Strokes are one of the leading causes of long term disability and death in the United States. A stroke occurs when the blood supply to the brain is blocked, damaging parts of the brain. Many stroke survivors have difficulty completing dexterous hand movements and manipulating objects due brain damage in the sensorimotor cortex. Damage to these areas can cause decreased motor movements and tactile sensation on the affected side. Research shows that tactile sensation is necessary for maintaining grip, grading grip forces and decreasing object slippage. Therefore, it is important to address tactile sensation with motor performance during stroke rehabilitation to improve performance outcomes among stroke survivors.
The goal of lower limb rehabilitation after stroke is recovery of independent walking at home and in the community. Few stroke survivors achieve this goal. Suboptimal outcomes are due to the serious and intransigent nature of movement impairments caused by stroke and the scarcity of feasible and effective therapies that restore movement lost to stroke. Our team has developed a novel exercise intervention called CUped (pronounced cupid, like the Roman god) to address barriers to recovery and improve walking after stroke. CUped is so called because it compels use of the paretic limb during a movement that resembles pedaling. This project will examine safety, acceptability, and tolerance to CUped, characterize its therapeutic effects, and identify dose-response relationships. Results will provide preliminary data for an R01 to support a randomized controlled trial (RCT). CUped is designed to help stroke survivors recover lower limb movement lost to stroke, thereby improving walking. It is intended to be used as an adjunct to gait training. CUped uses a robotic technology that eliminates compensatory movements that interfere with recovery, compels use of the paretic lower limb, and targets 3 key movement impairments caused by stroke: decreased muscle output from the paretic limb, inappropriate paretic muscle timing, and abnormal interlimb coordination. Exercise is done in sitting which enables high repetition practice. Like walking, CUped requires continuous, reciprocal use of both lower limbs; effects are likely to transfer to walking. The risk-reward profile of this proposal is ideal for an R21, which is an NIH funding opportunity intended to encourage exploratory/developmental research by providing support for the early and conceptual stages of project development. CUped is a novel therapy grounded in a physiologic premise and based on prior observations from our laboratory. The investigators have pilot data suggesting that CUped fulfills its design specifications, and this study will be the first to test its therapeutic effects. In this Stage 1 rehabilitation trial, The investigators will support or quickly refute the hypothesis that CUped is safe, acceptable, and capable of eliciting a therapeutic response in stroke survivors. The investigators will also examine tolerance to CUped and dose-response effects. If our hypotheses are supported, the investigators will be poised to run an RCT to isolate the effects of CUped and compare them to standard care. Future work will investigate physiologic mechanisms underlying the effects of CUped.
Observation of the effect of vibration therapy on the gait of children with cerebral palsy and the analysis of their functional evolution
Spasticity, common after a stroke, aggravates the patient's motor impairment causing pain and limitation in daily activities such as eating, dressing and walking. There are different spasticity treatments, such as botulinum neurotoxin, in the first place. Among the emerging therapies is focal extracorporeal shock wave therapy, consisting of a sequence of sonic (mechanical) impulses with high peak pressure. Systematic reviews highlighted that shock waves effectively improve lower and upper limb spasticity. Moreover, the shock waves therapeutic effect can last up to 12 weeks from the last treatment session. When used to treat stroke spasticity, the shock waves' mechanism of action is poorly detailed. On the one side, shock waves could change the physical properties of the muscular tissue (e.g. viscosity, rigidity). On the other, the shock waves produce a robust mechanical stimulation that massively activates muscle and skin mechanoreceptors (e.g. muscle spindles). This activation would modulate, in turn, the spinal (and supra-spinal) circuits involved in spasticity. To our knowledge, no study investigated the shock waves mechanism of action in stroke upper limb spasticity. Research question: do shock waves exert their therapeutic effect on spasticity by changing the muscle's physical properties or by indirectly modulating the excitability of spinal circuits? Specific aims: To investigate the mechanism of action of shock wave therapy as a treatment of upper limb spasticity after a stroke. Two major hypotheses will be contrasted: shock waves reduce hypertonia 1) by changing the muscle's physical features or 2) by changing the motoneurons excitability and the excitability