title: Reference Values of Grip Strength Measured with a Jamar Dynamometer in 1526 Adults with Intellectual Disabilities and Compared to Adults without Intellectual Disability.
abstract: OBJECTIVE
  The aim of this study was to investigate grip strength in a large sample of people with intellectual disabilities, to establish reference values for adults with intellectual disabilities (ID) and compare it to adults without intellectual disability.
  
  
  METHODS
  This study analysed pooled baseline data from two independent studies for all 1526 adults with ID: Special Olympics Funfitness Spain (n = 801) and the Dutch cross-sectional study 'Healthy aging and intellectual disabilities' (n = 725).
  
  
  RESULTS
  The grip strength result of people with ID across gender and age subgroups is presented with CI95% values from higher 25.5-31.0 kg in male younger to lower 4.3-21.6 kg in female older.
  
  
  CONCLUSIONS
  This study is the first to present grip strength results of a large sample of people with ID from 20-90 years of age. This study provides reference values for people with ID for use in clinical practice.
