Compensatory mechanisms in below-knee amputee gait are necessary due to the functional loss of the ankle muscles, especially at higher walking speeds when the mechanical energetic demands of walking are greater. The objective of this study was to examine amputee anterior/posterior (A/P) ground reaction force (GRF) impulses and joint kinetics across a wide range of steady-state walking speeds to...

Gait dysfunction is an early problem identified by patients with Parkinson's disease (PD). Alterations in gait may result in an increase in the energy cost of walking (i.e., walking economy). The purpose of this study was to determine whether walking economy is atypical in patients with PD when compared with healthy controls. A secondary purpose was to evaluate the associations of age, sex, and...

Although dopaminergic medication improves functional mobility in individuals with Parkinson's disease (PD), its effects on walking turns are uncertain. Our goals was to determine whether dopaminergic medication improves preplanned and unplanned walking turns in individuals with PD, compared to healthy controls. Nineteen older adults with mild-to-moderate PD and 17 healthy controls performed one...

introduction: obesity is a complex health problem. the aim of this study was to determine the effects of regular walking with alternate day fasting (adf) on health-related factors of overweight and obese females.‎  methods: 30 healthy inactive, overweight and obese women were divided randomly into three equal groups.  the groups were: control group (bmi: 30.72±4.40 kg/m2); the experimental grou...

One key problem to achieve a dynamically stable walking motion with biped robots is to measure and control the actual state of the robot with respect to its environment. Dynamically stable walking on unstructured terrain and fast walking can only be achieved with an orientation sensor. The control system of the biped robot “Johnnie” is designed such that the orientation of the upper body is con...

To provide a means of identification of human emotion in walking, this paper analyzes the capability of walking activity to reveal a person’s affective states. We obtain pure wrist and ankle accelerometer data, because of redundant information existing in high dimension data, then we set different w(moving average filter window size) and utilize principal component analysis(PCA) to reduce dimen...

The natural history and optimal treatment for idiopathic toe walking are unknown. The literature is full of poorly documented treatment regimens with few even medium term follow up studies. The senior author reports his nearly 30 year approach to this disorder and his failed attempt to perform a follow up study of his particular treatment regimen. We conclude with our considered interpretation ...

background: diabetes is a common disease that can lead to metabolic abnormalities and chronic complications. today, the positive role of physical activity and exercise, especially walking in health human society and has been approved in prevention and control many complications including diabetes. today, the positive role of physical activities and exercise , especially hi wal king in the healt...

BACKGROUND previous studies have reported an association between cognitive function and physical performance, particularly among older adults. OBJECTIVE to examine the association between executive function and performance difference on complex versus usual walking tasks in a sample of non-demented older adults. DESIGN population-based epidemiological study of older people residing in the C...
