Memory for symptoms in COPD patients: how accurate are their reports?

Accurate assessment of the amount and intensity of physical activity in daily life is considered very important due to the close relationship between physical activity level, health, disability and mortality. For this reason, assessment of physical activity in daily life has gained interest in recent years, especially in sedentary populations, such as patients with chronic obstructive pulmonary disease (COPD).The present article aims to compare and discuss the two kinds of instruments more commonly used to quantify the amount of physical activity performed by COPD patients in daily life: subjective methods (questionnaires, diaries) and motion sensors (electronic or mechanical methods). Their characteristics are summarised and evidence of their validity, reliability and sensitivity is discussed, when available.Subjective methods have practical value mainly in providing the patients' view on their performance in activities of daily living and functional status. However, care must be taken when using subjective methods to accurately quantify the amount of daily physical activity performed. More accurate information is likely to be available with motion sensors rather than questionnaires. The selection of which motion sensor to use for quantification of physical activity in daily life should depend mainly on the purpose of its use.

Definition of pulmonary rehabilitation The American Thoracic Society and the European Respiratory Society have recently adopted the following definition: pulmonary rehabilitation (PR) is an evidence-based, multidisciplinary, and comprehensive intervention for patients with chronic respiratory diseases who are symptomatic and often have decreased daily life activities. Integrated into the individualized treatment of the patient, PR is designed to reduce symptoms, optimize functional status, increase participation, and reduce healthcare costs through stabilizing or reversing systemic manifestations of the disease. Comprehensive PR programs include patient assessment, exercise training, education, and psychosocial support [Nici et al. 2006]. We will first address the pathophysiology and main consequences of chronic obstructive pulmonary disease (COPD), since it is a disease not only characterized by pulmonary inflammation and structural abnormalities leading to airflow obstructions, exercise limitation and symptoms of dispnea and fatigue, but also extended to a variety of systemic alterations. These extrapulmonary effects include systemic inflammation, nutritional abnormalities and weight loss, skeletal muscle dysfunction, and additional organ effects. The high burden of COPD is further contributed to by systemic effects, leading to a pronounced deterioration in health status and a diminished quality of life (QoL). Chronic obstructive pulmonary disease: pathophysiology and consequences Peripheral and respiratory muscles dysfunction The principal symptom limiting exercise in patients with COPD is dyspnea, due to changes in the respiratory mechanics and impaired pulmonary gas exchange (Table 1). Hamilton and colleagues [Hamilton et al. 1996] noted that lower limb fatigue in isolation was greater than the sensation of dyspnea in 43% of patients with COPD who had maximal exercise testing. Although lower limb muscles are largely responsible for limiting activities such as walking and going up inclines or

“…The pulmonary functional status www.intechopen.com and dyspnea questionnaire-modified version (PFSDQ-M), measure dyspnea, fatigue, and activity levels (Lareau et al,1994). PFSDQ-M has been used to measure fatigue in COPD patients (Meek et al 2001). The PFSDQ-M comprises three domains: influence of dyspnea on ADLs, influence of fatigue on ADLs and change experienced by the patient in ADLs.…”

“…The Multidimentional Assessment Of Fatigue (MAF); MAF (16 items) was originally designed for arthritis patients (Belza, 1993;Tack, 1990), It has been used in cancer patients (Meek et al, 2001) and with chronic pulmonary disease (Belza et al, 2001). The MAF surveys four dimensions: severity, measured by items 1 and 2; distress, item 3; degree of interference in activities of daily living, items 4 through 14; and, finally, timing (frequency of occurrence and changeability), items 15 and 16 (Belza, 1993;Tack, 1990).…”

“…Living with COPD can be challenging, as the disease dramatically impacts patients' daily life. When disease symptoms especially dsypnea affects the performance of daily activities, the potential exist for important changes to occure in individual's overall quality of life (Meek et al, 2001). COPD is associated with increased risk for anxiety, depression, and other mental health disorders (Dowson et al, 2004;Singer et al, 2001).…”
