Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.3K
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...

Bone Disorders01:29

Bone Disorders

4.2K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Rolling Resistance01:21

Rolling Resistance

388
When a solid cylinder rolls steadily on a rigid surface, the normal force applied by the surface on the cylinder is perpendicular to the tangent at the contact point. However, since no materials are entirely rigid, the surface's reaction to the cylinder involves a range of normal pressures.
For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down...

The Functions of the Skeletal System01:22

The Functions of the Skeletal System

4.9K
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...

Dry Friction01:30

Dry Friction

516
Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible.
To illustrate this concept, imagine a wooden crate resting on a rough, non-uniform horizontal surface. When an external force is applied to...

Summary

Tyre manufacturing workers frequently experience work-related musculoskeletal disorders (WRMSDs), particularly low back pain. However, hamstring tightness and back muscle endurance did not correlate with this pain in the study.

Area of Science:

  • Occupational Health
  • Ergonomics
  • Musculoskeletal Disorders

Background:

  • Tyre manufacturing involves repetitive tasks like lifting and awkward postures, increasing risk for WRMSDs.
  • Workers in this industry face potential for elevated arm postures, heavy lifting, and trunk movements.

Purpose of the Study:

  • To evaluate the prevalence and risk factors of WRMSDs among tyre manufacturing employees.
  • Assessing musculoskeletal health in a high-risk industrial setting.

Main Methods:

  • Observational study of 99 tyre workers, excluding those with recent trauma or surgery.
  • Utilized the Nordic questionnaire, REBA analysis, hamstring flexibility (AKE test), and back extensor endurance (Sorenson test).

Main Results:

  • Low back pain (36%) was the most common complaint, followed by shoulder and neck pain.
  • REBA analysis indicated medium risk for TBR and PCR workers; hamstring tightness was prevalent.
  • No statistical relationship was found between hamstring tightness, back muscle endurance, and low back pain (P > 0.05).

Conclusions:

  • Tyre workers exhibit multi-joint musculoskeletal involvement, with low back pain being a primary concern.
  • Despite common hamstring tightness and reduced back muscle endurance, these factors were not significantly linked to low back pain in this cohort.
