26
What do muscle spindle cells do?
Monitor the stretch of a muscle and its rate of change in length
27
What do Golgi tendon organs do?
Detect and help the body respond to changes in muscle tension
28
What do Ruffini's end organs do?
Detect slow changes in the position of a joint
29
What are the four main kinds of proprioceptors?
Muscle spindle cells Golgi tendon organs Ruffini's end organs Pacinian corpuscles
30
Reciprocal Inhibition
Muscles on one side a joint relax to accommodate contraction on the other side
31
Biomechanics
The mechanical principles that directly relate to the body
32
Statics
Aspects of nonmoving (or virtually nonmoving) systems
33
Dynamics
Aspects of moving systems
34
Osteokinematics
The movement of bones around joint axes
35
Arthrokinematics
The small, generally unseen movements occurring between the articulating surfaces of joints
36
Force
Any influence that causes an object to undergo a certain change
37
Inertia
An object's resistance to a change in its state of motion or rest
38
Mass
The quantity of matter in an object
39
Torque
A force that involves rotation of an object around an axis
40
Momentum
The product of mass and velocity
41
Velocity
An object's rate of change in position
42
Lever
A simple machine that can amplify an applied force (effort) by converting it into torque
43
What are the three types of levers?
``` First class (Muscle-Joint-Load) Second class (Muscle-Load-Joint) Third class (Joint-Muscle-Load) ```
44
What is the function of a first class lever?
To balance power vs. speed and range of motion. It increases power (but as much as a second class lever) in exchange for speed/range of motion (but does not sacrifice as much as a second class lever).
45
What is the function of a second class lever?
To maximize power in exchange for speed and range of motion
46
What is the function of a third class lever?
To increase speed and range of motion in exchange for power.
47
Through what five points does the body's line of gravity run?
Ear, shoulder, hip, knee, ankle
48
Does the line of gravity run through the center of the shoulder joint, anterior or posterior?
Slightly anterior (greater trochanter))
49
Does the line of gravity run through the center of the hip joint, anterior or posterior?
Posterior
50
Does the line of gravity run through the center of knee, anterior or posterior?
Posterior
51
Does the line of gravity run through the center of the ankle, anterior or posterior?
Anterior
52
The myofascial core includes which diaphragms?
Respiratory, Abdominal, Pelvic
53
What are the muscles of the pelvic diaphragm?
pelvic diaphragm group, deep perineum group, urogenital group
54
What are the muscles of the abdominal diaphragm? And what the facial tissue are they connected to?
Abdominis rectus, transverse Abdominis, internal and external obliques, pyramidalis all connect to the thoracolumbar aponeurosis and lines alba
55
The myofascial core is held up by what group of postural supporters?
The mutifidi
56
What is the primary muscle of the respiratory diaphragm?
The diaphragm muscle
57
________-_______ posture occurs when the stabilizing muscles of the pelvis weaken and the pelvic bowl tilts forward.
Kyphotic-Lordotic
58
The _______ ______ involves excessive flex ion of the thoracic spine. This Posture causes the head to hyper extend in order to remain level.
rounded back
59
When _________ posture the pelvis tilts posteriorly, the lumbar spine flattens and the thoracic spine becomes hyperkyphotic
Swayback
60
Any sideways deviation of the spine is called ________.
Scoliosis
61
Genu Valgum is also known as ____ ____
Knock knee (think of knees stuck together by the gum in "valgum")
62
Genu Varum is also known as _________
Bowlegged
63
With genu valgum which muscles are tight and which are taut?
Taut TFL, Gluteus Maximus, vastus lateralis, biceps femoris Tight vastus medialis, gracilis, sartorius, semimembranosus, semitendinosus
64
How many "moments" are there to observe in the two phases of gait?
8
65
What are the 5 moments of the stance phase?
``` Heel strike Foot flat Midstance Heel-off Toe-off ```
66
What are the 3 moments of the swing phase?
Acceleration Midswing Deceleration
67
If client has an inappropriate Stance Phase, what muscles are likely implicated?
Iliopsoas Sartorious Hamstrings Plantar Flexion
68
A gait in which the trunk is pulled posteriorly is caused by weakness in what muscle?
Gluteus Maximus
69
A gait in which one side of the body leans during its stance phase while the opposite leg dips farther than normal at the beginning of the swing phase
Trendelenburg gait or gluteus medeus gait
70
A gait in which the body leans forward during the beginning of the stance phase is caused by weakness in the __________
Quadriceps
71
A gait in which the hips and the entire side of the body swing forward together, while the arm songs back, is called a ________ gait
Waddling
72
What two things occur if your hamstrings don't sufficiently engage during gait?
1. Genu recurvatum (knee hyperextends) | 2. Insufficient deceleration causes knee to snap into extension
73
In what type of gait do toes strike first? This is cause by weak ___________
``` Equinus gait Weak dorsiflexirs (tibiais anterior, extensor digitorum longus, extensor hallucis longus, peroneus tertius) ```
74
A fused hip results in ___-_______ gait. What are the main features of this gait?
Bell-clapper gait, which features excessive pelvic anterior and posterior tilting as well as flexion/extension of the lumbar spine during gait.
75
