Development of a telerehabilitation system for training physiotherapists in rural areas.

The purpose of this study was to assess the effectiveness of transmitting moving pictures via the Internet for processing by a three-dimensional motion analyser. The movements of two patients were filmed by a videocamera and transmitted from a hospital to a university department of physiotherapy. After advanced analysis using a three-dimensional motion analyser, physiotherapists prepared a treatment plan. The transmitted moving pictures were clear enough for analysis. The physiotherapists in the hospital were satisfied with the results of the motion analysis and found the guidance from an expert physiotherapist valuable. In the future, a large number of video-sequences could be transmitted during the night, stored at the university and then analysed later by an expert physiotherapist.

Image manipulation: digital versus analog.

A conceptual difference between "analog" and "digital" digitizing is reviewed. Analog and digital type image filing systems are discussed from a comparative point of view: The analog type is advantageous in the number of recordable images, the recording and reproducing speed, and the ability to record a moving picture, while the digital type, in which images are digitized when recorded, is capable of reproducing a higher quality image that does not deteriorate when copied repeatedly. It has the advantage that it easily interfaces with computer systems. As technology developed to compensate for the drawbacks of the digital type systems, image data compression was introduced. Finally, the possibility for recording a moving picture in a digital type system is discussed.

The origins of scientific cinematography and early medical applications.

OBJECTIVE: To examine the neurologic cinematographic contributions of Gheorghe Marinescu. BACKGROUND: Near the end of the 19th century, cinematography developed and was immediately recognized as a new technique applicable to medical documentation. After studying with several prominent European neurologists and deeply influenced by Jean-Martin Charcot, Marinescu returned to Bucharest in 1897 and applied moving picture techniques to the study of neurologic patients. METHODS: The Romanian State Archives were researched for original Marinescu films, and related publications were translated from Romanian and French. RESULTS: Between 1899 and 1902, Marinescu perfected the use of cinematography as a research method in neurosciences and published five articles based on cinematographic documents. He focused his studies particularly on organic gait disorders, locomotor ataxia, and hysteria. He adapted Charcot's method of lining up several patients with the same disorder and showing them together to permit appreciation of archetypes and formes frustes. He decomposed the moving pictures into sequential tracings for publication. He documented treatment results with cases filmed before and after therapy. Processed and digitized excerpts of these films accompany this manuscript. CONCLUSIONS: Marinescu's cinematographic studies led to several original contributions in clinical neurology. Remaining film archives include examples of many neurologic diseases, his examination techniques, and the working medical environment of the young founder of the Romanian school of neurology.

[The effects of concomitant pictorial information on the memory and comprehension of story].

The present study was carried out to examine the effect of movement and coloring of concomitant pictures on children's story learning. The story was Hans Christian Andersen's HINAGIKU (daisy), which was 47 sentences long. In relation to the story, the subjects in experimental groups were presented the static or moving pictures by means of picture-card show or animation video. Those pictures were colored or uncolored. Immediately after the story learning, the subjects were given verbative recall and inferential tests. The 156 second graders were assigned to one of four experimental groups and a control group (without pictures). The main findings were as follows; (1) The coloring of picture had facilitative effects on the verbative recall of story. This result indicates that clear visual imagery improved the memory of story. (2) The moving of picture facilitated the inferential test performance. This result indicates that the movement of picture clarified the story context and gave a lot of cue information to comprehend story.
