■ Paper- BACKGROUND: The role of activities of daily living (ADL) as a predictor of adverse outcomes in patients with pneumonia is unclear. This study aimed to assess the association between ADL, including physical and cognitive function, and death or readmission in older inpatients with pneumonia. METHODS: This retrospective, single-center, observational study included consecutive older inpatients with pneumonia between October 2018 and December 2019. ADL was assessed using the Functional Independence Measure (FIM). Functional decline during hospitalization was defined as a decrease of at least 1 point in FIM at discharge from admission. The primary outcome was the time to composite 180-day mortality and readmission from any cause after discharge. RESULTS: In total, 363 patients (median [interquartile range] age: 80 [73-86] years, male: 68%) were divided according to the median FIM scores (≥ 100, n = 183 and < 100, n = 180). Among the patients, 25 experienced functional decline during hospitalization, 69 were readmitted, and 17 died. In the Kaplan-Meier analysis, both the lower FIM group and the functional decline group had significantly lower event-free rates than the higher FIM groups and the non-functional decline groups (log-rank test, p < 0.001), respectively. After multivariate analysis, both the lower FIM (adjusted HR, 2.11; 95% CI, 1.24-3.58; p = 0.006) and functional decline (adjusted HR, 3.18; 95% CI, 1.44-7.05; p = 0.005) were significantly associated with the primary outcome. CONCLUSIONS: In older patients hospitalized with pneumonia, ADL limitations at discharge and a decline in ADL were associated with poor outcomes.Oct. 2024, Respiratory medicine, 107830 - 107830, English, International magazineScientific journal

- BACKGROUND: Maximum phonation time (MPT) is used to assess speech and other oral rehabilitation-related issues. Various factors contribute to MPT decline in older individuals. Although the impact of physical frailty on MPT has been suggested, this has not been conclusively determined. OBJECTIVE: To examine the relationship between MPT and physical frailty in community-dwelling individuals aged ≥60 years who were independently mobile. MPT-associated factors were investigated. METHODS: This cross-sectional study analysed the clinical data of 122 patients (age [interquartile range]: 80.0 [74.0-83.0] years) without dementia who visited a neurology department between 1 February 2021 and 31 January 2023. Investigated factors included age, sex, weight, height, body mass index, smoking history, grip strength, functional independence measure, vital capacity, oral diadochokinesis, MPT and the Japanese Cardiovascular Health Study score. Physical frailty was assessed based on the total score from five items (weight loss, weakness, exhaustion, slowness and low physical activity). The relationship between MPT and physical frailty was examined using Spearman's rank correlation coefficient and hierarchical multiple regression analysis. RESULTS: The MPT was negatively correlated with age (r = -0.347, p < .01) and physical frailty (r = -0.681, p < .01) and positively correlated with vital capacity (r = 0.474, p < .01) and height (r = 0.248, p < .01). The hierarchical multiple regression analysis, conducted with MPT as the dependent variable, demonstrated that physical frailty (β = -.59, 95% confidence interval: -0.74 to 0.43, p < .001) had a strong influence on MPT. CONCLUSION: In older individuals, MPT is associated with physical frailty. When assessing MPT in clinical settings, it is advisable to perform a concurrent assessment of physical frailty.Apr. 2024, Journal of oral rehabilitation, 51(7) (7), 1221 - 1228, English, International magazineScientific journal
- INTRODUCTION: The incidence of aspiration pneumonia and the number of medicines prescribed increase with older age. Many medicines pose a risk for aspiration pneumonia, especially those that decrease swallowing function. Older adults with polypharmacy often receive a combination of these medicines. This study aimed to clarify whether polypharmacy is a risk factor for aspiration pneumonia. METHODS: Older adults aged ≥ 65 years receiving oral medicines were included in this case-control study. Patients hospitalized for pneumonia served as the case group, and other age-matched hospitalized patients served as the control group. Patient data were collected retrospectively, and logistic regression analysis