Table 2.

List of articles resulting from a search of literature databases (PubMed, EBSCO, CINAHL, Cochrane library, and UMI Dissertation). Only the articles containing basic ST gait parameters are listed. Articles shown in bold print contained information pertaining to the effect of treatment on basic ST gait parameters in patients with PAD, which met the criteria for detailed review.
