Anterior cruciate ligament graft geometry has previously been linked to abnormal tibiofemoral kinematics, suggesting this parameter may be important in restoring normative cartilage loading. However, the relationship between graft geometry and cartilage contact is unknow. (...) Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=155885

Titre : Clinic-Based Assessment of Weight-Bearing Asymmetry During Squatting in People With Anterior Cruciate Ligament Reconstruction Using Nintendo Wii Balance Boards Type de document : Article Auteurs : Ross A.

Gonarthrose ; Rééducation et réadaptationMots-clés : Anterior Cruciate Ligament Ligament croisé antérieur Anterior cruciate ligament reconstruction Reconstruction du ligament croisé antérieur Osteoarthritis Knee Résumé : Objective
To use low-cost Nintendo Wii Balance Boards (NWBB) to assess weight-bearing asymmetry (WBA) in people who have undergone anterior cruciate ligament reconstruction (ACLR), and to compare their results with a matched control group.
Design
Quantitative clinical study using a cross-sectional design.
Setting
Orthopedic clinic of a private hospital.
Participants
ACLR participants (n=41; mean age + SD, 26.0+9.8y; current Cincinnati sports activity level, 75.3+19.8) performed testing in conjunction with their routine 6- or 12-month clinical follow-up, and a control group (n=41) was matched for age, height, body mass, and physical activity level.
Interventions
Participants performed double-limb squats while standing on 2 NWBBs, 1 under each foot.
Main Outcome Measures
The WBA variables mean mass difference as a percentage of body mass, time favoring a single limb by >5% body mass, absolute symmetry index, and symmetry index relative to the operated or matched control limb were derived. Mann-Whitney U tests were performed to assess between-group differences.
Results
Significant (P<.05 increases in asymmetry the aclr group were found for all outcome measures except symmetry index relative to operated limb.> Conclusions
People who have undergone ACLR are likely to possess WBA during squats, and this can be assessed using low-cost NWBBs in a clinical setting. Interestingly, the observed asymmetry was not specific to the surgical limb. Future research is needed to assess the relationship between WBA early in the rehabilitation process and long-term outcomes.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=https://www.sciencedirect.com/journal/a [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=119016

Titre : Coordination stability between the legs is reduced after anterior cruciate ligament reconstruction Type de document : Article Auteurs : Cortney N. Armitano ; Steven Morrison ; Daniel M. Russell Article en page(s) : p. 28-33 Langues : Anglais (eng) Mots-clés : Anterior Cruciate Ligament Reconstruction Reconstruction du ligament croisé antérieur Gait Démarche Motor Skills Disorders Troubles des habiletés motrices Résumé : Background
The study was designed to examine coordination differences in walking between individuals with an anterior cruciate ligament reconstruction compared with healthy matched controls. Predictions from the extended Haken, Kelso, and Bunz coupled oscillator model were tested in these populations.
Methods
Seventeen persons with anterior cruciate ligament reconstruction and 17 matched controls participated in the study. Sagittal plane angular knee displacement was recorded using electrogoniometers over the lateral right and left knee joints while participants walked at five walking speeds overground. Coordination pattern and stability between the knees were quantified by mean and standard deviation of relative phase, respectively.
Findings
Mean relative phase was not influenced by walking speed or group. For both groups, coordination stability was maximal when individual's walked at their preferred gait speed. However, the anterior cruciate ligament reconstruction group demonstrated reduced coordination stability compared with healthy controls across the five speeds. Multiple regression analyses found that people with anterior cruciate ligament reconstruction who deviated more from antiphase coordination had decreased coordination stability.
Interpretation
Anterior cruciate ligament reconstruction results in decreased coordination stability, indicative of reduced coupling strength between the legs. This change in gait coordination, which has not previously been found in the literature, may contribute to the increased rate of re-injury and degeneration in individuals who have had this reconstructive surgery. Application of a motor control model enhances our understanding of the influence of an injury on coordination during gait.Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=155908

Titre : Effects of localized vibration on knee joint position sense in individuals with anterior cruciate ligament reconstruction Type de document : Article Auteurs : Takashi Nagai ; Nathaniel A. Bates ; Timothy E. Hewett Article en page(s) : p. 40-44 Langues : Anglais (eng) Descripteurs : HE Vinci
Proprioception ; VibrationMots-clés : Anterior Cruciate Ligament Ligament croisé antérieur Anterior Cruciate Ligament Reconstruction Reconstruction du ligament croisé antérieur Muscle Spindles Fuseaux neuromusculaires Résumé : Background
Anterior cruciate ligament injury can disrupt one's mechanoreceptors and result in decreased proprioception such as joint position sense and ultimately altered motor function. The application of localized vibration has been used to investigate the integrity of the sensorimotor system and the mechanisms of quadriceps function after anterior cruciate ligament injury and reconstruction. The purpose of the study is to evaluate joint position sense with and without vibration and compare among anterior cruciate ligament reconstructed, contralateral, and control limbs.
Methods
Fourteen subjects with anterior cruciate ligament reconstruction (8 males and 6 females) and fourteen control subjects (7 males and 7 females) participated in the study. Subjects sat on an isokinetic dynamometer chair with localized vibration strapped on the quadriceps tendon while visual and auditory cues were removed. Subjects were asked to remember an active target position and replicate that position actively. The absolute difference between the target and replicated trial was used as joint position sense. There were three trials at three target positions (15, 45, and 75 degrees of knee flexion) with and without vibration. The order of testing conditions was randomized. One-way analysis of variance or non-parametric equivalent (Kruskal-Wallis test) was used to compare among limbs. Significance was set at P Findings
There were no significant joint position sense differences among anterior cruciate ligament reconstructed, contralateral, and control limbs with or without vibration (P = 0.207–0.914).
Interpretation
There are several potential reasons for the current findings: vibration-induced post effect, locations of vibration, types of vibration, and rehabilitation status. Future studies should expand the current investigation and explore both sensory and motor functions in anterior cruciate ligament reconstructed subjects.Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=155829
