The cauda equina (Latin for “horse’s tail”) is made up of many nerves that travel down and exit out the sides of the lumbar spine and sacrum (tail bone) and transfer information (motor and sensory) to and from our legs and brain. If the cauda equina becomes compressed, the resulting cauda equina syndrome (CES) is [..]

Experts estimate that approximately 10% of the adult population in the United States experienced an episode of tinnitus—the perception of sound or noise without any external auditory stimulus being present—within the last year. Tinnitus can be caused by wax buildup in the ear, medication side effect, noise-induced hearing lost, ear and sinus infections, cardiovascular disease, [..]

Because the early symptoms of carpal tunnel syndrome (CTS) can be mild and tolerable, many patients put off seeing a doctor until the pain, numbness, tingling, and weakness in their wrist and hand is no longer bearable.  The current research supports chiropractic care as an excellent non-surgical option for new-onset CTS, but what about patients [..]

A Baker’s cyst is a swelling located in the back of the knee that can be either asymptomatic or bothersome, especially when bending the knee. Researchers estimate that up to 94% of popliteal (back of the knee) cysts are associated with an intra-articular disorder, most commonly meniscus (“cartilage”) tears, as well as osteoarthritis, inflammatory arthritis [..]

When it comes to whiplash associated disorders (WAD), the process of making an accurate diagnosis and treatment recommendation can vary from healthcare provider to healthcare provider depending on their educational background, ongoing training, and clinical experience.

Coffee is one of the most consumed beverages around the globe, and many individuals can’t seem to start their day without a cup or two.

The roots of the sciatic nerve exit the spine through several levels in the lower back, join in the buttock region, and travel down into the lower extremities. When pressure is applied to the sciatic nerve in the lower back area, it can generate pain and other sensations down the nerve into one of the [..]

Doctors of chiropractic often approach neck pain with manual therapy as the primary form of treatment. However, there are several types of manual therapy, including high velocity, low amplitude (HVLA) thrust manipulation; mobilization; and/or soft tissue techniques. Is one type of manual therapy superior when it comes to managing neck pain? What does the research [..]

In addition to manual therapies and specific exercises to relieve pressure along the course of the median nerve as it passes through the wrist and elsewhere, doctors of chiropractic may utilize other high- and low-tech tools to manage the condition: Electric stimulation (e-stim) directs an electric current via electrodes placed on the skin over or [..]
