Primary Outcome Measures:
  • Multi-site Pain Index [ Time Frame: single-visit ]

    Multiple Site Pain Index (MSPI) was developed by collating multiple pain descriptors into a single index. Pain descriptors used for developing this index were percent body area in pain, number of painful areas, span of painful areas, and Regional Pain Ratings (RPRs) which includes data on pain severity and pain continuity for 47 body regions.

    MSPI score ranged from 0 to 1; 0 representing no pain and 1 representing extreme continuous pain over entire body, except the head and face regions.
