There is a lack of conclusive information about the optimal dosage of physical therapy treatments in Spondylolisthesis (SPL) patients.
The present study attempted to evaluate the comparative effectiveness of two different doses in reaching similar clinical outcomes.
A retrospective cohort study of 64 consecutive patients admitted for physical therapy with symptomatic lumbar grade I SPL (42 ± 15years, 57% female) was conducted. At the end of the treatment, all participants were retrospectively assigned to one of two groups, receiving either 5-8 or 9-12 sessions (experimental or control group, respectively) of physical therapy treatments. The Prone Bridge Test (PBT) and the Supine Bridge Test (SBT) were used to measure muscular endurance.
The area under the ROC curve for the PBT was 0.64 (95% CI 0.45-0.83) and for the SBT was 0.57 (95% CI 0.33-0.80). The optimal cutoff points were 25.5s for the PBT and 55.0s for the SBT. Logistic regression revealed that PBT (OR = 1.062) was associated with SPL. The final regression model explained 77.4% (R = 0.341; p = 0.024) of the variability.
In this sample, the number of sessions required to achieve satisfactory outcomes ranged from 5 to 12. The clinical results of the subjects in the 5-8 sessions group were similar to the 9-12 sessions group. Individual's coping mechanisms could be considered in future studies to understand which patients will require more therapeutic sessions.
关于腰椎滑脱（SPL）患者物理治疗的最佳剂量，缺乏确凿的信息。
本研究试图评估两种不同剂量在达到相似临床结果方面的比较效果。
对64例因有症状的I级腰椎SPL接受物理治疗的连续患者进行回顾性队列研究（42±15岁，57%为女性）。在治疗结束时，所有参与者被回顾性地分为两组，分别接受5 - 8次或9 - 12次（分别为实验组或对照组）物理治疗。俯卧桥测试（PBT）和仰卧桥测试（SBT）用于测量肌肉耐力。
PBT的ROC曲线下面积为0.64（95%CI 0.45 - 0.83），SBT的为0.57（95%CI 0.33 - 0.80）。PBT的最佳截断点为25.5秒，SBT的为55.0秒。逻辑回归显示PBT（OR = 1.062）与SPL相关。最终回归模型解释了77.4%（R = 0.341；p = 0.024）的变异性。
在本样本中，达到满意结果所需的治疗次数为5至12次。5 - 8次治疗组受试者的临床结果与9 - 12次治疗组相似。未来研究可考虑个体的应对机制，以了解哪些患者需要更多的治疗疗程。