was performed using items that showed significant differences in the univariate analysis as explanatory variables. RESULTS: Logistic regression analysis revealed that the number of medicines was not a risk factor for aspiration pneumonia; however, it was associated with the Functional Oral Intake Scale score, male sex, body mass index, and number of comorbidities. CONCLUSION: Although polypharmacy is often defined only by the number of medicines, it is not a risk factor for aspiration pneumonia. A detailed comparison of prescription medicines between the pneumonia and non-pneumonia groups is necessary.Feb. 2024, Archives of gerontology and geriatrics, 122, 105363 - 105363, English, International magazineScientific journal

- The prevention of pneumonia in bedridden older patients is important, and its recurrence in these patients is a relevant issue. Patients who are bedridden and inactive, and have dysphagia are considered to be at risk for pneumonia. Efforts to reduce the bedridden state and low activity may be necessary to reduce the risk of developing pneumonia in bedridden older patients. This study aimed to clarify the effects of postural change from the supine position to the reclining position on metabolic and ventilatory parameters and on safety in bedridden older patients. Using a breath gas analyzer and other tools, we assessed the following 3 positions: lying on the back (supine), resting in the Fowler position (Fowler), and resting in an 80° recline wheelchair (80°). Measurements were oxygen uptake, carbon dioxide output, gas exchange ratio, tidal volume (VT), minute volume, respiratory rate, inspiratory time, expiratory time, total respiratory time, mean inspiratory flow, metabolic equivalents, end-expiratory oxygen, and end-expiratory carbon dioxide as well as various vital signs. The study analysis included 19 bedridden participants. The change in oxygen uptake driven by changing the posture from the supine position to the Fowler position was as small as 10.8 mL/minute. VT significantly increased from the supine position (398.4 ± 111.2 mL) to the Fowler position (426.9 ± 106.8 mL) (P = .037) and then showed a decreasing trend in the 80° position (416.8 ± 92.5 mL). For bedridden older patients, sitting in a wheelchair is a very low-impact physical activity, similar to that in normal people. The VT of bedridden older patients was maximal in the Fowler position, and the ventilatory volume did not increase with an increasing reclining angle, unlike that in normal people. These findings suggest that appropriate reclining postures in clinical situations can promote an increase in the ventilatory rate in bedridden older patients.Mar. 2023, Medicine, 102(10) (10), e33250, English, International magazineScientific journal
- 看護学生が行うオンライングループワーク(OGW)で、カメラ機能をONにした場合とOFFにした場合でのグループワークの取り組み方の違いについて検討した。2021年度のA大学看護学部3年生87名のうち、研究に同意が得られた16名を対象とした。研究期間は2022年3月8日から3月11日であった。4名からなるグループを四つ設定し、無作為にカメラON/OFFをそれぞれ2グループずつ割り付けた。議論時間は最大30分とした。分析の結果、カメラON/OFFでグループ内で発言や意見交換が行われる時間に差異はなかった。カメラOFFの方がカメラONに比べ司会者の発言時間がやや少なく、非司会者の発言時間がやや多かった。OGWに対する感想はほぼ同じようなものであったが、カメラOFFのほうが気が散ることが多く、カメラONには通信途絶が認められた。カメラONの場合は通信途絶のリスクが高まる可能性があるため、公平な学習機会の提供への配慮が必要と考えられた。大阪医科薬科大学看護学部, Mar. 2023, 大阪医科薬科大学看護研究雑誌, 13, 96 - 104, Japanese

- BACKGROUND: Breathing frequency is rarely measured during a field walking test since the current monitoring system using a face mask is cumbersome for older adults. For effective clinical application, we aimed to validate the new respiratory monitor using wearable strain sensors during a 6-min walk test (6MWT) in young adults and patients with chronic obstructive pulmonary disease (COPD). METHODS: The study included young adults and patients with stable COPD voluntarily recruited from three hospitals. Breathing frequency during 6MWT were measured by the strain sensor and a nasal capnometer. Total breathing frequencies were measured by the capnometer. The Bland-Altman method was used to estimate the mean limit of agreement for breathing frequency. RESULTS: A total of 23 young adults (age = 23.1 ± 3.7, mean ± SD) and 50 patients with COPD (age = 75.2 ± 7.2, %FEV1 = 59.1 ± 19.7) were analyzed. During the entire test period, the total breathing frequencies were measured based on an average of 252 ± 46 breaths, and the total breathing frequency was higher in patients with COPD than in young adults (mean difference = -3.349, p < 0.0013). The mean difference in breathing frequency between the strain sensors and capnometer was -0.28 (95%CI: 0.75 to 0.20), and the limit of agreement ranged from -4.1 to 3.6. The CI of the limit of agreement included the limit of equivalence (4 counts/min). CONCLUSIONS: The novel respiratory monitor with wearable sensors achieved the target accuracy in both young adults and patients with COPD in the 6MWT.Nov. 2021, Respiratory medicine, 190, 106675 - 106675, English, International magazineScientific journal
