PainRelief.com:  What is the background for this study?  What are the main findings?

Response: Chronic low back pain (CLBP) is the most prevalent chronic pain (CP) condition and the leading global cause of years lived with disability. According to the axiom pain as a biopsychosocial issue, mood and sleep disturbances represent key issues. However, the impact of different analgesic therapies on quality of life (QoL) and functional recovery has been poorly assessed to date. Focusing on combination of chronic pain and sleep, they both perform a mutual reinforcement.

Pain disorganizes the sleep architecture, and disturbed and unrefreshed sleep increases spontaneous pain and lowers pain thresholds. Sleep disorders may augment stress levels, thus making it difficult for patients to perform simple tasks impairing their cognitive ability. Poor sleep may predict the growth and intensification of pain over time, with increased insomnia symptoms being both a predictor and an indicator of worse pain outcomes and physical functioning status over time. Epidemiology of chronic pain unequivocally demonstrates the role of sleep quality in the development of chronic pain.

Notwithstanding this strong two-way relationship between chronic pain and sleep, little knowledge is available about the neurochemical determinants of this interplay and therapeutical strategies to break this vicious circle. Fifty percent of people with chronic low back pain have sleeping disturbances, with an 18-fold increase in insomnia versus healthy people. A recent study investigated the relationship between sleep disturbances and back pain and found that it is two sided with sleep disturbance being associated with risk of back pain whilst back pain can also lead to sleep disturbances. Thus, it can be hypothesized that, by reducing pain and physical dysfunction, sleep quality could be improved, thus enriching the QoL of people with CLBP.

Similarly, improvements in sleep after cognitive behavioral therapy in patients with chronic pain due to osteoarthritis were associated with reduced pain. Earlier evidence suggested that tapentadol prolonged-release treatment ameliorate in parallel QoL and sleep quality in a greater proportion of patients compared to that of patients following oxycodone/naloxone prolonged- release treatment (50% versus 37.7%). Other tapentadol studies conducted in a real-life context documented, along with effective pain control, similar improvements in mental and physical health and suggested beneficial effects in terms of less night awakenings and greater percentages of patients reporting restful sleep.

PainRelief.com:  What is the background for this study?  What are the main findings?

Response: Sleep disturbance and insomnia are common among people with chronic low back pain (cLBP). Previous research showed that 59% of people with cLBP experience poor sleep quality and 53% are diagnosed with insomnia disorder. Medication for both sleep and back pain can have serious side effects, and risk of opioid-related overdose and death increases with use of sleep medications. Given the serious risks of combining pain and sleep medications, we evaluated the use of nonpharmacologic approaches to manage sleep quality in adults with chronic low back pain.

Our randomized controlled trial included 320 adults with chronic low back pain from predominantly low-income racially diverse neighborhoods of Boston. At the beginning of the study, over 90 percent of participants with cLBP reported poor sleep quality. Participants were randomly assigned one of three different therapies for cLBP: physical therapy (PT), weekly yoga, or reading educational materials. Our previous research showed that yoga and PT are similarly effective for lowering pain and improving physical function, and reduced the need for pain medication. In this study, results for sleep improvements were compared over a 12-week intervention period and after 1 year of follow-up.

Self-Reported Prescription Drug Use for Pain Relief and Sleep Linked to Frailty.

Dr. Bergen

PainRelief.com:  What is the background for this study?

Response: The background to the study is examination of the incident frailty risks of two classes of prescription drugs commonly co-prescribed in response to pain and sleep indications.

The dataset consisted of N=7,201 non-frail, age 65+, community-living individuals from the Health and Retirement Study, a nationally representative longitudinal cohort interviewed every two years.

The drug exposure measures are based on responses to the two questions: “Do you regularly take prescription medications for any of the following common health problems:

For pain in your joints or muscles?” and “Do you regularly take prescription medications for any of the following common health problems: To help you sleep?”.

The outcome measure was the Burden Model of frailty using the conventional threshold of >0.2 for frailty.

Osteoarthritis: Poor Sleep Linked to More Pain

PainRelief.com:  What is the background for this study?  What are the main findings?

Response: Older adults with osteoarthritis commonly report symptoms of pain, fatigue and poor sleep quality. Previous research has investigated how this symptoms are cross-sectionally and longitudinally associated with each other. However, no previous studies have investigated how the quality of a night’s sleep impacts on the next day’s course of pain and fatigue in this clinical population.

We found that poor sleep quality was associated with greater pain intensity and fatigue on awakening when compared to a good night’s sleep and that, over the course of the day, the effects were sustained. Although a night of better quality sleep was associated with less pain and fatigue on awakening,  these symptoms worsened more rapidly throughout the day, such that as the day progressed the effect of the previous night’s sleep became less and less important.

PainRelief.com:  What is the background for this study?

Response: Sleep is essential in the regulation of a wide range of homeostatic functions.  Dysregulation of sleep process may be triggers for migraine attacks and increase the risk of migraine disease chronification.  Migraine is comorbid with a range of medical, neurologic, and psychiatric comorbidities that may exacerbate the disease, complicate treatment, and reduce health-related quality of life.  These comorbidities include sleep disorders such as sleep apnea, insomnia, circadian rhythm (i.e., sleep-wake) disorders, and sleep movement disorders.

The Chronic Migraine Epidemiology and Outcomes (CaMEO) Study is a longitudinal study that used a series of web-based surveys over 15 months to assess migraine symptoms, burden and patterns of healthcare utilization among people in the US population.  Validated questionnaires were used to assess many comorbidities.  Migraine can be classified based on the number of headache days per month into episodic migraine (<15 headache days/month) and chronic migraine (≥15 headache days/month).

In this cross-sectional analysis of data from the Chronic Migraine Epidemiology and Outcomes (CaMEO) Study, we assessed sleep apnea and poor sleep quality in a US population based sample of 12,810 people with migraine.  Respondents were stratified by episodic (11,699) and chronic (1,111) migraine and by body mass index (BMI).
