Changes in Autonomic Nervous System and Axillary Temperature Caused by Electric Potential Therapy
Summary
Electric potential therapy may alter the autonomic nervous system, as indicated by changes in saliva cortisol levels and a rise in axillary temperature. Further research is needed to clarify these physiological effects.
Area of Science:
- Physiology
- Biomedical Engineering
Background:
- Autonomic nervous system (ANS) regulation is crucial for maintaining homeostasis.
- Electric potential therapy (EPT) is an emerging modality with potential physiological effects.
- Understanding EPT's impact on the ANS and thermoregulation is important for its clinical application.
Purpose of the Study:
- To investigate the effects of electric potential therapy on the autonomic nervous system (ANS) and axillary temperature.
- To analyze changes in heart rate variability (RR intervals) and salivary cortisol as indicators of ANS activity.
- To assess the impact of EPT on peripheral body temperature.
Main Methods:
- Two experiments were conducted to evaluate EPT's physiological effects.
- Autonomic nervous system function was assessed via frequency analysis of successive heartbeats (RR intervals) and salivary cortisol measurements.
- Axillary temperature was monitored to evaluate thermoregulation changes.
Main Results:
- No significant changes were observed in RR intervals, suggesting limited impact on heart rate variability.
- Salivary cortisol levels indicated a change in the autonomic nervous system during EPT.
- A significant increase in axillary temperature was recorded, suggesting a thermoregulatory response.
Conclusions:
- Electric potential therapy may influence the autonomic nervous system, evidenced by salivary cortisol changes, though RR interval analysis was inconclusive.
- EPT appears to induce a significant increase in axillary temperature.
- The observed inconsistencies in ANS indicators warrant further investigation and discussion of future research directions.

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

33.3K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:29Decreased Body Temperature
861
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

01:18Disorders of the Autonomic Nervous System
1.2K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
