It was reported by the author that a system named "ADL fiinger strain-gauge system" is useful for kinesiological analysis of fine finger activities included in usual ADL items and that this system was used for analysis of writing activities. At that study, several results were obtained about handwriting activities. Similar study were also obtained in feeding and scissoring activities. The study of feeding activities revealed that; 1. The pressure between each of 3 fingers and the tea-spoon is 51g on an average. 2. This pressure is about 1/1000 of total hand pressure, 1/200 of pinch-pressure between the thumb and index finger, 1/5 of total writing pressure, and 1/2.5 of finger-pressure during handwriting. 3. Minimum pressure for spooning is about 23 g on an average. 4. Maximum pressure for spooning is about 100 g on an average. 5. Chop-stick activities was also investigated, but the present method of investigation was found inadequate for this purpose. 6. and some others. In the study of scissoring activities, western type scissors and Japanese ones were compared and similar results with those of feeding activities were obtained.
