Details and patient eligibility


The Functional Difficulties Questionnaire-shortened version "(FDQ-s) is a unique questionnaire that aimed at evaluating the functional performance of the upper extremities and trunk following cardiothoracic surgery. Aim of this study is adaptation of the FDQ-s questionnaire to Turkish culture and study its psychometric properties, validity and reliability.

Full description

Cardiac surgeries performed by sternotomy method are the most common surgical treatment method in coronary artery disease. Although the median sternotomy has advantages in terms of ease of application, cost and long-term survival, muskuloskeletal complications can be encountered in the postoperative period. In the studies conducted, it was found that patients had difficulties in functional activities including mobilization and daily life activities after median sternotomy. Also restrictions or loss of motion can be observed in the joint range of motion of the shoulder joint and thoracic region. The FDQ-s scale consists of 10 functional tasks developed by Sturgess et al. These tasks are activities such as coughing, sneezing, deep breathing, movements involving the upper extremity, turning in bed, sitting upright in the chair, and ambulation. When applying FDQ-s, patients will mark how hard they are in each task on the 100 mm straight line. The first point on the left means "no difficulty" and the last point on the right means "maximum difficulty". The score will be determined by measuring from the starting point to the place marked by the patient. The total score is at most 100 points and at least 0 points. The high score indicates that the patient's difficulty level is high. Although there are many functional difficulties faced by patients in the postoperative period, there is no outcome measurement in our language that evaluates the level of these difficulties globally and objectively. Our research will be done due to the elimination of this deficiency in the literature.
