Filter by:The lower extremity consists of segments that can be affected by the relative position of each other. Deviation of one segment from its normal alignment in the lower extremity also affects the alignment of other segments. The hip joint can affect the frontal plane alignment from proximal to distal, while the foot and ankle complex can also affect it from distal to proximal. Increased subtalar joint pronation in the kinetic chain from distal to proximal; is associated with decreased dorsiflexion angle and increased frontal plane projection angle. It has been shown that ankle dorsiflexion limitation causes changes in the biomechanics and kinematics of landing after jumping, but no study examining the effect of foot pronation on jump tests has been found in the literature. Since the foot is located at the most distal point and acts as a support base for the kinematic chain, the smallest dynamic change in the foot affects the balance of the whole body. Due to foot pronation, changes in the sole contact surface may make it difficult for the foot to adapt to the ground, balance and postural stabilization may be adversely affected, and an increase in the workload of the muscles around the joint may be observed. In another study, it is mentioned that there is limited evidence about the effect of foot posture on postural stability. Although there are studies in the literature examining the effects of subtalar joint pronation on lower extremity alignment and postural stability, studies need to examine the effects of different subtalar joint pronation amounts on lower extremity alignment, jumping performance, and postural stability. Our study will contribute to the literature with this aspect.
The purpose of this investigation is to compare the effects of a combined hip activation and core stabilization training home exercise program (HEP) versus a hip activation training HEP alone on lower extremity (LE) frontal plane mechanics in healthy individuals. Specific Aim 1: To determine whether between- and/or within-group differences exist on the Forward Step-Down test (FSDT) when comparing a combined hip activation and core stabilization training HEP as compared to a hip activation training HEP. Specific Aim 2: To determine whether between- and/or within-group differences exist on the peak external knee abduction moment when comparing a combined hip activation and core stabilization training HEP to a hip activation training HEP. Specific Aim 3: To determine whether between- and/or within-group differences exist on gluteal and core muscle surface electromyography (sEMG) when comparing a combined hip activation and core stabilization training HEP to a hip activation training HEP. Specific Aim 4: To determine whether a dose-response relationship exists between HEP compliance and change on the FSDT, peak external knee abduction moment, and sEMG.
In this pilot study the investigators are testing whether an injury prevention program will help improve quality of movement and decrease number of injuries in collegiate women's lacrosse athletes. The primary purpose is to determine whether an injury prevention program including individualized movement instruction along with an educational program is better than an educational program alone for improving movements that can increase risk of injury and decreasing number of injuries. The investigators will recruit women's lacrosse athletes from the San Diego State University women's lacrosse team. Enrolled participants will be divided up into two groups of 10 individuals. Both groups will participate in an injury prevention educational program including a lecture component with pictures and videos, and a practice component in which athletes will be provided with group instruction on how to perform the activities and then will have an opportunity to practice all activities. In addition to the educational program, athletes in the individualized movement instruction group will be provided individualized feedback on their movements when performing activities from the injury prevention program during 3 sessions throughout the season. The primary outcomes that will be evaluated include lower body movement during a jumping and balance task as measured using a 3D motion capture system. The investigators hypothesize that participants who receive the individualized feedback in addition to the education program will display greater improvements in movements that increase injury risk when compare to the education only intervention group.
Different musculoskeletal conditions affect people all over the world and were considered by the WHO to be the leading cause of disability in 4 out of 6 regions in 2017, with an increase in the associated burden and impact on society expected in the coming years. The knee is a complex joint, vulnerable to various types of injury. The most common are ligament, meniscus and cartilage injuries of different etiologies. After surgery, as a result of the reflex inhibition of motor neurons and immobilization, there is rapid atrophy and weakness in the different associated muscles, affecting proprioception, muscle strength and extension, clearly compromising health-related quality of life. Through partnership and collaboration between health institutions and academia, the rehabilitation program will take place on an outpatient basis in a supervised manner, allowing its effectiveness to be assessed using Patient-Reported Outcome Measures. These instruments are a rapidly developing topic and it is essential to understand whether the Patient-Reported Outcome Measures used are sufficient to measure the results perceived by patients with lower limb pathology who take part in rehabilitation programs. The different Patient-Reported Outcome Measures will be applied before and after the program.
