Abstract:
Abstract Purpose Degenerative cervical myelopathy (DCM) is the most common non-traumatic cause of spinal cord dysfunction. Prediction of the neurological outcome after surgery is important. The aim of this study was to analyze the relationship between first symptoms of DCM and the neurological outcome after surgery. Methods A retrospective analysis over a period of 10 years was performed. First symptoms such as cervicobrachial neuralgia, sensory and motor deficits and gait disturbances were evaluated regarding the postoperative neurological outcome. The modified Japanese Orthopedic Association Score (mJOA Score) was used to evaluate neurological outcome. Results In total, 411 patients (263 males, 64%) with a median age of 62.6 ± 12.1 years were included. Cervicobrachial neuralgia was described in 40.2%, gait disturbance in 31.6%, sensory deficits in 19% and motor deficits in 9.2% as first symptom. Patients with cervicobrachial neuralgia were significantly younger (median age of 58 years, p = 0.0005) than patients with gait disturbances (median age of 68 years, p = 0.0005). Patients with gait disturbances and motor deficits as first symptom showed significantly lower mJOA Scores than other patients (p = 0.0005). Additionally, motor deficits and gait disturbance were negative predictors for postoperative outcome according to the mJOA Score. Conclusion Motor deficits and gait disturbances as the first symptom of DCM are negative predictors for postoperative neurological outcome. Nevertheless, patients with motor deficits and gait disturbance significantly profit from the surgical treatment despite poor preoperative mJOA Score.

Abstract:
ABSTRACK Introduction:Diabetic peripheral neuropathy causes sensory disturbances such as the reduced sensation of vibration, pressure, pain, and joint position, this will result in reduced ability to balance and coordinate a person's gait. Sensory-motor exercise is used to correct muscle imbalances through sensory input. This study aims to determine the effect of exercise therapy on sensory improvement, balance, and functional ability using the sensory-motor exercise method in patients with diabetic peripheral neuropathy. The research method used in this study is an experiment with the case report method, and the sample is taken using an incidental technique. Results: After being given exercise therapy using the sensory-motor exercise method, the results were an increase in sensory input sensitivity, an increase in static balance, an increase in dynamic balance, and an increase in the patient's functional ability in the form of a better walking pattern. Conclusion: exercise therapy using the sensory-motor exercise method effectively improves balance and improves walking patterns in patients with diabetic peripheral neuropathy. Suggestion: exercise to increase the movement ability of sensory and functional functions can be combined with sensory training in patients with diabetic peripheral neuropathy.

Abstract:
Investigation of the brain pathology in experimental ischemia requires adequate methods for assessing the neurological deficit that occurs in laboratory animals, including sensory-based and behavioural disorders. In this research, we aimed to compare motor and behavioural disorders in rats with partial and subtotal experimental cerebral ischemia. The rats modelled with cerebral ischemia are found to exhibit a decrease in muscle strength, resistance to hypoxia, motor and emotional activity. The animals with incomplete cerebral ischemia demonstrated more pronounced sensory-based motor and behavioural disorders compared both with those modelled with partial cerebral ischemia and, in particular, with the control group.

Abstract:
The selection of electric machines for an Electric Vehicle (EV) is mainly based on reliability, efficiency, and robustness, which makes the 5-phase Permanent Magnet Synchronous Motor (PMSM) among the best candidates. However, control performance of any motor drive can be deeply affected by both: (1) internal disturbances caused by parametric variations and model uncertainties and (2) external disturbances related to sensor faults or unexpected speed or torque variation. To ensure stability under those conditions, an Active Disturbance Rejection Controller (ADRC) based on an online dynamic compensation of estimated internal and external disturbances, and a Linear ADRC (LADRC) are investigated in this paper. The control performance was compared with traditional controller and evaluated by considering parametric variation, unmodeled disturbances, and speed sensor fault. The achieved results clearly highlight the effectiveness and high control performance of the proposed ADRC-based strategies.

