Purpose: This study was to evaluate the effect of cranio-cervical flexion based trunk stabilization exercise on gross motor function and posture alignment change in children with spastic cerebral palsy. Design: Randomized Controlled Trial. Methods: Twenty-six children participated in this study. All subjects were randomly assigned to either the Cranio-Cervical Flexion Based Trunk Stabilization Exercise (CCFTS) group (n=13) or the Trunk Stabilization Exercise (TS) group (n=13). In both groups were trained general physical therapy for 10 minutes, in the CCFTS group was trained cranio-cervical flexion based trunk stabilization exercise for 20 minutes and in the TS group was trained trunk stabilization exercise for 20 minutes. The training was provided 2 times a week during 8 weeks. All subjects were measured with the Gross Motor Function Measure (GMFM) and Cranio-Vertebral Angle (CVA) before and after intervention. Results: The results showed that the CCFTS have increased significantly in GMFM (B, C, D and E-dimension) and CVA, and the TS group have increased significantly in GMFM (B, C D and E-dimension). In particular, the CCFTS group improved significantly than TS group in GMFM (B, C and D-dimension) and CVA. Therefore, the cranio-cervical flexion based trunk stabilization exercise improved gross motor function and posture alignment in children with spastic cerebral palsy. Conclusion: These results suggest that cranio-cervical flexion based trunk stabilization exercise is feasible and suitable for individuals with a spastic cerebral palsy and can be used in addition to conventional physical therapy.

Background : There is lack of studies on the effects of the bag-carrying style on the shoulder muscles and body alignment in adults with rounded shoulder posture (RSP). Objective: The purpose of this study was to investigate the effects of various bag-carrying styles on muscle tone, muscle stiffness and spinal alignment in 20 adults with RSP as they were walking on a treadmill. Design : Crossover Study Design. Methods: A subject performed treadmill walking for 15 minutes at a speed of 4 ㎞/ｈ while carrying three different types of bags: a backpack, a cross bag, and a shoulder bag. Results : The results showed that the main effect of timing was observed in the muscle tone for all the variables and in muscle stiffness only for the upper and lower trapezius muscles. As for the main effect of timing, the muscle tone of the upper trapezius and the pectoralis major significantly increased in all conditions, while the muscle tone of the lower trapezius significantly decreased in all conditions. The muscle stiffness of the upper trapezius significantly increased in all conditions, while the muscle stiffness of the lower trapezius significantly decreased in all conditions. As for the spinal alignment, the dimple distance data values significantly decreased for the cross-bag style. Conclusions : This study demonstrated that walking with a heavy bag, regardless of the bag-carrying style, increased muscle stiffness around the shoulders in adults with rounded shoulder posture, and walking with a cross-bag also induced changes in spinal alignment.

We fabricated BiAlO thin film by a solution process with a brush coating to be used as liquid crystal (LC) alignment layer. Solution-processed BiAlO was coated on the glass substrate by brush process. Prepared thin films were annealed at different temperatures of 80℃, 180℃, and 280℃. To verify whether the BiAlO film was formed properly, X-ray photoelectron spectroscopy analysis was performed on Bi and Al. Using a crystal rotation method by polarized optical microscopy, LC alignment state was evaluated. At the annealing temperature of 280℃, the uniform homogenous LC alignment was achieved. To reveal the mechanism of LC alignment by brush coating, field emission scanning electron microscope was used. Through this analysis, spin-coated and brush coated film surface were compared. It was revealed that physical anisotropy was induced by brush coating at a high annealing temperature. Particles were aligned in one direction along which brush coating was made, resulting in a physical anisotropy that affects a uniform LC alignment. Therefore, it was confirmed that brush coating combined with BiAlO thin film annealed at high temperature has a significant potential for LC alignment.

