Brief Summary:
The aim of this study is to assess the effectiveness of a home-based exercise training program in COPD patients who have completed a pulmonary rehabilitation.

Condition or disease Intervention/treatment Phase
Chronic Disease Lung Diseases, Obstructive Respiratory Disease Behavioral: Exercise Not Applicable

Detailed Description:

Exercise training is an important component of the management of chronic obstructive pulmonary disease (COPD) and numerous trials have shown large improvements in health-related quality of life (HRQoL) and exercise capacity in persons with COPD. However, the great majority of patients who would benefit from pulmonary rehabilitation (PR) never follow such a program. Moreover, many COPD patients are either not instructed to exercise at all or fail to adhere to exercise training at home after completing pulmonary rehabilitation.

This study evaluates an exercise training program that requires minimal equipment (i.e., only a chair and elastic bands) and can be easily implemented long-term in the patient's home-setting.

Arm Intervention/treatment
Experimental: Exercise intervention
Home-based, minimal equipment exercise training program.
Behavioral: Exercise
Home-based exercise training program that requires only minimal equipment, and is individually adaptable to the participant's exercise level (6 times per week; 15-20 min; 38 exercise cards and one interactive training agenda booklet). After randomization, a health care professional (HOMEX coach) will visit the intervention group participants at their home to set up the training location, to instruct the exercises and to establish individualized goals. Follow-up visits are planned after 3 and 8-9 weeks. Regular telephone calls will be conducted by the same HOMEX coach to motivate the patients, to discuss training progress and concrete benefits and barriers, and to adapt goals and the training program. Additional intervention elements are that a relative or friend is involved as a "sparring" partner to support the participant. The general practitioner is informed about the participation of his/her patient in the intervention.

No Intervention: Control
Usual care (study participation does not have any impact on regular treatment or treatment decisions, including participation in other exercise training programs or rehabilitation programs)

Primary Outcome Measures :
  1. Dyspnea [ Time Frame: Change from baseline to 12 months ]
    Dyspnea domain of the Chronic Respiratory Questionnaire (CRQ); 5 questions; 7-point Likert-type scale ranging from 1 (most severe dyspnea) to 7 (no dyspnea)

Secondary Outcome Measures :
  1. Dyspnea [ Time Frame: Change from baseline to 3, 6 and 12 months ]
    Dyspnea domain of the Chronic Respiratory Questionnaire (CRQ); 5 questions; 7-point Likert-type scale ranging from 1 (most severe dyspnea) to 7 (no dyspnea)

  2. Exercise capacity [ Time Frame: Change from baseline to 12 months ]

    Six-Minute Walk Test (walk distance) and

    1-min Sit-to-Stand Test (number of repetitions)

  3. Health-related quality of life [ Time Frame: Change from baseline to 12 months ]
    Chronic Respiratory Questionnaires (CRQ): Fatigue, emotional function, mastery domain and EuroQoL (EQ-5D-5L): 5 Dimensions - Mobility, self-care, usual activities, pain/discomfort, anxiety/depression including 1 item each with 5 levels

  4. Health status [ Time Frame: Change from baseline to 12 months ]
    Visual analogue scale "Feeling thermometer" (0-100 scale; 0= "worst health you can imagine"; 100="best health you can imagine")

  5. Exacerbations [ Time Frame: During entire study, assessed at 12 months ]
    Event based, patient reported

  6. Symptoms [ Time Frame: Change from baseline to 12 months ]
    Questionnaire, COPD Assessment Test

Other Outcome Measures:
  1. Compliance to the exercise training program [ Time Frame: Assessed daily by intervention group participants during 12 months ]
    Percentage of fulfilled training sessions based on training diaries

  2. Satisfaction with the exercise training program [ Time Frame: From baseline to 12 months ]
    Questionnaire (Likert-Type scales)

  3. Experience with the exercise training program [ Time Frame: From baseline to 12 months (assessed at 12 months) ]
    Semi-structured interview

  4. Health professionals' feedback [ Time Frame: Assessed at 12 months ]
    Semi-structured interview

  5. Cost effectiveness [ Time Frame: From baseline to 12 months (assessed at 3, 6, 12 months) ]
    Questionnaire: cost per quality-adjusted life year
