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
