  2. 'Symptoms other than RSI" refers to individuals considered to have 'symptoms of upper limbs unlikely to be related to RSI' (n = 102).
  3. The variable 'symptoms' refers to all subjects with symptoms of upper extremities (n = 222).
  4. To be considered as having 'RSI-like condition', positive responses to all 4 screening questions were required (n = 118).
