OBJECTIVE: The objective of this study was to investigate the effects of botulinum toxin type A injections in reducing upper limb muscular spasticity and in improving motor function in children with cerebral palsy. DESIGN: Fifteen children with spastic cerebral palsy who were undergoing regular physical and occupational therapy were enrolled. Botulinum toxin type A injections in clinically indicated target muscle groups were administered after the children had received 3 mo of therapy. A follow-up study was carried out at 6 wk and 12 wk, respectively, after the botulinum toxin type A injections. The main outcome measurements included the Modified Ashworth Scale, the upper limb Physician's Rating Scale, the Bruininks-Oseretsky Test of Motor Proficiency, and the self-care domain of the Pediatric Evaluation of Disability Inventory. RESULTS: The reduction of spasticity in the treated muscle groups differed significantly between the control period and both study periods. Improvements on the Physician's Rating Scale score during the study period also differed significantly as compared with improvements during the control period. There was a significant difference in the improvement of fine motor skills, as measured with Bruininks-Oseretsky Test of Motor Proficiency, between the control period and both study periods. Improvements in self-care capability differed significantly between the control period and 12 wk after botulinum toxin type A treatment, but not between the control period and at 6 wk after treatment. Muscle strength of grasp and pinch did not differ significantly between the control and the study period. Distribution of body parts involvement, disease severity, and function in daily living activities had no significant correlation with functional improvement after the treatment. CONCLUSIONS: Our findings support the premise that botulinum toxin type A injections are effective in reducing upper limb spasticity and in improving movement pattern and fine motor function of patients with spastic cerebral palsy. A reduction in caregivers' burden and improved quality of life were demonstrated through the study period. 相似文献

Background and purpose. Three-dimensional movement in the upper limb presents a challenge for functional management of regional spasticity. Potential toxicity of botulinum toxin limits the number of muscles which may be injected in any one session. Serial injection may offer a solution, but carries theoretical risk of development of resistance due to antibody formation. This article reviews a small case series, gathered in a post-acute neuro-rehabilitation setting, to evaluate the use of serial botulinum toxin injection in terms of goal achievement and clinical evidence for toxicity or resistance.Methods. Nine patients with regional spasticity following acute stroke or brain injury had serial injection of botulinum toxin to muscle groups around the shoulder, elbow and/or wrist. Injection was followed by splinting/physiotherapy as appropriate. Goal attainment scaling was used to assess outcome.Results. Functional goals achieved were reduction of pain (n = 6/7) associated reaction (n = 4/5) or care needs (n = 5/6), improved gait (n = 2/3) or independence in self-care (n = 2/5). Two ‘golden responder’ cases are presented in detail to demonstrate resolution of symptoms with up to four serial injections of botulinum toxin over a period of up to 6 months. No clinical evidence of toxicity or resistance was seen in any case.Conclusion. These preliminary findings suggest that serial botulinum toxin injection followed by appropriate physiotherapy/splinting may provide effective treatment for regional spasticity. Resistance has not presented a problem in this post-acute situation, where treatment has not been required beyond a few months. Ongoing evaluation is underway. 相似文献

The lowest effective dose of botulinum A toxin in adult patients with upper limb spasticity 总被引:2,自引:0,他引:2
Objective: To define the lowest effective dose of botulinum toxin type A (Dysport®) and safety in the treatment of adult patients with upper limb spasticity.
Design: This was a prospective, randomized, double-blind, dose-ranging study. Patients received either a placebo or one of three doses of Dysport® (350, 500, 1000 U) into five muscles of affected arm by anatomical and electromyography guidance. Efficacy was assessed periodically throughout the 6-month study period by the Modified Ashworth Scale (MAS), the Action Research Arm Test (ARA), the Barthel Index (BI) and the Visual Analogue Pain Scale (VAS).
Results: Fifty patients were recruited. The four study groups were comparable at baseline with respect to their demographical characteristics and severity of spasticity. All doses of Dysport® studied showed a significant reduction from baseline of muscle tone and pain compared to placebo. However, the effect of functional disability was best at a dose of 500 U and the peak improvement was at week 8 after injection. A dose of 1000 U Dysport produced such an excess degree of muscle weakening that the number of randomized patients was reduced to five. BI and ARA of all patients were decrease after injection. No other adverse event was considered related to the study medication.
Conclusion: This study suggests that treatment with Dysport® reduces muscle tone in adult patients with upper limb spasticity. The optimal dose for treatment of patients with residual voluntary movement in the upper limb appears to be 500 U. 相似文献