Abstract:
Abstract Objective Multiple sclerosis (MS) is an autoimmune demyelinating disease more common in women than men, usually diagnosed between 20-30 years of age. Approximately 50% of individuals with MS develop cognitive dysfunction, with men and progressive MS subtype cases at higher risk (Beatty & Aupperle, 2002). Mr. Doe’s case is unique because he was diagnosed with primary progressive MS at age 56 and demonstrated only mild cognitive dysfunction. Method Mr. Doe presented to his neurologist with complaints of extreme fatigue, slowed processing, and sensory and motor disturbances. He was seen for neuropsychological evaluation one year after diagnosis and was reassessed one year later. He reported worsening mood including passive suicidal ideation since diagnosis. He reported difficulties with work duties (attorney) and household demands due to gradual motor and sensory disturbances, slowed processing speed, fatigue, and mood disturbance. Results Mr. Doe’s initial neuropsychological assessment revealed variability in auditory working memory, weakness in sustained visual attention, and mild deficits in upper extremity fine motor dexterity. Memory, executive functioning, language, and processing speed were all intact unless a motor component was involved (mild decline after one year). His cognitive performances remained generally stable after one year, but depression, anxiety, and hopelessness levels were all significantly worse. Conclusions Although Mr. Doe’s impairments are extremely mild and somewhat unexpected given the primary progressive MS diagnosis, his gender, and age, the affected domains are consistent with the diagnosis. This case demonstrates the importance of understanding base rates for conditions we assess, but also not ruling out lower base rate conditions.

Abstract:
Charcot-Marie-Tooth (CMT) or Hereditary Motor and Sensory Neuropathy (HMSN) is the most common hereditary peripheral nerve disease with progressive chronic weakness, muscle atrophy, and sensory disturbances. There are several types and subtypes of CMT with their respective clinical manifestations. In this article, we reported a patient with of CMT type X. A 43-year-old male patient was referred to a neurology clinic with weakness in both limbs for 2 years, accompanied by tingling and sensory disturbance in both hands and feet. There are several of his family members who had similar complaints. Lumbosacral magnetic resonance imaging (MRI) examination revealed mild nucleus pulposus herniation. Electroneuromyography (ENMG) examination revealed demyelinating sensory motor polyneuropathy. Histopathological examination of nerve biopsy showed demyelination of the sural nerve. It is hard to make a diagnosis of CMT, because it requires high suspicion from clinicians once encounter a suspected case and also need to supported by sophisticated equipment such as electrophysiological examinations, nerve biopsy examinations, and genetic examinations. It is vital for clinicians for being able to diagnose CMT correctly and provide treatment as soon as possible in order to maintain the patients’ quality of life.

