main-button pedoped

The new pedoped®  insole monitors the normal plantar force between the foot and the shoe.

It is now possible for the first time to accurately measure the force statically or dynamically inside a shoe during walking and running utilizing only one large sensor which covers the entire plantar surface of the foot.
The force between the foot and the shoe is accurately measured independent from which part of the foot is making contact with the ground. This was not previously possible due to the typical characterization of partly loaded pressure sensors. To accomplish a total plantar force calculation current technology utilizes sophisticated electronics and a dense matrix of pressure sensors in which the total force was summed across all sensors.

In contrast, the pedoped® covers the entire plantar surface of the foot with one large linear sensor that avoids errors due to partly loading. For applications in which the distribution of localized loads are not of interest, but rather the total load on the foot is of importance, the new pedoped® insole is the optimal solution. This new technology has a matchbox sized electronics and communicates wirelessly with a smartphone via Bluetooth®. The data is transmitted to the smartphone real-time so that the subject can receive an instantaneous biofeedback via sound or vibration. The data can be stored inside the smartphone .

The data can later be transferred  to a PC for multiple analysis of the data matching with the specific task. Long term monitoring of body load as well as instability, fatigue, performance and biofeedback are possible. Later on the pedoped® sensor may also be divided into 3 areas such as forefoot, midfoot or hindfoot for a more detailed analysis of force production. The pedoped® insoles come in any foot size and can be custom made for specific applications.

To eliminate any disturbance or influence to the proprioception of the foot, the small electronics are connected to the insole via a very thin flexible band and then attached to the lacing or shoe upper. This method was chosen over embedding the electronics directly into the insole. Additionally, it is possible to place the pedoped® insole in the shoe at the same time as a subject’s corrective insole without disturbing the biomechanics and proprioception. For certain applications where either corrective insoles are not used or the proprioception is not a concern the hardware can also be imbedded into the shoe or insole on demand. Several smartphone apps will be available for the pedoport® software, each tailored to the specific application such as long-term load monitoring with biofeedback, bipedal comparison of normal ground reaction force, balance and stability of gait, or monitoring of forefoot walking/running.

The measurement rate of the pedoped® insole can be user-defined up to 250Hz for bi-pedal measurement. The raw data are available so that users may program their own applications.

load monitoring device

The new pedoped® load monitoring device accurately measures the normal plantar force detected inside the shoe during all static and dynamic activities. This is the first system to utilize a single sensor integrated with compact matchbox size wireless electronics for data processing and transmission. In addition, this is the first system of this size and capability which can accurately measure the true normal plantar force inside the shoe without estimation from other variables such as body weight, acceleration, etc.
