“…However, the use of an SLB constrains walking movement. In terms of energy cost, such a constraint functions favorably in stroke patients, but does not in healthy persons 1) . We thus speculated that walking movement with an SLB attached is different from a normal gait pattern.…”

The purpose of the present study was to determine (1) whether the pattern of gait with a short leg brace definitely deviated from that of normal gait, and (2) whether a hybrid mass-spring pendulum model proposed in a systems approach was applicable to walking with a short leg brace. Thirty healthy young adults participated in this study. Step rate and Physiological Cost Index during walking on a treadmill were measured while the participants were wearing (a) short leg brace(s) on one leg or on both legs. Walking velocities were 33.3-100.0 m/min for males and 16.7-83.3 m/min for females. The optimal energy-saving gait when using a short leg brace exhibited deviation from the normal gait pattern, because step length was smaller and the step rate was higher. When the velocity exceeded 90 m/min, however, step length was longer and step rate was lower in short leg brace gait than in normal gait. We thought some modifications to the hybrid model were necessary to explain our results.

Abstract. Children with spastic cerebral palsy (CP) have a strictly individual gait with numerous variations, which is also characterized by increased tonus and hyperreflexion of the muscles. These factors lead to a gait pattern that is inefficient in terms of consumption of energy. The purpose of this study was to clarify the major factor of the deterioration of walking ability on patients with cerebral palsy. Eighteen children (ten boys, eight girls, average age 12.7 years) with CP participated in the study. The children were divided into groups: the independent walking group and the walking aid group (walking with crutches and wheeled walkers); and the diplegia group and the hemiplegia group. The physiological cost index (PCI) for a 3 minute walk at comfortable speed was measured. PCI was compared to the reaction of the cardio-pulmonary system in basic motions (standing up from a table and 10 m walking). Through this test, the whole heart rate and 10 m walking time were measured. PCI and 10 m walking time in the independent walking group and the hemiplegia group were significantly lower than in the walking aid group and the diplegia group, but there was no difference in the endurance index between them. PCI had a significantly positive correlation with the 10 m walking time. However, PCI did not correlate with repetitions and difference in heart rate between before and after standing ups. From these results, it was concluded that the contracture, muscles weakness in the lower limbs, had a strong influence on ambulation level and energy expenditure in spastic CP.
