Ashworth scale tests resistance to passive motion about a joint with varying degrees of velocity. Modified Ashworth Scale (Bohannon and Smith, 1987) has 1+ grading between grades 1 and 2. Modified Ashworth Scale (Ansari et.al., 2006) has been described here.
Mnemonic: Ashworth is a juggling clown
0 : 0 is nothing (normal muscle tone)
1 : 1stly he needs to CATCH the balls to juggle (slightly increased tone, CATCHES near end of ROM)
2 : Juggling 2 balls is EASY (markedly increased tone, CATCH in middle ROM, but affected part EASILY moved)
3 : Juggling 3 balls is DIFFICULT (considerable increased tone, DIFFICULT Passive ROM)
4 : Juggling 4 balls is IMPOSSIBLE (rigid in flexion and extension)
