Kinesitherapeutic Approach towards Pectus Carinatum Deformity: A Clinical Case

Introduction: A protruding chest is an overgrowth of the rib cartilage that causes protrusion of the sternum due to rapid growth during puberty, vitamin D deficiency, hereditary transmission, and others. The deformity "pectus carinatum" can be classified as chondrogladiolar or chondromanubrial, depending on the place of greatest protrusion, and lateral deformations are possible. Treatment is usually performed conservatively by corset reinforcement, but in very rare cases, surgery is required. Kinesitherapy is widely used in pectus carinatum; it combines a variety of exercises and techniques that further enhance the effect of treatment.The aim of the article is to observe the effectiveness of an individually appointed kinesitherapy program for a patient with pectus carinatum.Material and Methods: A case of a 13-year-old girl with complaints of chest and back pain is being considered. After consultation with an orthopedist, a deformity of the sternum was found, with a stronger protrusion of the right thoracic half against the background of mild S-shaped thoracolumbar scoliosis. Conservative treatment was prescribed, including exercise therapy for the spine, swimming, a dorsal corset, and a compression corset. The patient was referred to the University Center of Oriental Medicine of MU-Varna (UCOM) for the implementation of an individual rehabilitation treatment plan. A set of exercises was applied every other day for 1 month, after which the patient continued to perform them independently. After the treatment, she was recommended a visit to UCOM twice a month in order to monitor the results achieved and adapt the program to her specific condition.Results: Based on the applied plan, the following results have been achieved: an improvement in posture, muscle strengthening, and overcoming muscle imbalance.Conclusion: The selection of the right methods and materials, their proper application, and implementation, together with constancy and the desire for improvement, lead not only to visible results but also support the overall functioning of the individual

Development of the Transformer for Contactless Power Suppliers

Contactless power supplier is composed of a transformer having the distinct primary and secondary coils separated by air gap. Because of the electromagnetic compatibility problem, it is essential to keep the leakage magnetic fields around the contactless power supplier as low as possible.This paper carries out the wavelets multi-resolution analysis to the magnetic field distributions around contact- less power supplier.　As a result, we have succeeded in obtaining one of the reasonable core shapes by observing the wavelets spectra of measured magnetic field vector distributions. Furthermore, it is revealed that a tested trial transformer gives nearly 80 percent power transmission efficiency even though the primary and secondary coils are separated by 10mm air gap

Magnetic Elastomer Sensor for Dynamic Torque and Speed Measurements

In this paper is proposed a dynamic torque, rotational speed, and shaft position sensor. It is built of magnetic elastomer coating directly applied over a rotating shaft. The sensor is used for precise measurements of changes in torque and speed, and it is usable at high rotational speeds, directly on the device shaft. The sensor is based on magnetic elastomer material deformation and the corresponding change in magnetic field amplitude and direction. The proposed sensor design is simple and can acquire reliable readings for a wide range of rotational speeds. Sensor design consists of the following: magnetic elastomer coating with nanoparticles, in which, elastomer is used for a sensing convertor; magneto-resistive linear field sensor; and microprocessor unit for calibration and control. Numerical and experimental test results are demonstrated and analyzed. Sensor implementation aims to meet magnetic mechatronic systems’ specific requirements

Enhance the sensibility of the film infinite eddy current sensors

Previously, we have succeeded in exploiting a new high sensibility eddy current testing sensor called the infinite (∞) coil. Operating principle of this ∞ coil is that two adjacent coils constructing the north and south poles alternatively set a zero magnetic potential region and keep the same situation when eddy currents are flowing along the paths in parallel to the exciting coils. If the eddy currents could not flow the paths in parallel to the exciting coil on the test specimen, then a zero magnetic potential region between the two exciting coil moves toward the other position. This means that a sensing coil located at a mid position of two exciting coil is possible to detect the disturbed magnetic fields, i.e. the defect in the test specimen could be detected from the sensing coil signal. This paper proposes one of the enhancing methodologies of the infinite coil sensibility. Key idea is that the zero magnetic potential region between the north and south exciting poles of the infinite coil is increased by changing the circular to the semicircular shape of the exciting coils. Numerical as well as experimental results verify the validity of this idea
