Thermal imaging becoming more popular in medicine and also in sports. The technique may
be helpful as an additional method in standard training protocol because of its non-invasive
and safe properties.
The aim of study was to perform the thermal analysis of endurance sportsman during training
cycle and sports clothes temperature parameters evaluation. An attempt was made to evaluate
the metabolic rate and thermoregulation mechanisms of athlete’s organisms based on obtained
thermal parameters. The data was used also for temperature changes analyse in case of body
efficiency rating and for the thermal comfort evaluation in the sports thermo-active clothing.
Some dependences between training level and the body temperature stability were showed,
which seems to confirm the thesis of adaptation processes in athlete’s body. Moreover, the
obtained correlations between standard body’s efficiency and thermal parameters show high
convergence and statistical significance, which may indicate the possibility of using thermal
imaging as a training plan support method.
The thermoactive clothes thermal analysis seems to be helpful for selection and evaluation the
training wear, which will be adapted to training conditions and support the body
thermoregulation natural mechanisms and overheating protection
Can we use thermal imaging to evaluate the effects of carpal tunnel syndrome surgical decompression?
Research is intended to verify if thermal imaging can be used in diagnosing and monitoring the carpal tunnel syndrome (CTS). This disease is not easy to diagnose using traditional methods. Also, the difficulties in monitoring carpal tunnel surgery effects necessitate new, noninvasive method, which gives more information. The research group consists of 15 patients with CTS and control group of healthy people. All patients who were examined before surgery were also tested 4 weeks after surgery, to check the effects of treatment. In addition a lot of our patients had or will have open carpel tunnel release surgery. Diagnosis of CTS was performed by thermal imaging in both hands from phalanges to the area of the wrist on the external and palmar side of the palm. Using infrared (IR) camera one can observe high temperature gradient on hand-tested areas and these differences prove the diagnosis. Moreover patients after surgery have better temperature distribution and it was closer to control group. Results prove that surgery is the best, and currently, the only method to treat CTS. Thermal imaging may be helpful in diagnosing CTS
Myofascial Trigger Points Therapy Modifies Thermal Map of Gluteal Region
Background. (ermal imaging may be effectively used in musculoskeletal system diagnostics and therapy evaluation; thus, it may be successfully applied in myofascial trigger points assessment. Objective. Investigation of thermal pattern changes after myofascial trigger points progressive compression therapy in healthy males and females. Methods. (e study included 30 healthy people (15 females and 15 males) with age range 19–34 years (mean age: 23.1 ± 4.21). (ermograms of myofascial trigger points were taken pre- and posttherapy and consecutively in the 15th and 30th minutes. Pain reproducible by palpation intensity was assessed with numeric rating scale. Results. Progressive compression therapy leads to myofascial trigger points temperature
(p 0.02) and surface (p 0.01) in males. In females no statistically significant changes were observed. Manual treatment leads to a decrease in intensity of pain reproducible by palpation in males (p 0.03) and females (p 0.048). Conclusions. (e study indicates that myofascial trigger points reaction to applied therapy spreads in time and space and depends on participants’ sex
The applications of infrared thermography in surgical removal of retained teeth effects assessment
during filling cavities, laser treatment and inflammation of periodontal tissues. The biggest problem in thermal imaging was
limiting access and rapid change of humidity when the mouth opens during measurements. However, nowadays thermal map
of body surface is correlated with inflammatory state changing inner mouth. The aim of this study was to assess the suitability
of thermal imaging to localize the inflammation and monitor treatment effects after surgical removal of third retained
molar teeth. The cohort consisted of 27 patients with referral for the surgical extraction of the third retained molar. Thermal
imaging of the sagittal face was performed before and after the procedure and on the first, fourth and seventh day after the
extraction. Obtained thermal maps are correlated with the third molar teeth inflammation location. Moreover, the changes
of temperature in the area of both the tooth and the cheek correspond to the mechanisms of wound healing described in the
literature. Obtained results were not only qualitative but also quantitative what was confirmed by statistically significant
difference. It seems that thermal imaging, which is a noninvasive method, can be used to monitor treatment processes after
surgical procedures, as well as on the location of inflammation
Usefulness in developing an optimal training program and distinguishing between performance levels of the athlete’s body by using of thermal imaging
The goal of the training is to enable the body to perform prolonged physical e ort without
reducing its e ectiveness while maintaining the body’s homeostasis. Homeostasis is the ability of the
system to maintain, in dynamic balance, the stability of the internal environment. Equally as important
as monitoring the body’s thermoregulation phenomena during exercise seems to be the evaluation of
these mechanisms after physical e ort, when the athlete’s body returns to physiological homeostasis.
