The Unidimensional Fatigue Impact Scale (U-FIS) is a disease-specific patient-reported outcome measure which measures the impact of multiple sclerosis related fatigue. [1] It is a 22-item unidimensional scale which is based on needs-based quality of life theory.
Fatigue. The Unidimensional Fatigue Impact Scale (U-FIS) was developed in 2009 by Galen Research primarily for the measurement of multiple sclerosis related fatigue. [60] It has been recommended for use in determining fatigue by an independent clinical research study [61] and translated into eight languages. [62] General Health.
Fatigue is the most frequently affirmed symptom of PCS included on the questionnaire, while double vision is the least affirmed. [7] Some other neuropsychological tests do not include fatigue as a symptom of PCS, giving the Rivermead Post-Concussion Symptoms Questionnaire an advantage in an "accurate" assessment of the condition.
The Borg RPE scale is a numerical scale that ranges from 6 to 20, [8] where 6 means "no exertion at all" and 20 means "maximal exertion." When a measurement is taken, a number is chosen from the following scale by an individual that best describes their perceived level of exertion during physical activity.
Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material.

Major changes in 2025 include Medicare Advantage plans and a new $2,000 out-of-pocket max under Part D, eliminating "donut hole" coverage gap.
Rainflow counting identifies the closed cycles in a stress-strain curve. The rainflow-counting algorithm is used in calculating the fatigue life of a component in order to convert a loading sequence of varying stress into a set of constant amplitude stress reversals with equivalent fatigue damage.
Paris' law (also known as the Paris–Erdogan equation) is a crack growth equation that gives the rate of growth of a fatigue crack. The stress intensity factor K {\displaystyle K} characterises the load around a crack tip and the rate of crack growth is experimentally shown to be a function of the range of stress intensity Δ K {\displaystyle ...
