“…There are two types of ultrasonic transceivers, one relies on reflection from the surface, as the one used in [24,25]. The distance measurement of such ultrasonic sensor is the returned distance reflected from the ground, and the orientation of foot during walking is not considered.…”

In this paper, a low-cost motion analysis system using a wireless ultrasonic sensor network is proposed and investigated. A methodology has been developed to extract spatial-temporal gait parameters including stride length, stride duration, stride velocity, stride cadence, and stride symmetry from 3D foot displacements estimated by the combination of spherical positioning technique and unscented Kalman filter. The performance of this system is validated against a camera-based system in the laboratory with 10 healthy volunteers. Numerical results show the feasibility of the proposed system with average error of 2.7% for all the estimated gait parameters. The influence of walking speed on the measurement accuracy of proposed system is also evaluated. Statistical analysis demonstrates its capability of being used as a gait assessment tool for some medical applications.

In recent years, human motion tracking based on inertial sensors took a huge leap forward as a cost effective enabling technology. It overcomes the limitations of existing tracking systems such as magnetic, mechanical and optical in terms of power, cost and size. It has high impact in the areas of human performance assessment and human-robot interaction as illustrated in gait analysis and assistive devices control. It can be used as a method for alternate gait analysis overcoming the limitations of motion capture systems which are restricted to indoor environment. Also, human motion intention estimation is made possible with the help of these devices and is useful in exoskeleton control. This paper surveys the role of inertial based systems in human gait analysis and lower limb exoskeleton control. In the later part of the paper, state-of-the-art control strategies designed for lower limb exoskeletons are reviewed that show the application of human motion sensing.

“…One of the new clinical techniques to measure balance, gait and pathology parameters is the use of ultrasonic sender and receivers. Ultrasonic sensors have been used to measure short step and stride length and the distance between feet (27,28). With the knowledge of the speed at which sound travels through air, ultrasonic sensors measure the time needed to send and receive the wave produced, as it is reflected on an object.…”

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.
