Purpose : This study examined the effects of balance training using virtual reality program on sitting balance ability and activities of daily living (ADL) in stroke patients. Method : In the study, 20 patients with hemiplegia were divided into two groups: experiment group (EG) of 10 patients and control group(CG) of 10 patients. The two groups received general occupational therapy for 30 minutes, per day, at a rate of 5 times per week for 6 weeks. The EG was additionally conducted which was performed virtual reality balance training and the CG was conducted general occupational therapy balance training for 30-minutes, once a day, 3 times a week for 6 weeks. Result : The evaluations of this study included: limit of stability(LOS), modified Functional Reach Test(mFRT), and modified Barthel Index(MBI). The patients were evaluated before and after their six week training programs. Significant differences in the LOS, mFRT, MBI were found between pretest and posttest scores in both the EG and CG groups(p<.05). Also, LOS, mFRT, MBI were significant different between the groups at post-test(p<.05). Conclusion : The study findings suggest that virtual reality balance training can improve sitting balance and ADL ability in stroke patients.

The Pediatric Balance Scale (PBS) was balance measurement equipment for school-age children with mild to moderate motor impairments. The aims of this study are to examine the correlation between PBS and spatiotemporal gait parameter and to identify the walking function with cerebral palsy through balance scale. The PBS consists of 14 items such as sitting of standing, standing to sitting, transfers, standing unsupported, standing on one foot, turning 360 degrees, turing to look behind, etc., and the spatiotemporal parameters include walking speed, stride length, step length, step width, cadence, double-limb support. All subjects were independently ambulatory children with spastic diplegic cerebral palsy, and they were assessed on PBS and spatiotemporal gait parameters by an experienced pediatric physical therapist. Pearson's correlation coefficient was used to assess the correlation between PBS and spatiotemporal gait parameters, and the level of significance was set at ${\alpha}$ = 0.05. Total score of PBS(r=.49~.58), standing to sitting(r=.48~.60), turning to look behind(r=.47~.53), and pick up object(r=.52~.69) were positively correlated with walking speed, stride length, step length, and cadence. Most items of the PBS were negatively correlated with double-limb support(r=-.48~-.92). These findings suggest that the pediatric balance scale can be applied to estimate gait function level for children with spastic diplegic cerebral palsy.

This study examined the effects of combined exercise training for preventing falls on the physical performance, falling index, and balance in elderly women. All subjects (N = 32) were recruited and divided randomly to either a combined exercise group (n= 16, EX) or non-exercise control group (n = 16, CON). During 12 weeks of training, the subjects in the EX performed the combined exercise programs (three times/week, 60min/session), and the subjects in the CON maintained their ordinary lives. At the PRE, MID, POST tests, All subjects completed senior fitness tests(dynamic balance, two minutes walking, sit and stand for 30 seconds), tests for falling risk with Tetrax, and tests for posture balance with the spine balance 3D. After the baseline tests, two-way repeated-measures ANOVA with contrast testing was used with SPSS 21.0. Alpha was set to 0.05. In the results, the dynamin balance (p=.001), two minutes walking (p=.001), sit and stand for 30 seconds (p=.001), falling risk (p=.002), and posture balance (p=.034) in the EX were significantly different, but not in the CON. Thus, elderly females who performed combined exercise training for 12 weeks can increase their physical fitness & posture stability and reduce their falling risk.

본 증례연구는 복합손상을 가진 척수손상환자의 재활치료과정을 소개하여 유사한 사례의 치료에 도움이 되고자 하는 것이다. 증례연구의 대상자인 26세의 남자환자는 흉수 4번 완전손상과 사고 당시 전기화상에 의한 좌측하박 절단과 우측손의 정중신경이 마비되었다. 치료초기에는 일상생활동작 검사에서 MBI (Modified Barthel Index) 점수가 22점으로 독립적으로 가능한 것은 거의 없었고, 기능적으로도 모든 도움이 필요한 상태였으나 재활치료결과 독립적으로 가능한 기능수행 능력은 돌아눕기, 일어나 앉기, 침상에서 의자차로 이동하기, 의자차 굴리기였고 제한적이기는 하지만 독립적으로 가능한 일상생활동작은 식사, 상의 입기, 의자차와 같은 높이의 이동 등이 가능하여 MBI 점수가 47점을 나타내었다. 이 환자의 초기의 장기치료목표는 전동 의자차를 이용하여 보호자의 도움을 줄이는 것이었다. 그러나 환자가 익숙하게 의지를 사용하였으며 일반 의자차 사용을 위해 필요한 만큼의 근력증가가 있었고, 의자차에 앉은 상태의 균형감각이 증가하여 목표를 수정하여 일반 의자차를 사용하도록 하였다. 환자 본인이 가지고 있는 재활 잠재력을 최대로 이끌어낼 수 있도록 유도한 결과 부분적으로 제한이 있었지만 실내에서는 의자차를 이용하여 독립적인 생활이 가능하였다.

