Neuromuscular disorders affect the neuromuscular system. They can cause problems with the nerves that control your muscles, your muscles, and communication between your nerves and muscles.
In motor power and tone, it is important to examine not only individual muscles but also functional groups. When patients complain of weakness, they often fail to distinguish between true loss of muscle power and difﬁculties due to pain or instability.
Nerve conduction studies and needle electromyography have an important role in the investigation of peripheral nerve and muscle disorders. Motor neuron disease affects both cortical motor neurons and anterior horn cells.
