MRCP UK EXAMINATIONS

Detailed explanation-1: -The MRC scale of muscle strength uses a score of 0 to 5 to grade the power of a particular muscle group in relation to the movement of a single joint.

Detailed explanation-2: -1-flicker of contraction possible. 2-movement is possible when gravity is excluded. 3-movement is possible against gravity. 4-movement is possible against gravity + some resistance.

Detailed explanation-3: -For example, a grade of 4+ indicates that a muscle has a strength somewhere between 4 and 5. A 4-grade means that a muscle was near 4 but not that confidently. Muscle power grading is useful in localizing the lesion and to differentiate the groups of muscles affected so that treatment can be affected.
