概要:
This study was performed to clarify the outcome of reflex sympathetic dystrophy (RSD) ―especially in relation to its typ

es, symptomes and findings in 108 patients who were diagnosed as RSD by the author's criteria and treated in the Department Orthopaedic Surgery Niigata University School of Medicine or its affiliated hospitals during the period from 1972 to 1983. RSD was divided into three types, i.e. causalgia caused through peripheral nerve injury (37 cases), minor causalgia caused through minor trauma to an extremity (62 cases) and minor causalgia developed without any trauma (9 cases). The interval between the trauma and onset of RSD was on an average 3 weeks in causalgia and 5 weeks in minor causalgia with or without trauma. 19 out of 37 cases of causalgia were cured within one year, whereas majority of cases of minor causalgia were cured within 9 months. One of the two cases of causalgia associated with brachial plexus injury which resisted stellate ganglion block and other treatments was cured by upper thoracic sympathectomy and the other with peripheral perivascular sympathectomy. 65 out of 108 cases, in which females had been recognized more than males, were disclosed as being associated with abnormal personality by psychoanalysis according to Tokyo University Personality Inventory. The tendency was noted to take more time for cure in patients with abnormal personality which alluded to psychic involvement in RSD. Early diagnosis and early appropriate treatment were thought essential to cure this difficult condition.

概要:
In this work, a grip force dynamometer composed of pressure-sensitive conductive rubber was used to study the sensibility characteristics for grasping of a solid cylinder. The mechanical and physical parameters for ten normal male subjects
…
(aged between 22 and 26) were measured at various cylinder diameters and weights. In addition, a direct linear transformation technique employing a video camera system was developed to determine the finger joint motion used to grasp the cylinder. The experimental results showed that the frictional coefficien of a palm is significantly dependent upon the deform ability of the soft tissue of the palm. It was found that the optimum cylinder diameter for easy grasping is nearly equal to the inner grip diameter formed by the fingers.

概要:
This paper is concerned with biomechanical analysis of the motion characteristics for grasping a solid cylinder. Contact pressure and surface electromyogram (surface EMG) of muscle flexor digitorum superficialis during

grip motion were measured using a contact pressure measurement system with pressure-sensitive conductive rubber sensors and an electromyograph, respectively. In addition, direct linear transformation (DLT) technique with a video camera system is used to analyze three-dimensional joint motion of fingers. It was found that the tips of middle finger, ring finger and thumb are mainly used to stably grip the cylinder. The experimental results also showed that grip pressure increased with an increase in the weight of the cylinder with a constant diameter.
