effect of static stretching of muscles surrounding the knee on knee Joint Position sense
British Journal of Sports Medicine, 2007Co-Authors: Farahnaz Ghaffarinejad, Shohreh Taghizadeh, Farshid MohammadiAbstract:Background: Muscle stretching is widely used in sport training and in rehabilitation. Considering the important contribution of Joint Position sense (JPS) to knee Joint stability and function, it is legitimate to question if stretching might alter the knee JPS. Objective: To evaluate if a stretch regimen consisting of three 30 s stretches alters the knee JPS. Design and setting: A blinded, randomised design with a washout time of 24 h was used. Subjects: 39 healthy students (21 women, 18 men) volunteered to participate in this study. Methods and main outcome measures: JPS was estimated by the ability to reproduce the two target Positions (20° and 45° of flexion) in the dominant knee. The absolute angular error (AAE) was defined as the absolute difference between the target angle and the subject perceived angle of knee flexion. AAE values were measured before and immediately after the static stretch. Measurements were repeated three times. The static stretch comprised a 30 s stretch followed by a 30 s pause, three times for each muscle. Results: The AAE decreased significantly after the stretching protocols for quadriceps (3.5 (1.3) vs 0.7 (2.4); p 0.05). Conclusion: The accuracy of the knee JPS in 45° of flexion is improved subsequent to a static stretch regimen of quadriceps, hamstring and adductors in healthy subjects.

effect of static stretching of quadriceps and hamstring muscles on knee Joint Position sense
British Journal of Sports Medicine, 2005Co-Authors: R Larsen, Hans Lund, Robin Christensen, H Rogind, B Danneskioldsamsoe, Henning BliddalAbstract:Objectives: To evaluate if a stretch regimen consisting of three 30 second stretches would alter Joint Position sense (JPS). Methods: A blinded, randomised, cross over design with a washout time of 24 hours was used with 20 healthy volunteers. JPS was estimated from the ability to reproduce the same Position in one knee (target versus estimated angle) expressed as the difference between target and estimated angle (constant error, CE). Measurements were repeated three times in a sitting and a prone Position on the dominant leg measured before and immediately after the static stretch. The static stretch consisted of a 30 second stretch followed by a 30 second pause, repeated three times. Results: At baseline, the mean (SD) CE was −2.71 (3.57)° in the sitting Position. No difference (p = 0.99) in CE between stretching and control was observed (0.00; 95% confidence interval −0.98 to 0.99). At baseline, the CE was −3.28 (4.81)° in the prone Position. No difference (p = 0.89) in CE between stretching and control was observed (0.12; 95% confidence interval −1.52 to 1.76). Conclusion: A static stretch regimen had no effect on JPS in healthy volunteers.

canadian cardiovascular society canadian anesthesiologists society canadian heart rhythm society Joint Position statement on the perioperative management of patients with implanted pacemakers defibrillators and neurostimulating devices
Canadian Journal of Cardiology, 2012Co-Authors: Jeff S Healey, Richard N Merchant, Christopher S Simpson, Timothy Tang, Marianne Beardsall, Stanley Tung, Jennifer Fraser, Laurene Long, Janet Van Vlymen, Pirjo ManninenAbstract:There are more than 200,000 Canadians living with permanent pacemakers or implantable defibrillators, many of whom will require surgery or invasive procedures each year. They face potential hazards when undergoing surgery; however, with appropriate planning and education of operating room personnel, adverse device-related outcomes should be rare. This Joint Position statement from the Canadian Cardiovascular Society (CCS) and the Canadian Anesthesiologists' Society (CAS) has been developed as an accessible reference for physicians and surgeons, providing an overview of the key issues for the preoperative, intraoperative, and postoperative care of these patients. The document summarizes the limited published literature in this field, but for most issues, relies heavily on the experience of the cardiologists and anesthesiologists who contributed to this work. This Position statement outlines how to obtain information about an individual's type of pacemaker or implantable defibrillator and its programming. It also stresses the importance of determining if a patient is highly pacemaker-dependent and proposes a simple approach for nonelective evaluation of dependency. Although the document provides a comprehensive list of the intraoperative issues facing these patients, there is a focus on electromagnetic interference resulting from electrocautery and practical guidance is given regarding the characteristics of surgery, electrocautery, pacemakers, and defibrillators which are most likely to lead to interference. The document stresses the importance of preoperative consultation and planning to minimize complications. It reviews the relative merits of intraoperative magnet use vs reprogramming of devices and gives examples of situations where one or the other approach is preferable.

