RESUMO
BACKGROUND: The Close Kinetic Chain Upper Extremity Stability Test (CKCUES test) is a low cost shoulder functional test that could be considered as a complementary and objective clinical outcome for shoulder performance evaluation. However, its reliability was tested only in recreational athletes' males and there are no studies comparing scores between sedentary and active samples. The purpose was to examine inter and intrasession reliability of CKCUES Test for samples of sedentary male and female with (SIS), for samples of sedentary healthy male and female, and for male and female samples of healthy upper extremity sport specific recreational athletes. Other purpose was to compare scores within sedentary and within recreational athletes samples of same gender. METHODS: A sample of 108 subjects with and without SIS was recruited. Subjects were tested twice, seven days apart. Each subject performed four test repetitions, with 45 seconds of rest between them. The last three repetitions were averaged and used to statistical analysis. Intraclass Correlation Coefficient ICC2,1 was used to assess intrasession reliability of number of touches score and ICC2,3 was used to assess intersession reliability of number of touches, normalized score, and power score. Test scores within groups of same gender also were compared. Measurement error was determined by calculating the Standard Error of the Measurement (SEM) and Minimum detectable change (MDC) for all scores. RESULTS: The CKCUES Test showed excellent intersession reliability for scores in all samples. Results also showed excellent intrasession reliability of number of touches for all samples. Scores were greater in active compared to sedentary, with exception of power score. All scores were greater in active compared to sedentary and SIS males and females. SEM ranged from 1.45 to 2.76 touches (based on a 95% CI) and MDC ranged from 2.05 to 3.91(based on a 95% CI) in subjects with and without SIS. At least three touches are needed to be considered a real improvement on CKCUES Test scores. CONCLUSION: Results suggest CKCUES Test is a reliable tool to evaluate upper extremity functional performance for sedentary, for upper extremity sport specific recreational, and for sedentary males and females with SIS.

OBJECTIVE: The present study aimed to assess the reliability of intra and inter-examiner subacromial impingement index (SII) measures obtained from radiographs. MATERIALS AND METHODS: Thirty-six individuals were enrolled and divided into two groups: control group, composed of 18 volunteers in good general health without shoulder problems, and a group of 18 patients with subacromial impingement syndrome (SIS). Radiographic images were taken with the dominant upper limb in neutral rotation, while the volunteers held their arm at 90 degrees of abduction in the frontal plane. The beam of radiation at 30 degrees craniocaudal inclination was used to provide an antero-posterior image view. Three blinded examiners each performed three measurements from the subacromial space (SS) and the anatomical neck of the humerus (NH). The SII was calculated as the ratio of the SS and the NH measures. The mean values of SII were compared using t-tests. The intra-class correlation coefficient (ICC) was used to assess intra- and inter-examiner reliability of the measures. RESULTS: The mean values of SII were greater for the control group (0.12) than for the SIS group (0.08; p = 0.0071). SII measurements showed excellent intra (0.96-0.99) and inter-examiner reliability (0.94) for both the control and SIS group. CONCLUSION: The results of this study show the potential use of the SII; a greater mean value for the control group compared to the SIS group and excellent reliability for intra- and inter-examiner measurement. Validation studies of the index should be conducted to correlate the index with clinical findings from subacromial impingement syndrome.

Indivíduos com lesão do ligamento cruzado anterior (LCA) possuem importantes alterações funcionais na musculatura periarticular do joelho. Sendo assim, é de suma importância caracterizar tais alterações, bem como enfatizar um efetivo protocolo de reabilitação para esses indivíduos, com conseqüente retorno às atividades físicas. O objetivo deste estudo foi analisar o comportamento da freqüência mediana (Fmed) em indivíduos com lesão do LCA durante contrações isométricas em exercícios de cadeia cinética aberta (CCA) e fechada (CCF). Entre lesados e não lesados, 40 indivíduos realizaram a extensão do joelho através da contração isométrica voluntária máxima (CIVM) nos aparelhos leg extension e leg press a 30°, 60° e 90° de flexão do joelho. Os resultados revelaram valores da Fmed menores para indivíduos com lesão do LCA quando comparados com o membro contralateral e grupo controle em CCA (p < 0,05). Já exercícios em CCF não apresentaram diferença estatística significativa (p > 0,05) na comparação entre os grupos, não evidenciando esse tipo de lesão. Portanto, a Fmed parece ser uma ferramenta eletromiográfica eficaz na caracterização da lesão crônica do LCA. Além disso, exercícios em CCF parecem ser os mais indicados para a reabilitação desses indivíduos.
Subjects with injury of the anterior cruciate ligament (ACL) have shown relevant functional alterations in the knee muscles. Therefore, it is extremely important to characterize these alterations, as well as to emphasize an efficient rehabilitation protocol for these subjects and consequently return them to physical activities. The purpose of this study was to investigate the medium frequency (Fmed) of the electromyographic signal in ACL subjects with lesions during isometric exercises in open (OKC) and closed kinetic chain (CKC). Forty subjects (with and without lesion) performed knee extension during maximal voluntary isometric contraction on Leg Extension and Leg Press at 30°, 60° and 90° of knee flexion. The results showed smaller Fmed values for ACL deficient subjects when compared with counter lateral and control groups in OKC exercises (p<0,05). However, there was not significant difference in CKC exercises between groups (p>0,05), not showing thus, this kind of injury. Therefore, the Fmed can be considered an efficient tool in the LCA injury characterization. Moreover, CKC exercises seem to be the best alternative for rehabilitation of the ACL deficient subjects.

Los resultados revelaron valores de Fmed menores para individuos con lesión cuando al ser comparados con el miembro contra lateral y el grupo control en CCA (p < 0,05). Por otro lado, ejercicios en CCC no presentaron diferencia estadística significativa (p > 0,05) al compararse entre los grupos, no dando evidencia de este tipo de lesión. Por lo tanto, Fmed parece ser una herramienta electromiográfica eficaz en la caracterización de la lesión crónica de LCA. Además de esto los ejercicios en CCF parecen ser los más indicados para la rehabilitación de estos individuos.
