“…These outcomes differ from reports indicating poorer intelligibility for monologue in PD, compared with tasks such as reading words and sentences (Canter & Van Lancker, 1985;Kempler & Van Lancker, 2002;Sidtis et al, 2012). Their findings also differ from limb motor control studies reporting that externally cued movements for individuals with PD are superior to self-initiated movements (BurleighJacobs, Horak, Nutt, & Obeso, 1997;Cunnington, Iansek, & Bradshaw, 1999;Lehman, Toole, Lofald, & Hirsch, 2005;McIntosh, Brown, Rice, & Thaut, 1997;Morris & Iansek, 1996;Thaut et al, 1996). These discrepancies may be due, in part, to differences in methodology (e.g., rating scales vs. transcription of utterances; the experience level of the listeners, etc.)…”

Purpose: The purpose of this study was to examine the effects of an internally versus externally cued speech task on perceived understandability and naturalness in speakers with Parkinson's disease (PD) and cerebellar disease (CD). Method: Sentences extracted from a covertly recorded conversation (internally cued) were compared to the same sentences read aloud (externally cued) by speakers with PD and a clinical comparison group of speakers with CD. Experienced listeners rated the speech samples using a visual analog scale for the perceptual dimensions of understandability and naturalness. Results: Results suggest that experienced listeners rated the speech of participants with PD as significantly more natural and more understandable during the reading condition. Participants with CD were also rated as significantly more understandable during the reading condition, but ratings of naturalness did not differ between conversation and reading. Conclusions: Speech tasks can have a pronounced impact on perceived speech patterns. For individuals with PD, both understandability and naturalness can improve during reading tasks versus conversational tasks. The speech benefits from reading may be attributed to several mechanisms, including possible improvement from an externally cued speech task. These findings have implications for speech task selection in evaluating individuals with dysarthria.This special issue contains selected papers from the March 2016 Conference on Motor Speech held in Newport Beach, CA. I t is well established that individuals with Parkinson's disease (PD) have difficulty performing skilled movement when forced to rely on internal cues versus responses guided by external cues or stimuli, such as a line on the floor to guide gait patterns (Gowen & Miall, 2007;Ketcham, Hodgson, Kennard, & Stelmach, 2003;Majsak, Kaminski, Gentile, & Flanagan, 1998;Morris, 2000;Sawamoto, Honda, Hanakawa, Fukuyama, & Shibasaki, 2002;Van Donkelaar et al., 2000). Most attribute this difficulty to dopaminergic deficits affecting the basal ganglia and fronto-striatal networks, which are involved in the preparation of internally generated movements (Cunnington, Iansek, Bradshaw, & Phillips, 1995;Lewis, Byblow, & Walt, 2000;Morris, 2000;Schenk, Baur, Steude, & Bötzel, 2003). As a result, individuals with PD become overly reliant on visual/auditory external stimuli to guide skilled movement (Romero, Van Gemmert, Adler, Bekkering, & Stelmach, 2003). Converging evidence suggests marked improvement in performance with external cueing for behaviors such as walking (Luessi, Mueller, Breimhorst, & Vogt, 2012;Mak, Yu, & Hui-Chan, 2013), writing (Oliveira, Gurd, Nixon, Marshall, & Passingham, 1997Teulings, Contreras-Vidal, Stelmach, & Adler, 1997), and driving (Scally et al., 2011; Stolwyk, Triggs, Charlton, Lansek, & Bradshaw, 2005). Internal Versus External Cueing and SpeechEvidence is also emerging regarding the influence of internal versus external cueing on speech production. The benefits of external cues have been demonstrated...

“…Complete behavioural and neurochemical sparing is achieved when exercise of the affected limb begins immediately after the lesion, whereas no sparing occurs when exercise begins 7 days after 6-OHDA lesion (Tillerson et al, 2001). Furthermore, the data from animal models might parallel observations of beneficial effects of exercise on motor and non-motor symptoms in PD patients (Lehman et al, 2005; reviewed by Gage and Storey, 2004;Logroscino et al, 2006). In addition, epidemiological studies show a negative correlation between the regular practice of exercise and the prevalence of PD in humans, at least in males (Tsai et al, 2002;Chen et al, 2005a).…”

Training with Verbal Instructional Cues Results in Near-term Improvement of Gait in People with Parkinson Disease

Abstract: The instructional set was effective in improving parameters of gait for at least 4 weeks. These data support the concept that people with Parkinson disease have a potential for motor learning.
