Purpose: The aim of this study was to clarify the gender difference during standing balance in accordance with recruitment of abdominal muscles against sudden support surface translation. Methods: Twenty healthy males (n = 10, $26.50{\pm}3.54$ years, $170.60{\pm}6.30cm$, $72.80{\pm}5.69kg$) and females (n = 10, $24.40{\pm}2.63$ years, $163.00{\pm}4.97cm$, $52.10{\pm}4.41kg$) participated in the study. Each subject performed standing balance task on a platform, which moved in the anterior and posterior direction, with a total of 18 trials in three abdominal conditions (resting, hollowing, and bracing). We analyzed angular displacement of thoracic and lumbar spine and linear displacement of center of mass for evaluatione of spinal stability and standing balance, respectively. Results: Angular displacement of thoracic and lumbar spine and linear displacement of center of mass did not differ significantly between female and male in all conditions. Conclusion: Our results indicate that the ability to maintain spinal stability and standing balance were similar between male and female regardless of the abdominal contractile conditions and the direction of support surface translation.

Purpose: This study was performed to determine the effects of a gluteus maximus strengthening exercise on both spinal alignment and dynamic balance in subjects with kyphosis. Methods: We measured the kyphosis angle of 150 subjects and selected those whose kyphosis angle was > $50^{\circ}$. The participants included 10 male and 12 female college students. After a gluteus maximus strengthening exercise was applied, the subjects were measured by the formetric 4D and Biorescue systems. The collected data were analyzed by a paired t-test with the SPSS (Ver. 21) program for spinal alignment and dynamic balance comparisons both before and after the gluteus maximus strengthening exercise was completed. Results: The results regarding spinal alignment showed statistically significant decreases in pelvic tilt, kyphotic angle, and lordotic angle after the intervention (p < .05). However, trunk imbalance, pelvic torsion, surface rotation, and lateral deviation were not significantly different after the exercise. The results of the dynamic balance showed statistically significant increases in limits of stability after the exercise (p < .05). Conclusion: The above results suggest that the implemented gluteus maximus strengthening exercise may be effective for spinal alignment and dynamic balance in subjects with kyphosis.

Purpose: This study was conducted to develop a Korean version of the trunk control measurement scale (TCMS) and examine the reliability and concurrent validity of the K-TCMS in children with cerebral palsy. Methods: Subjects for the study were 23 children with cerebral palsy (CP)(mean age: 84.70 months) recruited from one CP clinic. For the interrater and test-retest reliabilities, four raters (A, B, C, D) measured the K-TCMS two times using video clips with an interval of two weeks. For the concurrent validity, the Korean version of the gross motor function measure (K-GMFM) was chosen. Inter-rater reliability and test-retest reliability of the three K-TCMS subscale (static sitting balance, dynamic sitting balance and dynamic reaching) scores and the total scores were investigated using the intra-correlation coefficient ($ICC_{3,1}$). Spearman's correlation coefficient (r) was calculated to investigate the concurrent validity. Results: The inter-rater reliability of the K-TCMS subscales and total scores were all high ($ICC_{3,1}=0.968-0.992$). For the test-retest reliability, $ICC_{3,1}=0.827-0.962$. The concurrent validity between the K-TCMS's total and three subscale scores and K-GMFM's total score were r=0.600-0.667. Conclusion: The results suggest that the K-TCMS can be used in clinical and research settings as a standardized tool for CP children. The K-TCMS might be also useful for selecting treatment goals and planning interventions for children with cerebral palsy.

Purpose: The purposes of this study were to develop the Korean version of the trunk impairment scale (K-TIS) and to examine reliability and responsiveness of the K-TIS in patients with stroke. Methods Subjects of the study were 51 stroke patients (mean age: 57.78 years) recruited from two stroke clinics. For the interrater and test-retest reliability, two raters measured the K-TIS two times using video clips with an interval of 2 weeks. For the responsiveness, intensive physical therapy training was provided to all participants 2 times a day for one month or three months depending on the onset of the stroke and the admission rules of the two clinics. Inter-rater reliability and test-retest reliability of the K-TIS three subscales (static sitting balance, dynamic sitting balance, and coordination) scores and total scores were examined using intra-correlation coefficient ($ICC_{3,1}$) and Pearson's correlation coefficient (r). To examine responsiveness, the minimally important difference (MID) was calculated with effect size. Results: Inter-rater reliability of the K-TIS subscales and total scores were all high (ICC3,1=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, $ICC_{3,1}$=0.805-0.901 and r=0.806-0.903, and the MID for acute and post-acute as well as chronic stroke patients remained in the mean change range. Conclusion: It is suggested that the K-TIS might be used for clinical and research purposes as a standardized tool for stroke patients. In addition, it can also be useful in establishment of treatment goal(s) and planning treatment program(s) for patients with stroke.