Restoring homeostasis is an important factor in body regeneration and has a significant impact on
preventing overtraining. In this work we present a training protocol using a rowing ergometer,
which was planned to be carried out in a short time and which involves working the majority of the
athlete’s muscles, allowing a full assessment of the body’s thermal parameters after stopping exercise
and during the body’s return to thermal equilibrium and homeostasis. The significant di erences
between normalized mean body surface temperature obtained for the cyclist before the training period
and strength group as well as before and 10 min after training were obtained. Such observation
seems to bring indirectly some information about the sportsperson’s e ciency due to di erences
in body temperature in the first 10 min of training when sweat does not play a main role in surface
temperature. Nearly 1 C drop of mean body temperature has been measured due to the period
of training. It is concluded that thermovision not only allows you to monitor changes in body
temperature due to sports activity, but also allows you to determine which of the athletes has a high
level of body e ciency. The average maximum body temperature of such an athlete is higher (32.5 C)
than that of an athlete who has not trained regularly (30.9 C) and whose body probably requires
further training
May thermal imaging be useful in the assessment of dentalanaesthesia? : preliminary study
The main goal of this study was to find out if thermal imaging may be useful in the evaluation of two types of anaesthetic injections-with and without a vasoconstrictor. There were 20 patients (13 women and 7 men) involved in the study. The group was divided into two subgroups. Patients from the first subgroup received infiltration anaesthesia (so-called: IA) of lidocaine (2 mL) and the second group included patients, who received infiltration anaesthesia (so-called: IAN) of lidocaine with 2% noradrenaline (2 mL). The obtained results showed a significant increase in the average temperature 10 min after the injection. In the IA group, the temperature increase was nearly 1.0 °C what was 0.3 °C higher than in the IAN group. Moreover, temperature changes showed a wide plateau between 10 and 25 min after anesthesia administration. The effect of temperature rise was also observed on the contralateral cheek where there was no intervention renders by a contralateral reflex
Thermal effects of topical hyperbaric oxygen therapy in hard-to-heal wounds - a pilot study
Clinical studies have been performed to evaluate the thermal response of topical hyperbaric
oxygen therapy (THBOT) in patients suffering from hard-to-heal wounds diagnosed as venous leg
ulcers located on their lower extremities. It was found that this therapy leads to a temperature
decrease in areas around the wound. Moreover, a minor temperature differentiation between all
areas was seen in the third period of topical hyperbaric oxygen therapy (THBOT) that may suggest
that microcirculation and thermoregulation improvement start the healing process. On the other
hand, the results of the conducted studies seem to prove that thermal imaging may provide a safe
and effective method of analyzing wound healing of hard-to-heal wounds being treated with THBOT.
This is the first study that tries to show the possibilities of a very new method by evaluating treatment
of hard-to-heal wounds using thermal imaging, similar to the hyperbaric oxygen therapy effects
evaluated by thermal imaging and described previously. However, the first clinical results showed a
decrease in temperature due to the THBOT session and some qualitative similarities in the decrease
in temperature differentiation between the studied areas and the temperature effects obtained due to
hyperbaric oxygen therapy
A quantitative thermal analysis of cyclists’ thermo-active base layers
It is well known that clothes used in sporting activity are a barrier for heat exchange between the environment and athlete,
which should help in thermoregulation improvement. However, it is difficult to evaluate which top is best for each athlete
according to the characteristics of the sport. Researchers have tried to measure the athlete’s temperature distribution during
exercise at the base layers of tops with different approaches. The aim of this case study was to investigate the use of
thermography for thermo-active base layer evaluation. Six new base layers were measured on one cyclist volunteer during
a progressive training on a cycloergometer. As a control condition, the skin temperature of the same volunteer was
registered without any layer with the same training. A training protocol was selected approximate to cycling race, which
started from the warm-up stage, next the progressive effort until the race finished and at the end ‘‘cool-down’’ stage was
over. In order to show which layer provided the strongest and weakest barrier for heat exchange in comparison with
environment, the temperature parameters were taken into consideration. The most important parameter in the studies was
the temperature difference between the body and the layers, which was changing during the test time. The studies showed a
correlation between the ergometer power parameter and the body temperature changes, which has a strong and significant
value. Moreover, the mass of every layer was checked before and after the training to evaluate the mass of the sweat
exuded during the test. From this data, the layer mass difference parameter was calculated and taken into consideration as a
parameter, which may correspond with the mean heart rate value from each training. A high and positive correlation
coefficient was obtained between the average heart rate and the mass difference for the base layers. Thermal analysis seems
to have a new potential application in the objective assessment of sports clothing and may help in choosing the proper
clothes, which could support heat transfer during exercising and protect the body from overheating
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
