Summary
Palatographic imaging offers insights into tongue movements during speech, aiding in diagnosis. However, further high-quality studies are needed to confirm its clinical diagnostic and therapeutic value.
Area of Science:
- Speech Science
- Medical Imaging
- Diagnostic Tools
Background:
- Assessing tongue articulation during speech is challenging due to oral cavity inaccessibility.
- Understanding tongue position is crucial for fundamental research and medical diagnoses of speech disorders.
- Palatographic imaging methods offer potential for visualizing articulatory sequences and identifying pathological mechanisms.
Purpose of the Study:
- To review various palatographic procedures.
- To evaluate the eligibility of palatographic methods as diagnostic tools for speech disorders.
Main Methods:
- A selective literature search was conducted across multiple databases including Medline-PubMed, Cochrane Reviews, and clinical trial registries.
- The search focused on identifying studies related to palatographic imaging methods and their diagnostic or therapeutic applications.
Main Results:
- A total of 42 descriptive studies were identified.
- No prospective randomized studies evaluating the diagnostic or therapeutic value of palatographic imaging were found.
Conclusions:
- Palatographic procedures can reveal non-visible articulatory movements.
- The impact of examination procedures on natural articulation requires further investigation.
- High-evidence studies are needed to establish the sensitivity, specificity, effectiveness, and efficiency of palatography for diagnosis and therapy.

01:12Voltammetric Techniques: Linear-Scan (E vs Time)
Polarography is a classical voltammetric technique used to analyze electrochemical reactions. This method applies a linear potential sweep to a dropping mercury electrode (DME), and the resulting current is measured. A dropping mercury electrode is commonly used as the working electrode in polarography. It consists of a capillary tube filled with mercury, where the tiny droplet forms at the tip. This droplet continuously drops from the capillary, creating a new electrode surface for each...
03:09Measuring Reaction Rates
Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical field in...
01:17Controlled-Potential Coulometry: Electrolytic Methods
Controlled-potential coulometry, also known as potentiostatic coulometry, employs a three-electrode system in which the working electrode's potential is precisely regulated using a potentiostat. Platinum working electrodes are utilized for positive potentials, while mercury pool electrodes are favored for extremely negative potentials. The platinum counter electrode is separated from the analyte using a membrane or salt bridge to avoid interference in the analysis.

01:17Voltammetric Techniques: Pulse Voltammetry
Differential-pulse voltammetry (DPV) is a type of voltammetry that involves applying a series of voltage pulses to an electrochemical cell while measuring the resulting current. In DPV, the differential pulse or small potential pulses are superimposed on a linear potential sweep. The magnitude of these pulses is typically small, often in the millivolt range. Each voltage pulse lasts a short duration, usually in the order of a few milliseconds, and is applied at regular intervals along the...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

01:20Voltammetry: Overview
Voltammetry is an electroanalytical technique in which the current flowing through an electrochemical cell is measured as a function of applied potential, typically under conditions of concentration polarization. The technique provides valuable information about redox-active species, and the current response is plotted as a voltammogram.
