The functional assessment scales are important to express the sevenity of the disability and to evaluate the results of the management in the rehabilitation medicine. Many kinds of functional assessment scales were suggested. But Modified Barthel Index (MBI) and PULSES profile have been used commonly in Korea. Both scales are useful for measuring functional levels of self-care and mobility in physically impaired, however these indicls are not adjustable to evaluation of disability in severely handicapped individuals. So Functional Indepandence Measure (FIM) and Edinburgh Rehabilitation Status Scale (ERSS) were developed and published recently each in United States and New Zealand.

The number of patients were 14 inpatients and 24 outpatients who performed the rehabilitation program in the department of rehabilitation medicine. Fifteen of them had brain damage and twenty-three had spinal card injury. Four kinds of the scales were applied in each patients at the same time. Four scales were MBI, PULSES profile, FIM and ERSS.

Four scales evaluated their canacity and the characteristics of functional assesment.

The following results were obtained.

1) MBI and FIM are considered as concordant funocional scaie to follow the change of the disability in the same disease categary. This is statistically significant (P<0.01).

2) MBI is more useful in the patien of spinal cord injury and FIM in the patients of brain damage respectively because of saving the time are checking the mental function.

3) PULSES profile, that inciudes the function to assess the impairment, had the high correlation with the MBI and FIM but no discrimination function between them statistically.

4) ERSS is useful in measuring the hadicaps as well as the ability to assess the functional activity and the sensitivity to discriminate the disability is weak relatively.

In, conclusion, the measurement of both ERSS and other one of MBI and FIM was known to satisfy the functional measuring of generally disabied patients.
