Expressive language recovery in aphasia using the Shewan Spontaneous Language Analysis (SSLA) system

The oral expressive language of a group of aphasic subjects was measured on two occasions approximately one year apart to determine what changes took place during this period and whether these changes were significant. The SSLA system was used to evaluate the aphasic language samples obtained from a picture description task. Positive changes toward normal language functioning occurred for several variables. Type of aphasia affected the outcome of several variables. The rank ordering of aphasia types from most to least impaired was similar across these variables, thereby suggesting similar outcome patterns. Initial severity of aphasia also influenced the outcome of several SSLA variables. However, the degree of concordance of the severity groups across variables was not statistically significant. Treatment had a positive effect on the outcome of only one SSLA variable. Possible explanations for these results are discussed.
