ABSTRACT
Study DesignCross-sectional study.PurposeThe purpose of this study was to investigate the effects of psychotic symptoms such as anxiety and fear in patients undergoing lumbar spinal canal stenosis.Overview of LiteratureRecently, patients with spinal disorders have not only been evaluated objectively for their disease, but also for patient-reported outcomes (PROs) including pain, physical function, and quality of life (PROs). Since depression has been previously associated with surgical outcomes, several studies have indicated that psychological problems may worsen the effects of pain and make treatment increasingly difficult.MethodsA questionnaire survey was conducted on 346 lumbar spinal stenosis (LSS) patients who visited our hospital from 2010 to 2016. The content of the questionnaire included questions on PROs (Japanese Orthopedic Association Back Pain Evaluation Questionnaire [JOABPEQ], Roland–Morris Disability Questionnaire, Japanese version [RDQ], and Zurich Claudication Questionnaire [ZCQ]) and psychological evaluation (Self-rating Questionnaire of Depression, Pain Catastrophizing Scale, Pain Anxiety Symptoms Scale-20 [PASS-20], Hospital Anxiety and Depression Scale, and Brief Scale for Psychiatric Problems in Orthopedic Patients). IBM SPSS Statistics (IBM Corp., Armonk, NY, USA) was used for statistical analysis and Spearman’s rank correlation coefficient, Mann-Whitney U-test, and multiple regression analysis were also performed.ResultsNo significant correlations were found between psychological factors and PROs (r>0.4). However, patients with abnormal scores for preoperative psychological items on questionnaires other than the PASS-20 also had lower scores for lumbar spine dysfunction and social life dysfunction on the JOABPEQ subscales along with higher scores for the RDQ, symptom severity and physical function on the ZCQ compared to those with normal psychological scores (pConclusionsPreoperative psychological factors in patients with LSS were associated with their RDQ, JOABEPQ, and ZCQ scores. These results suggest that factors such as catastrophic thoughts on pain, anxiety, depression, and fear that may affect the clinical outcomes in patients with LSS should be evaluated before surgery to facilitate psychological interventions.

ABSTRACT
The purpose of this study is to develop a new system for measuring leg motions using a portable three-dimensional accelerometer. The measuring system is composed of acceleration sensors (Micro Stone, MA3-10Ac), a data logger, a data reader, and a personal computer. The personal computer draws a graph of the acceleration of movements (i.e., accelerogram) from the output signals of the acceleration sensors. We then calculated the average acceleration to evaluate leg motions. We drew the accelerograms from 19 young subjects and 36 elderly subjects during the performance of physical fitness activities and walking. Different accelerograms were obtained from two subjects for different walking styles. The average accelerations at the lumbar, ankle and toe points were higher at all axes during movements from the physical fitness activities in the elderly subjects. The accelerations of leg motion at the knee point were, however, lower in the up and down axis in the elderly subjects than in the young subjects, although they were higher in the back and forth and the right and left axes. The new instrument has enabled us to evaluate leg motions by measuring three-dimensional acceleration during the performance of physical fitness activities and walking. The average accelerations of leg motions showed age-related changes. Thus, the average acceleration of leg motions may be used as a new index for evaluating leg motions at the dynamic state.
