Meningococcal disease. Meningitis has seen a resur- gence in the U.S. Approximately 2,600 people in the U.S. are diagnosed with meningitis, and about 10 percent to 15 percent of those people die. Meningitis is a viral or bacterial infection of the fluid of a person’s spinal cord and the fluid that surrounds the brain. It is spread through the exchange of respiratory and throat secretions (i.e., coughing, kissing). Symptoms include high fever, headache and stiff neck, which can develop over several hours, or they may take one to two days to appear. Other symptoms may include nausea, vomiting, discomfort looking into bright lights, confusion and sleepiness. All young people ages 11 through 18, as well as college freshmen living in dormitories and individuals with special medical conditions, should be vaccinated against this disease. Hepatitis A and B. Approximately 12.5 million Americans have been infected with hepatitis B virus at some point in their lifetime, and about 5,000 people die each year from hepatitis B-related liver disease.

Second, patients shouldn’t over do it! The damage caused of its potential to improve by CIDP to myelin, and the possible damage to axons, results in the body’s ability to recruit fewer muscle fibers to perform strength and endurance, a task. Consequently, those muscle fibers that are engaged are at greater risk of being overworked.

Active Hip Flexion while lying on your side Active exercise ( gravity eliminated): I ndependent movement (Gravity Eliminated) is possible in a gravity “eliminated” position, but not against gravity. For example, a patient may be able to lift their knee toward their chest ( hip flexion) while lying on their side in bed (gravity eliminated position), but not while standing (against gravity). Active exercise ( gravity reduced): M ovement is possible against some gravity, but not against its full pull. To use the same example of hip flexion, a patient may be able to Figure 3.

Active Knee Extension (Gravity Reduced) step. Hip and knee extension also are needed to stand up from a chair, the floor or a squatting position , to jump or to climb stairs. For instance, an individual lift s their foot to the next step via hip flexion, but they progress , or pull , them selves up to the step via hip extension.

The inability to dorsiflex the ankle/foot (F igure 8 ) is a frequent complication of peripheral neuropathies. The condition becomes especially troublesome when the toe drags or catches the floor when walking, causing a patient to stumble or making it impossible to advance the limb for ward without using an assistive device and/or dramati - cally changing the way that they walk. Hip abduction (Figure 6) is most easily visualized as an open -chain exercise .However, the prime muscle of hip abduction, the gluteus medius, performs most of its Figure 8. Active Ankle Dorsiflexion (Against Gravity) work in a weight-bearing mode as a “closed chain ” exer cise when the leg may not even be moving. To expe - rience this phenomenon, place an open hand over your hip; not the boney area at your waist line (that’s part of your pelvis), but the area just below it. Now, if you are able to, lift the opposite leg (while stabilizing yourself against something with your free hand) so that you are standing on one foot. Did you feel anything happen under the hand that is placed over the hip? That’s the gluteus medius contracting. If it didn’t, your body would Upper-extremity exercises . The upper-extremity exercises fall to the side of the leg that is being held up off of the predominantly involve the shoulder, elbow and wrist. floor. Shoulder flexion (Figure 9) is t he chief shoulder action used by individuals to reach for something in front of their body or over their head ( such as shak ing someone’s hand Figure 6. Active Hip Abduction (Against Gravity) or get ting something down from a shelf).

Besides it s use in standing, jumping and climbing, knee extension (Figure 7) also is the motion of kicking — perhaps not something that individuals still do every day, but it was probably more important to people at some time during their lives!
