Simplified motor scale
Purposeneurological evaluation

Simplified motor scales (SMS) refer to a neurological evaluation that is designed to provide a meaningful, objective prognostic evaluation of an individual. SMS have been proposed as alternatives that would improve upon the Glasgow Coma Scale challenges of being confusing, unreliable and unnecessarily complex. [1]

An example of a SMS can be remembered by the mnemonic "TROLL" for Test Responses: Obeys, Localizes, or Less.

The scale was created by Dr Stephen Green in 2011. He wrote an editorial for the Annals of Emergency Medicine strongly opposing the use of the GCS, stating that, compared to a general assessment, simple unstructured clinical judgement can be just as accurate and that the GCS itself has poor reliability. [2] «Literature evidence is now overwhelming that the Glasgow Coma Scale is unreliable, inaccurate and unnecessarily complex, as simpler scales are just as predictable. SMS is a useful part of the GCS, statistically cleaned up to eliminate bloat and with much greater reliability between experts.» [3] According to a study published in Annals of Emergency Medicine in 2014, an easier-to-use scale has little impact on the accuracy of diagnoses. The study was based on the prediction of the outcome of brain injuries: relative differences from the Glasgow Scale ranged from 3% to 7% with an average difference of 5%. [4] Other studies have reached similar results. [5] [6]

A coma is a deep state of prolonged unconsciousness in which a person cannot be awakened, fails to respond normally to painful stimuli, light, or sound, lacks a normal wake-sleep cycle and does not initiate voluntary actions. The person may experience respiratory and circulatory problems due to the body's inability to maintain normal bodily functions. People in a coma often require extensive medical care to maintain their health and prevent complications such as pneumonia or blood clots. Coma patients exhibit a complete absence of wakefulness and are unable to consciously feel, speak or move. Comas can be the result of natural causes, or can be medically induced.

In medicine, triage is a process by which care providers such as medical professionals and those with first aid knowledge determine the order of priority for providing treatment to injured individuals and/or inform the rationing of limited supplies so that they go to those who can most benefit from it. Triage is usually relied upon when there are more injured individuals than available care providers, or when there are more injured individuals than supplies to treat them.

<span class="mw-page-title-main">Head injury</span> Serious trauma to the cranium

A head injury is any injury that results in trauma to the skull or brain. The terms traumatic brain injury and head injury are often used interchangeably in the medical literature. Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that can cause head injuries.

The Glasgow Coma Scale (GCS) is a clinical scale used to reliably measure a person's level of consciousness after a brain injury.

<span class="mw-page-title-main">Brain injury</span> Destruction or degeneration of brain cells

Brain injury (BI) is the destruction or degeneration of brain cells. Brain injuries occur due to a wide range of internal and external factors. In general, brain damage refers to significant, undiscriminating trauma-induced damage.

<span class="mw-page-title-main">Major trauma</span> Injury that could cause prolonged disability or death

Major trauma is any injury that has the potential to cause prolonged disability or death. There are many causes of major trauma, blunt and penetrating, including falls, motor vehicle collisions, stabbing wounds, and gunshot wounds. Depending on the severity of injury, quickness of management, and transportation to an appropriate medical facility may be necessary to prevent loss of life or limb. The initial assessment is critical, and involves a physical evaluation and also may include the use of imaging tools to determine the types of injuries accurately and to formulate a course of treatment.

<span class="mw-page-title-main">Epidural hematoma</span> Build-up of blood between the dura mater and skull

Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain and the skull. When this condition occurs in the spinal canal, it is known as a spinal epidural hematoma.

<span class="mw-page-title-main">Traumatic brain injury</span> Injury of the brain from an external source

A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging from mild traumatic brain injury (mTBI/concussion) to severe traumatic brain injury. TBI can also be characterized based on mechanism or other features. Head injury is a broader category that may involve damage to other structures such as the scalp and skull. TBI can result in physical, cognitive, social, emotional and behavioral symptoms, and outcomes can range from complete recovery to permanent disability or death.

The AVPU scale is a system by which a health care professional can measure and record a patient's level of consciousness. It is mostly used in emergency medicine protocols, and within first aid.

