Clinical Trial Summary

Patients with COPD lose muscle strength during acute exacerbations of COPD (AECOPD) which interferes improving the recovery of physical activity (PA) after an AECOPD. Resistance training can reverse this process. An exercise training program with the focus on resistance training is essential in minimizing the long-term effects of AECOPD as it may help to accelerate the gain in PA in the weeks after an acute event. Therefore, it is important that such programs are embedded at the right moment (i.e. immediately after an AECOPD) and in a setting accessible to the patient (i.e. primary care). The efficacy and effectiveness of implementing such training programs will be assessed in the present study.

Description:

The present study aims to: 1. Investigate whether an 8 week exercise training program provided in primary or community care enhances lower limb muscle strength in patients following an AECOPD; 2. Investigate whether such programs assist patients after an AECOPD to re-engage with a coaching intervention geared to long-term PA maintenance or improvement. The secondary aim is to investigate how (repeated) AECOPD contribute to structural alterations in the skeletal muscle and how an exercise training program and PA can influence the deterioration in muscle fiber morphology and signals related to muscle atrophy. Patients that experience a moderate or severe AECOPD will be recruited in the present multicentre randomised controlled trial (RCT). Patients in this study will have at least 3 clinical visits: - Post AECOPD treatment: screening and randomisation visit (V1) - 8 weeks after randomisation (V2a and V2b*) - 52 weeks after randomisation (V3a and V3b*) - If patients agree to have a muscle biopsy taken, a V2b and V3b will be added, so this does not interfere with other measurements. These visits will take place 1-2 weeks after V2a and V3a, respectively. After the screening and randomisation visit (V1), the patient will be randomised in either the intervention group (PA coaching and exercise training) or the control group (PA coaching). Patients in the intervention group will receive a first physiotherapy session during this first visit provided by the trained researchers (with a degree in physiotherapy) to get acquainted with the exercises. Information about the PA coaching will be given to all the patients. The intervention will be started after this visit and is provided by a physiotherapist in primary or community care.

Intervention

Behavioral:
• PA coaching
PA coaching: Patients receive a step counter together with a coaching application (m-PAC, AppsOnly, KU Leuven) installed on a smartphone. The step counter and coaching application are connected via Bluetooth. The coaching application has the goal of PA promotion as well as detecting any new AECOPD.

Other:
• Exercise training
Each session will include at least the following components: Resistance training of the lower limbs: Exercises for 6 muscle groups using minimal (e.g. ankle weights or elastic resistance bands) or no (body weight) equipment are foreseen. Each exercise will be performed in 3 series of 8 repetitions. Functional training: Sit to stand exercise and stair climbing. During the first 2 weeks of the exercise training program, at least 3 strength exercises and 1 functional exercise will be performed each session. Starting from the 3rd week of the exercise training program, whole body exercise training (interval training for walking, cycling, stair climbing and high knees) will be added. From this moment on, at least 1-2 whole body exercises and 2-3 strength and functional exercises will be performed during each physiotherapy session. By doing this, each session will consist of a minimum of 4 exercises in total.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Daily number of steps at 52 weeks	Change in daily mean step count 52 weeks post randomization in the intervention group as compared to the control group. Physical activity will be objectively measured for 1 week using a tri-axial accelerometer validated for use in patients with COPD. At least 4 valid weekdays (> 8 hours of wearing time during waking hours) is necessary to label the physical activity measurement as valid.	52 weeks
Primary	Isometric quadriceps force	Isometric quadriceps strength of the right leg will be measured using the strain gauge device (Sauter Controls NV, Zellik, Belgium) with the hip and knee in 90° flexion. Four repetitions will be performed using standardized encouragement with the first attempt not being maximal and not counting as a possible best result. The best of the last three measurements will be used.	8 weeks
Secondary	Functional exercise capacity	Change in six-minutes walk distance between baseline and 52 weeks post randomization in the intervention group as compared to the control group. The six-minutes walk test will be performed with standardized encouragement to assess patients' functional exercise capacity. The best of two measurements will be used.	8 and 52 weeks
Secondary	Isometric quadriceps force	Isometric quadriceps strength of the right leg will be measured using the strain gauge device (Sauter Controls NV, Zellik, Belgium) with the hip and knee in 90° flexion. Four repetitions will be performed using standardized encouragement with the first attempt not being maximal and not counting as a possible best result. The best of the last three measurements will be used.	52 weeks
Secondary	Functional performance	This will be evaluated using the SPPB. This test assesses lower extremity function and mobility. It consists of 3 subtests that are scored and points are added up: 4-meter gait speed: To evaluate the patient's functional gait speed. The test is repeated twice. The best time of the 2 attempts is used for the rating. Cut-off: <0.3 m/s or =0.3 m/s.; 5 times sit to stand: This test quantifies the functional lower extremity strength. In this test, patients are asked to complete 5 cycles sit-to-stand as fast as possible from a 45 cm height chair. The participant may practice 1 repetition prior commencing the test. The time needed to perform 5 repetitions is noted. Cut-offs: =11.19 seconds (4 points); A higher score indicates a better functional performance.	8 weeks and 52 weeks
Secondary	Health related quality of life	Change in health related quality of life wil be measured by the Chronic Respiratory Disease Questionnaire (CRDQ-SAS) (dyspnea domain): This disease specific questionnaire measures both physical and emotional aspects of the chronic respiratory disease. The questionnaire contains 20 items, spread over 4 domains (dyspnea, fatigue, emotional function and mastery). The MCID is reflected by a change in score of 0.5 on a 7-point scale for each of the CRDQ domains (28). Only the dyspnea domain will be used for this study. The self-administered standardized (CRDQ-SAS) version will be used. A higher score indicates a higher health related quality of life.	8 weeks and 52 weeks
Secondary	Health status	Change in health status will be measured using the COPD Assessment Test (CAT): This validated 8-item questionnaire assesses the impact of the disease on a patient's health status. Scores range from 0 (good health status) to 40 (worse health status). The minimal clinical important difference (MCID) is a change of 2 points (19).	8 weeks and 52 weeks
Secondary	Patient experience of PA	Change in patient experience of physical activity will be measured using the Patient Reported Outcome (PRO) -active (C-PPAC) questionnaire: a simple, valid and reliable 12-item questionnaire assessing PA from a patient's perspective reflecting on the past 7 days. The questionnaire investigates the experienced amount of and difficulty of PA as perceived by the patient. The 2 domain scores as well as the total score will be retrieved as outcomes. The clinical visit version will be used. A paper version of the questionnaire will be given along with the monitor. Subscores and total score are from 0 to 100, with higher score meaning less problems with daily life activities as reported by the patient	8 weeks and 52 weeks
