Parkinson’s disease-associated camptocormia: biopsy-confirmed focal myositis and treatment options

In this cohort of PD patients with camptocormia, muscle biopsy demonstrated local myositis in addition to myopathic changes in 64% of the cases. About two-thirds of these patients benefited from prednisolone therapy, as a symptomatic therapeutic option for muscle weakness. We recommend a histological work-up of the clinical diagnosis PD-associated camptocormia given that effective therapeutic options are available.
