[Purpose] This study was intended that tested effect to give to muscular strength by an electrode pasting positional difference by the Neuromuscular Electrical Stimulation(NMES) . [Subjects and Methods] Intended for 30 normal adults. For the right rectus femoris muscle, which 3 conditions of the group, we attached an electrode on the motor point (MP) direct top and another on the position of MP upper part 5cm, attached an electrode on the position of MP top and bottom for each 2.5cm, without the electrical stimulation. We measured maximal torque in angular velocity 60, 90, 180deg/sec, arrival time to setting angular velocity and compared it before and after intervention. [Results] A significant difference was found in arrival time to angular velocity 180deg after the intervention. [Conclusion] It was suggested that an electrode pasting position at the NMES intervention affected the muscle contraction speed.

[Purpose] The purpose of this study is to examine the approach to maintain community life by grasping the performance function of the community-dwelling elderly and the characteristics of work performance related to daily life.[Subjects and Methods] The subjects were 42 elderly people living in the community.The survey items were age, gender, frontal lobe function test (FAB), shortened version of self-evaluation of work (OSA-SF), dynamic balance ability (TUG), cognitive function test (MMSE), and SF-8.[Results] As for the characteristics of the secondary prevention group, the MMSE and TUG showed a significant decrease in function compared with the primary prevention group.A positive correlation was found between frontal lobe function and task performance. Furthermore, the frequency of satisfactory daily routines was low. [Conclusion] Participants in the secondary prevention program were related to frontal lobe function, task performance and satisfactory daily routine.

The purpose of this study was to investigate the effect of trunk replacement on Nordic hamstrings (NH). Seven healthy male students were selected. Three muscles, the left biceps femoris, the gluteus maximus, and the erector spinae, were measured. The normal limb position, the position of the acromion, and the lateral epicondyle of the femur were not changed, and two types of limb positions, which were slightly flexed in the hip joint, were measured by isometric contraction using a surface electromyograph. The biceps femoris and the erect spine muscle activities in the trunk compensation position was significantly lower than that in the normal posture, and the hip flexion angle and the knee flexion angle were significantly increased. NH's trunk compensatory movement was found to affect biceps femoris and erector spinae muscle activity.

[Purpose] The height of the medial longitudinal arch at rest and the height of the tibialis anterior muscle train were measured in healthy subjects in sitting and standing positions, and how the anterior tibial muscle affected the arch height The purpose was to verify whether or not to give. [Subjects and Methods] The arch height was measured for 20 legs of 10 female students using an ultrasonic diagnostic imaging system. The arch height ratio was compared before and after performing the ankle dorsiflexion exercise using a tube. [Results] No significant difference was observed in any case. [Conclusion]In this study, the arch did not change after training. However, if the arch was considered to be low, it was suggested that the dorsiflexion of the ankle may increase the height of the medial vertical arch.

[Purpose] The purpose of this study was to clarify the specificity of the effect due to differences in posture by comparing the intervention effect when toe function training was performed with standing and sitting positions. [Subjects and Methods] Healthy male adults without lower limb orthopedic disease or pain were assigned to 20 subjects in each group, and were trained three times a week for four weeks. Toe grip strength, FRT, maximum step length, and long jump were selected as measurement items. [Results] Comparison between before and after the exercise task intervention showed significant differences in toe grip strength, FRT, and maximum step length in both groups, and significant differences in standing long jump only in the standing training group. [Conclusion] The results suggest that toe function training may have specificity depending on the posture.

[Purpose] This time, we have devised and made a lower limb placercing exercise device for lower limb joint specific sensory practice. The purpose of this paper is to introduce this practice device and to introduce the method and procedure of practice. [About lower limb plaything exercise device] Side plates were installed on both sides of the wooden base, and drawer rails were installed on both side plates. A clog was attached to the inside of the 350mm drawer rail so that it could move back and forth. In addition, a target cover with a width of 20 mm was installed in front of the clogs of the training device. [Practice method] The subject wears a clog for measuring the test foot in the sitting position, and the examiner passively slides the test side leg to the target position, stops at the position, and memorizes the position. Instructs them to do so. Return the subject's lower leg to the starting position. The subject is instructed to automatically slide the lower limb to the previously memorized position, and the subject slides the clog to the target and measures the error. [Expected effects] The effects are expected as exercise therapy for measurement disorders and proprioceptive disorders of the lower limbs.
