INTRODUCTION:: No effective countermeasure for space-induced bone loss has yet been identified. It has been hypothesized that an effective exercise regimen would elicit loads on the lower extremity which resemble those encountered on Earth. Although a treadmill has been used on shuttle flights, the loads to which the lower extremity ...

The functional electrical stimulation (FES) assisted gait of paraplegic patients is inferior to that of healthy subjects. The difference can be observed in terms of speed, upright balance, biomechanical energy consumption, and generation of propulsion forces in the direction of walking. The biomechanical structure of paraplegic subjects is the same ...

We hypothesized that short-term endurance training improves balance in older adults, if training involves movements that "stress" balance. We tested the hypothesis by looking for a dose-response relationship between movement during exercise and balance improvement. The study was a single-blinded, randomized controlled trial. Subjects were sedentary adults (N = 106) ...

We investigated the coordination between breathing and walking in humans to elucidate whether the coordination degree depends more on metabolic load or on breathing or stride frequencies and whether coordination causes energetic economization expressed by reduction of oxygen uptake (VO2). Eighteen healthy volunteers walked on a treadmill at three load ...

This study sought to test the hypothesis that injections of botulinum toxin type A (BTX-A) at the mid belly of the gastrocnemius muscle in spastic hemiplegic adults produce superior clinical results to proximal injections directed toward the muscular origin. We designed a randomized, double-blind, placebo-controlled intervention study at a university ...

Activity controlled pacemakers are the most widely used rate adaptive systems. We studied second-generation activity controlled systems (accelerometer) in 21 patients with such an accelerometer controlled system implanted during walking level and stairs. We compared them to the rate of vibration controlled, first-generation activity pacemakers and to the sinus rate ...

BACKGROUND: Epidemiologic evidence suggests that 8,368 kJ or 2000 kcal per week of moderate physical activity, including walking and stair climbing, can reduce risk of coronary heart disease (CHD). The goal of this study was to assess the effects of this amount of these two activities on physical fitness and ...

Many people develop skin symptoms after long-distance walks, but little is known about the aetiology of these. In this study we took 11 biopsies from 10 long-distance walkers who walked 80 km. All biopsies originated from purpuric lesions on the lower legs, which had appeared during walking. In all 11 ...

At similar levels of carbon dioxide production (VCO2) and oxygen consumption (VO2), runners have been shown to have a greater minute ventilation (VE) during running as compared to walking. The mechanism responsible for these differences has yet to be identified. To determine if these differences are a result of differences ...

We have reviewed 28 tibial lengthenings in 14 patients with achondroplasia at an average age of 15 years, and compared the effectiveness of physiotherapy and an orthosis in preventing an equinus deformity. Physiotherapy of 15 min a day was ineffective even when the patients were able to walk. An orthosis ...
Beillot J - - 1996
The energy cost of walking using a reciprocating gait orthosis (RGOII) with functional electrical stimulation (FES) was assessed in 14 patients with spastic complete paraplegia from six rehabilitation centres. Before and after training asing RGOII with FES, the subjects performed a progressive maximal test on an arm-crank ergometer to obtain ...
Feigin L - - 1996
The prediction of mobility soon after a stroke should allow proper selection for rehabilitation and suggest the long-term prognosis of gait ability. Stable gait is related to midline body orientation and equilibrium mechanisms. We proposed that the sitting balance during the 1st, 2nd, or 3rd weeks after a hemiplegia could ...
Dietz V - - 1995
Adaptation in leg muscle activity and coordination between lower limbs were studied during walking on a treadmill with split belts in one group of parkinsonian patients and one of age-matched healthy subjects. Four different belt speeds (0.25/0.5/0.75/1.0 m/sec) were applied in selected combinations to the left and right leg. While ...

Previous studies have shown a reduction in intraocular pressure (IOP) from many forms of exertion, ranging from walking to exhausting exercise. The variability in these results may be due to several factors, such as age, diurnal and seasonal variations, drinking water or coffee before the test, acute hyperglycaemia, and physical ...

Previous research has yielded an inconclusive picture of the effects of music and scent on walking. Few laboratory studies have detected a beneficial effect of music; olfactory research has shown performance is positively affected for repetitive tasks but not yet on walking. The influence of these two types of stimuli ...
