What is the Double Coil PMD70-pCool-SHAM?

The Double Coil PMD70-pCool-SHAM is MAG & More’s dedicated sham stimulation coil, designed for controlled clinical trials and research studies that require a convincing active-control condition. It is built on the same pCool platform as the standard PMD70-pCool — delivering identical auditory and tactile sensations to the participant — while the magnetic field is shielded to prevent actual cortical stimulation.

Sham TMS is a critical component of blinded clinical trial methodology, and the PMD70-pCool-SHAM enables fully credible blinding of participants and, in double-blind designs, of operators as well. It is indistinguishable in handling, sound, and physical feel from the active PMD70-pCool coil.

Key Features

• Credible Sham Stimulation: Produces the same click sound and scalp sensation as active TMS stimulation, enabling convincing participant blinding in clinical and research trials.
• Magnetic Field Shielded: Internal shielding blocks the magnetic field from reaching the scalp, preventing any real cortical stimulation while all external cues remain identical to active treatment.
• pCool Platform: Built on the same actively cooled PMD70-pCool body, maintaining identical weight, dimensions, and handling characteristics to the active coil.
• Interchangeable with PMD70-pCool: Direct drop-in replacement for the active coil in any MAG & More stimulator setup, enabling clean within-session counterbalancing in crossover designs.
• Double-Blind Trial Support: Suitable for operator-blinded designs where the coil type is not revealed until after data collection.
• Universal Compatibility: Compatible with all MAG & More stimulator systems.
