The MMC-140 A/P Coil is designed for advanced clinical studies where double blinded research experiments are required.
The coil functions both as an active (A) coil and as a placebo (P) coil.
The coil has a symmetrical mechanical design and no labeling on the coil indicates the active or placebo side. Consequently, it is not possible for the operator to see or hear which side is used.
Built-in orientation switch to determine which side the operator shall direct towards the patient.
The coil is parabolic in shape to provide a powerful and focused stimulation.
To simulate stimulation on the placebo side a built-in vibrator generates mechanical vibrations synchronous with the stimulation pulse.
The use of all our A/P coils requires the Research Software USB-less to be installed on the MagPro.