- AIM: This study aimed to assess the association between physical frailty and clinical outcomes among older patients hospitalized for pneumonia. METHODS: This study examined 852 consecutive patients hospitalized for pneumonia between October 2018 and September 2020. Patients who were <65 years old, scheduled for admission, did not receive inpatient rehabilitation, or died during admission were excluded. A short physical performance battery (SPPB) test was performed by physical therapists upon discharge. The primary outcome measure was a composite endpoint of readmission or mortality due to any cause within 6 months of discharge. RESULTS: In total, 521 patients (median age, 80 years; interquartile range, 74-86 years) were included in the analyses, and were divided into the following two groups: robust group with SPPB scores >9 (n = 150), and physical frailty group with SPPB scores ≤9 (n = 371). Of these, 346 (66.4%) patients were men; and the median SPPB score was 6 (interquartile range, 1-10). During the median follow-up period of 53 days (interquartile range, 4-180 days), 92 (17.6%) patients were readmitted and 25 (4.8%) patients died. Patients with physical frailty were at an increased risk for the primary endpoint (hazard ratio, 2.21; 95% confidence interval, 1.44-3.41; P < 0.001); the risk remained significant after adjusting for multiple variables (adjusted hazard ratio, 1.70; 95% confidence interval, 1.05-2.74; P = 0.028). CONCLUSIONS: Among older patients with pneumonia, physical frailty status at discharge was an independent risk factor for readmission and mortality within 6 months after initial discharge.

- OBJECTIVE: To translate the Perceived Maternal Parenting Self-Efficacy (PMP S-E) scale to Japanese and test its psychometric properties among Japanese mothers of low-birth-weight (LBW) infants. DESIGN: Descriptive psychometric study. SETTING: NICUs in two regional perinatal care centers in the Kinki region of Japan. PARTICIPANTS: Seventy-nine Japanese mothers of LBW infants hospitalized in NICUs. METHODS: First, we translated the PMP S-E scale into Japanese and assessed its face and content validity. Second, we assessed the internal consistency, test-retest reliability, and criterion-related and construct validity of the Japanese version of the PMP S-E (JPMP S-E) with data from Japanese mothers of LBW infants. RESULTS: The JPMP S-E mean score was 53.0 (SD = 7.1); the total scores ranged from 38 to 68. The intraclass correlation coefficient of test-retest reliability was .75, and Cronbach's alpha coefficient was .90. With regard to criterion-related validity, we found a significant positive correlation between the JPMP S-E and the Maternal Attachment Inventory Japanese version (r = .45, p < .001), but no correlation existed between the JPMP S-E and the General Self-Efficacy Scale (r = .21, p = .06). We evaluated construct validity using confirmatory factor analysis to assess whether the model fit the previously determined structure of the PMP S-E. The model fit was moderate in the confirmatory factor analysis (comparative fit index = .63, goodness-of-fit index = .63, root mean square error of approximation = .15). CONCLUSION: We found adequate estimates of reliability and moderate indicators of validity for the JPMP S-E, which support the use of the tool for clinical and research purposes.Mar. 2021, Journal of obstetric, gynecologic, and neonatal nursing : JOGNN, 50(2) (2), 214 - 224, English, International magazineScientific journal

