Lumbar hyperlordosis is a condition that occurs when the lumbar region (lower back) experiences stress or extra weight and becomes arched more than normal, sometimes leading to muscle pain or spasms. It is a common postural position in which the natural curve of the lumbar region of the back is slightly or dramatically accentuated.
Two points are marked: 5 cm below and 10 cm above this point (for a total of 15 cm distance). Then the patient is asked to touch his/her toes while keeping the knees straight. If the distance of the two points do not increase by at least 5 cm (with the total distance greater than 20 cm), then this is a sign of restriction in the lumbar flexion. [1]
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis.
Furthermore, flexion and extension in the lumbal spine is the product of a combination of rotation and translation in the sagittal plane between each vertebra. [4] Ranges of segmental movements in the lumbar spine (White and Punjabi, 1990) are (in degrees): [5]
The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°. The nerves are primarily from the sacral spinal cord roots S1 and S2. Compression of S1 roots may result in weakness in plantarflexion; these nerves run from the lower back to the bottom of the foot. [citation needed]
Principle I: When the spine is in neutral, sidebending to one side will be accompanied by horizontal rotation to the opposite side. [2] This law is observed in type I somatic dysfunction, where more than one vertebra is out of alignment and cannot be returned to neutral by flexion or extension of the vertebrae. The involved group of vertebrae ...
MRI of the lumbar spine showing spinal stenosis Neurogenic claudication is one subtype of the clinical syndrome of lumbar spinal stenosis (LSS). [ 9 ] No gold standard diagnostic criteria currently exist, but evaluation and diagnosis is generally based on the patient history, physical exam, and medical imaging . [ 1 ]
Spinal posture is the position of the spine in the human body. It is debated what the optimal spinal posture is, [ 1 ] and whether poor spinal posture causes lower back pain . [ 2 ] Good spinal posture may help develop balance, strength and flexibility .
