Miscellaneous Flashcards
ATP-PC System
- used for ATP production during high intensity, short duration exercise
- Phosphocreatine decomposes and releases a large amount of energy that is used to construct ATP
- process occurs almost instantaneously , allowing for ready and available energy needed by the muscles.
- Both ATP and PC are stored directly within the contractile mechanisms of the muscle
anaerobic glycolysis
- thie energy system is a major supplier of ATP during high intensity, short duration activities such as sprinting 400 or 800 meters. stored glycogen is split into glucose, and through glycolysis, split again into pyruvic acid. The energy released during this process forms ATP.
The process does not require oxygen - anaerobic glycolysis results in the formation of lactic acid, which causes muscular fatigue
-50% slower than the PC System can can provide a person with 0-40 seconds of muscle contraction.
Aerobic Metabolism
- is used predominantly during low intensity, long duration exercise such as running a marathon.
- the oxygen system yields by far teh most ATP, but it requires several series of complex chemical reactions
- provides energy through the oxidation of food.
- the combination of fatty, acids, AA, and glucose with oxygen releases energy that forms ATP. this system will provide energy as long as there are nutrients to utilize
Free nerve ending location & distribution
- joint capsule, ligaments, synovium, fat pads
- all joints
Free Nerve endings sensitivity
- One type is sensitive to non-noxious mechanical stress; other type is sensitive to noxious mechanical or biochemical stimuli
Golgi Ligament Endings Location, distribution
- ligaments- adjacent to ligaments’ bony attachment
- majority of joints
Golgi Ligament Sensitivity
- Tension or stretch on ligaments
Pacinian Corpuscles location and distribution
- fibrous layer of joint capsule
- all joints
Pacinian Corpuscles Sensitivity
- High FReq vibration, acceleration, and high velocity changes in joint position
Ruffini Endings Location and distribution
- Fibrous layer of joint capsule
- Greater density in proximal joints,particularly in capsular regions
Ruffini Endings Sensitivity
- Stretching of joint capsule; amplitude and velocity of joint position
indications for Mobilization
- passive movement technique designed to improve joint function
- indication: restricted joint mobility, restricted accessory motion, desired neurophysiological effects
Contraindications for mobilization
- active disease, infection, advance osteoporosis, articular hypermobility, fracture, acute inflammation, muscle guarding joint replacement
Grades of Movement
- Grade I
- small amplitude movement performed at the beginning of range
Grades of Movement
-Grade 2
- Large amplitude movement performed within the range , but not reaching the limit of the range and not returning to the beginning of range
Grades of Movement
-Grade 3
- Large amplitude movement performed up to the limit of range
Grades of Movement
-Grade 4
- Small amplitude movement performed at teh limit of range
Grades of Movement
-Grade 5
- Small amplitude, high velocity thrust technique performed to snap adhesions at the limit of range
mobilization on a convex surface moving on a concave surface
- Roll and slide occur in the opposite direction
- Mobilizing force should be applied in the opposite direction of the bone movement
Type I Muscle Fibers
- Aerobic
- Tonic
- slow twitch, slow oxidative
- low fatigability
- extensive blood supply
- small fibers
- examples marathon, swimming
Type II Muscle Fibers
- Anaerobic
- Phasic
- Fast twitch
- fast- glycolytic
- High fatigability
- large fibers
- Examples: high jump, sprinting
DIsease- modifying antirheumatic Agents
- Disease- modifying antirheumatic drugs slow or halt the progression of rheumatic disease. they are used early during the disease progress to slow the progression prior to widespread damage of teh affected joints. They act to induce remission by modifying the pathology and inhibiting the immune response responsible for rheumatic disease
Indications: rheumatic disease, preferably during early tx
corticosteroid
- glucocorticoid provide hormonal, anti-inflammatory, and metabolic effects including suppression of the articular and systematic diseases. these agents reduce inflammation in chronic conditions that can damage healthy tissue through a series or reactions.
- Vasoconstriction results from stabilizing lysomal membranes and enhancing the effects of catecholamines
- -Indications: replacement therapy for endocrine dysfunction, anti-inflammatory and immunosuppresive effects; tx of rheumatic, respiratory and various other disorders
Nonopiod Agents
- nonopiod agents provide analgesia and pain relief, produce anti-inflammatory effects, and initiate anti-pyretic properties. these drugs promote a reduction of prostaglandin formation that decreases the contractions, lowers fever, and minimizes impulse formation of pain fibers
- Indications: mild to moderate pain of various origins, fever, HA, muscle ache, inflammation, primary dysmenorrhea, reduction of risk of myocardial infarction
