Thermosensation

Thermosensation

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...

Decreased Body Temperature

Decreased Body Temperature

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 sustained extreme cold exposure, and severe...

Summary

Spinal manipulative therapy at L5 caused localized warming on the treatment side. These cutaneous temperature changes suggest a physiological response to the manipulation, though mechanisms require further study.

Background:

Low back pain is a prevalent condition impacting millions globally.
Spinal manipulative therapy (SMT) is a common treatment for low back pain.
Understanding the physiological effects of SMT is crucial for optimizing treatment efficacy.

Purpose of the Study:

To investigate localized paraspinal cutaneous temperature (CT) changes following SMT at the L5 vertebral level.
To compare temperature modifications between a treatment group receiving SMT and a sham group.

Main Methods:

Twenty subjects with acute low back symptoms were randomized into treatment (n=10) or sham (n=10) groups.
Infrared cameras measured bilateral paraspinal CT at L5 before and at multiple time points after intervention.
The treatment group received a lumbar roll technique with thrust; the sham group received the same technique without thrust.

Main Results:

The treatment group exhibited a 0.2°F warming on the ipsilateral side immediately post-intervention (t(0)).
By 3 minutes post-intervention (t(3)), the ipsilateral side warmed by approximately 0.6°F, while the contralateral side cooled.
Significant differences in CT were observed between sides and over time in the treatment group (P=.002 and P=.016, respectively).

Conclusions:

SMT at L5 appears to induce measurable changes in paraspinal CT.
These CT modifications suggest a potential physiological response to spinal manipulation.
The precise meaning and underlying mechanisms of these observed temperature changes warrant further investigation.
