Streszczenie:
We report several experiments directed at the ability of humans to perceive the spatial orientation of occluded objects, to position an occluded limb relative to targets or directions in the environment, and to match the spatial orientations of occluded contralateral limbs. Results suggest that each of these abilities is lied to the inertial eigenvectors of each object or limb, which correspond to the object's or limb's principal axes of rotational inertia. Discussion focuses on the dynamic nature of proprioception, the importance of physical invariants for perception, and the relation of invariants to hypothesized frames of reference for proprioception and motor control. It is suggested that the detection of invariants revealed through movement is a major mechanism in kinesthetic perception involving intact limbs, neuropathic or anesthetized limbs, prosthetic devices, and hand-held tools and implements. The inertia tensor is identified as one such invariant.

Streszczenie:

Infrainguinal bypass grafting is an established method in the treatment of patients with femoropopliteal and crural occlusive disease leading to critical lower limb ischaemia (CLI). However, complications related to surgical procedure are not negligible and percutaneous transluminal angioplasty (PTA) has emerged as an alternative. The present thesis covers some aspects of infrainguinal PTA in patients with chronic severe lower limb ischaemia.

The records of 217 patients undergoing 272 PTA procedures at various infrainguinal arterial segments were analysed. The indication for intervention was subcritical ischaemia in 76 limbs and critical ischaemia in 177 limbs. The role of duplex ultrasound examination in the selection of patients for PTA was retrospectively evaluated following a prospective validation of the method against angiography.

A technically successful PTA was achieved in 89%. The overall 30-day mortality was 2.7%. No patient underwent amputation directly related to failed PTA. The primary success rates at 12 and 60 months following femoropopliteal PTA were 40% and 27% compared, to 51% and 36% in limbs undergoing crural artery PTA. Primary success rate in limbs with SFA occlusion longer than 5 cm was only 12% after 5 years, compared to 32% if the occlusion was equal or less than 5 cm in length (p<0.01). In patients undergoing distal PTA through patent infrainguinal grafts, the primary and primary assisted patency rates at 3 years were 32% and 53%, respectively. The sensitivity of duplex scanning in the selection of lesions for PTA was less satisfactory in the popliteal and crural arteries compared to the superficial femoral arteries.

In conclusion, the results of infrainguinal PTA performed for treatment of subcritical or CLI seemed to be inferior to the results of surgical interventions reported in the literature. However, due to the fact that the PTA procedure does not preclude the performance of bypass grafting, it might be an alternative to surgical intervention in limbs with stenotic or short occlusive lesions.

Humans possess the remarkable ability to control their four natural limbs in a voluntary, accurate and independent manner. The simultaneous use of two or more limbs allows humans to learn and robustly perform a wide range of complex tasks. Since the use of multiple limbs enables humans to master advanced motor skills, it would be interesting to study whether having additional limbs would enable users to expand their skill set beyond its natural limits. Inspired by this vision, we propose a new form of human augmentation: a wearable robot that augments its user by providing him with an additional set of robotic limbs. We named this new device Supernumerary Robotic Limbs (SRL). However, humans have never had the possibility to control additional, powered limbs besides their natural arms and legs. The main theme of this thesis, besides realizing a prototype of the robot and proving its usefulness in realworld tasks, is demonstrating that humans can voluntarily control additional limbs as if they were a part of their own body. We realized a lightweight (3.5 kg), comfortable prototype of the SRL that can be easily worn by an unassisted user. Two robotic limbs can assist the user in both manufacturing and locomotion tasks. We created control strategies that take advantage of the independence of the robotic limbs, enabling them to provide optimal assistance in specific tasks such as weight support, body stabilization, using powered tools, sitting/standing and dynamic walking. Finally, we developed an EMG-based control interface that enables users to voluntarily control the motion of the robotic limbs, without interfering with the posture of the rest of the body. The new augmentation technology presented in this thesis opens up new possibilities in the field of wearable robotics. The voluntary control of additional robotic limbs falls within the range of motor skills that humans can learn, and enables the acquisition of a new set of complex skills that would not be achievable using only the natural body..

Overhead tasks such as those frequently found in aircraft manufacturing pose health risks to the workers due to the strain imposed on the shoulders. To reduce the risk of injury, a set of supernumerary robotic limbs (SRL) were designed to perform these overhead tasks. The SRL is designed with limits in the hardware and software to protect the human and prevent collisions between robot and operator. The arms are designed to have a workspace above and in front of the head of the user free from singular configurations so the robot is free to operate where the tasks will be performed. To further protect the human, the mount that attaches the SRL to the shoulders was redesigned to be lighter and to better distribute the load. In this manner, the shoulders will become less fatigued from the static load of carrying the SRL To complete the task of positioning cables and routing them through the ceiling of an airplane, a winch end effector was designed to latch onto the fuselage arches and pull the cable through these arches. In order to control the SRL, the concept of principal components analysis was used to reduce the input space. This concept was specifically used to map the motion of the operator's hands onto the appropriate speed for the winch motor to operate. In this manner, the winch would pull the cable at the same rate that the human fed the cable. The human would then be able to control the speed of the winch simply by executing the task at whatever pace they so desired.

