MRC scale

MRC scale

(1) MRC breathlessness scale, MRC dyspnea. A clinical tool estimating the disability caused by dyspnea, which serves as a simple index of disease severity and extent in patients with idiopathic pulmonary fibrosis (IPF); its relationship with other common measures is not evaluated.

MRC dyspnea scale
1.  Not troubled by breathlessness except on strenuous exercise.
2.  Short of breath when hurrying or walking up a slight hill.
3.  Walks slower than peers on level ground due to dyspnea, or must to stop for breath when walking at own pace.
4.  Stops for breath after walking about 100m or after a few minutes on level ground.
5.  Too breathless to leave the house, or breathless when dressing or undressing.

(2) A system developed by the Medical Research Council (UK) for testing muscle strength, in which the strength of 18 different muscle groups are evaluated and given a value of 1 to 5 (maximum MRS score, 90).

MRC Muscle Strength Scale
0.  No movement is seen.
1.  Only a trace of movement is seen or felt in the muscle; fasciculation is seen in the muscle.
2.  Muscle can move only if the resistance of gravity is removed—e. g., elbow can be fully flexed only if the arm is maintained in a horizontal plane.
3.  Joint can be moved against gravity without resistance. As an example, the elbow can be moved from full extension to full flexion starting with the arm hanging down at the side.
4.  Muscle strength is reduced but muscle contraction can still move joint against resistance.
5.  Muscle contracts normally against full resistance.

Motor power was at grade 0/5 on the MRC scale. There was no nuchal rigidity.
Motor power on the right side was at grade 1/5, and 2/5 on the left side on the MRC scale. The remainder of the examination was unchanged.
Detailed neurological examination revealed weakness in hip flexion and extension (1/5 on the Medical Research Council [MRC] scale) with complete paralysis in knee flexion and extension (0/5 on the MRC scale) and ankle plantar and dorsiflexion (0/5 on the MRC scale).
The distribution of breathlessness severity as rated by the MRC scale consisted of 9 asthma patients at grade 0 (no breathlessness except during intense exertion), 14 at grade 1 (breathlessness during rapid walking or while walking uphill), 4 at grade 2 (stop while walking for 15 minutes on a level surface), 4 at grade 3 (stop while walking for a few minutes on a level surface), 5 at grade 4 (breathlessness while dressing or undressing).
The distribution of dyspnea severity as rated by the MRC scale was 4 COPD patients at grade 0, 3 at gl, 5 at g2, 5 at g3, and 2 at g4.
After three months of treatment it had increased considerably (Mean 4.760.43) .Maximum improvement was achieved after three months in muscle strength from 2.360.49 to 4.760.43 which is almost closer to 5 and showed normal Muscle strength according to MRC scale. Repeated measurement ANOVA was applied to compare mean muscle strength of affected side with in groups over different time periods [pless than 0.0001] (Table and Figure).
Two-point discrimination (2-PD), Semmes-Weinstein monofilament test (SW test) and power of involved muscles, and MRC scale were recorded.
MRC scale was 2 or less than 2 in 85% of patients in study group compared to 60% in control group (Table 6).
At the beginning and end of the rehabilitation, the chronic dyspnea during the DLA was quantified with the MRC scale.
(3-5) For VMT, the modified MRC scale (0-5) is a reliable method for grading muscle strength.
The results of his strength (MRC scale) and proprioception assessment at this point are shown in tables one and two.
Muscle strength loss was evaluated using MRC scale. Patients were evaluated and were divided into two groups: MRC score 2/5 or below, and MRC score of 3/5 or above (Table).
