RESUMEN

Background Wrist arthroscopy has become a commonly used tool for the management of adults with distal radius fractures (DRFs), although its implementation requires technical competence. This systematic review and meta-analysis appraised the available evidence concerning the contribution of wrist arthroscopy to the functional and radiological outcomes of patients with DRFs operated with arthroscopic assistance. Methods Randomized control trials were identified through five principal electronic databases on May 31, 2022: Web of Science, Scopus, EBSCO, Embase, and PubMed. Two authors independently performed the search and data extraction and assessed risk of bias (RoB) using the Cochrane RoB tool. Results A total of 1,780 relevant abstracts and citations were extracted in the preliminary search, which yielded 6 trials that met the eligibility criteria, and 3 studies were included in the quantitative synthesis. The overall pooled mean difference (MD) estimate showed no significant difference in the Disabilities of the Arm, Shoulder, and Hand scores between surgical groups with and without arthroscopic assistance (MD = 0.77 points, 95% confidence interval = -6.58 to 5.03, p = 0.79), with substantial heterogeneity (I 2 = 85%). Conclusion There was low-quality evidence that wrist arthroscopy conveyed not clinically or statistically significant difference to functional outcomes of patients with DRFs. However, our findings are limited by the numbers of studies included and lack of long-term follow-up, although they do provide a good starting point for future quality research.

RESUMEN

INTRODUCTION: Few evidence on the use of antipsychotics in people with intellectual disabilities and challenging behaviors, generates the need to develop studies that contribute to collect, compare and synthesize the available information. The present systematic review and meta-analysis aims to determine the clinical efficacy of antipsychotic medication in reducing critical episodes in this population. METHODS: We searched Web of Science, Scopus, EBSCO, Embase, and PubMed for randomized controlled trials of antipsychotic medication versus placebo. Preliminarily yielded 1354 abstracts and citations; six studies with 274 subjects met the inclusion criteria of studies with experimental design, longitudinal type, with pre- and post-intervention measurements. RESULTS: There is evidence for the use of psychotropic drugs in the acute management of challenging behaviors in patients with intellectual disability (SMD=-0.85; 95% CI=-1.69 to -0.01; p=0.05). CONCLUSIONS: Our results coincide with the recommendations on the efficacy of the use of antipsychotics. Although our study provides evidence, the limited number of studies included in this research does not allow us to obtain totally conclusive results, although it can be considered as a guide for future studies.

RESUMEN

Resumen El estudio tiene como propósito analizar la fiabilidad de la prueba de 8 lanzamientos de 3 diferentes variantes de lanzamientos de balonmano en estudiantado universitario. 33 varones, 20 ±1,9 años; peso 72,39±8,9 kg; altura 176,75 ±6,07 cm; IMC 23,14±2,3. Los sujetos participantes fueron evaluados en 2 sesiones separadas entre sí por un lapso de una semana. Ejecutaron lanzamientos hasta quedar registrados 8 mediciones en cada una de las pruebas, lanzamientos inespecíficos, en apoyo y en carrera con 3 pasos, se registró la velocidad de lanzamiento con un radar posterior a la portería. La fiabilidad del promedio de las puntuaciones del test de 8 medidas entre la primera sesión y la segunda con una prueba test-retest, se obtuvieron los siguientes resultados: en el lanzamiento inespecífico se obtuvo un ICC= (0,86) entre el 95% de confianza, un de CV= (7,43%) y un ES= (0,08). Para el lanzamiento con apoyo se obtuvo un ICC= (0,94) al 95 % de confianza, un de CV= (4,71 %) y un ES= (-0,09). Para el lanzamiento con carrera se obtuvo un ICC= (0,96) al 95 % de confianza, un de CV= (4,00 %) y un ES= (0,05). Este estudio ha demostrado que la prueba de 8 lanzamientos y las 3 variantes es una medida de rendimiento confiable y estable para estudiantes de nivel universitario sin experiencia en el balonmano, en relación con las variables del lanzamiento, las 3 fueron fiables, solo la variable inespecífica fue menor en comparación al lanzamiento con apoyo y con carrera.

