BAN Hisayuki; ITAKURA Naoaki; SAKAMOTO Kazuyoshi; KITAMOTO Hiraku
We proposed a new interface that have two areas. One is called the input area which is located on the right and left sides of the display. The orther is called the guide area which is located on the central part of the display. The guide area is useful for search of the position of a desired character. We could almost distinguish between non-input and input-fixations. However the distinction was not perfect. So we investigated characteristic of non-input and input fixations'duration, saccadic duration and saccadic amplitude. We also investigated the effect of the saccadic characters on distinction between non-input and input fixations. We found non-input and input fixations. were almost able to separate by their duration. We suggested that it was effective for the distinction to use the saccadic characters., Japan Society of Physiological Anthropology, Feb. 2000, Japanese Journal of Physiological Anthropology, 5, 1, 17-22, English, 110002510535, AN1052804X - 同一酸性度を有する溶液刺激による味覚誘発脳波の研究

Some apparatuses stimulating the region of tongue innervated by chorda tympani nerve were well known and they were used popularly, but the apparatuses for glossopharyngeal nerve were not produced yet. In the study, the apparatus for the stimulations of glossopharyngeal nerve was trially produced. It was known that the substance of "Umami" was responded well in the tongue region innervated by glossopharyngeal nerve. The evoked potential for the stimulations of monosodium glutamate (MSG) solution which was known as substance of Umami was measured with the use of the trial stimulating apparatus. The evoked potential was detected by monopolar lead for the positions between Cz and A1 (left lobe) with the ground at Fpz. The evoked potential of MSG consisted of a positive peak wave with the latency at approximately 250 ms. The amplitudes increased and the latency decreased as the concentration of MSG increased. The evoked potential stimulating the tongue innervated by this glossopharyngeal nerve could be detected for the first time by the use of the trial apparatus., Japan Society of Physiological Anthropology, 1998, Applied human science : journal of physiological anthropology, 17, 2, 67-71, English, 1341-3473, 110002508224, AA11053183, 9611370 - Influence of sweet suppressing agent on gustatory brain evoked potentials generated by taste stimuli.

Sakamoto Kazuyoshi; Li Weiqiang
The influence of the muscle length on the distribution of muscle fiber conduction velocity (MFCV) was estimated at 3 different elbow angles (90゜, 120゜and 150゜) during the contraction of 30% of isometric maximum voluntary contraction (MVC). Surface electromyogram was recorded in the distal region of m. biceps brachii using a surface array electrode. MFCV_S at the different locations from the end-plate to the distal tendon of the muscle were measured directly using the averaging method. MFCV_S near the end-plate and the distal tendon of the muscle showed the high values, while MFCV_S in the middle region between the end-plate and the distal tendon of the muscle had low values at the same elbow angles. The mean MFCV_S in the middle region decreased when the muscle length increased during the contraction of 30% MVC. The middle region length changed when the elbow joint was extended from the elbow angle of 90゜ to that of 150゜. Although previous studies showed the influence of muscle length on MFCV for special regions (like end-plate, tendon, and middle region), MFCV for whole regions, that is, the distribution of MFCV has not been studied for various muscle length. The MFCV for the some region in the some muscle length could not be estimated. In the study, the distribution of MFCV in various muscle length for the contraction of 30% MVC was obtained, and the model with the function including muscle length for the estimation of MFCV was presented., Japan Society of Physiological Anthropology, 1997, Applied human science : journal of physiological anthropology, 16, 1, 1-7, English, 1341-3473, 110002508667, AA11053183, 9088091 - 個人閾値を考慮した四基本味の相対濃度に対する誘発脳波

