Alterations in Muscle Tone ll

Alterations in Muscle Tone ll

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Spinal Cord: Cross-sectional Anatomy

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Central to the gray matter is...

Area of Science:

Biomechanics
Neuromuscular control
Pain science

Background:

Chronic non-specific low back pain (LBP) affects a significant portion of the population.
Understanding spinal movement characteristics is crucial for effective LBP management.
Current assessment methods may not fully capture subtle movement alterations.

Purpose of the Study:

To introduce and utilize a novel sensor strip method for assessing spinal movement.
To analyze spinal movement variability in individuals with chronic LBP during a functional task.
To investigate differences in movement patterns between LBP patients and healthy controls.

Main Methods:

17 chronic non-specific LBP subjects and 17 controls performed repetitive lifting.
Spinal movement was captured using a novel sensor strip with 12 angle sensors.
Recurrence quantification analysis evaluated the structure of spinal angle variability.

Main Results:

No significant mechanical differences were observed in task performance between groups.
LBP subjects reported increased pain, but task-related spinal movement remained similar.
A significantly higher percentage of determinism in accessory spinal movement was found in the LBP group.

Conclusions:

The variability structure of spinal movement is demonstrably different in individuals with chronic LBP.
Increased determinism in accessory spinal movement may serve as a valuable indicator of LBP-related impairment.
This measure holds potential for monitoring rehabilitation progress in LBP patients.
