Effects of exogenous factors on spatial accuracy in neurosurgery

The study aimed to assess the effect of exogenous factors such as surgeon posture, surgical instrument length, fatigue after a night shift, exercise and caffeine consumption on the spatial accuracy of neurosurgical manipulations. For the evaluation and simulation of neurosurgical manipulations, a testing device developed by the authors was used. The experimental results were compared using nonparametric analysis (Wilcoxon test) and multivariate analysis, which was performed using mixed models. The results were considered statistically significant at p < 0.05. The study included 11 first-year neurosurgery residents who met the inclusion criteria. Hand support in the sitting position (Wilcoxon test p value = 0.0033), caffeine consumption (p = 0.0058) and the length of the microsurgical instrument (p = 0.0032) had statistically significant influences on the spatial accuracy of surgical manipulations (univariate analysis). The spatial accuracy did not significantly depend on the type of standing position (Wilcoxon test p value = 0.2860), whether the surgeon was standing/sitting (p = 0.1029), fatigue following a night shift (p = 0.3281), or physical exertion prior to surgery (p = 0.2845).When conducting the multivariate analysis, the spatial accuracy significantly depended on the test subject (p < 0.0001), the use of support during the test (p = 0.0001), and the length of the microsurgical instrument (p = 0.0397). To increase the spatial accuracy of microsurgical manipulations, hand support and shorter tools should be used. Caffeine consumption in high doses should also be avoided prior to surgery.     

朱氏一指禅推法联合电针治疗膝骨关节炎临床疗效观察

目的:对比朱氏一指禅推法联合电针与单纯电针治疗膝骨关节炎的疗效差异。方法:将100例入组患者随机分为观察组和对照组,观察治疗前、治疗3周后及治疗后3个月随访VAS评分、WOMAC量表评分及测量膝关节活动度(ROM)。结果:两组患者治疗3周后及治疗后3个月随访,VAS和WOMAC量表评分及膝关节活动度均较治疗前明显改善,差异有统计学意义(P<0.01);VAS评分两组间差异无统计学意义(P>0.05),观察组改善WOMAC量表评分及膝关节活动度均优于对照组,差异有统计学意义(P<0.01);观察组总有效率均优于对照组,差异有统计学意义(P<0.05)。结论:朱氏一指禅推法联合电针对膝骨关节炎治疗具有显著作用,尤其在改善关节僵硬、躯体功能障碍及恢复膝关节活动度方面更为明显。     

中医治疗椎动脉型颈椎病研究进展

中医治疗椎动脉型颈椎病(cervical spondylosis of vertebral artery type,CSA)的主要方法有针灸治疗、中药治疗、手法治疗、综合疗法治疗等,其中针灸治疗包括电针治疗、其他针具治疗、灸法治疗;中药治疗包括中药内服治疗与中药外用治疗;手法治疗是采用不同推拿手法改善颈部肌肉紧张状态;综合疗法为电针、推拿、艾灸、中药熏蒸等相结合,为目前临床应用较多的治疗方法。目前,中医治疗CSA仍存在一些问题,比如研究样本量较小、无高质量、多中心随机对照研究,对照组设计欠科学、观察指标简单、无远期疗效观察等;大部分研究手法及中药治疗缺乏安全性、规范性探讨。因此未来临床研究本病应扩大样本量,采取多中心、随机对照模式,细化研究指标,并将安全性、规范性纳入研究范围,制定手法量学标准,为CAS的实际推广治疗本病方法提供依据。     

关节弹响与推拿所致“咔哒”声响的研究进展

关节弹响是人们熟悉却又不常注意的现象,有关节病症状的患者常将其作为主诉之一。临床医生在进行推拿手法时常出现的"咔哒"声响,多被认为是手法整复过程中的标志,但这与手法治疗成功、患者症状缓解的临床意义不尽相同,在临床操作中主要取决于医生的经验和习惯,使临床推拿手法具有一定的主观性。
