Updated management of occipital nerve stimulator lead migration: case report of a technical challenge
2021
Abstract Electrode migration is a challenge, even with adequate anchoring techniques, due to the high mechanical stress on components of occipital nerve stimulation (ONS) for headache disorders. When a lead displacement of an ONS implant is diagnosed, there are currently different approaches described for its management. Nevertheless current neuromodulation devices are designed like a continuum of components without any intermediate connector, and if a lead displacement is diagnosed, the solution is the complete removal of the electrode from its placement, and its repositioning through an ex-novo procedure. The described technique can allow ONS leads to be revised while minimizing the need …
Trial on the Possibility to Assess the Static and Dynamic Balance in the Elderly with Diseases on the Level of the Supporting Joints
2019
The study aims to identify human walking disorders, proposing a model to solve these disorders, regardless of what caused them. Material and method Clinical and somatometric tests, pedometric investigations and sensors were used. An outpatient trial was conducted for a period of 6 weeks with a frequency of application of the recovery program of 3 times / week. For this study, there were 21 patients over the age of 65 years, which were divided into two groups: the witness group in which 11 patients had upper limb and / or spine disorders, and the control group with 10 patients with degenerative diseases in the knees and ankles. The tests were applied to both groups following the demographic …
Why do antidepressant therapies have such a poor success rate?
2016
Major depression is one of the leading global diseases [1,2]. Treatment is required, because untreated patients suffer not only from impaired emotion [3,4], but also from cognitive [4–6] and somati...
Initial Study on Implementation of the Low-Frequency Wave Markers for the Purpose of Diagnostic Tests’ Performance and Neurofeedback Therapy
2019
Abstract The paper focuses on automation of signal processing, which also considers analysis of biomedical data, such as EEG. The results of the study prove that this enables a better understanding of signal changes and makes it possible to address some specific disturbances. It also makes it possible to describe the relevant changes in signals mathematically and helps to create markers of various brain disorders. This paper presents the study at the initial stage and focuses on the mathematical markers of concentration disorders associated with Theta waves. The presented markers presented are based on Welch’s periodograms. The obtained results are very promising and further studies aimed a…
Innovative Educational Pathways in Spine Surgery: Advanced Virtual Reality–Based Training
2020
Background Over the past few years, a reorganization of the educational pathways has been promoted with the purpose of optimizing the acquisition of competences and their assessment, so as to reduce the risks to both health care professionals and end users. Virtual reality (VR) has been repeatedly tested, initially as a positive reinforcement for more traditional educational pathways and, more recently, as their potential substitute. The aim of this study was to demonstrate the potentiality of VR simulation training in spine surgery. Methods The VR simulator reproduced the lateral lumbar access to the spine. The simulation included a tutorial, the preoperative settings, and the surgical ses…
Breakthrough Cancer Pain: Ten Commandments
2016
The term "breakthrough cancer pain" (BTcP) was introduced about 25 years ago. Peaks of pain intensity reported in patients with cancer had been invariably examined in the past years, providing relevant information for a better knowledge of this phenomenon and its treatment. The aim of this critical review was to provide the golden rules, namely, the 10 commandments, for a correct diagnostic pathway of BTcP and a consequent personalized pharmacological treatment. These are as follows: 1) assessment of background analgesia, 2) drugs used for background analgesia, 3) BTcP is a frequent phenomenon, 4) characteristics of BTcP, 5) diagnosis of BTcP, 6) continuous assessment, 7) tailored pharmacol…
Energy spectral density as valid parameter to compare postural control between subjects with nonspecific chronic low back pain vs healthy subjects : …
2021
Abstract Background Nonspecific chronic low back pain (NSCLBP) is one of the most common and frequent health problems. Objetive to compare postural control (i.e. center of pressure (CoP) displacement and energy spectral density (ESD)) using technological devices (accelerometers and pressure platform) between subjects with NSCLBP and healthy subjects. Methods A cross-sectional case-control study was conducted. Observational study (STROBE). The final sample consisted of 60 subjects (30 NSCLBP subjects and 30 healthy subjects). Triaxial accelerometer and pressure platform were used in order to obtain ESD and CoP displacement measurements during four balance tasks (i.e. with and without vision …
Predictors of individual adaptation to high-volume or high-intensity endurance training in recreational endurance runners
2015
The aim of this study was to investigate factors that can predict individual adaptation to high-volume or high-intensity endurance training. After the first 8-week preparation period, 37 recreational endurance runners were matched into the high-volume training group (HVT) and high-intensity training group (HIT). During the next 8-week training period, HVT increased their running training volume and HIT increased training intensity. Endurance performance characteristics, heart rate variability (HRV), and serum hormone concentrations were measured before and after the training periods. While HIT improved peak treadmill running speed (RSpeak ) 3.1 ± 2.8% (P < 0.001), no significant changes occ…

<p>Translation, validation, and cross-cultural adaptation of the Polish version of the pain sensitivity questionnaire</p>
2019
Introduction The purpose of this study was to provide a translation, cross-cultural adaptation, and validation of the Polish language version of the pain sensitivity questionnaire (PSQ). The process followed widely accepted guidelines. Methods The translated questionnaire underwent thorough psychometric testing. In total, the data of 144 subjects (mean age 52.53±13 years), who underwent evaluation for lower back pain, were included. Results The exploratory factor analysis revealed a two-factor structure, PSQ-moderate and PSQ-minor. The internal consistency was good (Cronbach's α was 0.96). There was a fair and significant correlation between the results of the PSQ and the coping strategy qu…
