The purposes of this study were to investigate biomechanical variables of the lumbar spine for women who enjoy recreational exercises regularly, and to determine the factors that influence these variables. These variables were determined by the X-ray pictures of the lumbar area of 80 housewives who visited the department of rehabilitation at the Y Hospital from October 1997 to March 1998. The sacral inclination angle, the sacrohorizontal angle, the lumbosacral joint angle, and the lumbar lordotic angle were analysed. The t-test, correlation analysis, and multiple regression analysis were used to determine the significant differences and relationships among variables. The result were as follows: 1) There was a significant difference in the sacral inclination angle (p<0.01), the sacrohorizontal angle (p<0.05) and the lumbar lordotic angle (p<0.05) between the bilateral and the unilateral exercise group. 2) With the sacral inclination angle, the sacrohorizontal angle, the lumbosacral joint angle and the lumbar lordotic angle, correlation was found between the sacral inclination angle and the sacrohorizontal angle (p<0.01), the sacral inclination angle and the lumbosacral joint angle (p<0.05), the sacral inclination angle and the lumbar lordotic angle (p<0.05), and the sacrohorizontal angle and the lumbosacral joint angle (p<0.01). 3) In the bilateral exercise group, the sacral inclination angle correlated with age (p<0.01). The sacrohorizontal angle correlated with age (p<0.01) and exercise time (p<0.01). The lumbar lordotic angle correlated with age (p<0.05) and exercise duration (p<0.05). In the unilateral exercise group, the sacral inclination angle correlated with age (p<0.01), while the sacrohorizontal angle correlated with age (p<0.01) and exercise duration (p<0.05). The lumbar lordotic angle correlated with age (p<0.05).

Purpose: This study examined the effect of trunk stabilization exercise upon the lumbar stabilization and foot pressure on an unstable surface with back pain. Methods: The subjects of the study were 10 patients who showed the symptom of back pain with excessive lumbar curve. This study was 4 weeks, 30 minutes per session, three times a week for a total of 12 times as a result of exercise radiation imaging device and foot pressure analyzer. Results: The sacrohorizontal angle was statistically significant(p<0.05). Comparison of the difference between static right and left foot pressure ratio analysis was statistically significant(p<0.05). Dynamic right and left foot pressure comparisons for the difference was statistically significant in the analysis (p<0.05). Conclusion: Trunk stabilization exercise and the reduction of the excessive sacrohorizontal angle, and static and dynamic foot pressure imbalance reduced left and right.

PURPOSE: The purpose of this study was to determine the effect of exercise therapy on low back pain (LBP), the function of paraspinal and abdominis muscles, and the sacrohorizontal angle as seen on the radiographs of the lumbar spine in a young female golf player with LBP. METHODS: This case report describes an 11-year-old female golfer who presented with LBP. The exercise therapy program comprised lumbar joint mobilization, lumbar spine flexion distraction, abdominal bridge, plank, side plank, and single-leg extensions from a 4-point kneeling position for 40 min/day; this was done twice a week for 8-weeks. LBP [visual analog scale (VAS) and Oswestry disability index (ODI)] and function of paraspinal and abdominis muscles [Ito test, curl-up test, $90^{\circ}$ stop test, squat test, opened eye one leg stance test (OEOL), and closed eye one leg stance test (CEOL)] were measured before and after 4 and 8 weeks of exercise therapy. The radiographs were analyzed for the lumbar Cobb's angle and sacrohorizontal angle before and after 8 weeks of exercise therapy. RESULTS: After 4 and/or 8 weeks of exercise therapy, VAS and ODI scores decreased; results for the Ito test, curl-up test, $90^{\circ}$ stop test, squat test, and OEOL and CEOL of muscle function improved; and the lumbar Cobb's angle and sacrohorizontal angle improved. CONCLUSION: These results suggest that exercise therapy improves LBP, muscle function, and radiographic parameters associated with LBP in young golf players. These findings have clinical implications for exercise therapy in young female golf players who have LBP.