Abstract:
Although a vast literature attests to the belief that psychosocial disturbance is an important component of functional gastrointestinal disorders (FGID), the relation of life stress, psychological distress and personality to the development of these disorders is poorly understood. The broad objective of this thesis is to provide data on relations between psychosocial factors and FGID, especially irritable bowel syndrome (IBS) and functional dyspepsia (FD), in representative outpatient samples. Issues not previously addressed are examined in a series of studies. The first two studies are concerned with relations between psychosocial factors, extraintestinal (somatic) symptoms and the number and type of FGID syndromes present at consultation and, in IBS patients, the prospective relation of psychosocial factors to changes in symptom intensity over 16 months. The last three studies relate psychosocial factors to gastrointestinal (GI) transit, motor, and sensory function in FGID, abnormalities in these parameters representing the putative origin of symptoms in FGID. In total, 350 patients participated, representing a 95% participation rate. Important features of the methodology include the use of a recently standardised symptom-based classification system for FGID, an objective and reliable interview-based life stress instrument (The Life Events and Difficulties Schedule), and sophisticated and sensitive technologies to assess GI transit, motor and sensory function. Novel measures, which conceptually take into account the chronic, fluctuating and recurrent course of IBS and FD syndromes, and the tendency of these syndromes to coexist, are also included. Thus, measures of symptom outcome assess the number of syndromes present, while the symptom intensity variable reflects the severity and frequency of both FD and IBS symptoms, if both are present. Similarly, with respect to altered transit, and motor and sensory function, physiological outcome variables reflect not only the presence of an abnormality but the number of regions affected, and the type and number of abnormalities present. Cross-sectional findings showed for the first time that psychosocial disturbance is associated with FGID symptomatology in a quantitative manner, that chronic life stress threat is central to this process and this stress-related process is a prominent feature of a particular group of syndromes (ie IBS/FD) defined primarily by the presence of pain and discomfort. A combination of psychological, social and biological factors combined to predict the number of FGID syndromes present at entry into the study. Prominent among them was an angry, reactive and anxious (neurotic) personality, chronic life stress threat, increased coping, poor emotional support and increased age. In addition to a greater number of FD/IBS syndromes, individuals with an anger-reactive response style had experienced more intense pain and discomfort, and displayed more complete sensorimotor disturbance. Longitudinal data demonstrated (also for the first time) the strength, consistency and unequivocal direction of the relation of chronic threat to symptom intensity over time. Almost all of the within subject variance in symptom intensity levels (assessed on 3 occasions over a 16 month period) was explained by the severity of chronic threat during the previous 6 months or more. For 76% of IBS patients, the presence vs the absence of one or more highly threatening chronic stressors predicted with considerable precision, the long-term clinical outcome. Thus, no patient exposed to even one such stressor improved clinically (ie by at least 50%) over the follow-up period, while in contrast, all patients who improved clinically did so in the absence of such a stressor. For 24% of patients, however, failure to improve clinically could not be explained by any psychological, social (including life stress) or demographic factor included in this study. Key risk indicators of a poor outcome at 16 months were identified - chronic life stress threat, the severity of baseline GI symptomatology, and female gender. Life stress is important because it alone determined the magnitude and direction of change in symptom intensity over time, while the severity of baseline GI symptomatology revealed the extent of improvement required to achieve a recovery, and female gender predicted the presence of a larger number of FD/IBS syndromes in women long-term. Widespread hypomotility, which was almost exclusive to women in this study, represents one factor that may inhibit improvement (or rate of improvement) for women over time. Finally, these findings have identified a psychophysiological subgroup, with underlying psychosocial, motor (and perhaps also sensory) dysfunctions that are more specific for women than men, and which does not seem to be distinctive of any particular FGID subgroup.

Abstract:
The human motor system exhibits remarkable adaptability, enabling us to maintain high levels of performance despite ever-changing requirements. There are many potential sources of error duringmovement to which the motor system may need to adapt: the properties of our bodies or tools may vary over time, either at a dynamic or a kinematic level; our senses may become miscalibrated over time and mislead us as to the state of our bodies or the true location of an intended goal; the relationship between sensory stimuli and movement goals may change. Despite these many varied ways in which our movements may be disturbed, existing models of human motor adaptation have tended to assume just a single adaptive component. In this thesis, I argue that the motor system maintains multiple components of adaptation, corresponding to the multiple potential sources of error to which we are exposed. I outline some of the shortcomings of existing adaptation models in scenarious where multiple kinds of disturbances may be present - in particular examining how different distal learning problems associated with different classes of disturbance can affect adaptation within alternative cerebellar-based learning architectures - and outline the computational challenges associated with extending these existing models. Focusing on the specific problem in which the potential disturbances are miscalibrations of vision and proprioception and changes in arm dynamics during reaching, a unified model of sensory and motor adaptation is derived based on the principle of Bayesian estimation of the disturbances given noisy observations. This model is able to account parsimoniously for previously reported patterns of sensory and motor adaptation during exposure to shifted visual feedback. However the model additionally makes the novel and surprising prediction that adaptation to a force field will also result in sensory adaptation. These predictions are confirmed experimentally. The success of the model strongly supports the idea that the motor system maintains multiple components of adaptation, which it updates according to the principles of Bayesian estimation.

