Despite the diversity of electric wheelchairs, many people with physical limitations and seniors have difficulty using their standard joystick. As a result, they cannot meet their needs or ensure safe travel. Recent assistive technologies can help to give them autonomy and independence. This work deals with the real-time implementation of an artificial intelligence device to overcome these problems. Following a review of the literature from previous work, we present the methodology and process for implementing our intelligent control system on an electric wheelchair...

People who suffer from any kind of motor difficulty face serious complications to autonomously move in their daily lives. However, a growing number research projects which propose different powered wheelchairs control systems are arising. Despite of the interest of the research community in the area, there is no platform that allows an easy integration of various control methods that make use of heterogeneous sensors and computationally demanding algorithms. In this work, an architecture based on virtual organizations of agents is proposed that makes use of a flexible and scalable communication protocol that allows the deployment of embedded agents in computationally limited devices...

A 26-year-old man, who was paraplegic for 6 years due to a motor vehicle accident, presented to the authors' clinic following his incapacity to withstand a sitting posture, the frequent sensation of "clicks" in his back, and a complaint of back pain while in his wheelchair. On imaging, his dorsal spine showed a complete arthrodesis of the primarily fused vertebrae. However, distal to this segment, a Charcot spinal arthropathy with subluxation of T12-L1 was evident. Repair of this complex, uncommon, late complication of his paraplegia by the frequently used fusion techniques was shown to be inappropriate...

The surface roughness of roads is an essential road characteristic. Due to the employed carrying platforms (which are often cars), existing measuring methods can only be used for motorable roads. Until now, there has been no effective method for measuring the surface roughness of un-motorable roads, such as pedestrian and bicycle lanes. This hinders many applications related to pedestrians, cyclists and wheelchair users. In recognizing these research gaps, this paper proposes a method for measuring the surface roughness of pedestrian and bicycle lanes based on Global Positioning System (GPS) and accelerometer sensors on bicycle-mounted smartphones...

Congenital muscular dystrophies are characterised by progressive skeletal muscle weakness from birth or early infancy. Maternal respiratory compromise, joint contractures and presence of spinal instrumentation or fusion are some of the anaesthetic challenges that may be encountered in the obstetric setting. The choice of anaesthetic technique for surgical delivery needs to be considered on an individual basis. Multidisciplinary involvement is paramount to optimise peripartum care and outcomes. In this case report, we present the use of dexmedetomidine, humidified high-flow nasal oxygen, rocuronium and sugammadex in the anaesthetic management of a wheelchair-bound, non-invasive bilevel positive airway pressure ventilation-dependent parturient with congenital muscular dystrophy, who was presenting for caesarean section...

Biomechanics plays an important role helping Paralympic sprinters to excel, having the aerodynamic drag a significant impact on the athlete's performance. The aim of this study was to assess the aerodynamics in different key-moments of the stroke cycle by Computational Fluid Dynamics. A world-ranked wheelchair sprinter was scanned on the racing wheelchair wearing his competition gear and helmet. The sprinter was scanned in three different positions: (i) catch (hands in the 12h position on the hand-rim); (ii) the release (hands in the 18h position on the hand-rim) and; (iii) recovery phase (hands do not touch the hand-rim and are hyperextended backwards)...

Spinal cord injury can cause cognitive impairments even when no cerebral lesion is appreciable. As patients are forced to explore the environment in a non-canonical position (i.e., seated on a wheelchair), a modified relation with space can explain motor-related cognitive differences compared to non-injured individuals. Peripersonal space is encoded in motor terms, that is, in relation to the representation of action abilities and is strictly related to the affordance of reachability. In turn, affordances, the action possibilities suggested by relevant properties of the environment, are related to the perceiver's peripersonal space and motor abilities...
