Abstract: Introduction: The maintenance of balance and body orientation during standing is essential to perform different activities. One of the devices used to measure balance them is the force platform. This device measures the ground reaction force (GRF) and displacement of the center of pressure (COP), both biomechanical parameters involved in human motion. This article proposes a new design for non-commercial low-cost force platforms for scientific research purposes. Methods for calibration and validation are also … Show more

“…Thanks to its concise design, Equimetrix sensing mat weighs only 2.6 kg and can be folded in two parts for easy transportation ( Figure 3 ). Both these features, along with the large sensing area available, present an increased advantage when compared to traditional stability measurement devices, or even to other custom made solutions designed for portability and low cost [ 42 ].…”

“…Parameters derived from the COP trajectories obtained by a high-precision force plate are considered to be the gold standard of balance performance [ 29 , 30 ]. There are two types of commonly used force plates: (1) uniaxial force plates equipped with a single-axis load cell that measure only the vertical component (F Z ) of the ground reaction force and (2) force plates equipped with load cells (strain gauges or piezoelectric sensors usually arranged on the four corners of the plate), which can obtain the three components, F X , F Y , and F Z, of the ground reaction force and the moment of force acting on the plate.…”

“…The force plates design optimisation was a compromise among maximum rigidity, minimum mass and high frequency, which allows small deformations, uncoupling, good linearity and low hysteresis (c.f. [17]). The specific force plate application determined proper resonance frequencies and the maximal vertical load was supported.…”

“…Commercial force plate prices are~$20,000, which can usually be very expensive for coaches and biomechanists [16]. Beside the high prices, technical assistance issues and spare parts' availability are sources of many difficulties for labs and researchers [17]. Thus, due to the high cost of existing force plate systems, the development of simpler low cost, adjustable and accurate models for biomechanical analysis is desirable for force measurements in swimming start and turn techniques (cf.…”