ITAKURA Naoaki; KINBARA Yoh; FUWA Teruhiko; SAKAMOTO Kazuyoshi
We tried to discriminate different forearm's motions by surface EMG signals using neural network. In order to get a higher discrimination rate, the positions of electrodes were improved. We also tried to discriminate similar motions in order to clarify the limitation of the discrimination by surface EMG signals. Two experiments were carried out. One was to discriminate five different motions: grasp, wrist flexion, wrist extension, forearm pronation, and forearm supination (Experiment 1). The other was to discriminate four similar motions which have different quantitative definitions at grasp, wrist flexion/extension, or forearm pronatio/supination (Experiment 2). Four surface electrodes were placed on the skin above the main active muscles: short radial extensor m. of wrist, supinator m., long radial extensor m. of wrist, and ulnar flexor m. of wrist, considering anatomical functions of the forearm's muscles. EMG signals were recorded during 2 sec while the subjects kept the motions. Recorded EMG signals were sampled at 200 msec intervals after full-wave rectifying and low-pass filtering. Therefore, the number of sampling data patterns of EMG signals was 10 for every motion. Three layers of neural network was used for discrimination. The number of units in the input layer is 4, and the number of units in the output layer is 5 or 4. In order to get the best discrimination rate of the motions, we changed the number of units in the hidden layer from 3 to 12. The neural network was trained by the back-propagation algorithm. In Experiment 1, the best average values of discrimination rates under three pattems of EMG signals for each subject were 96.0%, 98.0%, and 87.2% when the numbers of units in the hidden layer were 10, 11, and 3 respectively. In Experiment 2 using original EMG patterns, the best average values of discrimination rates at grasp, extension/flexion, and pronation/supination were 59.5%, 76.0%, and 25.0% respectively. By using normalized EMG patterns, these were 40.0%, 84.8%, and 55.5% respectively., Japan Society of Physiological Anthropology, 1996, Journal of PHYSIOLOGICAL ANTHROPOLOGY and Applied Human Science, 15, 6, 287-294, English, 1341-3473, 10002424813, AA11053183, 9008983 - Distribution of muscle fiber conduction velocity of m. biceps brachii during voluntary isometric contraction with use of surface array electrodes.

The visual recognition (i.e., Iegibility) of moving object was studied. The numerical letters were mainly used as the objects. The influences of (1) directlon of the movement, (2) thickness of line of letter (i.e., stroke width) ,and (3) design of letter to the visual recognition were measured. From these measurements, the optimal numerical letters were proposed in the first step of the study, which were called as llvIAL(initial most optimal arabic letters). The visual recognition of both moving letters IMAL and letters JIS ( Japan industrial standard) employed for motionless state was compared for both the moving and the motionless states. In the presentation for motionless state, Ietters JIS showed iower error rate, but the statistical significance was not proved, while in the presentation for horizontally moving state letters IMAL showed better visual recognition than letters JIS with the significant level of 5 %. Therefore, the useful numerical letters for moving state could be designed in the study. Moreover, the visual recognition of letters IMAL was evaluated for various moving velocities.

In this study, subjects were 35 coordinated dysfunction patients and 30 healthy adults (control), Coordinated function for the patients (standard neurological examination, equilibrium function, and activity of daily living) were measured. Subjects sat on chairs and laid forearm on an elbow rest. Physiological (pathological) tremor at the index finger was measured by a miniature accelerator. These data for each one minute were calculated by Fourier transform and evaluated with peak frequency of power spectrum and integrated amplitude of band in the range from 3 to 100 Hz. The evaluations of the peak frequency and amplitude and coordinated functions were all studied by statistical analysis in order to find corelations among data. In the results, the peak frequency for the patients was lower than that of the control and the amplitude for patients was higher than that for the control. Differences in peak frequency and amplitude between cerebellar-ponte lesions of patients and controls were significant at a level of 1%. Therefore, the influence of the neuro-muscular functions would seem to be related to the mechanism of pathological tremor, so that the theory of spinal reflex by Lippold could not elucidate the mechanism of pathological tremor. More data about mechanism of the coordination and considering functional disorder are much important to give some evaluation and treatment in patient with coordinated dysfunction., Japanese Physical Therapy Association (JPTA), 1989, The Journal of Japanese Physical Therapy Association, 16, 5, 331-338, Japanese, 0289-3770, 110003995094, AN10146032 - Evaluation of muscular load of m. biceps brachii in isometric contraction with the use of microvibration

