Active clinical trials for "Wounds and Injuries"

The purpose of this study is to evaluate the role of single dose 4-aminopyridine (4-AP) on the diagnosis of severing vs non-severing nerve injury after peripheral nerve traction and/or crush injury. The investigational treatment will be used to test the hypothesis that 4-aminopyridine can speed the determination of nerve continuity after peripheral nerve traction and/or crush injuries allowing the identification of incomplete injuries earlier than standard electrodiagnostic (EDX) and clinical assessment. Participants will be randomized to one of two groups to determine the order of treatment they receive (drug and placebo vs placebo and drug). Participants will undergo baseline testing for nerve assessment, receive either drug or placebo based on randomization and undergo hourly sensory and motor evaluation, EDX testing and serum 4AP levels for three hours after dosing. Participants will then repeat this with the crossover arm.

The aim of this study is elucidate genetic susceptibility of patients with traumatic brain injury (TBI) and symptoms of Brain Injury Associated Fatigue and Altered Cognition (BIAFAC) using genome-wide association study (GWAS).

Infection control and health-care-associated infections and Safety of medical service providers Evidence based management of common medical and surgical problems

This study is based on preclinical (animal) studies showing that infusing bone marrow-derived mesenchymal stem cells into the spinal fluid may contribute to improving neurologic function in animal models with spinal cord injuries. Bone marrow (BM) contains several types of stem cells that can produce functional cells. This includes cells that could help the healing process of damaged neurologic tissue. The primary objective of this study is to see if the injection of these cells, obtained from your own bone marrow, is safe. A secondary objective is to evaluate if the treatment can provide functional improvements (neuromuscular control and sensation) in the affected areas.

To demonstrate the superior effect of ES135 combined with spinal cord repairing surgery, compared to a placebo control with spinal cord repairing surgery, on post-surgery motor function recovery as measured by the changes from baseline of ISNCSCI Motor Scores in subjects

The overall purpose of this study is to quantify the effect and retention of one-week training of falling techniques on landing biomechanics associated with anterior cruciate ligament (ACL) loading compared to soft-landing techniques in young recreational athletes. The secondary purpose is to assess the safety of the training program. Aim 1: To quantify the effect of one-week training of falling techniques on landing biomechanics during forward, lateral, vertical, and diagonal landings compared to soft-landing techniques. We hypothesize that falling techniques will result in increased knee flexion angles and decreased landing forces, knee abduction and internal rotation angles, and knee moments for all landing directions compared to soft-landing techniques immediately after the training. Aim 2: To assess the retention effects of the falling techniques on landing biomechanics compared to soft landings. We hypothesize that the effects of falling techniques on ACL loading variables will be more highly retained compared to soft-landing techniques two weeks after the training. Aim 3: To identify the safety of the training program. We hypothesize that participants can complete the training without suffering minor, moderate, or major injuries, while occasional minor bruises might be observed.

This validation study investigates the diagnostic precision and accuracy when grading otic barotrauma using two alternative gradings systems including the TEED and the OGS grading systems. Background There are two grading systems used to grade otic barotrauma. They include the Teed Score (TEED) and the O'Neill Grading System (OGS). Teed has been utilized more extensively but among physicians has been found to have limitations. The OGS is an alternative grading system with less classification categories than what the Teed classification system utilizes. The OGS system is tied directly to treatment decision making, specific to the respective grading level. Methods This study will utilize a sample of clinical examiners who will independently grade 120 digital color photos of actual patient tympanic membranes with and without evidence of eustachian tube dysfunction and middle ear barotrauma including variable stages or grades of otic barotrauma. They will use the TEED chart as a reference in selecting the appropriate TEED score for each of the photos. Simultaneously they will also utilize the OGS chart as a reference in selecting the appropriate OGS grade for each of the photos. The grading will be conducted by physicians, nurses, and technicians. This will allow for comparisons at varying provider levels. The comparisons will be made using the kappa statistics across the disciplines. This will allow comparison between observed agreement, and expected agreement due to chance for all reviewers. Research Hypothesis Ho: There is no difference in diagnostic precision and accuracy when grading otic barotrauma between clinical examiners using either the TEED or OGS grading systems. Ha: There is a difference in diagnostic precision and accuracy when grading otic barotrauma between clinical examiners using either the TEED or OGS grading systems.

Even though females are 2- to 10-times more likely to suffer an anterior cruciate ligament (ACL) injury, males represent the largest population of total ACL injuries. Consequently, there is a larger population of males that endure significant pain, functional limitations, and radiographic signs of knee osteoarthritis (OA) within 12 to 20 years of injury. To reduce the burden of OA, The National Public Health Agenda for Osteoarthritis recommends expanding and refining evidence-based prevention of ACL injury. Specialized training that targets modifiable risk factors shows statistical efficacy in high-risk athletes; however, clinically meaningful reduction of risk has not been achieved. A critical barrier that limits successful training outcomes is the requirement of qualified instructors to deliver personalized, intuitive, and accessible feedback to young athletes. Thus, a key gap in knowledge is how to efficiently deliver objective, effective feedback during training for injury prevention. The investiagator's long-term goal is to reduce ACL injuries and the subsequent sequela in young male athletes.

The investigators will combine state-of-the-art quantitative imaging, on-field biomechanics, and computational analytics into the largest-of-its-kind study to assess hamstring strain injury (HSI) risk and recovery in elite collegiate football players. The study will take place over 3 years and enroll up to 560 student athletes from Division I (D1) teams: University of Wisconsin-Madison, Brigham Young University and the University of North Carolina-Chapel Hill.

A prospective cohort study (questionnaires), with an embedded case control study (neuropsychological assessments) in which the data is gathered within a timeframe of 3 years. A group of 700 patients and a group of 100 healthy volunteers will be participating.
