The Pain Catastrophizing Scale (PCS) is a commonly used as measure of pain catastrophizing. The scale comprises 13 items related to magnification, rumination, and helplessness. To facilitate quick screening and to reduce participant's burden, the four-item and six-item short forms of the English version of the PCS were developed. The purpose of the present study was to evaluate the psychometric properties of a Japanese version of the short forms of PCS using a contemporary approach called Rasch analysis. ⋯ Six-item short form of PCS has acceptable psychometric properties and is suitable for use in participants with musculoskeletal pain. Thus, six-item can be used as brief instruments to evaluate pain catastrophizing.

Multicenter Study
A Japanese nationwide multicenter survey on perioperative complications of corrective fusion for elderly patients with adult spinal deformity.
Recently, corrective fusion surgery for patients with adult spinal deformity (ASD) has become common in Japan. This study aimed to clarify the status of surgeries for ASD in Japan, focusing on perioperative complications. A nationwide multicenter survey gathering information on surgically treated ASD patients was conducted by the committee for Adult Spinal Deformity of the Japanese Scoliosis Society. ⋯ Older (aged over 65 years) ASD patients showed greater rates of deformity due to the occurrence of degeneration and vertebral fractures, as well as a higher incidence of peri-and postoperative complications. Efforts to reduce perioperative complications are therefore imperative, especially for elderly ASD patients in our aging society.

Comparative Study
The Japanese version of the STarT Back Tool predicts 6-month clinical outcomes of low back pain.
The STarT Back Tool classifies patients into low-, medium-, or high-risk groups according to risk for chronic low back pain. The Japanese version of the STarT Back Tool (STarT-J) has been translated and psychometrically validated. The present analysis investigated the predictive ability of the STarT-J. ⋯ The STarT-J predicted 6-month pain and disability outcomes. The STarT-J is an easy-to-use tool to screen for patients who are more likely to have chronic low back pain, and may be useful to initiate stratified care in primary care settings.

We collected the radiographic and clinical data of 129 AIS patients (Lenke type 1-6) to analyze the characteristics of cervical sagittal alignment in adolescent idiopathic scoliosis patients and the correlations between cervical sagittal alignment and global sagittal alignment, and clinical symptoms. ⋯ The cervical sagittal alignment in AIS patients was related with thoracic kyphosis and lumbar lordosis, especially with thoracic kyphosis, but not with the coronal angle of thoracic and lumbar spine, and pelvic parameters.
