title: Musculoskeletal health surveillance. Eight simple, self-administered tests to add to symptom registration: a preliminary report.
abstract: METHODS
  A population-based evaluation including cross-sectional comparisons of eight simple function tests (mobility and strength) and answers on questions concerning lifestyle factors, work environment, and health. The study population was randomly selected among people 35-45 years old.
  
  
  OBJECTIVE
  To construct a simple, self-administered surveillance system to test musculoskeletal function to be mailed to a sample population along with a questionnaire.
  
  
  BACKGROUND
  A surveillance system should be easy to use, detect treatable symptoms at an early stage, and detect change of function or symptoms.
  
  
  METHODS
  Questionnaires, which also contained instructions in performing the eight tests of musculoskeletal function, were sent to a randomly selected sample population. The questionnaire covered type and level of musculoskeletal problems, and lifestyle and occupational factors.
  
  
  RESULTS
  The questionnaire and the self-administered test were completed by 834 people. The test movements could be performed and the questions answered by the study population. The tests discriminated between those with and without moderate or severe problems. Performance of physically heavy work did not significantly correlate with the test results. The results of the physical function test discriminated significantly between those with different levels of fear of movement (odds ratio, 2.2) and the degree of current somatic distress (odds ratio, 5.9).
  
  
  CONCLUSIONS
  The test of physical function could be performed and the questionnaire completed by this randomly selected cohort, and the results discriminated significantly between groups.
