Smoking tobacco causes more than 480,000 deaths annually, which makes it the leading cause of preventable death in the United States (US)—that is nearly one in every five deaths in the country! Smoking causes more deaths than HIV, illegal drug use, alcohol abuse, car accidents, and firearm-related deaths COMBINED. More than ten times as many [..]

Is it possible to identify which low back pain patients might experience the most benefit from spinal manipulation combined with exercise? In a 2011 study, researchers identified which patients might respond best to this combination of care and which patients might need a more aggressive approach. Directional preference (DP) describes a situation in which it [..]

Experts estimate that up to 70% of people will experience an episode of neck pain in their lifetime. Though there are many potential forms of treatment available, little has been published comparing the various treatment options available to the neck pain patient. A 2012 study that involved 272 neck pain patients compared three treatment options: [..]

Numbness in the hand is a common problem that we’ve all had at one time or another, and unless it becomes frequent, we usually don’t worry too much about it. When it starts to wake us up at night, that SHOULD get our attention! Since carpal tunnel syndrome (CTS) is one of the most common [..]

The hip and knee are anatomically very close to one another. Functionally, there are several muscles that attach above the hip and below the knee joint. Hence, depending on the position and/or activity, the same muscle can move the hip and/or the knee. This close relationship crosses over in dysfunction as well, as patients with [..]

Whiplash-associated disorders (WAD) is defined as “an acceleration-deceleration mechanism of energy transfer to the neck.” WAD may result from rear-end or side-impact motor vehicle collisions (MVCs), diving and other sports-related injuries, as well as from falls, assaults, and more. Because many bones and soft tissues may be involved in WAD, there are a variety of [..]

As discussed previously, probiotics can benefit patients with gut complications such as enteritis, constipation, and irritable bowel syndrome (IBS). Probiotics may also help decrease allergic inflammation, treat nonalcoholic fatty liver disease (NAFLD), and fight immune deficiency diseases. Ingesting probiotics can improve calcium absorption and bone calcium accretion to treat osteoporosis in postmenopausal women. They may [..]

Data from the Chiropractic Profession Continue to Become Better Defined and UnderstoodBackgroundPain is a huge problem in America, and all Americans know that opiate drugs are not the solution to our pain problem.In her 2014 book, A Nation in Pain, Judy Foreman claims, “Out of 238 million American adults, 100 million live in chronic pain.” (1) [..]

Dysmenorrhea, also known as painful periods, is a common gynecological condition that affects up to 70% of menstruating women. About 15% of individuals with the condition report that it significantly interferes with their activities of daily living (ADLs) and in some cases, results in absence from school and/or work. Studies have found that dysmenorrhea is [..]

According to the Vestibular Disorders Association, there is a classification of dizziness called “cervicogenic dizziness”, or dizziness resulting from neck pain. Published reports have linked the influence of head position on equilibrium as far back as the mid-1800s, but it wasn’t until 1955 when researchers coined the term “cervical vertigo” to describe a clinical condition [..]

Let’s say you’ve applied for a job that requires frequent gripping and handling of products and you heard that carpal tunnel syndrome (CTS) is a problem at this particular manufacturing plant. You really need the job, but you are leery of the possibilities of developing CTS. Is there anything you can do to PREVENT it? [..]

The shoulder is not just one joint but rather four: the sternoclavicular (collar bone/breast bone), acromioclavicular (the “roof” of the ball & socket joint), glenohumeral (the ball & socket joint), and scapulothoracic joints (shoulder blade/rib cage joint). There are also many structures in the vicinity that can mimic shoulder pain—namely, the cervical spine (neck), the [..]
