Objective: This study aims to analyze the factors that affect the ability to maintain dynamic sitting balance (DSB), biomechanical characteristics, and physical characteristics in spinal cord injuries (SCI) patients. Background: Virtual ski training systems, ski equipment, and training protocols for disabled skiers are being studied to spread awareness. However, few studies have been reported on the sitting balance ability associated with chair mono skiing. Method: A dynamic sitting balance border system was built to investigate the ability to maintain dynamic sitting balance in SCI patients. Trunk muscle activity was evaluated by electromyogram while conducting dynamic sitting balance tests. The trunk muscle strength was tested with a portable handheld dynamometer. Physical activity scores were measured with the physical activity recall assessment. Results: There were high levels of correlation between the ability to maintain DSB and trunk flexor strength, extensor strength, rotator strength, and physical activity score. However, height, weight, and injury level in SCI patients were not correlated with the ability to maintain DSB. Additionally, strong negative correlations were found between muscle activities of the external oblique and lumbar erector spinae muscles and the ability to perform the backward tilt test. Trunk extensor muscle activity during the ball lifting test was significantly higher than in other tests. Conclusion: The results indicate that improving trunk muscle strength and physical activity can increase the ability to maintain DSB. Application: The findings of a close relationship between trunk strength, physical activity, and the ability to maintain DSB need to be reflected in the chair mono ski training program.

Background: Scapular dyskinesis may cause not only rotator cuff (RC) tear but also weakness of the upper extremity, studies on scapular dyskinesis that may occur after RC repair is still lacking. Objects: To determine whether scapular dsykinesis was present in patients after arthroscopic RC repair and to investigate the influence of passive scapular stabilization on upper extremity strength. Methods: A total of 30 patients after RC repair participated in this study. To compare the scapula of the arthroscopic RC repair shoulder and the contralateral shoulder, the winged scapula (WS) was measured using a scapulometer and scapular dyskinesis was also classified by type. Fixed instruments for muscle strength measurements were used to measure upper extremity muscle strength differences depending on passive scapular stabilization position or natural scapular position. A chi-square test, an independent t-test and a 2-way mixed measures analysis of variance (ANOVA) was used as statistical analysis. In analyses, p < 0.05 was deemed to be statistically significant. Results: Postoperative shoulder had a significant association with scapular dyskinesis and the WS compared to the contralateral shoulder (F = 0.052, p < 0.01). Postoperative shoulder, muscle strength in the shoulder abduction (p < 0.01), elbow flexion (p < 0.01) and forearm supination (p < 0.05) were significantly greater in the scapular stabilization position than in the scapular natural position. Conclusion: Patients underwent arthroscopic RC repair had a significant association with scapular dyskinesis and muscle strength was improved by a passive scapular stabilization position, therefore scapular stabilization is important in rehabilitation program.

Purpose: The purpose of this study was (1) to examine the effects of a Health Promotion Exercise Program (HPEP) on functional improvement, physical strength (PS) and muscle activation (MA), and the interactive influence with activities of daily living (ADL) and instrumental activities of daily living (IDAL) in the elderly, and (2) to develop and provide a HPEP for the elderly in order to prevent declines and impairments in integrated nerve function and physical capacity. Methods: Our study included relatively healthy elderly people aged 65 years or older. The experimental group, which was composed of 30 people, participated in a HPEP 50~60 minutes a day, 3 times a week, for a total of 12 weeks. Results: Confirmatory factor analysis (CFA) validated the measurement models for MA, physical strength, ADL and IADL with a p<0.01. This confirms (i) the beneficial effects of the ADFP on their MA and PS, and (ii) that their improvement in PS, in turn, can improve their IADL. The results of this study indicates that ADFP can help Korean seniors 65 years or older improve their MA, PS, ADL, and IADL, and do so synergistically. Conclusion: An HPEP, when organized in such a way that the elderly can easily do it, and when exercise items and intensity can be programmed and reorganized accordingly to individual physical and physiological characteristics by presenting 5 categorized health domains of physical strength, may be useful, especially because it can be practiced irrespective of time and place.
