Here is my paper. I had to write a summary of the article that I read. At the bottom is the reference, which includes all of the information for the article if you are interested in finding it for yourself.
Summary of A Pilot Study of Audio-Visual Stimulation as a Self-Care Treatment for Insomnia in Adults with Insomnia in Chronic Pain
Chronic pain and sleep disturbances are comorbid conditions, meaning they are often diagnosed in the same patient. It is estimated that one in three Americans suffers from chronic pain, and as many as 88% of those suffering from chronic pain also suffer from some sort of regular sleep disturbance (Tang, Vitiello, Perlis, Mao, & Riegel, 2014); that equates to about 78 million American adults suffering from chronic pain, with about 68 million also suffering from sleep difficulties (Howden & Meyer, 2011). These statistics show a shockingly high level of comorbidity, and a need for a solution. It has also been suggested that the relationship between pain and sleep may be bidirectional, meaning that increased sleep disturbances increases pain levels and increased pain levels increases sleep disturbances. Sleep disturbances have also been linked to other physical and psychiatric problems, which have also been shown to cause chronic pain problems, suggesting that treatment for chronic pain should focus on sleep disturbances.
This neck/shoulder/back stuff, however, seems to be pushing it. I think I finally found a limit. A hard and fast limit.
