与腰痛（LBP）和手动材料处理（MMH）相关的预防和康复努力通常指向正确的技术。然而，呼吸控制可能是需要考虑的另一个因素。优化呼吸控制可以通过产生增加的腹内压来提供对脊柱的增加的节段控制。已经发现，呼吸控制不同的升降阶段的MMH与LBP的个人。然而，很少有人知道在降低部分的呼吸控制，即使它占30%的MMH任务。在这项研究中，患有LBP的个体（n= 32）和年龄匹配的健康个体（n= 30）将板条箱从桌子上降低到地板上四次，板条箱是空的，四次板条箱装载体重的25%。在降低任务期间的9个点确定肺中的体积量作为每个人的肺活量（VC）的百分比。LBP患者完成降低任务时，其肺容量（45.9%VC）显著高于健康同龄人（40.9%VC）。此外，随着年龄的增长，LBP患者的%VC显着增加。此外，%VC显著增加，以响应降低负载时引入的机械挑战。这些研究结果支持呼吸控制和腰椎节段控制之间的理论联系，并提供初步证据支持康复努力，增加了对LBP患者呼吸控制的关注。
Preventative and rehabilitative efforts relative to low back pain (LBP) and manual material handling (MMH) are often directed toward proper technique. However, breath control may be an additional factor to consider. Optimizing breath control may provide increased segmental control of the spine through the production of increased intra-abdominal pressure. It has been found that breath control differs during the lifting phase of MMH for individuals with LBP. However, little is known about breath control during the lowering portion even though it accounts for 30% of MMH tasks. In this study, individuals with LBP (n= 32) and aged-matched healthy individuals (n= 30) lowered a crate from a table to the floor four times with the crate empty and four times with the crate loaded at 25% of body weight. The amount of volume in the lungs as a percentage of each individual’s vital capacity (VC) was identified at nine points during the lowering task. Individuals with LBP completed the lowering task with significantly more volume in their lungs (45.9% VC) than healthy peers (40.9% VC). Further, with increasing age %VC significantly increased in those with LBP. Moreover, %VC significantly increased in response to the mechanical challenges introduced when lowering a load. These findings support the theoretical link between breath control and lumbar segmental control and provide preliminary evidence supporting rehabilitative efforts which add a focus on breath control for those with LBP.