Abstract:

A recent trend in evolutionary robotics and artificial life research is to maximize self-organization in the design of robotic systems, in particular using artificial evolutionary techniques, in order to reduce the human designer bias. This dissertation presents experiments in competitive co-evolutionary robotics that integrate and extend previous work on competitive co-evolution of neural robot controllers in a predator-prey scenario with work on the ‘co-evolution’ of robot morphology and control systems. The focus here is on a systematic investigation of tradeoffs and interdependencies between morphological parameters and behavioral strategies through a series of predator-prey experiments in which increasingly many aspects are subject to self-organization through competitive co-evolution. The results show that there is a strong interdependency between morphological parameters and behavioral strategies evolved, and that the competitive co-evolutionary process was able to find a balance between and within these two aspects. It is therefore concluded that competitive co-evolution has great potential as a method for the automatic design of robotic systems.

Abstract:
The neural connections between the vestibular, visual, proprioceptive and voluntary inputs are essential for the control of neck posture and movements. One mechanism how this is achieved is by vestibulo-spinal reflexes, such as vestibulo-collic reflex (VCR), and cervico-collic reflexes (CCR). The main role of these reflexes is to stabilize the head either in space or relative to the trunk, respectively. The VCR stabilises the head in space while the CCR tends to re-align the head on the trunk. These two reflexes can work synergistically or an-tagonistically according to context and movement goals. The aim of this thesis is to investigate the sensory-motor control of the sternocleidomastoid muscle and the nature of the functional interactions between the vestibular system and neck muscles in healthy participants and in patients with bilateral vestibular loss. Specifically, the experiments performed were designed to a) investigate how head control is organised in healthy subjects and b) to examine how this functional interaction is modulated in patients with vestibular dysfunction. Firstly, a novel head-restraint paradigm is used in order to attempt to isolate a neck stretch reflex in the SCM muscle. Using this paradigm, the activation of the vestibular system is minimised. This permits differentiation between vestibular and neck muscles reflexes. Forehead skull taps and tendon taps were used to differentiate between vestibular-mediated response and stretch responses and vestibularless patients were also included to aid with assessing the contribution of stretch reflexes to head control. Secondly, the sensory-motor organization of the induced responses by tendon tap was investigated following vestibular caloric stimulation to see if it was modulated by vestibular input. Finally, in order to assess cortical aspects of neck control the cortico-spinal excitability of the sternomastoid muscle have been assessed, with non-invasive brain stimulation (transcranial magnetic stimulation), and visual stimulation (rotating disc) in healthy participants. To be able to better understand visual processing of the latter (motion visual stimuli).In the final part of the thesis the effects of visual motion stimulation on the excitability of the visual cortex, both in areas V1 and V5 were investigated. Applying tendon taps of the left sterno-mastoid (SM) relatively long latencies (32msec) EMG responses have been recorded from the ipsilateral and contralateral SCM muscles in con-tracted and relaxed conditions in both healthy and bilateral vestibular failure subjects (BVF). These latencies (32ms) indicating a long loop, possibly via the cortex or subcortical struc-tures would suggest a long loop reflex. These long loop responses are not modulated applying caloric vestibular stimulation and suggest that although the vestibular system is activated, the neural pathway between the vestibular system and the motor cortex is not activated by the tap since this is purely a spinal reflex. In addition the physiological mechanisms of head neck control are significantly influenced by the visual cues. Visual-vestibular and proprioceptive loops are probably involved in head-neck sensory motor control.

