[Effect of interactive scalp acupuncture on upper limb function in patients with hemiplegia after stroke].

OBJECTIVE: To explore the clinical effect of interactive scalp acupuncture combined with task-oriented mirror therapy on hemiplegia after stroke. METHODS: A total of 86 patients with hemiplegia after stroke were randomly divided into an observation group (43 cases, 2 cases dropped out) and a control group (43 cases, 2 cases dropped out). Both groups received routine treatment and rehabilitation treatment for stroke. The control group was treated with task-oriented mirror therapy, 40 min each time, once a day, 6 days a week. The observation group was treated with interactive scalp acupuncture at ipsilateral upper 1/5 and 2/5 of the parietal and temporal anterior oblique line and upper 1/5 and 2/5 of the parietal and temporal posterior oblique line on the basis of the treatment as the control group, 45 min each time, once a day, 6 days a week. Both groups were treated for 4 weeks. Before and after treatment and in follow-up of 8 weeks after treatment completion, the Fugl-Meyer assessment (FMA) score, modified Ashworth scale (MAS) score, shoulder abduction angle, wrist dorsiflexion angle and N20 latency and amplitude of somatosensory evoked potential were compared between the two groups. RESULTS: After treatment and in follow-up, the FMA scores were increased (P<0.01), the MAS scores were decreased (P<0.01) compared with those before treatment in the two groups; the FMA scores in the observation group were higher than those in the control group (P<0.01), the MAS scores were lower than those in the control group (P<0.01). After treatment and in follow-up, the shoulder abduction angle and wrist dorsiflexion angle was increased (P<0.01), the N20 latency was shortened and amplitude was increased (P<0.01) compared with that before treatment in both groups; the shoulder abduction angle and wrist dorsiflexion angle in the observation group was greater than that in the control group (P<0.01), the N20 latency was shorter than that in the control group (P<0.01), and the N20 amplitude was higher than that in the control group (P<0.01). CONCLUSION: Interactive scalp acupuncture combined with task-oriented mirror therapy can improve upper limb function in patients with hemiplegia after stroke, and reduce the muscular tone of the affected limb.

Comparative effectiveness of high-intensity laser therapy and ultrasound therapy for hemiplegic shoulder pain in stroke patients: a randomized controlled trial".

BACKGROUND: Hemiplegic shoulder pain (HSP) is a prevalent clinical manifestation following stroke, often causing considerable discomfort and disability. Various therapeutic approaches have been developed to address HSP. OBJECTIVES: This study aimed to compare the effectiveness of HILT versus US therapy in alleviating HSP in stroke patients. METHODS: A double-blind randomized controlled trial enrolled stroke patients with HSP within one year post-onset. Participants were randomly assigned to HILT (with sham US) or US therapy (with sham HILT). Both groups received 10-minute sessions of their assigned therapy modality along with daily shoulder range of motion (ROM) exercises 5 times per week over two consecutive weeks. Pain reduction was the primary outcome, with shoulder ROM as secondary outcomes. RESULTS: Thirty patients (11 women, 19 men; mean age: 60.80 ± 11.51 years) were included. After the two-week intervention, significant improvements were observed in pain reduction at rest and during motion in the HILT group, and in pain reduction during motion and shoulder internal rotation in the US group compared to pre-treatment values within each group. However, there was no significant difference between the HILT and US therapy groups in any evaluated parameter. CONCLUSIONS: Comparable efficacy was found between HILT and US therapy in reducing pain and improving shoulder ROM for HSP in stroke patients. Both modalities, when combined with shoulder ROM exercises, offer viable options for managing HSP in this population. Further research with larger sample sizes is needed to validate these findings and explore long-term outcomes.

Effects of Kinesiotaping on upper limb function and daily activities in subacute or chronic stroke survivors: A randomized control study.

