12 Clinical Trials for Various Conditions
The participants of this study will have AUL spasticity and have a need for botulinum toxin type A injections. AUL spasticity is where people develop tightening or stiffness of the muscles in the arms. Botulinum toxin type A is used for the treatment of spasticity in addition to physiotherapy. This study will ask participants to describe their experience living with AUL spasticity. This information will be used to assess the Arm Activity Measure (ArmA). ArmA is a scale designed to assess upper limb function in people with AUL spasticity. This study could suggest changes to the ArmA to improve its suitability for people with AUL spasticity or even the development of a new scale.
The purpose of this clinical study is to assess whether AbobotulinumtoxinA (Dysport®) injections in upper and lower limbs accompanied with a personal exercise plan called "Guided Self-rehabilitation Contract" (GSC) can improve voluntary movements in subjects with hemiparesis.
The purpose of this study is to evaluate the limb functional improvement after contralateral C7 root transfer in stroke patients.
Stroke survivors experience motor deficits, weak voluntary muscle activations, and low weight-bearing capacity that impair ambulation. Restoring motor function is a priority for people post-stroke, whose gait patterns are slow, and metabolically inefficient. The role of the ankle is crucial for locomotion because it stores mechanical energy throughout the stance phase, leading to a large activation of plantarflexor muscles during push-off for propulsion. After a stroke, paretic plantarflexors undergo changes in their mechanics and activation patterns that yield diminished ankle power, propulsion, and gait speed. Recovery of lost plantarflexor function can increase propulsion and mitigate unnatural gait compensations that occur during hemiparetic walking. In the stance phase, dorsiflexion is imposed at the ankle and the plantarflexors are loaded, which results in excitation of group Ia and II afferents, and group Ib afferents. Load sensing Ib afferents are active in mid-late stance, and through spinal excitatory pathways, reinforces the activation of plantarflexors and propulsive force generation at the ankle. Targeting the excitability of the load sensitive Ib excitatory pathway, propulsive soleus activity and resulting force generation (and thereby gait speed) can be improved after stroke. The long-term research goal is to develop a novel hybrid gait paradigm integrating operant conditioning and powered wearable devices to advance neuro-behavioral training and enhance locomotor ability after stroke. The overall objectives are to 1) modulate the soleus muscle loading response within the stance phase, and 2) develop a dynamic protocol to operantly condition the soleus response in stroke survivors. The central hypothesis is that enhancing the soleus loading response in mid-late stance phase through operant up-conditioning can increase plantarflexor power and forward propulsion after stroke. In working towards attaining the research objective and testing the central hypothesis, the objective of this pilot study is to modulate the soleus loading response in the stance phase during treadmill walking. The specific aims in this study are to 1) apply ankle perturbations in mid-late stance phase combining a control algorithm and a powered device to characterize the changes in soleus EMG between perturbed and unperturbed (i.e., when no perturbations are applied) step cycles in 15 able-bodied individuals; and 2) determine the feasibility of the wearable ankle device and its algorithm in 5 participants with hemiparesis and gait deficits due to a stroke. The testing of the device and its algorithm will provide foundational evidence to adjust the soleus stimuli continuously and reliably, and develop the new walking operant conditioning protocol for stroke survivors. An expected outcome in this pilot is to lay the groundwork to develop the soleus up-conditioning protocol as a potential strategy to improve paretic leg function. If successfully developed, this new protocol proposed in a subsequent study will be the first neurobehavioral training method that targets spinal load-sensitive pathways to improve ankle plantarflexor power and forward propulsion after stroke.
The goal of this study is to test the efficacy of transcranial direct current stimulation combined with bimanual training on hand function in children with unilateral spastic cerebral palsy (USCP). Children who enroll in the protocol will be randomized to receive either sham (not stimulating) tDCS plus bimanual training, or active (stimulating) tDCS plus bimanual training.
The purpose of this study is to investigate if two courses of five consecutive sessions of noninvasive spinal stimulation paired with peripheral nerve stimulation at the forearm provided by an investigational device (Doublestim™/ MyoRegulator™ System - PathMaker Neurosystems Inc.) are able to improve wrist stiffness and motor function, when combined with intensive robotic wrist training program in participants with chronic spastic hemiparesis after stroke.
The purpose of this study is to evaluate if 5 consecutive sessions of PathMaker anodal DoubleStim treatment, which combines non-invasive stimulation of the spinal cord (tsDCS- trans-spinal direct current stimulation) and of the median nerve at the peripheral wrist (pDCS-- peripheral direct current stimulation), can significantly reduce spasticity of the wrist and hand after stroke.
The investigators hypothesize that children with spastic cerebral palsy will show greater improvements in gross motor function, associated developmental skills and growth after the 3 months of myofascial structural integration treatment, a form of deep massage, than they showed after a 3- or 6-month pre-treatment waiting period. The investigators further hypothesize that children with spastic CP will maintain their gains in gross motor function for ≥ 3 months after completion of MSI treatment.
The goal of this study is to define the efficacy of fully remote home-based BCI therapy in chronic hemiparetic subcortical stroke patients. A randomized controlled study using the integrated remote BCI system will be tested against standard exercise therapy to determine the efficacy of motor improvement in chronic stroke patients with an upper extremity hemiparesis. Specifically, the integrated BCI system will include 1) the remote screening and motor assessment system for the upper extremity and 2) the BCI-controlled robotic hand exoskeleton (i.e. IpsiHand).
Stroke can lead to weakness and spasticity in the arm or hand. The purpose of this study is to optimize the design of gentle vibratory stimulation delivered to the hands of individuals with chronic stroke, and explore the effect on range of movement and spasticity.
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.
The purpose of this study is to see whether treating subjects for wrist rehabilitation following stroke with Botox® and robotic therapy is more effective than treatment with robotic therapy alone and no Botox®.
