h-reflex

[Boazblake]

Anyone know / has made a H-reflex stimulator program with LabView?

I built a startle reflex stimulator but I do not know what  the H-reflex is.  Please describe your requirements in more detail.

What kind of output does the program need to generate? What kind of equipment does the program communicate with? Do you need to measure a response?  What kind? How?

I want to stimulate a peripheral nerve  - the Post' tibial nerve in the popliteal fossa.

I will be measuring the response of the  solues muscle via EMG.

I want to use a ramp protocol to stimulate the muscle (output can be in either mV or mA):

1ms Pulse width, at 0.2 Hz

The intensity starts at 0 and goes up in 0.2 increments, until I want to stop it, based on the EMG response that I see.

Thank you. That makes it quite clear.

I suggest that you look at standard medical/physiological equipment and seek devices which can be controlled from an external computer.  Creating the circuits along with the isolation and safety systems to do it yourself is a substantial task.  Once you have selected suitable equipment, then you can determine how it communicates with the computer and choose the adapters and software necessary to do the controls.
