| Answer |
|
|
| Proper body positioning reduces |
Possibility of fatigue and muscle strain |
| Proper body positioning promotes |
Efficient movement which increases strength, power, and pressure, decreases possibility of injury, enhances quality and effectiveness of massage, promotes energy or chi, increases career life span |
| Wrist problems |
Overuse can lead to problems such as carpal tunnel and osteoarthritis |
| Back problems |
Poor posture of the spine and excessive leaning over can lead to neck and shoulder problems as well as muscle spasms and problems of the back and spine |
| Arm problems |
Overuse of arms can lead to nerve entrapment and fatigue in the arms and shoulders |
| Main source of strength comes from |
Lower body not the arms and shoulders |
| Balance on both feet with |
Knees bent |
| Keep the back |
Straight and head up |
| Use the pelvis and torso to |
Provide leverage and strength needed to apply pressure |
| Elbows and hands should stay |
Close to the body |
| Shoulders and wrists should stay |
Relaxed |
| Used substitutes when |
More pressure or relief is needed |
| Keep wrists and hands |
In alignment with the movement |
| Avoid |
Small, repetitive movements |
| If injury or excessive strain occurs |
Rest until it heals |
| Adjust the table height to allow for |
Proper posture in relation to client size |
| Proprioception |
Special sense in the body that enables us to detect body position and movement |
| Proprioceptors |
Specialized nerve receptors found in joints, tendons, and muscles that sense body position |
| Muscle spindles |
Proprioceptors mostly found in the bellies of muscles, provide information about the length or change in length of skeletal muscles |
| Golgi tendon organs |
Proprioceptors located where muscles join with tendons, prevent tendons from being torn by inhibiting excessive muscle tension on tendons |
| First class levers |
Fulcrum is located between force and weight, allow variable mechanical advantage also called teeter-totter levers ex. triceps with elbow as fulcrum |
| Second class levers |
Weight is situated between the force and fulcrum, great for generating power, also called "nutcracker" or "wheelbarrow" levers ex. jaw |
| Third class levers |
Force is located between the weight and fulcrum, great for generating speed, also called "baseball bat" or "shovel of dirt" levers ex. hips |
| Muscle twitch |
Single contraction followed by relaxation |
| Tetanus |
Sustained contraction |
| Isometric contraction |
Muscle contracts but no change in length |
| Isotonic contraction |
Muscle contracts and changes length |
| Concentric contraction |
Muscle contracts and shortens |
| Eccentric contraction |
Muscle contracts and lengthens |
| Agonist |
Prime mover |
| Prime mover |
Muscle that is most responsible for movement |
| Synergist |
Muscle that helps perform a movement |
| Antagonist |
Muscle that works against another muscle and performs the opposite action |
