Introduction: Walking and running, both forms represent a movement of the body from one position to another position. It is important to know all the characteristics and processes of the normal gait pattern of walking and running, because only then can we identify gait abnormalities in amputees in order to eliminate them or improve the gait pattern during prosthetic treatment. Purpose: We aimed to investigate the biomechanics of walking and running with accelerometers in transtibial amputee. We also wanted to investigate the use of the RunScribe accelerometer system for walking and running in transtibial amputees Methods: We performed the walking and running measurements on one subject. We attached the accelerometers in on the dorsal area of the foot and he had to walk and run 400 m with the prosthetic feet Elite Blade and Blade XT. We had to export the results we got from the RunScribe application and discuss them. Results: We examined stride length and step lenght, stance time, maximum pronation velocity, footstrike type, and vertical impact force. We found that there is not much difference in stride and step lenght, stance time between intact and prosthetic foot, and there is also a small difference in motion with different prosthetic feet. The greatest disharmony between the legs is in the vertical impact force, maximum pronation velocity, footstrike type and flying time with Blade XT prosthetic foot. Discussion and conclusion: This was the first time RunScribe inertial measurement unit was used to evaluate walking and running biomechanics in transtibial amputee, as RunScribe is primarily designed for healthy runners. We also used two different prostheses, the feet Elite Blade and Blade XT. Spatiotemporal parameters are rarely measured with accelerometers in prosthetics. Common advantages for wearable inertial measurement devices in amputees are their small size, portability, low cost, unlimited time and place for measurement, measurements outside the laboratory, ease of use, smartphone applications. The described measurements that can be performed with RunScribe can help optimize prosthetic fitting, dynamic alignment of prostheses, and selection of prosthetic components.
