Arthritis: The spondyloarthropathies are inflammatory types of arthritis that can affect the lower back and sacroiliac joints. Examples of spondyloarthropathies include reactive arthritis (Reiter's disease), ankylosing spondylitis, psoriatic arthritis, and the arthritis of inflammatory bowel disease. Each of these diseases can lead to low back pain and stiffness, which is typically worse in the morning. These conditions usually begin in the second and third decades of life. They are treated with medications directed toward decreasing the inflammation. Newer biologic medications have been greatly successful in both quieting the disease and stopping its progression.
Prolonged sitting and activities like running or cycling can lead to tight hip flexor muscles and a variety of skeletal imbalances. Think: if you only cycle for exercise, certain muscles in your legs will get stronger (in a lot of cases you overwork these muscles) yet your core and outer hip muscles might get weaker from lack of engagement. So what? Well, these muscle imbalances often lead to skeletal imbalances and injuries down the line. If you have particularly tight hip flexors, your body will start to create an anterior pull on the pelvis (anterior pelvic tilt). You can identify an anterior pelvic tilt if your belly protrudes slightly in the front while your butt sticks out in the back (what some people refer to as “duck butt”).
To avoid hip flexor pain, you should pay more attention to these muscles, Dr. Siegrist explains. When you are seated, your knees are bent and your hip muscles are flexed and often tighten up or become shortened. “Because we spend so much of our time in a seated position with the hip flexed, the hip flexor has the potential to shorten up. Then, when you are in a hurry because you are running to catch a bus or a plane, or you trip and fall, the muscle could become stretched. Here’s this stiff, brittle muscle that all of a sudden gets extended, and you could set yourself up for strain or some hip flexor pain.” Click Here to Learn Unlock Hip Flexors
