The Roland- Morris Disability Questionnaire(RM-24) was initially available in 12 languages but now it is available in 36 languages. The RMDQ translations can also be used without the permission from either the authors or from journal Spine. If any other translations are done, they may be sent to any author (MR) with details of the process of translation, so that these translations can be included in the content of Spine website. Among the modifications proposed for RMDQ by various researchers, one modification was to change the questionnaire’s wording that is to change each statement’s terminal phrase from “ because of my back” to “because of my back or leg problem”. This change is more suited for sciatica patients and the modifications are very acceptable (Patrick etal., 1995). Stratford & Binkley (1997) have suggested that large number of items were made redundant and there could be improvement to the questionnaire by reducing the items to 18. Patrick et al.(1995) have removed 5 redundant items that are potential . They have suggested that there could be increase in responsiveness by additional of four more additional items which are connected to daily work, sexual function, expression of concern to other people, and the requirement to hold or rub the areas that hurt. Over all the modifications seem to give only minor improvement on original version. A group of international experts have suggested that more of the original version should be used as it is widely used in various countries. A modification was suggested by Underwood et al.(1999) which asked of each item of the RDQ on the no of days the patient was affected in the previous month. This version if not validated and it attempts to incorporate the time people are influenced by the back pain which often varies. But there was not much performance of it apart from the modification of the questionnaire of Von Korff(Underwood e tal. , 1999).