The purpose of this study was to elucidate the muscular influence of microvibration (MV) and to apply MV to the evaluation of a medical index for dystrophy patients. Subjects were 10 myotonic dystrophy patients (MD; 7 males and 3 females, 43.5±8.2 years), five limb-girdle patients in progressive muscular dystrophy (LG; 4 males and 1 female, 38.6±12.7 years), and 12 normal subjects (males, 21.0±2.0 years) being treated for comparison. Muscular function data for the patients (function stage, grip strength, and pinching force) were measured before the experiment. Metric data (length and girth of upper limb) were also measured. Subjects sat on chairs and laid their right forearm on an elbow rest. MV's at eyelid, m. biceps brachii, and right thenar were detected by MT-3 T. Physiological tremor at the palm was measured by a miniature accelerator. The order used in the experiment was resting state for two minutes, maximum voluntary contraction (MVC), the holding of 60% MVC for one minute, and resting state for three minutes. The MV and physiological tremor data for each one minute were analyzed by (a) integrated amplitude of five bands in the range from 2 to 30Hz, and (b) the first peak frequency of power spectrum. The evaluations of the amplitude and peak frequency and the data of the muscular functions and metrics were all studied by principal component analysis in order to find correlations among the data. MV for eyelid, m. biceps brachii, and thenar showed the characteristic main bands, i. e., delta band (2-4Hz), alpha band (8-13Hz), and theta band (4-8Hz), respectively. MV amplitude for the patients was lower than that, for normal subjects. MV amplitude for the normal subjects increased during 60% MVC, but this phenomenon was not recognized in the patients. Similar results were shown in the first peak frequency: The peak frequency for the patients waslower by 2 Hz than that for the normal controls and was hardly influenced by conditions like rest or load. Differences in peak frequency and amplitude between MD patients and normal controls were at a level of 1% significance. The results of principal component analysis denoted that the function stage closely correlated to the peak frequency of MV at thenar and m. biceps brachii and to the metrics of the upper limb. The above results showed that MV was affected by muscles. Therefore, the influence of the neuromuscular system (i. e., gamma motor system) would seem to be related to the mechanism of MV. Moreover, as the medical index of MV, peak frequency and amplitude for MD and LG were lower than that for the normal subjects. This tendency was emphasized by imposing increased load., Society of Biomechanisms, 1984, Biomechanisms, 7, 21-31, Japanese, 110004695392 - 長時間拘束直立姿勢保持における下肢筋の機能評価

静的持続筋収縮による筋機能低下の評価指標を求めるために, 成人男子10名を用いて45分間の直立姿勢保持を行った. 直立中は自覚症状と下肢筋群 (大腿直筋, 大腿二頭筋, 前脛骨筋, ヒラメ筋) の表面筋電図を調べ, 直立前後においては脛骨神経の電気刺激による腓腹筋の誘発筋電図 (M波, H波) と, 足底の底屈による張力を測定した. 直立中は筋電図の徐波化は認められなかったが, (a) ヒラメ筋の積分筋電図において顕著な増大が認められ, 自覚症状の訴え頻度と呼応していた, 直立後は (b) 最大上刺激電圧における張力 (T) とM波の振幅 (M) との比T/Mが減少し, 筋機能の変化を示し, また (c) H波の最大値 (H) とM波の最大上刺激電圧における値との比H/Mも減少し, 脊髄レベルまで含めた神経・筋の変化を示していた. 比 (T/MやH/M) と自覚症状の訴えや積分筋電図との対応が必ずしも認められなかったことから, 45分間の直立姿勢保持では自覚症状の訴えや積分筋電図の増大は直立姿勢保持により発生したものであるが, 筋電図が徐波化していないため筋機能低下までは表現していない. したがって, 電気刺激により筋機能を100%発揮させて得られた指標T/MとH/Mが, 筋機能低下を示す有効な指標と結論づけられた., Japan Ergonomics Society, 1984, 日本人間工学会誌, 20, 4, 213-223, Japanese, 0549-4974, 40003081415 - Microvibration in myogenic dystrophy patients