Abstract:
Over the last decades, robotic devices for neurorehabilitation have been developed with the aim of providing better and faster improvement of motor performance. These devices are being used to help patients repeat movements and (re)learn different dynamic tasks. Over the years, these devices have become bigger and more complex, so as to provide the end user with a more realistic and sophisticated stimuli while still allowing the experimenter to have control over the interaction forces that can potentially shape the motor behaviour. However, experimental results have shown no clear advantage of these complex devices over simpler versions. In this context, this thesis investigates sensory-motor processes of human interaction, which can help us understand the main issues for rehabilitation devices and how to overcome the limitations of simple devices to train particular motor behaviours. Conventional neurorehabilitation of motor function relies on haptic interaction between the patient and physiotherapist. However, how humans deal with human-human interactions is largely unknown, and has been little studied. In this regard, experiments of the first section of the thesis investigate the mechanisms of interaction during human-human collaborative tasks. It goes from identifying the different strategies that dyads can take to proposing methods to measure and understand redundancy and synchrony in haptic interactions. It also shows that one can shape the interaction between partners by modifying only the visual information provided to each agent. Learning a novel skill requires integration of different sensory modalities, in particular vision and proprioception. Hence, one can expect that learning will depend on the mechanical characteristics of the device. For instance, a device with limited degrees of freedom will reduce the amount of information about the environment, modify the dynamics of the task and prevent certain error-based corrections. To investigate this, the second section of the thesis examines whether the lack of proprioceptive feedback that is created due to mechanical constraints or haptic guidance can be substituted with visual information. Psychophysical experiments with healthy subjects and some preliminary experiments with stroke patients presented in this thesis support the idea that by incorporating task-relevant visual feedback into simple devices, one could deliver effective neurorehabilitation protocols. The contributions of the thesis are not limited to the role of visual feedback to shape motor behaviour, but also advance our understanding on the mechanisms of learning and human-human interaction.

Abstract:
Injury and neurodegenerative conditions of the spinal cord can lead to paralysis and loss of sensation. Cell therapeutic approaches can restore sensory innervation of the spinal cord following injury and protect spinal cord cells from degeneration. This thesis primarily focuses on the restoration of deaffarented sensory fibres following injury to the dorsal root and spinal cord. These injuries lead to the formation of a non-permissive glial scar that prevents sensory axons from reinnervating spinal cord targets. It takes advantage of a dorsal root injury model that closely mimics spinal root avulsion injuries occurring in humans. In the first part of the thesis, three different neural progenitor types from human or murine sources are tested for their regenerative properties following their transplantation to the site of dorsal root avulsion injury. In the second part, the ability of murine neural progenitors to protect spinal motor neurons from a neurodegenerative process is tested. In the first original research article, I show that human embryonic stem cell derived neural progenitors are able to restore sensorimotor functions, mediated by the formation of a tissue bridge that allows ingrowth of sensory axons into the spinal cord. In the second research article, I present that murine boundary cap neural crest stem cells, a special type of neural progenitor that governs the entry of sensory axons into the spinal cord during development, are unable to form a permissive tissue bridge. This is possibly caused by the contribution of transplant derived ingrowth non-permissive glial cells. In the third research article, I show that human neural progenitors derived from foetal sources are capable of stimulating sensory ingrowth and that they ameliorate the glial scar. When this approach is combined with the delivery of sensory outgrowth stimulating neurotrophic factors, these cells fail to form a permissive tissue bridge and fail to modify the glial scar. In the final research article, murine boundary cap neural crest stem cells are shown to protect motor neurons, which harbor an amyotrophic lateral sclerosis causing mutation, from oxidative stress. Oxidative stress is a pathological component of amyotrophic lateral sclerosis in human patients. Taken together, this thesis provides first evidence that sensory regeneration following a spinal root avulsion injury can be achieved by transplantation of human neural progenitors. In addition, it introduces murine boundary cap neural crest stem cells as interesting candidates for the cell therapeutic treatment of amyotrophic lateral sclerosis.

Abstract:
AbstractWith aging, a combination of gravitational forces, laxity of the skin due to loss of elasticity, decreased dermal thickness and loss of dermal appendages results in ptotic, hanging skin. Face lift or rhytidectomy as its name suggest is a procedure to partially eliminate folds, creases and wrinkles (rhytids) caused by gravity and degeneration. The creation of two large cervicofacial flaps which after suspension and trimming, produces an overall tightening the skin and the fascial envelope of the face and neck results in restored anatomical structure. Treatment of the SMAS layer is important and can be broadly categorized into 3 methods. They are plication, elevation and imbrication and SMASectomy. Platysma elevation and plication can be carried out simultaneously for the neck. Face lift can help to negate some of these gravitational problems and produce some intrinsic improvement. Complications include haematoma, skin ischaemia and necrosis, obvious scarring, sensory disturbances, motor nerve disturbances and ear lobe irregularities.

