Avaliação das medidas articulares de membros pélvicos em ovinos

The aim of this study was to determine the angle of motion values for hindlimbs in clinically healthy adult Santa Ines sheep using a standard goniometer. Twenty female Santa Ines sheep weighing 32–45 kg (mean30.4, SD=3.7), and aged from three to six years old were used. A standard transparent plastic goniometer was used to measure passive maximum flexion, maximum extension, and range of motion (ROM) of the shoulder, elbow, carpal, hip, stifle, and tarsal joints, in the right and left limbs. The goniometric measurements were done with the sheep awake and in a standing position. The measurements were made in triplicate by two independent investigators. In all evaluated joints there was no significant difference between the means of both sides. No significant difference was observed between measurements performed by the two investigators. The mean (± SD) values of the measurements (degrees) were: 129 ± 4 (ROM) for tarsal joint; 46 ± 4 (flexion), 146 ± 6 (extension), and 100 ± 4 (ROM) for stifle joint; 54 ± 3 (flexion), 143 ± 7 (extension), and 89 ± 5 (ROM) for hip joint. The data obtained is useful to provide objective information of the joints. More studies are necessary using other breeds

Doenças osteoarticulares em pequenos animais

Osteoarticular diseases are very frequent in small animals, especially dogs. Osteoarthritis is the most common degenerative arthropathy in cats and dogs. It is one of the most important skeletal disease in small animals and it is divided into two broad classes: secondary and genetics. The secondary is originated from situations that can cause joint instability like as trauma, ligament problems and obesity among others. The gene for osteoarthritis comes from hereditary problems such as hip dysplasia, elbow dysplasia and other diseases that can cause articular instability. The hereditary osteoarticular diseases are important only because they can result in the osteoarthritis. It is important to prevent the joint instability and consequently the clinical signs that affect the quality of life of the animals. The most common clinical signs are intermittent claudication, a decrease in performance, reluctance to jump and climb ladders among others. To prevent the clinical signs or mitigate them, the treatments need to be focused on pain control and especially restoration of the affected joint. The treatments most used are the medical and surgery. Anti-inflammatory and analgesics are used in large scale for pain control and to inhibit inflammatory mediators. Furthermore, medical treatment includes weight reduction, physiotherapy and proper nutrition along with anti-inflammatory and analgesics. Surgical treatments are indicated if there is an inadequate response to medical treatment. Physiotherapy is often used in conjunction with other treatments. Besides the reduction of weight is essential and obesity is unacceptable. Cats also suffer from osteoarthritis, but the diagnosis is rarer than in dogs. Usually the cat’s owners relate the reluctance to jump and drop in performance with senility, and when the disease is diagnosed is already in... (Complete abstract click electronic access below)

Variação aguda da frequência cardíaca durante série de hipertrofia para grupo flexor e extensor do cotovelo

Currently individuals are affected by a routine busy and they don't have time for physical activity, highlighting the sedentary lifestyle, a risk factor for cardiovascular diseases. For this reason, it focuses too much on cardiovascular diseases and the importance of physical practice. With the largest divulgation and variety of physical activities, activities that were not as practiced became popular, as is the case of resistive exercise. Much is said of the influence of resistance exercise in physical strength, in muscle development and in the quest for a more defined body. However, studies have shown beneficial contributions of resistance exercise on the cardiovascular system. During the physical effort, some changes occur in the body in order to meet the increased demand for oxygen. Among them is the increase in heart rate (HR), which varies with the intensity of effort. Thus, this research sought to contribute with an analysis of the HR behavior before, during and after 3 sets of hypertrophy, as far for the flexor group of the elbow as to the extensor group. It was observed that, although the HR has increased in the course of the series, the variations of HR were not significant between the flexor group and extensor group of the elbow joint. Also were not significant the differences between the variations of the HR from the 1ª to the 2ª series between the flexor group and extensor group, as well as to the variations from the 2ª to the 3ª series

Avaliação do perfil antropométrico e de força de jovens jogadores de polo-aquático

