Filter by:The term proprioception was first introduced by Sherrington in 1906, who described it as a type of feedback from the limbs to the central nervous system. Based on the early descriptions by Sherrington and others, the contemporary terms of joint position sense (JPS), kinaesthesia (perception of active and passive motion), and sense of tension or force sense are considered sub modalities of proprioception. For the extremity joints, goniometers (universal, bubble, digital) can also be used to measure active JPS. Depending on the device used and the extremity joint measured, reliability and measurement error of active movement goniometry can range widely and this should be carefully considered if goniometry is used to measure active JPS of extremity joints. Kinesthesia, can be measured by calculating the passive motion detection threshold of individuals. The force sense (FS), commonly assessed using force reproduction, has also been used as a measure of proprioception. Assessing force reproduction by limb matching involves the use of a reference force, usually determined as a percentage of a Maximal Voluntary Isometric Contraction (MVIC), and attempting to replicate that force. Proprioception can be decreased in those who suffer from knee injury. Because patients with severe degenerative joint disease often require total knee arthroplasty to relieve pain, improve stability, and restore function. Due to problems such as oedema, immobilization and subjective pain after surgery, it is difficult to evaluate proprioception with joint repositioning method. In such cases, the assessment of FS could be of particular interest in the knee region. FS can also be measured by the accuracy of reproducing a specific target force. For example, the pressure biofeedback device (PBD) used for assessing the cranio-cervical flexion test could be considered a method of assessing force sense in the cervical spine. The ability to hold steadily or the accuracy in achieving and maintaining a desired pressure can be used. However, for the knee region, there is no method to measure the force sense via a device that can be used in clinical practice. The aim of this study was to establish a method for measuring FS that could be applied quickly and practically in the clinic, and to correlate the outcomes with surface electromyographic (EMG) muscle activation levels from M. Quadriceps femoris to demonstrate the applicability and objectivity of this method.
The purpose of this study is to determine the sensitivity of a wearable sensor to detect changes in knee joint loading using an experimental knee joint effusion as a model for a common clinical physiological alteration in joint status. The rationale for this project is that it will establish the efficacy of an inexpensive, clinically, and publicly available device that can detect changes in biomechanical loading due to acute physiologic change in joint status. The study will utilize a cross-sectional cohort study design and will seek to enroll 25 male and female healthy adult participants (18-35 yo). Participants will report to the laboratory for three total sessions (Session 1: informed consent and task familiarization; Session 2: testing; Session 3: knee joint status assessment). The primary outcomes of interest include lower extremity thigh and shank acceleration and velocity data (wearable sensor data), lower extermity 3D kinematics and kinetics (motion capture data), and lower extremity muscle function (EMG data) during walking gait, as well as functional balance and patient-reported subjective outcomes. Data will be analyzed by calculating change scores from the pre- to post-experimental effusion outcome measure testing. Paired-samples t-tests and Cohen's d effect sizes will be used to assess changed in wearable sensor data from pre- to post-experimental effusion. Correlation statistics will be used to determine if there are association between the motion capture and wearable sensor data. The potential risks associated with an experimental joint effusion will be addressed by maintaining appropriate sterile conditions and having the participant check-in with the PI (licensed healthcare provider) at 48 hours following testing session.
The goal of this study is to evaluate the efficacy, safety and performance of the Episealer® device in a sample size of 30 patients and on the long term (10 years follow-up).
Frequent sports events causing more injuries in athletes causing decline in their performance. Injuries around knee joint are common. Strength training of hamstring and quadriceps are effective tool in rehabilitation. The multi-speeds and multi-angles strength training plans were used to see the effects on symptoms and performance in athletes.
To evaluate the clinical safety and obtain preliminary effectiveness data for OrthoPure™ XT device in a small group of US patients at 12 and 24 months. The clinical experience obtained from this study will be used to develop a pivotal study for follow up in a larger patient population.
The purpose of this study is to investigate effects of timing of surgery (early vs. delayed) and timing of post-operative rehabilitation (early vs. delayed) for the treatment of military personnel and civilians that sustain a multiple ligament knee injury. To achieve this overall objective of this project, we will conduct two parallel randomized clinical trials. For the first study we will randomize individuals to timing of surgery and timing of post-operative rehabilitation. We hypothesize that early surgery, early rehabilitation and the combination of early surgery with early rehabilitation will lead to an earlier and more complete return to pre-injury military duty, work and sports and better patient-reported physical function. In the second study, those whose timing of surgery can not be randomized, will be only randomized to early or delayed rehabilitation. For this study, we hypothesize that early rehabilitation will lead to an earlier and more complete return to pre-injury military duty, work and sports activity and better patient-reported physical function.
The Center for Disease Control has labeled the opioid prescription drug crisis an "epidemic" in the United States and recently this epidemic has been named a public health emergency. Various medical and surgical societies have begun to release general opioid prescribing guidelines for providers addressing acute pain, but these do not highlight the patient perspective or experience. Identifying an acceptable opioid dose and duration has remained a challenge and is a nuanced process. Though policy and provider driven changes may begin to augment practice, these avenues may miss a crucial perspective; the patient's.
The purpose of this study is to examine the effectiveness of telehealth via video feedback to transition rear foot strike runners to non-heel strike runner following a lower extremity injury. Telehealth re-education gait training is much cheaper than in-clinic retraining sessions with a medical provider and could be much more widely used by both consumers and researchers as a training aid, a way to help alter running form, prevent running injuries and be used as a tool for use in the rehabilitation of running related injuries.
The aims of the project are to 1) evaluate different aspects of muscle function and its role as a potential risk and/or protective factor for traumatic knee injury in youth female athletes; 2) develop and evaluate a battery of muscle function tests, easily used and requiring minimal equipment, to be applied as an on-the-field screening tool to detect muscle function deficiencies and monitoring youth female athletes at high risk of traumatic knee injury. A prospective cohort design will be used, including approximately 100 female athletes (age 15-19) from Swedish senior sports high schools who are involved in high risk sports (soccer, handball, floorball and basket). A test battery for muscle function has been developed consisting of 11 tests that previously have been used for the assessment of muscle function. The tests will be instructed and supervised by educated test leaders. Measurements will take place at the athletes' school and carried out during the first semester (autumn 2017 and 2018). Data on injury surveillance and exposure (hours of match and training participation) will be collected prospectively over two years using a web-designed registration form. All athletes will on a weekly basis report their hours of training, minutes of match play and all time-loss injuries occurring during sport activity. Details on injury mechanism and diagnosis will be collected by each school's medical staff. The present study will contribute new knowledge on the role of muscle function and develop and evaluate a battery of muscle function tests to be used as an on-the-field screening tool for monitoring youth female athletes at high risk of traumatic knee injury.
Knee MRI is difficult for patients to understand as the image offers a single plane image. Accordingly,investigators sought to transfer the MRI image to 3-dimensional virtual reality system by Mesh rendering technique.
