Basic knowledge again, but I’ve noticed some interesting numbers used to grade motor power in some medical notes recently, so I thought a reminder would be useful:
5 normal power
4 moderate movement against resistance
4 plus – submaximal movement against resistance
4 minus – slight movement against resistance
3 movement is possible against gravity but not if any further resistance is added
2 movement is possible when gravity is excluded
1 flicker of contraction possible
0 complete paralysis / no movement
