Motion Dynamics Flashcards
Define somatic dysfunction
The impaired or altered function of related components of the somatic system
Four criteria to diagnose somatic dysfunction
TART
Tissue texture changes
Asymmetry
Restriction of motion
Tenderness
Define active ROM
Patient is actively moving
Define passive ROM
Physician is moving the patient
Physiological barrier
Limit of active motion
Anatomic barrier
Limit imposed by anatomical structure
Restrictive barrier
Functional limit that abnormally diminishes the normal physiological range
Elastic range
Range between the physiological and anatomic barrier
This is the end of passive motion
Three types of joints
- Fibrous - skill articulations
- Cartilaginous - discs between vertebrae
- Synovial - 6 types in extremities
Most joints have what in regards to motion
Primary motion in one plane with smaller motions in the other two
Motion has what three things
Direction
Range
Quality
Define direction of motion
Flexion, extension, side-bending, rotation
Define range of motion
Actual measurements are in degrees
Define smooth quality of motion
Define ratcheting quality of motion
Define restricted quality of motion
Define exhibiting quality of motion
Smooth - normal
Ratcheting - parkinsons
Restricted - contracture or somatic dysfunction
Exhibiting - resistance to the motion induced (cerebral palsy)
Define elastic end feel of ROM
Like a rubber band
Define abrupt end feel of ROM
Osteoarthritis or hinge joint
Define hard end feel ROM
Somatic dysfunction
Define empty end feel ROM
Stops due to guarding
Define crisp end feel ROM
Involuntary muscle guarding as a pinched nerve
Static flexibility
Maximal ROM a joint can achieve with an external applied force
Dynamic flexibility
ROM an athlete can produce and speed at which he can produce it
Coupled motion
Consistent association of a motion along or about one axis with another motion about or along a second axis
This is seen in the spine
Functional unit of the spine
Two vertebrae, their associated disc, neurovascular and other soft tissue
Which part of the spine displays the greatest motion
Cervical spine
Common sign of osteogenesis imperfecta
Blue sclera
Ehler-danlos syndrome
Collagen dysfunction
Joint hypermobility
Stretchy skin
Alport syndrome
Deafness
Kidney dysfunction.
Menkes disease
Copper deficiency
Kinky hair, growth failure
Two major criteria for Ehler-Danos Syndrome
- Beighton scale >4
2. Arthralgia for longer that 3 months in 4 or more joints
Minor criteria for Ehler-Danos syndrome
Beighton score >3 Three or more soft tissue lesions Marfoid habitus Drooping eyelids, myopia Mitral valve prolapse Varicose veins, hernia, rectal prolapse
Diagnosis for Ehler Danlos criteria

One major plus two minor
