In a very simplified version discount confido 60caps fast delivery, one now sees that the foot is solidly planted generic 60 caps confido with mastercard, then accepts the weight of mass with as much absorption of shock as pos- sible. The limb then shortens by knee flexion to allow the HAT segment to roll over the top, and in late stance, an energy burst produced by the gas- trocsoleus is put into the system to keep it rolling forward. Weight is again transferred and the leg is shortened to allow it to swing through and be placed for the next cycle. Abnormal Gait Adaptations Pathologic problems can occur in any of the subsystems or mechanical com- ponents of the whole neuromuscular system that is required to make walking possible. When a problem arises in one part of this system, compensations are made in relatively consistent patterns. Usually, these compensations help resolve the deficiency at the heart of the pathology; however, sometimes the compensations can become a source of the pathology as well. The great com- plexity in the system makes finding verifiable reasons for compensations very difficult, and most of the explanations are based only on close observations 304 Cerebral Palsy Management of patients and trying to understand the results of the observed changes. It is even more difficult to try to understand the neuroanatomic anatomy and alterations that give rise to specific patterns of gait. Because there currently is not a good neuroanatomic explanation of how the central program gen- erator works, understanding its response to pathologic insults is even more difficult. Therefore, these pathologic changes will be explained on the basis of dynamic motor control theory, which provides understanding of why pat- terns develop as the system is pulled toward chaotic attractors. For a full description of dynamic motor control, refer to the section on motor control. This method of making predictions based on dynamic motor control theory is similar to techniques used to predict weather patterns. However, in this situation, the impact of growth and development upon a neuromotor system with abnormal control is being predicted. With this theoretical approach, the predictions improve with increased information and the predictions are much better in the short term than long term. Short-term and smaller inter- ventions are easier and more reliable to predict than long-term outcomes and the results of larger interventions. Therefore, the goal is to obtain as much information about each of the neurologic subsystems and the mechanical components as is possible.
The best treatment of this problem is to prevent it from happening by not doing this type of surgery on a functional ambulator order confido 60caps otc. However buy generic confido 60caps, if presented with the problem, working on strengthening the remaining adductor strength and allowing the children to grow often slowly corrects the problems. The wide-based gait may also be due to an abduction contracture, usually of the gluteus medius or fascia latae. The eti- ology of wide-based gait due to a contracture requires identifying the source of the contracture, and the kinematic measure should show increased ab- duction, especially in midstance phase. Once the specific source of the abduction contracture is identified, the treatment is surgical lengthening of the contracted muscle. Fixed contractures of the hip joint may also cause the same effect as muscle contractures. His hip radiographs were spastic hip disease at age 3 years. His gait was characterized by a wide- efficiently with a walker; however, his parents were con- based gait with foot drag and knee stiffness in swing cerned about his wide-based gait and foot drag. Based on these data, Sean had bilateral rectus ical examination, he was not able to get into the walker transfers because the knee stiffness was believed to be without assistance, but had functional gait once he was adding to the tendency to have a wide-based gait. His hip abduction was 50° on each side, initiating a circumduction maneuver because of adductor full hip flexion and extension was present, the popliteal weakness to assist with foot clearance. After the rectus angle was 40°, and he had grade 2 spasticity in the rec- transfers, his base of support narrowed and knee flexion tus, with a positive Ely test at 40°. Transverse Plane Deformity Transverse plane deformity in children is common and is often confused with coronal plane deformity. The difference between scissoring, which is excessive hip adduction, and hip internal rotation gait is often missed. Scis- soring is a completely different motion requiring a different treatment (Fig- ure 7.

Motor Control Motor control is an extremely important aspect of developing good walking skills. Individuals with significant motor control disorders, or the inability to develop motor control, will have significant problems with gait. This aspect is discussed at length in Chapter 4 on neurologic control. Structural Stability The mechanical mobility system includes the muscles, bones, and tendons.
