Filter by:Adolescents and young adults who hurt their knees playing sports or doing recreational activities can develop joint damage, muscle weakness, inactivity, and weight gain which might lead to an increased risk of osteoarthritis (OA), a disabling joint condition in their later lives. Despite knowing that muscles and joints benefit from exercise, there is no proven exercise-based treatments to delay or even halt the onset of OA after a knee joint injury. The current study will assess if a physiotherapist-guided intervention called Stop OsteoARthritis (SOAR) improves knee muscle strength, physical inactivity, knee-related self-efficacy, and knee-related quality of life in people at risk for osteoarthritis due to a past knee injury. A total of 70 former knee injury participants will be randomly assigned to two groups. One group will immediately start a 16-week SOAR program, while the second will wait for 9-weeks before starting an 8-week SOAR program. Trained physiotherapists will deliver the SOAR program with videoconferencing. The study hypothesis is that participating in the 8-Week SOAR program will improve the knee muscle strength, physical activity levels, knee-related self-efficacy and knee-related quality of life in people discharged from regular healthcare after a sports knee injury. The findings will help researchers understand the ideal length of the program for a future clinical trial in real-world settings.
This study is based on human anatomical data and uses computer-aided engineering (CAE) software such as biomedical image processing software, reverse engineering software, CAD software, and finite element analysis software to create a three-dimensional bracing model. With the help of 3D printing technology, we have developed personalized brace, completed the personalized rapid design and optimization of the three series of support equipment products such as the posterior cruciate ligament brace, ankle ankle brace, and shoulder brace.
The purpose of this study is to conduct a comprehensive clinical and biomechanical screening of high school, collegiate-level, recreational, and Olympic/professional-level athletes with the goal of identifying individual functional and performance deficits that lead to future injury.
Osteoarthritis (OA) is a leading cause of disability worldwide that affects millions of Americans each year. Posttraumatic OA (PTOA) significantly impacts patients after anterior cruciate ligament (ACL) injury and ACL reconstruction (ACLR) with approximately 50% of patients developing PTOA within 20 years of injury or surgery. Knee joint mechanical loading measured via physical activity (i.e. daily steps) is insufficient in individuals after ACLR compared to uninjured individuals. Establishing the beneficial effects of physical activity to promote optimal free-living knee joint mechanical loading and improve knee joint health will aid in the development of cost-effective interventions that prevent PTOA and health burden of the disease.
The purpose of the study is to compare short-term patient reported outcome measures (PROM) of Bone-Quadriceps-Tendon (BQT) autograft with Semitendinosus-Gracilis (STG) and Bone-Patellar-Tendon-Bone (BPTB) autografts following Anterior Cruciate Ligament Reconstruction (ACLR). The PROM used are Knee Injury and Osteoarthrithis Outcome Score (KOOS) and Tegner. Difference in change in KOOS, KOOS subscales and Tegner from preoperative baseline to one-year follow-up and absolute KOOS, KOOS subscales and Tegner at one-year follow-up were evaluated. All of which were BQT compared to STG and BPTB, respectively. The primary outcome is change in KOOS from preoperative baselinge to one-year follow-up. Other outcomes are secondary. The hypothesis was that patients receiving the BQT autograft show similar results in KOOS, KOOS subscales and Tegner as patients receiving STG or BPTB autografts.
The aim of this study is to evaluate different aspects of mental stress aspects and its role as a potential risk factor for traumatic knee injury in youth athletes. Approximately 300 athletes (age 16-19) 50% women) who are involved in high risk sports (soccer, handball and floorball) will be included. The athletes will record his/hers traumatic knee injury together with information about training regimes and some details on injury mechanism on a web-based form. The form also includes questions about mental stressors, such as club exchange, changed game system in addition to conflict within and outside the family, etc, prior to injury. The present study will contribute new knowledge on levels of muscle function and different aspects of mental stress factors that may be related to traumatic knee injury in young athletes.
INTRODUCTION: Core strengthening, balance, and flexibility programs such as Pilates have been advocated to affect running mechanics and prevent lower extremity injuries positively. The purpose of this study was to assess the effects of a 12-week mat-based Pilates exercise program on dynamic knee valgus alignment in runners. METHODS: Thirty-four young male and female adults performed a running protocol at baseline. The protocol consisted of the participants running on a treadmill at a constant five miles per hour (mph) for four minutes. Post-examination, participants were randomly assigned to a Pilates or control group (n=16 and n=18, respectively). A certified Pilates instructor gave the Pilates group a 12-week home-based program. To ensure participants in the Pilates group performed exercises correctly, the Pilates instructor conducted the first session, and provided feedback to each participant. Participants in both groups performed the same running testing protocol every four weeks. Knee valgus was measured as the medial displacement of the knee joint center during the running stance phase. Repeated measures Analysis of Variance (RepANOVA) was calculated at baseline and 4-, 8-, and 12-weeks post examinations to compare knee valgus during running.
The overall purpose of this study is to quantify the effect and retention of one-week training of falling techniques on landing biomechanics associated with anterior cruciate ligament (ACL) loading compared to soft-landing techniques in young recreational athletes. The secondary purpose is to assess the safety of the training program. Aim 1: To quantify the effect of one-week training of falling techniques on landing biomechanics during forward, lateral, vertical, and diagonal landings compared to soft-landing techniques. We hypothesize that falling techniques will result in increased knee flexion angles and decreased landing forces, knee abduction and internal rotation angles, and knee moments for all landing directions compared to soft-landing techniques immediately after the training. Aim 2: To assess the retention effects of the falling techniques on landing biomechanics compared to soft landings. We hypothesize that the effects of falling techniques on ACL loading variables will be more highly retained compared to soft-landing techniques two weeks after the training. Aim 3: To identify the safety of the training program. We hypothesize that participants can complete the training without suffering minor, moderate, or major injuries, while occasional minor bruises might be observed.
Athletic injury can result in decreased athletic performance or removal from sport participation. There may also be psychological and financial impacts of athletic injury. Additionally, there can be long-term consequences, such as increased risk of subsequent injury or arthritis. Therefore, determining ways to prevent athletic injury from occurring is critical. Movement quality during sport is related to injury risk. Athletes who move poorly are generally at increased risk of injury compared to athletes who move well. Movement quality can be improved through exercise-based injury prevention training, thereby decreasing injury risk. This purposed of this study is to evaluate movement quality multiple times over the course of an athletic season in collegiate athletes who perform injury prevention training. The hypothesis is that movement quality will improve over the course of an athletic season.
The purpose of this CRT study is to compare clinical and functional outcomes of three graft types ( Quadriceps tendon with bone versus Hamstring tendon versus Quadriceps tendon without bone) for reconstration of anterior cruciate ligament among football players.
