Spastic Upperlimb in Hemiplegia

[physiobob]

Thanks Physiodude,
the thing is that upperlimb is relaxed after appling a susutained stretch, but once he makes a movement the tone increases, I guess tone fluctuates between changes in position.

You have provided your answer there. The person needs to work more in unbalanced sitting to get their trunk control better. The perhaps standing with enough support to keep the arm relaxed.
