What are the two parts of MMT?
|
1. force of gravity
2. manual resistance |
|
|
Strength
|
maximal amount of tension or force that a muscle can voluntarily exert in one maximal effort
|
|
|
Torque Equation
|
T=F X d
|
|
|
In a concentric contraction, which way do the origin and insertion move?
|
Towards each other
|
|
|
In an eccentric contraction, which way do the origin and insertion move?
|
Opposite each other
|
|
|
Overwork
|
temporary or permanent loss of muscular strength in an already weak muscle due to excessive vigorous activity
|
|
|
full range
|
muscle changing from a position of full stretch and contraction to a position of maximal shortening
|
|
|
middle range (mid range)
|
A portion of the full range between the midpoint of the outer range and the midpoint of the inner range
|
|
|
Synergist
|
a muscle that contracts and works along with the agonist to produce the desire movement
|
|
|
Non-pathological factors affecting strength
|
1. age
2. gender 3. size of muscle 4. type of contraction 5. speed of muscle contraction 6. Joint position 7. Diurnal Variation 8. Temperature 9. Fatigue |
|
|
As we age, what happens to muscle?
|
Muscle mass starts to deteriorate. Muscle fibers decrease in size and number.
|
|
|
TRUE OR FALSE: Muscle with a smaller cross-sectional area of a muscle are stronger than muscles with a large cross-sectional area.
|
FALSE
|
|
|
When contracting concentrically and eccentrically, what is the best speed to produce maximal tension?
|
Concentric-slower speeds
Eccentric-faster speeds |
|
|
List from strongest to weakest types of muscle contractions
|
Eccentric>isometric>concentric
|
|
|
What is the optimal angle of pull of muscle?
|
90 degree angle.
|
|
|
In length-tension relationships, where do muscles develop the most tension?
|
The greatest amount of tension is developed when the muscle is stretched to the greatest length possible within the body. A muscle contracts with more force when it is stretched than when it is shortened.
|
|
|
What position of joints is there maximal tension in the joint capsule and ligaments?
|
Closed-packed positions
|
|
|
Resting position
|
the position of least stress on the joint, least congruency of joint surfaces, and the greatest laxity of the capsule and ligaments (or maximum loose-packed position)
|
|
|
List the contraindications for MMT
|
1. pain
2. pain of unknown origin 3. Fracture 4. Inflammation or tissue infiltration 5. Patients with severe cardiovascular or respiratory disorders or diseases with severe acute symptoms 6. Inflammatory neuromuscular diseases |
|
|
List the precautions for MMT
|
1. Hypertension
2. Decreased sensation 3. Chronic disabilities 4. Osteoporosis 5. Over open wounds 6. Skin diseases 7. Upper motor neuron lesions 8. Abdominal surgeries/hernias 9. Conditions where fatigue may exacerbate patients symptoms 10. Situations where overwork may exacerbate patients symptoms 11. Patients at risk for cardiovascular problems. |
|
|
What side do you test first when doing MMT?
|
The unaffected side first
