Motion Dynamics Flashcards
Active Range of Motion
Patient does the moving
Passive Range of Motion
Doctor does the moving
Compare and contrast passive and active ROM?
Passive ROM> Active ROM
What is the elastic range?
The range between the physiologic barrier (limited by active motion) and the anatomic barrier
Describe the coronal plane.
Bisects the body into front and back planes
Describe the Sagittal plane.
Bisects the body into right and left halves
Describe the Horizontal/transverse plane.
Divides the body into superior and inferior halves.
What is the ROM around the sagittal plane?
Flexion and Extension
Flexion is bending forward
Extension is bending backwards
What is the ROM around the Coronal plane?
Abduction/Adduction
What is the ROM around the transverse plane?
Rotation
What are the 3 types of joints?
Fibrous- skull articulations
Cartilaginous- discs between vertebrae
Synovial- extremities (6 different types)
What are the 6 types of synovial joints? Give an example for each.
Pivot Joint- Between C1 and C2 vertebrae
Hinge Joint- elbow
Saddle Joint- between trapezium carpal bone and the 1st metacarpal bone
Plane Joint- between tarsal bones
Condyloid Joint- between radius and carpal bones of the wrist
Ball and Socket Joint- hip
What are the 3 characteristics that make up motion. In other words, motion has ____, _____, and ____
Direction, Range, and Quality
Direction- flexion, extension, sidebending, and rotation
Range- actual measurements in degrees
Quality- smooth, ratcheting (Parkinson’s), restricted (contracture or somatic dysfunction)
Which portion of the spine has the greatest range of motion?
Cervical Spine
What is abnormal in patients suffering from Ehler-Danlos Syndrome?
Collagen dysfunction, leading the patient to have elastic skin, overly flexible joints, and bruises easily
