title: Musculoskeletal problems in Parkinson's disease: neglected issues.
abstract: BACKGROUND
  To identify the prevalence and clinical features of musculoskeletal problems in patients with Parkinson disease (PD) compared to controls.
  
  
  METHODS
  400 PD patients and 138 age- and sex-matched controls were interviewed by physicians about their musculoskeletal problems.
  
  
  RESULTS
  The prevalence of musculoskeletal problems was significantly higher in the PD group than in the control group (66.3% vs. 45.7%, P < 0.001). Commonly involved body sites were the low back, knee, and shoulder in that order. The low back was more frequently involved in the PD group than in the control group (44.3% vs. 24.6%, P < 0.001), and the shoulder tended to be more involved in the PD group than in the control group (15.0% vs. 8.7%, P = 0.061). However, the knee was similarly involved in both group (12.3% vs. 18.0%, P = 0.121). Among the past diagnoses associated with musculoskeletal problems, frozen shoulder, low back pain, osteoporosis and fracture were more common in the PD group than in the control group (P < 0.05). Older age, female, and a higher score on the Unified Parkinson's Disease Rating Scale I & II were associated with musculoskeletal problems in the PD group. Only 26.8% of the PD patients and 52.5% of the controls with musculoskeletal problems answered that their musculoskeletal problems were recovering. Furthermore, musculoskeletal problems in the PD group tended to receive less treatment than that of the control group (P = 0.052).
  
  
  CONCLUSIONS
  Musculoskeletal problems were more common in the PD group than in the controls. Furthermore, despite PD patients having a higher prevalence, they did not receive adequate treatment.