Abstract:
When a system controlled by a low-frequency digital feedback controller experiences a sudden large disturbance such as an impact, its dynamic performance and stability may deteriorate. Inspired by various reflex actions in human body, analog reflex actions are designed to compensate the effects of large disturbances to digital controllers. The human reflexes are triggered by motor neurons as soon as sensory neurons detect stimuli above a threshold without any decision process involving the brain. In this approach, large disturbances are attenuated more rapidly by external sensor-actuator modules connected with only analog components. A series of simulations is performed to design the reflex actions and its findings are articulated in this paper. The system performance is evaluated by measuring the peak error and the settling time. The paper presents a discussion on various techniques to determine appropriate reflex actions with only minimal information about the disturbance profiles.

Full text
Abstract:
This paper presents control of a Halbach linear motor for nano-precision positioning. Using an FPGA based decoding scheme and sensor signal processing, a 0.23nm root-mean-square (RMS) sensor noise level has been obtained from a 4 micrometer period sinusoidal quadrature encoder. Disturbances to the linear motor are studied at nanometer scale. When the motor is supported by the air bearing without feedback control, the mechanical motion measured by the sensor shows substantial low frequency oscillation around 10Hz. Under a PID digital servo feedback control, the stage can be brought to a regulated state of 11.14nm RMS error at 10kHz sampling rate, otherwise not achieved by lower sampling rate. Although PID servo loop substantially reduces the 10Hz motion, a 60Hz vibration and its harmonics begin to dominate at nanometer level. It is suspected and confirmed by experiments to be due to the coupling of the DC power supply/amplifier and control computer to the AC power source. A robust repetitive control scheme is employed to reject the 60Hz disturbance and its harmonics and bring the regulated state to 1.78nm RMS value.

Abstract:
This paper develops a camera gimbal platform for stabilization and tracking purposes. The main focus of this research is analytical modeling of an inertially stabilized platform with the prediction of the angular stability. The mechanical model of the platform includes, moment of inertia, motor drive, and performance of the gyro to measure the disturbances of the platform. The gimbal/motor system is developed and simulated and feedback control scheme is designed to stabilize and maintain the line of sight (LOS) for tracking purposes. The model integrates a PI2 controller using a PID-I approach for the system stability. The effect of vibration induced disturbance in the system is investigated to simulate the realistic behavior of an inertially stabilized platform. The simulation results of the four types of commercial gyros are presented to calculate the required values for stability purposes. The results from the simulation generated the performance limits chart describing the working condition of the low cost sensors vs the high cost sensors. As the vibration level increased, the performance of the highest quality sensor greatly decreased. This verifies the value and necessity of modeling and simulating to understand the component trade studies to ensure correct sensor selection for the desired application.

Full text
Abstract:
This paper presents a project developed at the University of Alabama at Birmingham (UAB) aimed to design, implement, and test an off-road Unmanned Ground Vehicle (UGV) with individually controlled four drive wheels that operate in stochastic terrain conditions. An all-wheel drive off-road UGV equipped with individual electric dc motors for each wheel offers tremendous potential to control the torque delivered to each individual wheel in order to maximize UGV slip efficiency by minimizing slip power losses. As previous studies showed, this can be achieved by maintaining all drive wheels slippages the same. Utilizing this approach, an analytical method to control angular velocities of all wheels was developed to provide the same slippages of the four wheels. This model-based method was implemented in an inverse dynamics-based control algorithm of the UGV to overcome stochastic terrain conditions and minimize wheel slip power losses and maintain a given velocity profile. In this paper, mechanical and electrical components and control algorithm of the UGV are described in order to achieve the objective. Optical encoders built-in each dc motor are used to measure the actual angular velocity of each wheel. A fifth wheel rotary encoder sensor is attached to the chassis to measure the distance travel and estimate the longitudinal velocity of the UGV. In addition, the UGV is equipped with four electric current sensors to measure the current draw from each dc motor at various load conditions. Four motor drivers are used to control the dc motors using National Instruments single-board RIO controller. Moreover, power system diagrams and controller pinout connections are presented in detail and thus explain how all these components are integrated in a mechatronic system. The inverse dynamics control algorithm is implemented in real-time to control each dc motors individually. The integrated mechatronics system is distinguished by its robustness to stochastic external disturbances as shown in the previous papers. It also shows a promising adaptability to disturbances in wheel load torques and changes in stochastic terrain properties. The proposed approach, modeling and hardware implementation opens up a new way to the optimization and control of both unmanned ground vehicle dynamics and vehicle energy efficiency by optimizing and controlling individual power distribution to the drive wheels.

