For pediatric stroke patients, the beneficial effects of LF-rTMS have been already confirmed in a randomized controlled study. However, there is no report of therapeutic application of high-frequency rTMS (HF-rTMS) in this patient population. In this case series study, we introduced HF-rTMS combined with intensive occupational therapy (OT) in two pediatric hemiparetic patients. We studied two children (8- and 9-year-old boys, both right-handed) with post-stroke upper limb hemiparesis (chronic phase). Both patients underwent 22 treatment sessions of HF-rTMS/OT during 15-day hospitalization. The HF-rTMS was applied over the lesional motor cortex at a frequency of 10Hz for 15 minutes in each session. One session of intensive OT consisted of 30-min one-to-one training and 30-min self-exercise. Motor function of the affected upper limb was serially evaluated with Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT), Simple Test for Evaluating hand Function (STEF), and Ten-second Test. Neither of the patients showed any adverse effects. Both patients showed improvement of motor function in the affected upper limb and were able to use the affected upper limb in some activities of daily living. In the two post-stroke pediatric patients, HF-rTMS/OT was safe and improved upper limb muscle function. Confirmation of these effects in a larger population is needed.展开更多

Objectives: The study aimed to analyze the mirror therapy effect on the range of motion and the lower limb functionality in post-stroke hemiparesis subjects. Materials and Methods: Eleven participants with hemiparesis in the lower limb were subjected to the 10 sessions of a MT protocol. The interventions were three times per week per 30 minutes each day. Evaluation of active and passive ankle goniometry (dorsiflexion and eversion movements);Ascent and Descent Ladder Rate (ADLR);Time Up and Go test (TUG test);EFEI scale;and FAAM scale were performed. The data were collected before and after the intervention using MT, and then statistically compared. Results: The MT improved significantly (p < 0.01) the range of motion of the paretic lower limb both evaluated by active and passive ankle goniometry. An increase in the speed of gait and other functional tasks related to the paretic lower limbs were found through the TUG and ADLR tests. It also demonstrated a positive influence on the functionality of the paretic lower limb motor control through the analysis of the scores in the FAAM and EFEI scales. Conclusion: It is concluded that the MT therapy can help the patients with post-stroke hemiparesis in the improvement of several functions. Probably, the mirror therapy would aid in the repair of the injuries in the cortical areas.展开更多

On the other hand, all neurologic complications of balloon test occlusion (BTO) have been reported in 0%-8.3% and especially in 1.6%-1.7% of symptomatic neurologic complications. There are a few reports concerning a seizure related to cerebral angiography and BTO. We report a case of prolonged seizures and left hemiparesis during and after BTO of the right internal carotid artery. The patient showed repeated focal seizures and prolonged left hemiparesis lasting for approximately 2 months. Computed tomography and magnetic resonance imaging demonstrated no abnormal findings. Suspected mechanisms of seizure were a cerebral blood flow change induced by BTO and neurotoxicity of accumulated contrast medium. A combination of prolonged focal seizures and subsequent hemiparesis is a rare complication of BTO, which should be taken into consideration during BTO.展开更多

A representative example is the pronation and supination of the forearm. Hemiparesis visibly demonstrates disparity of diadochokinesia, and clinical quantification is achieved through the use of an ordinal scale, which is inherently subjective. A conformal wearable and wireless inertial sensor equipped with a gyroscope mounted about the dorsum of the hand can objectively quantify diadochokinesia respective of forearm pronation and supination. The objective of the research endeavor was to apply an assortment of machine learning algorithms to distinguish between a hemiplegic affected and unaffected upper limb pair based on diadochokinesia with respect to pronation and supination of the forearm. Performance of the machine learning algorithms, such as the multilayer perceptron neural network, J48 decision tree, random forest, K-nearest neighbors, logistic regression, and naïve Bayes, were evaluated in consideration of classification accuracy and time to develop the machine learning model. The machine learning feature set was derived from the acquired gyroscope signal data. Using the gyroscope signal data from the conformal wearable and wireless inertial sensor the logistic regression and naïve Bayes machine learning algorithms achieved considerable performance capability with respect to both time to converge the machine learning model and classification accuracy for distinguishing between a hemiplegic upper limb pair for diadochokinesia in consideration of pronation and supination.展开更多

