The scale was originally introduced in 1957 by Dr. John Rankin of
Interobserver reliability of the mRS can be improved by using a structured questionnaire during the interview process[1][8] and by having raters undergo a multimedia training process.[9] The multimedia mRS training system which was developed by Prof. K. Lees' group at the University of Glasgow is available online. The mRS is frequently criticized for its subjective nature which is viewed as skewing results, but is used throughout hospital systems to assess rehabilitation needs and outpatient course. These criticisms were addressed by researchers creating structured interviews which ask simple questions both the patient and/or the caregiver can respond to.[1][10]
More recently, several tools have been developed to more systematically determine the mRS, including the mRS-SI,[11] the RFA,[2] and the mRS-9Q.[12] The mRS-9Q is in the public domain and free web calculators are available at modifiedrankin.com and mdcalc.com.