The percentage of loss time claims receiving Loss of Earnings benefits at 3 months has continued to rise amongst injured workers in Ontario despite the Workplace Safety and Insurance Board (WSIB) approach of "Better at Work". The primary health services to address loss time claims associated with musculoskeletal injuries include the evidenced-based programs of care, occupational health assessment program and musculoskeletal specialty programs, however, these are set to be revised and relaunched in Q1 2023. Across treatment protocols there are challenges that, at least in part, appear to contribute to the increasing percentage of workers on full loss of earnings at 3 months include (1) inconsistent early identification of workers who should be triaged to various health services and (2) reliable determination of the optimal timing of referral to the most targeted care to enable a safe and sustainable return to work. The investigators aim to develop and evaluate a predictive assessment model to triage workers to the best service within the first 8 weeks of their claim to increase the rate of early return to work, with the long-term goal that the triage protocol becomes part of a person-centric protocol that reduces the duration of work-related disability. The investigators will develop and evaluate an assessment protocol for injured workers that enter any of the musculoskeletal-specific WSIB programs of care, which have been consolidated into a single program as of 2023. This study will be a prospective inception cohort design using data collected from injured workers receiving WSIB musculoskeletal programs of care services at CBI Health clinics in Ontario Canada. Worker data will be collected at intake to the program of care service and again approximately four and eight weeks after intake (or earlier if a worker completes the program of care). The investigators will complete data analysis in three steps including descriptive and bivariate associations, Maximum Likelihood-based Latent Profile Analysis, and evaluation of results against successful work outcomes and secondary outcomes. Qualitative data will be mined for alternative indicators of recovery / non-recovery. The study recruitment goal is 300 - 350 workers with complete follow-up within a 2-year period.

The objective of this study is to Determine Comparative Effects of Plyometric and Isotonic Strengthening Exercises on Speed, Agility and balance of lower extremity among field Tennis Players
The ultimate goal of treating children with lower extremity differences is to improve quality of life, optimize function, and maximize participation by addressing the physical, social, and psychological effects of lower extremity differences. In the pediatric field, research has focused on the Body Functions and Structures area of the ICF framework, such as radiographic measurements of limb alignment and length, postoperative complications, and recovery time. Priority targets for children/parents are better captured in the Activity and Participation areas of the ICF framework. Developed in Canada, the Gait Outcomes Assessment List (GOAL)was created to evaluate outcomes for gait-related interventions for children with cerebral palsy based on a wide range of children's and parents' goals. It was also developed for other childhood conditions associated with lower extremity disorders. The present study aimed to determine the Turkish cultural adaptation, validity, and reliability of the "Gait Outcomes Assessment List for Children With Lower-Limb Difference Parent Version/ Child Version" in Pediatric Rheumatologic Diseases.
Although spasticity, contractures and muscle weakness in children with CP are disorders that can be observed more easily and are more focused and given more importance in evaluation and treatment approaches; Inadequate or loss of selective motor control negatively affects motor functions to a greater extent. It is very important to reveal the causes and consequences of selective motor disability in children with spastic cerebral palsy, in terms of creating effective treatment plans. The number of patients to participate in the study was determined as 100. The study will be carried out in Hatay Mustafa Kemal University Research and Application Hospital, Department of Pediatrics. In our study, demographic information will be filled in, and lower extremity selective control assessment scale (SCALE) for lower extremity, upper extremity selective control scale (SCUES) for upper extremity, and sensory assessment (touch, two-point discrimination and proprioceptive sensory assessment) will be performed on the patients who accepted the study.
The purpose of this study is to determine if activation training of the hip musculature affects muscle activation and frontal plane mechanics in healthy individuals. Specific Aim 1: Determine whether performance on the forward step-down test (FSDT) changes after an eight-week home exercise program (HEP) focused on hip musculature activation in healthy individuals. Specific Aim 2: Determine whether surface electromyography (sEMG) hip musculature changes following an eight-week HEP focused on hip musculature activation in healthy individuals. Specific Aim 3: Determine whether a dose-response relationship exists between compliance on the HEP and changes in FSDT scores in healthy individuals. Specific Aim 4: Determine whether a dose-response relationship exists between compliance on the HEP and sEMG changes in hip musculature activation in healthy individuals.
After dividing the patients into two groups, sedation is performed with propofol and remimazolam, respectively, after spinal anesthesia. Compare the patient's body temperature change after surgery.
