Table 1.
Demographics, aphasia test results, and percent phonemic errors on a motor speech examination (motor speech accuracy). Results are presented for each of the diagnostic groups separately.
| Variable | Participant group |
|||
|---|---|---|---|---|
| AOS | BORD1 | BORD2 | APH | |
| Sample size (n) | 37 | 30 | 29 | 37 |
| Sex (M:F) | 18:19 | 22:8 | 16:13 | 33:4 |
| Age (years) | 61 (52–69) | 60 (50–70) | 58 (53–68) | 63 (53–70) |
| Months postonset | 35 (18–66) | 30 (11–93) | 30 (8–66) | 33.5 (34.8) |
| WAB-R AQ /100 | 70 (49–85) | 71 (50–90) | 70 (55–88) | 83 (62–93) |
| Motor speech accuracy (%) | 83 (75–89) | 90 (85–97) | 89 (82–92) | 96 (89–98) |
Note. Values indicate medians, and interquartile ranges are reported in parentheses. Motor speech accuracy is the percentage of target phonemes produced correctly on the single word repetition section of the motor speech evaluation. AOS = profile most consistent with apraxia of speech; BORD1 and BORD 2 = borderline or inconclusive profile; APH = profile most consistent with aphasia without AOS; WAB-R AQ = Western Aphasia Battery–Revised Aphasia Quotient (Kertesz, 2006).
