“…With increased reliability, the measurement error of the instrument decreases. Applying the new technologies used for the single-leg test, including accelerometers (39), inertial (33) and ultrasonic sensors (27,(29)(30)(31)38) have been accompanied with good intra and inter observer reliability. They are valid and sensitive instruments used for precise measurements during postural balance testing.…”

“…With the knowledge of the time it takes the signal to travel and come back, and the speed, it is possible to obtain the distance between the two points (20). Since the ultrasonic sensors have been used for the measurement of lower limb rehabilitation (29)(30)(31), considering the importance of accuracy and speed in measurement of the balance abilities, the current research tries to present a newly-designed smart balance measurement device to which whether these sensors are beneficial and practical to develop and measure the static and dynamic postural balance. Then, the questions Does ultrasonic sensors precisely provide the data on static and dynamic balance positions like other technologies, including pressure and force sensors, inertial sensors, goniometers (20) etc.?…”

One of the new clinical techniques to assess the lower body parameters is the wearable ultrasonic sensors. The device which can measure the static and dynamic balance abilities in sport and clinical setting by the traveled signals of ultrasonic transmitter and receiver between two feet was developed and validated. The new device consisted of a pressure gauge and a digital centimeter indicator and examined the tests in two balanced states of Stork and Y dynamic. First, 210 participants were selected based on convenience sampling. Then, using the new ultrasonic balance device, all samples took each test conducted by the Stork and Y dynamic tests for3 times. The results showed high reliability between the data of static and dynamic balances obtained from the ultrasonic device and through the methods of Stork and Y (the SEBT modified version) (r=0.90; r=0.92). The inter-rater reliabilities of the three-time conduction of the stork and Y dynamic tests were found to be very high (ICC=0.92; ICC=0.91). The ultrasonic balance device was both valid and reliable in measuring the Stork and Y dynamic balance tests. The new device could solve that defects associated with traditional stork and Y dynamic tests.

Measuring the foot plantar pressure has the potential to be an important tool in many areas such as enhancing sports performance, diagnosing diseases, and rehabilitation. In general, the plantar pressure sensor should have robustness, durability, and high repeatability, as it should measure the pressure due to body weight. Here, we present a novel insole foot plantar pressure sensor using a highly sensitive crack-based strain sensor. The sensor is made of elastomer, stainless steel, a crack-based sensor, and a 3D-printed frame. Insoles are made of elastomer with Shore A 40, which is used as part of the sensor, to distribute the load to the sensor. The 3D-printed frame and stainless steel prevent breakage of the crack-based sensor and enable elastic behavior. The sensor response is highly repeatable and shows excellent durability even after 20,000 cycles. We show that the insole pressure sensor can be used as a real-time monitoring system using the pressure visualization program.

“…Wearable in-shoe pressure soles overcome this problem but are technically more complicated because each foot is measured independently and only pressure on distinct areas of the sole is considered [3]. Several studies presented or compared in-shoe pressure soles regarding their technical abilities, limitations and application in common research problems [3], [4], [5]. These systems were validated with technical parameters.…”

Static posturography is an important measurement in the diagnostic workup for patients with postural instability. New wearable sensor technologies enable researchers to use in-shoe pressure soles in the home environment and outdoor applications. In this study a newly developed in-shoe pressure sole was used for calculating the sway path and 95% confidence ellipse area as the standard parameters of typical static posturography. Insole posturography was validated on 24 subjects by a state of the art pressure plate assessment during three static posturography conditions (eyes open, eyes closed and barefoot). The adaptive low pass filtered data resulted in an overall correlation of 0.63 to 0.78 for the sway path and 0.66 to 0.79 for the 95% confidence ellipse area. Individual correlations of up to 0.97 for the sway path and 0.99 for the 95% confidence ellipse area could be obtained. Future applications could utilize the mobile advantage of in-shoe pressure soles and measure static and dynamic posturography in clinical and home environments.
