Activities-Specific Balance Confidence Scale
ABBR: ABC A 16-item instrument designed to measure a patient’s perceived level of confidence in performing common activities of daily living (ADLs) without losing balance and falling. The patient ranks his confidence to complete each item from 0% (no confidence) to 100% (complete confidence).
ASIA Impairment Scale
A method of assessing the degree of motor and sensory impairment in spinal cord injured patients. The assessment is based on an examination of the perineum and anus, i.e., on the S4-S5 level of the spinal cord. Grade: A—Complete: No motor or sensory function; Grade B—Incomplete, sensory function is intact, but motor function is absent below and including the S4-S5 level; Grade C—Incomplete, motor function is preserved below the neurological level and more than half of the primary muscles have a muscle grade test of less than 3; Grade D—Incomplete: Motor function is preserved and at least half of the muscles below the S4-S5 level have a muscle grade test of 3 or better; and Grade E—Normal.

scale of contrast
The range of densities on a radiograph; the number of tonal grays that are visible.
Disability Rating Scale
An instrument to gauge the functional capabilities and progress of a person with moderate to severe brain injury. A person who has no deficits after recovery from brain injury receives a score of 0 (not impaired). A severely impaired person who is unemployable, unable to care for himself, and unable to open his eyes, move, or speak receives the lowest score, 29.
Falls Efficacy Scale
falls efficacy scale ABBR: FES A questionnaire to assess the level of confidence that patients have in performing activities of daily living without fear of falling.
A system to indicate the diameter of catheters and sounds. Each unit on the scale is approximately equivalent to one-third mm; thus a 21 French sound is 7 mm in diameter. The size of the diameter of the catheter increases as the numerical value of French increases.
Geriatric Depression Scale
ABBR: GDS A 30-item questionnaire to screen for depression in older adults, e.g., when they first become eligible for Medicare.
Glasgow Coma Scale
ABBR: GCS A scale to determine a patient's level of consciousness. It is a rating from 3 to 15 of the patient's ability to open his or her eyes, respond verbally, and move normally. The GCS is used primarily during the examination of patients with trauma or stroke. Repeated examinations can help determine if the patient's brain function is improving or deteriorating. Many EMS systems use the GCS for triage and for determining which patients should be intubated in the field. SEE TABLE: Glasgow Coma Scale; SEE: coma; SEE: Trauma Score
Glasgow Outcome Scale
A scale that assesses current neurological awareness of the environment, and recovery and disability in all types of brain injury. The scale is used in the evaluation of trauma, stupor, or coma, and at prescribed time intervals, such as 3 months, 6 months, and 1 year after injury. The Glasgow group reports the greatest recovery in the 6-month period after injury. The nurse (or other health care practitioner) notes the patient's abilities at a particular time using this practical scale: Good outcome: may have minimal disabling sequelae but returns to independent functioning comparable to preinjury level and a full-time job; Moderate disability: is capable of independent functioning but not of returning to full-time employment; Moderate disability: is capable of independent functioning but not of returning to full-time employment; Severe disability: depends on others for some aspect of daily living; Persistive vegetative state: has no obvious cortical functioning; Dead.
Global Assessment of Functioning Scale
ABBR: GAF scale A scale that rates a person's social, occupational, and psychological functioning. The scale rates from high functioning, i.e., highly adapted and integrated to one's environment, to poorly functioning, i.e., self-destructive, homicidal, isolated, or lacking the rudiments of self-care. There is a children’s version of the scale, called the Children’s Global Assessment of Functioning (CGAF).
Global Assessment of Relational Functioning Scale
ABBR: GARF scale A measure of the degree to which a family meets the emotional and functional needs of its members.
An assessment tool for evaluating vocal problems, relying on a systematic analysis of a person's vocal grade, roughness, breathiness, ssthenia, and strain.
hydrogen ion scale
A scale used to express the degree of acidity or alkalinity of a solution. The classic pH scale extends from 0.00 (total acidity) to 14 (total alkalinity), the numbers running in inverse order of hydrogen ion (pH) concentration. The pH value is the negative logarithm of the hydrogen ion (pH) concentration of a solution, expressed in moles per liter.
As the hydrogen ion concentration decreases, a change of 1 pH unit means a 10-fold decrease in hydrogen ion concentration. Thus a solution with a pH of 1.0 is 10 times more acid than one with a pH of 2.0 and 100 times more acid than one with a pH of 3.0. A pH of 7.0 indicates neutrality. Very concentrated (>1 molar) mineral acids and bases go beyond the classic scale to values <0.00 and >14, respectively.
As the hydrogen ion concentration varies in a definite reciprocal manner with the hydroxyl ion (OH−) concentration, a pH reading above 7.0 indicates alkalinity. In the human body, arterial blood is slightly alkaline, having a normal pH range of 7.35 to 7.45.

Numerical Rating Scale
Numeric Rating Scale. ABBR: NRS A variation of the visual analog scale that uses a scalar numbering system to objectify a patient’s pain. Most numeric rating scales use a 10-cm line with tick marks spaced 1 cm apart. The leftmost mark is labeled “0” and has the notation “No Pain.” The rightmost mark is labeled “10” and the notation “Worst pain imaginable.” The patient is asked to indicate where on the continuum he or she would rate the current intensity of pain.
resource-based relative value scale
ABBR: RBRVS A scale for determining the monetary value of evaluation and management services provided to patients, i.e., services provided to patients by nonsurgeons. The scale is based on the total work required for a given service and on other considerations, including the cost of the physician's practice, the income lost during training, and the relative cost of liability insurance.

Stroke Impact Scale
Stroke Scale An instrument to measure the effect of a stroke on a person's mobility, speech, social activities, manual dexterity, strength, emotions, memory, and daily activities.
Unified Parkinson disease rating scale
ABBR: UPDRS An instrument that rates the severity of Parkinson disease. It consists of 42 items and measures the effects of the disease on a patient's activities of daily living, behavior, mentation, mood, movement, and the complications he or she may experience from treatment.
Vancouver scar scale
SEE: Burn scar index.
visual analog scale
An instrument to quantify a subjective experience, such as the intensity of pain. A commonly used visual analog scale is a 10-cm line labeled with “worst pain imaginable” on the right border and “no pain” on the left border. The patient is instructed to make a mark along the line to represent the intensity of pain currently being experienced. The clinician records the distance of the mark in centimeters from the left end of the scale.
