Definition of a randomized controlled trial

Well-designed randomized clinical trials (RCTs) on the efficacy and effectiveness of ankle-foot orthoses (AFOs) in stroke patients are scarce. Our Dutch colleagues, De Wit et al., published a paper 'The effect of an ankle-foot orthosis on walking ability in chronic stroke patients: a randomized controlled trial' in Clinical Rehabilitation 2004; 18: 550_557.' We ask, is this study really an RCT?'