Objective: The purpose of this study was to evaluate the effect of virtual reality (VR)-based core stabilization exercise on upper extremity function, postural control, and depression among persons with stroke with hemiplegia. Design: Randomized controlled trial. Methods: This study was conducted with the inclusion of 24 participants and were randomly assigned to either the VR-based trunk stability exercise group (n=12) or control group (n=12). The VR-based trunk stability exercise group performed core stabilization exercises in a VR environment for 30 minutes. Meanwhile, the control group conducted general core stabilization exercises for 30 minutes. The participants trained 3 times a week for 4 weeks. The manual functional test (MFT), Box and Block Test (BBT), Berg Balance Scale (BBS), Trunk Impairment Scale (TIS), the Geriatric Depression Scale (GDS) were used to assess all participants before and after the intervention. Results: The VR-based core stabilization exercise group had a significant improvement in upper extremity function (MFT, BBT) and postural control (BBS) compared with the control group (p<0.05). The VR-based core stabilization exercise showed a significant difference after intervention in the TIS and GDS scores (p<0.05), but they did not significantly differ between the two groups. Conclusions: The result showed that VR-based core stabilization exercise can be effective in improving upper extremity function and postural control among patients with stroke more than the sole application of general physical therapy.

The measurement of the radiation energy, trunk temperature, leaf area index (LAI), air temperature, vapor pres-sure, and precipitation has been conducted under a mixed forest at Kwangneung Arboretum during the period of 2001. Characteristics of the diurnal and seasonal variation of the radiative energy were investigated. The aerodynamic roughness length was determined as about 1.6 m and the mean albedo was about 0.1 The downward short-wave radiation was linearly correlated with the net radiation and its correlation coefficient was about 0.96. From this linear relation, the heating coefficient was calculated and its annual mean value was about 0.21 The albedo and heating coefficient was varied with season, surface characteristics, and meteorological conditions. The diurnal and seasonal variations of radiation energy were discussed in terms of the surface characteristics and meteorological conditions. In the daytime, during clear skies, net radiation was dominated by the shortwave radiation. In presence of clouds and fog, the radiation energy was diminished. At night, the net radiation was entirely dominated due to the net longwave radiation. There was no distinct diurnal variation in net radiation flux during the overcast or rainy days. The net radiation was strongest in spring and weakest in winter. The seasonal development in leaf area was also reflected in a strong seasonal pattern of the radiation energy balance. The timing, duration, and maximum leaf area and trunk temperature were found to be an important control on radiation energy budget. The trunk temperature was either equal or warmer than air temperature during most of the growing season because the canopy could absorb a substantial amount of sunlight. After autumn (after the middle of October), the trunk temperature was consistently cooler than air temperature.

Purpose: The transverse abdominis and themultifidus muscle are located in the core. They surround one's trunk and help in body stabilization. Specifically, they control spine articulation to maintain posture and balance. Therefore, weakened deep muscle in the trunk may cause spinal malalignment. This study aims to compare the correlation between the thickness of the transverse abdominis and the multifidus muscle and the spine alignment among college students in their 20s. Methods: This study measured the thickness of the transverse abdominis and the multifidus muscle of 42 healthy college students in their 20s using ultrasonic waves. The thickness of the muscle was measured for the length of the cross-section except for fascia. The thickness of the left and right muscles was measured, and the mean value was calculated. As the thickness of the transverse abdominis can increase because of pressure during exhalation, it was measured at the last moment of exhalation. Spinal alignment was measured by the kyphosis angle, lordosis angle, pelvic tilt, trunk inclination, lateral deviation, trunk imbalance, and surface rotation using Formetric III, which is a three-dimensional imaging equipment. They were measured for three times, and the mean values were calculated. The general characteristics of the subjects were analyzed using descriptive statistics. The correlations between each factor were analyzed using Pearson's correlation analysis. Results: The transverse abdominis showed asignificant correlation with trunk inclination (p<.05). The multifidus muscle showed a significant positive correlation with pelvic tilt and a negative correlation with surface rotation (p<.05). Conclusion: The thickness of transverse abdominis and the multifidus muscle appears to influence spinal alignment. Specifically, the multifidus muscle, which plays an important role on the sagittal plane, influences surface rotation, thus making it an important muscle for scoliosis patients. Therefore, a strengthening training program for the transverse abdominis and the multifidus muscle is necessary according to specific purposes among adults with spinal malalignment.

Background: The aim of this randomized controlled pilot study was to determine the effect of trunk training in wheelchair on fall efficacy, fall risk and activities of daily living in acute stroke patients. Design: Randomized controlled pilot trial. Methods: The study included 18 patients with acute stroke who were randomly allocated to an experimental group (EG) (n=9) and a control group (CG) (n=9). Patients in the EG group received general rehabilitation therapy combined with trunk training in wheelchair for 20min, whereas CG group received general rehabilitation therapy combined with bicycle training for 20min. Both groups performed the exercise 5 times a week for 3 weeks. Outcomes were assessed using Korean-Fall Efficacy Scale (K-FES), Fullerton Advanced Balance Scale (FAB) and Korean-Modified Barthel Index (K-MBI). Results: After 3 weeks of training, both groups showed significantly improved K-FES, FAB and K-MBI (p<.05 in both groups). However, the K-FES, FAB and K-MBI in the experimental group was significantly improving than in the control group (p<.05). Conclusion: These findings indicate that trunk training in wheelchair may be effective at decreasing fall risk and improving activities of daily living in acute stroke patients. Therefore, trunk training in wheelchair may be recommended as an intervention in reducing the incidence of fall risk in acute stroke patient.