canadian cardiovascular society canadian heart failure society Joint Position statement on the evaluation and management of patients with cardiac amyloidosis
Canadian Journal of Cardiology, 2020Co-Authors: Nowell M Fine, Margot K Davis, Kim Anderson, Diego H Delgado, Genevieve Giraldeau, Abhijat Kitchlu, Rami Massie, Jane Narayan, Elizabeth Swiggum, Christopher P VennerAbstract:Abstract Cardiac amyloidosis is an under-recognized and potentially fatal cause of heart failure and other cardiovascular manifestations. It is caused by dePosition of misfolded precursor proteins as fibrillary amyloid deposits in cardiac tissues. The two primary subtypes of systemic amyloidosis causing cardiac involvement are immunoglobulin light chain (AL), a plasma cell dyscrasia, and transthyretin (ATTR), itself subdivided into a hereditary subtype caused by a gene mutation of the ATTR protein, and an age-related wild type, which occurs in the absence of a gene mutation. Clinical recognition requires a high index of suspicion, inclusive of the extracardiac manifestations of both subtypes. Diagnostic workup includes screening for serum and/or urine monoclonal protein suggestive of immunoglobulin light chains, along with serum cardiac biomarker measurement and performance of cardiac imaging for findings consistent with amyloid infiltration. Modern cardiac imaging techniques, including the use of nuclear scintigraphy with bone-seeking radiotracer to noninvasively diagnose ATTR cardiac amyloidosis, have reduced reliance on the gold standard endomyocardial biopsy. Disease-modifying therapeutic approaches have evolved significantly, particularly for ATTR, and pharmacologic therapies that slow or halt disease progression are becoming available. This Canadian Cardiovascular Society/Canadian Heart Failure Society Joint Position statement provides evidence-based recommendations that support the early recognition and optimal diagnostic approach and management strategies for patients with cardiac amyloidosis. This includes recommendations for the symptomatic management of heart failure and other cardiovascular complications such as arrhythmia, risk stratification, follow-up surveillance, use of ATTR disease-modifying therapies, and optimal clinical care settings for patients with this complex multisystem disease.

canadian cardiovascular society canadian society of cardiac surgeons canadian society for vascular surgery Joint Position statement on open and endovascular surgery for thoracic aortic disease
Canadian Journal of Cardiology, 2016Co-Authors: Jehangir J Appoo, John Bozinovski, Michael W A Chu, Ismail Elhamamsy, Thomas L Forbes, Michael Moon, Maral Ouzounian, Mark D Peterson, Jacques Tittley, Munir BoodhwaniAbstract:In 2014, the Canadian Cardiovascular Society (CCS) published a Position statement on the management of thoracic aortic disease addressing size thresholds for surgery, imaging modalities, medical therapy, and genetics. It did not address issues related to surgical intervention. This Joint Position Statement on behalf of the CCS, Canadian Society of Cardiac Surgeons, and the Canadian Society for Vascular Surgery provides recommendations about thoracic aortic disease interventions, including: aortic valve repair, perfusion strategies for arch repair, extended arch hybrid reconstruction for acute type A dissection, endovascular management of arch and descending aortic aneurysms, and type B dissection. The Position statement is constructed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, and has been approved by the primary panel, an international secondary panel, and the CCS Guidelines Committee. Advent of endovascular technology has improved aortic surgery safety and extended the indications of minimally invasive thoracic aortic surgery. The combination of safer open surgery with endovascular treatment has improved patient outcomes in this rapidly evolving subspecialty field of cardiovascular surgery.
