The literature shows that low back pain causes a reduced lumbar range of movement, affecting patients' proprioception and motor control. Nevertheless, studies have found that proprioception and motor control of the spine and posture are vague and individually expressed even in healthy young adults. This study aimed to investigate the standing posture and its modifications induced by an instinctive self-correction manoeuvre in subacute and chronic nonspecific low back pain (NSLBP) patients to clarify how NSLBP relates to body upright posture, proprioception, and motor control and how these are modified in patients compared to healthy young adults (121 healthy young adults: 57 females and 64 males). A cohort of 83 NSLBP patients (43 females, 40 males) were recruited in a cross-sectional observational study. Patients' entire body posture, including 3D spine shape reconstruction, was measured using a non-ionising 3D optoelectronic stereophotogrammetric approach. Thirteen quantitative biomechanical parameters describing the nature of body posture were computed. The statistical analysis was performed using multivariate methods. NSLBP patients did not present an altered proprioception and motor control ability compared to healthy young adults. Furthermore, as for healthy subjects, NSLBP patients could not focus and control their posture globally. Proprioception and motor control in natural erect standing are vague for most people regardless of gender and concurrent nonspecific low back pain. Self-correction manoeuvres improving body posture and spine shape must be learned with specific postural training focusing on the lumbar spine.
文献表明，腰痛会导致腰椎活动范围减小，影响患者的本体感觉和运动控制。然而，研究发现，即使在健康的年轻人中，脊柱和姿势的本体感觉和运动控制也不明确且因人而异。本研究旨在调查亚急性和慢性非特异性腰痛（NSLBP）患者在本能自我纠正动作下的站立姿势及其变化，以阐明NSLBP与身体直立姿势、本体感觉和运动控制之间的关系，以及与健康年轻人（121名健康年轻人：57名女性和64名男性）相比，这些在患者中是如何变化的。在一项横断面观察研究中招募了83名NSLBP患者（43名女性，40名男性）。使用非电离3D光电立体摄影测量法测量患者的全身姿势，包括3D脊柱形状重建。计算了13个描述身体姿势性质的定量生物力学参数。使用多变量方法进行统计分析。与健康年轻人相比，NSLBP患者的本体感觉和运动控制能力没有改变。此外，与健康受试者一样，NSLBP患者无法全局地集中和控制自己的姿势。无论性别和是否并发非特异性腰痛，大多数人在自然直立站立时的本体感觉和运动控制都不明确。改善身体姿势和脊柱形状的自我纠正动作必须通过专注于腰椎的特定姿势训练来学习。
