Introduction[edit | edit source]

Contractures are generally myogenic and can mimic cramps. Often described by patients as exertional muscle stiffness or muscle cramping after arbitrary movement such as lifting heavy objects for more than a few seconds or after repetitive movements. Stretching the affected muscle during a contracture does not provide relief, and contractures generally last longer than muscle cramps. Painful contractures are prominent in metabolic myopathies such as McArdle disease, glycogenosis type V.[1] [2]

Definitions[edit | edit source]

Contractures are defined as shortenings of the muscle resulting in an inability of the muscle to relax normally.[1]
