Joint Congruency
|
Loose packed- Ligaments are lax, Minimal congruency between articulating surfaces of bone, Less likely to be injured, Allows for joint mobilization
Closed packed- Joints have Max contact, Joint tightly compressed, Joint difficult to distract or separate, More likely to injure |
|
Accessory motions
|
Roll, Glide, Spin
Convex-Concave Rule- A concave surface will moved on a fixed convex surface in the same direction as the body segment is moving; A convex surface willl move in the opposite direction of the body segment's movement |
|
Osteokinematics
|
Movement of bone around a joint axis, it's what we see
|
|
Arthrokinematics
|
Movement at the joint surface btw the articulating surfaces, we do not see this movement but must be present for individual to have full movement at that joint
|
|
Muscle Characteristics
Irritability |
ability to receive and respond to a stimulus
(Stimulate it and it will respond-Irritability) |
|
Muscle Characteristics
Contractility |
ability to shorten, produce tension
(stimulate it and it will shorten-contractility) |
|
Muscle Characteristics
Extensibility |
ability to be stretched beyond normal resting length
(stretch a muscle and it will lengthen-extensibility) |
|
Muscle Characteristics
Elasticity |
ability to return to normal length; elongate/lengthen
(remove the stretch/stimulus and it will return to normal resting position-elasicity) |
|
Active Insufficiency
|
when a muscle reaches the point where it cannot shorten any further, it occurs to the muscle contracting, multi joint mm cannot produce full range of motion at all of the joints they cross simultaneously
(ONLY in multi joint mm) |
|
Passive Insufficiency
|
When a mm CANNOT be elongated ANY further without damage to its fibers, it occurs to the mm producing the motions opposite of the mm contracting
|
|
Isometric
|
contractile mechanisms are activated but no change in mm length, static or holding contraction, no joint movement, relationship of O & I remains, can occur in ANY plane
Ex: sucking in stomach |
|
Concentric
|
A shortening mm contraction, O & I move closer together, occurs against gravity OR gravity eliminated plane, is an acceleration activity; resistance constant; velocity varies
Ex: elbow flex/extension on horizontal plane |
|
Eccentric
|
A lengthening contraction; acts as a brake, O & I move farther apart, external force (gravity, weight) causes the motion; motion occurs ONLY when gravity is a factor, CANNOT occur in GE plane
Ex: letting the arm down slowly so your muscles are still working |
|
Agonist (prime mover)
|
produces the movement, is primarily responsible for the motion of the body part, contracts actively
|
|
Agonist (assisting mover)
|
contributes to the motion, assisting or prime depends on: size, angle of pull, leverage, contractile potential; A muscle that assists but is not as effective may be called assisting mover
|
|
Antagonist
|
the muscle that has the OPPOSITE anatomic action of the agonist, usually antagonist muscle is relaxed while agonist is working, antagonist MUST be able to be lengthened to allow agonist to shorten
|
|
Agonist or Antagonist
|
Whether a muscle is an agonist, antagonist, etc is not absolute,
it varies with the position of the body, the resistance and the actions being performed |
|
Stabilizer (fixator)
|
muscle group provides support, makes firm; provides a foundation for agonist, allows agonist to work more efficiently, PROXIMAL to agonist, determined once you know the agonist
|
|
Neutralizer
|
a contraction to Rule Out Unwanted Motion, remember a muscle wants to produce all of its actions at all of the joints it crosses, neutralizes the unwanted action (*Ex: biceps-flexes&supinates so pronator teres could be neutralizer)
again determined by the motion desired and the agonist |
|
Angle of pull
|
O&I and relationship of muscle to joint (where it crosses the joint) will tell you what its action is going to be
Ex: Ant-Flexion Wrapped-Rotation Posterior-Extension etc |
|
Reversal of Action
|
Mm move origin toward the insertion
Ex: chin up |
|
End Feel- Soft
|
Normal- Soft tissue approximation (Ex: Elbow flexion)
Abnormal- Occurs sooner or later in the ROM than usual OR in a joint that normally has a firm or hard end feel; feels boggy (Ex: edema, synovitis) |
|
End Feel-Hard
|
Normal-Bone contacting the other bone at the joint (Ex: Elbow extension)
Abnormal- Occurs sooner or later in the ROM than usual OR in a joint that normally has a firm or soft end feel; bony grating or bony block is felt (Ex: Bony growth or spur, osteoarthritis) |
|
End Feel- Firm
|
Normal- Muscular, Capsular, or ligamentous stretch (Ex: Hip flexion with knee extension, finger MCP extension, forearm supination, etc)
Abnormal- Occurs sooner/later than normal in the ROM OR in a joint that normally is hard/soft (Ex: increased mm tone, shortening of mm, ligaments, or fascia) |
|
End Feel-Empty
|
ALWAYS ABNORMAL- No real end feel but pain prevents reaching end of the ROM; no resistance but patient in pain
(Ex: Acute joint inflammation, Fracture, Bursitis, Abscess) |
|
Tenodesis
|
Considered the functional use of passive insufficiency
|
|
Kinematic Chains- Closed
|
Distal segment of extremity is fixed, movement at one joint will cause movements at all other joints in the extremity
|
|
Kinematic Chains- Open
|
Distal segment is not fixed, it is free to move, does not cause motion at other joints in the extremity
|
|
Laws of Motion- Law of inertia
|
an object at rest tends to stay at rest, and an object in motion tends to stay in motion
|
|
Laws of Motion- Law of acceleration
|
the amount of acceleration depends on the strength of the force applied to the object; acceleration is inversely proportional to the mass of an object. A force with more mass requires more force to move and will not accelerate as quickly
|
|
Laws of Motion- Law of action-reaction
|
for every action there is an equal and opposite reaction
|

Area, Angle, & Time
|
|
Stability of body depends on?
|
Height of center of gravity above bas of support, size of bas of support, location of the gravity line within the base of support
|
|
Forces- Linear force
|
2 or more forces acting along the same line, can increase the force; add together, can cancel out the force
|
|
Forces- Parallel forces
|
occur in the same plane and in the same or opposite directions
|
|
Forces- Concurrent Forces
|
2 or more forces act from a common point but pull in divergent directions
|
|
Forces- Resultant Force
|
The net effect of two concurrent forces, USE A PARALLELOGRAM to represent, the diagonal line is the resultant force
(the two forces may not be equal) |
|
Forces- Force couple
|
when 2 forces act in equal but opposite direction resulting in a turning effect
|
|
Pulleys, wheel & axle, Inclined plane
|
Pulley- change direction (fixed), alter magnitude of force
Wheel & axle- wheel larger, less effort Inclined plane-Longer less effort |
