[Purpose] The purpose of this study was to implement for occupational therapy students and examine the learning effect a one-day dementia education program. [Subjects and Methods] The subjects were those who were able to participate in participate fully in the one-day program and submit assignments among the third-year occupational therapy students attending. The students prepared the first and the final reports for the case study from the dementia education program. These reports were scored by rubric evaluation and the learning effect was examined by comparing them by the statistical method. We also surveyed students' learning satisfaction and participation by questionnaire. [Results] A significant difference was found from the comparison of the initial and the final reports submitted. From the questionnaire, both learning satisfaction and participation were good. [Conclusion] The learning effect in the dementia education program was suggested.

[Purpose] The purpose of this study was to compare Eccentric Stretching (ES) and Static Stretching (SS) to see if it could be a useful technique to prevent performance degradation． [Method] The range of motion (ROM) of the ankle dorsiflexion before and after the intervention of the two methods of stretching， ES and SS， and the control without stretching(NS)， targeting the ankle plantar flexor muscles of 18 healthy male university students． And the ankle plantar flexor muscle strength and vertical flight were compared． [Results] In ROM， SS and ES were significantly higher after the intervention． The ankle plantar flexor muscle strength was significantly lower in SS and significantly higher in ES． In vertical jump， ES improved slightly after the intervention， but no significant difference was observed． [Conclusion] It was suggested that the ES used in this study may be an effective technique to prevent the performance deterioration pointed out in SS．

[Purpose] The purpose was to investigate the effect of the joint mobilization technique focusing on the kinematic movement of the ankle on the action of squat down and the range of motion of the ankle dorsiflexion.[Subject] 20 healthy subjects were evaluated as incapable of squatting down by a preliminary survey. [Methods] The measurement items were the floor-buttock distance and the ankle dorsiflexion range of motion. The measurement was performed twice with an interval of 4 days or more. [Result] A significant difference was found in the improvement rate between the floor-buttock distance before and after the joint mobilization. [Discussion] Regarding the decrease in the distance between the floor and buttocks, the joint mobilization caused loosening of the joint capsule behind the ankle joint, and the function of facilitating weight transfer to the forefoot affected the improvement of squatting down.

[Purpose] The purpose of this study is to verify the Heel raise motion using the newly developed toe-prompting training device from an electromyographic point of view. [Measurement method] Measure the amount of muscle activity for 5 muscles, the short toe flexor muscle, the medial head of the peroneal abdominal muscle, the anterior tibial muscle, the medial broad muscle, and the semi-tendon-like muscle. We compared and examined in. In the second report, the Heel raise operation was changed from a 1-second rhythm to a 5-second rhythm. [Results] I The muscle activity of the flexor digitorum profundus, tibialis anterior, and vastus medialis muscles tended to be higher in all phases with spring than without spring. However, the amount of muscle activity in the medial gastrocnemius tended to be small in all phases. [Conclusion] It was suggested that the Heel raise operation using the toe-standing facilitation exerciser is an exercise device that can raise the Heel while suppressing the amount of muscle activity in the medial gastrocnemius muscle compared to the one without the spring.

[Purpose] In this study, we focused on the light rubbing method and the strong rubbing method in manual therapy, and devised and fabricated a device for measuring the strength in order to verify the effectiveness of these techniques. The purpose of this paper is to introduce the specifications of this device and to report its usage. ［Specifications of this device］The device is made of wood and consists of a box and a bottom plate. Two cuffs of　electronic sphygmomanometer are installed inside the outer frame to measure the downward pressure. The bottom plate had a spare width of 4 cm on the left, right, front and back from the box part, and was used for installation (vise fixation) with the pedestal. [Measurements]The two blood pressure cuffs in the box were inflated to 30 mmHg, and the Passing board was placed above the cuffs. The performer performed the light rubbing method and the strong rubbing method in a manner that the performer moved the palmar base of the hand back and forth 2 times/second on the Passing board. [Reliability and validity of this device] The reliability and validity of this device are considered to be the problems of this study and will be addressed in the future.

[Purpose] The purpose is to classify the impossible group and the possible group for the action of squat down， and to examine the possibility of the action of squat down and the comparison of gender differences. [Subject] 304 healthy people (male students: 198， 19 ± 1 years old， female students: 106， 19 ± 1 years old)． [Methods] The action of squat down was defined based on the previous study， and the subjects were made to form a pair in pairs， one of them squatted down as a subject， and the other was evaluated as an evaluator. [Result] The Share of impossible group is 22.4%. No significant difference was found in the comparison between the possibility of squatting down and the gender difference. [Discussion] In the definition of squatting down in this study, the knee joint was flexed on the sagittal plane, which suppressed the increase in external rotation of the hip joint and led to the result that no significant difference was observed in gender.

Neuromuscular Joint Facilitation (NJF) is a new therapeutic exercise based on the knowledge of kinesiology, that integrates the facilitation element of PNF and the joint composition movement, and improves the movement of the joint by passive exercise, active exercise, and resistance exercise. The theoretical system, treatment technology, indications, research results, etc. of NJF knee joint approach　will be introduced.
