title: [Timed up and go test for fingers in the form of the 20 cents test. Psychometric criteria of a simple performance test of fine motor skills].
abstract: BACKGROUND
  Although many activities depend on intact fine motor skills no standardized assessment has been broadly established. The 20 cents test (20-C-T) was developed in 2009 and takes less than 5 mins. The quality criteria were investigated within the framework of this study.
  
  
  METHODS
  A total of 300 geriatric patients participated in the study. The classification of occupational therapists based on standardized anamnesis and clinical examination served as the gold standard. Physiotherapists blinded to the study particulars applied the 20-C-T.
  
  
  RESULTS
  Every fourth patient suffered from deficits in fine motor skills relevant to everyday life. The 20-C-T correlated with the clinical severity level and was also feasible for patients with intermediate impairment of cognition or vision. Handedness, age and sex were without significant influence. Intrarater and interrater reliability were good.
  
  
  CONCLUSIONS
  Standardized testing of fine motor skills should be included in geriatric screening and basic assessment. The quality criteria of the 20-C-T show that it can be used for this purpose. Further diagnostic steps are recommended whenever a geriatric patient needs more than 40 s for the task.
