Changes in transcranial magnetic stimulation outcome measures in response to upper-limb physical training in stroke: A systematic review of randomized controlled trials / Louis-David Beaulieu in Annals of physical and rehabilitation medicine, Vol. 61, n°4 (Juillet 2018)
[article]
Titre : Changes in transcranial magnetic stimulation outcome measures in response to upper-limb physical training in stroke: A systematic review of randomized controlled trials Type de document : texte imprimé Auteurs : Louis-David Beaulieu ; Marie-Hélène Milot Année de publication : 2018 Article en page(s) : p. 224-234 Note générale : Doi : 10.1016/j.rehab.2017.04.003 Langues : Anglais (eng) Mots-clés : Transcranial magnetic stimulation Stroke Upper-limb physical training Systematic review Brain plasticity Clinical outcome Résumé : Background
Physical training is known to be an effective intervention to improve sensorimotor impairments after stroke. However, the link between brain plastic changes, assessed by transcranial magnetic stimulation (TMS), and sensorimotor recovery in response to physical training is still misunderstood. We systematically reviewed reports of randomized controlled trials (RCTs) involving the use of TMS over the primary motor cortex (M1) to probe brain plasticity after upper-limb physical training interventions in people with stroke.
Methods
We searched 5 databases for articles published up to October 2016, with additional studies identified by hand-searching. RCTs had to investigate pre/post-intervention changes in at least one TMS outcome measure. Two independent raters assessed the eligibility of potential studies and reviewed the selected articles’ quality by using 2 critical appraisal scales.
Results
In total, 14 reports of RCTs (pooled participants=358; mean 26±12 per study) met the selection criteria. Overall, 11 studies detected plastic changes with TMS in the presence of clinical improvements after training, and these changes were more often detected in the affected hemisphere by using map area and motor evoked potential (MEP) latency outcome measures. Plastic changes mostly pointed to increased M1/corticospinal excitability and potential interhemispheric rebalancing of M1 excitability, despite sometimes controversial results among studies. Also, the strength of the review observations was affected by heterogeneous TMS methods and upper-limb interventions across studies as well as several sources of bias within the selected studies.
Conclusions
The current evidence encourages the use of TMS outcome measures, especially MEP latency and map area to investigate plastic changes in the brain after upper-limb physical training post-stroke. However, more studies involving rigorous and standardized TMS procedures are needed to validate these observations.Permalink : ./index.php?lvl=notice_display&id=80594

Exclu du prêtOccult periprosthetic fractures of the acetabulum in THA using an elliptic cup design have no adverse impact on outcome / Thomas Häller in Acta Orthopaedica Belgica, Vol.87/2 (Juin 2021)
[article]
Titre : Occult periprosthetic fractures of the acetabulum in THA using an elliptic cup design have no adverse impact on outcome Type de document : texte imprimé Auteurs : Thomas Häller ; Claudio Dora ; Pascal Schenk ; Patrick Oliver Zingg Année de publication : 2021 Article en page(s) : p. 299-304 Note générale : https://doi.org/10.52628/87.2.14 Langues : Anglais (eng) Mots-clés : Periprosthetic fracture acetabular fracture periprosthetic acetabular fracture total hip arthroplasty clinical outcome Résumé : Occult periprosthetic fractures have been defined as a fracture only visible on postoperative CT scans but not on postoperative plain radiography after an uneventful surgery without intraoperative fracture. The fracture rate for hemispherical and peripheral self-locking cups has been described as 8.4%. We retrospectively analyzed postoperative CT scans after primary THA to clear the question whether such occult periprosthetic fractures of the acetabulum require particular treatment strategy.
Between 2014 and 2018 we identified 115 CT scans of 114 patients after primary cementless THA with elliptical cups using a direct anterior approach. The CT scans were obtained as part of other investigations. Localization of the fracture, patients demographics, clinical (WOMAC, Harris Hip Score) and radiological outcome were analyzed.
Fracture and non-Fracture group were compared with regard to demographics and short-term outcome after 1 year.
Four occult fractures (3.5%) were identified. Three fractures involved the posterior wall. All patients had an uneventful routine postoperative rehabilitation. Patients with occult fractures showed similar post- operative HHS and WOMAC scores at 3 (HHS p = 0.576, WOMAC p = 0.128) and 12 (HHS p = 0.479, WOMAC p = 0.588) months. There were no cup loosening nor radiolucent lines at latest follow-up (mean FU 22 months, range 12-34 months).
Clinical and radiological short-term outcome was not impaired by the occurrence of an occult periprosthetic fracture of the acetabulum. The incidental detection of an occult periprosthetic fracture of the acetabulum does not seem to oblige the surgeon to adapt the postoperative regime.Permalink : ./index.php?lvl=notice_display&id=96664

Exclu du prêtThe Müller Acetabular Reinforcement Ring – Still An Option In Acetabular Revision Of Paprosky 2 Defects? Longterm Results After 10 Years / C. KÖSTERS in Acta Orthopaedica Belgica, Vol 81/2 (Juin 2015)

Titre : The Müller Acetabular Reinforcement Ring – Still An Option In Acetabular Revision Of Paprosky 2 Defects? Longterm Results After 10 Years Type de document : texte imprimé Auteurs : C. KÖSTERS, Auteur ; Benedikt SCHLIEMANN, Auteur ; D. DECKING, Auteur Année de publication : 2015 Article en page(s) : p.257-263 Langues : Anglais (eng) Mots-clés : Revision total hip arthroplasty Müller Ring acetabular reinforcement ring clinical outcome Paprosky classification Résumé : Introduction: Aim of this study was to measure the clinical and radiological longterm outcome after acetabular revision arthroplasty (RTHA) using the Müller acetabular reinforcement ring. Materials and Methods: 86 patients with 90 revision arthroplasties and a mean age of 68 years (41 to 84) were included. The mean follow-up was 10 years (range 7-12). The Harris Hip Score and the WOMAC Index were used to assess pain and functional outcome. Furthermore clinical examination of range of motion and radiologic examinations were performed in 34 patients. Results: The radiologic analysis reports no signs of loosening in 79%, 15% showed possibly loosening and 6% probable loosening. Definite radiologic loosening has not been detected. In the meantime 12 patients (13.3%) of 90 revision total hip arthroplasty underwent a revision of the acetabulum with change of the acetabular component which means a survival rate of 86.7% after 10 years follow-up. The mean center of rotation of the hip moved 0.15 cm (SD 0.74 cm) laterally and 0.1 cm (SD 0.97 cm) cranially based on the geometrically reconstructed center of rotation. A mean score of 58 points for the Harris Hip Score (range 14-93) indicated a poor functional outcome, while a mean value of 96 points (range 0-223) for the WOMAC Index indicated good results for functional outcome in daily living. Conclusions: The revision arthroplasty in cases with acetabular defects using the Müller acetabular reinforcement ring shows acceptable longterm results. Level of Evidence: Level IV.
