Filter by:The goal of this observational study is to develop and validate cell-free RNA-based biomarkers for predicting a variety of adverse pregnancy outcomes in a pregnant person population. The main question it aims to answer are: 1. Can cell-free RNA-based biomarkers predict which pregnant people are at greatest risk of developing adverse pregnancy outcomes (e.g., preterm birth, preeclampsia)? 2. What is the performance of such biomarkers when predicting an adverse pregnancy outcome (e.g., sensitivity, specificity, PPV, NPV, TPR)?
The present experimental study aims to evaluate the effectiveness and tolerability of isoinertial strength training of the hamstrings using machines in patients with ACL-R during the intermediate post-intervention phases.
Anterior cruciate ligament (ACL) injuries are recurrent, especially in sports. There is still no consensus on the characterization of functional indicators in this clinical condition, as well as their correlation with measuring instruments and clinical functional tests. It is intended to study the changes in functionality of users undergoing this surgery, aiming with functional assessment scales at different times of recovery. This will allow deciding on more adapted recovery strategies, which can meet the musculoskeletal requirements of the user.
The investigators will compare the results of sono-guided femoral nerve block in arthroscopic surgery for anterior cruciate ligament reconstruction under spinal anesthesia.

After rehabilitation completion, there remains large deficiencies between the operative (OP) and non-operative (NOP) limbs in lower-limb outcomes (e.g., size, strength, and function) and these deficits can persist for years. Therefore, further specialized training protocols, such as the ones in the present study, are required to determine if these deficits can be lessened. The proposed project will evaluate the effect of 8-weeks of single-leg and double-leg lower-body resistance training on musculoskeletal function in individuals with a previous anterior cruciate ligament (ACL) reconstruction (ACLR) in a randomized control trial. The study will recruit 30-40 males and females between 18-35 years of age that have undergone a previous ACLR. Participants will be randomized to either the single-leg/unilateral (UL) or double-leg/bilateral (BL) training groups. Training will occur three times per week for 8-weeks. The UL group will participate in exercises such as split squats, single-leg deadlifts, or single-leg squats. The BL group will utilize exercises such as double-leg squats, conventional deadlifts, and leg presses. One week prior to (PRE) and one week after (POST) the training program, all participants will undergo a testing battery. Musculoskeletal ultrasound will measure quadriceps and hamstrings muscle cross-sectional area (mCSA), fascicle length (FL), and pennation angle (PA) of both OP and NOP limbs. Strength will be assessed through maximal voluntary isometric contractions (MVIC) for the quadriceps and hamstrings, and one-repetition maximum tests for single-leg leg extensions, leg curls, and leg press. Lower-limb function will be assessed through single-leg and double-leg jumps on a dual force plate system for jump height, impulse, rate of force development, and peak force. Data will be analyzed via separate mixed-factorial analyses of variance for the within-subjects factor of leg (OP vs. NOP) and time (PRE vs. POST) and the between-subjects factor of biological sex (male vs. female) and group (UL vs. BL). Post-hoc analyses will include lower-order ANOVAs and t-tests as pairwise comparisons when significance is detected. Significance will be established at p≤0.05. The results of this study will assist practitioners, coaches, sport scientists, and most importantly, the athletes, in the development of post-rehabilitative strength training protocols designed to reduce between-limb discrepancies.
The aim of this observational study is to examine the connection between bone-tendinous defects after BTB graft harvest and the development of anterior knee pain.
Increased knowledge is needed about new methods how to treat patients with Achilles tendon ruptures (ATR). A goal is to be able to individualize as well as improve treatment beyond the question about if surgery should be used or not. An overall aim of the project is to, in a randomized controlled trial (RCT), explore what impact a new treatment method with Neuromuscular Electrical Stimulation (NMES) - attached on the patients ́ calf muscles on the injured leg - in the early stages after an ATR, may have on tendon length, functional performance, biomechanical variables and patient reported outcome, both in the short and long term after the injury. 70 patients are planned to be included in this RCT and will be evaluated 3,6 and 12 months after their injury. Primary outcome will be heel-rise height. Secondary outcome will be tendon length, jumping ability, patient- reported outcome and biomechanical loading pattern. There is also a need to explore if the patients ́ loading patterns improve after treatment with NMES. Therefore, biomechanical variables in lower leg during walking and jumping will also be evaluated one year after their injury. The planned studies include completely new ways of exploring how to optimize the rehabilitation after an ATR. Since there might be an increased risk for overuse injuries in the healthy limb, there will also be focus on how the non- injured limb may be affected of an ATR. Taken together, this new knowledge can be helpful in the clinical setting to individualize and optimize patients' treatment and rehabilitation with the goal to guide the patient return to the same, or higher level of, physical activity as before the injury.
Anterior knee pain which might be due to patellofemoral malalignment is an inevitable post operative complication after an ACL reconstruction (ACLR). We combined the double bundle ACLR technique with lateral release technique to prevent patellofemoral malalignment post ACLR.
The study gives an overview of surgically treated rotator cuff injury patients in Tartu University Hospital Sports Traumatology Centre during 2013-2019 and evaluates the integrity of rotator cuff at minimum 5 years after atraumatic rotator cuff tendon repair. First stage of the study describes the study population, etiology of the injury (traumatic/atraumatic) and aims to answer the question whether the arthroscopic findings are in line with the preoperative imaging studies or not. Second stage of the study focuses on atraumatic tendon tears assessing structural integrity of the tendons 5 years after repair using ultrasound imaging. The main question is - does the findings correlate with clinical outcomes and patient satisfaction. Participants of the second phase of the study will be asked for an appointment to have their shoulders examined with ultrasonography and clinical outcomes are measured using the American Shoulder and Elbow Surgeons (ASES) Score, The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and The Constant-Murley score (CMS).
