase, and no comparisons exist versus exercise alone. The objective of this double study is to compare the short term results of the SpineCor versus SEAS exercises and versus rigid SpoRT brace for AIS.
2 retrospective controlled studies. Population 1: 56 consecutive AIS patients (39 female; age 13±1, Cobb 21±4°; ATR 11±4°): 28 patients (19 females; age 13±1; TRACE 6; Cobb angle 22±4°; ATR 12±4°, Risser 0-3) treated by SpineCor 20/24 hours; 28 patients (20 females; age 13±1; TRACE 5; Cobb angle 20±4°; ATR 9±3°, Risser 0-3) treated by SEAS exercises. Population 2: 103 consecutive AIS patients from our prospective database (85 females; age 13±1, Cobb 24±5°; ATR 8±4°): 29 patients (19 females; age 13±1; TRACE 6; Cobb angle 22±5°; ATR 9±3°, Risser 0-3) treated by SpineCor 20/24 hours per day; 74 patients (66 females; age 13±1; TRACE 5; Cobb angle 25±4°; ATR 8±4°, Risser 0-3) treated by SPoRT Brace 18 to 23 hours per day. The short term results of treatment, both clinical and radiographic, were evaluated after 18 months.
N° of rigid brace prescribed, TRACE, Cobb angle (changes > ±5), ATR (changes > ±2).
Study 1: the N° of patients prescribed with a rigid brace was not significantly different in the 2 groups. TRACE was stable for SEAS while decreased for SpineCor (p<0.05). Considering the number of patients changed > ±5° Cobb in the SEAS Group we found 39.3% improved and 14.3% worsened vs 25% and 21.4% in SpineCor (NS); no differences for ATR. Study 2: Both the treatment showed to be effective in improving the TRACE. Considering the other parameters, the SPoRT brace seems to be slightly more effective than the SpineCor both for the Cobb angle and the ATR.
Short term results showed the SpineCor's efficacy to be between rigid brace and exercise for treatment efficacy for AIS.
SpineCor是一种动态支具，在脊柱侧弯治疗中显示出良好效果。但数据表明，随着侧弯度数增加其疗效会降低，且目前尚无与单纯锻炼的对比研究。本双盲研究的目的是比较SpineCor与SEAS锻炼以及与用于特发性脊柱侧弯（AIS）的刚性SpoRT支具的短期效果。
两项回顾性对照研究。群体1：56例连续的AIS患者（39例女性；年龄13±1岁，Cobb角21±4°；顶椎旋转度（ATR）11±4°）：28例患者（19例女性；年龄13±1岁；顶椎旋转度追踪（TRACE）6；Cobb角22±4°；ATR 12±4°，Risser征0 - 3）每天使用SpineCor 20/24小时；28例患者（20例女性；年龄13±1岁；TRACE 5；Cobb角20±4°；ATR 9±3°，Risser征0 - 3）进行SEAS锻炼。群体2：来自我们前瞻性数据库的103例连续的AIS患者（85例女性；年龄13±1岁，Cobb角24±5°；ATR 8±4°）：29例患者（19例女性；年龄13±1岁；TRACE 6；Cobb角22±5°；ATR 9±3°，Risser征0 - 3）每天使用SpineCor 20/24小时；74例患者（66例女性；年龄13±1岁；TRACE 5；Cobb角25±4°；ATR 8±4°，Risser征0 - 3）每天使用SPoRT支具18至23小时。18个月后评估治疗的短期临床和影像学效果。
开具的刚性支具数量、TRACE、Cobb角（变化>±5°）、ATR（变化>±2°）。
研究1：两组中开具刚性支具的患者数量无显著差异。SEAS组的TRACE稳定，而SpineCor组的TRACE降低（p<0.05）。考虑SEAS组中Cobb角变化>±5°的患者数量，我们发现改善的患者占39.3%，恶化的患者占14.3%，而SpineCor组分别为25%和21.4%（无统计学差异）；ATR无差异。研究2：两种治疗方法在改善TRACE方面均显示有效。考虑其他参数，对于Cobb角和ATR，SPoRT支具似乎比SpineCor稍有效。
短期结果表明，在治疗AIS的疗效方面，SpineCor的疗效介于刚性支具和锻炼之间。
