Objective:
To investigate the effects of a supervised longer- (14wk) versus shorter-duration (7wk) rehabilitation program after lung transplantation (LTX).
Design:
Randomized controlled trial.
Setting:
Outpatient rehabilitation gym setting.
Participants:
Post-LTX patients aged ≥18 years (N=66; 33 women; mean age, 51±13y) who had undergone either single LTX or bilateral LTX.
Intervention:
Outpatient rehabilitation program consisting of thrice-weekly sessions with cardiovascular training on bike ergometer and treadmill plus upper and lower limb strength training.
Main Outcome Measures:
Measures were taken at baseline, 7 weeks, 14 weeks, and 6 months by assessors who were blinded to group allocation. Functional exercise capacity was measured by the 6-minute walk test (6MWT). Strength of quadriceps and hamstrings was measured on an isokinetic dynamometer and recorded as average peak torque of 6 repetitions for both muscles. Quality of life (QOL) was assessed with the Medical Outcomes Study 36-Item Short-Form Health Survey.
Results:
Of the participants, 86% had bilateral LTX and 41% had primary diagnosis of chronic obstructive pulmonary disease. The 6MWT increased in both groups with no significant difference between groups at any time point (mean 6mo 6MWD: short, 590±85m vs long, 568±127m; P=0.5). Similarly, at 6 months, there was no difference between groups in quadriceps average peak torque (mean, 115±38Nm vs 114±40Nm, respectively; P=.59), hamstring average peak torque (57±18Nm vs 52±19Nm, respectively; P=.36), or mental or physical health domains of quality of life.
Conclusions:
Shorter duration (7wk) of rehabilitation achieves comparable outcomes with 14 weeks of supervised rehabilitation for functional exercise capacity, lower limb strength, and quality of life at 6 months after LTX.
