Irrespective of limited evidence, not only traditional physiotherapy, but also a wide array of complementary methods are applied by patients with Parkinson's disease (PD). We evaluated the immediate and sustained effects of Qigong on motor and nonmotor symptoms of PD, using an add-on design. Fifty-six patients with different levels of disease severity (mean age/standard deviation [SD], 63.8/7.5 years; disease duration 5.8/4.2 years; 43 men [76%]) were recruited from the outpatient movement disorder clinic of the Department of Neurology, University of Bonn. We compared the progression of motor symptoms assessed by Unified Parkinson's Disease Rating Scale motor part (UPDRS-III) in the Qigong treatment group (n = 32) and a control group receiving no additional intervention (n = 24). Qigong exercises were applied as 90-minute weekly group instructions for 2 months, followed by a 2 months pause and a second 2-month treatment period. Assessments were carried out at baseline, 3, 6, and 12 months. More patients improved in the Qigong group than in the control group at 3 and 6 months (P = 0.0080 at 3 months and P = 0.0503 at 6 months; Fisher's exact test). At 12 months, there was a sustained difference between groups only when changes in UPDRS-III were related to baseline. Depression scores decreased in both groups, whereas the incidence of several nonmotor symptoms decreased in the treatment group only.

We analysed non-motor symptoms (NMS) related to autonomic dysfunction in 3414 patients with Parkinson's disease (PD) enrolled in the multicentre registry of the German Competence Network on PD. Orthostatic hypotension (> 20 mmHg systolic or > 10 mmHg diastolic) was reported for 10% of women and 11% of men, urinary incontinence for 22% of women and 21% of men, sexual dysfunction for 8% of women and 30% of men (50% of whom reported erectile dysfunction) and sleep disturbances for 43% of women and 35% of men. Autonomic symptoms occurred in a frequency similar to severe disabling dyskinesia which was reported for 16% of women and 11% of men. A logistic regression analyses with age, sex and disease duration as covariates revealed a significant correlation of orthostatic hypotension and urinary incontinence with age and disease duration whilst sexual dysfunction was related to age only. These observations suggests that the effects of the PD process and ageing contribute to non-levodopa responsive NMS. Sleep disturbances were more common in women and a correlation was found with disease duration only supporting the notion that sleep is specifically affected in PD.

We identified 221 patients with probable multiple system atrophy (MSA) among 4770 patients enrolled in the multicentre registry of the German Competence Network on Parkinson's disease (PD) according to the established consensus criteria to characterize their clinical presentation. Analyses of more than 100 recorded clinical items revealed several specifics: I) 50% of patients with probable MSA had asymmetry of symptoms at disease onset and tremor at rest was present in 25%; II) a positive response to levodopa was recorded in 51% of patients identified initially with severe autonomic failure and cerebellar ataxia; III) a positive family history was recorded in 11% (n = 23), two of these patients were identified with spinocerebellar ataxia type 3 (SCA3). Thus asymmetry of symptoms, tremor at rest and a positive response to levodopa are not as specific for idiopathic PD as believed previously. Patients with SCA3 may present with the clinical features of MSA.
