Validity of the Pedar Mobile system for vertical force measurement during a seven-hour period

“…Moreover, insole sensors measure the ''normal'' force, which is not necessarily similar to the vertical ground reaction force (Kalpen and Seitz, 1994;Kernozek et al, 1996;McPoil et al, 1995). Only a few studies have used an insole pressure system for long-term measurements (Abu-Faraj et al, 1997;Perren and Matter, 1996;Siebert, 1994;Tveit and Ka¨rrholm, 2001). Perren and Matter concluded that their insole system (based on a hydraulic principle) was not technically reliable enough for routine use in the clinic.…”

Accuracy and repeatability of the Pedar Mobile system in long-term vertical force measurements

“…However, only a few studies described portable insole devices that can record in-shoe pressures or ground reaction forces over a long-term period [8,9]. To our knowledge, no studies have investigated the validity and reliability of these systems to measure the vertical force over a long-term period.…”

Temporal feature estimation during walking using miniature accelerometers: an analysis of gait improvement after hip arthroplasty

“…Ambulatory systems using foot switches or pressure sensors attached to the sole are used for the monitoring of temporal parameters (ROSENROT 1982;ZHU et al, 1991;ABU-FARAJ et al, 1997). These techniques present, in general, satisfactory results in normal walking.…”
