Although I still grumble when I get up at night and find myself shuffling along buy toradol 10mg online sports spine pain treatment center hartsdale ny, I have other things to think about when I 14 living well with parkinson’s wake up in the morning effective 10 mg toradol ayurvedic treatment for shingles pain. Does this mean that I have totally accepted and adjusted to the fact that I have Parkinson’s? I don’t like Parkinson’s, but I’ve got it, and I’ve proved to myself that I can handle it and still lead a productive life. As time has gone by, my frustrations have changed as my Par- kinson’s has changed. Now when I have a "freezing" or a dizzy spell, I know that in a few minutes it will pass. I still try to do as many things as I did in the past, but I have to make allowances. As with most things, it seems that with Parkinson’s, what goes around comes around. Even when I felt somewhat energetic and capable, I still noticed little, sneaky symptoms cropping up, like the incident with the plate of cookies. Then when I lost hope and was almost ready to give up, things improved and I started the cycle all over again. I haven’t given up yet, and I con- sider myself fortunate that I’ve had very little tremor. CHAPTER 3 Coping with Frustration: Practical Suggestions for Everyday Living If my brain can conceive it, And my mind can believe it, Then I can achieve it. The most ordinary tasks and activities become difficult and taxing, especially toward the end of a dose of medication. This interference in everyday activi- ties produces deep feelings of frustration in the person with Par- kinson’s—feelings that I, for one, have never been able to over- come entirely. However, I have found ways to minimize the problems that cause these feelings, and they are worth sharing with you. At the outset, you should know that current medications and therapies enable people with Parkinson’s to have a normal life and 15 16 living well with parkinson’s live it more comfortably than ever before. While there is no way to eliminate all the frustrations you will experience with Parkin- son’s disease, there is a positive approach to coping, if you will make that choice. On the right side of my body, where my symptoms had started, I moved where I wasn’t supposed to move and didn’t move where I expected to move. In addition, I experienced strange, un- explained sensations in my right arm and leg. Later, the keys to our home and car "didn’t work" for me, although they still worked for Blaine. Manufacturers seemed as if they were out to get me, with bottles covered by child-proof caps, cereal boxes and dry goods sealed with unyield- ing glue, and other containers double-locked with tough, extra packaging seals. To make matters worse, I began to trip on steps and curbs that I could see perfectly clearly. I knew that if I were to cope with these new problems, I would have to under- stand more about what was happening to me. Feldman and the Parkinson’s Program at Boston Medical Center and learned more about Parkinson’s dis- ease, I understood better. Dopamine is a substance produced by the body that is necessary for carrying messages within the brain. A lowered level of dopamine ultimately permits too many muscles to contract at once. One muscle starts pushing hard against another, each muscle canceling the action of the other, and this abnormal pushing of muscle against muscle is very fatiguing. My body was exhausting itself by trying to compensate for the changes taking place and by fighting the abnormal movements. Armed with this knowledge, Blaine and I solved one of my early problems: tripping. Blaine had started to watch me very closely, and he noticed that my right foot was always the one that tripped.

Some people with Parkinson’s find that they can manage a regular tooth- brush more easily if they put a large discount 10 mg toradol visa arizona pain treatment center phoenix az, foam-rubber hair curler or a rubber bicycle handle grip over the handle of the brush buy toradol 10 mg on-line heel pain treatment webmd. In the bathroom, unbreakable plastic or paper cups are safer than glass or ceramic. If you experience difficulty in bathing with your washcloth, try using a terrycloth mitt, a long-handled brush, or a sponge. Hanging soap-on-a-rope on a faucet will keep the soap from getting too far away from you. To prevent slipping in the wet tub, wear mesh, rubber-soled shoes when you bathe, and use a rubber mat on the floor of the tub or the shower stall when you shower. Instead of a small, loose bath rug outside your tub or shower stall, prevent tripping by installing wall-to-wall carpet in the bathroom. Are you aware of all the special equipment for home use that is available at your nearest medical supply store? Ask the salesper- son to show you equipment that’s useful for people with Parkin- son’s. Did you know that some major department stores also have catalogs with special aids and special clothing? If you have difficulty speaking loudly enough, you may want to obtain a device from the telephone company that will amplify your telephone voice. Cordless phones are helpful because they have 22 living well with parkinson’s no wires to trip over. Another useful appliance in the bedroom is a radio or a cassette player that can be set to turn itself off: sooth- ing music will help you fall asleep. You can get an amplifier for your telephone and a closed-caption device for your television set. You can help yourself by using a small, rolling cart to carry cleansers, implements, and other items through the house. An apron with large pockets is also useful for carrying items back to their proper places when you tidy up. If you use a walker, you can attach a bicycle basket to it to carry items in the house. When you prepare a meal, cook double or triple the amount of food, and freeze the extra portions for future meals. Cook sev- eral items side by side in the same steamer pot—you’ll have fewer pots to wash. Even leftovers or frozen, precooked foods can be added next to items that are already steaming. To write shopping lists, notes, and letters, try using a clipboard to keep the paper steady. If you notice that your handwrit- ing decreases rapidly in size (a common problem among people with Parkinson’s), try this trick: stop writing, pick up your arm, wiggle your fingers, and start writing again. You may want to shop during off-hours—early in the morning, for example—to avoid crowds and lines. Just as there are many ways to make life easier in the home, you can also reduce frustration in the car. First you must ask coping with frustration 23 yourself, can you continue to drive? Before I started taking med- ication, I noticed (after learning how to make the key open the car door) that I was taking longer to make turns. I couldn’t exert enough pressure on the seat adjustment lever while pulling up at the same time, to move the seat to a comfortable position for driving. Fortunately, after I started taking medication, I was able to drive safely, but I have put restrictions on myself. I don’t drive long dis- tances because doing so causes my muscles to tighten up and hurt. I also don’t drive if I don’t feel well, the weather is bad, or the roads are icy. Now I can adjust the car seat easily because our new car has power seat adjustments, a very good option for people with Par- kinson’s.

