Excercise test

BACKGROUND: Impaired selective motor control, weakness and spasticity represent the key characteristics of motor disability in the context of bilateral spastic cerebral palsy. Independent walking ability is an important goal and training of the gluteal muscles can improve endurance and gait stability. Combining conventional physical excercises with a neuromodulatory, non-invasive technique like repetitive neuromuscular magnetic stimulation probably enhances effects of the treatment. This prospective study aimed to assess the clinical effects of repetitive neuromuscular magnetic stimulation in combination with a personalized functional physical training offered to children and adolescents with bilateral spastic cerebral palsy...

OBJECTIVE: The aim of this pilot study was to assess physical fitness and its relationship with functional dyspnea in survivors of COVID-19 6 months after their discharge from the hospital. METHODS: Data collected routinely from people referred for cardiopulmonary exercise testing (CPET) following hospitalization for COVID-19 were retrospectively analyzed. Persistent dyspnea was assessed using the modified Medical Research Council dyspnea scale. RESULTS: Twenty-three people with persistent symptoms were referred for CPET...

Because medical professionals lack the means to monitor exercises performed by patients in their home environment directly, there is a strong case for introducing technological solutions into this domain. They include methods that use wireless inertial sensors, which emit signals recorded and processed by special applications that work with mobile devices. This paper's aim is (a) to evaluate whether such sensors are suitable for qualitative and quantitative motion analysis, and (b) to determine the repeatability of results over a few recordings...

Non-synostotic plagiocephaly consists in an asymmetry of the skull due to mechanical forces applied in utero or postnatally: main differential diagnosis is with true synostotic asymmetry, which is caused by the premature closure of a suture. The correction of positional forms is mostly conservative, with 3 main strategies: counterpositioning, physiotherapy and helmet therapy. There is no synthesized evidence on which is the most effective. The Authors evaluate the modification of antropometric measurments before and after a pediatric physical therapy program in a sample of patients with non-synostotic skull asymmetry, in order to evaluate the improvements in the skull shape...

BACKGROUND: Osteoporosis is a systemic skeletal disease that causes weakening of the bones which increases the risk of fractures. Especially hip fractures lead to substantial physical, psychological, social and economic burden both for the patients and the governments. Exercises and physically active life style are essential preventive and therapeutic approaches for osteoporosis. Kinesiophobia is an irrational fear of movement due to the belief of susceptibility to injury. It is associated with lower levels of physical activity...

OBJECTIVES: Prognosis of patients with anomalous origin of the left coronary artery from pulmonary artery has dramatically improved as a result of both, early diagnosis and improvements in surgical techniques. Post surgical complications are rare and most patients show quick improvement of the left ventricular performance after repair with complete functional recovery within one year after surgery. Exercise-induced electrocardiographic changes have been found in patients postoperatively and scars and perfusion deficits of the left ventricle may not be detected by standard echocardiographic evaluation...

Chronic airflow limitation, caused by chronic obstructive pulmonary disease (COPD) or by asthma, is believed to change the shape and the position of the diaphragm due to an increase in lung volume. We have made a comparison of magnetic resonance imaging (MRI) of diaphragm in supine position with pulmonary functions, respiratory muscle function and exercise tolerance. We have studied the differences between patients with COPD, patients with asthma, and healthy subjects. Most interestingly we found the lung hyperinflation leads to the changes in diaphragmatic excursions during the breathing cycle, seen in the differences between the maximal expiratory diaphragm position (DPex) in patients with COPD and control group (p=0...

Lotus seedpod proanthocyanidins (LSPC) as a kind of polyphenols is widely used in medicines, cosmetics, health products. High-intensity exercise can cause damage to the body's organs and tissues. Different doses of LSPC is given to mice to check the function of protect effect to the body's organs and tissues under high-intensity exercise. The hemoglobin (HB) content, red blood cell (RBC) number and white blood cell (WBC) number were tested for mice after exercise. The activity of superoxide dismutase (SOD) and the contents of glutathione (GSH) and malondialdehyde (MDA) in muscle and viscera were evaluated...

Primary lymphedema can be managed effectively as a form of chronic lymphedema by a sequenced and targeted treatment and management program based around a combination of Decongestive Lymphatic Therapy (DLT) with compression therapy, when the latter is desired as an adjunct to DLT. Treatment in the maintenance phase should include compression garments, self-management, including self-massage, meticulous personal hygiene and skin care, in addition to lymphtransport-promoting excercises and activities, and, if desired, pneumatic compression therapy applied in the home...

