Abstract

Purpose:

To quantify variability in external stuttering and other stuttering symptoms and reactions within adults who stutter (AWS) across three fluency states.

Method:

A total of 130 AWS responded to an online survey that first asked them to rate their external stuttering severity when least fluent (LF), most naturally fluent (MNF), and when using fluency shaping (FS) techniques using a 9-point semantic differential scale. Fourteen subsequent questions probed a wide range of stuttering symptoms and listener reactions in reference to each of the three states.

Results:

High intra- and interindividual variability was observed across all items probed. Within AWS, for 13 of 14 symptoms and reactions, LF was associated with the most negative ratings and MNF with the most positive ratings. FS ratings consistently fell between LF and MNF. Importantly, many symptoms continued to be prominently displayed even in the MNF state.

Conclusions:

Findings provide a unique view of intra-individual variability in stuttering symptoms in reference to external stuttering severity. In addition, these data highlight the costs and benefits associated with using FS. Other clinical implications are discussed.

Variability: Analysis

Variability: Analysis

Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

Asthma-III: Symptoms and Complications

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Factors Affecting Illness

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:

Factors Affecting Pulmonary Ventilation

Factors Affecting Pulmonary Ventilation

Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