BACKGROUND: Impaired upper limb function in stroke survivors is characterized by muscle weakness, increased muscle tone, contracture, or impaired motor control. OBJECTIVE: We aimed to evaluate the effectiveness of Kinesio-taping application for functional recovery on the affected arm and forearm during rehabilitation. METHODS: Forty-one patients eligible for this study were randomly assigned to either the Kinesio-taping group (n = 21), receiving Kinesio-taping intervention and conventional therapy, or control group (n = 20), receiving sham Kinesio-taping intervention and conventional therapy. The whole intervention lasted for 3 weeks. Fugl-Meyer assessment of the upper extremity, Barthel Index, the Stroke Impact Scale, and modified Ashworth scale were measured at 3 time points: baseline, post-treatment (3rd week), and follow-up (6th week). RESULTS: In the Kinesio-taping group, there were significant differences in the upper extremity (p = 0.003), wrist (p = 0.000) and hand (p = 0.000) parts of the Fugl-Meyer assessment of the upper extremity between the three assessment times. On the other hand, the Barthel Index showed significant differences in both groups after therapy. CONCLUSION: Combining conventional rehabilitation with Kinesio-taping intervention may improve functional motor performance of both the proximal and distal parts of the affected upper extremity in stroke survivors, with potential benefits for activity of daily living.

Takayasu arteritis presenting with large cerebral infarction in a 39-year-old Syrian woman: a case report.

Introduction and importance: Takayasu Arteritis (TA) is a rare chronic inflammatory disease of unknown etiology that primarily affects large vessels, such as the aorta and its major branches. The disease typically presents with diverse symptoms, depending on the site and degree of arterial lesions. Delayed diagnosis is common, especially in younger populations. Case presentation: A 39-year-old Syrian female presented with an initial stroke. She had no prior medical history and was otherwise healthy. On examination, she had an absent left radial pulse, a carotid bruit, and muscle weakness. Blood tests showed an elevated ESR and CRP. Computed tomography of the brain revealed a right large cerebral infarction. Multislice computed tomography angiography showed diffuse arterial wall thickening, stenosis, and occlusion of several major vessels, including the left internal carotid artery, right internal carotid artery, and left subclavian artery. Clinical discussion: The patient was diagnosed with TA based on the American College of Rheumatology criteria. She was treated with prednisolone, methotrexate, and aspirin, and her symptoms improved significantly. Conclusion: This case highlights the importance of considering TA in the differential diagnosis of ischemic stroke, especially in young patients with atypical presentations. Early identification and management are essential to preclude critical sequelae.

Results: Key steps in the prototype testing process were divided into (1) Test of the prototype according to the Participatory Design, divided into Who, When, How, and Why the potential user was involved in the study; and (2) Facilitators, barriers and requirements to improve the prototype. Conclusions: The baropodometric insole prototype can be seen as a promising device for monitoring and treating weight-bearing asymmetry.

Effects of radial extracorporeal shock wave therapy on flexor spasticity of the upper limb in post-stroke patients: A randomized controlled trial.

OBJECTIVE: This study aimed to assess the efficacy of radial extracorporeal shock wave therapy in treating upper limb spasticity after a stroke. DESIGN: Randomized controlled trial. SETTING: Zhujiang Hospital of Southern Medical University. SUBJECTS: This study included 95 people with stroke. INTERVENTION: The active (n = 47) and sham-placebo (n = 48) radial extracorporeal shockwave therapy groups received three treatment sessions (every third day). MAIN MEASURES: The Modified Ashworth Scale, Hmax/Mmax ratio, root mean square, co-contraction ratio, mechanical parameters of the muscle and temperature were measured at baseline and days 2, 5 and 8. RESULTS: Among the 135 potential participants screened, 100 were enrolled and allocated randomly, with 95 participants ultimately being included in the intent-to-treat analysis dataset. The active group showed significantly better improvements in upper limb spasticity and muscle function than did the sham-placebo group. Greater improvements in the Modified Ashworth Scale were observed in the active group than in the sham-placebo group (difference, -0.45; 95% CI, -0.69 to -0.22; P < 0.001). Moreover, significant differences in root mean square, co-contraction ratio and Hmax/Mmax ratio were observed between the two groups (all P < 0.001). The mechanical parameters of the biceps muscle were significantly better in the active group than in the sham-placebo group (P < 0.001). The active group had a higher temperature than the sham-placebo group, although the difference was not significant (P = 0.070). CONCLUSIONS: This study revealed that the treatment with extracorporeal shockwave therapy can relieve upper limb spasticity in people with stroke.

