“…Similar methodology to that employed in past EMA investigations conducted within the Motor Speech Research Centre was employed in the present study (e.g. Goozée, Murdoch, Theodoros, and Stokes, 2000;Bartle-Meyer et al, 2008).…”

“…As described in previous investigations conducted by the principal researcher (e.g. Bartle-Meyer et al, 2008), A1 was diagnosed with a moderate-severe AOS with a mild oral apraxia. A1 was rated as having no impairment in sub-test 2A (increasing word length-1) of the ABA-2; however, this was due to A1's significant difficulties with mono-and multisyllabic words.…”

“…Peak velocity was also reportedly unimpaired during bilabial stop production in multisyllabic utterances (McNeil and Adams, 1991). Importantly, it must be acknowledged that deviant articulatory parameters have also been reported during monosyllabic word production (Itoh, Sasanuma, Hirose, Yoshioka, and Ushijima, 1980;McNeil, Caligiuri, and Rosenbek, 1989;Robin, Bean, and Folkins, 1989;Mauszycki, Dromey, and Wambaugh, 2007;Bartle-Meyer, Goozée, and Murdoch, 2008).…”

Additionally, the control speakers and the participants with AOS were both expected to exhibit a word length effect during target consonant production to indicate a preserved phonological system.…”

The current study aimed to use electromagnetic articulography (EMA) to investigate the effect of increasing word length on lingual kinematics in acquired apraxia of speech (AOS). Tongue-tip and tongue-back movement was recorded for five speakers with AOS and a concomitant aphasia (mean age = 53.6 years; SD = 12.60) during target consonant production (i.e. /t, s, k/ singletons; /kl, sk/ clusters), for one and two syllable stimuli. The results obtained for each of the participants with AOS were individually compared to those obtained by a control group (n = 12; mean age = 52.08 years; SD = 12.52). Results indicated that the participants with AOS exhibited longer movement durations and, in some instances, larger tongue movements during consonant singletons and consonant cluster constituents embedded within mono- and multisyllabic utterances. Despite this, two participants with AOS exhibited a word length effect that was comparable with the control speakers, and possibly indicative of an intact phonological system.

“…Apraxic speech articulation and articulatory coordination have long been areas of interest among researchers and have been investigated kinematically (Bartle-Meyer, Goozée, Murdoch, & Green, 2009;Itoh, Sasanuma, & Ushijima, 1979) and using electropalatography (EPG; BartleMeyer, Murdoch, & Goozée, 2009;Hardcastle, Gibbon, & Jones, 1991;Howard & Varley, 1995). Although these modalities provide useful information about articulatory movement and contact patterns in apraxic speech, they are invasive by nature and do not provide the researcher with a dynamic view of the entire vocal tract during speech.…”

Purpose: Real-time magnetic resonance imaging (MRI) and accompanying analytical methods are shown to capture and quantify salient aspects of apraxic speech, substantiating and expanding upon evidence provided by clinical observation and acoustic and kinematic data. Analysis of apraxic speech errors within a dynamic systems framework is provided and the nature of pathomechanisms of apraxic speech discussed. Method: One adult male speaker with apraxia of speech was imaged using real-time MRI while producing spontaneous speech, repeated naming tasks, and self-paced repetition of word pairs designed to elicit speech errors. Articulatory data were analyzed, and speech errors were detected using time series reflecting articulatory activity in regions of interest.Results: Real-time MRI captured two types of apraxic gestural intrusion errors in a word pair repetition task. Gestural intrusion errors in nonrepetitive speech, multiple silent initiation gestures at the onset of speech, and covert (unphonated) articulation of entire monosyllabic words were also captured. Conclusion: Real-time MRI and accompanying analytical methods capture and quantify many features of apraxic speech that have been previously observed using other modalities while offering high spatial resolution. This patient's apraxia of speech affected the ability to select only the appropriate vocal tract gestures for a target utterance, suppressing others, and to coordinate them in time.
