Topic: Flexion


  
  Flexion - Wikipedia, the free encyclopedia
In anatomy, Flexion is movement whereby bones or other objects are brought closer together.
For example, flexion of the arm involves the forearm being brought closer to the arm.
Flexion thereby decreses the angle between the bones of the limb at a joint

 U of MI/Muscles in Action
The actions of the ankle are plantar flexion and dorsiflexion; those of the foot are version and inversion.
The analogous action to wrist flexion is one that would tip the sole of the foot downward, increasing the angle between foot and leg.
The action similar to extension at the wrist would be a tipping of the upper surface (dorsum) of the foot toward the anterior surface of the leg.

For maximum flexion angle data in all four orthoses, the average percent difference between the Optotrak data and the C0 data calculated from the VF digitized measurements was 8.8 percent.
The combined (flexion and extension) average percent difference between the optoelectronic data and VF data was 3.8 percent.
Intercentroidal translational motion restriction in flexion and extension was defined as the difference between the translation of one vertebral centroid from an adjacent vertebral centroid relative to C7.

 Q7. Flexion & Bend
Can you please explain the difference between Flexion and Bend and what on earth does ‘Flexed Straight’ mean as in: “a horse should at all times should show a degree of flexion to either the left or right depending on which rein we are riding.
Longitudinal flexion is therefore when the poll area softens such that the nose in a straight line comes closer to the vertical line.
Lateral flexion is where the horse looks slightly to the left or right in the poll area with the neck and the rest of the body straight.

In a forelimb flexion test, various joints and soft tissue structures of the lower limb are stretched and/or compressed for a brief period of time by bending the limb.
While forelimb flexion tests are quite commonly performed, veterinarians have not agred on the optimum duration of the test, which can vary from 30 seconds to three minutes.
A positive response to forelimb flexion tests, meaning lameness was evident after the limb was released, is one reason horses may be deemed unsuitable for purchase during the prepurchase exam.

 Williams' flexion exercises vs. McKenzie's extension...
Unlike Williams, however, McKenzie theorizes that flexion, not extension, is the culprit.
In contrast to Williams, McKenzie argues that it is an accumulation of flexion forces, not extension, that increases the pressures on the posterior elements of the disc, and that's what causes the problem.
The authors concluded that controlling lumbar flexion in the early morning is a form of self-care with potential for reducing pain and costs associated with chronic, nonspecific low back pain.

 Lateral Flexion is The Key to Vertical Flexion with horses
To start vertical flexion, I begin at the standstill and when he understands that he has to soften to my hands I'll work at the walk then trot and canter.
Vertical flexion (collection) at the walk is basically the same as the standstill.
Don't forget to do some lateral flexion in between your poll softening exercise, just as a friendly reminder to your horse that you are the one that "calls the shots" so to speak.

 DEEP FLEXION TOTAL KNEE ARTHROPLASTY
The goal of deep flexion TKR surgery is to obtain it while still maintaining a balanced, centered, stable knee.
Varus / valgus bone resection errors can also affect ultimate ROM of the knee by unbalancing the collateral ligaments.  Prevention of this error is best preformed by use of cutting blocks based off an intramedullary rod.  Careful central positioning of the IM rod in the distal femur and proximal tibia is important.
            Note that there are some instances in which the prevention of early liftoff prior to obtaining deep flexion is difficult to achieve.  The obese patient, the multiply operated and scarred knee, and knees with severe preoperative contractures are challenging.

 withdraw   (Site not responding. Last check: 2007-11-06)
Around a conference table, colleagues may reveal unvoiced negative feelings in postures influenced by flexion withdrawal, e.g., pulling the hands and arms backward, away from disliked speakers.
In mammals, the most primitive protective response is a flexion withdrawal, which "takes the head and neck away from the stimulus" (Salzen 1979:130).
The crouch posture is "a protective pattern characteristic of the early embryonic flexion response" (Salzen 1979:136).

 Problems Addressed-Flexion
We do not recommend SIRIS™ Splints for severe flexion contractures (greater than 25 degrees).
During use, the wearer can adjust these splints for comfort by squeezing the rings together to allow for more flexion or spreading them apart for more extension.
To put the splint on over a flexion deformity, squeeze the rings together, put the splint on sideways and rotate it up over the joint.

Increasing risks for neck pain due to neck flexion were found with decreasing endurance times (table 4).
The purpose of this study was to identify the longitudinal relation between physical load related to work and neck pain.
A trend for a positive relation between neck flexion and neck pain was found, although not significant, suggesting an increased

 Flexion/Extension Thread
For several years now, notators at the DNB have been trying to find a symbol for flexion and another for bending/folding that is unspecified in terms of the amount.
The sign for the basic movement of flexion, includes the sign for "any", thus giving complete freedom as to which form of flexion may be used (Your Move p.
While this may have been used/tried in the past, AHG suggests that any further use be discouraged.

In Labanotation and Motif Notation “flexion” and “extension” are overall basic family names.
Ann Guest feels the terms “flexion” and “extension” are good umbrella terms, because they seem to balance each other.
For example, it seems less loaded with specific meaning than “flexion.” In teaching situations students sometimes find the word ‘bending” easier to understand.

 MedlinePlus Medical Encyclopedia: Meniscus tears
The meniscus is a C-shaped fibrous piece of cartilage which is found in certain joints and forms a buffer between the bones to protect the joint.
The meniscus also serves as a shock-absorption system, assists in lubricating the joint, and limits the joint flexion and extension.
Meniscal tears are most commonly caused by twisting or hyperflexion of the joint.
