Commentary: Preliminary Evidence for Training-Induced Changes of Morphology and Phantom Limb Pain
2019
The aim of this study was to investigate whether a special prosthetic training in phantom limb pain patients aimed at increasing the functional use of the prosthesis leads to neural morphological plasticity of brain structures and a reduction in phantom limb pain. For chronic pain disorders, it was shown that morphological alterations due to pain might become at least partially reversed by pain therapies. Phantom limb pain is a chronic pain disorder that is frequently followed by neural plasticity of anatomical brain structures. In our study, 10 patients with amputation of the upper limb participated in a two-week training with a myoelectric prosthesis with somatosensory feedback. Grip stre…
Passive Biomonitoring of Influence of the Communication Traffic on Deposition the Pollution Near the Motorway
2019
W pracy przedstawiono wyniki badań, przeprowadzonych w ramach biomonitoringu pasywnego, polegających na ocenie depozycji metali ciężkich (Ni, Cu, Zn, Cd, Hg i Pb), wzbogacających lokalnie aerozol atmosferyczny w skutek ruchu komunikacyjnego na autostradzie A4 w pobliżu miejscowości Prószków (województwo opolskie). Do badań wykorzystano próbki mchów Pleurozium schreberi, które pobrano w pobliżu autostrady na dystansie 3000 m i w odległości od niej do 120 metrów. Przy wyborze punktów pomiarowych uwzględniono częstotliwość kierunku wiatru na tym terenie. Metale ciężkie oznaczono metodą absorpcyjnej spektometrii atomowej ze wzbudzaniem w płomieniu (F-AAS). Wyniki badań wskazują na to, iż ruch k…
Proprioceptive response strength in the primary sensorimotor cortex is invariant to the range of finger movement
2023
Available online 13 February 2023 Proprioception is the sense of body position and movement that relies on afference from the proprioceptors in muscles and joints. Proprioceptive responses in the primary sensorimotor (SM1) cortex can be elicited by stim- ulating the proprioceptors using evoked (passive) limb movements. In magnetoencephalography (MEG), propri- oceptive processing can be quantified by recording the movement evoked fields (MEFs) and movement-induced beta power modulations or by computing corticokinematic coherence (CKC) between the limb kinematics and cortical activity. We examined whether cortical proprioceptive processing quantified with MEF peak strength, relative beta supp…
Influence of Aerobic Exercise After Static Stretching on Flexibility and Strength in Plantar Flexor Muscles
2020
Aerobic exercise could improve stretch-induced strength deficits. However, mechanisms of the improvement were unclear. The purpose of the study was to examine the effects of aerobic exercise after static stretching (SS) on flexibility and isometric strength in ankle plantar-flexor muscles. Fifteen healthy males received two interventions after SS of their ankle plantar-flexor muscles for 5 min. One was aerobic exercise for 10-min on a cycling ergometer, and the other was a 10-min rest as a control. Range of motion (ROM) of ankle dorsiflexion, passive torque at terminal ROM, muscle-tendon unit (MTU) stiffness, muscle tendon junction displacement, peak torque of ankle plantarflexion, and the …

Misfit evaluation of dental implant-supported metal frameworks manufactured with different techniques: Photoelastic and strain gauge measurements
2016
This study aims to compare in-vitro the fitting accuracy of implant-supported metal frameworks used for full-arch orthodontic restoration. The hypotheses tested were as follows: (1) for a fixed implant morphology, strains developed within the framework depend on how the framework had been fabricated and (2) stresses transferred to the implant–bone interface are related to the amount of framework misfit. Metal frameworks were fabricated using four different manufacturing techniques: conventional lost-wax casting, resin cement luting, electrospark erosion, and computer-aided design/computer-aided manufacturing milling. Each framework was instrumented with three strain gauges to measure strai…
Biological Monitoring Using Lichens as a Source of Information About Contamination of Mountain with Heavy Metals
2022
Abstract The aim of this study was passive biomonitoring of the mountains of southern Poland. Lichens Hypogymnia physodes were used for the study. Concentrations of the heavy metals Ni, Cu, Zn, Cd and Pb were determined in these lichens. The concentrations were measured by atomic absorption spectrometry (AAS). The analysis of the concentrations of the determined heavy metals in the lichen thallus allowed to determine the places with the highest and the lowest contamination with a given heavy metal in the study area. It was shown that the area of Great Czantoria and Big Soszow is the most contaminated with heavy metals among the investigated areas. The study shows that the transport of analy…
