Neuralgic amyotrophy of Parsonage and Turner. Which nerves are most frequently involved in daily practice? Data from 355 patients

Joint Bone SpinePublished Retrospective cohort study

Authors' conclusion

The clinical patterns of NAPT in ambulatory care thorough an EDX consultation have showed that unique mononeuropathy (UMN) are more frequent than MMN, what results in milder cases; and that five nerves lesions are more frequent and more suggestive of NAPT.
