Filter by:A population of patients with chronic ankle instability for whom arthroscopic ligament stabilisation was indicated. Main objective: to use the Raman microspectroscopy technique to characterise the synovial fluid of the unstable ankle in comparison with the synovial fluid of the healthy ankle.
The study will be a randomized clinical trial with the sample size of 26. The study will be conducted at Sports Club Sheikhupura. Subjects will be enrolled according to eligibility criteria. Patients will be divided into two groups, each with 13 patients. Group A will receive SMART training intervention and warm-up exercises, while group B will receive Foot intensive rehabilitation exercises (FIRE) and warm up exercises. The session will be around 45 to 60 min on each patient with three sessions per week on alternate days. A total of Three weeks treatment regime will be given to the patients and assessment of patient's strength (CAIT) and performance (FAAM) will be done at the baseline, after the completion of treatment at three weeks and after six weeks to observe the long-term effects.
Purpose: Chronic ankle instability (CAI), characterized by instances of repetitive sprains and giving way, is a common chronic dysfunction among athletes. Despite well documented evidence showing impaired peripheral sensory and both central and peripheral motor control, little was known regarding how CAI affects somatosensory cortical activation. Traditionally, management of CAI mostly focused on restoration of motor deficits, with less emphasis on sensory pathway deficits. Only few sensory targeted intervention methods including joint mobilization and massage, have been described. However, methods such as joint mobilization provide not only sensory stimulation but also mechanical alignment correction. In addition, these studies showed functional improvement without exploring mechanisms. Therefore we would like to apply for a three year study grant to firstly investigate the effect of CAI on peripheral and central somatosensation and neuromuscular performance; and secondly to examine the immediate effect of sensory-level electrical stimulation on neurophysiological variables and neuromuscular performance; and lastly to determine the short-term effect of intervention (sensory stimulation with exercise, sham stimulation with exercise, and exercise alone) in athletes with CAI. Research design and methods: This is a cross-sectional exploratory and randomized controlled study. For the first year, we plan to recruit 45 young athletes (20-40 years old) with CAI and 15 matched controls to compare the somatosensory evoked potentials (SEPs), corticomuscular coherence (CMC), α- band event-related desynchronization (ERD), proprioception, two point discrimination threshold of the plantar surfaces, muscle activation and reaching distances of the Y balance test. Activity in the sensorimotor cortex will be recorded using a 64-chanel EEG (SAGA 32/64+ for EEG). Muscle activation is measured using an 8-channel electromyography (EMG) system (Noraxon myo METRICS Portable Lab, Noraxon U.S.A.). For the second year, the 45 young adults with CAI will be randomized into the sensory stimulation (TENS) group, the sham stimulation group, or the control group. The TENS group will receive 40 minutes of sensory electrical stimulation, and the sham group will receive 30 seconds of sensory stimulation at the beginning and end of the treatment. The control group will rest for 40 minutes. The assessment items are identical to those in the first year, and will be carried out before and immediately after the intervention. For the third year, the 45 young adults with CAI will be randomized into the exercise with sensory stimulation (EX-TENS) group, exercise with sham stimulation (EX-ss) group, or exercise alone (EX) group. Participants will receive five sessions of intervention (30 minutes neuromuscular training with or without 40 min stimulation) within two weeks and the assessment will be carried out before and after the intervention. Data analysis: Comparisons of all continuous variables are performed using oneway analysis of variance (ANOVA), and repeated measures ANOVA. The significance level is set at 0.05. Significance. Results of this study provide a better understanding for central somatosensory control mechanisms for chronic ankle instability, and help clinicians and trainers to choose the most appropriate training strategy for people with unstable ankles. We plan to present our work in 3-4 international conferences, and publish 2-3 papers in SCI journals in 5 years.
The current study involves a prospective interventional study that primarily intends to compare foot joint loadings of participants with chronic ankle instability (CAI) with those of subjects who recovered after an ankle sprain (LAS copers) and healthy controls during running and more challenging tasks. This study further aims to explore the impact of foot muscle properties and fatigue on the same biomechanical outcomes. Therefore, the investigators will recruit 72 participants (24 per group) aged from 18 to 44 years. Each of them will come only once to the CMAL laboratory (UZ Leuven, Pellenberg).
34 volunteer professional volleyball players with (n=12) and without (n=22) CAI will include in the study. Mulligan ankle taping will apply. Measurements will take before and after the intervention. Muscle tone, stiffness, and elasticity will measure with MyotonPRO hand-held device. The static balance will measure with single leg stance test(SLST) while the eyes-closed, dynamic balance will measure with the Y balance test(YBT). Single leg hopping test(SLHT) will evaluate performance and an active position sense test will use for JPS. During the static and dynamic balance and performance tests, the ankle's confidence will be evaluated with the Visual Analog Scale (VAS). The study aimed to determine the effect of Mulligan fibular taping over the Tibialis Anterior(TA), Peroneus Longus(PL), Gastrocnemius Lateralis(GCL), and Medialis(GCM) muscles on muscle tone, stiffness, elasticity, as well as the performance, joint position sense(JPS), static and dynamic balance in female volleyball players with and without chronic ankle instability(CAI).
