Central limb spasticity is a common complication after central nervous system injury, in which hand flexion spasticity often leads to the loss of the patient’s ability to move. Reducing muscle tone and relieving spasticity are the prerequisites for restoring limb function. T1 rhizotomy, which has been proposed in recent years, has proven to be effective in the treatment of central hand flexion spasticity. This consensus summarizes the etiology, symptoms, functional assessment of central hand flexion spasticity, and surgical indications for T1 rhizotomy, surgical principles and procedures, and rehabilitation program. The standardized protocol of T1 rhizotomy for the treatment of central hand flexion spasticity is proposed for the reference of clinicians in the process of diagnosis and treatment, with the aim of further improving the treatment level for central hand flexion spasticity.
Objective To explore the components of passive movement resistance in the wrist flexor in subjects after stroke, and investigate the correlations between these components and clinical scales such as Modified Ashworth Scale (MAS) and Fugl-Meyer Assessment (FMA). Methods From March to August 2017, a cross-sectional study was performed in 15 stroke survivors in the Department of Rehabilitation Medicine, the First Affiliated Hospital, Sun Yat-sen University. MAS and FMA were assessed by an experienced physical therapist. Components of passive movement resistance in the flexors of wrist and finger were recorded by NeuroFlexor (Aggro MedTech AB, Solna, Sweden), then the average resisting force in one second ensued the passive stretch at 5°/s was took as peak resisting force (PRF). The PRF between paretic side and non-paretic side was compared. Spearman’s rank correlation was used to test the relation between the components and clinical scales. Results The PRF of the paretic side during the slow passive stretch (5°/s) was significantly higher than that of the non-paretic side [(10.49±1.65) vs. (8.98±1.11) N, P<0.05]. Correlations between MAS and the components/PRF were insignificant (P>0.05). FMA had a significant correlation with neural component of the paretic side (rs=–0.645, P=0.009). Conclusions The higher PRF of slow passive stretch in the paretic side may be attributed to the higher muscle stiffness. Neural component of the paretic wrist is correlated with FMA. These findings could be applied in clinical evaluation of functional performance of the wrist muscle of stroke survivors.
【摘要】 目的 观察悬吊运动系统治疗（sling exercise therapy， SET）联合神经发育疗法治疗对痉挛型脑性瘫痪儿童肌张力及日常生活活动能力（activities of daily living，ADL ）的影响。 方法 2008年8月-2009年3月收治的40例双下肢痉挛型脑性瘫痪儿童纳入研究。根据随机数字表法分为治疗组与对照组，每组各20例。对照组与治疗组均采用神经发育疗法进行康复训练，治疗组在神经发育疗法基础上配合悬吊运动系统治疗。观察两组患儿治疗1、3个月时肌张力与ADL变化。 结果 治疗1个月时，治疗组患儿肌张力缓解明显优于对照组（P＜0.05），3个月时，治疗组肌张力缓解程度明显优于对照组。两组ADL评分比较，治疗组ADL评分改善情况明显优于对照组（P＜0.05）。 结论 悬吊运动系统治疗联合神经发育疗法可明显缓解痉挛型脑性瘫痪患儿童肌张力，提高ADL。【Abstract】 Objective To observe the effects of sling exercise therapy (SET) combined with neurodevelopmental therapy on muscle tension and activities of daily living (ADL) of children with spastic cerebral palsy. Methods Forty children with spastic cerebral palsy on bilateral lower limb were selected in our study. The children were randomly divided into a treatment group and a control group, 20 children in each group. Both the two groups were accepted rehabilitation training by neurodevelopmental therapy, while the treatment group was received SET as cooperate cure based on the neurodevelopmental therapy. The changes of muscle tension and ADL on the one and three months after treatment were observed. Results On the one and three months after treatment, the remission of muscle tension and improvement of ADL score were better than those in the control group, the differences were statistically significant(Plt;0.01). Conclusion SET combined with neurodevelopmental therapy can relieve the muscle tension, and improve the ADL of children with spastic cerebral palsy.
ObjectiveTo investigate the expression changes of the receptor activator of nuclear factor-κB ligand (RANKL) in the peripheral blood of patients with aseptic loosening of the implant after total hip arthroplasty (THA) by comparing with that of patients with femoral neck fracture and to analyze the correlation between RANKL expression and aseptic loosening. MethodsBetween January 2008 and January 2013,the peripheral blood were harvested from 58 patients with aseptic loosening of the implant after THA (trial group) and 63 patients with femoral neck fracture (control group).The 2 groups were well matched,with no significant differences in age and gender (P>0.05).The expressions of the RANKL mRNA and RANKL protein were evaluated by quantitative real-time PCR and Western blot respectively.At the same time,the concentration of RANKL was also measured by ELISA. ResultsThe expression of the RANKL mRNA in the trial group was 18.30±1.09,which was significantly higher than that of control group (1.00±0.05)(t=125.390,P=0.000).The relative RANKL protein expression values in trial group and control group were 0.856±0.254 and 0.404±0.102 respectively,showing significant difference (t=13.032,P=0.000).The results of ELISA showed that the concentration of RANKL in trial group [(3.553 5±0.129 7) ng/mL] was significantly higher than that of control group [(1.912 3±0.126 2) ng/mL] (t=18.124,P=0.000). ConclusionThe high RANKL expression in peripheral blood is probably correlated with aseptic loosening of the implant in patients undergoing THA,which possibly is the prognostic factor of aseptic loosening of the implant.
