Power (MRC) — 0 no contraction · 1 flicker · 2 movement with gravity eliminated ·
3 against gravity · 4 against resistance · 5 normal. The 4−, 4, 4+ subdivisions
grade slight, moderate and strong resistance respectively.
DTR — 0 absent · 1+ hypoactive · 2+ normal · 3+ brisk · 4+ clonic.
Tone — one arrow for mild, two for marked. ↓ hypotonia,
↑ hypertonia (spasticity or rigidity — specify in Remarks).
Cells are shaded by severity so a column reads at a glance, and the MRC sum at the
foot of each column adds the muscles graded in that visit only — compare it between
visits only when the same muscles were tested.
