Timeline of the experimental protocol. The term “fixed” denotes fixed order (grey lines) while the term “random” indicates random order (black lines) of the assessments and conditions. After performing the thresholds assessment, the participant was randomly allocated to the JND and NDI or 2PD assessment. For all the assessments, the sitting (“S”) and walking (“W”) conditions were ordered randomly, with the exception of the last block, where the order was fixed (SD assessment). Annotations: "ST, DT": sensation and discomfort threshold; "JND": just noticeable difference; "NDI": number of distinct intervals; "2PD": two-point discrimination threshold; "SD": spatial discrimination; "S": sitting; "W": walking
