BackgroundLow bone mass is an independent risk factor for osteoporotic fractures. We examined the association between physical performance and bone mass using quantitative ultrasound in community-dwelling postmenopausal Japanese women.
MethodsWe conducted a cross-sectional study on 524 community-dwelling postmenopausal Japanese women who were not being administered osteoporosis medications. Physical performance was assessed on the basis of grip strength, chair stand time, and functional reach. The stiffness index was measured as a quantitative ultrasound parameter for heel bone mass.
ResultsPhysical performance, assessed by grip strength, chair stand time, and functional reach, and the stiffness index significantly decreased with age (both p Conclusions
Physical performance was significantly associated with heel bone mass in community-dwelling postmenopausal Japanese women.

Suppressing the expression of negative emotions caused by injuries prevents athletes from fully accepting their sports injuries. However, acceptance is maintained and promoted when positive reappraisal and suppression are synchronized. This study analyzes individual-differences affecting the use of these two emotion regulation behaviors. A questionnaire consisting of personal variables regarding athletic identity, commitment to sports ethics and emotion regulation behavior scale for suppression and positive reappraisal was conducted on athletes with previous injuries (N = 180). A model estimate using correlation analysis and multiple regression analysis was examined utilizing structural equation modeling. The results indicated that commitment to sports ethics and athletic identity promoted the suppression of expressiveness toward negative emotions and positive reappraisal. In contrast, difficulty describing feelings facilitated suppression and hindered positive reappraisal. These results seem to suggest that commitment to sports ethics and athletic identity might facilitate suppression and positive reappraisal, as well as function as variables maintaining and promoting accepting sports injuries. On the other hand, difficulties in describing feelings might lead to abnormal responses caused by accumulated negative emotions due to the suppression of expressing negative emotions and lack of positive reappraisal promotion.Haemophilic arthropathy, a serious complication of haemophilia, results from recurrent joint bleeding, causing progressive joint damage and severely impacting patient quality of life. Rehabilitation therapy (RT) effectively addresses declining physical function due to joint degradation, but pain during RT can hinder its success. Therefore, an effective pain-alleviating treatment method is required. The single-joint hybrid assistive limb (HAL-SJ), a powered exoskeleton, measures bioelectric potential during muscle contraction and provides motorised support, potentially alleviating pain.
This study outlines our protocol for a randomised, prospective, single-blind (evaluator) trial aimed to investigate the effects of HAL-SJ on pain reduction during RT, kinesiophobia and other physical functions in patients with haemophilia.
This two-group comparison intervention study will include 24 male patients aged 12–85 years diagnosed with a bleeding disorder necessitating RT for pain and physical function improvement. The primary outcome measures pain changes during the first and second RT session in patients receiving HAL-SJ-assisted RT compared with traditional RT without HAL-SJ. The secondary outcomes include kinesiophobia (Japanese version of the Tampa Scale for Kinesiophobia), standing position gait (zebris FDM-T treadmill), range of motion (manual goniometer) and body surface temperature (infrared thermography camera) during the study period of up to 3 months or until the end of 10 RTs. RT intensity remains below that required to move the affected joint against gravity, given HAL-SJ’s muscular support. The follow-up period extends to 1 month after the last RT. Intergroup study variables are compared by an unpaired t-test or Mann-Whitney test. Intragroup comparisons of secondary outcomes are analysed by a paired t-test or Wilcoxon signed-rank test.
This study was approved by the accreditation committee of Nara Medical University Hospital. The study results will disseminate through publication in a peer-reviewed journal.
