METHODS: A longitudinal, randomized controlled trial design was conducted between September to October 2023. Fifty-five participants were randomized into a control group of deactivated ultrasound (n = 29) or treatment group of right sidelying lumbar SMT (n = 26). PPT, recorded at the right posterior superior iliac spine (PSIS), was documented for each participant in each group prior to intervention, immediately, and 30-minutes after. A repeated measures ANOVA, with a post-hoc Bonferroni adjustment, was used to assess within-group and between-group differences in PPT. The significance level was set at a < 0.05 a priori.
RESULTS: Statistically significant differences were found between the deactivated ultrasound and lumbar SMT groups immediately (p = .05) and 30-minutes (p = .02) following intervention. A significant difference in the lumbar SMT group was identified from baseline to immediately following (p < .001) and 30-minutes following (p < .001), but no differences between immediately following and 30-minutes following intervention (p = .10). The deactivated ultrasound group demonstrated a difference between baseline and immediately after intervention with a reduced PPT (p = .003), but no significant difference was found from baseline to 30-minutes (p = .11) or immediately after intervention to 30-minutes (p = 1.0).
CONCLUSIONS: A right sidelying lumbar manipulation increased PPT at the right PSIS immediately after that lasted to 30-minutes when compared to a deactivated ultrasound control group. Future studies should further explore beyond the immediate and short-term neurophysiological effects of lumbar SMT to validate these findings.
BACKGROUND: This study was retrospectively registered on 4 December 2023 in ClinicalTrials (database registration number NCT06156605).
方法:纵向,随机对照试验设计于2023年9月至10月进行.55名参与者被随机分为停用超声的对照组(n=29)或右侧腰SMT的治疗组(n=26)。PPT,记录在右髂后上棘(PSIS),在干预前记录了每组中的每个参与者,立即,30分钟后.重复测量方差分析,通过事后的Bonferroni调整,用于评估PPT的组内和组间差异。显著性水平预先设定为<0.05。
结果:在介入后立即(p=.05)和30分钟(p=.02)停用的超声和腰椎SMT组之间发现了统计学上的显着差异。腰椎SMT组从基线到紧接着(p<.001)和30分钟后(p<.001)发现了显着差异,但干预后立即和干预后30分钟之间没有差异(p=.10)。停用的超声组显示出基线和干预后立即减少的PPT之间的差异(p=.003),但从基线到30分钟(p=.11)或干预后立即到30分钟(p=1.0)无显著差异.
结论:与停用的超声对照组相比,右侧侧腰椎操作在持续30分钟后立即增加了右侧PSIS的PPT。未来的研究应进一步探索腰椎SMT的直接和短期神经生理效应,以验证这些发现。
背景:这项研究于2023年12月4日在ClinicalTrials(数据库注册号NCT06156605)中进行了回顾性注册。
