This sounds like something that you read in an exam form or diagnostic report. ?What is being described is either active range of motion in the neck or passive range of motion in the neck. ?Active range of motion meaning how far you can flex or turn you neck yourself, passive range of motion meaning how far can the doctor move your neck. ?
Forward flexion meaning how far can your head move forward in degrees as you bring your chin to your chest. ?Extension meaning how far can you bring your head back like you are looking at the ceiling. ?Rotation meaning how far can you turn your head to the right or the left. ?Side ending, lateral bending, or lateral flexion meaning how far could you bend you head to the right or left side, as if you were bringing your ear toward your shoulder.
There are different "normal" values for active versus passive. ?And in fact there are different values for active or passive amongst many different textbooks. ?It sounds like "side bending" range of motion is reduced when bending to the right when compared to the left. ?It also sounds like "cervical rotation" is reduced when turning to the left when compared to the right.?
Reduced cervical range of motion is an indicator of some kind of neck dysfunction that is probably musculoskeletal. ?What that dysfunction is requires a complete history & examination that may include the addition of special tests like x-rays, MRI, CT, &/or EMG. ?You should seek the advice of your health-care professional to determine what this means in the context of a complete examination. ?From there you can discuss with your health-care professional how best to treat your problem.
The cervical spine, or neck region of the vertebral column, is capable of the most movement due to its anatomy and structure. It consists of seven vertebrae that allow for a wide range of motion, including flexion, extension, rotation, and lateral bending.
Forward bending or flexion, backward bending or extension. Side to side bending or lateral flexion and rotation.
Cervical radiculitius can be caused by a neck injury but, is not always associated with one. It is caused by an impact to the neck OR repeated bending of the neck. I have it and all of a sudden I woke up with my neck sideways and extreme nerve pain in my right arm. Hope this helps.
The flexor muscles are used when bending forward at the waist. The flexor muscles are located in the cervical and lumbar spine.
The neck contains several types of joints, including the atlas and axis vertebrae which form the atlantoaxial joint allowing for rotation and nodding movements, as well as synovial joints between the cervical vertebrae that allow for flexion, extension, and lateral bending. Additionally, there are joints between the sternocleidomastoid muscles and the skull which allow for head rotation and tilting movements.
The kind of synovial joint form is the hinge joint, because of its primary uniaxial range of movement (as in shaking your head "yes") There is also a small amount of side to side bending which can be done, and rotation is possible at this joint.
In addition to simple flexion (bending) and extension (straightening) movements, the knee joint is designed to allow for rotation, gliding, and rolling movements.
Your vertebrae in the neck region, known as the cervical spine, allow for a wide range of motion when you move your head. They work together to enable movements such as tilting, rotation, and bending of the head. The vertebrae are cushioned by discs to prevent friction and absorb shock during these movements.
Knee extension is a strength exercise that primarily targets the quadriceps muscle at the front of the thigh. It is commonly performed using a leg extension machine or with resistance bands. In contrast, triceps flexion and shoulder rotation are not standard strength exercises; triceps flexion typically refers to the action of bending the elbow, while shoulder rotation involves movement of the shoulder joint.
Usually cervical spondylosis is aggravated by extending (bending backwards), and side-bending of the head. If you have cervical nerve irritation associated with spondylosis, then you should avoid positions of your head that increase these symptoms. Yoga activities, therefore, should be tolerated as long as you are careful with the position of your head.
Some examples of movements that involve flexion and extension include bending and straightening the elbow, bending and straightening the knee, and bending forward and backward at the waist.
Flexion when you pull your forearm towards your body and extension when you extend it away from your body.
