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° 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° 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.

PURPOSE: The purpose of this study was to identify the effect of abdominal stabilization exercise with Stabilizer and Gymball. METHODS: The participants were divided randomly into 2 groups each of 20 participants in the gymball exercise group and 20 participants in the exercise group. The changes of respiratory muscle activity between the two groups were measured three times a week for 4 weeks. The activity of rectus abdominis and internal oblique was measured using surface EMG to measure respiratory muscle activity. The training was repeated five sets, and one set was repeated 6 times with one 10 second exercise and 5 second rest. RESULTS: The results of the study showed that there was a significant difference in the amount of respiratory accessory muscle activation, inspiratory pressure, respiratory minute volume at the experimental group with stabilizer and control group with gymball exercise. Between-group difference was statistically significant only for rectus abdominis muscle activation. CONCLUSION: Both the stabilizer and the gymball exercises were effective in improving the respiratory rate but there was no difference between the two groups. Also, when comparing activity of muscle in both group, both groups were effective in improving and more effective than improvement of muscular activity of stabilizer in muscle of stabilizer.

PURPOSE: Most gait assessment tools are expensive and require controlled laboratory environments. Tri-axial accelerometers have been used in gait analysis as an alternative to laboratory assessments. Many smartphones have added an accelerometer, making it possible to assess spatio-temporal gait parameters. This study was conducted to confirm the reliability and validity of a smartphone-based accelerometer at quantifying spatio-temporal gait parameters of stroke patients when attached to the body. METHODS: We measured gait parameters using a smartphone accelerometer and gait parameters through the GAITRite analysis system and the reliability and validity of the smartphone-based accelerometer for quantifying spatio-temporal gait parameters for stroke patients were then evaluated. Thirty stroke patients were asked to walk at self-selected comfortable speeds over a 10 m walkway, during which time gait velocity, cadence and step length were computed from smartphone-based accelerometers and validated with a GAITRite analysis system. RESULTS: Smartphone data was found to have excellent reliability (ICC2,1≥.98) for measuring the tested parameters, with a high correlation being observed between smartphone-based gait parameters and GAITRite analysis system-based gait parameters (r = .99, .97, .41 for gait velocity, cadence, step length, respectively). CONCLUSION: The results suggest that specific opportunities exist for smartphone-based gait assessment as an alternative to conventional gait assessment. Moreover, smartphone-based gait assessment can provide objective information about changes in the spatio-temporal gait parameters of stroke subjects.