Despite initial diagnostic complexities, cerebral angiography-MRI revealed features indicative of CAA. Symptomatic treatment resulted in improvement, but the patient later developed a fatal hematoma. The discussion navigates the intricate therapeutic landscape of repetitive TIAs in the elderly with cardiovascular risk factors, emphasizing the pivotal role of cerebral MRI and meticulous bleeding risk management. The conclusion stresses the importance of incorporating SWI sequences, specifically when suspecting a cardioembolic TIA, as a diagnostic measure to explore and exclude CAA in the differential diagnosis. This case report provides valuable insights into these challenges, highlighting the need to consider CAA in relevant cases.展开更多

In the context of rehabilitation of a hemiplegic ankle, a longitudinal therapy regimen incorporating stretching and then a series of repetitions for raising and lowering the foot of the hemiplegic ankle can be applied over the course of a year. Using a smartphone equipped with an application to function as a wearable and wireless gyroscope platform mounted to the dorsum of the foot by an armband, the initial phase and final phase of a one year longitudinally applied therapy regimen can be objectively quantified and recorded for subsequent machine learning. Considerable classification accuracy is attained to distinguish between the initial phase and final phase by a support vector machine for a one year longitudinally applied hemiplegic ankle therapy regimen based on the gyroscope signal data obtained by a smartphone functioning as a wearable and wireless inertial sensor system. .展开更多

The current study aimed to investigate whether training under the robotic active-assisted mode improves bimanual motor skill learning(biMSkL) more than training under the active mode in stroke patients. Twenty-six healthy individuals(HI) and 23 chronic hemiparetic stroke patients with a detectable lesion on MRI or CT scan, who demonstrated motor deficits in the upper limb, were randomly allocated to two parallel groups. The protocol included a two-day training on a new bimanual cooperative task, LIFT-THE-TRAY, under either the active or activeassisted modes(where assistance decreased in a pre-determined stepwise fashion) with the bimanual version of the REAplan? robotic device. The hypothesis was that the active-assisted mode would result in greater biMSkL than the active mode. The biMSkL was quantified by a speed-accuracy trade-off(SAT) before(T1) and immediately after(T2) training on days 1 and 2(T3 and T4). The change in SAT after 2 days of training(T4/T1) indicated that both HI and stroke patients learned and retained the bimanual cooperative task. After 2 days of training, the active-assisted mode did not improve biMSkL more than the active mode(T4/T1) in HI nor stroke patients. Whereas HI generalized the learned bimanual skill to different execution speeds in both the active and active-assisted subgroups, the stroke patients generalized the learned skill only in the active subgroup. Taken together, the active-assisted mode, applied in a pre-determined stepwise decreasing fashion, did not improve biMSkL more than the active mode in HI and stroke subjects. Stroke subjects might benefit more from robotic assistance when applied "as-needed." This study was approved by the local ethical committee(Comité d'éthique médicale, CHU UCL Namur, MontGodinne, Yvoir, Belgium;Internal number: 54/2010, Eudra CT number: NUB B039201317382) on July 14, 2016 and was registered with ClinicalTrials.gov(Identifier: NCT03974750) on June 5, 2019.展开更多

Methods: Based on the ancient Chinese Daoyin technique, a six-step method was developed including: 1) motion imagination and imitation;2) mental and breathing regulation;3) target point determination;4) motion percussion;5) motion persistence;6) relaxation. Sixty drop-foot patients who suffered from hemiparesis after a stroke were randomly divided into the experimental group and the control group. Functional evaluation including Fugl-Meyer assessment score, Lovett manual muscle test (MMT), active range of motion of the ankle joint and electromyography were performed before and after the training course. The data were analyzed using the statistical software SPSS 12.0. Results: The differences between the two groups were significant. The effectiveness of the six-step group was significantly better than the effectiveness of the control group. Conclusion: The six-step method of the Chinese Daoyin technique is an effective rehabilitation training method for drop-foot in stroke patients with hemiparesis.展开更多