- Purpose: Japan has only a few respiratory disease-specific activity of daily living scales that are accepted outside of Japan, and they are not widely used. The Barthel Index dyspnea (BI-d), an improved version of the Barthel Index (BI), may be popular in Japan. The purpose of this study was to develop the Japanese version of BI-d (J-BI-d) and investigate its reliability and validity. Patients and Methods: The J-BI-d was developed using the basic guidelines for scale translation. The study included patients with chronic respiratory disease, receiving outpatient care at two centers between January 2019 and February 2020. Scores on the J-BI-d, modified Medical Research Council scale (mMRC scale), BI, respiratory function tests, and 6-minute walk distance (6MWD) test were measured. To verify the test-retest reliability, the J-BI-d was re-administered, and the intraclass correlation coefficient (ICC) was obtained. Internal consistency was verified by Cronbach's alpha reliability coefficient, and criterion-related validity was verified through a correlation analysis of the J-BI-d with mMRC scale and 6MWD test. Divergent validity was verified through correlation analysis between the J-BI-d and BI. Results: Data for 57 participants (mean age 74.4 ± 8.3 years) were analyzed, and reliability testing was performed with 42 of them. The mean time to retest was 8.1 ± 3.0 days, and the ICC (2, 1) was 0.76 (95% CI: 0.62-0.85), indicating high reliability. Cronbach's alpha reliability coefficient was 0.81, indicating high internal consistency. Correlation coefficients of the J-BI-d with 6MWD test (r = -0.46, p < 0.01) and mMRC scale (ρ = 0.76, p < 0.01) indicated high criterion-related validity. The J-BI-d and BI had a weak negative correlation (r = -0.29, p < 0.05), indicating high divergent validity. Conclusion: The results of this study demonstrate high reliability and appropriate validity of the J-BI-d in patients with chronic respiratory disease.2021, International journal of chronic obstructive pulmonary disease, 16, 1863 - 1871, English, International magazineScientific journal
- BACKGROUND: Dysphagia is a growing health problem in aging societies. An observational cohort study targeting community-dwelling populations revealed that 16% of elderly subjects present with dysphagia. There is a need in elderly communities for systematic dysphagia assessment. OBJECTIVE: This study aimed to verify whether laryngeal elevation in the pharyngeal phase could be measured from the body surface using thin and flexible stretch sensors. METHODS: Thirty-two elderly subjects (17 males, 15 females; mean age ± SD: 89.2 ± 6.2 years) with suspected dysphagia underwent a swallowing contrast examination in which seven stretch sensors were attached to the front of the neck. The elongation of the sensors was measured and compared to the laryngeal elevation time values obtained using videofluorography. The sensor signal detected the laryngeal elevation start time, conclusion of the descent of the larynx, and the laryngeal elevation time. The respective laryngeal elevation times obtained using videofluorography and using the sensor were compared using the Bland-Altman method. RESULTS: The laryngeal elevation time was 1.34 ± 0.46 s with the stretch sensor and 1.49 ± 0.56 s with videofluorography. There was a significant positive correlation between the duration obtained by both methods (r = 0.69, p < 0.0001). A negative additional significant bias of -0.15 s (95% confidence interval -0.30 to -0.03, p = 0.046) was noted in the laryngeal elevation time from the videofluorography measurement. CONCLUSION: Laryngeal elevation time can be measured noninvasively from the neck surface using stretch sensors.Aug. 2020, Journal of oral rehabilitation, 47(12) (12), 1489 - 1495, English, International magazineScientific journal
- Purpose: Children with cerebral palsy may face difficulties using handheld pointing devices, due to involuntary muscle movements. This study aimed at describing the idea of the new wearable sensor switch and assessing its feasibility as an access solution in a case of mixed-type cerebral palsy.Methods: The study participant was a 17-year-old male with mixed-type cerebral palsy characterized by chorea-athetotic movements and bilateral spasticity with gross motor function classification system level V. He exhibited sudden and irregular involuntary upper limb movements when sitting. Because spastic finger movements limited his ability to use a handheld mouse, he used a trackball near his neck as a pointing device (previous input method). The wearable switch system using a stretchable strain sensor was introduced; the sensor was attached to a groove worn on the dorsal regions of the right hand crossing the proximal interphalangeal and metacarpophalangeal joints of the middle finger (new input method). The switch turned on when the subject flexed his middle