Motion Dynamics Flashcards
Physiologic barrier?
Limit of active motion
Elastic range?
Range between the physiologic and anatomic barrier (end of passive motion, doctor is doing the motion)
Anatomic barrier?
Limit of ROM imposed by anatomic structure
Restrictive barrier?
Functional limit that abnormally diminishes the normal physiologic range.
Motion plane?
Flat surface on which a straight line joining any two points on it would wholly lie
Motion axis?
Straight line around which an object rotates
Coronal/frontal/lateral plane
Bisects the body into front and back halves
Sagittal/antero-posterior plane
Bisects the body into right and left halves
Horizontal/transverse plane
Divides the body into superior and inferior
Sagital horizontal axis?
Sagittal plane: Flexion and extension on the axis
Frontal horizontal axis?
Frontal coronal plane, Side bending, Horizontal/transverse: abduction, adduction
Vertical axis?
Transverse plane, rotation
Type of joint found between C1 and C2
Pivot joint
Type of joint found in the hip?
Ball and socket synovial joint
Type of joint found in radius and carpal bones
condyloid synovial joint
type of joint found between tarsal bones
Plane synovial joint
Type of joint found between trapezium and 1st metacarpal bone
saddle synovial joint
Type of joint found in the elbow
Hinge joint
Range of motion is described by?
Direction, Range and quality
Direction for range of motion includes
Flexion, extension, sidebending and rotation
range for range of motion?
is the actual measurements in degrees
quality for range of motion?
Smooth, ratcheting, restricted or exhibiting resistance to the motion induced.
End feel of range of motion?
Elastic
Abrupt: osteoarthritis or hinge joint
Hard: somatic dysfunction
Empty: Stops due to guarding (patient doesn’t allow the motion due to pain)
Crisp: involuntary muscle guarding as in pinched nerve
Static flexibility?
Maximal ROM a joint can achieve with an externally applied force
Flexibility?
ROM in a joint or group of joints or the ability to move joints effectively through a complete range of motion
Dynamic flexibility?
ROM an athlete can produce and speed at which he/she can produce it
What is stiffness
Reduced range of motion of a joint or group of joints
