Summary
This study found no significant difference in stuttering treatment outcomes between the Westmead Program and the Lidcombe Program for preschool children. High dropout rates suggest tentative conclusions, warranting further research on the Westmead Program.
Area of Science:
- Speech-Language Pathology
- Pediatric Clinical Trials
Background:
- Early stuttering intervention is crucial for long-term outcomes.
- The Lidcombe Program is an established treatment for early stuttering.
- The Westmead Program offers novel treatment approaches for early stuttering.
Purpose of the Study:
- To compare the efficacy of two experimental Westmead Program treatments against the standard Lidcombe Program for early stuttering.
- To evaluate stuttering severity at 9 months post-randomization.
Main Methods:
- A three-arm randomized controlled trial was conducted.
- 91 preschool children diagnosed with early stuttering participated.
- Outcome assessments, including percentage syllables stuttered, were conducted 9 months post-randomization with blinded evaluators.
Main Results:
- No statistically significant difference in percentage syllables stuttered was observed among the three treatment groups at 9 months.
- Substantive dropout rates were noted across all arms.
- Potential factors for dropout included the use of community clinicians, absence of exclusion criteria, and randomization of children under 3 years.
Conclusions:
- Tentative conclusions regarding 9-month stuttering outcomes are advised due to high dropout rates.
- Continued development of the Westmead Program is recommended.
- An internet-based version of the Westmead Program is under development.

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

3.6K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

10.2K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

01:12Trial and Error and Algorithm
403
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

3.1K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
