“…H. F. Alamiri, 2020). And the relationship of this to the achievement, in order to reach the best biomechanical conditions for the position of the legs and the appropriate momentary thrust, which is associated with achieving the best angle momentum for the parts of the body contributing to performance and to ensure that the speed and angular momentum do not decrease before and after the launch of the disc, and the researchers were keen to obtain data using technical devices that are characterized by accurate measurement, and these devices (Dyna foot) (Sironić, 2017) which is a device for analysis in detecting the values of the amount of pressure, force exerted and contact time and the extent to which these variables are used to identify errors and develop the necessary exercises and develop appropriate special exercises for them (Holzman et al, 2007), and this is what implies the importance of research as a serious attempt to identify the current mechanical situation of throwing to weaking and studying the smallest details of this case, and taking advantage of modern scientific devices and tools to indicate weaknesses and strengths and diagnose errors on the basis of which special exercises are built without neglecting any important aspects of the performance mechanism (Krishnan et al, 2020), the study aimed to identify some biomechanical variables of the fingerprint and the completion of the research sample, using the Dyna foot system through an analytical study of discus throwing for applicants. , and the researchers assumed that there is a significant correlation between the momentary force exerted by the two legs when placing the throw with the biomechanical variables of the throwing performance.…”

The effectiveness of discus throwing is one of the activities that require special physical abilities and mechanical conditions aimed at achieving the best horizontal distance for this competition, and performance is associated with achieving the highest instantaneous strength and rapid strength in the muscles of the working body, especially the trunk, legs and arm shooting, and the researchers believe that the amounts of these forces can give a good indication of what is supposed to be achieved from the integration of skill performance, which aims to achieve the highest speed at the end of the arm shooting, so the control of the values of these The forces, especially the two legs through the device (Dyna foot) can help the researcher to make the right decision if these forces are optimally exploited to achieve integration of performance, as well as monitoring the amount of pressure and force affecting the weight of the thrust and the extent to which these variables are used to identify errors and develop solutions to improve the exertion of the appropriate special force for them, and the researchers assumed that there is a significant correlation between the momentary force exerted by the two legs when placing the throw with the biomechanical variables of the throwing performance, The researchers used the descriptive analytical approach to process data and information related to the nature of the problem. The researchers chose a sample of Iraqi heroes with a number (4) elite disc shooters, and the researcher concluded that there is a significant correlation between the momentary force and the pressure exerted by the feet and the momentary force in the trunk and arms with some biomechanical variables to perform in the discus throw, as well as between the rapid strength of the legs with the variables of the disc launch.

“…Tu et al introduced functional electrical stimulation (FES) to supplement the exoskeleton's assistance for ankle joint [12]. Krishnan et al proposed a parallel PM-driven ankle rehabilitation robot (ARR) with the top moving platform supported by a central strut between the top and the bottom [13]. Though this robot covers the 3-DOF movement range, it is difficult to provide effective assistance for patients due to a lack of rigid connection to the lower limb [11].…”

Ankle dysfunction is common in the public following injuries, especially for stroke patients. Most of the current robotic ankle rehabilitation devices are driven by rigid actuators and have problems such as limited degrees of freedom, lack of safety and compliance, and poor flexibility. In this paper, we design a new type of compliant ankle rehabilitation robot redundantly driven by pneumatic muscles (PMs) and cables to provide full range of motion and torque ability for the human ankle with enhanced safety and adaptability, attributing to the PM's high power/mass ratio, good flexibility and lightweight advantages. The ankle joint can be compliantly driven by the robot with full three degrees of freedom to perform the dorsiflexion/plantarflexion, inversion/ eversion, and adduction/abduction training. In order to keep all PMs and cables in tension which is essential to ensure the robot's controllability and patient's safety, Karush-Kuhn-Tucker (KKT) theorem and analytic-iterative algorithm are utilized to realize a hierarchical force-position control (HFPC) scheme with optimal force distribution for the redundant compliant robot. Experiment results demonstrate that all PMs are kept in tension during the control while the position tracking accuracy of the robot is acceptable, which ensures controllability and stability throughout the compliant robot-assisted rehabilitation training.
