Motion management

Andrea Mike, T László Tamás
Dizziness is one of the most common causes of medical visits. Management of the dizzy patient may be challenging both for the general practitioner, in emergency departments, and special clinics, as behind a seemingly homogeneous clinical presentation several very different etiologies may occur. Research of the last two century enriched our knowledge about physiology and pathophysiology of the vestibular system. Much knowledge is now available about the labyrinth being able to sense head motions and gravity, processing of afferent vestibular stimuli, reflectory oculomotor and postural control, or recovery of the vestibular system...

BACKGROUND: Proximal humeral fractures are common and a major concern in public health resources utilization. There is an increase in the use of reverse total shoulder arthroplasty (RTSA) as an option for complex fractures in the elderly. The complexity of the technique in RTSA is increased because of the fracture. To find an advantage of locking stems in RTSA for the treatment of proximal humeral fractures, we designed a comparative study between fracture-dedicated locking stems vs. cemented stems...

Congenital knee dislocation (CDK) is a rare condition, and its treatment is subject to debate. Here, we report on a new treatment for CDK (using a hexapod-type external fixator, HEF) in a three-year-old child with Larsen syndrome and grade III anterior dislocations of both knees. The left knee was treated with serial splints, whereas an HEF was used to treat an irreducible dislocation of the right knee. Two HEF aluminium rings were applied surgically. The procedure involved a distraction of the knee, then tibial posterior translation, and lastly progressive flexion...

In this paper, we consider a Gross-Pitaevskii (GP) equation with a time-dependent nonlinearity and a spatiotemporal complex linear term which describes the dynamics of matter-wave solitons in Bose-Einstein condensates (BECs) with time-dependent interatomic interactions in a parabolic potential in the presence of feeding or loss of atoms. We establish the integrability conditions under which analytical solutions describing the modulational instability and the propagation of both bright and dark solitary waves on a continuous wave background are obtained...

Hypertrophic cardiomyopathy (HC) has historically been characterized as a disease of substantial left ventricular hypertrophy, often associated with dynamic left ventricular outflow tract obstruction. However, we have recently encountered patients with subaortic obstruction and only minimal basal septal thickness, raising important management implications. Thereby, we sought to characterize the natural history and treatment strategies for this under-recognized subgroup of HC patients with dynamic obstruction...

BACKGROUND: Dementia affects cognitive functioning, physical functioning, activities of daily living (ADLs), and quality of life (QOL). Pharmacological treatments to manage, cure or prevent dementia remain controversial. Therefore development of non-pharmacological approaches to prevent, or at least delay the onset and progression of dementia is urgently needed. Passive exercise is proposed to be such a non-pharmacological alternative. This study primarily aims to investigate the effects of three different forms of passive exercise on QOL and ADLs of institutionalized patients with dementia...

Image-guided radiotherapy takes place at every step of the treatment in lung cancer, from treatment planning, with fusion imaging, to daily in-room repositioning. Managing tumoral and surrounding thoracic structures motion has been allowed since the routine use of 4D computed tomography (4DCT). The integration of respiratory motion has been made with "passive" techniques based on reconstruction images from 4DCT planning, or "active" techniques adapted to the patient's breathing. Daily repositioning is based on regular images, weekly or daily, low (kV) or high (MV) energy...

PURPOSE: Currently, there is no consensus on the optimal treatment for scaphoid nonunion with avascular necrosis (AVN). Various techniques, often involving vascularized corticocancellous bone grafting, have been proposed. The authors hypothesized that similar outcomes might be possible with volar plate fixation augmented with autogenous pure cancellous graft. METHODS: The authors performed a retrospective chart review of 13 cases of scaphoid nonunions with AVN in 12 patients treated with plate fixation and pure cancellous bone grafting...

BACKGROUND: Synovial sarcoma is a rare soft tissue sarcoma which most commonly affects the extremities of young adults. Axilla involvement by this sarcoma is very rare especially with involvement of the brachial plexus. This combination adds to the challenge in approaching such tumors which might significantly affect survival and function. CASE PRESENTATION: Herein, we present a 48-year-old female patient who presented with an isolated painless lump in her right axilla...

BACKGROUND: Drywall installation has an injury rate four times that of the construction industry average. Workers are exposed to hazards related to slips, falls, and falling objects, in addition to the large and awkward loads they must carry. Drywall sheets can weigh more than 100 lb. and contribute to disabling musculoskeletal injuries of the shoulders and back. OBJECTIVE: In this study, an unpowered lift assist device was developed to manage the load of a drywall sheet during the installation process...

A comprehensive knowledge of the thoracic shape and kinematics is essential for effective risk prevention, diagnose and proper management of thoracic disorders and assessment of treatment or rehabilitation strategies as well as for in silico and in vitro models for realistic applications of boundary conditions. After an extensive search of the existing literature, this study summarizes 45 studies on in vivo thoracic kyphosis and kinematics and creates a systematic and detailed database. The thoracic kyphosis over T1-12 determined using non-radiological devices (34°) was relatively less than measured using radiological devices (40°) during standing...

BACKGROUND: Electrotherapeutic modalities have proven to be one of the best therapeutic options for myofascial pain syndrome, targeting the myofascial trigger points (MTrPs). Combined therapy (CT) is described with paucity in literature as the application of ultrasound (US) and electrical stimulating current concurrently and at the same site. AIM: The aim was to compare between low-frequency, high-intensity burst transcutaneous electrical nerve stimulation CT (burst-TENS-CT) and medium-frequency, low-intensity amplitude modulated frequency CT (AMF-CT) on upper trapezius active MTrPs (A-MTrPs)...

Vehicle counting from an unmanned aerial vehicle (UAV) is becoming a popular research topic in traffic monitoring. Camera mounted on UAV can be regarded as a visual sensor for collecting aerial videos. Compared with traditional sensors, the UAV can be flexibly deployed to the areas that need to be monitored and can provide a larger perspective. In this paper, a novel framework for vehicle counting based on aerial videos is proposed. In our framework, the moving-object detector can handle the following two situations: static background and moving background...
