How do I attach the electrode to the device?

How To Attach
Place the device into the band with the lights facing up. Align the snaps on the electrode to the snap connectors on the back of the device. Insert snaps until they are securely fastened. Remove the liner covering the electrode before placing the device on your leg. Remember to keep this liner as it should be placed back on the electrode to protect the electrode while it is not in use.

Where is Quell worn?

Where is Quell Worn

Quell is worn 1-2 inches below the knee, with the lights facing up so you can see them. It does not matter which leg you wear it on.  The device should be resting on the inside, outside or back of the calf.  We recommend not wearing the device directly on the shinbone (although the electrode may be in contact with the front of the leg). Electrodes must be in direct contact with the skin.

Can I wear Quell anywhere but my upper calf?

Quell is designed to be worn 1-2” below the knee so that it can stimulate the cluster of sensory nerves in the calf. If for whatever reason you cannot wear Quell 1-2” below your knee, Quell can also be worn just above the knee (on the lower thigh) or on the middle of the calf.

Skin Care Tips

Mild skin irritation is a potential side effect of Quell. This page contains helpful tips about how to minimize your risk of skin irritation and maximize your pain relief with Quell.

Give your skin some time to air out by removing the device after 4-5 hours of wear. At this time, you may switch Quell to the other leg, or simply take it off altogether. Quell will pulse every 4-5 hours to remind you to air out your skin.

Switch legs if/when possible.

Wearing Quell in the same spot consistently can increase your risk of skin irritation. Alternating or switching legs can minimize that risk by limiting the exposure level of one patch of skin.

Moisturize dry skin.

Dry skin is more susceptible to irritation. Apply moisturizer to the leg 20-30 minutes before using Quell.

Do not wrap the Quell band too tightly.

Wrapping the Quell band too tightly can cause the electrodes to unsnap and can lead to skin irritation. Only wrap the band tightly enough to keep Quell in place.
