Neuralgic amyotrophy (NA) is a disorder involving nerve pain and muscle wasting. In the Netherlands, NA is often referred to as 'neuralgic shoulder amyotrophy' or 'Parsonage-Turner syndrome'.
Episodes of severe pain
Neuralgic amyotrophy is characterized by episodes of severe pain in one or both shoulders and arms. After a few hours to several days, the pain is followed by weakness and wasting of the muscles in the affected area. It is caused by inflammation of the nerve plexus in the arm (brachial plexus brachialis), a branching network of intersecting nerves. The pain may last for a few weeks and is often unbearable. The muscle weakness causes difficulty with arm movements such as stretching, working above shoulder height, opening bottles or jar lids or holding a pen. Sometimes the shoulder blade sticks out from the back like a wing (scapula alata). Recovery of the nerves, and restoration of muscle strength and endurance, usually takes several months to a few years and is often incomplete. Many patients are left with chronic symptoms of pain and fatigue in the affected shoulder and arm.
Hereditary or non-hereditary
Two forms of NA are known. The idiopathic form occurs about ten times more often than the hereditary form. read moreHereditary or non-hereditary
Two forms of NA are known:
- Hereditary NA (hereditary neuralgic amyotrophy or HNA).
- Non-hereditary NA (idiopathic neuralgic amyotrophy, Parsonage-Turner or INA syndrome).
The idiopathic form occurs about ten times more often than the hereditary form. According to estimates, NA is diagnosed in about 17,000 people per year in the Netherlands.

to the treatment -
The Radboudumc has several consultation hours for patients with (possible) neuralgic amyotrophy or other injuries of the nerves in the shoulder and arm.

Examination of diaphragmatic paralysis in NA
Diaphragm paralysis may be suspected during the interview with the physician (anamnesis) about your symptoms, especially if neuralgic amyotrophy (NA) has been diagnosed with a sudden onset of shortness of breath when lying flat or bending over. This often occurs in combination with reduced physical condition and sleeping difficulty. to the examinationTeam Plexusclinic
Apart from these health care workers, a neurologist, a rehabilitation specialist, a physical therapist and an occupational therapist are often also present.
