  • Anti-estrogen medication within the last 6 months
  • Oral, intramuscular or intraarticular steroid within the last 3 months
  • Intraarticular hyaluronan to a hand joint within the last 6 months
  • Initiation of new oral analgesia within the last 4 weeks
  • Initiation of glucosamine, chondroitin, hand exercises or other relevant non- pharmacological therapy within the last 6 weeks