finger.Results: The user successfully turned the switch on and typed almost the same numbers of characters per trial compared with the previous input method. The speed of his head movements during typing reduced (p < .01), and his sitting posture was nearly upright during computer operation (p < .01). No involuntary movement, requiring physical assistance, was observed when using the wearable switch.Conclusion: The new switch system can be a new option for people with difficulty using standard handheld input devices due to paralysis and involuntary muscle movements.Implications for rehabilitationCerebral palsy is a major cause of motor dysfunction and spasticity and dyskinesia in the fingers and upper limbs may prevent children with cerebral palsy from using handheld input devices.Wearable devices may be useful for children with cerebral palsy who have limited access to handheld pointing devices.We developed a new wearable switch to control devices using a flexible stretchable sensor.The wearable switch contributed to the improvement of sitting posture and reduction of neck burden during the typing task at the speed equivalent to that using the previous method in a child with mixed type of cerebral palsy exhibiting choreoathetotic movements and bilateral spasticity.Jan. 2020, Disability and rehabilitation.

- Respiratory rate, a sensitive indicator of respiratory status, is rarely measured during the field walking test. Our objective was to develop and validate a non-invasive, wearable monitoring system using stretchable strain sensors and an accompanying algorithm capable of providing real-time measurements of respiration during exercise. Twenty-four healthy volunteers wore stretchable sensors during a walking test protocol that included standing, sitting, walking, and walking with a stick. Sensors were placed on the ribcage and abdomen. The Bland-Altman method was used to assess the accuracy and precision of breath counts; total respiration time and inspiration time ratio were determined by custom algorithms and compared with measurements obtained with the standard flow sensor. The output signal from the stretchable sensor was highly synchronized with flow signals. The limits of agreement were within 3 breaths/min throughout the test protocol. Differences between sensors for total respiration time and inspiration time ratio were less than 14% and 26%, respectively. The agreement was maintained regardless of respiratory rate or volume. The wearable respiratory monitoring system yielded accurate and precise breath counts and total duration of respiratory cycle during moderate exercise in healthy young individuals, suggesting that it might be useful in clinical practice.Graphical abstractSPRINGER HEIDELBERG, Dec. 2019, MEDICAL & BIOLOGICAL ENGINEERING & COMPUTING, 57(12) (12), 2741 - 2756, English, International magazine[Refereed]Scientific journal

The Mendelsohn maneuver is one of dysphagia rehabilitation methods and is a swallowing maneuver which voluntarily prolongs laryngeal elevation. In general, the recognition of the laryngeal elevation is difficult for patients. They often need a long-time training to obtain the maneuver. However, showing onset and offset times of laryngeal elevation can promote effective rehabilitation. We propose a measurement device of the laryngeal elevation based on the change of the circumference of the neck. In this study, we develop a neckband-shaped device composed of stretchable strain sensors. The laryngeal elevation changes the neck circumference. The device partially measures the neck circumference. Two methods detect the onset and offset times of the laryngeal elevation. One determines the times from the difference of the time-series circumference of the neck. The other method determines the times from both the difference and a pattern matching. In experiments, 21 healthy subjects conducted 4-second laryngeal elevation in the Mendelsohn maneuver. Simultaneously, a speech-language-hearing therapist determined the times of the laryngeal elevation by palpating the subjects. The method of only the difference correctly detected the onset times. However, the offset times had over 1-second errors in some cases. The other method detected both the onset and offset times with short-time errors. We confirmed that the proposed device and the method with the difference and pattern matching have a potential for a biofeedback rehabilitation device.