Objective: The purpose of this study was to investigate the effect of thoracic spine and ankle joint alignment on trunk and upper limb muscle activity during trunk forward lean exercise using a sling. Methods: 25 subjects participated in this study. All subjects performed trunk forward lean exercise using a sling under four conditions according to the alignment of the thoracic spine and ankle joints. Trials were performed 3 times in each condition. Muscle activity of the trunk and upper extremity was measured using electromyography. Results: In the dorsiflexion, the thoracic kyphosis condition showed significantly higher muscle activity in the pectoralis major, rectus abdominis, latissimus dorsi, transverse abdominis than dorsiflexion(p<0.05). In the plantar flexion, thoracic kyphosis condition showed significantly higher muscle activity in pectoralis major, transverse abdominis, latissimus dorsi muscle activity than dorsiflexion(p<0.05). Conclusions: Regardless of ankle alignment, thoracic kyphosis condition increased the activity of the pectoralis major, transverse abdominis, latissimus dorsi. Therefore, regardless of the alignment of the ankle, it is recommended to perform the trunk forward lean exercise using a sling in thoracic kyphosis.

The purpose of this study was to analyze the effects of manual therapy on lower extremity alignment in pelvic malalignment. The subjects were 20 adults with pelvic malalignment. They were divided into two groups: manual therapy group (n=10) and stretching exercise group (n=10). Each group performed the intervention two times per week for 4 weeks. The lower extremity alignment was measured by pelvic deviation, functional leg length inequality, and plantar pressure distribution, which were measured between pre- and post-test. In the result of pelvic deviation, there was a significant difference between the pre- and post-test of the manual therapy group and stretching exercise group. In the result of the functional leg length inequality, there was a significant difference between the pre- and post-test of the manual therapy group. In the result of plantar pressure distribution, there was a significant difference between the pre- and post-test of the manual therapy group. These findings suggest manual therapy improves the pelvic deviation, functional leg length inequality, and plantar pressure distribution in the pelvic malalignment.

Objective: Generally, it is known that there is a correlation between excessive calcaneus eversion and a patient with low back pain and it also affects pelvic alignment. However, there are not enough studies that show calcaneal eversion having an effect on the alignment of the trunk. Design: Cross-sectional study. Methods: A 3-dimensional motion analysis system was used to assess the lower limbs, pelvic alignment, and trunk alignment with increased unilateral and bilateral calcaneal eversion in twenty-one subjects. All subjects were asked to maintain a static posture for seven seconds on a wedge three times per posture for measurement and analysis purposes. The wedge used in the process was a lateral wedge with a 10-degree tilt to the lateral direction. To unify all of the subjects' foot position, the front and inner side of the wedge were marked. The height of the tilted wedge's inner side and flat wedge were balanced equally in order to be able to maintain the lateral part of the foot to the same height when producing an increased calcaneal eversion. Results: Comparing the changes in trunk and pelvic alignment in accordance to calcaneal eversion for each posture, there was a significant different in the X and Y-axis for each posture, but not in the Z-axis (p<0.05). Thus, it can be confirmed that calcaneal eversion in the sagittal plane and frontal plane may have and effect on the pelvis and the trunk. Conclusions: Postures with increased bilateral and unilateral calcaneal eversion has an effect on pelvic alignment, but does not cause any changes in trunk alignment.

Purpose: The aim of this study was to investigate the effects of gluteal taping on pelvic alignment, trunk stability, and balance during sitting posture in children with unilateral cerebral palsy (CP). Methods: Thirteen children with unilateral cerebral palsy (six females. seven males; mean age 8.5) participated in this study. All participants were evaluated before and after gluteal taping using an Inclinometer for pelvic lateral inclination, trunk impairment scale (TIS) for trunk stability, and modified functional reaching test for balance during sitting. The collected data were analyzed using a paired t-test. Results: The results of this study were as follows: 1) Statistically significant decreases in the angle of pelvic lateral inclination were observed after gluteal taping in children with unilateral CP (p<.05). 2) Statistically significant increases in TIS score were observed after gluteal taping (p<.05). 3) Statistically significant increases in the range of reaching during sitting were observed after gluteal taping (p<.05). Conclusion: : In conclusion, this study showed that gluteal taping improves pelvic alignment, trunk stability, and balance during sitting in children with unilateral cerebral palsy. Further studies will be required to determine the short- and long-term effects of gluteal taping on improving postural symmetry, trunk stability, and balance.
