How to Differentiate Myopathy from Neuropathy Clinically?
1.Myopathy usually proximal, neuropathy has distal weakness
2.Neuropathy may have concomitant sensory symptoms and signs where Myopathy is purely motor.
3.In Myopathy all reflexes preserved till late of the disease course,but in neuropathy reflexes lost early
4.Fasciculations may be present in neuropathy and in Myopathy it is usually absent
5.In neuropathy atrophy is present where in Myopathy no atrophy until late
6.Contracture may be present in Myopathy whereas absent in neuropathy
7.In Myopathy there may be accompanying cardiac dysfunction with dystrophies,whereas it is not a typical feature of Neuropathy.
