Pressure measurement studies

In-shoe pressure measurement in research: studies with GP MobilData and GT Radix

The in-shoe pressure measurement system by GEBIOM from Münster, Germany, has been used in scientific studies for years – under the names GP MobilData, GP MobilData WiFi, GP MobilData Funk and GP MobilData Bluetooth. The current generation is called GT Radix and is distributed by go-tec. Below you will find a selection of publications with a link to the source.

Validity and reliability

How accurate are pressure insoles? A comparison with the force plate

Concurrent Validity and Test–Retest Reliability of Pressure-Detecting Insoles for Static and Dynamic Movements in Healthy Young Adults

Lambrich, Hagen, Schwiertz, Muehlbauer2023Sensors 23(10), 4913GP MobilData WiFi

What it is about

22 healthy adults standing, walking, running and jumping, measured simultaneously with insoles and a force plate, plus a repeat measurement. The study found high agreement and mostly good to excellent reliability; absolute force values were lower than those of the force plate.

Clinical practice and rehabilitation

Pressure relief from post-operative shoes

Pressure-Relief Effect of Post-Op Shoes Depends on Correct Usage While Walking

Döhner et al.2025Bioengineering 12(5), 489GP MobilData (in-shoe sensors)

What it is about

Plantar pressure distribution and the relief effect of a post-operative shoe with different walking patterns, studied in 16 healthy adults.

Measuring partial weight-bearing after surgery objectively

Efficacy of a Low-Cost Weight-Bearing Sensitivity Incentivator After Lower Limb Surgery: A Pilot Randomised Controlled Trial

Manelli et al.2025Applied Sciences 15(10), 5784GP MobilData, wireless

What it is about

Randomised pilot study with 34 patients after lower limb surgery. GP MobilData was the instrument for measuring actual loading; the device under study was a separate feedback insole.

Tennis: open and square stance

The role of increased post-impact ball speed on plantar pressure during open and square stance groundstrokes in female tennis players

Lambrich, Muehlbauer2024BMC Sports Science, Medicine and Rehabilitation 16, 129GP MobilData WiFi

What it is about

Plantar loading in different stances and at different ball speeds, measured with pressure insoles in tennis shoes.

Sensorimotor insoles with a peroneal pressure point

The influence of insoles with a peroneal pressure point on the electromyographic activity of tibialis anterior and peroneus longus during gait

Ludwig, Kelm, Fröhlich2016Journal of Foot and Ankle Research 9, 33GP MobilData

What it is about

In a pilot test with twelve people, GP MobilData measured the local pressure between the sensorimotor insole element and the skin; the main study examined muscle activity by EMG.
