Usage of BODE index to estimate the results of rehabilitation of patients with chronic obstructive lung disease

2008

Abstract: BODE index is the prognostic indicator in chronic obstructive lung disease, in which beyond bronchial obstruction the body mass index, dyspnea and competence exercise are taken into consideration. The indicator consists of few elements: B – BMI, O – obturation, D – dyspnea, E – exercise, taking into consideration various constitutional aspects of disease. The purpose of the paper was usage of BODE index in estimation of results of rehabilitation of patients with Chronic Obstructive Lung Disease. 60 in- hospital patients with chronic obstructive lung disease were examined, in Specialized Hospital MSWiA (Ministry of Interior and Administration) in Glucholazy. The pa-tients, who were…

Positional transversal release is effective as stretching on range of movement, performance and balance: a cross-over study.

2022

Abstract Background The aim of this study was to compare the positional transversal release (PTR) technique to stretching and evaluate the acute effects on range of movement (ROM), performance and balance. Methods Thirty-two healthy individuals (25.3 ± 5.6 years; 68.8 ± 12.5 kg; 172.0 ± 8.8 cm) were tested on four occasions 1 week apart. ROM through a passive straight leg raise, jumping performance through a standing long jump (SLJ) and balance through the Y-balance test were measured. Each measure was assessed before (T0), immediately after (T1) and after 15 min (T2) of the provided intervention. On the first occasion, no intervention was administered (CG). The intervention order was rando…

Comparison of posturographic parameters between young taekwondo and tennis athletes

2018

[Purpose] Physical activity can influence the development of postural control and balance. Therefore, the aim of study was to use posturography assessment to compare balance control on the Romberg test between athletes in two very different sports, taekwondo and tennis. [Participants and Methods] Twenty-nine young athletes participated in the study, 11 forming the taekwondo group and 18 the tennis group. Posturography was performed using the FreeMed system (Sensor Medica). Between-group differences were evaluated using unpaired Student’s t-test. [Results] There was a significance between-group difference in the centre of pressure and the ellipse surface area with no between-group difference…

Improvement of balance in a 7-year-old child through a six-week learning programme

2018

Given that human beings are constantly subjected to equilibration processes, developing basic perceptual motor skills, especially balance, is important. The main purpose of this study is the validation of the tasks and the progression of activities that form the learning programme for balance development in a six-week didactic unit of 12 sessions (2 sessions per week), for 6 to 9 year old children (1st, 2nd, and 3rd grade of elementary school in Brazil). The changes in balance after applying the programme are also analysed through a new measuring protocol using baropodometry. Although the session was put into practice in a class of 28 children, data were extracted from a 7-year-old child. T…

Factors affecting peak impact force during soccer headers and implications for the mitigation of head injuries

2020

It has been documented that up to 22% of all soccer injuries are concussions. This is in part due to players purposely using their head to direct the ball during play. To provide a more complete understanding of head trauma in soccer athletes, this study characterized the effects of four soccer ball characteristics (size, inflation pressure, mass, velocity) on the resulting peak impact force as it relates to the potential for incurring neurophysiological changes. A total of six hundred trials were performed on size 4 and 5 soccer balls as well as a novel lightweight soccer ball. Impact force was measured with a force plate and ball velocity was determined using motion capture. These data we…

Crenobalneotherapy (spa therapy) in patients with knee and generalized osteoarthritis: a post-hoc subgroup analysis of a large multicentre randomized…

2014

Abstract Objective To determine whether the addition of spa therapy to home exercises provides any benefit over exercises and the usual treatment alone in the management of generalised osteoarthritis associated with knee osteoarthritis. Methods This study was a post-hoc subgroup analysis of our randomised multicentre trial ( www.clinicaltrial.gov : NCT00348777 ). Participants who met the inclusion criteria of generalized osteoarthritis (Kellgren, American College of Rheumatology, or Dougados criteria) were extracted from the original randomised controlled trial. They had been randomised using Zelen randomisation. The treatment group received 18 days of spa treatment in addition to a home ex…

E-sports kā profesija

2019

20. gs. beigās un 21. gs. sākuma straujā tehnoloģiju attīstība radīja vidi elektroniskā sporta (e-sporta) izveidei. E-sports ir videospēļu spēļu spēlēšana profesionālā līmenī, kas apvieno dažādu žanru videospēles. E-sportam ir izveidojusies vērā ņemama fanu kultūra, kura skaita ziņa spēj konkurēt ar tradicionāliem sporta veidiem, un spēj piepildīt lielākās tradicionālā sporta arēnas. 2018. gadā tika izveidota Baltijas e-sporta līga. Baltijas e-sporta līgā e-sportisti no Latvijas, Lietuvas un Igaunijas var individuāli vai ar komandu piedalīties dažādās pamatdisciplīnās kā Counter-Strike, PUBG, Rocket League, League of Legends ar nodrošinātu balvas fondu. Ņemot vērā, ka Latvijā līdz šim netie…

Improving accuracy of FIR filters for computing convolution transforms for smooth non-bandlimited signals

2019

We propose to improve the accuracy of FIR filters for computing convolution transforms for smooth non-bandlimited (NBL) signals by designing filters by the identification method with using a pair of bandlimited portions of the chosen NBL input and output signals related with each other by the given transform. A design example of type IV linear phase differentiator is presented, where filter coefficients are calculated from the bandlimited portions of the Cauchy pulse and its derivative. The performance of the designed differentiator is evaluated by comparing the accuracy of computed derivatives for several smooth NBL test signals, such as the Cauchy pulse, the Hilbert transform of Cauchy pu…

Numerical modelling of the tensile behaviour of BFRCM strips

2019

This paper aims at investigating the tensile behaviour of basalt fibres on cementitious matrix for the strengthening of masonry structures. The use of Basalt Fibre Reinforced Cementitious Matrix (BFRCM) is favourably considered by the scientific community because it represents a natural composite material with high compatibility with stone and masonry substrate. The study is developed through the generation of Finite Element (FE) models capable of reproducing the tensile behaviour of BFRCM strips with different number of layers of grid. For the scope, the micro-modelling approach is adopted assuming different levels of detail for the simulation of the interface constitutive behaviour. Fibre…