- シート状ストレッチセンサを用いた安静仰臥位における嚥下回数の測定<文献概要>本研究はシート状ストレッチセンサを喉頭隆起部の体表面に巻き付けて装着し,喉頭挙上時に波形の変化が認められるか確認し,得られた波形変化から安静仰臥位における嚥下回数を測定できる可能性があるか検討した.被験者は健常成人男性1名,女性1名とし,ストレッチセンサを喉頭隆起部に巻き付け,安静仰臥位で2分の測定時間内に任意のタイミングで唾液を嚥下した.得られた嚥下回数を被験者のセンサの波形,自己申告,検査者の視認の3つの項目から一致率を求めた.結果は,嚥下にともない電圧が嚥下前のベースラインから急速に減少し,再びベースライン付近まで増加する特徴的な波形変化が男女ともに得られた.嚥下回数は3つの項目で一致し,一致率は100%であった.実験の結果は,喉頭隆起部の高さに巻き付けたストレッチセンサの波形が安静状態にある仰臥位時の嚥下回数の測定へ応用できることを示している.(一社)日本言語聴覚士協会, Sep. 2018, 言語聴覚研究, 15(3) (3), 142 - 147, Japanese[Refereed]
- 目的および方法:立位バランス機能と手の巧緻運動における発達的変化並びに、両者間の相関について検討した。3~12歳の幼児と児童を対象とし、立位バランスとしては、課題実施時の動揺値を、手の巧緻運動としては、モンテッソーリの着衣枠課題を用いて着脱に要する所要時間を計測した。結果:立位バランスと座位姿勢時での手の巧緻運動は、どちらも年齢に依存して動揺値や所要時間が減少した。全年齢を通じた解析では、両者間に有意な相関を認めたが、年齢が同一の集団では両者間に有意な相関は認めなかった。結論:立位バランス機能と座位姿勢下での手の巧緻運動の間には、有意な相関を認めなかった。(著者抄録)(公社)日本小児保健協会, May 2018, 小児保健研究, 77(3) (3), 289 - 296, Japanese
- 目的:呼吸リハビリテーションのための簡便で非侵襲的に胸郭運動を計測するストレッチセンサ(STR)が開発された。本研究の目的は、STRによる胸郭運動計測の妥当性を検討することである。方法:健常成人男性12名が立位姿勢で3つのセンサ[STR、インダクタンス式呼吸プレチスモグラフィー(RIP)、スパイロメーター(FLOW)]を装着し、4つの呼吸様式(自然呼吸:120秒、深呼吸:60秒、頻呼吸:60秒、無呼吸:60秒)での胸郭運動を計測した。STRはバンドとして胸部と腹部に装着した。各センサの胸郭運動計測について分析した。結果:STRの出力はFLOWおよびRIPと有意な相関を示した(r=0.50〜1.00、p<0.05)。STRから得た呼吸回数はFLOWから得た実測値と差を認めなかった(p>0.05)。STR出力は呼吸様式によって有意に変化していた(無呼吸<頻呼吸<自然呼吸<深呼吸、p<0.05)。結論:STRは健常若年健常者におけるさまざまな呼吸条件において胸郭運動を計測することができる。(著者抄録)(公社)日本リハビリテーション医学会, 2018, リハビリテーション医学, 55(4) (4), 348 - 357, Japanese[Refereed]Scientific journal
- Associated Factors of Psychological Distress among Japanese NICU Nurses in Supporting Bereaved Families who have Lost Children.PURPOSE: This study aimed (1) to examine the current status of psychological distress experienced by neonatal intensive care unit (NICU) nurses in supporting bereaved families, (2) to identify the factors associated with psychological distress, and (3) to understand the professional characteristics of nurses experiencing high psychological distress by comparing the study results with those of pediatricians. METHODS: We sent questionnaires to 64 NICUs. The psychological distress of nurses was classified into two groups based on the frequency of psychological distress experienced and analyzed using the χ2 test and Fisher's exact test. A multiple logistic regression analysis was used to investigate the factors related to psychological distress. RESULTS: Of the 384 nurse respondents, 190 (49.5%) reported having supported bereaved families, 169 of who were included in the analysis. A total of 123 nurses (72.8%) reported high levels of psychological distress. Our study revealed that the use of coping methods is associated with high psychological distress. The comparison with pediatricians revealed that nurses were significantly more likely to be female and had fewer years of working experience. Nurses were also significantly more likely to use coping methods and to experience high psychological distress. CONCLUSION: Clarifying the coping methods for psychological distress in supporting bereaved families may be necessary, and nurses need to identify appropriate coping methods. In nursing education, information on psychological distress related to children's deaths and bereavement care should be conveyed from the early stage and nurses must obtain preliminary knowledge. The creation of a bereavement follow-up system is recommended.2018, Kobe J. Med. Sci., 64(1) (1), E11-E19, English, Domestic magazine[Refereed]Research institution
