“…Several studies have used thermography in diagnostic cases of neoplasias [18], muscle damage [19, 20], ischemia in diabetes [21], and evaluation and recovery of muscle function [17]. However, few studies have used this tool in the field of neurology and future research is suggested.…”

Background: Stroke rehabilitation that is based on the patients’ needs, experiences, and priorities requires extensive knowledge and skills to capture and integrate the perspectives of the subject. Purpose: The objective of this study was to evaluate the acute effect of an occupational therapy protocol associated with virtual reality (VR) on the symmetry of body temperature (BTP), balance, and functionality of patients with stroke sequelae. Methods: Ten patients (69.84 ± 7.55 years) diagnosed with stroke between 2 and 10 years earlier were evaluated during clinical care sessions integrated with VR games. Associated with games, all patients were stimulated to use both upper and lower limbs and distribute body weight symmetrically, and perceptual stimuli of body-half training, alignment, postural control, and balance were given. The variables of thermography (temperature [°C] and body asymmetry) of the upper and lower limbs, balance (Berg scale), and functionality were analyzed before and after the test. Results: BTP was reduced in the 4 upper and lower limb body regions of interest: the right arm (p = 0.024, Cohen’s d = 1.02), previous direct hand (p = 0.034, Cohen’s d = 1.22), right back hand (p = 0.003, Cohen’s d = 1.85) and Left (p = 0.013, Cohen’s d = 0.92), right thigh (p = 0.035, Cohen’s d = 1.32), and left thigh (p = 0.047, Cohen’s d = 0.92). The mean of the bilateral asymmetry variation of the arm in the anterior position at the pre test was classified according to the level of attention monitoring (which means that the asymmetry rate is above normal), changing its state at the end of the intervention to normal. There was an increase in the functional independence score (p = 0.015, Cohen’s d = 0.50) and in the static and dynamic balance function (p = 0.001, Cohen’s d = 0.07). Conclusion: VR associated with occupational therapeutic planning can amplify and potentiate neurological recovery following stroke.

“…The cellular infiltrations with an extensive vascular component (vasodilatation, edema exudation) are responsible for an increase in the heat generation at the injection site that can be measured by an IR camera [10]. Changes from 0.2 to 2 • C have been demonstrated in inflammatory dermatologic processes [20,[24][25][26].…”

Setting: The infection with Mycobacterium tuberculosis gives a delayed immune response, measured by the tuberculine skin test. We present a new technique for evaluation based on automatic detection and measurement of skin infrared emission. Design: 21 subjects (57.0±17.8 yr), (7/14, M/F) with suspected tuberculosis contact were examined with an IR thermal camera, 48 hours after skin injection. Results: In 15 subjects, IR analysis was positive for tuberculine test. Mean temperature of injection area was higher, around 1 ºC, for the positive group (36.0± 0.3 ºC positive group; 35.2±1.7 ºC negative group, p<0.001, Non parametric U Mann-Whitney Test). Conclusion: IR may represent an improved estimation of tuberculosis infection, given that it does not depend on reader variability and measures the increase of heat irradiation produced by the allergic tuberculine response.

IntroductionInfrared thermal imaging is based on perfusion changes reflected by skin temperature variations. It is an established non-invasive diagnostic method within vascular surgery, with applications such as peripheral arterial disease assessment and prevention of diabetic foot complications. However, owing to hardware limitations or lack of resources, it is not yet widely used in clinical practice.ReportA novel portable infrared imaging camera, easily powered via a smartphone and free App software, was used to obtain digital thermograms during the clinical evaluation of acute limb ischaemia (ALI).DiscussionPortable infrared imaging represents a new promising tool for the assessment of tissue perfusion that can be applied at the bedside during clinical evaluation of suspected ALI.
