Filter by: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.
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.
Brachial plexus block is a common regional anesthesia technique which is performed by anesthesiologists to anesthetize the arm for surgery. In this study, we are investigating the relationship between the nerve conduction (induced by brachial plexus block) and the patients' symptoms before and after the brachial plexus block. We will attach a nerve conduction device (SSEP device) to monitor the patients' arm conduction and we will assess the patients' symptoms simultaneously.
To evaluate the surgical repercussions in patients with traumatic brachial plexus injury in the respiratory and motor systems, trunk biomechanics, functional capacity and quality of life.
Brachial plexus avulsion injury (BPAI) caused by traction injury, especially total root avulsion, represents a severe handicap for the patient. Despite recent progress in diagnosis and microsurgical repair, the prognosis in such cases remains unfavorable. We need to find an relatively optimal surgical treatment.
Intracranial Pressure ( ICP ) monitoring is an essential component of traumatic brain injured ( TBI ) patients management. The clinical signs of raised ICP may be unreliable and may reflect relatively late cerebral decompensation. ICP may be monitored by invasive or non invasive techniques. While invasive techniques show the real time values of ICP, they are associated with many complications like, intracranial bleeding and infection, occlusion of the catheter tip by blood, debris and difficult to locate ventricle in presence of cerebral oedema. All these drawbacks of invasive methods can be averted by employing non invasive techniques of ICP monitoring. Although they do not show a real time value but are excellent tools to detect presence or absence of raised ICP. Elevated ICP can be detected by Computarised tomographic scan (CT) or Magnetic resonance imaging (MRI) but , these techniques are time consuming and require transportation of a patients who may be unstable .The quick and non invasive nature of ultrasonography is fast becoming popular for rapid detection of elevated ICP at bedside in emergency and ICU by monitoring the optic nerve sheath diameter ( ONSD ). Its limitations notwithstanding, ultrasonographic ONSD monitoring is likely to be more reliable than clinical assessment in the diagnosis of intracranial hypertension especially, when patient is under sedation which precludes proper clinical examination. Therefore, in recent years ,among non invasive methods, bedside ocular ultrasonography to monitor ICP has gained popularity. Carbon dioxide being a potent modulator of cerebral vascular tone, alters the ICP by changing the size of cerebral vasculature and thereby, cerebral blood flow (CBF) and this action occurs very rapidly, over e period of few minutes. In a range of PaCO2 20mmHg to 80 mmHg the cerebral blood flow changes in a linear manner. End tidal carbon dioxide concentration(EtCO2) is a surrogate measure of PaCO2 (especially in a haemodyanimically stable patient with healthy lungs ) and is routinely monitored continuously in patients subjected to general anaesthesia. To date there is very little literature on the effects changing EtCO2 on ONSD . This prompted us to conduct this study to find out the effects of different levels of EtCO2 on ONSD.
The purpose of this research study is to demonstrate that individuals with upper limb paralysis due to spinal cord injury, brachial plexus injury, amyotrophic lateral sclerosis and brain stem stroke can successfully achieve direct brain control of assistive devices using an electrocorticography (ECoG)-based brain computer interface system.
