Vertebral Column: Regions and Curvature01:16

Vertebral Column: Regions and Curvature

5.6K
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...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.5K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Burn Injuries01:22

Burn Injuries

3.7K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Muscles of the Vertebral Column01:27

Muscles of the Vertebral Column

2.7K
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...

General Case of Eccentric Axial Loading01:12

General Case of Eccentric Axial Loading

364
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...

Classification of Illness01:17

Classification of Illness

8.3K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Area of Science:

  • Biomedical Science
  • Psychology
  • Sociology

Background:

  • Low back pain (LBP) is a leading cause of disability globally.
  • The reasons for LBP chronicity after an acute episode are not fully understood.
  • Identifying predictive factors is crucial for targeted interventions.

Purpose of the Study:

  • To identify modifiable biological, psychological, social, and behavioral factors predicting LBP outcomes.
  • To compare these factors between individuals with and without acute LBP.
  • To analyze the temporal changes of these factors from LBP onset.

Main Methods:

  • Longitudinal cohort study design.
  • Inclusion of 133 acute LBP patients and 74 pain-free controls.
  • Biopsychosocial and behavioral data collected at baseline and 3-monthly intervals for up to 12 months.

Main Results:

  • Baseline characteristics were largely similar between participants who completed follow-up and those who did not.
  • Initial analyses provide insights into the transition from acute to chronic LBP.
  • Data collection included fortnightly pain and disability assessments.

Conclusions:

  • The study methodology is established for investigating acute-to-chronic LBP.
  • Findings will inform new treatment and prevention strategies for persistent LBP.
  • Further analysis of the cohort data is expected to yield significant clinical insights.
