Objective[edit | edit source]
The Medical Research Council (MRC) Muscle Scale, developed by the UK Medical Research Council, is a scale of measuring the power or strength produced by muscle contraction. The scale was originally described in the paper Aids to the Investigation of Peripheral Nerve Injuries (War Memorandum No. 7), released in 1943. Measurement is scored on a 0 to 5 scale, with 5 representing maximal strength.[1]
The Medical Research Council Sum-Score (MRC-SS) was developed in the late 1980s and first described by Kleyweg, Van Der Meché, and Schmitz (1991) as a tool for assessing and tracking general muscle strength in individuals with Guillian-Barré syndrome. Currently though, the MRC-SS is a tool commonly used to determine the presence of and/or track the development of Intensive Care Unit (ICU) Acquired Weakness.[2][3]
Intended Population[edit | edit source]
Originally developed for use with patients diagnosed with Guillian-Barré syndrome, including those who were considered bedbound or were receiving mechanical ventilation. Presently, MRC-SS is still used for patients who are bedbound or receiving mechanical ventilation, but its use has been expanded to the more general critical care and ICU populations.[2][3]
