Purpose : This study aims to examine effects of trunk strengthening exercise in three rigid cerebral palsy adolescents aged between 11 and 13 on their spinal segments and gait. Methods : 2A trunk strengthening program for proprioceptive neuromuscular facilitation was made focusing on improvement in their school life and mental and social activities during their school years, and then trunk strengthening exercise was applied to the three subjects for 30 minutes five times per week for four weeks. With the subjects in a static state, each group's gait analysis was made and maximum anterior flexion, maximum extension, maximum left and right lateral flexion, and cross rotation of the trunk were measured using Sonosens (Germany) prior to and after the intervention. Results : Assessment of spinal segment mobility with the subjects in a static state showed that the trunk muscle strengthening exercise increased their maximum joint movement angles from the right side to the center and rotational abilities of the cervical and lumbar spines. Gait analysis indicated increased movements in the thoracic and lumbar spines and relatively decreased anterior-posterior movement of the cervical spine. Conclusion : Trunk strengthening program is effective in enhancing spinal segment mobility and balance ability of cerebral palsy adolescents and considered able to be used together with diverse treatment interventions.

Objective : In 1983 Autosomal dominent spinocerebellar ataxia(ADCA) has been classified to four types by a useful clinical features according to Harding. Since 1993 ADCA referred to as SCA by molecular genetic characteristics. We focused on the improvement of clinical symptoms in SCA patient through oriental medical treatment. Methods ＆ Results : The assessment included neurophysiological examination and clinical symptoms. For example slow saccade, gaze limitation, upward and lateral, nystagmus, truncal and gait ataxia. The patient(M/30) was clinically charaterized by ocular abnormalities, trunkal and gait ataxia and the MRI showed atrophy of cerebellar vermis. The patient was taken both common acupuncture and Dong-Si venepuncture on Hwasan with herbal medicine. Before the treatment Rt. ocular movement were slowed and a significant eye fixation was observed always in abduction and intermittently presented trunkal and gait ataxia. During the treatment trunkal and gait ataxia has not been presented and ocular obnomalities changed to normal state. This case suggests the possibility of oriental medical treatment on SCA but further observation is needed on this patient.

In this paper, an algorithm to detect steps in hemiplegic patients using a 3-axis accelerometer a紅ached on the trunk was proposed. The proposed algorithm consisted of the signal pre-processing, the step detector, the classification of steps and the calculation of stride time. Two FIR band-pass filters were designed and steps were measured by the combination of filtered signals in the vertical and the anteroposterior directions. In addition, the classification of steps and the calculation of stride time were computed by using the detected steps and lateral signals. For the experiment, fourteen hemiplegic patients were participated and the linear accelerations of the trunk and foot switch signals were measured synchronously. To evaluate the system performance, the detected steps and initial contacts by the foot switch were compared. The average error between the steps and initial contacts was 0.024ms and the difference of the average stride time was 0.01s. Finally, all gait events were detected exactly. Results showed that the accelerometry could use for the gait evaluation in clinical rehabilitation therapies.

This study is the quasi-experimental study on the gait training rehabilitation. The purpose of this study is to prepare the baseline data for most suitable of gait while we were scrutinizing how the walking characters, functional walking ability, gait quality of stroke patients were affected by the gait on BWSTT (Body Weight Supported Treadmill Training) through the change of treadmill velocity and body weight support. To accomplish this purpose, this study used thirty subjects, more than 3 months post stroke, for rehabilitation who were divided between two gait training groups they received the neurophysiological physical therapy. For 6 weeks, 5 times a week for 15 minutes per session, the BWSTT group participated in 30 sessions structured speed-dependent treadmill training with 30% body weight supported, and the ratio of body weight support was gradually decreased as the patients advanced the capability of more self-support. The OGT(Over Ground Training) group received the same quantity of equal sessions like BWSTT. Firstly, we measured the absolute improvement of walking velocity (m/s), capacity(min/m) and cadence(steps/min) among walking characters. Secondly, we measured the functional walking ability such as Functional Ambulatory Category(FAC, score out of 5), Modified Motor Assesment Scale(MMAS, score out of 6) and Gait Quality Chart(score out of 41). Data analysis was performed with using SPSS 10.0 win program. The descriptive analysis was used to obtain average and standard deviation. The independent t-test and the paired t-test were used to compare both the groups about pre and post training test. Treatment effects were established by pre and post assessment. Subjects tolerated the training well without side-effects. Therefore, the results of this study were as follows; 1. There was a more significant difference from the improvement of walking velocity(0.09m/s), endurance(4.53min/m), cadence(4.20steps/min), FAC(0.26score), MMAS(0.33 score) and hip joint and pelvic of gait quality(0.39 score) ever before in the BWSTT group(p<.05). 2. There was a more significant increase from the walking velocity(0.01m/s) in the OGT group(p<.05). 3. There was a more statistical significant increase from comparing the average of walking velocity in both groups ever before(0.42m/s in BWSTT group and 0.31m/s in OGT group)(p<.05). There was a statistical significant difference from the average of cadence in both groups(61.87step/min in BWSTT group and 3.60steps/min in OGT group)(p<.05). As we can see from above, the findings suggest that BWSTT may be more effective than the OGT for improving some gait parameters such as gait velocity and cadency. This conclusion also suggest that BWSTT is more effective for the improvement of gait of stroke patients.

