Filter by:Interpreting the published outcomes of hand function in total BPBI is confounded by a lack of clear documentation regarding detailed surgical findings and management strategies. Investigators have followed a well-defined protocol for surgical reconstruction with the primary objective being reinnervation of the lower trunk using the best available root. In this paper, Investigators outline the details of the strategy and provide a comprehensive analysis of the nerve reconstruction techniques and the resulting functional outcomes.
The goal of this observational study is to validate a risk prediction model developed for unsuccessful elbow flexion recovery after nerve transfer surgery in patients with brachial plexus injury. The main question it aims to answer is how well a risk prediction model perform in a different dataset, which are patients with brachial plexus injury who underwent surgery in a different time period or a different hospital.
Although peripheral nerve is capable of regrowth following injury, at only 1 mm/day, the slow rate represents a major barrier. Apart from rapid deterioration of the environment supportive of growth, denervated muscles become atrophic and bones osteoporotic. To successfully restore function, in addition to speeding up the nerve regeneration rate, treatments that can also restore muscle and bone mass are essential. Recently, in animal studies, the investigators showed that in addition to accelerating the speed of nerve regeneration, exercise training can also be used to restore muscle bulk and bone density. While promising, given the inter-species differences, the clinical utilities of this treatment need to be directly tested in humans. This will be done using a randomized controlled study design on patients with brachial plexus injury.
Evaluation of ultrasound as a diagnostic tool in assessment of patients with brachial plexus injuries before undergoing surgical exploration
The goal of this prospective observational study is to estimate the prevalence of brachial plexus injury after prone positioning in patients with ARDS and to evaluate the safety of swimmer position. The main questions it aims to answer are: - Could arm positioning during pronation play a role in the development of any nerve injury at the brachial plexus level? - Is swimmer position safe when adopted during prone positioning? Participants will be studied at selective time points using EMG assessment.
The objective of this study is to retrospectively evaluate the outcomes and clinical benefits provided by this brace to adult patients with upper limb impairment or paralysis due to brachial plexus, stroke (CVA), spinal cord injury, or other neurological disease or injury.
In daily life,people protect their tissues against ischemia by constantly changing positions. In situations that cause unconsciousness such as anesthesia,people cannot react to the stress or pressure due to immobility.This prolongation of immobility can lead to reversible or irreversible damage to the tissues.Therefore,not careful positioning in patients undergoing surgery can lead to serious complications.Peripheral nerve disorders are common in clinical practice.Electrodiagnostic studies continue to be the gold standard for the evaluation of nerve disorders.Elastography is a technique that measures the elastic properties of tissues as a new ultrasonography technology.Given the histological changes in diseased peripheral nerves, nerve elastography has begun to be studied as a noninvasive way to evaluate changes in nerve tissue composition.Elastography of the peripheral nerves has rarely been studied. Primary aim in this study is to compare the elastography values of the brachial plexus in different arm and head positions and to contribute to elucidating the mechanism of nerve damage due to position.American Society of Anesthesiologists (ASA) I-II volunteers between the ages of 18-65 will be recruited to the study.The bilateral brachial plexus of each volunteer will be examined.Participants with upper extremity or cervical trauma, muscle weakness,cervical disc herniation or a history of spine or cranial surgery, neuromuscular disease, clinical diagnosis of brachial plexopathies, hyperlipidemia,diabetes mellitus or radiotherapy history in the cervical region,body mass index> 35 will not be taken.Before the procedure, the muscle strength of the upper extremity and cervical muscles will be examined and volunteers with muscle weakness will be excluded from the study.Measurements will be made together by two researchers who have at least 5 years of experience in ultrasonography.Measurements will be made in 3 different positions.When the arm and head are in neutral position, the head is turned to the opposite side and the head is turned to the opposite side, the brachial plexus in the supraclavicular region will be visualized by ultrasonography while the arm is in hyperabduction.The area between the upper boundary and the lower boundary of the plexus will be marked, and the values will be taken 5 times consecutively with the share wave elastography method and the elastic modulus,shear wave velocity will be recorded.
The proposed research, the development of an innovative robotic hand orthosis with intelligent grasping control, is relevant to public health as it will restore a large measure of functionality to the paralyzed hand of a person who has suffered a brachial plexus injury. The proposed orthosis will utilize novel technology that will result in a device that is compact, portable, dexterous, and intuitively controllable while overcoming the disadvantages of previously developed orthoses that rendered them difficult to use. The restoration of functionality to ones hands will significantly improve their quality of life as well as their ability to again participate in the workforce and complete dexterous activities in their daily lives.
The purpose of this study is to assess pre- and postoperative neuropathic pain in patients with traumatic brachial plexus injuries to determine if intraoperative ketamine infusion affect neuropathic pain associated with avulsion injuries of the brachial plexus.
The objective of this study is to evaluate the therapeutic and functional gains of a myoelectric elbow-wrist-hand orthosis for adult individuals with upper limb impairments using repeated measures studies that combines both gross motion and quantitative function outcome measures.
