Summary
Patients experiencing coldness after hemiplegic stroke have significantly lower finger skin temperatures and reduced blood flow in the affected hand. This study clarifies vasomotor changes in hemiplegic arms, identifying key indicators of symptomatic coldness.
Area of Science:
- Neurology
- Vascular Medicine
- Rehabilitation
Background:
- Vasomotor changes in the arm are common after hemiplegic stroke.
- Previous research on hemiplegic arm skin temperature yielded conflicting results.
- Some stroke survivors report distressing coldness in the affected arm.
Purpose of the Study:
- To investigate vasomotor changes in hemiplegic stroke patients experiencing coldness.
- To compare symptomatic and asymptomatic patients regarding temperature and blood flow.
- To understand the severity of coldness as a post-stroke symptom.
Main Methods:
- Recruited patients with symptomatic coldness (n=11) and without (n=10) after hemiplegia.
- Assessed coldness severity via questionnaire compared to other stroke symptoms.
- Utilized thermography for finger skin temperature response to cold stress.
- Measured bilateral hand blood flow using plethysmography.
Main Results:
- Coldness was a highly rated symptom among participants.
- Symptomatic patients showed lower resting finger temperature on the hemiplegic side (P < .0001).
- Reduced finger temperature persisted after cold stress in symptomatic patients.
- Hemiplegic hand blood flow decreased by 35% in symptomatic patients.
Conclusions:
- Hand coldness can be a severe and distressing symptom post-hemiplegic stroke.
- Symptomatic patients exhibit lower finger temperatures and impaired blood flow.
- Findings highlight objective physiological differences in patients with hemiplegic arm coldness.

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
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...
Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
