Abstract: Objective To explore the rehabilitation and outcome of motor neuron syndrome and Sjögren's syndrome. Methods A patient with motor neuron syndrome and Sjögren's syndrome was reviewed. Results The patient expressed progressive quadriparesis and slurred speech. Electromyogramphy displayed upper and lower motor neuron damage. Sonography showed diffuse lesions in parotid gland and submandibular gland. Laboratory tests displayed markedly elevated levels of SSA and Ro52 antibodies. After a course of intravenous immunoglobulin (IVIG) and four weeks of comprehensive rehabilitation, the patient improved in terms of speech, muscle strength, balance, posture control and activities of daily living. She failed to achieve further improvement after another IVIG and glucocorticoid two months later, but fortunately her symptoms did not deteriorate. Conclusion The patient with motor neuron syndrome and Sjögren's syndrome might benefit from IVIG and appropriate rehabilitation.
