ABSTRACT
[Purpose] This study investigated the changes in caregiving risk and motor function among older adults participating in community gatherings ("Kayoinoba") in Koshigaya. [Participants and Methods] A total of 257 older participants who engaged in the Kayoinoba program for 6 months from its inception were included in the analysis. Caregiving risk and motor function were assessed twice-once at the beginning of the Kayoinoba (first assessment) and again 6 months later (second assessment). The Kihon Checklist was used to evaluate caregiving risk, and the timed up-and-go, one-leg standing, and 30-s chair-stand tests were done to evaluate motor functioning. Participants were divided into pre-frail and healthy groups, and the first and second assessments were compared. [Results] The Kihon Checklist score of the pre-frail group significantly improved from the first to the second assessment. The pre-frail group had lower composite scores for physical function, outdoor activities, and depression mood items based on the Kihon Checklist; the healthy group showed no such differences. Performance on the 30-s chair-stand test was significantly better in the second assessment than in the first assessment in both groups. [Conclusion] The findings of this study emphasize the benefits of participating in Kayoinoba among high-risk older adults and provide the knowledge for developing a healthier community-based symbiotic society.
ABSTRACT
A-38-year-old man suddenly developed nausea, vomiting and vertigo during chiropractic neck manipulation. This was followed by right hemiplegia, right deep sensory disturbance and left hypoglossal nerve palsy, consistent with the medial medullary infarction (Dejerine syndrome). The MRI revealed infarction at left medial part of the medulla. The vertebral angiogram and MRA showed marked narrowing of the left vertebral artery. X-rays of the cervical spine showed no spondylosis, dislocation nor osteolysis of the odontoid process. The serological studies, including lupus anticoagulant, protein C, and protein S gave normal results. Although vascular accidents involving the brain stem after chiropractic neck manipulation have been reported since Pratt-Thomas and Berger, previous reports are still rare. In them lateral medullary infarction (Wallenberg syndrome) is probably the most common case. On the other hand, medial medullary syndrome (Dejerine syndrome) is absolutely rare. To our knowledge, the only one report has been made by Watanabe and his colleagues before our present case. The mechanism was suggested that rotation and tilting of the neck stretches and compresses the vertebral artery at the cervical joint causing injury to the vessel, with an intimal tearing, dissection, and pseudoaneurysm formation. Consequently, the present case may be caused by injury to the left vertebral artery with an intimal tearing during neck manipulation sufficient to cause disection and subsequent infarction of the brain stem.
