Objective:
To examine the effects of 3 months of aerobic training (AT) followed by coaching on aerobic capacity, strength, and gait speed after subacute stroke.
Design:
Randomized controlled trial.
Setting:
Inpatient rehabilitation center.
Participants:
Patients (N=59; mean age ± SD, 65.4±10.3y; 21 women (36%); Barthel Index ≤50 in 64% of patients) with first stroke and able to cycle at 50 revolutions/min were enrolled in the study 3 to 10 weeks after stroke onset.
Interventions:
Patients were randomly allocated to a 3-month active cycling group (ACG, n=33) and education, or to a control group (CG, n=26). Afterward, patients in the ACG were randomly assigned either to a coaching (n=15) or to a noncoaching group (n=16) for 9 months.
Main Outcome Measures:
Aerobic capacity, isometric knee extension strength, and gait ability and speed were measured before and after intervention and during follow-up at 6 and 12 months.
Results:
A nonsignificant difference was found in workload (Wattpeak) (P=.078) between ACG and CG after 3 months. Furthermore, after 3 months of cycling and after 9 months of coaching, all groups showed significant changes over time (P≤.027) in peak oxygen consumption, Wattpeak, leg strength, and gait speed. Also, significant changes over time (P<.001) were found in the ACG and the CG in patients with walking inability at baseline.
Conclusions:
No significant differences between training groups were found over time. Although our study did not have objective exercise data from the training device during follow-up, the 3-month active cycling (AC) program combined with education sessions seemed an applicable method in subacute stroke rehabilitation. New long-term AT interventions should focus on coaching approaches to facilitate training after a supervised AC program.
