Introduction Carpal tunnel syndrome (CTS) is a condition caused by chronic compression of the median nerve. The diagnosis is made mainly on the basis of clinical image and confirmed with electrodiagnostic testing (electromyography and nerve conduction study); however, these methods do not always aid in reaching the diagnosis of CTS. Moreover, they are invasive examinations, unpleasant for the patient and have to be performed by a qualified physician. Aim An evaluation of the usefulness of dynamic thermography in the diagnosis of CTS. Material and methods Forty patients were included in the study group. CTS was diagnosed based on clinical examination and electromyography. Forty healthy volunteers were included in the control group. Each of the participants was examined thrice with dynamic thermography. The patient’s hands were first cooled down and then a thermal camera measured their return to normal temperature. The measurement was repeated on the dorsal and volar aspects of each hand. Results The results obtained in the study show that a relief of symptoms after carpal tunnel release does not correlate with thermal image. Moreover, the return to normal hand temperature was faster in the control group. In patients with unilateral CTS, no difference was observed in thermographic images of the affected and healthy hands. Conclusions Dynamic thermography can be useful in confirming CTS diagnosis. Dynamic thermography does not allow for objective assessment of patient’s complaints in the postoperative period. This method has currently limited clinical application. Due to complexity, it presently serves mainly scientific purposes.

“…Quantitative ultrasonography assessment of CTS diagnosis was used in patients with negative electrodiagnostic test findings, especially in the early stage of CTS [21]. The alternative technique proposed is more sensitive and simpler than conventional techniques for detecting CTS, and should be incorporated into thermography [22] and computed tomography [23]. However, these methods are not very common and cannot be conclusively substantiated without further study.…”

Objectives: Non-medical hospital staff members are in frequent contact with patients and therefore are required to perform a wide variety of repetitive and high-frequency activities. The objective of this study was to assess the relationships between upper extremity activity and carpal tunnel syndrome (CTS) among non-medical hospital staff members. Material and Methods: Carpal tunnel syndrome in 144 non-medical hospital staff members was diagnosed using the Nordic Musculoskeletal Questionnaire (NMQ), a physician's diagnosis, physical examination (Tinel's signs and Phalen test) and a nerve conduction velocity (NCV) test. In addition, an ergonomic assessment was performed and a video camera was used to record the physical activities at work. Results: The prevalence rate of CTS was highest for the NMQ (51.9%), followed by physician's diagnosis (49.5% for the right hand, 29.9% for the left hand), physical examination (54.7%), and nerve conduction test (motor nerve 27.5% and 25%, sensory nerve 21.7% and 15%, for right and left hands, respectively). Based on logistic regression models for the NMQ and physician's diagnoses, there was a dose-dependently higher risk of CTS with the upper extremity index among participants, but this was non-significant based on the physical examination and nerve conduction tests. Conclusions: Nerve conduction velocity is the gold standard in diagnosis of CTS, but use of NMQ and physician's diagnosis may overestimate the incidence of CTS in workers who have been engaging in repetitive stress activities for a relatively short time.

“…It is non-invasive, non-radiation, painless and non-contact imaging technique with numerous applications in medicine that include breast diseases (breast cancer), vascular diseases, [ Jesensek Papez B. et al (in 2008 and2009) used a large database of 502 thermal images of the dorsal and palmar side of 132 healthy and 119 pathological hands. It confirmed the hypothesis that the dorsal side of the hand is of greater importance than the palmar side when diagnosing CTS thermographically.…”

Presented paper deals with infrared thermography (IRT) used for the diagnostics of Carpal Tunnel Syndrome (CTS). More studies on medical thermography in the relation with CTS diagnostics were published. Jesensek Papez B. et al. in 2008 and 2009 improved outcome with classification success rates near to or over 80% in dorsal segments of hand. The background of this study is the skin physiological temperature distribution difference on the dorsal hands and pathophysiological temperature distribution on hands with CTS and noninvasiveness and painlessness of IRT. For presented study, the database of 268 thermal images of the dorsal side of 120 healthy (n= 120) and 14 pathological hands (n=14) with clinically diagnosed CTS of 8 patients were examined. We observed the temperature distribution of the whole hand and the partial temperatures of the center point of carpals (D1), the center point of metacarpals (D2) and the finger tips of the third finger from proximal phalanges (D3), the intermediate phalanges (D4) to the distal phalanges (D5) and the Median Nerve Index (MI=(D1-D5)) were calculated.Results obtained from measurements of the five defined points on the dorsal side of hands showed, that the temperature of CTS hands is characterized by a higher temperature in the phalanges unlike the wrist (MI<0, 71,4%), while the temperature is the lowest on distal phalanges (D5) of healthy hands (MI≥0, 85,8%). The results showed that the skin temperatures of median nerve distribution area on dorsal hands were significantly different between CTS and the control group. The sensitivity of IRT in diagnostic process of CTS is 0,714. Results will be confirmed by further screening of statistically significant group of patients.
