Effects of additional load at different heights on gait initiation: A statistical parametric mapping of center of pressure and center of mass behavior
Fig 3
Average medial-lateral (ML) and anterior-posterior (AP) center of mass (COM) anticipatory postural adjustments (APA) phase components, with additional weight positioned at the waist (A and B, respectively) and shoulder (C and D, respectively) and their corresponding differences compared to the no-load (NL) condition.
WUD: weight uniformly distributed at the waist; WST: weight positioned at the waist on the stance foot side; WSW: weight positioned at the waist on the swing foot side, SUD: weight uniformly distributed at the shoulder; SST: weight positioned at the shoulder on the stance foot side; SSW: weight positioned at the shoulder on the swing foot side.