Epileptic seizures as an initial symptom for Sturge­Weber syndrome type III: A report of two cases.

Sturge-Weber syndrome (SWS) type III, a rare neurocutaneous disorder, presents diagnostic challenges due to its variable clinical manifestations. The present study focuses on enhancing the understanding of this syndrome by conducting a detailed analysis of two pediatric cases and providing a comprehensive review of the existing literature. The cases, managed at the Children's Hospital Affiliated to Shandong University (Jinan, China), highlight the diverse clinical presentations and successful management strategies for SWS type III. In the first case, a 4-year-old male patient exhibited paroxysmal hemiplegia, epileptic seizures and cerebral angiographic findings indicative of left pia mater and venous malformation. The second case involved a 2.5-year-old male patient presenting with recurrent seizures and angiographic findings on the right side. Both cases underscore the importance of considering epileptic seizures, acquired and transient hemiplegia and cognitive impairments in the diagnosis of SWS type III. The present study provides insights into the effective use of both pharmacological and surgical interventions, drawing from the positive outcomes observed in these cases. The findings emphasize the need for heightened awareness and a meticulous approach in diagnosing and treating SWS type III, contributing to the better management and prognosis of this condition.

Functional Training for Lower Extremities in Stroke Survivors: A Scoping Review.

Engaging in meaningful and repetitive goal-oriented functional tasks can effectively enhance neuroplasticity and facilitate recovery following a stroke. This particular approach has primarily been studied in relation to functional outcomes and has predominantly focused on late subacute and chronic stroke patients. However, there is a lack of information regarding the standardized protocol of lower extremity functional training, its constituent elements, and its impact on motor recovery during the early subacute phase of stroke. The aim of this study was to examine the available evidence related to the intervention protocol of lower extremity functional training in order to identify common training elements and assess their impact on motor and functional outcomes in stroke survivors. A systematic search was conducted on PubMed and Scopus, covering the period from 2000 to 2022. A total of 1786 articles were retrieved and screened based on predefined inclusion criteria. A total of 36 articles were included in this review. The primary findings were classified into categories such as intervention protocols for functional training and their constituent elements, outcome measures utilized, minimal clinically important differences (MCID) reported, and the conclusions drawn by the respective studies. Only a limited quantity of studies reported on the intervention protocol of lower extremity functional training. The majority of these studies focused on the efficacy of functional training for enhancing gait and balance, as evaluated through functional outcome assessments, particularly in the context of chronic stroke patients. In most studies, the evaluation of outcomes was typically based on statistical significance rather than clinical significance. In light of these findings, it is recommended that future studies be conducted during the early subacute phase of stroke to further investigate the impact of functional training on motor outcomes. This will contribute to a broader understanding of the benefits of functional training in facilitating motor recovery in the lower extremities and its clinical significance in stroke survivors.

Evidence quality assessment of acupuncture intervention for stroke hemiplegia: an overview of systematic reviews and meta-analyses.

Objective: Summarize the conclusions of the systematic review/meta-analysis of the clinical efficacy of acupuncture for stroke hemiplegia, and evaluate its methodological quality and the quality of evidence. Methods: Two researchers searched and extracted 8 databases for systematic reviews (SRs)/meta-analyses (MAs), and independently assessed the methodological quality, risk of bias, reporting quality, and quality of evidence of SRs/MAs included in randomized controlled trials (RCTs). Tools used included the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), the Risk of Bias in Systematic (ROBIS) scale, the list of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The search time is from database building to July 2023. Results: A total of 11 SRs/MAs were included, including 2 English literature and 9 Chinese literature, with all study sites in China. AMSTAR-2 evaluation results showed that the methodological quality of 11 articles was rated as very low quality; Based on the ROBIS evaluation results, the SRs/MAs was assessed as a high risk of bias; According to the results of the PRISMA checklist evaluation, most of the SRs/MAs reports are relatively complete; according to GRADE system, 42 outcomes were extracted from the included SRs/MAs for evaluation, of which 1 was rated as high-quality evidence, 14 as moderate-quality evidence, 14 as low-quality evidence, and 13 as very low-quality evidence. Conclusion: The available evidence indicates that acupuncture has certain clinical efficacy in the treatment of stroke hemiplegia. However, there are still some limitations to this study, such as the lower quality of SRs/MAs methodologies and evidence included, and more high-quality studies are needed to verify them.

