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.
