It is common to feel buzzing or “pins and needles” sensations when using stimulation devices, especially if you're new to them. Motive delivers an electrical stimulation therapy to activate motor neurons.  Electrical stimulation may cause pins and needles, especially at lower intensity values.  

We encourage you to increase your “Knee” and “Thigh” intensities to turn the pins and needles sensation to muscle flexing. 

If the sensation becomes unbearable, there are a few things you can check:

• First, shaving:  Make sure you did not shave your thigh on the same day applying the therapy.  The skin pores stay open for a day when you shave your skin and may irritate therapy. 
• Second, the life of the Therapy Pad: If the Pad has dried out, it may contribute to a more intense sensation. Make sure your Therapy Pad is sticky and not old.  Additionally, ensure the gel on your Pad is intact. 
• Third, Pad positioning:  Ensure your Therapy Pad is positioned correctly on your thigh, directly over the knee and thigh muscles. If it's not placed accurately, you may experience a shocking sensation. Take a moment to adjust the position according to the following image:
