[Ti] Título:The Vienna psychosocial assessment procedure for bionic reconstruction in patients with global brachial plexus injuries.

[Ab] Resumo:BACKGROUND: Global brachial plexopathies cause major sensory and motor deficits in the affected arm and hand. Many patients report of psychosocial consequences including chronic pain, decreased self-sufficiency, and poor body image. Bionic reconstruction, which includes the amputation and prosthetic replacement of the functionless limb, has been shown to restore hand function in patients where classic reconstructions have failed. Patient selection and psychological evaluation before such a life-changing procedure are crucial for optimal functional outcomes. In this paper we describe a psychosocial assessment procedure for bionic reconstruction in patients with complete brachial plexopathies and present psychosocial outcome variables associated with bionic reconstruction. METHODS: Between 2013 and 2017 psychosocial assessments were performed in eight patients with global brachial plexopathies. We conducted semi-structured interviews exploring the psychosocial adjustment related to the accident, the overall psychosocial status, as well as motivational aspects related to an anticipated amputation and expectations of functional prosthetic outcome. During the interview patients were asked to respond freely. Their answers were transcribed verbatim by the interviewer and analyzed afterwards on the basis of a pre-defined item scoring system. The interview was augmented by quantitative evaluation of self-reported mental health and social functioning (SF-36 Health Survey), body image (FKB-20) and deafferentation pain (VAS). Additionally, psychosocial outcome variables were presented for seven patients before and after bionic reconstruction. RESULTS: Qualitative data revealed several psychological stressors with long-term negative effects on patients with complete brachial plexopathies. 88% of patients felt functionally limited to a great extent due to their disability, and all of them reported constant, debilitating pain in the deafferented hand. After bionic reconstruction the physical component summary scale increased from 30.80 ± 5.31 to 37.37 ± 8.41 (p-value = 0.028), the mental component summary scale improved from 43.19 ± 8.32 to 54.76 ± 6.78 (p-value = 0.018). VAS scores indicative of deafferentation pain improved from 7.8 to 5.6 after prosthetic hand replacement (p-value = 0.018). Negative body evaluation improved from 60.71 ± 12.12 to 53.29 ± 11.03 (p-value = 0.075). Vital body dynamics increased from 38.57 ± 13.44 to 44.43 ± 16.15 (p-value = 0.109). CONCLUSIONS: Bionic reconstruction provides hope for patients with complete brachial plexopathies who have lived without hand function for years or even decades. Critical patient selection is crucial and the psychosocial assessment procedure including a semi-structured interview helps identify unresolved psychological issues, which could preclude or delay bionic reconstruction. Bionic reconstruction improves overall quality of life, restores an intact self-image and reduces deafferentation pain.

[Ti] Título:The pattern and degree of capsular fibrous sheaths surrounding cochlear electrode arrays.

[Ab] Resumo:An inflammatory tissue reaction around the electrode array of a cochlear implant (CI) is common, in particular at the electrode insertion region (cochleostomy) where mechanical trauma often occurs. However, the factors determining the amount and causes of fibrous reaction surrounding the stimulating electrode, especially medially near the perimodiolar location, are unclear. Temporal bone (TB) specimens from patients who had undergone cochlear implantation during life with either Advanced Bionics (AB) Clarion ™ or HiRes90K™ (Sylmar, CA, USA) devices that have a half-band and a pre-curved electrode, or Cochlear ™ Nucleus (Sydney, Australia) device that have a full-band and a straight electrode were evaluated. The thickness of the fibrous tissue surrounding the electrode array of both types of CI devices at both the lower (LB) and upper (UB) basal turns of the cochlea was quantified at three locations: the medial, inferior, and superior aspects of the sheath. Fracture of the osseous spiral lamina and/or marked displacement of the basilar membrane were interpreted as evidence of intracochlear trauma. In addition, post-operative word recognition scores, duration of implantation, and post-operative programming data were evaluated. Seven TBs from six patients implanted with AB devices and five TBs from five patients implanted with Nucleus devices were included. A fibrous capsule around the stimulating electrode array was present in all twelve specimens. TBs implanted with AB device had a significantly thicker fibrous capsule at the medial aspect than at the inferior or superior aspects at both locations (LB and UB) of the cochlea (Wilcoxon signed-ranks test, p < 0.01). TBs implanted with a Nucleus device had no difference in the thickness of the fibrous capsule surrounding the track of the electrode array (Wilcoxon signed-ranks test, p > 0.05). Nine of fourteen (64%) basal turns of the cochlea (LB and UB of seven TBs) implanted with AB devices demonstrated intracochlear trauma compared to two of ten (20%) basal turns of the cochlea (LB and UB of five TBs) with Nucleus devices, (Fisher exact test, p < 0.05). There was no significant correlation between the thickness of the fibrous tissue and the duration of implantation or the word recognition scores (Spearman rho, p = 0.06, p = 0.4 respectively). Our outcomes demonstrated the development of a robust fibrous tissue sheath medially closest to the site of electric stimulation in cases implanted with the AB device electrode, but not in cases implanted with the Nucleus device. The cause of the asymmetric fibrous sheath may be multifactorial including insertional trauma, a foreign body response, and/or asymmetric current flow.

[Ab] Resumo:Detecting the threats of the external obstacles to the power lines can ensure the stability of the power system. Inspired by the attention mechanism and binocular vision of human visual system, an intelligent power line inspection system is presented in this paper. Human visual attention mechanism in this intelligent inspection system is used to detect and track power lines in image sequences according to the shape information of power lines, and the binocular visual model is used to calculate the 3D coordinate information of obstacles and power lines. In order to improve the real time and accuracy of the system, we propose a new matching strategy based on the traditional SURF algorithm. The experimental results show that the system is able to accurately locate the position of the obstacles around power lines automatically, and the designed power line inspection system is effective in complex backgrounds, and there are no missing detection instances under different conditions.

[Ab] Resumo:A complete mechanical design concept of an electromyogram (EMG) controlled hybrid prosthetic hand, with 24 degree of freedom (DOF) anthropomorphic structure is presented. Brushless DC motors along with Shape Memory Alloy (SMA) actuators are used to achieve dexterous functionality. An 8 channel EMG is used for detecting 7 basic hand gestures for control purposes. The prosthetic hand will be integrated with the Neural Network (NNE) based controller in the next phase of the study.

[Ab] Resumo:Biobotic research involving neurostimulation of instrumented insects to control their locomotion is finding potential as an alternative solution towards development of centimeter-scale distributed swarm robotics. To improve the reliability of biobotic agents, their control mechanism needs to be precisely characterized. To achieve this goal, this paper presents our initial efforts for statistical assessment of the angular response of roach biobots to the applied bioelectrical stimulus. Subsequent findings can help to understand the effect of each stimulation parameter individually or collectively and eventually reach reliable and consistent biobotic control suitable for real life scenarios.
