Lecture 4: motion dynamics Flashcards
Somatic Dysfunction
is defined as the impaired or altered function of related components of the somatic (bodywork) system including: the skeletal, arthrodial, and myofascial structures, and their related vascular, lymphatic, and neural elements.
TART
- Tissue texture changes
- Asymmetry
- Restriction of motion
- Tenderness
Active ROM
patient does the moving
–Patient is Active
Passive ROM
doctor does the moving
–Patient is Passive
what is the limit of active range of motion?
physiologic barrier
what is the limit of passive range of motion?
anatomic barrier
elastic range
between physiologic barrier and anatomic barrier (increased by stretching)
-end of passive motion
sagittal plane
- right left axis
- flexion and extension
frontal (coronal) plane
- anterior posterior axis
- sidebending
horizontal (transverse) plane
- superior inferior axis
- rotation
fibrous joint
-skull articulations
cartilaginous joints
discs between vertebrae
synovial joints (6 types)
- extremities
1) pivot
2) hinge
3) saddle
4) ball and socket
5) condyloid
6) plane
what are the 3 aspects of motion?
- direction
- range
- quality
types of quality of motion
- Smooth – normal
- Ratcheting – ex. Parkinson’s disease
- Restricted – contracture or somatic dysfunction
- Exhibiting resistance to the motion induced – cerebral palsy
elastic end feel
like a rubber band
abrupt end feel
osteoarthritis or hinge joint
hard end feel
somatic dysfunction
empty end feel
stops due to guarding (patient
doesn’t allow the motion due to pain)
crisp end feel
involuntary muscle guarding as
in pinched nerve
static flexibility
maximal ROM a joint
can achieve with an
externally applied force (like passive ROM
dynamic flexibility
ROM an athlete
can produce and speed at
which he/she can produce it
stiffness
reduced
ROM of a joint or
group of joints
functional unit of spine
two vertebrae, their associated
disc, neurovascular, and other soft tissues
which part of spine displays greatest range of motion?
Cervical Spine
coupled motion
consistent association of a motion along or about one axis, with another motion about or along a second axis. The principle motion cannot be produced without the associated motion occurring as well.
what is an example of coupled motion?
the spine
what does linkage do?
increases ROM
what does a specific joint assessment require?
joint isolation for accurate measurement and evaluation
what is used to diagnose Ehlers-Danlos syndrome?
beighton score +brighton criteria
menkes disease
Copper deficiency
–Kinky hair, growth
failure, deterioration of
nervous system
alport syndrome
- Deafness
* Kidney dysfunction
Ehler-Danlos
syndrome
- Collagen dysfunction
- Joint hypermobility
- Stretchy skin
Osteogenesis
Imperfecta
Blue Sclera
Multiple Fractures
Scurvy
Vitamin C deficiency
Requirement for Ehrler Danlos diagnosis
•Any one of the following: –Two major criteria –One major plus two minor criteria –Four minor criteria –Two minor criteria and unequivocally affected first degree relative in family history
what is the major criteria for Ehrler Danlos diagnosis?
- Beighton score of >4
* Arthralgia for longer than 3 months in 4 or more joints
