OT Mod 5 Flashcards
Changes in tone and structure of the tissues
surrounding a joint may result in??
Varying degrees of rigidity or fixation of the joint at some point within the normal sphere of movement
What is the definition of a Subluxation?
When articular facets are carried by a traumatic force past their limit of normal excursion but short of dislocation.
What are the Important conditions to be
discussed when talking about Subluxation?
1) Rigidity or fixation of spinal joints within their normal range of movement.
2) Bony subluxations in the field outside of the normal range of motion.
Is Joint fixation a loss of all motion?
It should be kept in mind that the absolute loss of all motion is not always meant by “joint fixation.”
What is Joint fixation?
Joint fixation is a loss of motion and function of a segment, but not necessarily total loss of motion between facets.
What would be considered a total loss of motion?
Ankyloses (fusion)
In those conditions where the bones of a spinal joint have become rigid or fixed somewhere within their normal range of movement, the surrounding
supporting tissues may
Lesioned and the bones may not be subluxated.
“The degree of rigidity manifest in a spinal
lesion (and the extent of displacement, if
the joint is subluxated) is indicative of?
“The degree of rigidity manifest in a spinal
lesion (and the extent of displacement, if
the joint is subluxated) is indicative of
the extent and seriousness of soft tissue
involvement.”
When the articulating facets have, by _____, been forced beyond their normal range of movement and the joint has become ___ in that position, then we have a “_______?
When the articulating facets have, by traumatism, been forced beyond their normal range of movement and the joint has become fixed in that position, then we have a “subluxated joint.”
The principle part of spinal treatment is directed to the ______ but the subluxation, the true bony lesion, is often an _________
The principle part of spinal treatment is directed to the restoration of motion in joints; but the subluxation, the true bony lesion, is often an essential factor in consideration.
Restoration of _____joints to
alignment often _____________ and also to
release of tension in spinal tissues.
Restoration of concomitant joints to
alignment often leads to almost
immediate return to normal of tissues
surrounding that joint and also to
release of tension in spinal tissues.
Anterior lesions have ?
Anterior lesions have bilateral joint surfaces held in full overlapping (extension). Palpation elicits thickening and edema over the lesioned joints on either side
Posterior lesions have ?
Posterior Lesions have bilateral facets open as far as possible. Palpation elicits thickening and edema over the lesioned joints on either
side.
Flexion lesion?…
The articulation of the lesion side will flex less than that of the normal side
When the patient bends backward, the
articulation on the lesion side will ??
When the patient bends backward, the
articulation on the lesion side will be held opened up in flexion
A rotation-side-bending lesion with
the tip of the ?
SP moving and pointing towards the
lesioned side
An extension lesion with the tip of the spinous ? (Opposite of?)
Moving and pointing away from the lesioned side. ( a rotation-side-bending lesion)
Eliminating all considerations of pressure
effects and other??
Factors, rigidity of spinal joints impairs the circulation and drainage of theses joints and the spinal cord
A common finding in spinal lesions is ??
A relative lowering of alkalinity in surrounding tissues.
With the fluid of edema (and the PH Alterations? Being???), This would tend to increase?
(Alkalinity)
Conductivity of these tissues, lessen the efficiency of the insulation, and allow a leakage and short circuiting of nerve impulses into the tissues surrounding nerve fibres,
Regardless of type of technique/approach used when the spine is manipulated?
Many reflexes are elicited by touch and by motion.
In the chronic lesion, there is in
addition to the abnormal?
Tension in muscle fibres, fibrous infiltration in muscles and ligaments as a result of congestion and inflammation
A lesion with traumatized and acutely inflamed muscle and ligament may require ?
Less vigorous manipulation, not specific joint movement.
In Forward Bending (?) and Backward Bending (?) the overlaping of the spinal joints?
Forward bending (flexion): the overlapping of the spinal Joints is decreased.
Backward bending (extension): the over lapping of the spinal joints is increased.
