Abstrakt		Muscle dynamics were measured by means of two measurement systems. The first system is based on a mechanical brace constructed to record the isometric joint torque (1) and the second system is based on the detection of radial globulisation of the muscle belly due to muscle contraction (2). Both measurements were done on the tibialis anterior muscle and simultaneously on the ankle joint. The same methods were also applied in measurements of the isometric hip extension that was realized by a strain gauge sensor and in globulisation of the muscle gluteus maximus with the help of magnetic displacement sensor. The results show significant differences in dynamic responses between healthy individuals and patients with an amputated side. A significant difference in the slope of the response was also obtained between records of patients with progressive muscular dystrophy and healthy people. For both muscle groups twelve healthy subjects were considered in order to establish the statistical patterns. These results are useful primarily as a reference for the selective evaluation of the changes of muscle characteristics due to various pathology (3,4). The aim of the present study was to find a simple method for measuring the relative force and dynamic properties of musculus gluteus maximus. Musculus gluteus maximus is not important in normal walking but in above-knee amputees it remains the only uninterrupted hip extensor. It is also important for control of prosthesis (5).