Streszczenie:
Passive limbs can be introduced into the design of parallel mechanisms to provide constraints, generate decoupled configuration, bear full or partial weights and/or payloads, separate constraints from the actuations, decrease the required actuating forces of active limbs, and even increase the stiffness and accuracy of the whole system. Currently, there is still no systematic study on the utilization of passive limbs. The available parallel mechanisms having one passive limb were developed mainly based on intuition and ingenuity. In this paper 4-DOF and 5-DOF parallel mechanisms with passive limbs are investigated in terms of type synthesis. Based on the distribution of wrench system among the active limbs and passive limbs, a full-scale criterion is developed for effectively and efficiently synthesizing all kinds of 4 & 5-DOF parallel mechanisms with one or more passive limbs. All 9 categories of the 4-DOF and 2 categories of 5-DOF parallel mechanisms with passive limbs are synthesized and exemplified through kinematic diagrams merely using independent constraints. Several nonoverconstrained 4 or 5-DOF parallel mechanisms with one or two constraining passive limb are presented.

Streszczenie:
Most existing lower limb orthosis use actuators and active controller to guide the motion of human lower limbs. Actuators with relatively large power are usually required to compensate the gravity effect of the human lower limbs, even for a normal walking. Hence, design of an orthosis for the weight balance of human lower limbs is desired. For the motion compatibility, the human hip joint is treated as a planar pair and the knee joint as a revolute pair. As a consequence, while the lower limb is in motion, the exact positions of the mass centers of the human lower limbs cannot be obtained. Hence, in this work, topological synthesis of the orthosis mechanisms, which can trace the mass centers of the human thigh and shank, respectively, is implemented. The weight balance of the human lower limbs is achieved by fitting a minimum number of zero-free-length springs. Based on the anthropometric parameters, dimensions of the lower limb orthosis is determined and the proposed design is justified by the simulation executed by the software of ProEngineer. Finally, a first generation prototype is built.

Streszczenie:
The Multi-Appendage Robotic System (MARS) is a hexapedal robotic platform capable of walking and of performing manipulation tasks. Each of the six limbs of MARS incorporates a three-degree of freedom (DOF), kinematically spherical proximal joint, similar to a shoulder or hip joint, and a 1-DOF distal joint, similar to an elbow or knee joint. The generation of walking gaits for such robots with multiple limbs requires a thorough understanding of the kinematics of the limbs, including their workspace. Since the entire limb workspace cannot be used in a statically stable alternating tripedal gait for such a robot, a subset of the general limb workspace is defined to be used for walking gait generation algorithms. The specific abilities of a walking algorithm dictate the usable workspace for the limbs. Generally speaking, the more general the walking algorithm is, the less constricted the workspace becomes. In this paper we develop the workspaces for the limb of MARS in the knee up configuration, which range from simple 2D geometry to complex 3D volume, and analyze its limitations for use in walking on flat level surfaces. Next we discuss the case when the robot body is not parallel to the ground. The results from this paper can be applied to the development of walking gait generation algorithms.

During walking, human lower limbs accelerate and decelerate alternately, during which period the human body does positive and negative work, respectively. Muscles provide power to all motions and cost metabolic energy both in accelerating and decelerating the lower limbs. In this work, the lower-limb biomechanics of walking was analyzed and it revealed that if the negative work performed during deceleration can be harnessed using some assisting device to then assist the acceleration movement of the lower limb, the total metabolic cost of the human body during walking can be reduced. A flexible lower-limb exoskeleton was then proposed; it is worn in parallel to the lower limbs to assist human walking without consuming external power. The flexible exoskeleton consists of elastic and damping components that are similar to physiological structure of a human lower limb. When worn on the lower limb, the exoskeleton can partly replace the function of the lower limb muscles and scavenge kinetic energy during lower limb deceleration to assist the acceleration movement. Besides, the generator in the exoskeleton, serving as a damping component, can harvest kinetic energy to produce electricity. A prototype of the flexible exoskeleton was developed, and experiments were carried out to validate the analysis. The experiments showed that the exoskeleton could reduce the metabolic cost by 3.12% at the walking speed of 4.5 km/h.

Commercial prosthetic limb development for transfemoral amputees has historically focused on legged locomotive function with energetically dissipative or conservative limbs. While such passive devices are effective at approximating the mechanics of the knee during level walking and stair/slope descent, the inability of these limbs to impose net positive power prevents amputees from executing a number of activities of daily living. Activities such as ascending slopes, ascending stairs, and jumping require net positive power outputs that are not fully realizable with current prosthetic leg technology [1–3]. While functionality has improved with microprocessor-based passive limbs [4], amputees continue to exhibit increased metabolic demands and non-anthropomorphic asymmetric gait [5].

