Hi there,
You don't say how long your patient is post injury or if he has any return of voluntary muscle power. Re: electrical stimulation I have found it to be quite useful in tone reduction. Two approaches can be used - either treating agonist/antagonist at 35Hz(alternating) or 10Hz on spastic muscle and 40Hz on antagonist. I would use the latter if he has some degree of return even if masked by the spasticity. Also I would use a lot ofBobath techniques. Addressing the trunk with a lot of rotational and contrarotational mobilizations is also very useful for trunk reduction. Good luck. Oonagh
