Filter by:Self-massage is a set of therapeutic techniques performed by the individual using instruments such as a foam roller (i.e., foam rolling [FR]). This technique has been used in rehabilitation to recover myofascial dysfunctions and in physical/sports training, to improve performance in functional and sports activities. Possible changes in the muscle's and tendon's mechanical properties may help to explain the FR effects, however, the dose-response relationship is not clear acutely. Furthermore, body composition also seems to influence the pressure applied to the different tissues during FR, since it can attenuate the forces applied on the tissues. Therefore, the aim of this study is to verify the acute effects of different FR volumes on the plantar flexors' musculotendinous properties in healthy individuals. Twenty healthy subjects (male and female) aged between 18-35 years will perform three different FR conditions: FR90 (3x30s), FR180 (3x60s), and a control condition (CTRL; without the application of any intervention) with a seven-day wash-out period. The Achilles tendon morphological, mechanical, and material properties, medial gastrocnemius passive muscular stiffness, plantar flexors' muscle architecture, and the adipose tissue's thickness, skin temperature and the jump height (assessed during the unilateral countermovement jump) will be obtained. Assessments will be carried out before and immediately after the FR application in the different conditions. Descriptive statistics (mean, standard deviation, and standard error) will be used to present the results. The normality and sphericity of the data will be evaluated using the Shapiro-Wilk and Mauchly tests, respectively. A two-way ANOVA (condition [FR90, FR180, and CTRL] and moments [pre- and post-intervention]) will be used to compare the results. A post-hoc Bonferroni test will be used to find possible differences. A Pearson product-moment correlation test (parametric data) or a Spearman correlation test (non-parametric data) will be used to verify the association between the adipose tissue's thickness and the evaluated parameters. The effect size (Cohen's d) of each condition will be obtained. Responsiveness to conditions (FR90, FR180, and CTRL) will be determined using the typical error.
The purpose of this study is to evaluate whether there is an increased risk of achilles tendon rupture (ATR), retinal detachment (RD) or aortic aneurysm and dissection (AAD) following exposure to fluoroquinolone (FQ) or other antibiotics (amoxicillin, azithromycin, trimethoprim and trimethroprim/sulfamethoxazole) or febrile illness not treated with antibiotics, using a study design that minimizes the impact of confounders not usually captured in health services databases such as heredity or smoking.
The purpose of this study is to determine the effectiveness of eccentric exercise combined with vibration or cryotherapy in Achilles tendon pathology. The investigators hypothesis is that the combined eccentric exercise is better than the results presented by the exclusive eccentric exercise. This intervention differs from the classic studies in that we maintain the intensity throughout the treatment.
Achilles tendon plays a significant role in walking and sporting activities, particularly through ankle joint and lower limbs stability. Ultrasound imaging can be the first-line examination of choice for patients suspected of having Achilles tendon injury, which is more and more frequent. Nowadays, ultrasound elastography can be used to evaluate the viscoelasticity properties of Achilles tendon, however little is known about the reproducibility of the technique. This study aims to evaluate the reproducibility of supersonic shear imaging SWE™ Young's modulus measurements of shear wave velocity (m/s) in Achilles tendon and plantar fascia.
With this project the investigators wish to: 1. Test the reproducibility of Amlang's ultrasound classification by examining the intra- and inter-rater reliability. 2. Investigate whether Amlang's ultrasound classification is able to predict which patients are likely to develop complications when treated non-operatively. 3. Investigate whether Barfod's length measurement is able to predict which patients are likely to develop complications when treated non-operatively.
