a
Numbers denote values on a Likert scale where 0 = no, 1 = less than 1 year, 2 = 1–3 years, 3 = 4–6 years, 4 = 7–10 years, and 5 = more than 10 years of training/playing.
b
Numbers denote values on a Likert scale with a range 0 (does never) to 5 (does daily).
c
Classification based on the Boston Diagnostic Aphasia Examination—Aphasia Severity Rating Scale.
