Filter by:The goal of this observational study is to understand how diffusion tensor imaging (DTI) relates to other traditional measures and knee function. The main question it aims to answer is: Will regions of known patellar tendon pathology present with smaller DTI scalar parameters, shorter fiber length, and lower fiber density compared to the contralateral tendon and healthy regions in the ipsilateral tendon. Participants will: - undergo MRI and ultrasound imaging - perform knee function test - complete questionnaires
Chronic tendinopathies (CT) have a high prevalence (30% of musculoskeletal injuries), causing pain, decreased physical activity and functionality, as well as limitations in daily life. Virtual reality (VR) fosters patient recovery through playful activities that promote competitiveness, stimulates motivation and continuous attention, allows individualizing the exercise program, objectively assessing the execution of the treatment and monitoring the patient's evolution. Therefore, the VIRTENDON-REHAB project aims to conduct a low-risk randomized controlled clinical trial to analyze the efficacy of a VR-based physical rehabilitation program in a population diagnosed with CT on pain, functionality, range of motion, strength, muscle activation pattern, kinesiophobia, quality of life, adherence to treatment and patient satisfaction with the use of the system, compared to a control group. Likewise, the aim is to characterize the clinical profile of this population and to know the relationships between the previous variables. Measurements will be taken at the beginning of the intervention, at the end (12 weeks) and 3 months after the end of the intervention. A descriptive analysis will be performed, inter- and intra-group differences will be analyzed by means of t-Student, Wilcoxon, Mann-Whitney U and mixed ANOVA tests. Cohen's d will be used to determine the effect size. Relationships between variables will be analyzed using structural equations. The results obtained will allow improving knowledge on the management of CT using VR, as well as improving clinical care and reducing healthcare costs.
Previous studies have generally investigated patellar tendon stiffness, cross-sectional area of patellar tendon, patellar tendon length, patellar force and patellafemoral forces during decline squat. However, there is just a few study about electromyographic (EMG) activity during the eccentric squating, which is about rectus femoris (RF) recruitment. In the present study the investigators primarly aimed to quantify the activation of RF, vastus lateralis (VL), and vastus medialis obliqus (VMO) during eccentric squat on different decline angle (0, 5°, 10°, 15°, 20°). An additional purpose of our study was to compare the changes in muscle activation at various arc of knee flexion motion (degrees of 0-30, 30-60, 60-90, 0-60, 30-90, 0-90).The investigators hypothesised that the recruitment of RF, VL, and VMO during eccentric squat would differ according to decline angle and arc of motion.
