Association between 'worst pain' score and some interference with individual activities of daily living [36]. Fifty patients with HZ were asked to rate their level of pain on a scale from 0 (no pain) to 10 (pain as bad as you can imagine). Interference of pain with seven activities of daily living was measured by the Wisconsin Brief Pain Inventory (four of seven daily activities are shown). Some interference was defined as a score of ≥3. There is a clear correlation between increased pain intensity and greater interference with daily activities and the enjoyment of life. Approximately 20%-30% of those with moderate pain (score 4) reported that the pain affected their daily activities. At least 51% of those who experienced high levels of pain (score 9-10) reported that pain interfered with each activity. Adapted with permission from Lydick et al. [31].
