The principle of “creep” states that a sustained force placed upon a tissue will deform that tissue to the force. In this study of foam rolling the ITB…
Femoroacetabular impingement syndrome is a movement-related condition, usually caused by abnormal bone formation of the femoral head and/or acetabulum.
The authors suggested that experienced dancers demonstrate safer landing strategies compared to recreational athletes. Dance training experience may provide protection against high-risk movement patterns. And thus, dance training may be modeled to prevent ACL injuries.
So, if hip abductor group on one side is tighter at baseline tone than the hip adductor group on that side, the pelvis will be pulled into depression on that side, resulting in a lumbar scoliosis that is convex on that side. Similarly, tight opposite-side hip adductor musculature can cause the same scoliotic curve.
Tight hip flexor musculature causes excessive anterior tilt of the pelvis… hyperlordosis of the lumbar spine… hyperkyphosis of the thoracic spine… hypolordosis of the lower neck with hyperextension of the head at the atlanto-occipital joint… forward head carriage… tight posterior neck muscles… headache.
Stretching the rectus femoris of the quadriceps femoris group. The rectus femoris is the only quadricep muscle that crosses the hip joint. It crosses it anteriorly with a vertical direction to its fibers, so it flexes the thigh at the hip joint and it anteriorly tilts the pelvis at the hip joint.
Even when the original reason for the sacroiliac stabilization is valid, often the human body overdoes it and tightens the musculature excessively and/or keeps it tight long after it needs to be, so the musculature becomes stuck in a chronic pattern of hypertonicity.
The study demonstrated that four sessions of MFR of the lower limb can induce an improvement in the isolated external hip joint rotation. The authors hypothesized that the improvement in the hip joint’s ROM was due to reduced myofascial stiffness after the MFR treatments.
The authors concluded that decreased hip ROM in professional soccer players is associated with more hip pain and groin pain and is associated with previous injuries, independent of the presence of a cam deformity.
Patients with lateral hip pain on Single Leg Stance and who are not palpably tender over the greater trochanter are unlikely to have gluteal tendinopathy.
Results showed that there were significant shoulder joint ROM increases following both lower body static stretching and lower body dynamic stretching.
Stretching all hip flexors, including the rectus femoris of the quadriceps group, is extremely important for clients with lower crossed syndrome.
Motions of the Joints of the Pelvis This blog post article is an overview of the motions of the joints of the pelvis: the paired left and right sacroiliac joints and the symphysis pubis joint. For more complete coverage of …
The major function of the gluteus medius is its “reverse” closed-chain action of pelvic depression at the hip joint to stabilize the pelvis when walking.
The frontal plane spinal action of the psoas major is fairly clear; it crosses the spinal joints laterally, so it lateral flexes the spine to that side.
The function of the psoas major has been claimed to be both medial rotation and lateral rotation. However, most sources agree that it is a lateral rotator.
If the psoas major frontal plane open-chain action is abduction of the thigh at the hip joint, the closed-chain action is depression of the pelvis.
Note: This is the third blog post article in a series of 11 articles on Psoas Major Function. See below for the other articles in this series on psoas major function. The hip joint is a triaxial joint that allows …
The psoas major is first and foremost, a muscle of the hip joint; however it is more complicated because it also crosses the spinal joints.
The Psoas Major may hold the distinction of being the most important as well as the most misunderstood muscle in the human body.
The quadratus femoris is a deep lateral rotator of the hip joint that is overlooked because of our excessive focus on its neighbor, the piriformis.
5 Pilates Mat Abdominal Series exercises: Single Leg Stretch, Double Leg Stretch, Single Straight Leg Stretch, Double Straight Leg Stretch, & Criss-Cross.
This 3D Animation demonstrates how the piriformis changes its joint action from being a lateral rotator of hip joint to being a medial rotator.
