Brief Summary

The chronic airflow limitation in chronic obstructive pulmonary disease (COPD) patients resulting in increased dyspnea during physical activity restricts many COPD patients ability to perform exercises in general and whole-body exercises in particular. Single limb training performed as one-legged cycling has been shown effective in patients with COPD. This exercise regime results in less stress on the ventilatory system as training is executed using a simultaneously smaller muscle mass. However, the positive physiological effects of exercise training only occur in the involved muscle(s). To be of benefit for patients daily life, all relevant muscles should be included in exercise training. The aim of the current randomized controlled multicenter trial (RCT) is to determine the effects of high-repetitive single limb exercises (HRSLE) in combination with COPD specific patient education, compared to the COPD specific patient education alone in patients with moderate to very severe (stage II-IV) COPD.

Outcome Measures

Primary Outcomes (3)

  • Quality of life

    The Swedish Self-Administered Standardized version of the Chronic Respiratory Disease Questionnaire (CRQ-SAS) will be used as primary outcome measure to asses quality of life

    Before single limb exercise regime and on completion (at 8 weeks)

  • Functional lower extremity muscular endurance

    To asses muscular endurance in the lower extremity the 6-minute walk test will be used as primary outcome measure.

    Before single limb exercise regime and on completion (at 8 weeks)

  • Upper extremity muscular endurance

    The 6-minute ring and pegboard test will be used as primary outcome measure for upper extremity muscular endurance

    Before single limb exercise regime and on completion (at 8 weeks)

Secondary Outcomes (12)

  • Isokinetic maximal muscle strength

    Before single limb exercise regime and on completion (at 8 weeks)

  • Upper extremity muscular endurance

    Before single limb exercise regime and on completion (at 8 weeks)

  • Isokinetic muscular endurance capacity

    Before single limb exercise regime and on completion (at 8 weeks)

  • Self-efficacy

    Before single limb exercise regime and on completion (at 8 weeks)

  • Anxiety and Depression

    Before single limb exercise regime and on completion (at 8 weeks)

  • +7 more secondary outcomes

Study Arms (2)

Control group

ACTIVE COMPARATOR

The control group will receive standardized patient education four times, once every two weeks, during the eight week intervention period.

Behavioral: Control group

High-repetitive single limb training

EXPERIMENTAL

The experimental group will receive a high-repetitive single limb exercise regime, three times a week for two months. In addition, the exercise group will receive patient education at four occasions during the intervention period.

Behavioral: High-repetitive single limb training

Interventions

Control groupBEHAVIORAL

The control group receives standardized patient education four times, once every two weeks, during the eight week intervention period. Each session will last 60 minutes, consisting of information regarding anatomy, physiology, causes and mechanisms of COPD, drugs, nutrition, aids and energy saving procedures. The information is the same as for the intervention group, given at separate occasions.

Control group

The high-repetitive single limb exercise regime consists of three sessions per week during eight weeks of exercise training, giving a total number of 24 sessions at each location (Umeå and Huddinge University hospitals). The exercise sessions are supervised and conducted by a physical therapist using a group format, six to eight participants in each group. Each session will span for 60 minutes, duration of the major components are: 10 min warm-up followed by 40 minutes of single limb training and 10min cool-down. In addition this experimental group also receives four sessions of patient education once every two week.
