摘要

背景:脊柱操作已被证明可以影响肌肉活动、姿势和疼痛。到目前为止,还没有研究调查坐着时操作对生物力学因素的影响。因此,本研究的目的是调查腰椎操作对躯干肌肉激活、脊柱姿势和运动的直接影响,以及无症状成年人在长时间办公室坐着时短暂疼痛的感知评分。方法:招募20名健康成人进行单一实验,包括标准化的办公室坐姿/数据输入方案(总共120分钟,每40分钟3次)。数据收集于2012年7月至8月。第一个组(基线)之后紧接着是两个实验组。在每个实验块开始之前,参与者被转移到治疗基座并侧躺(右侧朝下),并随机呈现针对L4/L5的控制或高速低幅度推力。在整个坐姿试验中,记录了肌肉活动、脊柱姿势和脊柱运动的连续测量。用视觉模拟量表每隔10分钟测量一次瞬时疼痛感(包括随机运动前后)。结果:在脊柱或骨盆姿势或知觉背部疼痛后,操作或控制操作均无显著差异。与基线组和后对照组相比,在操作组中发现肌肉活动明显减少,腰椎角度增加。结论:脊柱操作似乎不会对健康成人的脊柱或骨盆姿势产生直接影响,但确实会减少肌肉活动并增加坐姿时脊柱的运动。未来的工作应该在更大的人群中重复这项研究。对于那些在工作日接受操纵或活动的上班族来说,在长时间坐着时,肌肉活动减少和脊柱活动增加的影响可能是值得探讨的。

The effect of lumbar spinal manipulation on biomechanical factors and perceived transient pain during prolonged sitting: a laboratory-controlled cross-sectional study.

Background: Spinal manipulation has been shown to affect muscle activity, posture, and pain. To date, no studies have examined the effect of manipulation on biomechanical factors during sitting. Therefore, the purpose of this study was to investigate the immediate effect of lumbar spinal manipulation on trunk muscle activation, spine posture and movements, and perceived ratings of transient pain in asymptomatic adults during prolonged office sitting.

Methods: Twenty healthy adults were recruited for a single laboratory session that included a standardized office sitting/data entry protocol (120 min total, 3 blocks of 40 min). Data were collected between July and August 2012. The first block (baseline) was immediately followed by two experimental blocks. Prior to the start of each experimental block, participants were transferred to a therapy plinth and placed side lying (right side down), and a random presentation of either a control or high velocity low amplitude thrust directed at L4/L5 was delivered. Continuous measures of muscle activity, spine posture, and spine movements were recorded throughout the sitting trials. Perceived transient pain was measured by visual analogue scale at 10-min intervals (including immediately before and after the randomized maneuvers).

Results: There were no significant differences in spine or pelvic posture or perceived back pain following either the manipulation or control maneuvers. Significantly reduced muscle activity and increased shifts of the lumbar spine angle were identified in the block following manipulation compared to both baseline and post control blocks.

Conclusions: Spinal manipulation does not appear to have an immediate impact on spine or pelvic posture in healthy adults but does appear to reduce muscle activity and increase spine movement during sitting. Future work should replicate this study with a larger population in a field setting. It may be worthwhile to explore the implication of reduced muscle activation and increased spine movements during prolonged sitting for office workers that receive manipulations or mobilizations during their workday.

期刊介绍: Chiropractic & Manual Therapies publishes manuscripts on all aspects of evidence-based information that is clinically relevant to chiropractors, manual therapists and related health care professionals. Chiropractic & Manual Therapies is an open access journal that aims to provide chiropractors, manual therapists and related health professionals with clinically relevant, evidence-based information. Chiropractic and other manual therapies share a relatively broad diagnostic practice and treatment scope, emphasizing the structure and function of the body''s musculoskeletal framework (especially the spine). The practices of chiropractic and manual therapies are closely associated with treatments including manipulation, which is a key intervention. The range of services provided can also include massage, mobilisation, physical therapies, dry needling, lifestyle and dietary counselling, plus a variety of other associated therapeutic and rehabilitation approaches. Chiropractic & Manual Therapies continues to serve as a critical resource in this field, and as an open access publication, is more readily available to practitioners, researchers and clinicians worldwide.
