General Health Questionnaire

Patient-completed screening instrument for detecting current, diagnosable non-psychotic/psychiatric illnesses. Covers 4 elements of distress: depression, anxiety, social impairment, hypochondriasis. It is scored on a 0 - 90 scale

Geriatric Depression Scale (GDS)

Patient or observer-completed questionnaire for assessment of depression in older people. 30 items answered in yes/no format, relating to present time or past week and point scored; interpretation of scores stated. Shorter 15-item questionnaire validated from GDS, identified as GDS-15 or Mood Scale. Used as screening tool or for weekly reviews in treatment outcome studies.

Geriatric Functional Rating Scale (GFRS) 

The Geriatric Functional Rating Scale (GFRS) can be used to evaluate the functional capacity of an elderly patient. This can help identify those patients who are able to function alone or with some assistance from those WHO require institutionalization. The authors were from the McGill University and Royal Ottowa Hospital in Canada.

Get-up and Go Test,
Timed Up and Go Test (TUAG)

Staff-completed functional test of balance. Subjects complete a sequence of movements and are observed for deviation from a confident, normal performance. Subject starts sitting in a chair, then rises, stands still momentarily, walks to a wall (3m away), turns without touching the wall, walks back to chair, turns and sits down. Graded on a 5-point scale (1 = normal, 5 = severely abnormal). A score of 3 or more indicates a person at risk of falling

Glasgow Coma Scale (GCS); clinimetric properties
Staff-completed scale for assessing depth and duration of impaired consciousness and coma recorded on a staff-completed chart. Three aspects of behaviour are recorded - motor responses, verbal responses and eye opening; each charted on a 5-point scale in a graphical form. Research shows high levels of consistency between different observers

Glasgow-Liege Scores

The Glasgow-Liege Scores combines the status of the brain stem reflexes and the Glasgow Coma Scale. From this score it is possible to estimate the probability of a comatose patient's outcome

Glasgow Outcome Scale
Staff-completed measure of disability. Original scale proposes 4 outcome categories: vegetative state, severe disability, moderate disability and good recovery. Modified scale adds a 'better', 'worse' subdivision of disability and recovery categories. Disability is assessed on physical deficits: epilepsy, cranial nerve palsy, ataxia, hemiparesis, dysphasia and homonymous hemianopia. Psychosocial deficits assessed include cognition, personality, memory and IQ

Goal Attainment Scaling / Scale (GAS)

Staff-completed but individualised criterion-referenced measure to quantify achievement of specific goals of treatment, expressed as behavioural objectives. Goals are set by therapists with patients and carers, and have a 5-point ordinal scale of attainment with 2 levels above and 2 below the principle goal

Grading Injury Severity Based on Functional Impairment

The severity of an injury can be graded based on how it impacts the athlete's performance and activities. This impacts the amount of time it takes for the person to recover

Grading of Ankle Sprains (Kumbhare and Basmajian)

Kumbhare and Basmajian included a scale for grading the severity of an ankle sprain based on the physical examination. This can be used to evaluate the patient initially and to monitor healing and the response to interventions

Grading the Severity of Chronic Pain (von Korff)

The severity of chronic pain can be graded based on its characteristics and its impact on a person's activities

Groningen Activity Restriction Scale
Staff / Patient-completed scale for assessing disability in older people. 18 items administered in a face to face interview using a mandatory card with response options, or mailed questionnaire. Each item differentiates between personal disability and situational restriction. There are 4 response categories, each weighted to provide a summed final score. Possible scoring ranges from 18 to 72

Gross Motor Function Classification System of Palisano  for Assessing Mobility in a Child 6 to 12 Year of Age With Cerebral Palsy
Palisano et al used a classification system for gross motor function to describe mobility in children with cerebral palsy

Guttman scale for the assessment of mobility in MS

De Souza developed a Guttman-type scale for evaluation of mobility disability in patients with multiple sclerosis. The scale was developed in terms of biomechanics and the neural control of movement. The author is from Brunel University in England.

Guy's Hospital Prognostic Score; Allen's Prognostic Score for Stroke
Staff-completed disease-specific measurement for prognosis of acute stroke. Assigns predetermined scores to factors of age and presenting clinical features found to predict functional dependence, in order to make a prediction of outcome. The final score is presented as a percentage likelihood of regaining functional independence.