The present study aimed to analyze the performance of 'boost' among water polo athletes. Twelve athletes (13,9  1,08 years, 169,0  6,0 cm and 59,5  13,5 kg of bodyweight) were under went to anthropometric assessment, body composition and maximum concentric strength of lower limbs. The jump test in the water was done by 'boost' and scaled to jump height. According to the results of strength (Leg Press 45: 157,08  43,30 kg Leg Extension: 72,08  12,86 kg), anthropometry (arm circumf.: 26,04  3,25 cm, thigh circumf.: 50,47  7,65 cm, sholder circumf.: 95,97  8,00 cm, elbow diam.: 4,74  0,51 cm, wrist diam.: 3,21  0,34 cm, knee diam.: 7,89  0,58 cm, biacromial diam.: 37,49  3,81 cm and bi-iliac diam.: 25,43  4,34 cm) and body composition (BMI: 20,74  4,00 kg / m² and% fat: 8,45  4,28), only stature showed a linear correlation (r= 0,595) to the values of vertical jump (height: 47,80  4,35 cm) performance. This anthropometric variable was one able to influence the height of performance by modifying it self, perhaps by maturity. However maturity may be an implicity feature of performance, since force is a concerned effect of the growth. Otherwise technique could play a mains role to the performance of the 'boost'. It can be conclude that possibly is advantageous for water polo athlete be higher and more mature for the realization of 'boost', and the training directed for the technique, but is necessary muscle fitness for the holder

Surgical treatment of type I neuritis in a teenage boy with borderline tuberculoid leprosy

Exacerbation of the immune response against Mycobacterium leprae can lead to neuritis, which is commonly treated via immunosuppression with corticosteroids. Early neurolysis may be performed concurrently, especially in young patients with a risk of functional sequelae. We report the case of a young patient experienced intense pain in the left elbow one year after the treatment of tuberculoid-tuberculoid leprosy. The pain was associated with paresthesias in the ulnar edge and left ulnar claw. After evaluation, the diagnosis was changed to borderline tuberculoid leprosy accompanied with neuritis of the left ulnar nerve. Early neurolysis resulted in rapid reduction of the pain and recovery of motor function.

Capacidade de força dos membros superiores em competidores de montaria em touros

This study did evaluate the handgrip strength capacity of bull riding practitioners and recreational practitioners in order to obtain parameters of the muscular fitness of subjects undertaken this sports practice. Twenty right-handed subjects were grouped into bull riding athletes (10 individuals at AMT: 174.5 ± 5.2 cm of height, 78.9 ± 12 kg of body weight, 24.7 ± 6.1 years, and 13,8 ± 2.4% for body fat) and non-athletes (10 subjects n-AMR: 178.5 ± 7.3 cm of height, 81.2 ± 8.8kg of body weight, 21.7 ± 2.3 years, and 13.8 ± 1.9% of body fat). They were underwent to protocols of handgrip strength evaluation by a standard and specific dynamometry (simulating a bull riding posture) of right (DPD e DED) e left (DEP e DEE) hands. The dynamic force values from one repetition to maximum test (1RM) were either obtained in conventional load-based system for upper limbs exercises. The values were compared by the test-t for independent data, assuming ρ ≤ 0.05. The relationship between the values of strength from handgrip and dynamic exercises were drawn by Pearson correlation. The results of the AMT to DPD (43.8 ± 6.8kgf), DPE (39.4 ± 7.7kgf), DED (44.9 ± 5.6kgf), and DEE (39.8 ± 8.3kgf). For the n-AMT in DPD (47.0 ± 3.0kgf), DPE (42.2 ± 6.1kgf), DED (49.2 ± 1.5kgf), and DEE (46.2 ± 4.1kgf). Significant difference was observed between DED and DEE. The strength tests of 1RM at bench press (73.2 ± 12.0kg and 82.0 ± 12.0kg), arm-curl (45.2 ± 8.9kg and 43.8 ± 8.9kg), triceps pulley (67.0 ± 6.3kg and 72.0 ± 6.3kg), and pulley (73.5 ± 8.5kg and 73.7 ± 7.5kg) for groups n-AMT and AMT did not showed differences. Correlations were showed between all handgrip tests and elbow flexor force for AMT, and between DPD and elbow extensor, abductor, adductor and extensor of shoulder for n-AMT. influences to the performance of the force dynamometry. It could be concluded that handgrip force and dynamic strength of upper limbs did not were putative responses for bull riding practice.

