Purpose: This study sought to identify the effects of coordinative locomotor training (CLT) using elastic bands on the flexibility and body alignment of right-handed baseball players in elementary school. Methods: The subjects were 20 instructed right-handed baseball players in elementary school. They were classified into the experimental group with 10 players (n = 10) to be given coordinative locomotor training using elastic bands and the control group with 10 players (n = 10). Flexibility was measured by the sit and reach exercise. Body alignment was measured using formetric 4D method to measure the trunk imbalance angle (TI), trunk torsion angle (TT), pelvic tilt angle (PTi), pelvic torsion angle (PTo), pelvic rotation angle (PR), kyphotic angle (Ky), and lordotic angle (Lo). Results: There was a significant increase in the flexibility within the experimental group (p < 0.05). after the intervention. There was also a significant increase in the difference between the experimental group and the control group (p < 0.05). There was a significant decrease in PR during body alignment in the experimental group after intervention (p < 0.05). An analysis of the differences between groups showed a significant decrease in the PR of the experimental group compared to the control group (p < 0.05). Conclusion These findings show that coordinative locomotor training using elastic bands would be effective for enhancing the flexibility and pelvic rotation of elementary school right-handed baseball players.

Purpose: This study examined the effects of early stabilization exercise focused on the scapulothoracic joint on the recovery of surgical patients due to rotator cuff tear. Methods: The subjects were 30 patients divided randomly into two groups. Group I consisted of 15 patients who practiced shoulder joint stabilization exercises, including glenohumeral joint movement. Group II consisted of 15 patients who practiced scapulothoracic joint stabilization exercises, excluding glenohumeral joint movement. The duration of stabilization exercise was 30 minutes for one day, five days a week, and five weeks. To measure the dependent variables, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, range of motion (ROM), dynamometer of measured grip were used. Results: The DASH, ROM, and grip power were compared. A significant difference was observed before the intervention in each group (p<0.05), and there was no significant difference between group I and group II (p>.05). Conclusion Both shoulder joint and scapulothoracic joint stabilization exercises were effective after the intervention compared to pre-intervention, but there was no difference between the two groups. Unlike many recent studies on the initiation of stabilization exercises, this study allays the concerns between the advantages of ‘early exercise’ and oppositions of previous studies about ‘early exercise’. Nevertheless, further research regarding these subjects is needed.
