“…Millard et al [4] (2008) reported that 4 out of 6 children in their study (60%) were “cured” and discharged through indirect PCIT. The consistency of the results of this study with the previous studies supports more powerfully the use of indirect treatment programs for these groups of children [52, 53]. …”

Purpose: The present study explored the effectiveness of the Lidcombe Program, the parent-child interaction therapy (PCIT) approach, and an integrated (Lid-PCIT) program on the treatment of children who stutter. Methods: The present research was a single-subject study with an alternative treatment design. Participants were 6 preschool children who were randomly assigned into three groups. Each group received the entire indirect (PCIT), direct (Lidcombe), or integrated (Lid-PCIT) program and were assessed through severity rating (SR), and percent stuttered syllables (%SS), and video analysis. Results: For all children the SR and the %SS were reduced but the percentage of non-overlapping data of the three interventions showed that it was reduced more in the Lidcombe and in the Lid-PCIT programs. Conclusions: This study provided preliminary evidence that Lidcombe, PCIT, and integrated programs were effective in reducing the SR and the %SS in preschool children who stutter. These results are potentially important as both indirect and direct interventions in the primary years can help children who stutter to overcome their disorder.

“…Therefore, corroboration with a larger sample size via direct replication is warranted [14]. Replication provides two basic functions essential for the substantive base of any scholarly field: verification and disconfirmation, i.e., a fact is not a fact until it is replicable [14]. Specific to the current issue, a causal relationship exists when a tracheotomy is a sufficient condition for the occurrence of aspiration.…”

Confirmation of No Causal Relationship Between Tracheotomy and Aspiration Status: A Direct Replication Study

Debate continues regarding an association between tracheotomy and aspiration status. The aim of this research was to perform a direct replication study to investigate further the causal relationship, if any, between tracheotomy and aspiration. Twenty-five consecutive adult hospitalized patients participated. Inclusion criteria were a pretracheotomy dysphagia evaluation, subsequent tracheotomy and tracheotomy tube placement, then a post-tracheotomy dysphagia reevaluation prior to decannulation. Twenty-two (88%) participants exhibited the same aspiration status or resolved aspiration pre- versus post-tracheotomy. Three participants exhibited new aspiration post-tracheotomy due to worsening medical conditions. Conversely, four participants exhibited resolved aspiration post-tracheotomy due to improved medical conditions. Excluding these seven participants, all nine participants who aspirated pretracheotomy also aspirated post-tracheotomy and all nine participants who did not aspirate pretracheotomy also did not aspirate post-tracheotomy (P > 0.05). No statistically significant differences were found between aspiration status and days since tracheotomy (chi (2) = 0.08, P > 0.05) or between age and aspiration status (P > 0.05). The absence of a causal relationship between tracheotomy and aspiration status was confirmed.

“…The purpose of this systematic replication study [19], i.e., replication of a study with minimal variations in design, was to determine if a clinical swallowing examination consisting of six identi®ers of aspiration risk, i.e., dysphonia, dysarthria, abnormal gag re¯ex, abnormal volitional cough, cough after swallow, and voice change after swallow [12], would have acceptably high risk assessment values to predict aspiration risk in the acute stroke population when compared with an instrumental ®beroptic endoscopic evaluation of swallowing (FEES) [20,21].…”

Aspiration Risk After Acute Stroke: Comparison of Clinical Examination and Fiberoptic Endoscopic Evaluation of Swallowing

Aspiration is an important variable related to increased morbidity, mortality, and cost of care for acute stroke patients. This prospective systematic replication study compared a clinical swallowing examination consisting of six clinical identifiers of aspiration risk, i.e., dysphonia, dysarthria, abnormal gag reflex, abnormal volitional cough, cough after swallow, and voice change after swallow, with an instrumental fiberoptic endoscopic evaluation of swallowing (FEES) to determine reliability in identifying aspiration risk following acute stroke. A referred consecutive sample of 49 first-time stroke patients was evaluated within 24 hours poststroke, first with the clinical examination followed immediately by FEES. The endoscopist was blinded to results of clinical testing. The clinical examination correctly identified 19 subjects with aspiration risk, when compared with the criterion standard FEES, but incorrectly identified 3 patients as having no aspiration risk when they did. The clinical examination incorrectly identified 19 subjects with aspiration risk but determined correctly no aspiration risk in 8 patients who did not exhibit aspiration risk on FEES. Clinical examination sensitivity = 86%; specificity = 30%; false negative rate = 14%; false positive rate = 70%; positive predictive value = 50%; and negative predictive value = 73%. It was concluded that the clinical examination, when compared with FEES, underestimated aspiration risk in patients with aspiration risk and overestimated aspiration risk in patients who did not exhibit aspiration risk. Careful consideration of the limitations of clinical testing leads us to believe that a reliable, timely, and cost-effective instrumental swallow evaluation should be available for the majority of patients following acute stroke.
