Summary
The Fatigue Severity Scale (FSS) is a valid and reliable tool for measuring fatigue in stroke patients. While effective for stroke survivors, it does not differentiate their fatigue from orthopedic patients.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Psychometrics
Background:
- Post-stroke fatigue is common, impacting daily life, quality of life, and mortality.
- The Fatigue Severity Scale (FSS) is widely used but lacks extensive validation in stroke populations.
Purpose of the Study:
- To evaluate the psychometric properties of the Fatigue Severity Scale (FSS) in individuals who have experienced a stroke.
Main Methods:
- 46 stroke patients and 52 orthopedic controls underwent comprehensive assessments.
- Measures included the FSS, visual analog scale for fatigue (VAS), and SF-36 vitality subscale.
- FSS, VAS, and SF-36 were re-administered after 7 days for reliability testing.
Main Results:
- FSS demonstrated excellent internal consistency (Cronbach's alpha: 0.928) and good test-retest reliability (ICC: 0.742).
- Moderate correlation found between FSS and SF-36 vitality (r = -0.498).
- Weak correlations observed between FSS and Hospital Anxiety and Depression Scale (HADS) scores.
Conclusions:
- The Fatigue Severity Scale (FSS) is a valid and reliable instrument for assessing fatigue in stroke survivors.
- FSS cannot distinguish fatigue levels between stroke patients and orthopedic patients of similar demographics.

01:29Reliability and Validity
13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

838
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...

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

01:24Muscle Recovery and Fatigue
4.2K
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...

01:22Fatigue Strength of Concrete
565
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...

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
