A Randomised Controlled Study to Investigate Effects of Bobath Based Trunk Control Training on Motor Function of Children with Spastic Bilateral Cerebral Palsy

Purpose: The aim of this study was to investigate the effects of trunk control on motor function, which plays an important role in the daily activities of children with Cerebral Palsy (CP) and is often observed as a deficiency in children with CP. Material and Methods: Forty children with spastic bilateral CP, ages between 3 to 10 years and with Gross Motor Function Classification System (GMFCS) level I, II, and III were included in this study. Children were divided into two groups using randomization and in training group;Bobath Therapy for trunk control in addition to classical physiotherapy programs was performed for 45 minutes, for two days a week, for 6 weeks. In control group, existing physiotherapy program, 45 minutes for two days a week, continued. Any addition was not made into the existing program of the control group. Modified Ashworth Scale (MAS), Pediatric Berg Balance Scale (PBBS), Trunk Control Measurement Scale (TCMS), 1 Minute Walking Test (1MWT), Timed Up and Go Test (TUG) were applied to both groups before and after 6 weeks. Moreover, trunk muscle strength of children was evaluated. Results: After therapy, differences were found in results of MAS and PBBS, and trunk extensor strength between the training group and the control group in favor of the training group (p Conclusion: This study shows that adding exercises which aim trunk to conventional physiotherapy and exercise programs of children with CP, affects motor function positively.

Role of Trunk Rehabilitation on Trunk Control, Balance and Gait in Patients with Chronic Stroke: A Pre-Post Design

Purpose: Although proximal stability of the trunk is a prerequisite for balance and gait, to determine the role of trunk rehabilitation on trunk control, balance and gait in patients with chronic stroke is yet unknown. Method: Fifteen sub-jects (post-stroke duration (3.53 ± 2.98) years) who had the ability to walk 10 meters independently with or without a walking aid;scoring ≤ 21 on Trunk Impairment Scale (TIS), participated in a selective trunk muscle exercise regime, consisting of 45 minutes training per day, four days a week, and for four weeks duration in an outpatient stroke reha-bilitation centre. Results: The overall effect size index for trunk rehabilitation was 1.07. This study showed large effect size index for Trunk Impairment Scale (1.75), Berg Balance Scale (1.65) than for gait variables (0.65). After trunk rehabilitation, there was a significant improvement for gait speed (p= 0.015), cadence (p= 0.001) and gait symmetry (p=0.019) in patients with chronic stroke. In addition, all the spatial gait parameters had a significant change post-intervention. There was no significant change in temporal gait parameters with the exception of affected single limb support time. The level of significance was set at p < 0.05. Conclusion: The exercises consisted of selective trunk movement of the upper and the lower part of trunk had shown larger effect size index for trunk control and balance than for gait in patients with chronic stroke. Future randomized controlled studies incorporating large sample size would provide insight into the effectiveness and clinical relevance of this intervention.

不同躯干约束下蹲姿对人体下肢运动学和动力学的影响

目的 探究躯干控制对青年群体亚洲蹲和西方蹲时下肢运动生物力学特征的影响,为深蹲训练的应用和推广提供实证性依据。方法 24名健康男性青年大学生在带杆、无杆控制条件下进行亚洲蹲和西方蹲,运用红外光点运动捕捉系统和三维测力台采集其下肢运动学和动力学特征。通过Cortex-642.6.2软件,根据欧拉角方法计算获得下肢三维角度,运用逆动力学方法得到三维力矩。通过2×2重复设计的双因素方差分析检验躯干控制和深蹲姿势对下肢运动特征的影响。结果 躯干控制和深蹲姿势对运动学和动力学参数均无显著性交互作用(P>0.05)。西方蹲具有较大的膝关节屈曲角、髌股关节接触力峰值、髋膝伸展力矩峰值之比,较小的踝关节背屈角、髋关节屈曲角(P<0.05)。带杆深蹲具有较大的踝关节背屈角、髌股关节接触力峰值和髋关节屈曲角,较小的膝关节屈曲角、髋膝伸展力矩峰值之比(P<0.05)。结论 西方蹲有助于训练伸髋肌群肌力,亚洲蹲则有助于训练伸膝肌群肌力。西方蹲髌股关节接触力峰值显著大于亚洲蹲,故推荐髌股关节痛患者采用亚洲蹲。带杆深蹲可补偿人体平衡,建议由于踝关节背屈活动范围受限或胫骨前肌无力人群可以考虑进行带杆深蹲等躯干控制训练,有助于提高深蹲时下肢稳定性。

