Effects of Pilates on muscle strength, postural balance and quality of life of older adults: a randomized, controlled, clinical trial

[Purpose] The aim of the present study was to determine the effects of Pilates on lower leg strength, postural balance and the health-related quality of life (HRQoL) of older adults. [Subjects and Methods] Thirty-two older adults were randomly allocated either to the experimental group (EG, n = 16; mean age, 63.62 ± 1.02 years), which performed two sessions of Pilates per week for 12 weeks, or to the control group (CG, n = 16; mean age, 64.21 ± 0.80), which performed two sessions of static stretching per week for 12 weeks. The following evaluations were performed before and after the interventions: isokinetic torque of knee extensors and flexors at 300°/s, the Timed Up and Go (TUG) test, the Berg Balance Scale, and the Health Survey assessment (SF-36). [Results] In the intra-group analysis, the EG demonstrated significant improvement in all variables. In the inter-group analysis, the EG demonstrated significant improvement in most variables. [Conclusion] Pilates exercises led to significant improvement in isokinetic torque of the knee extensors and flexors, postural balance and aspects of the health-related quality of life of older adults.

Anti-inflammatory and analgesic effects of low-level laser therapy on the postoperative healing process

[Purpose] This study aimed to evaluate the anti-inflammatory and analgesic effects of intraoral application of low-level laser therapy (660 nm) to control pain, swelling and interincisal opening following the extraction of mandibular third molars. [Subjects and Methods] Ten patients underwent removal of lower third molars using the same surgical protocol and pharmacological approach. In the postoperative period, all patients received four consecutive daily sessions of low-level laser therapy, beginning 24 hours after the surgery. Intraoral applications using the diode laser with 660 nm wavelength in the continuous scan mode were performed covering the entire surgical area, which was divided into four quadrants, each of 1 cm2 area at a distance of 1 cm. The energy applied at each point was 5 J/cm2 during 8 seconds. [Results] The swelling and interincisal opening returned to normal 24 hours after the first low-level laser therapy application (Friedman test). Moreover, the pain intensity was reduced on the third postoperative day, according to the Friedman test. [Conclusion] Low-level laser therapy (660 nm), at the dosimetry used in this study, was effective in reducing postoperative pain and swelling following oral surgery.

Laser Biomodulation on L 929 Cell Culture

OBJECTIVE The aim of the present study was to analyze the effects of photobiomodulation using a 904-nm diode laser at two energy densities (6 J/cm(2) and 50 mJ/cm(2)) on L929 fibroblast cells. BACKGROUND Low-power laser irradiation (LPLI) is a non-pharmacological resource that induces important in vitro photobiomodulation on cell cultures and tissues. METHODS Irradiation was performed for three days at 24-h intervals. After each interval, the cells were stained with MitoTracker Orange and DioC6 dyes to assess the photobiomodulatory effects of irradiation on mitochondrial activity and changes in the endoplasmic reticulum. The MTT assay [3-(4.5-dimethylthiazol-2-yl)-2.5 diphenyltetrazolium bromide] was used to evaluate cell proliferation. RESULTS AND CONCLUSIONS The fluorescence microscopy assessment of mitochondria and endoplasmic reticulum in cells irradiated with 6 J/cm(2) and 50 mJ/cm(2) demonstrated intense mitochondrial activity, which was confirmed by DioC6 staining. Reticular activity was observed stemming from increased protein synthesis. Photobiomodulation with 50 mJ/cm(2) was slightly higher than with 6 J/cm(2), as demonstrated by fluorescence microscopy results. Photobiomodulation was also time-dependent, with better results 72-h after irradiation.

Análise da influência da farmacoterapia sobre a qualidade de vida em idosos com osteoartrite

AIMS This study aimed to assess the influence of pharmacotherapy on health-related quality of life of elderly with ostheoartritis. METHODS Longitudinal study involving 91 older adults from both genders (Age: 70.36±5.57 years) from EELO project with self-reported knee or hip ostheoartritis, confirmed by radiographic analysis. Data regarding pharmacotherapy was assessed by a structured questionnaire and the quality of life was analyzed by SF-36 questionnaire at the initial moment and two years thereafter. All domains from quality of life were grouped in physical and mental components for further data analysis. RESULTS A statistically significant decline in health-related quality of life was observed (Wilcoxon test, p<0.05). However, it was observed a slighted decline in physical components in group treated with chondroitin/glucosamine when compared to other groups, according to Kruskal-Wallis test (p=0.007). On the other hand, it was not observed any influence of pharmacological treatment on mental components of health-related quality of life (p>0.05). CONCLUSIONS Treatment with condroitin/glucosamin contributes to a lower decline in physical component while it had no influence on mental component of health-related quality of life in older adults with ostheoartritis.

Translation, transcultural adaptation and validation of the Nordic questionnaire for the evaluation of low back pain in Brazilian adolescents

Background: Low back pain has been configured as a public health problem capable of compromising functional capacity, even in adolescents, however, there are no validated instruments for Brazilian adolescents. Objective: Validate the psychometric properties of the Nordic questionnaire for the evaluation of low back pain in Brazilian adolescents. Methods: The sample consisted of 150 adolescents (84 female), aged between 15 and 19 years. The Nordic questionnaire for the evaluation of low back pain in adolescents, was translated and culturally adapted into Portuguese (Brazil). A committee of experts followed the entire validation process. The questionnaire was administered in two moments, with a 14-day interval. Statistical analysis involved Kappa index. Results: After the slight modifications in the translation process, the expert committee considered that the Brazilian Portuguese version of the questionnaire presented semantic, idiomatic, cultural and conceptual equivalence. The results showed that, among the 15 items considered in the eight questions of the questionnaire, 66.6% presented substantial agreement (kappa between 0.61-0.80). The other items presented almost perfect agreement (kappa > 0.80). Conclusion: The Nordic questionnaire for the evaluation of low back pain in adolescents, after being translated and culturally adapted into the Portuguese (Brazil) language, showed adequate psychometric properties, with high reproducibility in all items, demonstrating that it can be used safely to evaluate the low back pain in Brazilian adolescents.

Effect of therapeutic ultrasound of low intensity pulsed and continuous in fibroblastic cells in vitro

Introduction: The ultrasound is widely used clinical practice focused on tissue repair, because it is a secure resource, minimally-invasive and low investment. However, despite the effects of ultrasound have been well described, the ideal relationship between dose and effect, still needs to be better elucidated and bounded. Objective: In this way, the objective of this study was to evaluate the influence of irradiation pulsed ultrasound and continuous in the viability of fibroblastic cells L929 in vitro. Method: The cells were distributed in TPP plates 12 wells in the concentration of 5x105 cells/μL and subdivided into the following groups: G1: control (not received radiation), G2: irradiated to 0.5 W/cm2 30% and G3: irradiated to 0.5 W/cm2 100%. Then received ultrasonic irradiation with intervals of 24, 48 and 72 hours, and after 24 hours of each irradiation was performed MTT cytotoxicity cell. Results: Among the three groups analyzed, only the G2 group showed a significant difference between the time 48 and 72 hours (p=0.05). In other times, despite variation in the percentage of viable cells, were not significant. When compared to peers at post-test, it was possible to observe a difference of 29% of viable cells between the groups G1 and G2 (p=0.05). However, the biggest difference was observed between the groups G2 and G3 (p=0.05). Conclusion: In this way, it can be concluded that irradiation pulsed ultrasound showed higher proliferation of fibroblasts L929 in time 48 hours, whereas in group irradiated in continuous mode, there was no statistically significant difference between the times.
