2017年8月3日 · Ipsilateral Rotation and Contralateral Rotation: The term ipsilateral rotation is used to describe the motion created by a muscle that rotates the neck to the same side as where the muscle is located—in other words, a left-sided muscle that rotates the neck to the left side is performing ipsilateral rotation, as is a right-sided muscle that ...

2023年11月3日 · Rotatores muscles are a set of short muscles located laterally along the vertebral column, attaching between the transverse and spinous processes of thoracic vertebrae. As a result, the rotatores function as stabilizers, extensors and rotators of the spine.

Ipsilateral / Contralateral Rotation of the Head and Neck. Prev. Overview

Contralateral rotation of the head and cervical spine

Active cervical rotation usually results in a small amount of coupled lateral flexion and flexion/extension. The coupled movements of lateral flexion are usually greater than those in flexion/extension. Different studies have found that the average lateral flexion is either ipsilateral or contralateral to the direction of rotation. The movement ...

2000年10月18日 · The terms "ipsilateral and contralateral trunk rotation" refer almost exclusively to muscles' effects on trunk rotation. muscles are ipsilateral rotators if the muscles on the right rotate the trunk to the right.

2017年8月30日 · The term contralateral rotation is used to describe the motion created by a muscle that rotates the trunk to the opposite side from where it is located—in other words, a left-sided muscle that rotates the trunk to the right side is performing contralateral rotation, as is a right-sided muscle that rotates the trunk to the left side.

These discs act like shock absorbers throughout the spinal column to cushion the bones as the body moves. Ligaments hold the vertebrae in place, and tendons attach the muscles to the spinal column. The cervical spine is subjected to a range of extrinsic factors such as repetitive movements, whole-body vibrations and static load. [3]

2023年11月3日 · Bilateral contraction of multifidus produces extension of the vertebral column at all levels. When the muscles contract unilaterally, they produce ipsilateral lateral flexion and contralateral rotation of the vertebral column.

2022年12月21日 · Bilateral contraction of the muscle causes flexion of the neck (i.e. forward movement). Unilateral contraction, especially of the inferior oblique part, also results in weak lateral flexion (ipsilaterally) and contralateral rotation of the neck.
