Gait disturbances are frequent and disabling in advanced Parkinson's disease. These symptoms respond poorly to usual medical and surgical treatments but were reported to be improved by stimulation of the pedunculopontine nucleus. We studied the effects of stimulating the pedunculopontine nucleus area in six patients with severe freezing of gait, unresponsive to levodopa and subthalamic nucleus ...

Sequel to spinal cord injury (SCI), functional impairment is sustained and the SCI individuals are often confined to wheelchair usage. Current trends of walking rehabilitation adopted is functional electrical stimulation (FES) assisted gait with partial body weight support. However, lack of lower limb proprioception, inability to control complex joint trajectory, rapid energy consumption, unsta...

BACKGROUND Severe gait disturbances and freezing episodes (frequently resistant to optimal dopaminergic treatment) often appear in advanced Parkinson disease (PD). Even several years after initiation, high-frequency subthalamic nucleus deep brain stimulation (STN-DBS) is still very effective for controlling segmental symptoms. However, there are no long-term data on the management of gait disor...

objectives: this study aimed to compare elderly fallers and non fallers by balance test under dual tasks conditions. methods & materials: this study was a analyse-comparative study. subjects were chosen from three parks of tehran. subjects were 20 older adults with no history of falls (aged 72.60±5years) and 21 older adults with a history of 2 or more falls in the last one year (aged 74.50±6 ye...

objectives: this paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. the objective was to control the ankle hysteresis at slow and normal walking speeds. methods: inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for ad...

Optimization of energy cost determines average values of spatio-temporal gait parameters such as step duration, step length or step speed. However, during walking, humans need to adapt these parameters at every step to respond to exogenous and/or endogenic perturbations. While some neurological mechanisms that trigger these responses are known, our understanding of the fundamental principles go...

Objectives: There exists no study concerning gait pattern while engaging in dual-task activities on different sizes of mobile devices. The present study aimed to compare gait patterns during normal walking, walking with smartphone use, and walking with tablet use.  Methods: Seventeen healthy female participants with an age range of 19-24 years (mean±SD age: 20.29±1.61 years, weight: 49.82±4.46...

Objectives: The purpose of this study was to evaluate the concurrent validity of the Farsi version of Functional Gait Assessment (FGA), Timed Up & Go (TUG), and Gait Speed tests in Persian communitydwelling older adults. Methods: Subjects were 100 males in falling or no falling history group (50 subjects in each group). Subjects were community-dwelling adults aged 60-90 years who were living...

Background. There have been many studies on partial weight support walking training. However, most studies have been performed in treadmill settings, not in actual walking environments. Objectives. This study aimed to investigate the effect of partial weight support ground walking training on the temporal and spatial gait parameters of chronic stroke patients. Methods. This study was designed...

In the present scenario like COVID-19 pandemic, to maintain physical distance, gait-based biometric is a must. Human gait identification very difficult process, but it suitable distance that also gives good results at low resolution conditions even with face features are not clear. This study describes construction of smart carpet measures ground response force (GRF) and spatio-temporal paramet...