Previous studies have demonstrated the importance of joint angle errors mainly due to skin artifact and measurement errors during gait analysis. Joint angle errors lead to unreliable kinematics and kinetic analyses in the investigation of human motion. The purpose of this paper is to present the Joint Averaging Coordinate System (JACS) method for human gait analysis. The JACS method is based on the concept of statistical data reduction of anatomically referenced marker data. Since markers are not attached to rigid bodies, different marker combinations lead to slightly different predictions of joint angles. These different combinations can be averaged in order to provide a "best" estimate of joint angle. Results of a gait analysis are presented using clinically meaningful terminology to provide better communication with clinical personal. In order to verify the developed JACS method, a simple three-dimensional knee joint contact model was developed, employing an absolute coordinate system without using any kinematics constraint in which thigh and shank segments can be derived independently. In the experimental data recovery, the separation and penetration distance of the knee joint is supposed to be zero during one gait cycle if there are no errors in the experimental data. Using the JACS method, the separation and penetration error was reduced compared to well-developed existing methods such as ACRS and Spoor & Veldpaus method. The separation and penetration distance ranged up to 15 mm and 12 mm using the Spoor & Veldpaus and ACRS method, respectively, compared to 9 mm using JACS method. Statistical methods like the JACS can be applied in conjunction with existing techniques that reduce systematic errors in marker location, leading to an improved assessment of human gait.

Objective: The purpose of this study was to investigate the effects of fall experience and task complexity on gait performance in community-dwelling persons with chronic hemiparetic stroke. Design: Cross-sectional study. Methods: Thirty-three persons who had a history of stroke participated in this study. The participants included 18 persons (aged mean 54.0, mean score of 24.6 points on the Montreal Cognitive Assessment, MoCA) with fall experience (faller group) and 15 persons (aged mean 53.7, mean score of 24.7 points on the MoCA) without fall experience (non-faller group) in the previous six months. This study measured balance and gait performance at two different conditions (with/without 70% of water filled in a 200 cc cup). The participants were clinically assessed using the 10-meter walk test (10MWT), 6-minute walk test (6MWT), Berg Balance scale (BBS), Dynamic Gait Index (DGI), and Timed Up-and-Go (TUG) test. Results: After analyzation, persons in the faller group performed significantly better on the 10MWT, 6MWT, BBS, DGI, and the TUG test in the no-cup-carrying condition than those in the cup-carrying condition (p<0.05). The persons in the non-faller group also performed significantly better in all outcome measures with the no-cup-carrying condition than those in the cup-carrying condition (p<0.05). However, there was no interaction between fall experience and task complexity in the two groups. Conclusions: Our results showed that balance and gait performance depended on fall experience and task complexity but fall experience did not interact with task complexity. Clinicians should consider fall prevention and task complexity during therapeutic approaches in persons with hemiparetic stroke.

Purpose : The goal of this study was to identify the effects of treadmill walking training (TW) and ergometer bicycle training (EB) on gait and balance in stroke patients. Methods : The subjects consisted of 42 stroke patients. They were randomly divided to two groups: TW(n=20) and EB(n=22). Each group trained along with the conventional physical therapy, three times a week for six weeks. The ability of gait was assessed by the 10m walk test and Timed Up and Go test(TUG). The ability of balance was assessed by Berg Balance Scale(BBS) and Balance Performance Monitor(BPM). Results : There was no significant difference between the 10m walking test and TUG groups, but there was a statistical difference between before and after the training for all groups. The result of BBS that assessed balance showed a significant reduction between before and after the training for all groups, but there was no difference between the two groups. While the two groups showed no difference in the BPM assessment, only the EB showed a significant improvement of before and after the training in each group. Conclusion : The outcomes suggest that stroke patients can improve their gait and balance performance through the TW and EB trainings. Although dynamic mean balance showed significance from EB, no significant difference was found between two groups. Even though it cannot be determined through this study which training group is more effective among the above mentioned two, it could be suggested that each training is effective to gait ability and the ability of balance of stroke patients.
