This paper attempts to estimate the differences between the static optimization solution and the exact one. A multibody biomechanical model of a leg of the human being is presented. The model is based on natural coordinates. It is applied to the case of raising of the leg to solve individual muscle distribution problem. Some parameters of the obtained optimal solution are compared to the ones received through the solution of inverse dynamics problem.

A Device for Preventing Occupational Diseases of Lower Legs

Physiological processes characteristic of the fatigue of legs mainly appear when the worker’s activity requires standing. If the processes are intensive and regular, various diseases of legs, such as varicose veins and musculoskeletal disorders of legs and feet, can develop. Therefore, methods of reducing the fatigue of legs are important in occupational health protection. Air jet massage technology was developed and an appropriate massage device was built by the authors. The massage head turning around the lower leg and moving up and down gradually covers the leg’s surface. To determine the efficiency of the massage, fatigue processes were studied. These studies showed that jet massage effectively reduces both the subjective and objective fatigue symptoms. The device is convenient for use in industry, services, and at home.
