“…It is also noticed that this classification might not be sustainable for older adults and those living with chronic diseases. There are a few studies that measured daily physical activity in patients with COPD with an accelerometer [51][52][53] and with a pedometer [31]. Patients in the latter study took approximately 3700 steps/day.…”

“…By incorporating these activities during pulmonary rehabilitation, daily physical activity levels may remain higher after rehabilitation and the benefits of rehabilitation may last longer. The Dutch Norms for Healthy Physical Activity (DNHPA), which is derived from the www.elsevier.com/locate/pateducou Patient Education and Counseling 61 (2006) [48][49][50][51][52][53][54][55] norms of the American College of Sports Medicine (ACSM) [9][10][11], serve as reference for the effects of lifestyle physical activities on health.…”

Disability and Rehabilitation, 32(22):1819-1826. Postprint available at: http://www.zora.uzh.ch Similarly, ambulatory activity monitoring did not correlate significantly with self-reported functional status in patients with chronic obstructive pulmonary disease. [20] To the best of our knowledge, only one previous report has investigated the relationship between ambulatory step activity monitoring, self-reported physical functioning and the 6-minute standardized walking test in cancer patients.[28] There was moderate agreement between the 7-Day Physical Activity Recall and the accelerometer with longitudinal serial correlation coefficients of 0.54 (baseline), 0.24 (year 1), and 0.53 (year 2), all p-values <0.01.To summarize, the association observed between self-reported physical functioning, standardized timed walking and the outputs of ambulatory step activity varies from none to almost perfect in studies of various chronic disease populations. Only one study has investigated this issue in cancer patients, and none among HSCT patients. The aim of the current study was to determine the degree of association between self-reported physical functioning, standardized timed walking and the outputs of ambulatory step activity monitoring among outpatients with haematological malignancies recovering from HSCT. Methods ParticipantsThis study presents a cross-sectional analysis of baseline data collected from a subset of 117 ambulatory hematological patients after completion of HSCT at the University HospitalZurich and the Cantonal Hospital of St. Gallen, Switzerland. These baseline data were 4 collected before the patients were randomized between an ambulatory physical exercise intervention and a usual care (i.e., non-exercising) control group. Adult patients were considered eligible for the study if they had completed their HSCT treatment. Patients were excluded from the study in case of graft versus host disease (GVHD) except for grade I not requiring treatment, painful joints, instable osteolyses, chronic pain, lesions of the central or peripheral nervous system, uncontrolled cardiovascular disease, thyroid disease or diabetes.The study was approved by the local ethical committee. All patients provided written informed consent. MeasurementsAmbulatory step activity levels were assessed with the Step Activity Monitor 3 (SAM3, Cymatech Corporation, Seattle, WA, USA). The patients were instructed to wear the SAM3 for 7 consecutive days. Activity monitoring over a 7-day period has previously been found to result in reliable and representative measures of an individual's movements on a day-to-day basis.[17] All participants were instructed to leave the SAM3 on the ankle if they had to rest or lay down during the day and to perform their daily activities as usual. The parameters assessed by the SAM3 for this study were: (1) `average steps/day`, (2) ...

“…In the study by Baghai-Ravary et al 64 fatigue remained the only factor significantly associated with time spent outdoors, suggesting fatigue is considerable restrictor of physical activity. One study found fatigue to be one of the correlates to physical activity measured with an activity monitor 53 while another study did not found a relation between fatigue and physical activity measured with an accelerometer 49 . To elucidate the pathway to low PA in COPD we need to understand which factors are important contributors to PA.…”

Background Chronic Obstructive Pulmonary Disease (COPD) is increasing throughout the world and most rapidly among women. COPD is characterized by a progressive loss of physical functions. The reason for this is multi-factorial and include not only lung related deficiencies but also several systemic consequences and symptoms of which several are potential restrictors of physical function. The relationship between physical function and symptoms are not clear, especially not among women with COPD. Aim The overall aim of this thesis was to illuminate the relationship between two dimensions of physical function (physical activity and physical capacity) and experience of fatigue. The specific aims were to explore factors associated with low physical activity and to examine experience of fatigue and its relationship to physical capacity and disease severity in men and women with COPD. Methods A cross-sectional study was conducted including 121 patients (67 women) with stable COPD and mean age of 67 (+/-7) years. Physical activity was measured with the International Physical Activity Questionnaire short form. Physical capacity included assessment of lung function (dynamic spirometry), exercise capacity (the 6-minute walk distance [perceived dyspnoea and leg fatigue in connection to the test]) and muscle strength (the Timed Stands Test and grip strength). Fatigue was assessed with structured questions covering the frequency, duration and severity of fatigue the previous month and patients were categorized as those with no fatigue, moderate fatigue or severe fatigue. Data about other symptoms (dyspnoea, anxiety and depression), symptom burden (Memorial Symptom Assessment Scale), fat and fat free mass (bio-impedance analysis) and smoking history was collected. Results Forty-two percent of the patients reported a low physical activity level. A majority of the patients reported experience of fatigue the previous month, 52% moderate fatigue and 25% severe fatigue. Low physical activity was associated with severe fatigue, worse exercise capacity and a higher amount of smoking. There were no differences in experience of fatigue between men and women. Men with fatigue had worse physical capacity and disease severity compared to men without fatigue. Women with fatigue had comparable physical capacity and disease severity to women without fatigue except for a higher perceived leg fatigue after the exercise capacity test. Multiple logistic regression analysis showed that exercise capacity and disease severity were associated with fatigue in both men and women but in women, leg fatigue was also strongly associated with the presence of fatigue. Conclusions Severe fatigue, worse exercise capacity and a higher amount of smoking were independently associated with low PA. This result suggests that patients with severe fatigue might need specific strategies to become more physically active. Presence of fatigue was associated with exercise capacity and disease severity in both men and women. In addition, in women leg fatigue was strongly a...

Correlates of Physical Activity in Chronic Obstructive Pulmonary Disease

Abstract: Accelerometer measurement of functional performance was most significantly related to walking abilities. This methodology represents a novel approach to measuring an important dimension of functional status not previously well quantified.
