Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms. Hand washing...

Utility of Dissociated Intrinsic Hand Muscle Atrophy in the Diagnosis of Amyotrophic Lateral Sclerosis

Dissociated atrophy of intrinsic hand muscles, termed the split hand, appears to be a specific feature of amyotrophic lateral sclerosis (ALS). Consequently, a novel neurodiagnostic test, termed the split hand index, was developed to quantify the clinical phenomenon of the split hand, which differentiated ALS from mimic disorders.

Wrist and Hand Examination

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The wrist is a complex joint made up of 8 carpal bones and their numerous articulations and ligaments. Overlying the wrist are the tendons and muscles of the hand and fingers. The hand is made up of 5 metacarpal bones, and the tendons that run to the hand overlie these bones. Finally, the fingers consist of 14 phalanges with their articulations held together by collateral ligaments and volar plates. Common mechanisms of...
FAQs
Autonomic regulation changes skin blood flow through vasoconstriction and vasodilation. Vasoconstriction alters the amount of warm blood reaching the skin, while vasodilation changes surface heat distribution. Measuring the resulting temperature difference provides a noninvasive view of peripheral physiological regulation, rather than a direct measure of behavior itself.
Comparing both hands or distinct hand regions allows researchers to examine differences in how heat is distributed across the body’s surface. This comparison can help characterize peripheral physiological variation associated with autonomic regulation. It also provides more specific information than treating hand temperature as a single, uniform value.
Stress, emotional arousal, attention, and changing environmental conditions can all be relevant contexts for examining differential hand temperature. These conditions may alter autonomic regulation and, consequently, skin blood flow and heat distribution. Researchers can therefore compare temperature patterns with the behavioral situation being studied to investigate physiological responses across experimental settings.
Researchers measure temperatures from both hands or from selected hand regions, then examine the difference between those measurements. The temperature data can be considered alongside observed behavior and other physiological signals. This workflow links peripheral physiological changes with events or responses recorded during the experimental setting without relying on a single type of observation.
The measure can indicate changes in peripheral physiological state that occur alongside stress, emotional arousal, attention, or environmental change. It does not independently identify a specific behavior or emotional state. Its value comes from relating temperature differences to observed behavior and other physiological signals, which supports interpretation of autonomic responses in context.
Behavioral researchers can use this noninvasive measure to study how autonomic regulation relates to human behavior. Comparing temperature responses across experimental settings may help describe individual physiological responses to stress, attention, emotional arousal, or environmental conditions. When combined with behavioral observations and other signals, it contributes physiological context to behavioral findings.
