Enhancing Muscle Function After Exacerbations of COPD to Limit Its Impact on Physical Activity Decline

COPD Exacerbation Clinical Trial

Official title: Enhancing Muscle Function After Exacerbations of COPD to Limit Its Impact on Physical Activity Decline

Status Recruiting

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.

Clinical Trial 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. ;
