Filter by:This study aims at investigating the validity and reliability of a smartphone application "MyAnkle: in assessing the balance component of postural control in patients with chronic ankle instability (CAI).
This study evaluates the efficacy of gait retraining with biofeedback in the treatment of neuromusculoskeletal symptoms in patients with Joint Hypermobility Syndrome/Hypermobile Ehlers Danlos Syndrome. Half of participants will participate in a gait retraining program, while the other half will continue standard care.
A randomized controlled trial investigating the effects of a 4-week ankle rehabilitation program on high school athletes with chronic ankle instability.
The goal of this study is evaluate the effect of uni-axial versus multidirectional balance training on muscle reaction time in subjects with chronic ankle instability. Muscle reaction time is measured on a trapdoor simulating an inversion sprain before and after a 6 week lasting balance training protocol.
The arthroscopic subscapular sling procedure is a new technique for shoulder stabilization, which has been developed in human cadaveric studies by Klungsøyr et al, but has yet to be tested clinically. The procedure stabilizes the shoulder by using a semitendinosus graft that makes a new labrum and a sling around the subscapular tendon. Extensive biomechanical robotic testing of the procedure shows significant less translation and thus better stability of the humeral head with the sling compared to a normal Bankart repair. The investigators consider the biomechanical results after robotic testing sufficient to advocate a planned pilot study in humans. In this pilot study the clinical and radiological results of the sling will be investigated in a small number of cases. The safety of the subscapular sling procedure will be assessed. This studies results are expected to be a further step towards implementation of the sling procedure as a surgical option for shoulder instability.
ABSTRACT: Injury associated with sport and recreation is a leading reason for physical activity cessation, which is linked with significant long-term negative consequences. Lateral ankle sprains are the most common injuries associated with physical activity and at least 40% of individuals who sprain their ankle will go on to develop chronic ankle instability (CAI), a multifaceted condition linked with life-long residual symptoms and post-traumatic ankle osteoarthritis. Our long term goal is to develop intervention strategies to decrease disability associated with acute and chronic ankle injury and prevent posttraumatic ankle osteoarthritis. Conventional rehabilitation strategies, are only moderately successful because they ignore the full spectrum of residual symptoms associated with CAI. Manual therapies such as ankle joint mobilizations and plantar massage target sensory pathways not addressed by conventional treatments and have been shown to improve patient-reported outcomes, dorsiflexion range of motion, and postural control in CAI patients. While these early results are promising, the underlying neuromuscular mechanisms of these manual therapies remain unknown. Therefore the objective of this R21 proposal is to determine the neuromuscular mechanisms underlying the improvements observed following independent ankle joint mobilization and plantar massage interventions in CAI patients. To comprehensively evaluate the neuromuscular mechanisms of the experimental treatments, baseline assessments of peripheral (ankle joint proprioception, light-touch detection thresholds, spinal (H-Reflex of the soleus and fibularis longus), and supraspinal mechanisms (cortical activation, cortical excitability, and cortical mapping, sensory organization) will be assessed. Participants will then be randomly assigned to receive ankle joint mobilizations (n=20), plantar massage (n=20), or a control intervention (n=20) which will consist of 6, 5-minute treatments over 2-weeks. Post-intervention assessments will be completed within 48-hours of the final treatment session. Separate ANOVAs will assess the effects of treatment group (ankle joint mobilization, plantar massage, control) and time (baseline, post-treatment) on peripheral, spinal, and supraspinal neuromuscular mechanisms in CAI participants. Associations among neuromuscular mechanisms and secondary measures (biomechanics and postural control) will also be assessed. The results of this investigation will elucidate multifaceted mechanisms of novel and effective manual therapies (ankle joint mobilizations and plantar massage) in those with CAI.
Patients who received a total knee endoprosthesis BPK-S Integration between 2011 and 2013 will be invited to participate in this PMCF study provided sufficient source data documentation is available regarding preoperative, intraoperative and early postoperative follow-up assessments. Only patients providing written informed consent prior to any study data collection can take part in the study. Preoperative, intraoperative and early postoperative data (3 months, 1 year and 2 years after implantation) will be collected retrospectively. Additional long-term follow-up of one visit (year 7 after implantation) will be documented prospectively. Only parameters assessed in clinical standard care for follow-up (implant control) visits will be collected for this PMCF study. Radiological assessment of the implanted prosthesis will only be conducted if medically indicated according to the investigator. No additional study related assessment will be performed. Only anonymized data will be used in this observational study to protect patient privacy. No personally identifiable information will be collected.
Prospective Post-Market Clinical Follow up study according to MEDDEV 2.12/2 rev2 of the European Union. Patients receiving the primary knee implant BPK-S UC as primary implant in either variant ceramic or CoCr (metal) are eligible for the study and will be followed up for 5 years after implantation or until revision of the prosthesis, whichever occurs first. Demographic data will be collected together with data regarding safety and benefit at defined timepoints (preoperative, intraoperative and at 3 months, 1 year, 2 years and 5 years after implantation). Patients will be divided in 2 cohorts (ceramic and metal) and stratified by age.
A post market, non-randomized, multi-center, open-label,clinical study using survivorship to study the safety and efficacy of the Integra® TITAN™ Total Shoulder System 1.0 (TAS) when used for total shoulder arthroplasty.
This study aims to evaluate the effect of platelet-rich plasma (PRP) on chronic lateral ankle instability by comparing the imaging and clinical outcomes between patients receiving PRP and those receiving whole blood during the modified Broström-Gould procedure.
