概括

腰部滚动可以帮助计算机用户保持直立的部姿势,可能减少部肌肉的紧张. 然而,它对姿势,肌肉负荷和长时间打字时的不适的整体影响是最小的.

科学领域:

人体工程学就是人体工程学.
生物力学生物力学
物理疗法物理治疗

背景情况:

长时间使用电脑可能会导致部症状,原因是部结构的机械负荷,通常与前进的头部姿势有关.
腰部滚动是一个潜在的工具,可以通过在计算机任务中改善部姿势来减轻这种负载.
物理治疗指南强调需要确定这种支持对部症状的影响.

研究的目的:

调查腰部滚动是否有助于保持直立的头部,部和干姿势.
评估腰部滚动对减轻长时间打字时围部肌肉负荷的影响.
为了评估腰部滚动对主观部不适的影响.

主要方法:

一个随机的交叉实验,有30名参与者经历了部症状.
进行了两次60分钟的打字:一次用腰部滚动,一次不用.
测量包括椎角 (CVA),椎角 (CCA),脊柱/骨对齐,肌肉活动和主观不适.

主要成果:

腰部滚动立即改善了脊角 (CVA) 和脊柱对齐.
在使用腰部卷轴时,在超过一半的打字时间内观察到CVA的显著差异.
没有发现头部,干部,脚姿势,肌肉活动或主观部不适的显著变化.

结论:

腰部卷可以在计算机工作时保持更直立的部姿势,尽管临床意义尚不确定.
使用腰部滚动对整体姿势,周围部肌肉负荷和主观部不适的影响是微不足道的.
可能需要进一步的研究来确定姿势改善的意义和潜在的长期益处.

Vertebral Column: Regions and Curvature

Vertebral Column: Regions and Curvature

The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Muscles that Move the Head

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Muscles of the Vertebral Column

Muscles of the Vertebral Column

The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

Herniated Intervertebral Disc l: Introduction

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