OBJECTIVES: To present data about the effect of botulinum toxin injection on the upper limb of stroke patients. METHODS: We used the Medline data bank. Analysis took into account the international classification of functioning and disability. Important technical or pragmatic points were analysed separately. RESULTS: Botulinum toxin reduces spasticity of the injected muscles, with a mean gain of about 1 point on the Ashworth scale in the 4 to 6 weeks post injection, but with a large variability. This is associated to an increase in the passive range of motion, especially at wrist, and at times to a facilitation of active movements, when they are still possible. Improvement in functional tests is observed when fair proximal and distal motricity persists. Reduction in the dependence in daily living activities has not been shown by group studies. Several patients have an improvement in using the hand for blocking and transporting objects, mainly in a facilitating position (pronation, partial wrist flexion). Comfort of patients and caregivers is more regularly improved. Results are partially predictable; improvement in function is observed in patients with fair distal motricity (extension) and low spasticity, and improvement in comfort in those with severe spasticity and low motricity. CONCLUSION: Further studies are required, on one hand for better assessment of distal functional improvement, on the other hand at earlier phases of the disease. 相似文献

OBJECTIVE: To test the hypothesis that intramuscular (IM) botulinum toxin type A (BTX) reduces excessive muscle tone in a dose-dependent manner in the elbow, wrist, and fingers of patients who experience spasticity after a stroke. DESIGN: Randomized, double-blind, placebo-controlled, multicenter, 24-week trial. SETTING: Six academic and 13 private US outpatient medical centers. PARTICIPANTS: Ninety-one patients with a mean age of 60 years (range, 30-79 y). Mean time elapsed from ischemic or hemorrhagic stroke to study enrollment was 25.8 months (range, 0.9-226.9 mo). INTERVENTIONS: Up to 2 treatments of placebo, or 90, 180, or 360U of BTX. Concurrent splinting and physical therapy protocols were permitted, but no changes were allowed during the study. MAIN OUTCOME MEASURES: Wrist, elbow, and finger flexor tone assessed by the Modified Ashworth Scale, physician and patient global assessments, pain, FIM instrument, and Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). RESULTS: Muscle tone decreased more with injections of BTX than with placebo in the wrist flexors at weeks 1, 2, 3, 6, and 9 (P< or =.026); in the elbow flexors at weeks 1, 2, 3, 4, 5, and 9 (P< or =.033); and in the finger flexors at weeks 1 and 3 (P< or =.031). A dose-dependent response was generally observed in tone reduction but not in pain, FIM, or SF-36 measures. CONCLUSIONS: IM BTX reduced muscle tone in a dose-dependent manner in the elbow, wrist, and fingers of patients who experience spasticity after a stroke but did not appear to affect global quality of life or disability. 相似文献

INTRODUCTION: It is now demonstrated that botulinum toxin can improve upper limb spasticity after stroke. OBJECTIVES: This study was designed to assess the efficacy of botulinum toxin on upper limb spasticity with an individual approach. METHODS: Prospective study on 18 patients who had disabling spasticity of upper limb after stroke. For each patient, the treatment's target was fixed preliminary to botulinum toxin injection. Evaluation of efficacy (Ashworth scale and predefined targets) was performed at 1 month and treatment continuation was decided individually. RESULTS: A beneficial effect was reported by most patients when the treatment was aimed at improving comfort or quality of life. In one case, the treatment was designed to improve grasping. In that case, no effect was reported. For three patients, a neurotomy was performed in order to obtain a long lasting effect. For nine patients, repeated injections were decided. For the six other patients, no long-standing treatment was performed. DISCUSSION: This study confirms that botulinum toxin can improve comfort of patients with upper limb spasticity. On the base of our experience, we discussed contribution of botulinum toxin to enhance and optimise strategies for the treatment of focal upper limb spasticity with emphasis on the comparison with selective neurotomy. 相似文献