The major arterial trunks supplying the radicular arteries at each level are the following: Vascular Anatomy of the Spinal Cord 17 FIGURE 1 discount toradol 10 mg without prescription pain solutions treatment center hiram. Selective intercostal artery injection showing longitudinal pre- transverse anastomosis between segmental arteries (open arrow) order toradol 10 mg with amex bayhealth pain treatment center dover de. Vertebral arteries, ascending cervical branch of the thyro- cervical trunk, deep cervical branch of the costocervical trunk, oc- cipital branch of the external carotid artery (ECA), and ascending pharyngeal branch of ECA. Branches of the costocervical trunk, internal thoracic branch of the subclavian artery, supreme intercostal branch of the aorta, and intercostal branches of the aorta. Lumbar branches of the aorta, middle sacral branch of the aorta, lateral sacral branches of the internal iliac arteries, and il- iolumbar branch of the common iliac arteries. At each of the 31 levels, each segmental artery supplies blood to the dorsal and ventral nerve roots, thereby being given the desig- nation "radicular" artery. At some levels, the segmental artery sup- plies blood not just to the nerve root but also beyond, to the spinal cord, via branches connecting either to the pial/coronal arterial net- work, or directly to the anterior spinal artery. In the former condi- tion these segmental arteries are named "radiculopial," and in the latter "radiculomedullary. Connecting these two networks is the pial/coronal (centripetal) network of small arteries. Some experts consider the paired posterior spinal arteries to be part of the pial/coronal network, representing more dominant craniocau- dally oriented channels. According to this definition, those segmental arteries providing supply to the posterior spinal arteries are more ac- 18 Chapter 1 Spine Anatomy curately designated as radiculopial rather than radiculomedullary. The flow in the spinal arteries, anterior and posterior, is bidirectional, depending on the dominant medullary artery at each level, as well as the time needed for the aortic systolic pulse wave to reach each radicu- lomedullary or radiculopial artery (more distal arteries will experience the aortic systolic pulse wave later, which also contributes to bidirec- tional flow). Radicular Arteries At each of the 31 levels, the spinal/segmental artery provides branches to the dorsal and ventral nerve roots, after giving off branches to the paraspinous musculature, vertebral body, and dura. The only excep- tion is the C1 level, where there may be congenital absence of the radic- ular branches. Under normal physiological circumstances, the radicu- lar branches are usually too small to be seen angiographically. Radiculopial Arteries The radiculopial arteries supply the nerve roots (via radicular branches), then run ventral to either the dorsal or the ventral nerve root to supply blood to the pial/centripetal (vasa corona) network. These arteries do not supply the anterior spinal artery (ventral axis) di- rectly. They do have anastomoses with pial branches of the anterior spinal artery, however. The dorsal radiculopial arteries (called dorsal radicu- lomedullary arteries by some authors) are more important, and are the ones referred to as the radiculopial arteries henceforth in this chapter. On average, there are 3 to 4 dorsal radiculopial arteries in the cervical region, 6 to 9 in the thoracic region, and 0 to 3 in the lumbosacral region. Radiculomedullary Arteries The radiculomedullary arteries provide the only segmental supply to the ventral spinal axis (anterior spinal artery) and are the dominant source of supply to the cord over several functional segments.

Vascular Anatomy of the Spinal Cord 19 After giving off their radicular branches to the nerve roots, they run along the ventral surface of the nerve root, occasionally giving off a pial collateral, then supply the anterior spinal artery. On average, there are 2 to 4 (ven- tral) radiculomedullary arteries in the cervical region, 2 to 3 in the tho- racic region, and 0 to 4 in the lumbosacral region. Classically, two radiculomedullary arteries have received special attention: the arteries of the cervical and lumbar enlargements. The artery of the lumbar en- largement is also known as the artery of Adamkiewicz (Table 1. In 75% of patients, the artery of Adamkiewicz arises between T9 and T12, more commonly on the left. When its origin is above T8 or below L2, there is another major contributor to the anterior spinal artery ei- ther caudally or cranially. In 30 to 50% of cases, it also gives a major contribution to dorsolateral pial system (paired posterior spinal arter- ies) (Figure 1. The connection of the radiculomedullary artery to the ventral spinal axis is Y shaped in the cervical area because the artery does not have FIGURE 1.

The single ventral spinal axis (anterior spinal artery) is continuous from the basilar artery to the artery of the filum terminale.
