Tourniquet-use has been described in litera- ture as a surgical factor leading to increased post-operative hidden blood loss total knee arthroplasty (TKA). The hypothesis for this retro- spective study was that low-pressure tourniquet TKA would offer the benefits of surgery without potential negative effects on late after procedure. Therefore, evaluated (TBL) and (HBL) with or tourniquet. We re...

conclusions the study indicated advantages of this modified bier's block compared to the traditional one including ability to perform surgery on upper limb bones and considerable pain relief at surgical and tourniquet sites during the operation until one hour thereafter. results this study showed the presence of analgesia at surgical and tourniquet sites during the operation in 96% of patients,...

In this article, a soft robot arm that has the ability to twist in two directions is designed. This continuum inspired by twisting movements of human upper limb. novel arm, contractor pneumatic muscle actuators (PMA) are used parallel, and self-bending contraction actuator (SBCA) laid between them establish movement. The proposed additional features, such as contract bend multiple directions. k...

Abstract Individual manipulators are limited by their vertical total load capacity. This places a fundamental limit on the weight of loads that single manipulator can move. Cooperative manipulation with two arms has potential to increase net capacity overall system. However, it is critical proper sharing takes place between arms. In this work, we outline method utilizes mechanical intelligence ...

The trajectory control of a pneumatically driven robot arm resembing a skeletal muscle system is studied. The arm dynamics have been shown to be hysteretic and signiicantly changing in time due to external innuences (Hesselroth et al., IEEE Systems, Man and Cybernetics, in press) thus requiring an adaptive controller. A highly adaptive feedback algorithm is suggested and shown to control accura...

Soft robot arms possess unique capabilities when it comes to adaptability, flexibility, and dexterity. In addition, soft systems that are pneumatically actuated can claim high power-to-weight ratio. One of the main drawbacks of pneumatically actuated soft arms is that their stiffness cannot be varied independently from their end-effector position in space. The novel robot arm physical design pr...

A neural map algorithm has been employed to control a five-joint pneumatic robot arm and gripper through feedback from two video cameras. The pneumatically driven robot arm (SoftArm) employed in this investigation shares essential mechanical characteristics with skeletal muscle systems. To control the position of the arm, 200 neurons formed a network representing the three-dimensional workspace...

Sinclair and Hinshaw (1951) reported that ischaemic tingling was diminished or absent in patients with spinal or cerebral lesions causing defective tactile sensibility, and suggested that " It may even be that a diminution in the sensation of tingling affords a more sensitive test for such defects than standard testing methods ". However, the present work suggests that the relation between ting...
