OBJECTIVIZATION OF THE EFFECT OF A COMPLEX OF PHYSICAL FACTORS IN PATIENTS WITH CARPAL TUNNEL SYNDROME BY ELECTROMYOGRAM TEST

CTS is the most common compression neuropathy with an incidence of 125-515/100 000. It is a result of compression of the median nerve by the transverse carpal ligament. It is observed in 2 to 5% of the general population, more frequently in women.Electromyography is considered the most accurate diagnostic procedure, although it cannot be fully accepted as a gold standard due to the possibility of false positives (about 15%) and false negatives (about 18%) [1]However, because of its low cost, in comparison to other diagnostic methods, its high diagnostic reliability, and the few contraindications to its application, it remains a method of choice for diagnosis and follow-up of the reinnervation of the median nerve in CTS patients.Aim of study. To investigate the effect of a complex of physical factors on the reverse development of symptoms of moderate carpal tunnel syndrome using electromyography.Materials and methods. 57 patients with mild to moderate degree of carpal tunnel syndrome clinically proven by electroneurographic study were еexamined. 38.60% of the patients were with right hand affected, 9 patients (15.80%) with left hand affected and 26 patients (45.60%) with bilateral involvement (n=26). In the last group, we examined both hands, ie 57 patients and 82 hands were investigated.Based on the analysis of our own studies, we applied the following complex physiotherapeutic program to the patients involved in the study: ultrasound, electrophoresis with Nivalin (Galantamine), and traditional kinesitherapy program.In our study, we examined the sensory and motor fibres of the n. medianus. Changes in distal latency, amplitude, and conduction velocity were observed.Results and discussion. The electroneurographic examination we performed showed a statistically significant change (p <0.001) in the normalization of distal latency, conduction velocity and M amplitude in both the sensory and motor fibres of the affected nerve. These results were reported between the first and fourth months after physiotherapy. There is also a tendency for their retention within the next 4-8 months.Correlation analysis shows that there is a very strong, statistically significant (p <0.001) relationship between the ENG parameters for n. medianus sensory and motor fibres conductivity (distant latency, SNAP and conduction velocity) and the treatment performed, which is established even at the first check-up (1-4 months) after end of the treatment, and the results achieved are maintained over time.The statistically significant changes in the values of ENG parametric fibers of n. medianus, we refer to the complex physiotherapy treatment, aimed at improving the trophic and nerve conduction, accelerating the regenerative processes of the nerve structures, improving the trophic and vascularizing the structures located in the carpal tunnel.Last but not least, the fibrolytic action of ultrasound therapy leading to the spreading of fibrous seals, which is quite common in CTS, is also important. Although different in their mechanism of action, the physiotherapeutic procedures included in our program have a synergistic effect aimed at overcoming the functional deficiency and reversing the symptoms of CTS.Conclusions. Our study on the effectiveness of a complex of physical factors in the conservative treatment of the CTS showed that early diagnosis and timely initiation of physiotherapeutic treatment are a prerequisite for achieving very good results in terms of functional recovery of the affected hand and the reverse development of clinical symptoms in patients with proven mild to moderate CTS.The segmental demyelination of the sensory and motor fibers of n. medianus in the initial stages, as a result of its compression in the area of the carpal canal, is a reversible process. An integrated approach to the treatment of CTS, including early diagnosis, prevention and treatment, is the key for success in mild and moderate forms of the syndrome, and competent and timely medical advice is often crucial.CTS is the most common compression neuropathy with an incidence of 125-515/100 000.

Wellness syndrome

Introduction: Wellness is a lifestyle choice based on the holistic approach to health. In this century, and during the last decade in particular, wellness centers and wellness procedures have become quite popular. And just like any trend, the one related to wellness may lead to extremes. In this specific case, the extremes are defined as a „wellness syndrome“ – an obsession with a healthy lifestyle. The maximization of the efforts to achieve wellness can turn against us and make us feel bad making us isolate ourselves from the rest. The wellness syndrome leads to a search for the perfect diet, turns us into corporate athletes, chasing our own selves and monitoring each aspect of our everyday life. This is a world where feeling well is indistinguishable from being well. Aim: This article is an attempt to separate the aspiration toward wellness from the other extreme – an obsession with psycho-emotional techniques of mastering stress or a fixation with different esthetic procedures (which, in addition to the beneficial desired effect, may have side effects, if overused). One such condition distances the individuals from the real world and society, limits them to a tiny circle of other people, which automatically impairs at least one aspect of their wellness – the social one. Materials and Methods: Articles and scientific publications related to the topic were searched in the PubMed database and Google Scholar. Articles published in the last decade were included in the review. The search was conducted with a list of keywords used also in different combinations. These were: “health”, “wellness”, “wellness syndrome”, “orthorexia”, “wellbeing”, „esthetics“. The article draws on the work by Carl Cederström and André Spicer titled „Wellness Syndrome“, which currently provides the most detailed information on the “wellness syndrome”.Special attention is paid to orthorexia as one of the most common cases of overstepping the border between a healthy diet and the maniacal obsessive idea of consuming healthy food, which may develop into a disease process.Conclusion: The basic knowledge and skills by which physical therapists should encourage health and wellness in their patients and clients are a topic included in university curricula. However, the provided information is predominantly theoretical. The increased attention to applying theory and the development of clinical competence into skills, such as consultation, change in healthy behavior and motivation (e.g. physical activity, diet and maintaining normal weight, smoking cessation, sleep hygiene, and stress management), will improve the ability of physiotherapists to include adequate models of improving the health and wellness of their patients and clients

Halotherapy - an alternative method for the treatment of respiratory diseases

Halotherapy is an alternative method of treating respiratory diseases. This kind of treatment has become more and more popular in last decades. Sodium chloride has a proven an­tibacterial, antimycotic and anti-inflammatory effect and is of great importance for the normal function of the bronchial ciliated epithelium. This article reveals the benefits of salt in regard to the respiratory system, indications and contrain­dications for this kind of treatment and the possibilities for combining it with some other physical therapy methods

Mineral water from spring Px-6 - physico-chemical characteristics and indications for use

The aim of the article is to present full physiochemical analyses of the mineral water from spring Px-6 which is used for the treament of patients in the Clinic of Thalassotherapy, Physiotherapy and Rehabilitation at Saints Constantine and Helena resort, the indications for use of that water and the main benefits that may occur after treatment.Full physico-chemical analyses show significant stability in the composition of the components. Combining physical exercises, electrotherapy, hot packs with lye or other kind of physical factors with balneotherapy is highly effective for the treatment of different disorders. The use of water for prophylaxis, wellness and recreation in healthy people is not excluded. Contraindications are limited.Though the positive effect of water from spring Px-6 is proven concerning its physico-chemical characteristics and our own experience, more scientific researches should be conducted to increase the evidence of the benefits of this water and its further optimal use for prophylaxis, treatment and wellness