A review on assessment and treatment of the trunk in stroke A need or luxury

Trunk function has been identified as an important early predictor of functional outcome after stroke and the same deteriorates on both contralateral and ipsilateral sides of the body following stroke. The primary contribution of the trunk muscles is to allow the body to remain upright, adjust weight shifts, and control movements against constant pull of gravity and is considered central key point of the body. Proximal stability of the trunk is a pre-requisite for distal limb mobility, balance, gait and functional activities and its positive correlation in hemiplegia has been demonstrated in a cross- sectional study. Both isokinetic and handheld dynamometer muscle strength testing demonstrated the weakness of bilateral trunk flexors, extensors and rotator muscles in both acute and chronic hemiplegic patients. This was confirmed by electromyography analysis which identified poor bilateral trunk muscles activity in patients with stroke. Trunk impairment scale is sensitive to evaluate the selective muscle control of upper and lower trunk, and it has been reported that lateral flexion of the trunk is easier than rotation of the trunk and the clinical observation concurs to the difficulty in lower trunk rotation of stroke patients. However, trunk exercises given early after stroke could produce enhanced balance performance post- stroke. This review attempts to report the evidence supporting the involvement of the trunk and its influence on balance and functional performance in post-stroke hemiplegia.

Corticoreticular tract lesion in children with developmental delay presenting with gait dysfunction and trunk instability

The corticoreticular tract （CRT） is known to be involved in walking and postural control. Using diffusion tensor tractography （DTT）, we investigated the relationship between the CRT and gait dysfunction, includ- ing trunk instability, in pediatric patients. Thirty patients with delayed development and 15 age-matched, typically-developed （TD） children were recruited. Fifteen patients with gait dysfunction （bilateral trunk instability） were included in the group A, and the other 15 patients with gait dysfunction （unilateral trunk instability） were included in the group B. The Growth Motor Function Classification System, Functional Ambulation Category scale, and Functional Ambulation Category scale were used for measurement of functional state. Fractional anisotropy, apparent diffusion coefficient, fiber number, and tract integrity of the CRT and corticospinal tract were measured. Diffusion parameters or integrity of corticospinal tract were not significantly different in the three study groups. However, CRT results revealed that both CRTs were disrupted in the group A, whereas CRT disruption in the hemispheres contralateral to clinical mani- festations was observed in the group B. Fractional anisotropy values and fiber numbers in both CRTs were decreased in the group A than in the group TD. The extents of decreases of fractional anisotropy values and fiber numbers on the ipsilateral side relative to those on the contralateral side were greater in the group B than in the group TD. Functional evaluation data and clinical manifestations were found to show strong correlations with CRT status, rather than with corticospinal tract status. These findings suggest that CRT status appears to be clinically important for gait function and trunk stability in pediatric patients and DTT can help assess CRT status in pediatric patients with gait dysfunction.

A NEW CALL CONTROL SCHEME OF PUSH-TO-TALK SYSTEM

For Push-To-Talk (PTT) system based on Public Mobile Data Network (PMDN), the end-to-end time delay is the key aspect of the user's experience. The Push-Over-Cellular (POC) scheme defined by Open Mobile Alliance (OMA) is based on the VoIP phone model and use SIP protocol as the call control scheme. The call setup time delay in SIP may reach to several seconds, which is unac-ceptable for the PTT service. In this paper, we provide a new call control scheme for PTT system based on PLMN network. By combining the apriority knowledge of PTT call model and the priority control scheme, we encapsulate the signaling message and the voice data into a same data packet, when the user push the button, the voice and the call control signaling are sent to the server at the same time. So the long time delay of call setup procedure of POC scheme can be eliminate. The end-to-end call delay can be decreased significantly. The experiment result based on the commercial CDMA2000 1X network of China Unicom shows that the call delay can be decreased to 600 ms, which approach to the traditional trunk communication system's requirement.
