5 = full resistance against gravity
4 = moderate resistance against gravity
3+ = minimal or slight resistance against gravity
3 = full AROM against gravity, no resistance
3- = more than 50% AROM against gravity, no resistance
2+ = full AROM in gravity-minimized position, SLIGHT RESISTANCE
2 = full AROM in gravity-minimized position, no resistance
2- = partial AROM in gravity-minimized position
1 = no AROM in gravity-minimized position but can palpate contraction
0 = no movement or muscle contraction in gravity-minimized position
