Patients with peripheral artery disease 'underestimate walking progress'
Self-reported improvement after exercise programs tends to fall short of objective data, researchers say
Taking the word of patients with peripheral artery disease (PAD) on whether they can walk farther after an exercise program is likely to significantly underplay the benefit of the intervention, a US study suggests.
This effect could be important, particularly in trials comparing revascularisation with exercise that use patient-reported outcomes, the authors caution.
Researchers from Chicago pooled results from three trials in 400 patients with PAD who were
