A 2009 study that monitored over 8,800 elderly French adults found that an individual’s blood pressure can fluctuate with the seasons. In particular, the researchers observed that as temperatures fell, both systolic and diastolic blood pressure could rise to unhealthy levels, but they were unable to determine why. However, a study published just five years [..]

The Morning Shower The typical morning shower is neither 100% cold water nor 100% hot water, but rather a balance of the two. The perfect shower water temperature is a balance of hot and cold water. While enjoying the perfect shower, if suddenly the hot water is turned drastically higher, the brain perceives: Ouch! The [..]

While under chiropractic treatment, it’s not uncommon for a patient to report improvement for an issue that seems unrelated to their chief complaint. For example, a patient with a temporomandibular disorder may experience an improvement in their jaw symptoms following treatment to the neck or upper back. Or treatment to improve hip function may also [..]

Neck pain is the second most common reason patients seek chiropractic care, and it’s particularly a problem with office workers. One study estimated that neck pain affects 42-69% of those who work in office environments. Many such individuals will experience recurring episodes of neck pain, and at least one in six may develop chronic, ongoing [..]

Of all the potential contributing factors for carpal tunnel syndrome—diabetes, thyroid dysfunction, inflammatory arthritis, pregnancy, birth control usage, and obesity—perhaps the most well-known is participating in jobs and activities that require fast, repetitive hand movements that can place increased pressure on the median nerve as it passes through the wrist. What can someone do if [..]

Osteoarthritis (OA) is the leading cause of knee pain and disability in the elderly population. While treatment to address knee OA will often focus on the knee itself, a patient may also need to change their footwear. Why is that? During normal walking, joint loading is NOT evenly distributed, and the distribution most often greatest [..]

A study published in 2019 found that nearly half of whiplash associated disorders (WAD) sufferers are still symptomatic one year after their injury. Why is that, and what can one do to reduce their risk for chronic WAD symptoms? The most common source of pain from WAD injuries arises from joint capsules and ligaments, which [..]

It’s common for the elderly to have multiple chronic conditions, all of which can impact their ability to live a vibrant, independent lifestyle. While it may not be possible to avoid adverse health conditions in our later years, it appears there are steps we can take now to give ourselves the best possible chance to [..]

Decision Making Standards of Care Considering Trauma, Disease, Degenerative Changes, Anomalies, and Biomechanics Weighing Risks Associated with Ionizing Radiation History has recorded chiropractic-like providers for millennia. In his 1992 book (1), Scott Haldeman, DC, PhD, MD (neurologist, University of California, Irvine), includes a chapter titled “Spinal Manipulation Before Chiropractic.” Written by anthropologist Robert Anderson, MD, [..]

Scoliosis is a condition that affects about 3% of teenagers, though the cause is typically unknown. In most instances, the degree of spinal curvature is mild (10-15º curve), but in some cases, the curve may continue to increase as the child grows. Visible signs of adolescent idiopathic scoliosis include the following: uneven shoulders, one shoulder [..]
