    Purpose: The aim of this study was to clarify the representative values and the proportion below the cut off value related to nutritional status and physical function in maintenance hemodialysis patients.

    Methods: A total of 670 hemodialysis outpatients participated in this cross-sectional study. Patient's background, body mass index (BMI), geriatric nutritional risk index (GNRI), grip strength, knee extension force (KEF), gait velocity, and short physical performance battery (SPPB) were investigated. The validity of the sample size was confirmed, and representative values and the proportions below the cut off values were compared.

    Results: A sufficient sample size was able to be set for patients aged 50-years and older. GNRI, grip strength, KEF, gait velocity, and SPPB decreased with increasing age, and many patients aged 80 years or older were below the cut-off value.

    Conclusion: This study showed the representative values of nutritional status and physical function by age and demonstrated an actual decrease in elderly patients.

    Purpose: We aimed to investigate whether the Mini-Balance Evaluation Test (Mini-BESTest) can be applied to assess walking impairment severity in individuals with spinocerebellar degeneration (SCD) and to compare the difference in walking impairment severity assessed using Mini-BESTest and Berg Balance Scale (BBS).

    Methods: Thirty individuals with SCD participated in the study and were divided into three groups according to the SCD severity classification. They were assessed using Mini-BESTest, BBS, and Functional Independence Measure (FIM). The total scores and distribution of scores from Mini-BESTest and BBS were compared among the three groups. In addition, a receiver-operating characteristic (ROC) plot was used to compare the overall accuracy in assessing walking severity using Mini-BESTest and BBS and to determine appropriate cutoff scores for identifying whether an individual can walk independently.

    Results: The total Mini-BESTest and BBS scores showed significant differences among the three groups. Both scores decreased with an increase in walking impairment severity. Mini-BESTest and BBS had high area under the curve and sensitivity and specificity. A ceiling effect and deviation in bias in the distribution were identified only on BBS.

    Conclusion: Mini-BESTest had a higher accuracy and sensitivity than the BBS was thus considered useful for assessing properties that identify individuals with SCD who can walk independently.

    Purpose: To confirm the relevance of preoperative factors based on post-reverse total shoulder arthroplasty (RTSA) scapula function using scapula-45 radiography.

    Method: Twenty-eight patients were observed for more than 6 months after RTSA. We evaluated how the preoperative physical findings had an influence on their postoperative scapular index, which indicates postoperative scapula function.

    Results: The only significant independent variable that could be extracted for the postoperative scapular index was the preoperative scapular index.

    Conclusion: The only factor affecting the postoperative scapular index is the preoperative scapular index.

    Purpose: To analyze shoulder muscle activity after reverse shoulder arthroplasty (RSA) using electromyography to identify any differences from the muscle activity of healthy shoulders.

    Methods: The subjects included 12 RSA-treated shoulders and 17 healthy (control) shoulders. Shoulder muscle activity was evaluated using surface electromyography at 45° and 90° of shoulder elevation. The subjects held their arms aloft in three directions during recording at flexion, scaption, and abduction. Ratios of integrated electromyographic activity for different muscles at 45° and 90° were calculated and compared between the two groups.

    Results: Muscle activity ratios in the posterior deltoid during flexion, the upper trapezius and posterior deltoid during scaption, and the clavicular pectoralis major during abduction were significantly higher in the RSA group (p<0.05).

    Conclusions: Our results suggest that RSA-treated shoulder muscles behave differently from healthy shoulders during sustained elevation between 45° and 90°.

    Purpose: We investigated the factors significantly associated with postoperative complications after laparotomy for gastric cancer.

    Methods: The study included 24 patients who underwent perioperative rehabilitation before surgery. Patients were categorized into the postoperative complication and the non-postoperative complication groups, and intergroup comparison was performed for statistical analysis. Logistic regression analysis was used to identify factors significantly associated with postoperative complications. The cutoff value was calculated using the receiver operating characteristic (ROC) curve.

    Result: The preoperative 6-min walk distance was significantly lower in the postoperative complication group (257.7 m vs. 353.1 m, p<0.01). Logistic regression analysis showed that the selected factor was only the preoperative 6-min walk distance, and the cutoff value based on the ROC curve was 300 m.

    Conclusion: We observed that the preoperative 6-min walk distance was significantly associated with postoperative complications after laparotomy performed for gastric cancer. Therefore, the preoperative 6-min walk distance might effectively predict complications after laparotomy for gastric cancer. Active prehabilitation and improvement of preoperative exercise tolerance are important in patients showing a 6-min walk distance <300 m.

    Purpose: This study aimed to examine the relationship between N-type test and each developmental domain of the Kinder Infant Development Scale (KIDS).

    Methods: This study included 42 children aged 3-6 years along with their parents. The N-type motor image test for toddlers (N-test) was used to evaluate motor imagery, and scores were calculated for selecting picture cards representing posture (card task) and for change in posture (postural task). Parents answered questions from the KIDS (Type C), and each subscale was scored (etc. physical-motor, receptive language, expressive language, social relationships with children, and social relationships with adults). These scores were then used to examine the relationship between the N-test scores and the development of each domain.

    Results: 32 children completed the N-test. The scores of the N-test and age (in months) showed a significantly positive correlation. The scores for the card task were significantly related to the scores for physical-motor, receptive language, and expressive language from the KIDS. The scores for the postural task were significantly related to the age (in months) as well as scores for physical-motor, receptive language, social relationships with children, and social relationships with adults from the KIDS.

    Conclusion: Our results suggest that the tasks of the N-test are associated with the development of different domains. Postural tasks are related to social development, and it is hypothesized that interpersonal communication experience may be involved in the function of motor imagery.
