SUMMARY Parkinson's disease is the second most common neurodegenerative disease, with an estimated prevalence of 41/100,000 individuals affected aged between 40 and 49 years old and 1,900/100,000 aged 80 and over. Based on the essentiality of ascertaining which wearable devices have clinical literary evidence and with the purpose of analyzing the information revealed by such technologies, we conducted this scientific article of integrative review. It is an integrative review, whose main objective is to carry out a summary of the state of the art of wearable devices used in patients with Parkinson's disease. After the review, we retrieved 8 papers. Of the selected articles, only 3 were not systematic reviews; one was a series of cases and two prospective longitudinal studies. These technologies have a very rich field of application; however, research is still necessary to make such evaluations reliable and crucial to the well-being of these patients.

Purpose. The present study aimed to compare the strength performance in the one-repetition maximum (1rM) test with a knee extension machine among different ranges of motion (rOMs), and to compare the force reduction after the performance of a dynamic exercise configured with different rOMs. Methods. Nine women (mean ± standard deviation: age: 24.2 ± 3.5 years; height: 166.5 ± 4.1 cm; body mass: 68.35 ± 4.14 kg) with no strength training experience and no history of injury performed (cross-over design) tests of 1rM with a knee extension machine in the following rOMs: 100-65° of knee flexion (INITIAL rOM ), 65-30° (FINAL rOM ), and 100-30° (FULL rOM ) (0° = knee full extended). Further, the volunteers performed, in each rOM, 3 sets of 7 repetitions at 60% of 1rM (specific to rOM assessed) with 3-minute rests between sets with 2 seconds for concentric and eccentric phases. Before and 2 minutes after the training, the maximum torque values at 100° and 30° of knee flexion were registered to calculate the force reduction. Results. The ANOVA test identified that the maximum torque pre-training values were greater than the post-training values (p = 0.02), and a greater torque reduction occurred at 30° of knee flexion than at 100° (p = 0.001). Conclusions. The results suggest that rOM may influence maximum strength performance, and the force may reduce similarly along the angles.

Background: Athletes generally exceed the limits of the body, which can result in various lesions. The pediatric musculoskeletal system is particularly susceptible to lesions through overuse for various reasons including an immature growth plate. While spinal column lesions are relatively rare, they can lead to permanent disability. Studies on spinal lesions in young athletes are rare. To assess abnormalities frequency of the lumbar region in asymptomatic young soccer players.Methods: Cross-sectional study. Male adolescents from schools of grassroots soccer clubs and non-practicing activity controls were included by convenience. The abnormalities frequency. of the lumbar region was evaluated by magnetic resonance imaging (MRI), performed using 1.5T devices with multi-channel coils in model equipment models. The types of lesions evaluated were general, warning signs, instituted, anterior and posterior, and of the column. Comparisons between groups and the relative percentage of each lesion type were compared by Pearson’s chi-squared test and Fischer’s exact test. The inter and intra-observer analyses were compared by the Kappa test.Results: Forty-five adolescents were included, of whom 25 (56%) were soccer-practicing teenagers. No significant differences were identified between the variables age (P=0.960) and the body mass index (BMI) Z-score (P=0.540) between the group of soccer players and the controls. However, the percentages of lesions (general, instituted, anterior and posterior, and in the spinal column) were significantly higher in the practicing football group than in the control group (P=0.002, P<0.001, P= 0.012, and P=0.006, respectively).Conclusion: Young adolescent asymptomatic soccer players have more lumbar spine lesions than less active controls who do not practice sports regularly.
