The study published shows that even correcting for body mass index and age, osteoarthritis of the knee is twice as common now as it was before the 1950s.
Neural Plasticity – Learning Posture and Movement Patterns
Neural Plasticity explains how the nervous system learns and patterns our postures and movement patterns, as well as our memories and sensitivity to pain.
Precautions for Manual Therapy of the Lumbar Spine and Pelvis
The low back and pelvis contain a number of sensitive structures whose locations are important to know because they contraindicate deep pressure.
Ligaments of the Lumbar Spine and Pelvis
The “action” of a ligament is similar to that of an antagonist muscle. If either is tight/taut, it restricts motion to the opposite side.
Muscles of the Pelvis
Pelvic musculature: 1. cross the LS joint onto the trunk 2. cross the hip joint onto the thigh/leg 3. pelvic floor muscles located wholly within the pelvis
Muscles of the Lumbar Spine of the Trunk
Structural groups of muscles largely determine functional groups—that is, the structural location of a muscle largely determines its mover function.
Motions of the Joints of the Pelvis (sacroiliac joints)
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 …
Motions of the Joints of the Lumbar Spine
Motions of the lumbar spine: The lumbar spine can move axially and nonaxially in all three cardinal planes (sagittal, frontal, and transverse).
Joints of the Lumbar Spine (disc & facet) and Pelvis
In the lumbar spine, three joints are located between each two adjacent vertebrae: one disc joint and two paired (left and right) facet joints.
Bones of the Lumbar Spine and Pelvis
The low back is defined by the lumbar spine, composed of 5 vertebrae, named L1-L5. The pelvis is defined by the bones of the pelvic girdle.
How do we treat plantar fasciitis with manual therapy?
Manual therapy for plantar fasciitis is aimed at reducing inflammation & loosening any tautness/tightness of the plantar fascia & associated musculature.
Student Tip for Improving Memory – Memory is the residue of thought…
Two main points for improving memory: Memory is the residue of thought. A cue is needed to recall something that has been successfully committed to memory.
What is the “True” Function of the Gluteus Medius?
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.
Client Communication – How is the pressure?
The most common question from a therapist to the client is: “How is the pressure?” The usual response is “Fine”, whether it is or not.
Signs, Symptoms, and Assessment of Plantar Fasciitis
The most common symptom of plantar fasciitis is pain, usually worst in the morning, on the plantar side of the foot, located near the calcaneal attachment.
Massage on Stretch or Massage on Slack? Tips for Therapists & Teachers
Tip for Therapists: Massage on stretch for superficial tissues like the trapezius. Massage on slack for deeper tissues like the suboccipitals.
Thinking Fast Makes you Happier! – Tip for Teachers and Students
People become happier when they think fast. It does not matter what was, the simple act of generating thoughts quickly made the participants happier.
Heel spur and its relationship to plantar fasciitis
Plantar fasciitis and heel spur: Once the mechanism of plantar fasciitis is understood, the development of a heel spur is easy to understand. A heel spur is a bone spur that forms on the calcaneal tuberosity along the line of …
FREE DCOMT video – One Handed Towel Traction for the Neck with Shoulder Girdle Stabilization
Neck traction performed with a towel, along with stabilization of the shoulder girdle, thereby increasing the strength of the traction force.
What is Muscle Memory?
Muscle memory describes the concept that musculature contracts in patterns for both posture and motion, and these patterns reside in the nervous system.
What is plantar fasciitis and what are its causes?
Plantar fasciitis is a condition in which the plantar fascia (plantar aponeurosis) of the foot becomes irritated and inflamed.
Psoas Major Function: References
This blog post contains the cited research references for the eleven-part blog post series on Psoas Major Function that is found on Learnmuscles.com.
Psoas Major Function: Summary of Psoas Major Function
Looking at the psoas major from a biomechanical perspective might be the key to understanding this elusive and controversial muscle.
Psoas Major Function: Psoas Major and Fascial Pulls
The psoas major’s has extensive fascial connections. The psoas major is part of the deep front line myofascial meridian (anatomy train).
Psoas Major Function: Psoas Major and the Sacroiliac Joint
The psoas major crosses the hip and spinal joints. However, it is often overlooked that the psoas major also crosses the sacroiliac joint.
Psoas Major Function: Stabilization of the Spine by the Psoas Major
A healthy joint is both mobile and stable. However, some sources are concerned about the psoas major’s compression/stabilization effect upon the spine.
Psoas Major Function: Spinal Joint Actions – Sagittal Plane
The psoas major’s sagittal plane lumbar spine joint action is by far its most controversial function. The term “psoas paradox” describes this controversy.
Psoas Major Function: Spinal Joint Actions – Frontal and Transverse Planes
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.
Psoas Major Function: Hip Joint Actions – Transverse Plane
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.
Psoas Major Function: Hip Joint Actions – Frontal Plane
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.