Complicated epilepsy surgery: importance of balancing benefit and deficit.

The risk-benefit ratio of epilepsy surgery needs careful consideration, is different for each individual and requires a careful, informed dialogue between the person concerned and their medical advisers. We illustrate this process with Virginia, who has had refractory focal epilepsy from age 1 year and a left hemiparesis. At the age of 45 years, we discussed the possibility of epilepsy surgery and went through non-invasive investigations with structural and functional MRI, tractography, scalp video-EEG telemetry, neuropsychological and neuropsychiatric evaluations. This was followed by a decision to carry out intracranial EEG to define the area of seizure onset and its relation to an area of focal cortical dysplasia, eloquent cortex and tracts. We agreed to carry out a focal resection in the knowledge that this would result in a loss of left-hand function. One year later, Virginia is seizure-free on reduced medication. We describe the steps in the process with Virginia's views.

Inhibitory kinesiotaping has no effect on post-stroke spasticity: Prospective, randomised, controlled study.

OBJECTIVE: Motor neuron pool activity is high in spasticity. The effect of inhibitory kinesiotaping (KT) on spasticity is unclear. The aim of this study is to investigate the effect of inhibitory KT on spasticity after stroke. METHODS: Fifty stroke patients with ankle plantarflexor spasticity were randomised to intervention (27) and control (23) groups. Inhibitory KT was applied to the triceps surae muscle in the intervention group and sham KT to the Achilles tendon in the control group. Inhibitory and sham KT were applied for 72 h with a combined conventional rehabilitation programme. Spasticity was assessed at baseline and 72 h after KT using three instruments: Modified Ashworth Scale (MAS), Homosynaptic Post-Activation Depression (HPAD) reflecting the level of motor neuron pool activity, and joint torque as a measure of resistance to passive ankle dorsiflexion. RESULTS: The baseline MAS score, HPAD levels and dorsiflexion torque of the two groups were not significantly different. The change in MAS score was -3.7 ± 17.5 (p = 0.180) in the intervention group and 3.6 ± 33.3 (p = 0.655) in the control group. The change in dorsiflexion torque was -0.3 ± 16.1 kg m (p = 0.539) in the intervention group and 8.0 ± 24.1 kg m (p = 0.167) in the control group. The change in mean HPAD was 8.7 ± 34.7 (p = 0.911) in the intervention group and 10.1 ± 41.6 (p = 0.609) in the control group. CONCLUSIONS: The present study showed that inhibitory KT has no antispastic effect in stroke patients.

An Initial Psychometric Evaluation of a Novel Upper Extremity Pediatric Stroke Hemiplegic Motor Impairment Scale.

BACKGROUND: Our team designed an innovative, observation-based motor impairment measure-the Pediatric Stroke Hemiplegic Motor Impairment Scale (Pedi HEMIs). Here we present the results of a survey describing common practices in the pediatric stroke community and the initial psychometric properties of the upper extremity subscale of the Pedi HEMIs (Pedi HEMIs-UE). METHODS: This is a cross-sectional study whereby participants completed a battery of assessments including the novel Pedi HEMIs-UE. Internal consistency was measured via Cronbach alpha (α). Intraclass correlation (ICC) was used to assess inter-rater reliability (IRR). Concurrent validity was investigated using Pearson or polychoric correlations and simple linear regressions. RESULTS: The study sample consisted of 18 children aged 1.08 to 15 years. Two participants completed two sets of evaluations, totaling 20 data sets. Cronbach α, a measure of internal consistency, was on average 0.91 (range: 0.89 to 0.92). IRR was excellent with the six raters in almost perfect agreement (ICC = 0.91; 95% confidence interval [CI]: 0.83 to 0.96). Pearson correlation coefficient between the Pedi HEMIs-UE and logit Assisting Hand Assessment (AHA)/mini-AHA was -0.938 (95% CI: -0.979 to -0.827, P < 0.001), indicating excellent concurrent validity. CONCLUSIONS: We found excellent feasibility, reliability, and validity of the Pedi HEMIs-UE in a convenience sample of youth with hemiparesis after stroke.

