WORK ACTIVITIES AT INCREASED RISK OF TRAUMATIC INJURIES: AN INTEGRATED PREVENTIVE APPROACH

2022

Included in the scope of workplace safety is that relating to potential accidents, i.e. the harmful consequences for human health crossed with the work environment factor. In the study of the determinism of these accidental events, it is important to achieve a biomechanical balance between two main elements: the human and the work environment (consisting of the physical, chemical and environmental factors, i.e. the equipment and what generates its use). Considering the most recent statistically recorded incidents, our analysis has focused on the accident sphere proper, where an imbalance in the above-mentioned binomial triggers the activation of multiple disciplines that actively and pro-ac…

Validation of the use of Actigraph GT3X accelerometers to estimate energy expenditure in full time manual wheelchair users with spinal cord injury.

2013

Study design: Cross-sectional validation study. Objectives: The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body. Setting: Non-hospitalized paraplegics’ community. Methods: Twenty participants (age=40.03 years, weight=75.8 kg and height=1.76 m) completed sedentary, propulsion and housework activities for 10 min each. A portable gas analyzer was used to record VO2. Additionally, four accelerometers (placed on the non-dominant chest, non-dominant waist and both wrists) were used to collect second-by-second a…

Central dislocation of the jaw-joint into the middle cranial fossa

1981

Summary The authors' case of central dislocation of the jaw-joint is used to discuss the incidence, mechanism of causation and the problems of clinical diagnosis, and the possible lines of treatment are listed. The management of the central dislocation in our case consisted of surgical reduction of the articular process by means of traction with hooked retractors over a fulcrum in the molar region.

The eSports conundrum: Is the sports sciences community ready to face them? A perspective

2020

The reality of eSports is something much more complex than individual users playing video games. There are several characteristics that eSports have in common with traditional sports: from the spirit of competition to the structural composition of the teams, including the increase in performance with training and practice, up to the injuries and physical and psychological stress of the athlete. The number of scientific papers interested in this reality is still relatively low, although in recent years there has been a significant increase in this regard. Probably the lack of knowledge of the world of eSports by inexperts can represent an initial obstacle in the approach to this environment.…

EMG amplitude of the biceps femoris during jumping compared to landing movements.

2013

Abstract Hamstrings injury is a common occurrence in athletic performance. These injuries tend to occur during a deceleration or landing task suggesting the negative work may be a key component in hamstrings injury. The purpose of this study was to investigate the muscular activity (EMG) of the biceps femoris (BF) in different phases (concentric vs. eccentric) of a Counter Movement Jump (CMJ), Squat Jump (SJ) and the Braking Phase (BP) of a landing task. Twelve female volleyball players performed 5 CMJs, SJs and BPs while surface EMG was recorded using a MuscleLab (BoscoSystemTM, Norway). EMG values were normalized to an maximal voluntary contraction. A repeated measures analysis of varianc…

Update on mechanism and therapeutic implications of spinal cord stimulation and cerebral hemodynamics: A narrative review

2017

Spinal cord stimulation (SCS) is well known for its early role in the management of chronic pain, mainly failed back surgery syndrome (FBSS), spasticity, and bowel and bladder dysfunction. In more recent years, SCS has been proposed for patients suffering from refractory angina or peripheral vasculopathies in order to gain symptom relief, thus indicating some hemodynamic effect on the peripheral circulation. Taking into account this scientific observation, since the late1980s, researchers have started to investigate the potential effect of SCS on cerebral blood flow (CBF) regulation and its possible application in certain pathological settings dealing with vascular pattern dysfunction, such…

Deep learning approach for prediction of impact peak appearance at ground reaction force signal of running activity

2020

Protruding impact peak is one of the features of vertical ground reaction force (GRF) that is related to injury risk while running. The present research is dedicated to predicting GRF impact peak appearance by setting a binary classification problem. Kinematic data, namely a number of raw signals in the sagittal plane, collected by the Vicon motion capture system (Oxford Metrics Group, UK) were employed as predictors. Therefore, the input data for the predictive model are presented as a multi-channel time series. Deep learning techniques, namely five convolutional neural network (CNN) models were applied to the binary classification analysis, based on a Multi-Layer Perceptron (MLP) classifi…

Comparison of endoscopic and open resection for Haglund tuberosity in a cadaver study.

2006

Background: About half of patients who have Haglund disease may require treatment by surgical resection of the superior portion of the calcaneal tuberosity. Endoscopic techniques have been described as alternatives to open surgery, but only results of uncontrolled retrospective clinical investigations have been reported. Up to now no research is available which compares these different procedures. Methods: A controlled laboratory study was done to evaluate the morphologic appearance of the superior portion of the calcaneal tuberosity after endoscopic or open resection. The tuberosity was resected in 15 isolated fresh-frozen human cadaver lower limb specimens with either open (nine) or endos…

Results of isolated posterolateral corner reconstruction

2010

Abstract Background Isolated posterolateral corner (PLC) tears are relatively rare events. Various surgical techniques to treat posterolateral knee instability have been described; because surgical results are linked to cruciate reconstructions it has been difficult to date to define whether one surgical procedure has better prognosis than another. The goal of this study is to determine the clinical outcome of PLC reconstruction following fibular-based technique. Materials and methods We retrospectively evaluated a case series of patients who received isolated PLC reconstruction between March 2005 and January 2007. Ten patients were surgically treated for isolated injuries and were availabl…
