Active clinical trials for "Paralysis"

Objectives: We aim to clarify the role of diaphragm ultrasonography (DUS) in evaluating the outcome of surgical diaphragmatic plication (SDP) in adults with symptomatic unilateral diaphragmatic paralysis (UDP).

Cerebral palsy (CP) is a movement and posture disorder accompanied by sensory, perception, cognition, communication and behavioral disorders that cause activity limitations by causing various non-progressive disorders of the fetal or infant brain. Spastic CP, according to the affected area in the body; It is classified as hemiparetic, diparetic and is observed most frequently. Diparetic CP, on the other hand, is characterized by significant spasticity in the pelvis and lower extremities, mild hypertonus or spasticity in the upper extremities, and incoordination, mostly involving the lower extremities and some upper extremities.Although lower extremity involvement is observed in different degrees in children with diparetic CP, studies showing how upper extremity and hand functions are affected are insufficient.The aim of this study is to compare the effect of upper extremity functional skills on quality of life and participation levels in children with diparetic CP with their healthy peers.

Pain is the most common secondary condition in patients with CP and the most important factor associated with reduced health-related quality of life. Pain in adolescents with CP is reported approximately 50-75%. Despite being a condition that can be seen with such a high prevalence, it is difficult for researchers and clinicians to capture this subjective perception in CP, as the individual may be a small child, may be cognitively impaired, visually impaired, or have communication difficulties. For these reasons, unrecognized pain can have negative effects on quality of life and participation in daily living activities, both as a result of limited mobility resulting from pain itself and fear-driven avoidance of specific activities. Self-report of pain is appropriate for individuals with CP without cognitive impairment. However, depending on the severity of communication impairment, self-report may be limited or even impossible to obtain in individuals with severe CP. In the case of individuals with CP, self-report supplemented with parent report, when possible, is the recommended strategy. The aims of this study: (i) to explore what is known about the prevalence, location, intensity and the effect of pain on daily lives of adolescents with CP; (ii) to demonstrate the relation between pain, clinical and sociodemographic characteristics; (iii) to compare self-reports of pain with mothers'reports of their child's pain.

This study will compare the motor outcomes for five infants with asymmetrical hand function (AHF) who will receive two, three week episodes of standard care separated by a three week episode of mCIMT paired with Neuromuscular Electrical Stimulation. The results of this study will inform decisions on the feasibility and efficacy of the treatment for use in a larger study for infants with AHF at risk for unilateral cerebral palsy.

The On Track Study is a large multi-site collaboration involving researchers, therapists, families, and children with cerebral palsy (CP) from across Canada and the United States. The researchers need to better understand how young children who have difficulties with movement activities progress and develop in their balance abilities, fitness, strength, health, range of motion, self-care, everyday play, and activity participation. This study will determine how young children with cerebral palsy or gross motor delays progress in many aspects of their physical development and participation in daily life. The information collected from this study will help therapists and parents monitor if a child is developing as expected in his or her physical development and participation. Then, the health care professionals working with children can use the results of this study, in combination with the previously completed Move & PLAY study results, to provide the services that are most beneficial and meaningful for each child and their family members.

Several methods exist to evaluate motor function in the child with cerebral palsy and are used to assess the outcome of a clinical intervention. However, these scales are not directed towards measuring the changes in muscle activity patterns that can result from the intervention. For example, there are classification scales aimed at measuring motor function and functional abilities, and indices of gait function. These scores, while providing a way to quantify function and mechanics, do not directly measure muscle activation characteristics. Therefore, these tests may be insensitive to how the intervention has directly affected muscle function, which is usually the focus of the intervention (i.e. botulinum toxin, functional electrical stimulation, dorsal rhizotomy). Muscle biopsies and motor evoked potentials can provide information about the muscle activation characteristics, however, they are invasive and there are concerns about using these techniques on the pediatric population and/or the practicality of clinical implementation, especially since they do not provide insight into how the muscle behaves during a functional task. One method that can be used to provide insight into muscle activity in a non-invasive and clinically meaningful manner is the use of surface electromyography (sEMG). Surface EMG is typically a routine part of clinical assessment and the evaluation of motor impairment in CP. However, the analysis of the data has been limited in most cases to examination of signal amplitude or differences in muscle onset and offset timing. The long-term goal of this research is to develop an analysis method for sEMG that can be used during functional tasks for treatment planning, diagnostic, assessment purposes in CP. This is to be accomplished through the use of the continuous wavelet transform (CWT). By developing an assessment method based on muscle activity, it is believed that a clinically viable measurement tool can be devised that will provide a level of insight into the effects of an intervention on muscle pathophysiology that is not currently available. The first step in progressing towards this long-term goal is to determine the variability and range of expected time-frequency patterns that can be expressed in a given population (i.e., cerebral palsy) during the execution of a meaningful task (gait), and relate the time-frequency information back to more standard assessments

