title: Tango for treatment of motor and non-motor manifestations in Parkinson's disease: a randomized control study.
abstract: OBJECTIVE
  To determine effects of Argentine tango on motor and non-motor manifestations of Parkinson's disease.
  
  
  METHODS
  Randomized control trial.
  
  
  METHODS
  Forty patients with idiopathic Parkinson's disease.
  
  
  METHODS
  Movement disorder clinic and dance studio.
  
  
  METHODS
  Two randomized groups: group (N=18) with 24 partnered tango classes, and control self-directed exercise group (N=15).
  
  
  METHODS
  The primary outcome was overall motor severity. Secondary outcomes included other motor measures, balance, cognition, fatigue, apathy, depression and quality of life.
  
  
  RESULTS
  On the primary intention-to-treat analysis there was no difference in motor severity between groups MDS-UPDRS-3 (1.6 vs.1.2-point reduction, p=0.85). Patient-rated clinical global impression of change did not differ (p=0.33), however examiner rating improved in favor of tango (p=0.02). Mini-BESTest improved in the tango group compared to controls (0.7±2.2 vs. -2.7±5.9, p=0.032). Among individual items, tango improved in both simple TUG time (-1.3±1.6s vs. 0.1±2.3, p=0.042) and TUG Dual Task score (0.4±0.9 vs. -0.2±0.4, p=0.012), with borderline improvement in walk with pivot turns (0.2±0.5 vs. -0.1±0.5, p=0.066). MoCa (0.4±1.6 vs. -0.6±1.5, p=0.080) and FSS (-3.6±10.5 vs. 2.5±6.2, p=0.057) showed a non-significant trend toward improvement in the tango group. Tango participants found the activity more enjoyable (p<0.001) and felt more "overall" treatment satisfaction (p<0.001). We found no significant differences in other outcomes or adverse events.
  
  
  CONCLUSIONS
  Argentine tango can improve balance, and functional mobility, and may have modest benefits upon cognition and fatigue in Parkinson's disease. These findings must be confirmed in longer-term trials explicitly powered for cognition and fatigue.
