What is the most common type of spinal loading during daily activities
compression
Lateral deviations in spinal curvature are called
scoliosis
Which type of exaggerated curve is often caused by osteoporosis
kyphosis
Cause of a stiff neck?
Levetor scapula
Which plane is shoulder extension?
Sagittal
Tennis Elbow
Lateral epicondylitis – extension
Golfers elbow
Medial epicondylitis – flexion
5 type of forces
~Compression ~Tension ~Shear ~Bending ~Torsion
Kinetics
The stuidy of forces associated with motion
Kinematics
Study of the description of motion, “appearance”
Kinesiology
Study of human movement
Sagittal plane
-movements-
Divides body into left and right
-Flexion/ extension-
Frontal/Coronal plane
-movements-
Divides body into front and back
- Adduction/abduction-
- Ulnar and radial deviation-
- Inversion/Eversion-
- Lateral flexion-
Transverse/Horizontal plane
-movements-
Divides body into top and bottom
- rotations-
- Wrist pronation/supination-
- Horizontal abduction/adduction-
How many bones in the body?
206
177 are involved in movement
Short bone function?
Shock absorption
Concentric Contraction
- muscle force is sufficient to overcome a resistance and move the body segment, shortening of the muscle
- muscle force is greater than external force
Eccentric Contraction
- when a muscle lengthens as it gives in to an external force that is greater than the contractile force it is exerting
- muscle controls movement, muscle is pulling but another force is causing the movement
- gravity lowering arms but slowly lowering arms
Isometric/ static Contraction
- muscle force is equal to external force, thus no movement
- occurs when antagonist muscles contract with equal strength and when a muscle is held against another force
Isotonic Contraction
- equal tension (one tone), tension remains constant while muscle shortens or lengthens
- can be concentric or eccentric
Isokinetic Contraction
- equal speed, max muscle effort at the same speed
- can be concentric or eccentric
Agonist
- movers, directly responsible producing a movement, performs concentric movements
- prime movers (large impact on movement, the boss) assistant movers (only help when needed)
Antagonist
- role played by a muscle acting to slow or stop a movement
- most active to slow a movement (at the end of the movement)
Woles law ?
Bone strength increase and decreases as the function forces on the bones increase and decrease