Thus, athletes height was one able to influencethe jump performance by modifying it self, perhaps by maturity.

Ultrasound Transient Shear Wave Elasticity Imaging for Tendon Tissue

Degeneration of tendon tissue is a common cause of tendon dysfunction with the symptoms of repeated episodes of pain and palpable increase of tendon thickness. Tendon mechanical properties are directly related to its physiological composition and the structural organization of the interior collagen fibers which could be altered by tendon degeneration due to overuse or injury. Thus, measuring mechanical properties of tendon tissue may represent a quantitative measurement of pain, reduced function, and tissue health. Ultrasound elasticity imaging has been developed in the last two decades and has proved to be a promising tool for tissue elasticity imaging. To date, however, well established protocols of tendinopathy elasticity imaging for diagnosing tendon degeneration in early stages or late stages do not exist. This thesis describes the re-creation of one dynamic ultrasound elasticity imaging method and the development of an ultrasound transient shear wave elasticity imaging platform for tendon and other musculoskeletal tissue imaging. An experimental mechanical stage with proper supporting systems and accurate translating stages was designed and made. A variety of high-quality tissue-mimicking phantoms were made to simulate homogeneous and heterogeneous soft tissues as well as tendon tissues. A series of data acquisition and data processing programs were developed to collect the displacement data from the phantom and calculate the shear modulus and Young’s modulus of the target. The imaging platform was found to be capable of conducting comparative measurements of the elastic parameters of the phantoms and quantitatively mapping elasticity onto ultrasound B-Mode images. This suggests the system has great potential for not only benefiting individuals with tendinopathy with an earlier detection, intervention and better rehabilitation, but also for providing a medical tool for quantification of musculoskeletal tissue dysfunction in other regions of the body such as the shoulder, elbow and knee.

Prognostic value of thumb pain sensation in birth brachial plexopathy

Objective: To evaluate the prognostic value of absent thumb pain sensation in newborns and young infants with birth brachial plexopathy. Methods: We evaluated 131 patients with birth brachial plexopathy with less than two months of age. Pain sensation was evoked by thumb nail bed compression to evaluate sensory fibers of the upper trunk (C6). The patients were followed-up monthly. Patients with less than antigravity elbow flexion at six months of age were considered to have a poor outcome. Results: Thirty patients had absent thumb pain sensation, from which 26 showed a poor outcome. Sensitivity of the test was 65% and specificity was 96%. Conclusion: Evaluation of thumb pain sensation should be included in the clinical assessment of infants with birth brachial plexopathy.

RESULTS OF ULNAR NERVE NEUROTIZATION TO BICEPS BRACHII MUSCLE IN BRACHIAL PLEXUS INJURY

Objective: To evaluate the factors influencing the results of ulnar nerve neurotization at the motor branch of the brachii biceps muscle, aiming at the restoration of elbow flexion in patients with brachial plexus injury. Methods: 19 patients, with 18 men and 1 woman, mean age 28.7 years. Eight patients had injury to roots C5-C6 and 11, to roots C5-C6-C7. The average time interval between injury and surgery was 7.5 months. Four patients had cervical fractures associated with brachial plexus injury. The postoperative follow-up was 15.7 months. Results: Eight patients recovered elbow flexion strength MRC grade 4; two, MRC grade 3 and nine, MRC <3. There was no impairment of the previous ulnar nerve function. Conclusion: The surgical results of ulnar nerve neurotization at the motor branch of brachii biceps muscle are dependent on the interval between brachial plexus injury and surgical treatment, the presence of associated fractures of the cervical spine and occipital condyle, residual function of the C8-T1 roots after the injury and the involvement of the C7 root. Signs of reinnervation manifested up to 3 months after surgery showed better results in the long term. Level of Evidence: IV, Case Series.