Full text
Abstract:
Adaptive-passive devices such as adaptive Helmholtz Resonators (HR) and tunable vibration absorbers have been shown to be suitable for controlling both narrowband disturbances and lightly damped structural/acoustic modes driven by broadband disturbances. In order to track changes in the disturbance or changes in the modes, the natural frequency of the absorber, ωn, is tuned to match the observed signals. This is achieved by altering some physical parameter of the control device such as the stiffness of a vibration absorber or the neck cross-sectional area of a Helmholtz resonator. In order to automatically adjust these devices, control systems and tuning algorithms have been developed, most of which involve a digital controller. However, this paper looks specifically at the development of a simple analog controller used to drive a DC motor in order to tune a mechanical device. A two sensor dot product method is employed where one sensor is placed inside of the control device, such as a Helmholtz Resonator, and the other on/in the system under control, such as in a room. The outputs from the two sensors are multiplied together and subsequently low passed in order to extract a low frequency “DC” voltage which acts as an error signal. The error signal is related to the relative phase of the two sensor signals and determines the direction in which the device should be tuned. When the two signals are 90° apart, the system is tuned (i.e. the inner product produces zero DC level). If the drive frequency ω is different than the tuned frequency, then the system is mis-tuned. The relationship between the mis-tuning, ωn-ω, and the error is not linear, but for small perturbations a linear approximation can be used to investigate the stability and performance of the system. The gradient of the function is shown to be largest when the mis-tuning error is zero and is inversely proportional to the damping level in the control device. Once stability of the system has been ensured the ability of the system to track changes in drive frequency is investigated experimentally. The control system is demonstrated using an adaptive Helmholtz resonator which has a variable cross-sectional neck via an iris diaphragm. The iris is controlled using a small DC motor; two microphones (one mounted internally and one externally) are used to supply the driving signal to the circuit.

Abstract:
Background: Since Space Tourism is closer to reality, a review of the most prevalent neurological pathologies in microgravity is needed. Objective: Review major neurological afflictions in astronauts. Methods: Research into bibliographic reviews at PubMed, using the descriptors “astronauts” and “neurological disorders” Results: Several neurological alterations, such as ataxy, intracranial hypertension (ICH), neuromuscular disorders, ocular disturbances and changes in cognitive functions were assigned to a microgravity environment. Astronauts returning from space presented ICH; being the main pathophysiology hypothesis referred to a change in the liquor dynamics as a result of venous drainage obstruction and hematoencephalic barrier. Also, gravity doesn’t act on the neurovestibular system during space flights. This phenomenon can lead to Space Motion Sickness, situation in which astronauts report balance, coordination and sight disturbances, as well as movement illusions. A subset of this syndrome, called Space Movement Disorder, may occur; which includes symptoms, such as flushing, anorexia, nausea, vomiting, dizziness and malaise. Based on electromagnetic resonance, the occurrence of problems with movement time, balance, spatial working memory and motor coordination after the return of the space crew suggests alterations in cerebellum’s function and structure, which is responsible for the coordination and the fine motor control. Conclusion: Most studies presented disruptions of the neurofunctional homeostasis, for instance, changes in functional connectivity while in rest and alterations of the white and grey matter in sensor motor, somatosensory and cognitive regions of the brain.

