Neurotransmitters can be divided structurally into two categories: small nitrogen-containing neurotransmitters and neuropeptides discount 850mg glucophage. The small nitrogen- containing neurotransmitters are generally synthesized in the presynaptic termi- nal from amino acids and intermediates of glycolysis and the TCA cycle order 500 mg glucophage otc. They are retained in storage vesicles until the neuron is depolarized cheap glucophage 500 mg without a prescription. The cate- cholamine neurotransmitters (dopamine buy glucophage 850 mg fast delivery, norepinephrine, and epinephrine) are derived from tyrosine. Acetylcholine is synthesized from choline, which can be supplied from the diet or is synthesized and stored as part of phosphatidylcholine. Glutamate and its neurotransmitter derivative, -aminobutyric acid (GABA), are derived from -ketoglutarate in the TCA cycle. The synthesis of the neurotransmitters is regulated to correspond to the rate of depolarization of the individual neurons. A large number of cofactors are required for the synthesis of neurotransmitters, and deficiencies of pyridoxal phosphate, thiamine- pyrophosphate, and vitamin B12 result in a variety of neurologic dysfunctions. Brain metabolism has a high requirement for glucose and oxygen. Deficiencies of either (hypoglycemia or hypoxia) affect brain function because they influence adenosine triphosphate (ATP) production and the supply of precursors for neuro- transmitter synthesis. Ischemia elicits a condition in which increased calcium levels, swelling, glutamate excitotoxicity, and nitric oxide generation affect brain function, and can lead to a stroke. The generation of free radicals and abnormali- ties in nitric oxide production are important players in the pathogenesis of a variety of neurodegenerative diseases. Because of the restrictions posed by the blood-brain barrier to the entry of a vari- ety of substances into the central nervous system, the brain generally synthesizes and 881 882 SECTION EIGHT / TISSUE METABOLISM degrades its own lipids. Essential fatty acids can enter the brain, but the more common fatty acids do not. The turnover of lipids at the synaptic membrane is very rapid, and the neuron must replace those lipids lost during exocytosis. The glial cells produce the myelin sheath, which is composed primarily of lipids. These lipids are of a different composition than those of the neuronal cells. Because there is considerable lipid synthesis and turnover in the brain, this organ is sensitive to disorders of peroxisomal function (Refsum’s disease; interference in very-long-chain fatty acid oxidation and -oxidation) and lysosomal diseases (mucopolysaccharidoses; inability to degrade complex lipids and glycolipids). THE WAITING ROOM Katie Colamin, a 34-year-old dress designer, developed alarming palpita- tions of her heart while bending forward to pick up her cat. She also devel- oped a pounding headache and sweated profusely. One week later, her aerobic exercise instructor, a regis- tered nurse, noted that Katie grew very pale and was tremulous during exercise. The instructor took Katie’s blood pressure, which was 220 mm Hg systolic (normal, up to 120 at rest) and 132 mm Hg diastolic (normal, up to 80 at rest). Within 15 min- utes, Katie recovered, and her blood pressure returned to normal. The instructor told Katie to see her physician the next day. The doctor told Katie that her symptom complex coupled with severe hyperten- sion strongly suggested the presence of a tumor in the medulla of one of her adre- nal glands (a pheochromocytoma) that was episodically secreting large amounts of catecholamines, such as norepinephrine (noradrenaline) and epinephrine (adrena- line). Her blood pressure was normal until moderate pressure to the left of her umbilicus caused Katie to suddenly develop a typical attack, and her blood pressure rose rapidly. She was immediately scheduled for a magnetic resonance imaging (MRI) study of her adrenal glands. Ivan Applebod’s brother, Evan Applebod, was 6 feet tall and weighed 425 pounds. He had only been successful in losing weight once in his life, in 1977. Evan’s weight was not usually a concern for him, but in 1997 he had become concerned when it became difficult for him to take walks or go fishing because of joint pain in his knees. He was also suffering from symptoms suggestive of a peripheral neuropathy, manifest primarily as tingling in his legs.

