Fibromyalgia

Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive difficulties often called "fibro fog." It affects approximately 2-4% of the population, predominantly women, and is considered an invisible disability because symptoms are not externally apparent. In accessibility contexts, fibromyalgia is relevant because it can significantly affect a person's ability to use standard input devices, sustain repetitive motions like typing or mouse use, and maintain concentration over extended periods. Accommodations may include ergonomic equipment, flexible scheduling, and customized assistive devices such as adapted grips or voice input.