This study will examine how the brain controls movements in patients with certain types of cerebral palsy. In healthy people, one side of the body usually controls movements on the other side of the body. In patients with cerebral palsy, this pattern may be altered, and one side of the brain may control movements on the same side of the body. Information obtained from this study may lead to improved rehabilitation therapy strategies for patients with cerebral palsy. Healthy volunteers and patients with cerebral palsy between 6 and 18 years of age may be eligible for this study. All candidates will be screened with a medical history, physical examination, and psychological testing. In addition, patients with cerebral palsy will have hearing and vision tests, a review of their medical records, and a magnetic resonance imaging (MRI) scan if one has not been done within the past year. For this test, the patient lies on a table that slides into a narrow metal cylinder with a strong magnetic field (the scanner). The scanning time usually lasts between 45 and 90 minutes. Patients enrolled in the study also will be evaluated by a physiatrist and physical and occupational therapists. They will be examined for muscle stiffness and reflexes. Their gait and movements (e.g., how they pick up a glass of water) will be evaluated. They will be asked about their ability to perform activities around the house and at school and whether a wheelchair or walker is needed to get around. Patients may also be asked about how they are dealing with their movement problems and how it affects their caregivers. All participants will undergo three tests, described below, to evaluate movement control. The first two tests use electrodes (small metal discs) taped to the skin over the muscles in both hands to measure muscle activity. A small disc placed on the fingers detects and measures the hand movements. The third test uses magnetic pulses that stimulate the brain to study how the brain controls movements. Quantitative test of fine motor function: For this test, the subject taps buttons at different speeds on a box attached to a computer. The test is similar to playing simple computer games. Long latency reflexes: For this test, the subject's hand is lightly strapped into a holder that holds the hand still while a motor moves the index finger with sudden small movements. These reflexes may also be tested using a gentle shock to the finger delivered through a ring electrode. Transcranial magnetic stimulation: For this test, the subject sits in a comfortable chair. An insulated coil is held on the scalp. A magnetic pulse from the coil stimulates the brain. The subject may hear a click and feel a snap or pulling sensation on the scalp under the coil. The stimulation may also cause twitching in the muscles of the arm or leg. During the stimulation, the subject may be asked to move certain muscles or perform other simple actions.

Children with symptomatic HIV-1 (Human Immunodeficiency Virus) infection are at increased risk for developing severely disabling neurological and neuropsychological deficits. HIV-1 related CNS (Central Nervous System) disease is a clinical syndrome, manifested by varying and sometimes discordant degrees of cognitive, motor and behavioral impairment. A continuum of clinical presentations attributed to the effects of HIV-1 infection on the CNS, ranging from apparently normal development, decreases in the rate of new learning to the loss of acquired skills have been observed. Two domains of psychological functioning appear most susceptible to the effects of HIV infection on the central nervous system in children: expressive behavior and attentional processes (Brouwers, et al, 1994). Attention deficits have been documented as a relative weakness on the "freedom from distractibility" subclass of IQ tests (Brouwers et al, 1989) and on behavior assessment (Moss et al, 1994). Attention, however, has many subcomponents such as focused attention, divided attention, vigilance, etc. Direct assessment of attentional functioning using reaction time has not yet been conducted and questions whether attentional components are differentially affected by the virus have not been addressed. The proposed study would assess different components of attentional functioning in children with HIV-1 disease. A quantitative and systematic method is developed that could complement the existing standardized instruments used for measuring attention and neurocognitive function in this population. Simple alerted visual reaction time will be measured with varying preparatory intervals, a two-choice reaction time in a go/no-go paradigm will be administered, and a continuous performance, divided reaction time test and an object decision task will be given. Performance on these measures will also be related to measures of brain structure and stage of HIV-1 disease.

This is a feasibility study to alter the Microsoft Kinect software to be used as a rehabilitation tool. The prototype used is still in the early developing stage. The purpose of this research study is to develop a prototype of altered Microsoft Kinect Software and determine its use in improving the function of the study subjects' weaker extremities. The altered software will allow a viewing of the mirror image of the involved limb as it is moved. However, the image that is viewed will reflect normal movement even if the limb cannot move normally. By viewing normal movement of the weaker limbs the "mirror neuron" network in the brain will become activated and will ultimately improve the function of the weaker side.

This observational study aims to early identify, through a rigorous and standardized follow-up, infants at high risk for Cerebral Palsy. After the consent agreement firmed by the parents, infants born at term or preterm with ultrasonographic evidence of brain injury considered at risk for neurodevelopmental disorders will be strictly monitored during the first months of life performing a periodic neurological assessment (Prechtl's General Movement (GMA) and the Hammersmith Infant Neurological Examination) at term age and around 3 months of post term age. Moreover, to study more accurately the brain injury early identified by ultrasonographic brain exam, around 6 weeks of post-term age the enrolled infants will perform, as recommended in infants at risk, brain Magnetic Resonance (RM). Thanks to the high predictability power of the combination of the clinical observation with the neuroimaging infants at high risk of CP will be early detect. Selected infants, considered at high risk for CP will have the opportunity to perform an home based and family centered early intervention later than 3 post term age.
