    　View Summary

    Positive associations between occupational participation and quality of life (QoL) are known in various populations, but there are few reports in older adults in Japan. To quantify the association between occupational participation in meaningful occupations and QoL among Japanese community-dwelling older adults. A self-administered questionnaire was sent to 626 older adults. QoL was assessed using the World Health Organization (WHO)-five well-being index, and occupational participation in meaningful occupations was measured with the self-administered occupational performance index. The association between occupational participation and QoL was analyzed. Among 367 participants, significant associations were found between occupational participation in meaningful occupations and QoL. In addition, participants with lower QoL exhibited lower levels of occupational participation in occupational control, occupational balance, and satisfaction of performance domains. There is a positive association between occupational participation and QoL among Japanese older adults. Occupational therapists should prioritize occupational participation to support the well-being of older adults.

    　View Summary

    Self-disclosure is the attitude of communicating one’s experiences and condition to others and is an indicator of mental health and an open personality. Frailty, characterized by reduced physical and psychological resistance, predicts the incidence of dependency and mortality. Although low self-disclosure may be associated with frailty, there is no scale to measure older adults’ self-disclosure. This cross-sectional study assessed the validity of a self-assessment self-disclosure questionnaire and examined the association between the content of self-disclosures to friends and acquaintances and frailty among community-dwelling older adults. A total of 237 adults aged ≥65 in Japan were surveyed using a mailed self-administered questionnaire in 2021. The self-disclosure scale consisted of 10 items and showed adequate validity. Participants were classified into a robust group (n = 117, women 57.3%) and a frailty group (n = 120, women 73.3%) using the Kihon Checklist. After adjusting for covariates, multivariate-adjusted logistic regression models revealed frailty was associated with lower self-disclosure of recent positive events, motivation and strengths (indicating strong points) in life, relationships with family and relatives, experiences of work and social activities, and financial status. The proposed questionnaire must still be further tested in other populations, but our initial results may contribute to preventing frailty and improving mental health among community-dwelling older adults.

    　View Summary

    This study aimed to investigate the characteristics of the postural control in rats with or without lesion of sensorimotor cortex (SMC). For this purpose, we developed a novel posturography technique to measure changes of center of pressure (COP) of small animals including rats during inclination of a floor surface at different angle velocities and in antero-posterior and left-right directions. In some animals, fore- and hind-limb extensor EMGs were measured simultaneously together with COP changes during floor inclination. Rats exhibited dynamic COP changes and phasic EMG activities along with increase of floor inclination. However, rats with lesion of SMC showed different patterns of postural change and uncoordinated EMG activities. This indicated that rats exhibited dynamic postural adjustments in response to postural perturbation and also indicated that this postural adjustment was impaired by lesion of SMC.

    本研究では中枢部分損傷後の歩行機能回復の神経機序解明を目的とし、下部胸髄半切断を施した除脳ウサギ歩行標本を用いて解析を進めた。この結果、脊髄半切断急性期には脊髄健常側後肢のみに歩行運動が誘発されたが、半切約1週間後には両側後肢に誘発されることを見出した。脳幹-脊髄歩行神経機構における歩行駆動信号の伝達経路の同定や末梢感覚フィードバックの機能的役割に関する解析から、脊髄半切断後の歩行機能回復は、時間経過に伴って脳幹下行性系と脊髄神経機構に生じる可塑性変化による可能性が示唆された。
