Femoroacetabular impingement (FAI) is a pathological hip condition found in 17% of the population, and it’s caused by abnormal contact between the ball of hip and the socket. To be more precise, it’s the head-neck junction that impinges against the rim of the acetabulum. There are three types of FAI: cam, pincer, or a combination [..]

When people think of chiropractic care, they usually imagine back pain, neck pain, and headaches, as research STRONGLY supports chiropractic treatment for these complaints. But what about chiropractic care for shoulder pain? In 2010 and again in 2014, the United Kingdom government published landmark studies that reviewed previously published research on various forms of treatment [..]

Knee pain is a common complaint that will affect about 30% of the general population at some point in adulthood. Since running has a reputation for causing knee pain due to “wear and tear”, the question frequently arises as to whether or not running accelerates knee problems. So, what does the current body of research [..]

When people think of hip pain, they generally turn to hip-specific exercises as a self–help strategy. However, recent evidence shows there’s a correlation between poor core stability of the trunk and injury to the lower extremities, which includes the hips. In March 2018, Belgian researchers reviewed data from nine previously published studies with a focus [..]

Adhesive capsulitis (also known as “frozen shoulder”) is the end result of inflammation, scarring, thickening, and shrinkage of the capsule that surrounds the humeral head or “ball” part of the ball and socket joint. Adhesive capsulitis dramatically reduces the range of motion of the affected joint, which can severely impact one’s ability to carry out [..]

About a quarter of adults experience frequent knee pain, which results in limited function, reduced mobility, and impaired quality of life. Osteoarthritis (OA) is the most common cause of knee pain in those over 50 years of age, and it is the #1 reason for total knee replacement (TKR). The rate of TKR in the [..]

The term deep gluteal syndrome (DGS) describes a condition that causes pain in the buttock that may travel down the back of the leg when the sciatic nerve is irritated. There are various structures that can result in sciatic nerve entrapment within the gluteal space which include the following: the piriformis muscle; fibrous bands containing [..]

Each year, Americans make 7.5 million doctor visits related to shoulder/upper arm pain. After neck and back pain, shoulder pain is one of the top reasons patients seek chiropractic care. So, why are shoulder injuries so prevalent? Though there are many possible explanations that address this question, there’s a simple answer: anatomy. There are essentially [..]

Sports that require rapid acceleration and deceleration, cutting left and right, agility, jumping, and bending pose a unique risk for injury to the lower limbs. Hamstring injuries are the most prevalent injury in Australian rules football, afflicting 16% of players, causing an average of 3.4 missed matches per injury, accounting for the most time lost [..]

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 [..]
