A Registered Cohort Study on Spastic Paraplegia
Spastic ParaplegiaThe aim of this study is to determine the clinical spectrum and natural progression of Hereditary Spastic Paraplegias(HSP) and related disorders in a prospective multicenter natural history study, to assess the clinical, genetic and epigenetic features of patients with Spastic Paraplegias to optimize clinicalmanagement..
Hereditary Spastic Paraplegia Genomic Sequencing Initiative (HSPseq)
Hereditary Spastic ParaplegiaNeurodegenerative Diseases5 moreThe purpose of the HSP Sequencing Initiative is to better understand the role of genetics in hereditary spastic paraplegia (HSP) and related disorders. The HSPs are a group of more than 80 inherited neurological diseases that share the common feature of progressive spasticity. Collectively, the HSPs present the most common cause of inherited spasticity and associated disability, with a combined prevalence of 2-5 cases per 100,000 individuals worldwide. In childhood-onset forms, initial symptoms are often non-specific and many children may not receive a diagnosis until progressive features are recognized, often leading to a significant diagnostic delay. Genetic testing in children with spastic paraplegia is not yet standard practice. In this study, the investigators hope to identify genetic factors related to HSP. By identifying different genetic factors, the investigators hope that over time we can develop better treatments for sub-categories of HSP based on cause.
Prognosis and Diagnosis of Spasticity in Acute-post Stroke Patients
StrokeAcute4 moreSpasticity, or greater muscle resistance, is a major disabling condition following stroke. Recovery of lost motor function in patients with stroke may be affected by spasticity, which most commonly develops in elbow and ankle muscles. However, despite its clinical relevance, the natural development of spasticity over the first 3 months after stroke is not clearly understood. Indeed, common clinical measures of spasticity such as the Modified Ashworth Scale (MAS) do not take into account the neurophysiological origin of spasticity and lack reliability and objectivity. The objective of this study is to examine the natural history of the development of spasticity among patients with stroke over the first 3 months using a new neurophysiological measure (TSRT, the tonic stretch reflex threshold angle) and its velocity sensitivity (mu) in comparison to MAS and other common clinical tests. In addition, detailed brain imaging will be used to understand the relationship between damage to brain regions relevant to the development of spasticity and TSRT/mu values. It is hypothesized that 1) TSRT/mu will indicate the presence of spasticity earlier than MAS/clinical tests; 2) TSRT/mu measures will be more closely related to motor impairments and activity limitations than MAS; 3) the lesion severity (identified by imaging) will be related to the change in TSRT/mu values. Outcomes will be measured in a pilot cohort of 12 patients hospitalized for first-ever stroke. Measurements will be taken at the bedside within the 1st week of the patient's admission and will be done once per week for 12 weeks with a follow-up at week 16. Brain Imaging will be done around the 6th week post-stroke.
Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford...
Rare DisordersUndiagnosed Disorders316 moreCoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.

Hereditary Spastic ParaplegiaThe aim of this study is to determine the clinical spectrum and natural progression of Hereditary Spastic Paraplegias (HSP) and related disorders in a prospective multicenter natural history study, identify digital, imaging and molecular biomarkers that can assist in diagnosis and therapy development and study the genetic etiology and molecular mechanisms of these diseases.
Untreated Sleep Apnea as an Aggravating Factor for Other Secondary Medical Conditions After Spinal...
Sleep ApneaSpinal Cord Injuries4 moreThis cross-sectional prospective study will assess the potential association of more severe sleep apnea after spinal cord injury with more intense neuropathic pain, more severe spasticity, and more significant cardiovascular abnormalities including cardiac arrhythmias and blood pressure fluctuations. In addition, the participants' experience when undergoing home-based sleep screening test or hospital-unattended sleep screening test will be assessed in a semi-structured interview.
Natural History Study of Patients With HPDL Mutations
Mitochondrial EncephalomyopathiesHereditary Spastic Paraplegia5 moreThis study uses medical records that allow retrospective data extraction of clinical manifestation to assess the natural history of HPDL mutations
Validation of a Spasticity Measurement Tool
StrokeThe objective of this project is to investigate the validity of a handheld spasticity measurement tool against standard clinical measurements of spasticity. We propose the testing apparatus will accurately provide an equivalent clinical measure of spasticity while also providing a more precise estimation of spastic response in persons with stroke.