Wireless inertial sensors were used to measure acceleration and angular velocity during multi-joint movements of both upper limbs. In this research only wrist’s pronation-supination movements in sagittal plane were analysed. Obtained results shows that dance therapy has a positive influence on improved biomechanics of upper limbs and general decrease of UPDRS score.

Based on the newly invented reconfigurable Hooke joint which changes the joint property, this paper investigates synthesis of limbs using the new joint based on constraint analysis. The procedure of the limb synthesis is put forward to fully use the property of the new joint for generating the reconfigurable limbs. Further, the paper presents a way of synthesising the parallel mechanism with metamorphic characteristics by starting from the aim at mobility-change. This is then integrated into the forward-based limb synthesis. A general procedure is proposed and applied to construct two classes of metamorphic parallel mechanisms. Their topological configuration change is investigated by examining the constraint change stemming from the phase alteration of the reconfigurable Hooke joint.

In women’s artistic gymnastics, the balance beam belongs among the disciplines with the heaviest lower limbs load. The aim of our research was to disclose a lower limbs weekly load volume regarding load asymmetry, and to determine the take-off and landing reaction forces between landing ground and foot in selected gymnastic elements. In 9 female artistic gymnasts of junior and senior category one training week was video-recorded and analysed. The reaction forces were measured using 5 Bertec force plates in one female Czech nation-al team member. Based on the training video recordings 12 jump and acrobatic elements were analysed. Among the total of 422 recorded take-offs and landings 41% were performed from both legs, (BL), 44.5% from one lower limb (HL) and 14.5% from the other lower limb (LL). The maximum reaction force of the landing ground during take-offs was 2.4 BW in av-erage, 3.1 BW in landings. In asymmetrical elements, one leg was loaded three times more (538.3 BW) than the other (174.1 BW) in one training day in total. We recommend to record the load asymmetry in the course of the gymnastic trainings in order to choose and person-alise the appropriate regeneration process and compensational exercise.

Streszczenie:
This paper introduced a new metamorphic parallel mechanism consisting of four reconfigurable rTPS limbs. Based on the reconfigurability of the reconfigurable Hooke (rT) joint, the rTPS limb has two phases while in one phase the limb has no constraint to the platform, in the other it constrains the spherical joint center to lie on a plane. This results in the mechanism to have ability of reconfiguration between different topologies with variable mobility. Geometric constraint equations of the platform rotation matrix and translation vector are set up based on the point-plane constraint, which reveals the bifurcated motion property in the topology with mobility 2 and the geometric condition with mobility change in altering to other mechanism topologies. Following this, a unified kinematics limb modeling is proposed considering the difference between the two phases of the reconfigurable rTPS limb. This is further applied for the mechanism modeling and both the inverse and forward kinematics is analytically solved by combining phases of the four limbs covering all the mechanism topologies.

In this paper, we apply screw theory to the type synthesis of compliant parallel mechanisms (PMs). Compliant PMs are formed by a moving stage supported by three or more limbs each of which is a serial chain of flexure joints and rigid bodies. They achieve movement through the deformation of flexure joints and have been widely used in precision machinery. As an important task in the conceptual design stage, the goal of type synthesis is to determine the chain of each limb as well as their relationship when they are assembled in parallel for a prescribed motion pattern. Our approach starts with a category of commonly used flexure primitives and flexure elements whose freedom and constraint spaces are characterized by twists and wrenches in screw theory. Following the well-studied synthesis procedure for rigid body PMs, we propose a synthesis procedure for compliant PMs via screw theory. This procedure consists of four basic steps: decomposition of the screw system of the constraint space, type synthesis of limbs, assembling limbs and design of flexure joints. As an example, we demonstrate the procedure for synthesizing compliant PMs for three degree-of-freedom (DOF) translational motions. Tables of limbs, types and geometric conditions for the assemblies of these limbs are presented. The paper provides a catalogue of compliant PM designs with three translational motions. At last, we provide a case study of applying finite element simulation to validate one of the synthesized designs.

Streszczenie:
Review question / Objective: The purpose of this review is to determine the efficacy and safety of acupuncture on diabetic peripheral neuropathy (DPN) pain compared with analgesics or sham acupuncture.Randomized controlled trials are the only types of studies included in this review. Condition being studied: Diabetic peripheral neuropathy (DPN) is a common complication of type 1 and 2 diabetes. It is also the main cause of lower limb amputation and disability in patients with diabetes. Epidemiological evidence shows that up to 50% of patients with diabetes developed neuropathy during their long-term course of disease. The cause of DPN is not completely clear, but older age, longer diabetic duration and worse postprandial glucose control has been proved to be closely related to DPN. Distal symmetric polyneuropathy is the most typical manifestation of DPN, and about 10% to 30% of the affected patients may experience symptoms of neuropathic pain. Pain can be described as burning pain, electrical or stabbing sensations, parasthesiae, hyperasthesiae, and deep aching pain of the feet and lower limbs at night. This irreversible and unbearable pain greatly affects patients' sleep and quality of life.