BackgroundBotuloscope is a cohort study supported by a French public grant and aiming to evaluate a 1-year treatment of the post-stroke spastic upper limb with botulinum toxin type A (BoNT-A) in terms of individual satisfaction with respect to personalized goals and quality of life.MethodsThis was an open-label prospective, multicentric study (11 French centres) that followed 330 adults [mean (SD) age 53.7 (13.7) years] over 1 year; participants had ranked 5 therapeutic goals at inclusion [mean (SD) 5.1 (7.3) years post-stroke], had severe hemiparesis [median motricity index (MI) 40 (Q1–Q3 24 to 60)], and were assessed at inclusion (M0) and at month 3 (M3) and M12. Outcome criteria were: spasticity, range of motion, pain [visual analog scale (VAS)], motor function [Modified Ashworth Scale (MAS)] and activities (MI; Frenchay Arm Test), and overall satisfaction with the achievement of each goal (VAS) and quality of life (Reintegration to Normal Life Index). Criteria at M0 and M12 were compared. Adverse effects were also collected, as were medication changes.ResultsThe primary goal was comfort and activities for 63% of participants and motor function for 36%. Participants underwent a mean of 2.4 injection sessions, 19% causing adverse effects. The greatest spasticity attenuation occurred with wrist flexors (median decrease in MAS −2 [Q1–Q3; −2 to −1], P < 10−3). Fewer individuals took oral anti-spastic drugs (56% at M12 vs 50% at M0; P < 10−2). Range of motion increased by 16°, on average (13 to 19; P < 10−3) for wrist extension. Pain prevalence decreases at rest (29% at M0 vs. 19% at M12; P < 10−4) and during mobilization (64% vs. 43%; P < 10−4), and fewer participants took analgesics (25% vs. 17%; P < 10−3). Satisfaction was high for the goals “hand hygiene” and “pain release” and moderate for “improvement in upper limb function”. However, function was more improved for participants who selected this goal as the first priority than others (P < 10−2). Overall, 22% had the goal “improving gait and balance”, which was reasonably achieved at M12. Quality of life improved markedly [median 8 (4 to 11) vs. 6 (3 to 10); P < 10−4]. Prevalence of complete dissatisfaction with the first objective was 10% to 15%.ConclusionThis is the first long-term follow-up of BoNT-A treatment for upper limb spasticity involving a large cohort independent of industry. Quality of life was improved by treating upper limb spasticity with BoNT-A, even at 5 years post-stroke. Personalizing objectives of the treatment amplified its efficacy. BoNT-A was a powerful analgesic when pain was spasticity-related. Treating the spastic upper limb also improved balance and gait abilities. 相似文献

In recent years, local injections with Botulinum toxin type A (BtxA) have become the treatment of choice for dystonia. However, several studies have demonstrated its efficacy and safety in the treatment of focal spasticity as well. These studies have shown efficacy and safety in upper limb spasticity treatment at a total dose between 500 and 1500 units of Dysport per injection session. While injections in upper arm muscles are easily administered without EMG-guidance, we recommend EMG-guidance for lower arm and finger muscles. In addition to functional improvement, BtxA treatment may also be considered for the following reasons: treatment of spasticity associated pain or painful muscle spasms, improved hygiene, facilitation of care, prevention of skin breakdown, and improved positioning of the upper limb. The definition of a realistic treatment goal, in agreement with the patient, as well as adjunctive physiotherapy are prerequisites for a successful BtxA treatment. Dose recommendations are given in Table 1. 相似文献
