Pain severity (a) and pain interference with daily activities (b) in adults with Morquio A according to wheelchair use/mobility level. Pain severity and pain interference were evaluated using the Brief Pain Inventory (BPI); 1 = no pain/no pain interference, 10 = worst pain ever/complete pain interference. Pain interference scores were unavailable for 2 of the 4 patients in the "no wheelchair" and for 3 of the 9 patients in the "always wheelchair" groups. Presented as mean score and standard error of the mean.
