long-term home-based exercise for patients with copd: the copdtoparis project

Conditions: Telerehabilitation; COPD; Quality of Life; Mobility Limitation

Summary: this randomised controlled trial (rct) aims to investigate the effect of long-term, interactive home-based cycle-exercise on patients with chronic obstructive pulmonary disease (copd) after a copd exacerbation requiring hospitalisation. the investigators aim to investigate if patients can maintain or improve the effects of pulmonary rehabilitation in terms of walking distance, intensity of copd symptoms, health related quality of life and quality adjusted life-years. participants will cycle on a pedal-exerciser in the comfort of staying in the participants' own home, whilst getting visual feedback from the 4mvideo app. the 4mvideo technology is a danish designed software system, where users can cycle forward a recording of a cyclist by treading on a pedal-exerciser, thereby getting some of the experience of a real-life cycling trip at home. the investigators will compare the clinical outcomes and daily activity levels with that of a control group consisting of copd patients.

patients with chronic obstructive pulmonary disease (copd) have a higher risk of experiencing disability, and even though participating in pulmonary rehabilitation (pr) are efficient for regaining strength, function and relieving symptoms, effects prove difficult to maintain. furthermore, physical attendance to outpatient pr is challenging for copd patients, many of whom are bound to their home, due to said disability and symptoms. even in patients who follow through with the pr programme, adherence to exercise after is a major challenge. the investigators hypothesise that an intervention group of copd-patients, who will receive home-based cycle exercise will maintain or even improve effects on physical fitness from pr, in terms of walking distance, daily activity levels (dal), exercise tolerance, disease prevention and health related quality of life (hrqol). furthermore, the investigators hypothesise that the participants express improved motivation in terms of adhering to exercise, when participating in home-based, interactive group cycle exercise. it is expected to measure changes in dal, lung function, levels of dyspnoea, exercise tolerance, walking distance, mobility, copd symptoms, activity of daily living (adl) related performance and hrqol of the participants, along with assessing disease prevention. data is compared intrapersonal and in-between groups to identify differences in outcomes at an individual level, and between intervention- and control group. furthermore, the investigators expect to uncover identifiable in-depth insights into the values and beliefs towards exercising amongst participants. 40 participants are recruited amongst copd patients that live in aalborg municipality and are admitted at aalborg university hospital, hospitalised due to acute exacerbation of copd. after being discharged participants are referred to rehabilitation, for most in their own home. after rehabilitation participants are randomized into either intervention group who will exercise on exercise bikes connected with tablets in their own home. the control group will receive usual care, which consists of offers of exercising in their own home according to a programme or participating in exercise at a facility center.