For example discount glucophage 500mg on line, there is a rapid transition in fluid flow between turbulent and nonturbulent flow cheap glucophage 850mg free shipping. The fluid does not like to remain a mix of the two states generic 850mg glucophage with visa; in other words buy cheap glucophage 500mg on-line, the fluid is attracted to one state or the other with varying strengths. This concept of attractors can be used to understand motor control. An example in human gait is walking speed, in which not all velocities have equal preference from standing to maximum running. The chaotic attractor of normal adult walking velocity tends to be strong, between 100 and 160 cm/s. If a person cannot walk close to 100 cm/s, they will often walk at a comfortable speed, then stop and wait for a while, then walk at a natural speed, then stop again. Standing and not moving is another velocity attractor. On the other hand, if an individual has to go faster than 160 cm/s, they typically break into a running gait pattern with a pre- ferred comfortable speed between 250 and 300 cm/s. For speeds around 200 cm/s, most individuals alternate between running and walking because these speeds are more comfortable than trying to stay at an in-between level of not quite walking and not quite running comfortably. Most adults expe- rience and respond to these velocity attractors by altering their speed to be in one of the three stated gait patterns. Another feature of these attractors is that they may be very stable or somewhat unstable. An example of an unstable attractor is the body position taken in the middle of a jump. This position is an unstable attractor because the body cannot stay this way for long before it has to move to the next at- tractor, which is the response for landing. Understanding and defining these attractors in motor control can be very helpful in understanding response to growth and development as well as responses to treatment. To clarify the understanding, the term chaotic attractors is used in the remaining text to define these attractors, although the more classic mathematical term used in chaos theory is strange attractors. These two states of heart rhythms are both stable because they are not easily changed without significant ex- ternal force. The concept of dynamic systems theory for motor control also aids under- standing of how individuals end up doing similar tasks with variable but sim- ilar patterns. For example, if a walking child is asked to pick a cookie up off the floor, the pattern used likely will be either predominantly bending at the hip and spine with the knees straight, or flexing the hips and knees keeping the spine straight. With all the muscle and joints available, there are almost endless variations of how a task can be accomplished; however, there is a chaotic attractor toward two or three patterns of motion to accomplish a given task. The Cause of Chaotic Attractors Understanding the anatomic or mechanical origin of these chaotic attractors is very difficult, and based on chaos theory, there are too many variable inputs to the system to specifically define these attractors; therefore, they are usu- ally defined as a region. For example, a chaotic attractor draws normal human walking velocity to a relatively stable attractor of around 100 to 160 cm/s. The strength and definition of this attractor are related to the length and mass of the legs, the speed of muscle contraction, the speed of nerve con- duction, and the environment. It is impossible to define the exact center of this chaotic attractor because it is based on many things, from the environ- ment to the individual’s behavior and mood. Using this concept of dynamic systems theory, a framework exists for understanding why different movement patterns develop in children with CP. For example, children with diplegic pat- tern involvement frequently develop a crouched gait at adolescence. De- pending on what treatment is chosen, the child may continue in the crouched pattern or may revert to a back-kneeing pattern. This gait change is an ex- ample of the chaotic attractor organizing the child’s motion. The important thing for the surgeon to understand is that the system does not want to organ- ize around normal knee extension, which is the physician’s treatment goal. Another important concept arising from dynamic systems theory is that the control system is self-organizing and there is no need for a CPG or ge- netic encoding or learning. The example from physics is that the fluid does not need genes, learning, or software to decide to reorganize from turbulent to nonturbulent flow.

However glucophage 500 mg on-line, scientific evidence has been accumulating in recent years that dispels this contention and supports the effectiveness of strength training for improving motor function in CP as well as in other neuromotor disorders 850mg glucophage otc. Muscle strength is related to motor performance and should be an integral part of a rehabilitation program that addresses other impairments which inhibit motor performance in this population cheap 500 mg glucophage otc, such as muscle–tendon shortening order glucophage 850 mg without prescription, spasticity, and coordination deficits. It has been shown that even highly functional children with spastic CP are likely to have considerable weakness in their involved extremities com- pared to age-related peers, with the degree of weakness increasing with the level of neurologic involvement. In the ab- sence of voluntary control, strength training is more problematic, but may be facilitated by the use of electrical stimulation or by strengthening within synergistic movement patterns. However, strengthening is only justifiable if the ultimate goal is to improve a specific motor skill or function. Therefore, a child with little or no capacity for voluntary muscle control is unlikely to experience substantial functional benefits from a strength-training program. Most ambulatory children with CP have the capacity to strengthen their muscles, although poor isolated control or inadequate length in the ankle dorsiflexor or the hamstring muscles may limit progress in some patients. Nonambulatory children may also experience improvements in their ability to use their upper extremities, transfer more effectively, or engage more actively in recreational and fitness activities. Invasive procedures such as muscle–tendon lengthening, selective dorsal rhizotomy, intrathecal baclofen pump implantation, or botulinum toxin injections may improve muscle length and/or control so that muscles can then be strengthened more effectively. In turn, strength training may serve to augment or prolong the outcomes of these procedures. To participate in a strength-training program, the child must be able to comprehend and to consistently produce a maximal or near-maximal effort. Children as young as 3 years of age may be capable of this, but waiting to augment the program until the child is age 4 or 5 years is more realistic. Rehabilitation Techniques 807 Motivational and attentional factors can also affect a program’s success. Family compliance with the treatment schedule and protocol is also critical. The same physiologic principles that underlie the development of muscle strength apply whether or not a person has CP. Load is the stimulus for increasing strength and it should be close to an individual’s maximum to achieve measurable gains. In practical terms, this would mean that a person should be able to lift a specified load two to three times before experiencing fatigue or a decrement in performance. Data on the specific treatment regi- mens to differentially train for strength, endurance, or power in this popu- lation, or which muscles can and should be strengthened to impart the great- est functional benefits, are not yet available specifically for CP, although useful guidelines may be found in the literature. For example, if the focus were on strengthening, an opti- mal program would be to use high loads with a low number of repetitions (3 to 8) arranged in multiple sets with a rest between each set. In contrast, if the therapist is more interested in improving muscle endurance, the load does not need to be quite so high, but repetitions should be greater (8 to 20) be- fore resting. As the patient improves, the load and/or the number of repeti- tions can be increased depending again on the therapist’s goal. If the goal is to try to increase strength, the recommended frequency of sessions is three times a week. It seems logical that muscles across the joint from those that tend to be spastic are good candidates for strengthening. In spastic CP, for example, one might consider strengthening any or all of the following: elbow extensors, forearm pronators, wrist extensors, hip extensors and abductors, knee ex- tensors, and ankle dorsiflexors. However, weakness can be present in other muscles that may also disrupt performance, such as the ankle plantar flexors or hip flexors, which are important power producers in gait. Both absolute and relative strength across a joint should be considered when designing protocols to avoid exacerbating muscle imbalance and contractures. Sample isotonic and isokinetic training programs are shown in Tables R1 and R2.
