It is therefore essential to detect early functional decreases in the presence of pain related to osteoarthritis. Objective: This cross-sectional study aimed to assess the impact of pain on functionality, postural control and fall risk in women aged between 45 to 64 years old. Methods: Twenty-one (21) women aged 45 to 64 were evaluated by clinical and functional measures such as a pain questionnaire (Lequesne Index), functional tests (Stair Step Test, 5 times sit-to-stand, 6MWD, Timed-up and Go) and postural performance (under force platform). Women were classified into 2 groups from the Lequesne Pain Index (PI): low pain (score ≤ 9) and strong pain (score ≥ 10) for subsequent comparisons on functionality (physical and postural control performance). Results: A significant impact was observed between the pain index (strong PI) and 3 of the 4 func...

Stress cracking tests were performed in accordance to ASTM D5397: Notched Constant Tensile Load Test (NCTL) and Single Point-Notched Constant Tensile Load Test (SP-NCTL). Tests were conducted to the fresh sample at 50ºC (standard test) and at 70ºC (accelerated condition) in order to compare the SC values. Results from accelerated tests (NCTL) showed, for instance, a total economy of 390 hours (comparing load stages of 25% yield stress) to perform the tests.

Dans un premier temps, nous avons vérifié si le profil de la fréquence cardiaque nocturne des enfants et des adolescents pouvait être regroupé selon le diagnostic. Pour ce faire, la fréquence cardiaque nocturne de 67 adolescents anxieux et 19 sujets non anxieux a été enregistrée à l’aide d’un équipement ambulatoire. Les résultats de cette étude montrent que le profil de la fréquence cardiaque nocturne chez les enfants anxieux varie selon le diagnostic. Alors que les adolescents non anxieux montrent un profil de la fréquence cardiaque nocturne plat, on retrouve les associations suivantes chez les adolescents ayant un trouble anxieux : a) un profil croissant de la fréquence cardiaque chez les adolescents ayant un trouble d’anxiété de séparation; b) un profil décroissant de la fréquence c...

In a randomized controlled trial, 160 kindergarteners in a music programme, a motor programme, or a control group were examined. Children in the two experimental conditions took part in 19 weekly 40-minute sessions. At pretest and post-test, inhibition control and phonological processing were measured with two subtests from the NEPSY-II. Gross and fine motricity were assessed with the BOT-2 Short Form. Post-test results showed that children in the music condition improved significantly on automatic response inhibition. Phonological processing skills did not differ significantly between the two experimental conditions, but the music condition produced significant improvements over control. These findings corroborate previous evidence that music training contributes substantially to develop executive function and phonological awareness in preschoolers.

PURPOSE: The purpose of this pilot study was to evaluate the impact of FitBit-HR2 (G1) and FitBit-HR2 with kinesiology Dietitian counseling (G2) on the number of steps taken per day. METHODS: 12 sedentary men aged between 18-35 yld were asked to wear a Fitbit watch for 60 days. Six men using FitBit (mean=25.7±3.2 years old, BMI 21.8±3.7 kg/m) were compared to 6 men using FitBit while also receiving kinesiology Dietitian counseling (mean=27.3±5.0 years old, BMI 25.2±8.3 kg/m) in their respective ecological environments. The participants in G2 received four 60-minute individual counseling sessions. RESULTS: Both groups appear to have significantly increased the number of steps they take per day during the study. Participants in G1 took 5838.9±1035.0 steps on average at week 1 and 9029.0 ± 2529.4 steps at week 7 (Cohen’s d = 1.65; p<0.001). Participants in G2 took 3708.2±1340.2 steps on average at week 1 and 8942.9±4456.6 steps at week 7 (Cohen’s d = 1.59; p<0.01). While G2 mean Steps difference (week 7-week 1) is bigger than that of G1, it is too early to suggest that counseling sessions combine with FitBit had an increased value. CONCLUSION: It appears that using a self-monitoring ambulatory device by itself is likely to help sedentary men to increase the step per day number. Future research should involve more sedentary men and women of all ages to help conclude the impact of either FitBit alone and FitBit and counseling.

CONCLUSIONS: The sensorimotor increased activation associated with neuromuscular training is similar to motor recovery after injury and after long-duration (weeks) motor skill training. The increased sensorimotor cortex activation indicates the cortical representation may be functionally increased for knee motor control after the focused intervention. Future work with expanded sample sizes will map whole brain connectivity and other brain region activation changes associated with neuromuscular training.

Firstly, we have verified if the nocturnal sleep pattern of children and adolescents could be grouped by psychiatric disorders. Sixty-seven children and adolescents with anxiety disorders and nineteen non anxious match controls were monitored using ambulatory recording equipment. Results showed that nocturnal heart rate pattern of anxious adolescents would vary accordingly with the diagnosis. While non anxious adolescents exhibit a flat nocturnal heart rate pattern through the night, anxious participants showed the following associations: a) increased nocturnal heart rate pattern associated with separation anxiety disorder; b) decreased nocturnal heart rate pattern associated with generalized anxiety disorder; and c) U shape nocturnal heart rate pattern associated with social phobia. Moreover...

Agility is involved in everyday movements and is essential to the development of sports skills. Recent imaging studies have shown delayed of the cerebral cortex development of near three years in children with ADHD, which could explain MD. This study aims to evaluate Agility in ADHD male adolescents compare to normal controls, group-matched for age. Moreover, if MD in agility is still observable in ADHD, to determine which group age they can be compared with.