Abstract This study aims to analyze the reliability of the test of 8 throws of 3 different variants of handball throws in university students. The participants were 33 males, 20 ± 1.9 years; weight 72.39 ± 8.9 kg; height 176.75 ± 6.07 cm; BMI 23.14 ± 2.3. They were evaluated in 2 sessions separated from each other by a period of one week. The participants executed throws until 8 measurements were recorded in each of the tests, unspecific throws, in support and in the race with 3 steps; the launch speed was recorded with a radar behind the goal. The reliability of the average of the test scores of 8 measurements between the first session and the second was measured with a test-retest test. The following results were obtained: in the nonspecific launch, an ICC= (0.86) was obtained between 95% of confidence, one of CV= (7.43%) and one ES = (0.08). For the toss with support, an ICC = (0.94) was obtained at 95% confidence, one of CV = (4.71%) and an ES = (-0.09). For the running throw, an ICC = (0.96) was obtained at 95% confidence, one of CV = (4.00%) and one ES = (0.05). This study has shown that the test of 8 throws and the 3 variants is a reliable and stable performance measure for university-level students without experience in handball; in relation to the throw variables, all 3 were reliable. Only the nonspecific variable was lower compared to the supported and running pitch.

Resumo O estudo tem como objetivo analisar a confiabilidade do teste de 8 arremessos de 3 variantes diferentes de arremessos de handebol em estudantes universitários. 33 homens, 20 ±1,9 anos; peso 72,39±8,9 kg; altura 176,75 ±6,07 cm; IMC 23,14±2,3. Os participantes foram testados em 2 sessões separadas por um lapso de 1 semana. Os participantes executaram arremessos até poder registrar 8 medições em cada um dos testes, arremessos não específicos, com apoio e correndo com 3 passos. A velocidade de arremesso foi registrada com um radar pós-gol. A confiabilidade da média dos resultados dos testes de 8 medições entre a primeira sessão e a segunda com um teste de retorno, deu os seguintes resultados: no teste de lançamento não específico, foi obtido um ICC= (0,86) com 95% de confiança, um CV= (7,43%) e um ES= (0,08). Para o lançamento apoiado obtivemos um ICC= (0,94) a 95% de confiança, um CV= (4,71%) e um ES= (-0,09). Para o arremesso de corrida obtivemos um ICC= (0,96) a 95% de confiança, um CV= (4,00%) e um ES= (0,05). Este estudo mostrou que o teste de 8 lances e as 3 variantes é uma medida de desempenho confiável e estável para estudantes universitários sem experiência em handebol. Em relação às variáveis de arremesso, todas as 3 foram confiáveis, apenas a variável não específica foi menor em comparação com o arremesso com suporte e com corrida.

RESUMEN

Throwing velocity is one of the most important factors for scoring goals in handball. This study aimed to identify the type of throw and procedure for selecting the final test outcome that provide throwing velocity with the greatest reliability. Fifteen experienced handball players and 33 non-experienced participants were tested in two sessions. Each session consisted of 4 trials of 3 different throwing tests (unspecific, 7-meters, and 3-steps). The maximum value of 4 trials, average value of 4 trials, and average value of the 3 best trials were considered. Throwing velocity was highly reliable (coefficient of variation [CV]≤3.3%, intraclass correlation coefficient≥0.89) with the exception of the unspecific throw for the non-experienced group (CV≥5.9%, intraclass correlation coefficient≤0.56). The 3-steps throw (CV=1.7%) was more reliable than the 7-meters throw (CV=2.1%) (CVratio=1.19) and unspecific throw (CV = 3.8%) (CVratio=2.18), the 3 procedures provided a comparable reliability (CV range=2.4-2.6%; CVratio≤1.07), and the experienced group (CV=1.0%) presented a higher reliability than the non-experienced group (CV=4.0%) (CVratio=3.83). These results support the 3-steps throw to maximise the reliability of throwing velocity performance.
