Diagnosing Male Unilateral Upper Limb Lymphedema: Determination of Normatively Determined Thresholds Using Bioimpedance Spectroscopy

Ergonomic assessment systems were created for possibility of prediction and risk detection at workplace. Ergonomic assessment system EAWS (European Assembly Work-Sheet) includes assessment of body postures, action forces, weight of carrying loads and frequently recurring upper limb loads assessment. Assessment of action forces (forces generated by upper limb defined by EAWS) is problematic and there is a lack of means for effective assessment. This paper deals with design of electronic device for assessment of action forces generated by upper limb defined by EAWS with using of thin film FSR (force sensing resistor). The paper deals with identification of upper limb areas, where the generated forces are important for assessment by EAWS, deployment of sensors in identified areas, calibration of FSR sensor with regard to simply program implementation in microcontroller, determination of action forces in every by EAWS defined action force application and construction of sensing and evaluating part of electronic device.

The main objective of the study consists in determination of the most appropriate sampling rate of the measurements in instrumented kinematic analysis of the upper limb movements. The measuring system involved in the study is Zebris CMS-HS Measuring System, whose configuration was defined by ultrasound markers attached to specific body sites. The sampling rate interval was set from 10 to 25 Hz, according to the system’s range of frequencies. The kinematic parameters which have been analyzed are shoulder and elbow flexion-extension and shoulder abduction-adduction. A comparative kinematical analysis of the angle variations of flexion-extension and abduction-adduction in shoulder joint and flexion-extension in elbow joint was performed for both left and right upper limbs at each sampling rate.

The paper presents the determination of the constraint forces acting in the human upper limb joints, using the inverse dynamic analysis procedure based on Lagrange multipliers method. The kinematics parameters time variation laws were established through experiments for the considered driving joints. The constraint forces time variation laws define the database for the dynamic analysis using the finite element method and for dimensioning an exoprosthetic system for later rehabilitation of the human upper limb motion.

Human Upper Limb

Motion control is complicated for people having traumas or neurological diseases. An underlying assumption in our work is that the motion of healthy people is optimal with respect to positioning accuracy, movement response, and energy expenditure. In this paper, a new approach for determination of the human upper limb mass-inertial characteristics is presented by using the 3D geometrical mathematical modeling analysis approach. Two examples will be given to illustrate the main features and advantages of the proposed design concepts. The objective of the work presented in this paper is a determination of the mass properties of a two joints human upper limb manipulator. Results are aimed to have application in an exoskeleton design, the design of manipulation system and external manipulation system, serving people with some motion difficulties, as well as in sport and rehabilitation.
