Kinemetics

Question 0

______ is a study of combined art and science of human movement.

Answer 0

kinesology

Question 1

What are biomechanics?

Answer 1

application of physics to the human body

Question 2

Clinical Kinesiology refers to?

Answer 2

applying the study of kinesiology to the health care environment,

Question 3

What is a force that produce or resists movement?

Answer 3

kinetics.

Question 4

Kinematics are?

Answer 4

Types of movement without thinking about the forces acting on the surface.

Question 5

What motion occurs motion in a straight line?

Answer 5

Linear motion.

Question 6

An example of curvilinear motion is when the center of mass changes as we walk. True or False?

Answer 6

True.

Question 7

What is the movement of the bone segments that make up a joint called?

Answer 7

Osteokinematics.

Question 8

Arthrokinematics is a movement that occurs when?

Answer 8

Within and between joint surfaces.

Question 9

The sagittal plane divides the body into and what movements occur in this plane?

Answer 9

Divides the body into left and right with movements of ABDuction and ADDuction.

Question 10

What plane divides the body into anterior and posterior?

Answer 10

Frontal/ coronal.

Flexion and extension occur in this plane.

Question 11

Which plane allows lateral trunk flexion and what does it divide the body into?

Answer 11

The transverse plane divides the body into inferior and superior segments.

Question 12

Does ROM occur in artherokinematics or osteokinematics?

Answer 12

Osteokinematics.

Question 13

What is a type of motion that occurs around an axis?

Answer 13

Rotary motion.

It is the most common motion in the body.

Question 14

Name an example and how many degrees of freedom a triaxial axis have. Biaxial? Uniaxial?

Answer 14

Triaxial has 3 degrees of freedom (occurs in 3 planes) and an example is the hip (ball and socket joint)

Biaxial has 2 degrees of freedom and an example is Metacarpal Pharyngeal joints (saddle)

Uniaxial joints only have one degree of freedom and an example would be the elbow. (hinge joint)

Question 15

What end feel feels hard and why?

Answer 15

A hard end feel because it’s bone hitting bone.

Question 16

What is a soft end feel?

Answer 16

Muscle hitting muscle before the end range, limiting full ROM.

Question 17

What creates a firm end feel?

Answer 17

Ligaments refraining motions that could tear a joint.

Question 18

The distal segment is fixed to a surface during _______ kinematic chain.
Give an exercise example of this chain.

Answer 18

Closed kinematic chain.

Ex. squats. (feet are fixed to the floor)

Question 19

In an open kinematic chain, what is the distal segment capable of?Name an example exercise.

Answer 19

Free movement. not fixed to a surface.

Ex. bicep curls (even though hand is holding the weight, it is not fixed to a surface to remain stable).

Question 20

What is the type of joint responsible for providing stability?

Answer 20

Synarthrosis.

Ex. sutures in skull.

Question 21

Ampiarthrosis joints provide?

Answer 21

Stability and some motion for shock absorption.

Ex. vertebrae.

Question 22

What is a hip joint an example of? (joint wise)

Answer 22

Dianthrosis. (synovial) most common in the body.

Question 23

What are the four basic movements of arthrokinematic joints?

Answer 23

Rolling, sliding, spinning, compression.

Question 24

Describe a closed-packed position.

Answer 24

This is a position where the body is most stable and there is maximal surface area contact.
Ex. when the elbow is in full extension. (olcreon process is securely in the humerous.

Question 25

What position do joint surfaces not fit congruently?

Answer 25

Loose/ open packed position.
