“…Five writing therapy studies aimed to improve written syntax (Jacobs & Thompson, 2000;Mitchum et al, 1993;Murray & Karcher, 2000;Murray et al, 2007;Salis & Edwards, 2010). The syntactic structures targeted included subject-verb (SV; Salis & Edwards, 2010), subject-verb-object (SVO; Mitchum et al, 1993;Murray & Karcher, 2000;Salis & Edwards, 2010), object cleft (Jacobs & Thompson, 2000, p. 6), passive sentences (Jacobs & Thompson, 2000), and object-and subject-extracted embedded who-question sentences (Murray et al, 2007). The studies had either single (4) or multiple (1) case study designs and participants had either nonfluent aphasia (Jacobs & Thompson, 2000;Mitchum et al, 1993;Murray et al, 2007), Wernicke's aphasia (Murray & Karcher, 2000), or both expressive and receptive language impairments (Salis & Edwards, 2010).…”