ATP1A3 regulates protein synthesis for mitochondrial stability under heat stress.

Pathogenic variants in ATP1A3, the gene encoding the α3 subunit of the Na+/K+-ATPase, cause alternating hemiplegia of childhood (AHC) and related disorders. Impairments in Na+/K+-ATPase activity are associated with the clinical phenotype. However, it remains unclear whether additional mechanisms are involved in the exaggerated symptoms under stressed conditions in patients with AHC. We herein report that the intracellular loop (ICL) of ATP1A3 interacted with RNA-binding proteins, such as Eif4g (encoded by Eif4g1), Pabpc1 and Fmrp (encoded by Fmr1), in mouse Neuro2a cells. Both the siRNA-mediated depletion of Atp1a3 and ectopic expression of the p.R756C variant of human ATP1A3-ICL in Neuro2a cells resulted in excessive phosphorylation of ribosomal protein S6 (encoded by Rps6) and increased susceptibility to heat stress. In agreement with these findings, induced pluripotent stem cells (iPSCs) from a patient with the p.R756C variant were more vulnerable to heat stress than control iPSCs. Neurons established from the patient-derived iPSCs showed lower calcium influxes in responses to stimulation with ATP than those in control iPSCs. These data indicate that inefficient protein synthesis contributes to the progressive and deteriorating phenotypes in patients with the p.R756C variant among a variety of ATP1A3-related disorders.

Effects of CICARE model combined with traditional Chinese medicine encapsulation on muscle strength and depression levels in hemiplegic patients with sequelae of cerebrovascular disease.

OBJECTIVE: To investigate the impact of the combination of CICARE (C - Connect, I - Introduce, C - Communicate, A - Ask, R - Respond, E - Exit) communication model and traditional Chinese medicine (TCM) poultice on muscle strength and depression levels in patients. METHODS: Patients were divided into three groups: basic treatment group, basic treatment + TCM poultice group, and combined treatment group. Conventional rehabilitation therapy, TCM poultice external application, and the combination of both with the CICARE communication model were applied in the respective groups. Muscle strength (AMA muscle strength grading scale), self-care abilities (Barthel Index), depression symptoms (Hamilton Depression Rating Scale), neurological deficit status (NIHSS score) and serum inflammatory factor levels were assessed at admission, 3 weeks, and 8 weeks of treatment. RESULTS: After 3 and 8 weeks of treatment, the combined treatment group had higher AMA muscle strength scores and improved Barthel Index scores compared to other groups (p < 0.05). Depressive symptoms also improved significantly in the combined treatment group, with lower HDRS scores at 3 and 8 weeks (p < 0.05). After 8 weeks, IL-1, IL-6, and hs-CRP levels decreased in all groups, with the combined treatment group showing the lowest levels (p < 0.05). NIHSS scores decreased significantly in all groups post-intervention, with the combined treatment group showing the greatest improvement (p < 0.05). CONCLUSION: The integration of CICARE communication model with TCM poultice shows notable benefits in enhancing muscle strength, daily living self-care abilities, reducing depression, neurological impairment, and inflammatory factors in post-stroke hemiplegia patients.

Familial hemiplegic migraine in Indian children-a tertiary center experience.

Familial hemiplegic migraine (FHM), an autosomal dominant subtype of hemiplegic migraine, is a channelopathy presenting with severe headache, visual field defect, paresthesia, unilateral motor deficit, encephalopathy, seizures and aphasia. This cross-sectional study was conducted over 10 months in children aged 1-18 years suspected of hemiplegic migraine at a tertiary care pediatric hospital. Fourteen children were screened and five children with genetically confirmed FHM were included. The symptoms in the study population were paroxysmal hemiparesis (5/5), headache (5/5) and focal seizures (1/5). The hemiplegia episodes lasted from 4 h to 7 days. The mean age at the onset of neurological symptoms was 6.8 ± 0.7 years and the mean age at diagnosis was 12.8 ± 1.7 years, with a mean delay of 6.1 ± 1.9 years for the diagnosis. Neuroimaging during acute episodes revealed accentuated gray, white differentiation in the contralateral cerebral hemisphere with mild effacement of sulcal spaces in T2/fluid-attenuated inversion recovery (FLAIR) images. Genetic testing revealed ATP1A2 mutations (FHM2) in 4/5 and SCN1A (FHM3) in 1/5 patients. All of them (5/5) were initiated on oral topiramate and had favorable treatment responses with a mean follow-up duration of 7 ± 1.4 months. Diagnosis of FHM is mainly clinical and can be confirmed by genetic analysis. Perfusion and diffusion-weighted MRI should be considered during acute headache episodes, as it is mostly normal in symptom-free periods. Routine MRI sequences like T1 weighted, T2 weighted, FLAIR and contrast remain normal even during acute attacks.

