Video records are an important and relatively cheap tool to assess change in ambulatory ability for children with some ambula- tory ability during development buy discount ginette-35 2mg. The outcome of treating gait problems in children with limited ambula- tory ability is the same as it is for children with more function discount 2 mg ginette-35 visa. These chil- dren should not lose substantial ambulatory ability that they gained. If they do lose ambulatory ability, the cause should be found. Movement Disordered Gait Athetosis Gait problems in individuals with movement disorders can be especially dif- ficult to address. Individuals with athetosis often have spasticity associated with the athetosis, which works as a shock absorber on the pathologic move- ment. Individuals with athetosis may develop significant deformities that make ambulation more difficult, and there is merit in addressing these prob- lems. Therapy to improve athetoid gait is limited but sometimes adding re- sistance through the use of ankle weights or a weighted vest can be helpful. Procedures that will provide stability have the most reliable outcome. For example, correction of planovalgus feet with a fusion is a reliable procedure. There is no benefit of trying muscle balancing or joint preservation treatment in the face of athetosis. Although the post- operative course may be difficult, the outcome of the surgical treatment of fixed knee flexion contractures is usually good. Often, these patients have very high cognitive function and are very hesitant to undertake the correction, even if severe deforming musculoskeletal problems are clearly limiting their activities. Both a full analysis and an experienced surgeon will usually be able to convince them of the benefit if the problem is clear and straightforward.

Artery Vein ◗ Systemic Arteries The systemic arteries begin with the aorta, the largest ar- tery, which measures about 2. This vessel receives blood from the left ventricle then travels downward through the body, branching to all or- gans.
