Key result

Functional electrical stimulation matches bicycle training for improving 6-minute walk distance in chronic HF.

n=46

Why the study?

Recent guidelines recommend regular exercise for chronic heart failure, but the safety and efficacy of home-based functional electrical stimulation compared with conventional bicycle exercise were not established.

Does functional electrical stimulation of the legs improve exercise capacity and muscle performance compared to conventional bicycle exercise training in patients with stable chronic heart failure?

Comparison

Bicycle ergometer training vs electrical stimulation of the quadriceps and gastrocnemius muscles

Implication

FES yields similar gains in exercise capacity and muscle strength as bicycle training in stable CHF; extends home-based options for mobility-limited patients.

Key Points

This study aims to compare the safety and efficacy of functional electrical stimulation versus conventional bicycle exercise for home-based training in chronic heart failure.
Forty-six patients with stable NYHA Class II/III heart failure participated in a 6-week training program.
Patients were assigned to either a bicycle ergometer group or a functional electrical stimulation (FES) group.
Assessments included 6-min walk distance, treadmill exercise time, maximum leg strength, and quadriceps fatigue index.
In the bicycle group, 6-min walk improved by 44.6m (95% CI 29.3-60.9 m) and treadmill exercise time improved by 110 s (95% CI 72.2-148.0 s).
In the FES group, 6-min walk improved by 40.6m (95% CI 28.2-53.0 m) and treadmill exercise time by 67 s (95% CI 11.8-121.8 s).
Quality of life improved overall after training, but no significant differences were observed when groups were considered separately (-0.43, 95% CI -8.13 to -0.56).

Population

46 patients (38 male) with stable NYHA Class II/III chronic heart failure

Intervention

6-week home-based training programme using functional electrical stimulation (FES) of the quadriceps and gastrocnemius muscles

Comparator

6-week home-based training programme using a conventional bicycle ergometer

Outcome

Exercise capacity and muscle performance (including 6-min walk, treadmill exercise time, maximum leg strength, and quadriceps fatigue index) at 6 weekssurrogate

Main Result

Absolute Event Rate: 40.6% vs 44.6%

Functional electrical stimulation of the legs is a safe and effective alternative to conventional bicycle exercise for home-based rehabilitation in patients with stable chronic heart failure.

Stuart Harris (2003) conducted an RCT in chronic heart failure (n=46). Functional electrical stimulation (FES) of the legs vs. Conventional bicycle exercise was evaluated on 6-min walk distance increase. Functional electrical stimulation of the legs produced similar improvements in 6-minute walk distance (40.6m vs 44.6m) compared to conventional bicycle training in patients with chronic heart failure.