This study aims to investigate the clinical effectiveness of PEMF as an adjunct to a program of standard rehabilitation for the treatment of chronic ankle instability. The study objective is to establish whether PEMF plus standard rehabilitation in people with chronic ankle instability compared to standard rehabilitation. This study also investigates the effects of PEMF on pain, functional outcomes, and mechanical and morphological properties of peroneal muscles in chronic ankle instability. Investigators hypothesize that pulsed electromagnetic field therapy is effective in reducing pain, improving functional outcomes, and restoring mechanical and morphological properties. This study is a double-blinded, randomized controlled trial to investigate the clinical effects of pulsed electromagnetic field therapy (PEMF) for chronic ankle instability. Participants will be recruited from the outpatient clinic of the orthopedic and traumatology department at Prince of Wales Hospital. 40 patients aged between 18 to 60 years old with CAI will be invited to join this trial after informed consent. Participants will be randomized to any of the 2 groups: the intervention group (n=20; PEMF (Quantum Tx) treatment), and the control group (n=20; sham treatment with dummy exposure to PEMF). For Chronic Ankle Instability patients: baseline measurements of all self-reported outcomes, functional outcomes, and ultrasound imaging assessments, such as dynamic balance, static balance, single leg hop test, gait evaluation, dorsiflexion range of motion, and eversion muscle strength.
Real-life, observational, monocentric, prospective, longitudinal study, carried out at the European Center for Sports Rehabilitation (CERS), France.
Chronic ankle instability is associated with changes in the nervous system that amount to increased difficulty in activating the stabilizing muscles of the ankle. Neuromuscular Electrical Stimulation involves using electricity to activate those muscles in bursts, and is commonly used to improve muscle function in those with ACL injury. This study will provide 5 treatments over 2 weeks in patients with Chronic Ankle Instability and determine if Electrical Stimulation can change neural excitability, balance, neuromuscular control, and perceived function in these individuals.
Rationale: Lateral ankle ligament injuries may be a result of ankle sprains. In 10-30% of patients with lateral ankle ligament injuries, chronic lateral ankle instability may be present. If conservative treatment fails, instability is treated surgically. Anatomic repair (also known as the Bröstrom procedure) is the current golden standard for surgical treatment of chronic ankle instability. The Bröstrom started out as an open technique and is now also performed arthroscopically. Both approaches are considered standard care and provide good results. Which approach is best, has not yet been researched. In this study it is hypothesized arthroscopic repair provides better functional outcome compared to open repair during short term follow-up. Objective: The main objective of this study is to compare the functional outcome after arthroscopic and open anatomic repair in patients with chronic lateral ankle instability, and secondly to assess ankle stability and ankle Range of Motion (ROM) after arthroscopic and open ligament repair. Study design: A Non-Blinded Prospective Randomized Controlled Trial Study population: All patients willing to participate, from an age of 18 years old, with persisting ankle instability for at least 6 months, eligible for anatomic repair. Intervention: Both groups of patients are surgically treated with anatomic repair of the anterior talofibular ligament (ATFL). One group is treated arthroscopically and the other by the open approach. Main study parameters/endpoints: The primary outcome measure is functional outcome 6 months after surgery measured using the Foot and Ankle Outcome Score. The main study parameter is a difference of ≥10 2 points per FAOS subscale between both treatment groups (Minimal Important Change = 10 points; 2 per subscale).
Chronic ankle instability is a common problem that may follow an ankle sprain. Until a patient has developed chronic ankle instability they are ineligible for surgical treatment although early surgical treatment yields better results compared to surgical treatment of subjects that have experienced recurrent ankle sprains. However, treating all patients with an ankle sprain surgically is not an option due to the high amount of unnecessary invasive interventions. The objective of this study is to identify which patients will develop chronic ankle instability and to develop a model to predict which patients should receive early surgical treatment. In this prospective observational cohort all patients (older than 18 years) that report at the emergency department of the participating hospitals after a lateral ankle sprain, of whom an x-ray is made after positive Ottawa Ankle Rules and on which there is no visible fracture or other pathology. The main study parameter is a significant difference in patient characteristics, foot and ankle configuration and joint pathology between patients who develop chronic ankle instability and patients who do not experience recurrent ankle sprains and restriction during daily live after an initial sprain.