<span class="mw-page-title-main">Intracerebral hemorrhage</span> Type of intracranial bleeding that occurs within the brain tissue itself

Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain, into its ventricles, or into both. An ICH is a type of bleeding within the skull and one kind of stroke. Symptoms can vary dramatically depending on the severity, acuity, and location (anatomically) but can include headache, one-sided weakness, numbness, tingling, or paralysis, speech problems, vision or hearing problems, memory loss, attention problems, coordination problems, balance problems, dizziness or lightheadedness or vertigo, nausea/vomiting, seizures, decreased level of consciousness or total loss of consciousness, neck stiffness, and fever.

Abnormal posturing is an involuntary flexion or extension of the arms and legs, indicating severe brain injury. It occurs when one set of muscles becomes incapacitated while the opposing set is not, and an external stimulus such as pain causes the working set of muscles to contract. The posturing may also occur without a stimulus. Since posturing is an important indicator of the amount of damage that has occurred to the brain, it is used by medical professionals to measure the severity of a coma with the Glasgow Coma Scale and the Pediatric Glasgow Coma Scale.

A rib fracture is a break in a rib bone. This typically results in chest pain that is worse with inspiration. Bruising may occur at the site of the break. When several ribs are broken in several places a flail chest results. Potential complications include a pneumothorax, pulmonary contusion, and pneumonia.

Etomidate is a short-acting intravenous anaesthetic agent used for the induction of general anaesthesia and sedation for short procedures such as reduction of dislocated joints, tracheal intubation, cardioversion and electroconvulsive therapy. It was developed at Janssen Pharmaceutica in 1964 and was introduced as an intravenous agent in 1972 in Europe and in 1983 in the United States.

The fencing response is an unnatural position of the arms following a concussion. Immediately after moderate forces have been applied to the brainstem, the forearms are held flexed or extended for a period lasting up to several seconds after the impact. The fencing response is often observed during athletic competition involving contact, such as combat sports, American football, ice hockey, rugby union, rugby league and Australian rules football. It is used as an overt indicator of injury force magnitude and midbrain localization to aid in injury identification and classification for events including on-field and/or bystander observations of sports-related head injuries.

The Ontario Prehospital Advanced Life Support (OPALS) Studies were a series of multi-center before-and-after clinical trials looking at the impact of prehospital advanced life support services. The studies have not found the addition of advanced life support services to increase survival to hospital discharge for cardiac arrest patients.

<span class="mw-page-title-main">Trauma in children</span> Medical condition

Trauma in children, also known as pediatric trauma, refers to a traumatic injury that happens to an infant, child or adolescent. Because of anatomical and physiological differences between children and adults the care and management of this population differs.

The FOUR Score is a clinical grading scale designed for use by medical professionals in the assessment of patients with impaired level of consciousness. It was developed by Dr. Eelco F.M. Wijdicks and colleagues in Neurocritical care at the Mayo Clinic in Rochester, Minnesota. "FOUR" in this context is an acronym for "Full Outline of UnResponsiveness".

Prehospital ultrasound is the specialized application of ultrasound by physicians and other emergency medical services (EMS) to guide immediate care and treatment procedures. Like conventional ultrasound, it is a device that produces cyclic sound pressure to penetrate a medium and reveal details about the inner structure of the medium.

Pain stimulus is a technique used by medical personnel for assessing the consciousness level of a person who is not responding to normal interaction, voice commands or gentle physical stimuli. It forms one part of a number of neurological assessments, including the first aid based AVPU scale and the more medically based Glasgow Coma Scale.

A pediatric concussion, also known as pediatric mild traumatic brain injury (mTBI), is a head trauma that impacts the brain capacity. Concussion can affect functional, emotional, cognitive and physical factors and can occur in people of all ages. Symptoms following after the concussion vary and may include confusion, disorientation, lightheadedness, nausea, vomiting, blurred vision, loss of consciousness (LOC) and environment sensitivity. Concussion symptoms may vary based on the type, severity and location of the head injury. Concussion symptoms in infants, children, and adolescents often appear immediately after the injury, however, some symptoms may arise multiple days following the injury leading to a concussion. The majority of pediatric patients recover from the symptoms within one month following the injury. 10-30% of children and adolescents have a higher risk of a delayed recovery or of experiencing concussion symptoms that are persisting.
