View clinical trials related to Lower Extremity Problem.
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 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 collect baseline data from a normative population of adolescents who participate in organized "land-based" sports, that gender and age matches some of the population of patients expected to be treated at Mary Bridge Children's Therapy Services, MultiCare affiliated therapy centers, and Mary Bridge Specialty Clinics who will be seen in the Research and Movement Lab. This project will recruit 40 patients between the ages of 13-25 years old. Non-invasive measurements of movement patterns will be collected during common sport-related activities over a single data collection session.
Based on the development of new tools, including drug coated balloon, paclitaxel eluting stent, interwoven stents, debulking tools, More and more acute or subacute thromboembolic occlusions of lower extremity included stage IIb were treated with endovascular procedures. Most guidelines suggests only stage I and stage IIa lesions are suitable for endovascular treatments. Therefore, a well-designed real-world study that track the safety and clinical relevant outcomes, are required to determine the optimal therapies for patients with acute or subacute thromboembolic occlusions of lower extremity.
Individuals living with Transfemoral Amputation, enrolled equally at the Veterans Affairs New York Harbor Healthcare System (VANYHHS) and Walter Reed National Military Medical Center (WRNMMC), will be fit with a powered ankle-foot prosthesis. All subjects will undergo a full gait analysis, functional measures, neurocognitive/cognitive, and pain assessment at baseline utilizing their current passive prosthesis. Subjects will then be randomly assigned into 2 equal groups: Powered device with an 8-session intensive, device-specific PT intervention (Group A); or powered device with current standard of practice (Group B), with includes basic device education, but no PT intervention. Subjects in Group A will undergo a 4-week PT-based intervention, which will isolate the contribution of device specific effects from rehabilitation effects. Group B will receive the current standard of practice, which does not include any formal rehabilitation. All users will undergo a full gait analysis, functional measures, neurocognitive/cognitive, and pain assessment after 4- and 8-weeks of use.
