Instruments such as the disability rating scale
(DRS), the functional independence measure (FIM), the Rancho Los Amigos levels of cognitive functioning scale (LCFS), and the community integration questionnaire (CIQ) were used in these studies and are commonly employed in rehabilitation settings to measure the level of disability in the patient who has sustained a head injury.
The specific research questions addressed were (a) Will there be an increase in arousal between initial assessment (baseline) and discharge assessment scores as measured by the Glasgow Coma Scale (GCS), Sensory Stimulation Assessment Measure (SSAM), Ranchos Los Amigos Level of Cognitive Functioning Scale (RLA), and Disability Rating Scale
(DRS) in patients who receive an auditory sensory stimulation program?
The Disability Rating Scale
(DRS) was developed to provide quantitative information to chart the progress of severe head-injured participants especially those who are between early arousal and salient functioning. The first three categories are similar to the GCS, eg, eye opening, best verbal response and motor response; the five remaining categories measure instrumental and activities of daily living as well as work abilities.
