Stairclimbing Assessed by Transfer Locus of the Center of Foot Pressure

With a primary purpose of clarifying the motion characteristics of stairclimbing, transfer locus of the center of foot pressure was studied by an F-SCAN among 25 subjects (15 healthy adults and 10 patients). The loci of healthy subjects were divided into two types, started at the toe part, transferred to the heel part, and returned to the toe (type A), and started at the heel part and moved to the toe (type B, similar to walking). All the healthy subjects showed type A during descending stairs, with a significantly larger horizontal sway compared with those during ascending stairs (p
