The weakness characteristic of patients with MG is not limited to muscles innervated by a single cranial nerve — a sign that points more toward a possible neuromuscular disorder such as MG.

Typically, extraocular muscle weakness is asymmetric in patients with MG. It usually pervades more than one extraocular muscle. However, muscle weakness is generally more symmetric in proximal limb muscles.

In addition, sensory examination and deep tendon reflexes are normal in patients with MG.
