Describe what is indicated by a 0/5 through 5/5 on muscle strength testing.
0/5: absent; no contraction detected.
1/5: trace; slight contraction detected.
2/5: weak; movement with gravity eliminated.
3/5: fair; movement against gravity.
4/5: good; movement against gravity with some resistance.
5/5: normal; movement against gravity with full resistance.
Describe what is indicated by a 0/4-4/4 on DTR testing.
0/4: absent; lower motor neuron (LMN) injury.
1/4: diminished; normal/LMN.
2/4: normal; normal.
3/4: brisk with unsustained clonus; normal/UMN.
4/4: brisk, sustained clonus; UMN.