Purpose: This study was examined the effect of training using a Virtual Reality System on the sitting balance and Activities of Daily Living for patients with a spinal cord injury. Methods: The subjects were divided into an experimental (6 persons) and control group (5 persons). The experimental group trained the 5 programs, three times per week for 6 weeks using the Virtual Reality System and five days for week using conventional physical therapy. The control group trained five days for a week using conventional physical therapy. Results: The difference in the mean Spinal Cord Independence Measurement (SCIM) score in the experimental and control groups was increased to 8.33 and 6.60 (p=0.79), respectively. The difference in the mean functional reaching test in experimental and control group increased to 4.21 and 1.09 (p=0.25), respectively. The difference in the mean sitting time in experimental and control group increased to 41.05 and 10.33 (p=0.66), respectively. There was a difference in the mean of all variances but these differences were not statistically significant. Conclusion: These results suggest that training using the Virtual Reality System increased the SCIM, functional reaching test and sitting time in people with a spinal cord injury.

Objective : This study investigated the effect of intensive weight shift training (IWST) on the ability to balance in a sitting posture of children with spastic cerebral palsy (SCP). Methods : One child with spastic diplegia participated in this study for a total of 8 weeks using the ABA experimental design. For the pre-intervention period (A1), general physical therapy (GPT) for children with SCP was performed. The intervention period (B1 and B2), GPT and IWST were conducted for children with SCP, and GPT was conducted again for the post-intervention period (A'1 and A'2). Trunk control capacity was measured using the Korean Trunk Control Measurement Scale (TCMS-K) and Biorescue (RM Ingenierie, France). Results : All TCMS-K variables increased from A1 to B2, and decreased from B2 to A'2. The total area with limit of stability (LOS) increased from A1 to B2, and decreased from B2 to A'2. The ratio of the left/right (Lt/Rt) and anterior/posterior (Ant/Post) LOS area was closer to 1, meaning symmetry, in B2 than in A1. The ratio of the Lt/Rt LOS area decreased further from 1 in A'2 than in B2. The ratio of the Ant/Post LOS area was closer to 1 in A'2 than in B2. Conclusion : IWST had a positive effect on the improvement of balance in the sitting posture of a child with SCP. The results suggest that IWST might help to improve the balance abilities of children with SCP for independent sitting, postural control, and activities of daily living.

Purpose : This research intends to identify the effects of game-based weight bearing exercises on balance, muscular activation, sit to stand to sit motions of stroke patients. Method : 30 patients who were diagnosed as hemiplegia by stroke less in than a year were sampled and they were classified into two group, one of which was game-based weight bearing balance exercise group, and the other was functional weight bearing exercise group. 15 people were randomly selected for each group. Each exercise was coordinated by this research for 8 weeks, 5 days a week. 3D motion analyzer was used to measure the sit to stand to sit motions and a stopwatch was used to measure the time for stand-up motions for 5 times. Result : In terms of analyzing sit to stand to sit motions by phases, game-based weight bearing balance exercise group showed significant reduction compared to functional weight-bearing exercise group in phase I, II, III, IV and total time. In terms of functional stand-up performance analysis, game-based weight bearing balance exercise group showed significant reduction compared to functional weight-bearing exercise group in 5 times stand-up examination. Conclusion : It was verified that game-based weight bearing balance exercise had positive impact on function recovery of stroke patients by enhancing sit to stand to sit capabilities. It is considered that game-based exercise was an effective intermediary for functional improvement of stroke patients, while also inducing consistent and voluntary participation by causing interest and motivation.

The purpose of this study was to investigate the activity of the transverse abdominal muscle resulting from changed posture by measuring the thickness of the transverse abdominal muscle in a supine posture, a slouched sitting posture, and an erect sitting posture. The subjects of the study were 28 patients with cerebral palsy. All their transverse abdominal muscles at the end of inhalation were measured at supine, slouched sitting (S sitting) and erect sitting (E sitting) postures by using ultrasonography, and then their dynamic sitting balance was measured at S sitting and E sitting postures by using BioRescue. For the statistical analysis, the Kruskal-Wallis test and the Wilcoxon signed-rank test were used to compare the differences among each the postures. The results were as follows. The thickness of the transverse abdominal muscle when comparing the supine posture and the S sitting posture showed no statistically significant difference. But the E sitting posture showed a statistically significant difference as compared with the others. In addition, the dynamic sitting balance in comparing the S sitting and E sitting postures showed a significant difference. In conclusion, the E sitting posture has a more positive effect on postural control and balance than generally taking the S sitting posture, for the sitting posture of a patient with cerebral palsy. It is suggested that patients with cerebral palsy mainly experiencing a sedentary life or being in a wheelchair should be seated in the E sitting posture during their daily life, and it may be necessary to continue to monitor and manage the proper E sitting posture.

This paper presents the development of a robotic system for rehabilitation of the trunk's ability to maintain postural control under different balance conditions. The system, developed with extensive input from rehabilitation and biomedical engineering experts, consists of a seat mounted on a robotic mechanism capable of moving it with four degrees of freedom (3 rotational and 1 translational). The seat surface has built in instrumentation to gauge the movements of the user's center of pressure (COP) and it can be moved either to track the movements of the COP or according to operator given commands. The system allows two types of leg support. A ground mounted footrest allows participation of legs in postural control while a seat connected footrest constrains the leg movement and limits their involvement in postural control. The design evolution over several prototypes is presented and computer aided structural analysis is used to determine the feasibility of the designed components. The system is pilot tested by a stroke patient and is determined to have potential for use as a trunk rehabilitation tool. Future works involve more detailed studies to evaluate the effects of using this system and to determine its efficacy as a rehabilitation tool.
