Filter by:Neurologic changes caused by cerebral palsy (CP) result in adaptation of muscle architecture and function (e.g. shortened muscles and contractures). Stretching through immobilization (orthotic treatment) is one of the common interventions to bring the spastic muscle to growth. Positive outcomes of stretching through immobilization are increased range of motion and improved function. On the other hand, immobilization leads to disuse muscle atrophy. Hence, we hypothesize that combining a stretching through immobilization and muscle activity while controlling for foot deformity could be a superior treatment approach, which should lead to improved muscle morphology as well as function. The aim of the study is to examine the influence of two orthotic treatments (a standard regime and one new approach) on spastic plantar flexor muscles in children and adolescents with CP. The standard regime (stretching through immobilisation) includes a dynamic AFO (ankle-foot orthosis) used during day and night. The new approach combines stretching through immobilisation and allows for plantarflexor activity due to an innovative construction of the orthotic device. This prospective randomized controlled study will recruit 20 ambulant children and adolescents (aged 5 to 15 years) with cerebral palsy and equinus deformity (GMFCS = Gross Motor Function Classification System level I to III). Each child will be randomized and stratified according to age and GMFCS to one of two groups. The first group receives the standard treatment (stretching through immobilization) using custom-made ankle foot orthosis for 23 hours per day. The other group will be treated with the same orthosis at night (8 hours) and for 6 hours during the day but the remaining 10 hours will be treated with the foot shell only that corrects subtalar and Chopart joints but does not block the ankle joint movement, so that more activity of plantarflexors will be possible during the day. The intervention will last for 12 weeks. Each child will be examined at four occasions (8 weeks before intervention = control phase, at the beginning of the intervention and then 8 and 12 weeks later). The main outcome measure is the fascicle length measured using a 3D ultrasound (3DUS) imaging technique. Further parameters of interest span across the whole levels of ICF including clinical examinations, biomechanics of gait, muscle morphologic and mechanic properties and participations questionnaires.
This study assess the relationship between lower limb spasticity and trunk movements during static and dynamic balance in post-stroke patients who also underwent conventional physical therapy, visual feedback balance training and radial extracorporeal shock wave therapy intervention.
The course of AMN-related disabilities over time is poorly or incompletely understood due to a limited number of patients and lack of treatments. This study will help obtain a better understanding of the progression of disease with AMN and facilitate efficient clinical development of future interventional medications.
Spasticity is a common complication after many upper motor neurone disorders. Many surgical techniques have been introduced for patients with refractory spasticity though they are not without peri-operative risks. Cryoneurotomy is another procedure which is cheaper, faster and less invasive in comparison to other surgical interventions. While many studies support the use of cryoneurotomy for pain relief, there are not much studies on use of cryoneurotomy to manage spasticity. The purpose of this study to measure the effect of tibial nerve cryoneurotomy on electrophysiological and clinical spasticity measures in adult patients with spastic equinovarus or equinus foot, who will receive this procedure as a part of their treatment based on spasticity treatment available guidelines. The results will provide us valuable information like how long cryoneurotomy is effective, before regeneration happens.
Phase 2/3, randomized, double-blind, placebo-controlled, single-treatment, multicenter trial assessing the efficacy and safety of MYOBLOC for the treatment of upper limb spasticity in adults followed by an open-label extension safety trial.

Cerebral palsy(CP) consisted of a group of developmental disability in the field of motor function and is one of the major problems of pediatric neurology and at the present time there is no standard curative medical or surgical treatment for it .Stem cell therapy is one of a new and hopeful therapeutic methods of therapy for CP .This double blind study designed for the evaluation of safety and therapeutic effects of intrathecal hematopoietic and mesenchymal stem cells derived from allogenic umbilical cord in change and probable improvement of developmental functions of spastic CP participants between 4-14 years old and comparing with control group of CP participants without cell therapy . 108 cases recruited and randomly divided to 3 groups of 36 cases : hematopoietic stem cells derived from allogenic umbilical cord , Mesenchymal cells derived from allogenic umbilical cord and control group without injection and appearance simulating lumbar puncture without awareness of the patients and evaluators . Developmental functions and spasticity evaluated before intervention and will be done 1 , 3 , 6 and 12 months after injection . During this period neuro rehabilitation will be continued . Brain neuroimaging were done at the recruitment time and will be repeated after 12 months .
Measure pain and anxiety during a putative painful medical procedure (i.e., botulinum toxin injections) when Virtual Reality is employed compared to standard of care only using a Randomized Controlled Trial study design.
The stroke has been described as the third cause of death and main cause of disability in the worldwide population. About 60% of the survivors are able to walk following the rehabilitation process, however deficits on lower limbs functions often persists in most cases, affecting the gait and functional mobility. In this sense, several interventions are applied in the clinical practice to optimize the functional performance. Cryotherapy is one of the most used techniques aiming to reduce spasticity temporarily, allowing the training of functional tasks, such as walking. The aim of the present study is to evaluate the immediate effects of cryotherapy (ice pack) on neuromuscular performance, proprioception, passive resistance of dorsiflexors and plantarflexors muscles, and also on gait performance in chronic post-stroke subjects. Eighteen chronic hemiparetic subjects will participate in this crossover placebo-controlled trial. The order of intervention (cryotherapy or placebo) will be randomized. Fifteen days of washout period will be considered. The cryotherapy/placebo will be applied on the posterior area of the leg for 20 minutes. Initially Fugl Meyer will be applied. All other assessments will be performed before and after intervention: spasticity level, classified according to Modified Ashworth Scale; temporo-spatial and angular parameters for trunk, hip, knee and ankle during gait, using a motion analysis system (Qualysis AB, Gothenburg, Sweden); the proprioception (joint position sense), passive resistance to stretching, isometric and isokinetic torques during contractions of plantarflexors and dorsiflexors of the ankle, evaluated through isokinetic dynamometer. Concomitantly, bilateral activation of soleus, gastrocnemius, tibialis anterior and peroneus will be assessed by electromyography during isokinetic dynamometer assessment and gait. The following electromyographic variables will be analyzed: maximum activation amplitude, muscle onset, coactivation index between agonists and antagonists. For statistical analysis, normality (Shapiro Wilk) and homogeneity (Levene) tests will be applied. If the variables have a distribution considered normal and homogeneous, Two-way ANOVA with repeated measures will be applied. Otherwise, non-parametric statistics (Friedman test) will be applied. A significance level of 0.05 will be considered for all statistical tests.
This study evaluates a new rehabilitation approach for stroke survivors in the chronic phase of recovery in which the combination of drug therapy (cyproheptadine) and active movement practice (AMP) is used to encourage increased voluntary muscle control and strength.
