Filter by:Investigators designed this prospective cohort study to compare the clinical outcomes of modified Broström operation and anatomical reconstruction for the treatment of CLAI and GJL.
The aim of this study was to analyse and compare the speed and power parameters in bench press training in different degrees of instability: 1) stable (PBE), 2) with asymmetric load (PBA), 3) with oscillating load (PBO), 4) on fitball (PBF) and 5) on bosu (PBB). For this purpose, 20 male subjects (10 trained and 10 untrained) with specific experience in training under unstable conditions were evaluated with respect to mean propulsive velocity (MPV), maximum velocity (MV) and power (POT) with different types of external load: low load (40% of 1RM), medium load (60% of 1RM) and high load (80% of 1RM) in each condition.
Study Design: Evaluation of the psychometric properties of a translated, culturally adapted questionnaire. Objective: Translating, culturally adapting, and validating the Italian version of the Cumberland Ankle Instability Tool (CAIT-I), allowing its use with Italian-speaking population to monitor both state of health and functional limitation deriving from ankle instability problems, in order to evaluate the degree of severity, without using the comparison with the opposite limb. Summary of Background Data: Lateral ankle sprain is the most common injury during sports activity, often cause of disability and of numerous complications following repeated episodes, including chronic ankle instability (CAI), which affects 32% to 74% of the aforementioned cases. Growing attention is devoted to standardized outcome measures to improve interventions for injured population. A translated form of the Cumberland Ankle Instability Tool (CAIT), a simple and specific tool for diagnosing chronic lateral ankle instability with excellent psychometric characteristics of both reliability and validity, has never been validated within the Italian speaking population.
The objective of the study is to evaluate the postural control and proprioception before and after external capsulo-ligament reconstruction for ankle instability.
The aim of this study is to identify factors responsible for recurrent shoulder instability in children. Shoulder instability, i.e. complete or partial dislocation of the shoulder joint, is common in children, resulting in pain and disability. Recurrent instability can damage the shoulder joint resulting in the premature development of arthritis. Rehabilitation approaches are preferred over surgical methods for the growing child e.g. physiotherapy to restore movement and prevent further instability. Existing rehabilitation procedures are based on addressing factors assumed to be responsible for instability e.g. physiotherapists may try to increase shoulder stability by building up the shoulder muscles to compensate for the damaged ligaments. It is evident however that the mechanisms of shoulder instability are not well understood, as failure rates for physiotherapy are high, with 70% - 90% of children continuing to suffer recurrent instability. This is an observational, cross-sectional study of children (aged 8 to 18) presenting with shoulder instability of any origin, traumatic or atraumatic (n=15) and an age-matched sample (n=15) with no history of shoulder problems. Muscle activity and movement pattern differences will be measured using non-invasive 3D motion capture and surface electromyography, to identify factors responsible for instability. Only a single visit to the site will be required (The Orthotic Research & Locomotor Assessment Unit (ORLAU) based at The Robert Jones & Agnes Hunt Orthopaedic Hospital NHS Foundation Trust in Oswestry.). If investigators better understand the mechanisms associated with instability, physiotherapy interventions to reduce dislocations and disability can be better targeted. If specific patterns of activity associated with instability are identified, these could be addressed through personalised and improved exercise prescription and rehabilitation. Additionally, causes of instability for which physiotherapy may not be appropriate may be identified, therefore ensuring patients are referred to the correct service in a timely manner, improving patient outcomes and allocating physiotherapy resources more appropriately. Participants will be recruited from musculoskeletal/orthopaedic outpatient clinics. This study is funded by the Private Physiotherapy Education Foundation.
Prospective, multicenter, observational, comparative clinical trial on the equivalence of two different OrthoPilot® navigation system generations applied for computer-assisted total knee arthroplasty
The scientific justification is to fulfill post-market clinical requirements in order to support re-certification of the CE-Mark for this marketed product and to look into safety and efficacy.
Background: Ankle sprains are among the most prevalent lesions in primary care. A substantial number of these ligament lesions will develop ankle instability and require a surgical procedure. The Brostrom-Gould technique is the standard surgical approach for this condition, providing excellent results over the years. Thru the last decades, the arthroscopic Brostrom has gain popularity and support by several studies. Yet, there is no consensus regarding the best procedure to treat ankle instability nowadays. Hypothesis: The arthroscopic Brostrom technique will present better levels of pain and function when compared to the standard open approach. Design: blinded, in parallel groups, multicentric, randomized, clinical trial. Materials and Methods: 98 patients with a diagnosis of chronic ankle instability, referred from primary or secondary health care services, will be assessed and enrolled in this study. Participants will be divided in two groups (randomized by sequentially numbered identical envelopes, which will be administered serially to participants), one containing the open Brostrom repair technique and the other comprehending the arthroscopic Brostrom approach. The assessments will occur in 3, 6, 12, 24 and 48 weeks. Patients will be evaluated primarily by complications and secondarily the Cumberland Ankle Instability Tool (CAIT), American Orthopedic Foot and Ankle Society (AOFAS), the Visual Analogue Scale (VAS), the Foot Function Index (FFI) and the 36 Item Short Form Health Survey (SF-36). The investigators will use Comparison of Two Proportions via relative frequency analysis, the Pearson Correlation the Chi-Square test and the ANOVA for statistical analyses. Discussion: This study intends to establish if the arthroscopic Brostrom technique can produce excellent and reliable results when treating chronic ankle instability. A shorter surgical time, a better cosmetic appearance and a smaller soft tissue injury would support the choice for this procedure if the outcomes could be compared to the open approach.
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.