of the stretch reflex spinal circuits. Shock wave therapy is expected to improve spasticity, thus improving the following clinical tests: the Modified Ashworth Scale (an ordinal score of spasticity) and the Functional Assessment for Upper Limb (FAST-UL, an ordinal score of upper limb dexterity). This clinical improvement is expected to be associated with changes in spastic muscle echotexture assessed with ultrasounds, such as an improvement in the Heckmatt scale (an ordinal score of muscle echotexture in spasticity). Clinical improvement is also expected to be associated with an improvement in the following neurophysiological parameters: a reduction of the H/Mmax ratio (an index of hyperexcitability of the monosynaptic stretch reflex circuit), a decrease in amplitude of the F waves (a neurophysiological signal reflecting the excitability of single/restricted motoneurones) and an increase of the homosynaptic depression (also known as post-activation depression, reflecting the excitability of the transmission between the Ia fibres and motoneurones). Understanding the shock wave mechanism of action will lead to a better clinical application of this spasticity treatment. If the shock waves exert their therapeutic effect by changing the muscle's physical properties, they could be more appropriate for patients with muscle fibrosis on ultrasounds. On the contrary, if the shock waves work on spasticity by indirectly acting on the nervous system's excitability, then a neurophysiology study could be used to preliminary identify the muscle groups with the most significant neurophysiological alterations, which could be the muscles benefitting the most from this treatment.
The aim of the study is to investigate the applicability of virtual reality-mediated functional status assessment of patients diagnosed with stroke. Remote assessment of patients and remote rehabilitation (tele-rehabilitation) has an increasing application area in individuals with chronic neurological diseases. In this study, it was aimed to evaluate the upper extremity and balance functions of stroke patients with the developed software.
This study examines the effects of a transitional care program in stroke patients on self-care behavior, quality of life, and hospital readmission. The research conceptual framework is based on the Transitional Care Model by Naylor. Sixty participants with stroke patients at Charoenkrung Pracharak Hospital will be recruited. These participants are stratified by block randomization using NIHSS score and divided into 2 groups; a control group (n=30) and an intervention group (n=30). The program consisted of 2 phases: 1) Phase I during hospital admission and 2) Phase II following hospital discharge
This randomised controlled experimental type study will be conducted with family members who care for the relatives of hemiplegic patients who are hospitalised in Manisa Merkezefendi and Turgutlu State Hospital Physical Therapy Services.
Multi-center, randomized, sham-controlled, double-blind, longitudinal, experimental clinical study to investigate functional recovery effects on the upper limb in chronic stroke patients and the accompanying neural plasticity mechanisms after the application of a brain-computer interface (BCI)-driven functional electrical stimulation (FES) therapy supported by an assistive device (hand orthosis). All the equipment used during the study will be applied in compliance with the indications and methods of use for which it is authorized. Therefore, the results will not extend the indications for the use of the equipment and will not explicitly target industrial development. The study is non-profit and is aimed at improving clinical practice. The study involves two clinical centers. The promoting center is the Vipiteno Neurorehabilitation Department, Italy. The aggregate experimentation center is the Neurology Department of Hochzirl Hospital, Austria. The University of Essex, United Kingdom is the technology provider and data analysis center.
The goal of this clinical trial is to compare in describeparticipant population. The main question it aims to answer is:By using intelligent portable isokinetic tester and traditional isokinetic tester, isokinetic knee flexor and extensor muscles of stroke patients with hemiplegia were trained respectively, so as to observe and compare the effects of the two treatment methods. In addition, the therapeutic effect of the above two treatments was compared with that of exercise therapy alone. Participants will be divided into three groups: control group, intelligent isokinetic treatment group, and traditional isokinetic treatment group. Participants of both the control group and the two treatment groups received exercise therapy. On the basis of exercise therapy, participants of the intelligent isokinetic treatment group used the intelligent portable isokinetic tester to train the affected knee flexion and extensor muscle, while the participants of traditional isokinetic treatment group used the intelligent portable isokinetic tester to train the affected knee flexion and extensor muscle.