- Background Body movements, such as trunk flexion and rotation, are risk factors for low back pain in occupational settings, especially in healthcare workers. Wearable motion capture systems are potentially useful to monitor lower back movement in healthcare workers to help avoid the risk factors. In this study, we propose a novel system using sheet stretch sensors and investigate the system validity for estimating lower back movement. Methods Six volunteers (female: male = 1: 1, mean age: 24.8 +/- 4.0 years, height 166.7 +/- 5.6 cm, weight 56.3 +/- 7.6 kg) participated in test protocols that involved executing seven types of movements. The movements were three uniaxial trunk movements (i.e., trunk flexion-extension, trunk side-bending, and trunk rotation) and four multiaxial trunk movements (i.e., flexion + rotation, flexion + side-bending, side-bending + rotation, and moving around the cranial-caudal axis). Each trial lasted for approximately 30 s. Four stretch sensors were attached to each participant's lower back. The lumbar motion angles were estimated using simple linear regression analysis based on the stretch sensor outputs and compared with those obtained by the optical motion capture system. Results The estimated lumbar motion angles showed a good correlation with the actual angles, with correlation values of r = 0.68 (SD = 0.35), r = 0.60 (SD = 0.19), and r = 0.72 (SD = 0.18) for the flexion-extension, side bending, and rotation movements, respectively (all P < 0.05). The estimation errors in all three directions were less than 3 E. Conclusion The stretch sensors mounted on the back provided reasonable estimates of the lumbar motion angles. The novel motion capture system provided three directional angles without capture space limits. The wearable system possessed great potential to monitor the lower back movement in healthcare workers and helping prevent low back pain.PUBLIC LIBRARY SCIENCE, Oct. 2017, PLOS ONE, 12(10) (10), e0183651, English, International magazine[Refereed]Scientific journal

- The development of upright postural control has often been investigated using time series of center of foot pressure (COP), which is proportional to the ankle joint torque (i.e., the motor output of a single joint). However, the center of body mass acceleration (COMacc), which can reflect joint motions throughout the body as well as multi-joint coordination, is useful for the assessment of the postural control strategy at the whole-body level. The purpose of the present study was to investigate children's postural control during quiet standing by using the COMacc. Ten healthy children and 15 healthy young adults were instructed to stand upright quietly on a force platform with their eyes open or closed. The COMacc as well as the COP in the anterior-posterior direction was obtained from ground reaction force measurement. We found that both the COMacc and COP could clearly distinguish the difference between age groups and visual conditions. We also found that the sway frequency of COMacc in children was higher than that in adults, for which differences in biomechanical and/or neural factors between age groups may be responsible. Our results imply that the COMacc can be an alternative force platform measure for assessing developmental changes in upright postural control.PUBLIC LIBRARY SCIENCE, Oct. 2015, PLOS ONE, 10(10) (10), English[Refereed]Scientific journal