Abstract:
Background: X-linked Adrenoleukodystrophy (X-ALD) represents a key inherited metabolic disorder in neurological practice, representing an important differential diagnosis in different neurological contexts. Symptomatic female patients have been scarcely studied in large cohorts. Objectives: Evaluation of clinical, laboratory and genetic findings from a Brazilian cohort of women with X-ALD. Methods, design and setting: We performed a retrospective observational study of clinical, biochemical, genetic, neuroimaging and neurophysiological aspects of 10 Brazilian female patients with X-linked Adrenoleukodystrophy under clinical follow-up at the Neurometabolic Unit, Division of Neuromuscular Diseases, Federal University of São Paulo (UNIFESP), São Paulo, Brazil. Results: Mean age at diagnosis was 46.2 years and at symptom-onset was 39 years. Female patients presented with spastic paraparesis and neurogenic bladder (60%), cognitive decline (50%), demyelinating sensorimotor polyneuropathy (40%), cerebellar ataxia (30%), epilepsy (20%), apraxia and psychotic symptoms (10%). The most common misdiagnosis were Primary Progressive Multiple Sclerosis and Hereditary Spastic Paraplegia. The main neuroimaging findings were corticospinal tract hyperintensity and cervical and thoracic spinal cord atrophy (60%), unspecific white matter changes (40%) and typical parieto-occipital leukodystrophy. All patients had abnormal profiles of plasma very-long chain fatty acids, all with elevated C26 levels and 80% with elevated C24 levels, but all with abnormally raised C26:C22 and C26:C24 ratio. The most common pathogenic variant observed was c.311G>A (p.Arg104His) (60%). Conclusions: Female patients with ABCD1 pathogenic variants must be carefully evaluated for neuropsychiatric disturbances and followed-up until elderly due to the common occurrence of variable motor, autonomic and sensory compromise.

Full text
Abstract:
A practical magnetic-bearing control system has been designed based upon modeling and simulation of the dynamics of a jet engine turbine shaft and bearing system. Simulations include models for flexible rotor dynamics, magnetic actuators, auxiliary touchdown bearings, ordinary and extraordinary external loads, and disturbances from rotor imbalance, stator vibration, and noise. The shaft model includes a motor-generator which acts as an uncontrolled negative stiffness. The control system is decentralized, running independently for each of the five physical axes of control (1 axial, 4 radial). The fundamental algorithm is classical PID: proportional for broadband stiffness, integrator (with anti-windup) for high load-carrying capacity, and derivative to dampen disturbances. Additional phase lead is provided via a first-order pole-zero pair. The vibration due to rotor imbalance is eliminated by an autobalancing algorithm. Compensation for magnetic actuator non-linearity and varying rotor-stator gap is provided by feedback of sensed magnetic flux, using sensor coils built into the actuator. The control design can be readily implemented using a commercial Digital Signal Processing system. The magnetic bearing actuators will be driven with commercial power amplifiers via customized front-end electronics. Based upon simulations, the design goal has been achieved of keeping the shaft within two mils of its desired location at the magnetic bearings, under all normal loads. Under extreme external loads, the capacity of the magnetic bearings will be exceeded and touchdown will occur upon backup mechanical bearings. Simulation shows that the control design handles this critical event, which determines the force slew rate required from the actuators.

Review question / Objective: To summarise measures or aspects targeted at reducing the incidence of adverse events during the delivery of exercise interventions through telerehabilitation in patients after stroke. Background: The sequelae in people with stroke are diverse. Regarding physical function post-stroke, functional impairment of the upper and lower extremities is common, which may be due to weakness or paralysis, sensory loss, spasticity, and abnormal motor synergies. In addition, a near 15% prevalence of sarcopenia has been found in people with stroke. Gait impairment has been observed in a high percentage of people with stroke, a dysfunction that may persist despite rehabilitation. More than 50% of people with stroke may experience limitations in activities such as shopping, housework, and difficulty reintegrating into community life within 6 months. These restrictions can result in a diminished health-related quality of life.