BACKGROUND: Excercise self-efficacy is believed to influence physical activity bahavior. PURPOSE: The purpose of this study is to assess the psychometric aspects of the Exercise Self-efficacy Scale (ESS) in a type 2 diabetes Dutch Primary care sample. METHOD: Type 2 diabetes patients (n = 322; <80 years old) filled in the ESS and the short questionnaire to assess health enhancing physical activity (SQUASH). The structural validity of the ESS was assessed by means of principal axis factor analyses and confirmatory factor analysis...

Interleukin-6 (IL-6) plays a central role in the pathogenesis of multiple myeloma, acting both as a growth and a survival factor for myeloma cells. IL-6 has been recently shown to possess three topologically distinct receptor binding sites: site 1 for binding to the subunit specific chain IL-6R alpha and sites 2 and 3 for the interaction with two separate subunits of the signalling chain gp130. We have generated a set of IL-6 receptor antagonists carrying substitutions that abolish interaction with gp130 at either site 2 alone (site 2 antagonist) or at both sites 2 and 3 (site 2+3 antagonist)...

BACKGROUND: Myasthenia gravis (MG) is a disease with autoimmune background. Impaired neuromuscular transmission is caused by blockage of acetylcholine receptors on postsynaptic membrane by circulating specific antibodies. Recognition of myasthenia gravis in children, especially its ocular type, may be difficult due to occurrence of similar clinical symptoms in other diseases like ecephalomyopathies. MG is characterized by variety of clinical symptoms and their alternations during excercise and rest...

Primary lymphedema can be managed safely as one of the chronic lymphedemas by a proper combination of DLT with compression therapy. Treatment in the maintenance phase should include compression garments, self management including the compression therapy, self massage and meticulous personal hygiene and skin care in addition to lymph-transport promoting excercises. The management of primary lymphedema can be further improved with proper addition of surgical therapy either reconstructive or ablative. These two surgical therapies can be effective only when fully integrated with MLD-based DLT postoperatively...

Mitochondrial DNA (mtDNA) mutations accumulate in the skeletal muscle of patients with mtDNA disease, and also as part of healthy ageing. Simulations of human muscle fibres suggest that, over many decades, the continuous destruction and copying of mtDNA (relaxed replication) can lead to dramatic changes in the percentage level of mutant mtDNA in non-dividing cells through random genetic drift. This process should apply to both pathogenic and neutral mutations. To test this hypothesis we sequenced the entire mitochondrial genome for 20 muscle fibres from a healthy elderly 85-year-old individual, chosen because of the low frequency of cytochrome c oxidase negative fibres...

Few muscle disorders can be diagnosed by repetitive nerve stimulation (RNS). Decreasing compound muscle action potentials (CMAP) on high frequency RNS is recorded in muscle channelopathies, and particularly in sporadic and recessive congenital myotonia. In this myopathy, decreasing CMAP after exercise test and RNS are the most sensitive electrophysiological in detecting muscle membrane dysfunction and are considered highly informative even in mildly symptomatic patients. We report on a patient with excercise-induced diffuse muscle cramps and myalgia; muscle biopsy and laboratory investigations were normal...

Non-genomic effects of aldosterone on oxidative metabolism of skeletal muscle have been shown, recently. To further characterize these rapid effects on the increase of phosphocreatine (PCr) in the recovery period after isometric exercise, a randomized cross-over placebo-controlled study was conducted on 9 healthy volunteers. Hypoxia was chosen to test the dependence of the effect on oxygen supply and thus its relation to oxidative vs non-oxidative metabolism. Parameters related to the energy metabolism of calf muscles were measured by 31P magnetic resonance spectroscopy during four repetitive contractions in four different tests (hypoxia [FiO2=0...

The purpose of this study was to evaluate the efficacy of a community-based exercise course applied to a group of American Indians (AI) who, because of physician recommendation and/or self-motivation, desired to increase their physical activity. Changes in physiological measurements and self-perceived measurements were determined following a moderate-intensity exercise program implemented through a randomized controlled trial to a population of American Indian elders between the ages of 55 and 75 living in an urban area...

UNLABELLED: Aging increases certain thrombotic risk factors, such as fibrinogen, factor VII, PAI-1 and plasma viscosity, contributing to cardiovascular diseases being the principal cause of death in developed countries. Physical exercise can counteract this tendency by influencing such factors. PURPOSE: To assess the effect of regular physical exercise on fibrinogen, factor VII, PAI-1 and plasma viscosity in an elderly group. METHODS: Sixty-three old people of both sexes, aged between 65 and 94, participated in this study, and were randomly distributed between a test group (n = 31) and a control group (n = 32)...
