How Can SENSUS Help Improve Your Sleep?

Friday, July 18th, 2014

Chronic pain and poor sleep are closely associated. As many as 50-70% of people with chronic pain also suffer from sleep problems. For example, about 50% of people with painful diabetic neuropathy, a common form of chronic pain in people with diabetes, have sleep disturbances or insomnia.
Chronic pain prevents people from falling asleep and maintaining restful sleep. At the same time, a chronic lack of sleep amplifies pain. The inter-relationship between chronic pain and poor sleep underscores the importance of treating both conditions in order to improve pain, sleep, health and quality of life.

Here’s how SENSUS can help. SENSUS may be used at bedtime to help you fall asleep, and throughout the night to help maintain high quality sleep. SENSUS provides pain relief by stimulating the nerves that carry normal non-painful sensations to your brain. Stimulation of these nerves changes the levels of certain natural chemicals in your nervous system that decreases your pain. SENSUS is the only transcutaneous electrical nerve stimulator approved by the FDA for use during sleep; so you can be confident that it is both safe and effective for you to use overnight. Read More

The Cycle of Chronic Pain and Disrupted Sleep

Wednesday, July 16th, 2014

Many people with chronic pain also suffer from disrupted sleep.  A recent article published in Neurology Reviews, Breaking the Cycle of Chronic Pain and Disturbed Sleep, looked at this relationship and the role that some pain medications may have in further disrupting sleep. Read More

The Association of Chronic Pain and Obstructive Sleep Apnea

Thursday, June 19th, 2014

Chronic pain and disrupted sleep are commonly associated and they share a circular relationship - pain disturbs sleep, and poor sleep worsens the pain response.  It is estimated that 28 million Americans have sleep complaints due to chronic pain syndromes. A recent article published by Medscape The Association of Obstructive Sleep Apnea and Chronic Pain looks at this bidirectional relationship between chronic pain and obstructive sleep apnea.   Read More

Links Between Obstructive Sleep Apnea and Diabetic Peripheral Neuropathy

Thursday, May 8th, 2014

Obstructive sleep apnea (OSA) is a common disorder that is prevalent in people with Type 2 diabetes.  It is characterized by upper airway instability during sleep, resulting in markedly reduced or absent airflow.  People with untreated sleep apnea frequently stop breathing during their sleep, which results in fragmented, low quality sleep. Diabetic peripheral neuropathy (DPN) affects over 50% of people with diabetes. If left untreated, diabetic neuropathies trigger foot ulcers that may require amputation and cause disabling pain in the form of painful diabetic neuropathy. An interesting study by Tahrani and colleagues published in the American Journal of Respiratory and Critical Care Medicine ( in 2012, evaluated the link between OSA and DPN from both clinical and pathophysiological perspectives.  The prevalence of DPN was 60% in subjects with OSA and only 27% in those without OSA.  The study identified increased nitrosative/oxidative stress and impaired microvascular regulation in OSA subjects.  These are pathophysiological processes that may damage peripheral nerves and thereby cause DPN.  The authors concluded by hypothesizing that OSA treatment, such as CPAP, may have therapeutic benefits in patients with DPN.
