Layers of Connective Tissue Proper01:21

Layers of Connective Tissue Proper

2.0K
Fascia, a thin layer of fibrous connective tissue, is distributed throughout the body. It demarcates and forms a supportive covering over skeletal muscles, bones, blood vessels, and organs. There are three main types of facia— superficial fascia, deep fascia, and subserous fascia. These are all present at different depths in the body. Fascia reduces the friction and permits muscles, joints, and organs to easily slide against each other, facilitating movement of the body and preventing...

Introduction to Fibroblasts01:09

Introduction to Fibroblasts

3.1K
Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...

Fibril-associated Collagen01:11

Fibril-associated Collagen

2.6K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

998
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...

Peripherally and Centrally Acting Muscle Relaxants: A Comparison01:09

Peripherally and Centrally Acting Muscle Relaxants: A Comparison

3.4K
Skeletal muscle relaxants can target the central nervous system [CNS] to reduce muscle tension or act directly at the neuromuscular junction to induce temporary paralysis. These two classes of muscle relaxants are called centrally acting muscle relaxants and peripherally acting muscle relaxants. They differ in their action, mechanism, administration route, and clinical uses.
Centrally acting muscle relaxants can be further divided into spasmolytic and antispasmodic drugs. Spasmolytic...

Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

2.2K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Summary
This summary is machine-generated.

Women with fibromyalgia (FM) can experience virtual bodily illusions in immersive virtual reality (VR). Embodiment strength correlated with body perception disturbances and inversely with FM symptom intensity, suggesting personalized VR interventions.

Area of Science:

  • Neuroscience
  • Psychology
  • Rehabilitation Medicine

Background:

  • Chronic pain, such as fibromyalgia (FM), significantly impacts body ownership and perception.
  • Virtual reality (VR) offers novel methods to explore altered bodily experiences.

Purpose of the Study:

  • To investigate the receptiveness of women with FM to bodily illusions in VR.
  • To identify factors modulating the experience of virtual embodiment in this population.

Main Methods:

  • Twenty patients with FM participated in two VR sessions, experiencing visible and invisible body illusions.
  • Sentiment analysis and linear mixed models were used to analyze embodiment and its correlates.

Main Results:

  • Patients with FM demonstrated virtual embodiment.
  • Embodiment strength was positively linked to body perception disturbances and negatively to FM symptom intensity.
  • Affective reactions and cognitive distortions influenced embodiment, with significant patient variability.

Conclusions:

  • Women with FM are receptive to virtual bodily illusions, indicating potential for VR-based therapeutic approaches.
  • The effectiveness of VR interventions is modulated by individual affective responses, cognitive distortions, and symptom severity.
  • Future VR interventions for FM should account for substantial inter-patient variability.
