This study was to verify the effect of complex training programs on the postural balance and trunk muscle strength of the elderly. We recruited 40 elderly participants aged 60 to 75 years. Subjects were evaluated before, and 12 weeks after. The participants underwent complex training programs, including free exercise, elastic band and unstable plate. Exercise were performed as follows: 10 repeats in 50 minutes (0 to 4 weeks), 13 repeats in 50 minutes (5 to 8 weeks), and 15 repeats in 50 minutes (9 to 12 weeks). The training group underwent complex training, including warm up, thrice a week for twelve weeks. The control group did not perform any complex training. Results indicate that the postural balance and trunk muscle strength in the training group significantly increased. Data generated from this study could be applied to develop a complex training program to efficiently build whole body muscle strength.

Objective : This study verifies the effects of sensory integrative (SI) therapy on vestibular- and proprioceptive sensory (BPS) processing ability of a child with Asperger Syndrome (AS). Method : A boy who is 11 years and 2 months old took the Functional Independence Measure for Children (Wee-FIM), Canadian Occupational Performance Measure (COPM), Short Sensory Profile, Bruininks-Oserestky Test of Motor Proficiency-2 (BOT-2), and Test of Playfulness (ToP) for the baseline. The child participated in 3 evaluation sessions and 8 therapy sessions based on the AB research design. Duration of each session is 50 min and the therapy session is divided into 40 minutes for treatment and 10 minutes for evaluation. Since the vestibular sense and proprioception build up one's ability of postural control, several tests were employed to evaluate the child' postural control as outcome measure; distance from front leg of chair to heel of the child with sitting (C-H distance), angle between trunk and thigh (hip joint angle) with sitting, and the 'prone-extension posture' which is a subtest of Clinical Observation of Motor and Postural Skill (COMPS) to examine postural control embodied with integration of reflex and BPS processing. Result : During the therapy, average data of the C-H distance is decreased from 27.33cm to 11.69cm, average data of the hip joint angle is also decreased from $43.3^{\circ}$ to $20^{\circ}$, and average time for the prone-extension posture is increased from 13.15seconds to 24.84seconds. Conclusion : This result indicates that the ability to postural control in sitting and to maintain the prone-extension posture can be improved by sensory integrative therapy, with enhanced BPS processing.

Purpose: To examine the effects of Tai Chi exercise (TCE) on muscle strength, flexibility of low extremities, postural balance and cognition in patients with Parkinson disease (PD). Method: A nonequivalent control-group pre and post-test design was used. Of the 30 participants 15 were assigned to the experimental group and 15 to the control group. The experimental group participated in 8 weeks of TCE which included one day of exercise with instructor on site and 3 days of self-exercise at home guided by a videotape. Results: The 8 weeks of TCE were found to be significantly effective in enhancing strength of low extremities, flexibility of ankles and shoulders, time of tandem stand with eye closed and level on the K-MMSE (Korean mini mental state examination). Conclusion: These results suggest that TCE has positive effects on physical fitness and cognition in patients with PD. Research over an extended period with the TCE intervention is recommended to identify further effects.

Purpose: In this study, children with cerebral palsy were treated for 8 weeks using horse riding trunk proprioception, stability and posture to investigate the effect of hippotherapy in the field of physical therapy. Methods: A total of 18 subjects were divided into an experimental group treated by horseback riding and a control group. Both groups were evaluated pre- and post-treatment. Trunk proprioception was measured three times in the sitting position with their eyes and ears closed to reach the target position the angle error of the mean was calculated. Trunk stability was measured using a forceplate and the data were used to calculate the postural sway path & postural sway velocity. Posture was evaluated using the Posture Assessment Scale (PAS). Results: After hippotherapy, the experimental group showed a significant improvement in trunk proprioception, stability and posture (p<0.05), but the control group improved in posture only (p<0.05). Trunk proprioception, stability and posture was significantly different between the two groups (p<0.05). Conclusion: Eight weeks of hippotherapy is effective in improving trunk proprioception, stability, and posture. Research using this therapy should be studied further as a possible new therapeutic approach in the field of physical therapy.

