Purpose
The SSAM was developed as a tool for measuring the senses of an unconscious patient over a long period of time. It is intended to assist in treatment planning and to address the demands of scientific research.
- 5 scales consistent with the 5 senses:
1) visual
2) auditory
3) tactile
4) gustatory
5) olfactory
- Each item scored based on intensity of response to stimuli in 3 categories:
1) eye opening
2) motor
3) vocalization
- No invasive, noxious, or painful stimulation used.
- Scoring guidelines:
1) 15 items
2) Minimum score= 15
3) Maximum score = 90
- Each response scale is hierarchically arranged:
1) Lowest score assigned to responses that reflect no change from baseline behavior.
2) Highest score represents the patient’s ability to use behaviors as communication with acceptable reliability and consistency.
- Description of response categories (eye opening, motor, and vocalization) is found on p. 313 in Rader & Ellis, 1994, and a summary table is on p. 316.
- Pen light
- Common objects
- Extracts: strawberry, almond, orange, lemon, baking soda, and chocolate
- Hot and cold items

Professional Association Recommendation
Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Multiple Sclerosis Taskforce (MSEDGE), Parkinson’s Taskforce (PD EDGE), Spinal Cord Injury Taskforce (PD EDGE), Stroke Taskforce (StrokEDGE), Traumatic Brain Injury Taskforce (TBI EDGE), and Vestibular Taskforce (Vestibular EDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

Considerations
According to the American Congress of Rehabilitation review of outcome measures, the expert panel concluded that the SSAM has well-defined administration and scoring procedures that facilitate consistent use (Seel et al, 2010). Overall, they recommend that the SSAM may be used to assess DOC with moderate reservations, because of concerns about possible bias in determining reliability (unblended assessors). This recommendation is supported by expert consensus that the SSAM has acceptable content validity and acceptable standardized administration and scoring procedures.