- The balance control mechanism during upright standing has often been investigated using single-or double-link inverted pendulum models, involving the ankle joint only or both the ankle and hip joints, respectively. Several studies, however, have reported that knee joint motion during quiet standing cannot be ignored. This study aimed to investigate the degree to which knee joint motion contributes to the center of mass (COM) kinematics during quiet standing. Eight healthy adults were asked to stand quietly for 30 s on a force platform. Angular displacements and accelerations of the ankle, knee, and hip joints were calculated from kinematic data obtained by a motion capture system. We found that the amplitude of the angular acceleration was smallest in the ankle joint and largest in the hip joint (ankle < knee < hip). These angular accelerations were then substituted into three biomechanical models with or without the knee joint to estimate COM acceleration in the anterior-posterior direction. Although the "without-knee'' models greatly overestimated the COM acceleration, the COM acceleration estimated by the "with-knee'' model was similar to the actual acceleration obtained from force platform measurement. These results indicate substantial effects of knee joint motion on the COM kinematics during quiet standing. We suggest that investigations based on the multi-joint model, including the knee joint, are required to reveal the physiologically plausible balance control mechanism implemented by the central nervous system.

- 嚥下リハビリテーションの1つに喉頭を随意的に持ち上げるメンデルソン手技がある.この手技の問題点として口頭による教示では対象者自身で習得が困難な場合がある.そこで,喉頭運動を視覚的に補助するバイオフィードバックツールの利用が推奨されている.本研究では,バイオフィードバックツールの開発を目的とし,柔軟膜ひずみセンサを用いた喉頭挙上検出方法の検証を行った.若年健常成人(男性9名,女性12名)の頸部に柔軟膜ひずみセンサを組み込んだデバイスを装着し,手技時の喉の周囲径の時系列データを取得した.計測時には言語聴覚士の触診による喉頭挙上判定をセンサと同期して取得した.取得データに対しクラスタリングを行い,手技時の波形を分類した.分類された波形を用いて,1階差分とパターンマッチングにより喉頭挙上の検出を行った.全21試行中12試行で,挙上時間について言語聴覚士の判定との差が1秒未満で検出された.1秒未満であった試行の多くはバスタブ形状の波形であった.若年健常成人において,本手法により喉頭挙上を検出できる可能性が示された.高齢者での波形の分類や,検出アルゴリズムの改善が今後の課題である.公益社団法人 日本生体医工学会, 2019, 日本生体医工学会大会プログラム・抄録集(Web), 58th(Abstract) (Abstract), ROMBUNNO.PO‐M‐071 (WEB ONLY) - S165_2, Japanese
- In this study, we show the measurement of respiratory rate on exercise using a nanoparticle-based humidity sensor. A portable respiratory rate sensor is comprised of a colloidal silica nanoparticle-based humidity sensor chip. The impedance of the silica nanoparticle film is dependent on humidity and it is used for the detection of humid exhaled air. The respiratory rate sensor can be attached on an oxygen mask and the sensor signal is remotely monitored via Bluetooth. We show that the sensor follows a respiratory rate up to 60 bpm. We compare the sensor signal with that of a conventional respiratory measurement unit, which monitors a respiratory volume. The nanoparticle-based sensor can monitor a respiratory rate of an exercising person on a treadmill. The sensor operates stably for almost one year.2019, Proceedings of International conference of the IEEE Engineering in Medicine and Biology Society, 2019, 3567 - 3570, English, International magazine[Refereed]
