Myopathies are diseases of muscle.

Like neuropathies, myopathies are characterised by:

  • muscle weakness
  • muscle atrophy
  • the pattern of muscle weakness seen in myopathies is usually proximal and symmetrical - this compares with a distal, or nerve or root distribution seen in neuropathies.
  • tone normal or reduced
  • reflexes normal or reduced

Sensory loss is not seen in myopathies.
