The impact of chronic pain varies greatly from person to person, and even changes over time in the same individual.  As a result, chronic pain is a highly individualized experience that defies “one size fits all” treatment approaches.  Nevertheless, you can learn a great deal from other chronic pain sufferers.  What works for others may be a useful addition to your treatment toolbox.

Quell has helped tens of thousands of people with chronic pain.  As for any pain treatment, it won’t work well for everyone.  The best way to determine if Quell can help your chronic pain is to trial it.  However, it is also helpful to see if your personal and pain characteristics match those of typical Quell users.

The following data is taken from the Quell Health Cloud®, which includes uploads from over 90 thousand Quell users who have opted in.  Learn about our privacy policy.

Demographics

56% of Quell users are women.

The average age of Quell users is 56 years, with 30% of users 65 or older.  The youngest Quell user is 11 and the oldest is 105!  The histogram below shows the age distribution of Quell users.

Pain

The typical (i.e., median) pain intensity of Quell users before starting regular use of their devices is 7 on a 0 to 10 scale.  The histogram below shows the pain intensity distribution of Quell users.

71% of Quell users have had chronic pain for at least 4 years and 37% have had chronic pain for more than 10 years.

95% of Quell users have daily pain.  Moreover, 50% have pain throughout each day while 22% report having their worst pain when active.

The impact of chronic pain extends beyond the direct experience of pain intensity to its impact on daily function and quality of life.  This can be measured by asking chronic pain sufferers how much pain “interferes” with various aspects of their life such as sleep, activity and mood.  The typical (i.e., median) pain interference with sleep of Quell users is 6 on a 0 to 10 scale prior to regular use of Quell.  The typical pain interference with activity and mood are both a 7 on a 0 to 10 scale.

Quell is placed on the upper calf and is intended to provide pain relief in that leg, foot and knee.  However, chronic pain usually affects multiple body sites.  The typical Quell user has pain in 3 sites in addition to the lower extremity.  The most common is the lower back (81%).  Quell helps addresses the lower extremity portion of your chronic pain.  It may help you become more active, sleep better and improve your mood, all of which can improve your overall health and chronic pain.  Moreover, Quell could free you up to look into specific pharmacological and non-pharmacological approaches for other pain locations such as topical analgesics, physical therapy, yoga and cognitive behavioral therapy.

Quell users have an average of 3.7 health conditions that may be contributing to their chronic pain.

Sleep

If you wear your Quell device overnight, it will monitor your movements to determine various sleep metrics such as the amount of sleep you get. Learn about Quell sleep tracking

Quell users slept an average of 6 hrs and 46 min (406 min) a night prior to starting regular use of their device.  However, 28% of these users were getting less than 6 hrs (360 min) of sleep which is considered inadequate and could exacerbate chronic pain.  The histogram below shows the distribution of sleep duration among Quell users prior to starting regular use of their devices.

Periodic Leg Movements (PLMs) are repetitive movements of your legs. Quell determines your PLM index, which is the average number of PLMs per hour of sleep.  A PLM index of 5-14 is borderline and 15 or more is considered high.  High PLMs may indicate that you have restless leg syndrome (RLS).  48% of Quell users have a PLM index ≥ 5 and 16% have a PLM index ≥ 15.  You should discuss your PLM index with your physician.

Weather

58% of Quell users report their chronic pain is sensitive to changes in weather.  The most common triggering conditions are rain (46%) and cold (45%).
