A randomized controlled trial investigating the effects of a 4-week ankle rehabilitation program on high school athletes with chronic ankle instability.
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.
After an initial ankle sprain, Chronic Ankle Instability is one of the most common residual symptoms which include pain, swelling, recurrent sprain, episodes of ankle joint "giving away" or decreased function. Recently, Whole Body Vibration (WBV) training has been introduced as a preventive and rehabilitative tool. It can be hypothesized that WBV on unstable surfaces might enhance neuromuscular control. Therefore, the aim of this study was to investigate the effects of a 6-week WBV training on an unstable surface on body composition, balance, strength and reflex and muscle activity of ankle muscles in recreational athletes with CAI.
This is a randomized controlled trial (RCT) regarding the conservative treatment of chronic ankle instability (CAI) with an impairment based rehabilitation program. Individuals with CAI have deficits in neuromuscular control and altered gait patterns. Ankle destabilization shoes are used clinically and may improve neuromuscular control by increasing lower extremity muscle activation, which may improve gait patterns. The investigators' purpose is to determine whether a 4-week rehabilitation program that includes ankle destabilization shoes (experimental) has beneficial effects on self-reported function and ankle gait kinematics compared to traditional rehabilitation without destabilization shoes (control) in CAI patients. In addition, the investigators will compare ankle strength and balance between CAI patients and healthy individuals with no history of ankle injury prior to the 4-week rehabilitation. The investigators hypothesize the experimental group will have greater improvement in self-reported function and frontal and sagittal plane kinematics during walking compared to the control group. In addition, the investigators hypothesize that patients with CAI will have a decrease in ankle strength and balance when compared to healthy individuals. The design is a single-blinded randomized controlled trial. Forty CAI patients will complete baseline self-reported function questionnaires and walking gait trials and then be randomized into control and experimental groups. Both groups will complete 4-weeks of supervised rehabilitation with or without destabilization shoes and then repeat the questionnaires and walking trials.
Untreated ankle sprains often remain symptomatic and may end in chronic instability. The aim of our study is to quantify the stabilizing effect of different devices. Through the use of a foot measurement model in 3D motion analysis the influence of the devices with respect to a mechanical effect is examined by means of different tests. The dynamic postural control is quantified. The hypothesis was that the devices would stabilize differently the foot segments.
Untreated ankle sprains often remain symptomatic and may end in chronic instability. The aim of our study is to quantify the stabilizing effect of different devices. Through the combined use of the 3D motion analysis and the surface electromyography, the influence of the devices with respect to a mechanical effect and to an influence on the neuromuscular control are examined. The tests will simulate situations with a higher risk of injury. In the experimental set-up, an element of surprise will be integrated in order to analyze any muscular compensation mechanisms.
The main goal of this study is to evaluate the effect of taping on postural control during dynamic exercises. 30 subjects with Chronic ankle instability (CAI) will be included in the study. Several questionnaires regarding anthropometric data, medical history, activity level and functional status will be filled in by the participants. Postural control will be measured using a force plate and an optoelectronic system to capture lower limb kinematics. Subjects will be asked to perform a forward hop, sideward hop and a vertical drop, and they have to maintain their balance for 10 seconds after landing. 5 good trials of each movement will be captured. Subjects with CAI will perform these exercises with and without tape. Hypothesis is that subjects with CAI that tape will enhance postural control.
The purpose of this study is to determine the effect of 3 types of sensory-targeted rehabilitation interventions on subjective and objective measures of function for those with chronic ankle instability. The investigators hypothesize that subjective and objective measures of function including self-reported disability, balance, and range of motion will improve after 2-weeks of sensory-targeted interventions.
