The goal of this study was to investigate surface motor activation zones and their temporal variability using an advanced multi-pad functional electrical stimulation system. With this system motor responses are elicited through concurrent activation of electrode matrix pads collectively termed "virtual electrodes" (VEs) with appropriate stimulation parameters. We observed VEs used to produce selective wrist, finger, and thumb extension movements in 20 therapy sessions of 12 hemiplegic stroke patients. The VEs which produce these three selective movements were created manually on the ergonomic multi-pad electrode by experienced clinicians based on visual inspection of the muscle responses...

BACKGROUND: Manual positive pressure ventilation is an essential skill in a variety of clinical situations. The C&E technique is commonly used with standard facemasks to provide effective ventilation. The Tao mask is a novel design that allows a more ergonomic grip. A seal between the mask and face is made with downward pressure of the palm, centered on the mask, and jaw lift is achieved with 4 fingers centered under the mandible. The purpose of this study was to evaluate the safety and effectiveness of the Tao mask compared to a standard mask before and after the administration of neuromuscular blockade (NMB) using 2 previously established ventilation scales...

Safety and improvement efforts in healthcare education and practice are often limited by inadequate attention to human factors/ergonomics (HFE) principles and methods. Integration of HFE theory and approaches within undergraduate curricula, postgraduate training and healthcare improvement programs will enhance both the performance of care systems (productivity, safety, efficiency, quality) and the well-being (experiences, joy, satisfaction, health and safety) of all the people (patients, staff, visitors) interacting with these systems...

As the clinical advantages of vapor anesthesia (VA) for sedation of patients in ICU become more apparent, the ergonomics, economy and safety issues need to be better addressed. Here we describe the use of a new commercial digital in-line anesthetic vaporizer that can be attached to the inspiratory limb of a ventilator. If used with a simple, and easily assembled secondary circuit and anesthetic reflector, the circuit remains remote from the patient, the VA consumption approaches a physical minimum, VA level is controlled and monitored, and the tidal volume size is not limited...

Digital human modeling tools support proactive ergonomics in optimizing work tasks and workplace layouts. Empirical-statistical model based tools are often used to estimate the force exertion capability of the operators. This work is intended to serve as an initial probing into the usability of a musculoskeletal model based software, AnyBody Modeling Systems (AMS), in evaluating the force exertion capability at different points in the workspace and for various exertion directions. As a first step, it focuses on the modeling approach and the accuracy of one-handed isometric strength estimates of AMS...

This study evaluated the effect of physical, psychosocial and individual factors on the presence of musculoskeletal symptoms (MSS) among surgeons (n = 312) in Iran. Data were collected using questionnaires and analysed by multivariate logistic regression. The prevalence of MSS, particularly in the knees (48.7%), neck (45.8%), low back (42.3%) and shoulders (40.1%) was relatively high. Work-related factors including time spent on surgeries each week (>25 h/week), number of hours working in standing position per day (>4 h/day), moderate to high levels of work-family conflict, duration of each surgery (>3 h), number of years worked as a surgeon (>10 years) and surgical specialty (particularly cardiothoracic and obstetric/gynecologic surgeries) were independently associated with the presence of MSS in different body regions...

Purpose: Many dental hygienists experience musculoskeletal pain during the course of their careers, often as a result of the sustained grips on instruments and repetitive movements employed during clinical practice. Current research suggests that lighter instruments with a larger diameter reduce force and load on the hand during scaling procedures; therefore, the texture and weight of silicone handles is designed to decrease the strain placed on the hand and fingers. The purpose of this research is to investigate and compare the effect of silicone instrument handles and traditional stainless steel instrument handles on hand comfort and strength...

Preventive interventions for reducing occupational risks and health problems among farmers require the identification of factors contributing to unsafe behaviour, but research on this topic is rather limited. A theoretical model for studying factors affecting farmers' use of occupational safety and health (OSH) practices in Iran was developed. The model was empirically tested using data collected from a survey of 301 tomato farmers of Zanjan Province of Iran. The examined OSH practices encompassed a wide range of behaviours, grouped in four categories, i...

BACKGROUND: The operative microscope and endoscope have significantly advanced modern neurosurgery. These devices are nonetheless limited by high costs and suboptimal optics, ergonomics, and maneuverability. A recently developed extracorporeal telescope ("exoscope") operative system combines characteristics from both the operative microscope and endoscope and provides an affordable, portable, high-definition operative experience. Widespread use of exoscopes in neurosurgery has previously been limited by a lack of stereopsis with 2-dimensional(2-D) monitors...

The elbow joint is a complex articulation composed of the humeroulnar and humeroradial joints (for flexion-extension movement) and the proximal radioulnar articulation (for pronation-supination movement). During the flexion-extension movement of the elbow joint, the rotation center changes and this articulation cannot be truly represented as a simple hinge joint. The main goal of this project is to design and assemble a medical rehabilitation exoskeleton for the elbow with one degree of freedom for flexion-extension, using the rotation center for proper patient elbow joint articulation...

BACKGROUND: Robotic camera holders for endoscopic surgery have been available for 20 years but market penetration is low. The current camera holders are controlled by voice, joystick, eyeball tracking, or head movements, and this type of steering has proven to be successful but excessive disturbance of surgical workflow has blocked widespread introduction. The Autolap™ system (MST, Israel) uses a radically different steering concept based on image analysis. This may improve acceptance by smooth, interactive, and fast steering...
