Comparative Study Observational Study
Contribution of catastrophizing to disability and pain intensity after osteoporotic vertebral compression fracture.
Pain catastrophizing is a key variable that contributes to disability not only in chronic pain disorders but also after trauma. However, there is little evidence concerning the effect of catastrophizing on pain intensity and disability after osteoporotic vertebral compression fracture. Therefore, the purpose of this study was to evaluate the contribution of catastrophizing to disability and pain intensity after osteoporotic vertebral compression fracture. ⋯ The present study shows that catastrophizing can contribute to disability only in the acute period after osteoporotic vertebral compression fracture. As the compression fracture heals, however, age is the critical determinant of disability.

Multicenter Study
Influence of living environments and working status on low back pain for survivors of the Great East Japan Earthquake.
The Great East Japan Earthquake and devastating Tsunami caused irreparable damage on the northeastern coast of Japan. This study aimed to examine the influencing factors of "Living environment" and "Working status" on low back pain for the survivors of the earthquake evaluated by a self-report questionnaire. ⋯ Though living environment has little effect, "Decrease in income" and "The same occupation as before the earthquake" have strong influences on low back pain.

In non-Western countries including Japan, activities requiring deep flexion of the hip joint, such as seiza (kneeling with calves tucked under the thighs and buttocks resting on the heels) and using squat toilets are commonly practiced. The purpose of this study was to assess longitudinal changes in traditional health-related quality of life measures and measures of physical functions associated with lifestyle for Japanese patients pre-surgery and after total hip arthroplasty. ⋯ The rate of improvement in QOL requiring deep flexion of the hip joint was much slower than that in QOL related to Western lifestyle. Our study suggests a need for lifestyle modification for THA patients in the other countries where kneeling and squatting are commonly performed.

The Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) was developed to resolve problems associated with the original evaluation of cervical myelopathic patients. The aim of this study was to translate the JOACMEQ into Thai as per international recommendations, and to test its reliability and validity in the Thai context ⋯ The Thai version of the JOACMEQ had satisfactory internal consistency and test-retest reliability: it also had good construct validity. It can therefore be used as a reliable tool for assessing quality of life for cervical myelopathy patients in Thailand.
