Muscle Recovery and Fatigue01:24

Muscle Recovery and Fatigue

3.6K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Fatigue01:21

Fatigue

531
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Fatigue Strength of Concrete01:22

Fatigue Strength of Concrete

393
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...

Summary
This summary is machine-generated.

Validated fatigue scales are lacking for inflammatory skin, neuropsychiatric, and medical disorders. This review found no fatigue scales with content validation, highlighting the urgent need for new measurement tools.

Area of Science:

  • Medical research
  • Clinical assessment
  • Psychometrics

Background:

  • Fatigue is a significant symptom in various chronic conditions.
  • Validated measurement tools are crucial for accurate data collection and patient assessment.
  • Existing fatigue scales may lack validation in specific patient populations, particularly dermatology.

Purpose of the Study:

  • To conduct a meta-review of existing fatigue scales.
  • To evaluate scales used in inflammatory conditions for potential application in dermatologic disorders.
  • To identify fatigue scales validated for dermatologic conditions.

Main Methods:

  • Systematic literature search of PubMed/MEDLINE and SCOPUS databases.
  • Adherence to PRISMA statement guidelines.
  • Assessment of identified fatigue scales based on measurement properties, including content validation.

Main Results:

  • Eight studies met eligibility criteria from 403 references.
  • Included unidimensional scales: Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), Brief Fatigue Inventory, Fatigue Severity Scale, Numerical Rating Scale - Fatigue, and Visual Analog Scale - Fatigue.
  • Included multidimensional scales: Checklist Individual Strength, Chalder Fatigue Scale, Multidimensional Assessment of Fatigue, Multidimensional Fatigue Inventory Scale, and Piper Fatigue Scale.
  • None of the reviewed scales demonstrated content validation, though FACIT-F was validated in psoriatic arthritis.

Conclusions:

  • There is a critical need for validated fatigue measurement tools in inflammatory skin, neuropsychiatric, and medical disorders.
  • Current fatigue scales lack sufficient content validation for broad application.
  • Further validation studies are urgently required for specific patient populations, especially in dermatology.
