[Purpose] The purpose of this study was to determine whether strict adjustment of the pillow height using the Set-up for Spinal Sleep method improves clinical outcomes like neck pain and somatic symptoms. [Participants and Methods] A total of 84 participants with chief complaints of stiff shoulders and neck pain were evaluated using the numerical rating scale and the Somatic Symptom Scale-8. Questionnaires were used to collect data at the baseline, after two weeks, and after three months of adjusting the pillow height. [Results] Forty-two participants (50%) achieved the minimal clinically important difference for neck pain with a decrease of three points or higher in the numerical rating scale. The baseline neck pain scores were significantly higher in the group that achieved the minimal clinically important difference. The three-month change in neck pain and the Somatic Symptom Scale-8 was significantly greater in participants who were satisfied with treatment. There was a significant positive association between improvement in the numerical rating scale score and improvement in the Somatic Symptom Scale-8 at three months. [Conclusion] Strict adjustment of the pillow height using the Set-up for the Spinal Sleep method significantly improved both physical neck pain and somatic symptoms related to psychological and social problems.

[Purpose] Humans keep their trunks vertical while walking. This defining characteristic is known as upright bipedalism. Research on the neural control of locomotion indicates that not only subcortical structures, but also the cerebral cortex, especially the supplementary motor area (SMA), is involved in locomotion. A previous study suggested that SMA may contribute to truncal upright posture-control during walking. Trunk Solution® (TS) is a trunk orthosis designed to support the trunk in decreasing the low back load. We hypothesized that the trunk orthosis might reduce the burden of truncal control on the SMA. The objective of this study was, therefore, to determine the effect of trunk orthosis on the SMA during walking. [Participants and Methods] Thirteen healthy participants were enrolled in the study. We measured the hemodynamics of the SMA during walking with functional near-infrared spectroscopy (fNIRS). The participants performed two gait tasks on a treadmill: (A) independent gait (usual gait) and (B) supported gait while wearing the TS. [Results] During (A) independent gait, the hemodynamics of the SMA exhibited no significant changes. During (B) gait with truncal support, the SMA hemodynamics decreased significantly. [Conclusion] TS may reduce the burden of truncal control on the SMA during walking.

To investigate the associations between psychosocial factors and the development of chronic disabling low back pain (LBP) in Japanese workers. A 1 yr prospective cohort of the Japan Epidemiological Research of Occupation-related Back Pain (JOB) study was used. The participants were office workers, nurses, sales/marketing personnel, and manufacturing engineers. Self-administered questionnaires were distributed twice: at baseline and 1 yr after baseline. The outcome of interest was the development of chronic disabling LBP during the 1 yr follow-up period. Incidence was calculated for the participants who experienced disabling LBP during the month prior to baseline. Logistic regression was used to assess risk factors for chronic disabling LBP. Of 5,310 participants responding at baseline (response rate: 86.5%), 3,811 completed the questionnaire at follow-up. Among 171 eligible participants who experienced disabling back pain during the month prior to baseline, 29 (17.0%) developed chronic disabling LBP during the follow-up period. Multivariate logistic regression analysis implied reward to work (not feeling rewarded, OR: 3.62, 95%CI: 1.17–11.19), anxiety (anxious, OR: 2.89, 95%CI: 0.97–8.57), and daily-life satisfaction (not satisfied, ORs: 4.14, 95%CI: 1.18–14.58) were significant. Psychosocial factors are key to the development of chronic disabling LBP in Japanese workers. Psychosocial interventions may reduce the impact of LBP in the workplace.

Background: We designed a quick simple exercise program that can be performed in a short period of time in real-world occupational health settings and investigated the effects of three months of program implementation on non-specific low back pain (NSLBP).Methods: Participants were 136 individuals working in the manufacturing industry. The quick simple exercise program was designed to be doable in three minutes and consisted of two exercises: a hamstring stretch and a lumbar spine rotation with forward, backward, and lateral flexion. This was a randomized controlled trial incorporating an intervention group to whom the exercises were recommended within a leaflet, and a control group to whom the exercises were not recommended. NSLBP was evaluated at baseline and after three months using numerical rating scale (NRS) scores, ranging from 0 points (no pain at all) to 10 points (worst pain imaginable). The percentages of cases that improved by a minimal clinically important difference (two points or above) were compared.Results: Overall, 76.1% of the intervention group participants performed the quick simple exercises at least once every one or two days. Three months after baseline, a significantly higher percentage of participants in the intervention group (17 participants: 25%) had NSLBP improvement of two or more points on the NRS compared to that in the control group (8 participants, 12%) (P = 0.047). The average NRS score decreased significantly from 1.87 ± 1.86 to 1.33 ± 1.60 in the intervention group but showed no significant change in the control group, transitioning from 1.46 ± 1.73 to 1.52 ± 1.83. A significant interaction was also observed between the intervention and control groups (F = 6.550, P = 0.012).Conclusions: Three months of a quick simple exercise program among workers in the manufacturing industry increased the percentage of workers with improvement in the NRS scores. This suggests that the program is effective in managing NSLBP in workers in the manufacturing industry.Trial registration: UMIN-CTR UMIN000024117.

This study examined whether a higher level of psychological detachment during non-work time is associated with better employee mental health (Hypothesis 1), and examined whether psychological detachment has a curvilinear relation (inverted U-shaped pattern) with work engagement (Hypothesis 2). A large cross-sectional Internet survey was conducted among registered monitors of an Internet survey company in Japan. The questionnaire included scales for psychological detachment, employee mental health, and work engagement as well as for job characteristics and demographic variables as potential confounders. The hypothesized model was tested with moderated structural equation modeling techniques among 2,234 respondents working in the tertiary industries with regular employment. Results showed that psychological detachment had curvilinear relations with mental health as well as with work engagement. Mental health improved when psychological detachment increased from a low to higher levels but did not benefit any further from extremely high levels of psychological detachment. Work engagement showed the highest level at an intermediate level of detachment (inverted U-shaped pattern). Although high psychological detachment may enhance employee mental health, moderate levels of psychological detachment are most beneficial for his or her work engagement.

[Purpose] This study evaluated whether obesity is a risk factor for low back pain, by using body fat percentage (%FAT) and body mass index (BMI) as indices of obesity among Japanese males. [Subjects and Methods] This study included 1,152 males (average age: 28.0 ± 4.6 years). BMI was calculated from subject’s height and weight, and %FAT was estimated by the thickness of two parts of skin. Low back pain, drinking and smoking were surveyed using a self-administered questionnaire, and maximal oxygen uptake was measured by a submaximal exercise test using a cycle ergometer. [Results] A significant positive dose-response relationship was shown between %FAT and persistent low back pain prevalence. Similarly, a significant positive dose-response relationship was confirmed between BMI and persistent low back pain. [Conclusion] This study suggests that both high %FAT and BMI are risk factors for persistent low back pain.