A quantitative evaluation of postural balance training using a virtual reality bicycle system was performed. In the experiment, the effectiveness of virtual reality bicycle system on postural balance training was analyzed with four male subjects in their twenties. The parameters measured during cycling were cycling time, average velocity, number of times subject deviated from path, and weight shift. Those parameters were evaluated for the quantification of the extent of control. We also measured the parameters on postural control capability after 5th trial and 10th trial in a balance testing system with a force plate to find out the effectiveness of the training. In the balance test with force plate, it was found out that the weight shift was almost zero and the deviation from the target trace reduced significantly after the training with the virtual cycle. The result showed that the virtual bicycle system was an effective system as a rehabilitation training device.

Purpose: The aim of this study was to determine the effectiveness of pelvic tilt training using an inclinometer on joint position sense and postural alignment in individuals with stroke. Methods: Thirty-one subjects with chronic stroke were divided into two groups: the experimental group (16 subjects) and the control group (15 subjects). Subjects in both groups received neuro-developmental therapy five times per week. In addition, the patients in the experimental group also received pelvic tilt training using an inclinometer for 30 minutes, 3 times a week for 4 weeks. Maximal range of anterior, posterior pelvic tilt and joint position sense were used to evaluate pelvic tilt motion. Image analysis was performed for evaluation of postural alignment on in standing position. Results: Significant difference in Iimprovement of pre- and post-intervention of joint position sense was observed showed significant difference (p<0.05) in all groups. Experimental groups showed sSignificant differences in maximal range of posterior pelvic tilt in on the paretic side were observed in the experimental groups compared to with the control group (p<0.05). Conclusion: These findings suggest that pelvic tilt training using an inclinometer may help to improve range of pelvic tilt and joint position sense of stroke patients.

Repetition of landing with visual control in sports and training is common, yet it remains unknown how landing with visual control affects postural stability and lower limb kinetics. The purpose of this study was to test the hypothesis that landing with visual control will influence on lower limb control for intrinsic dynamic postural stability. Kinematics and kinetics variables were recorded automatically when all participants (n=10, mean age: 22.00±1.63 years, mean heights: 177.27±5.45 cm, mean mass: 73.36±2.80 kg) performed drop landings from 30 cm platform. Visual control showed higher medial-lateral force, peak vertical force, loading rate than visual information condition. This was resulted from more stiff leg and less time to peak vertical force in visual control condition. Leg stiffness may decrease due to increase of perturbation of vertical center of gravity, but landing strategy that decreases impulse force was shifted in visual control condition during drop landing. These mechanism explains why rate of injury increase.

Slipping during various kinds of movement often leads to potentially dangerous incidents of falling. The purpose of this paper was to review some of the research performed in the field including such topics as rating scales for balance, kinematics and kinetics of slipping, adaptation to slippery conditions, postural and balance control, and protective movement during falling. Controlling slipping and fall injuries requires a multifaceted approach. Environmental conditions (state of floor surface, tidiness, lighting, etc), work task (walking, carrying, pushing, lifting, etc), and human behavior (anticipation of hazards, adaptation to risks, risk taking, etc) must be accounted for in the assessment of slip and fall-related risks. Future directions of research must deal with modeling of basic tribophysical, biomechanical, and postural control process involved in slipping and falling.

Objective: Swimming and water-based exercise (WE) programs can provide vigorous physical activity in a fun and a motivating environment. The properties of water, may make it easier for children with cerebral palsy (CP) to move and to participate in an WE program. The aims of this study was to evaluate the effect of WEs on postural control in children with spastic CP. Design: Quasi-experimental design (one group pretest-posttest design). Methods: Twenty preschoolers with spastic CP participated in this study. Prior to the application, sufficient warm-up training was performed to allow the subjects to adapt to the water. Afterwards, three different types of underwater leg exercises for the flexor, extensor, and adductor/abductor of muscles of the lower limb were performed. The WE program lasted during 8 weeks, with one-40 minute sessions per week (8 training session). The usual care was performed during the training session. The Korean-trunk control measurement scale (K-TCMS) and weight distribution variability (difference of both Fz) were measured before and after training session. Results: According to the results, the K-TCMS scores of the three sub-levels, including static sitting, dynamic sitting, and dynamic reaching, was significantly increased after the training session (p<0.05). Also, the weight distribution variability was significantly decreased after 8 weeks (p<0.05). Conclusions: We suggest that WEs may improve the postural control ability in children with spastic CP. Furthermore, we support the need for additional research on the effect of WE on gait or activity of daily living performance with a control group included.
