Definition of amyotrophy in US English:



  • Muscular atrophy.

    • ‘Sensory neuropathies can be classified as distal symmetric polyneuropathy, focal neuropathy, and diabetic amyotrophy.’
    • ‘Diabetic amyotrophy, also known as femoral neuropathy or proximal motor neuropathy, usually is bilateral and frequently is associated with weight loss.’
    • ‘In addition, recent biopsy studies indicate that diabetic amyotrophy is due to microvasculitis in the lumbosacral plexus.’
    • ‘The disorder is characterized clinically by amyotrophy and segmented sensory loss and pathologically by cavitation of central parts of the spinal canal that results in changes in direction and freedom of flow of cerebral spinal fluid.’
    • ‘Neuralgic amyotrophy, also known as brachial plexus neuropathy, has an incidence of 1.64 per 100 000 people.’


Late 19th century: from a- ‘not’ + Greek mus, muo- ‘muscle’ + Greek trophē ‘nourishment’.
