There has been controversial results regarding the reliability of electromyographic parameters assessed during stair ascent and descent in individuals with patellofemoral pain syndrome (PFPS). Therefore, this study aims to determine the reliability of time and frequency domain electromyographic parameters on both gestures in women with PFPS. Thirty-one women with PFPS were selected to participate in this study. Data from vastus lateralis and medialis were collected during stair deambulation. The selected parameters were: automatic onset, median frequency bands of low, medium and high frequency. Reliability was determined by intraclass correlation coefficient and the standard error of measurement. The frequency domain variables have shown good reliability, with the stair ascent presenting the best rates. On the other hand, onset has proved to be inconsistent in all measures. Our findings suggest that stair ascent is more reliable than stair descent to evaluate subjects with PFPS in the most cases.

Individuals with patellofemoral pain are often diagnosed through static clinical tests, in scientific studies and clinical practice. However, the adaptations seem to appear in dynamic conditions. Performing static vs. dynamic evaluations of widely used measures would add to the knowledge in this area. Thus, the aim of this study was to determine the reliability and differentiation capability of three rearfoot eversion measures: rearfoot range of motion, static clinical test and static measurement using a three-dimensional system. Method: A total of 29 individuals with patellofemoral pain and 25 control individuals (18-30 years) participated in this study. Each subject underwent three-dimensional motion analysis during stair climbing and static clinical tests. Intraclass correlation coefficient and standard error measurements were performed to verify the reliability of the variables and receiver operating characteristic curves to show the diagnostic accuracy of each variable. In addition, analyses of variance were performed to identify differences between groups. Findings: Rearfoot range of motion demonstrated higher diagnostic accuracy (an area under the curve score of 0.72) than static measures and was able to differentiate the groups. Only the static clinical test presented poor and moderate reliability. Other variables presented high to very high values. Interpretation: Rearfoot range of motion was the variable that presented the best results in terms of reliability and differentiation capability. Static variables do not seem to be related to patellofemoral pain and have low accuracy values.

Methods: A cross-sectional study was performed of 29 individuals divided into three groups: young persons (n=10); falling elderly individuals (n=7) and non-falling individuals (n=12). Gait analysis was performed based on the recording of three walking gait cycles along an 8 meter platform, which was attached to a force plate with a recording frequency of 200 Hz. Gait cycles were also recorded by three video cameras positioned perpendicular to the force plate with a recording frequency of 60 Hz. The data analyzed was: average step velocity, stance time, Froude number and anteroposterior ground reaction force. Results: The average step velocity was higher among young persons and there was no difference in the Froude number among the three groups. During the stance and impulse phase, anterior and posterior force was higher among young persons than in the non-falling elderly group. The foot stance time of young individuals was also lower than the nonfalling elderly group (p=0.000) and the foot stance time of the falling elderly group was lower than that of the non-falling elderly group (p=0.004). Conclusion: Falling and non-falling elderly persons have different gait biomechanical characteristics than young women, other than with respect to the Froude number. Furthermore, falling elderly persons spend more time in the gait swing phase than non-falling elderly persons.

Methods: The sample consisted of two groups: the Elderly Group (EG; n=10) and the Young Group (YG; n=16). A ladder test consisting of seven steps, with a force plate coupled to the fourth step to acquire kinetic data and determine the moment of foot contact with the step, was used, as well as a system of three-dimensional kinematics with four infrared cameras. The volunteers descended the stairs continuously, at a self-selected speed and pace. The Student's t-test was used for independent samples and the Pearson correlation test was used to test the correlation of the variables, with a level of significance of α=0.05. Results: The results showed a significant difference between the YG group (240.7±10.5 g/s) and the EG group (186.4±13.2 g/s) for mean peak knee angular velocity. Regarding peak vertical force (Fz), YG had a higher magnitude of force (1.39±0.03) than EG (1.15±0.02), with a significant difference between the groups (p=0.00). The results also showed a positive correlation between variables (r=0.4). Conclusion: The results indicate that elderly persons have a lower knee angular velocity and lower vertical force during stair descent than young people and that there was a correlation between the variables.

Fifteen healthy young subjects performed an isometric leg extension test in two different condition phases: i) maximum test for determining the maximum voluntary isometric contraction, and ii) fatigue test for exercises executed at 50% of the maximum voluntary contraction in three distinct periods with seven-day intervals between the tests. To quantify the co-contraction between the vastus medialis and vastus lateralis muscles, the signals overlapped and the intersection area was calculated. The data reliability was verified with the intraclass correlation coefficient (ICC) and standard error measurement (SEM). Values of median frequency and root mean square for both muscles showed a significant difference between the beginning and the end of the test, which indicates occurrence of the neuromuscular fatigue. The median frequency and root mean square ICC v...

It is very important to undertand the normal walking pattern adopted by the young and healthy, in order to be able to study the changes resulting from pathological conditions. Therefore, this study aims to make a descriptive analysis of kinematic and temporal parameters of one step thoughout a walking condition. The variables analyzed were the joint angles of the lower limb, duration and step length of young female adults. In addition, the study compares whether there are differences in the walking pattern among three repetition trials of the step gesture. Ten women aged between 18 and 23 years participated in the study which consists of recording the step biomechanical variables while walking. No significant differences were found between the three step trials analyzed. The values found for the stride duration and length were 0.73 s. and 125.86 cm respectively. Concerning the step duration and length were found 0.39 s. and 35.93 cm. The mean values for the hip were 166° and 188°; for the knee 177° and 151° and for the ankle angle 120° and 123° in the stance phase and in the impulse phase, respectively.