Case report: unprecedented case of infantile cerebral infarction following COVID-19 and favorable outcome.

The 2019 novel coronavirus, SARS-CoV-2, was highly prevalent in China as of December 2022, causing a range of symptoms, predominantly affecting the respiratory tract. While SARS-CoV-2 infection in children is generally mild, severe cases, especially in infants, are rare. We present a case of a previously healthy 7-month-old infant who developed cerebral infarction and coagulation dysfunction three days after COVID-19 onset. Clinically, the infant had weakness in the left limbs and pinpoint bleeding spots. A cranial magnetic resonance imaging showed ischemic strokes in the right basal ganglia and thalamus. Laboratory tests indicated thrombocytopenia and coagulation dysfunction. Inflammatory cytokines like interleukin-10 were elevated, with increased CD3+, CD4+, and CD8+ T lymphocytes but decreased CD3- CD16+ CD56+ natural killer cells. Treatment included mannitol, dexamethasone, oral aspirin, and vitamins B1 and B6 for reducing intracranial pressure, antiinflammation, anticoagulation, and nerve support, respectively. During the recovery phase, rehabilitation therapy focused on strength training, fine motor skills, and massage therapy. The infant gradually improved and successfully recovered. While rare, such cases can lead to severe complications. These combined efforts were instrumental in achieving significant functional recovery in the patient, demonstrating that even in severe instances of pediatric cerebral infarction due to COVID-19, positive outcomes are attainable with early and comprehensive medical response.

A Multistage Hemiplegic Lower-Limb Rehabilitation Robot: Design and Gait Trajectory Planning.

Most lower limb rehabilitation robots are limited to specific training postures to adapt to stroke patients in multiple stages of recovery. In addition, there is a lack of attention to the switching functions of the training side, including left, right, and bilateral, which enables patients with hemiplegia to rehabilitate with a single device. This article presents an exoskeleton robot named the multistage hemiplegic lower-limb rehabilitation robot, which has been designed to do rehabilitation in multiple training postures and training sides. The mechanism consisting of the thigh, calf, and foot is introduced. Additionally, the design of the multi-mode limit of the hip, knee, and ankle joints supports delivering therapy in any posture and training sides to aid patients with hemiplegia in all stages of recovery. The gait trajectory is planned by extracting the gait motion trajectory model collected by the motion capture device. In addition, a control system for the training module based on adaptive iterative learning has been simulated, and its high-precision tracking performance has been verified. The gait trajectory experiment is carried out, and the results verify that the trajectory tracking performance of the robot has good performance.

A Training Program Using Modified Joystick-Operated Ride-on Toys to Complement Conventional Upper Extremity Rehabilitation in Children with Cerebral Palsy: Results from a Pilot Study.

The pilot study assessed the utility of a training program using modified, commercially available dual-joystick-operated ride-on toys to promote unimanual and bimanual upper extremity (UE) function in children with cerebral palsy (CP). The ride-on-toy training was integrated within a 3-week, intensive, task-oriented training camp for children with CP. Eleven children with hemiplegia between 4 and 10 years received the ride-on-toy training program 20-30 min/day, 5 days/week for 3 weeks. Unimanual motor function was assessed using the Quality of Upper Extremity Skills Test (QUEST) before and after the camp. During ride-on-toy training sessions, children wore activity monitors on both wrists to assess the duration and intensity of bimanual UE activity. Video data from early and late sessions were coded for bimanual UE use, independent navigation, and movement bouts. Children improved their total and subscale QUEST scores from pretest to post-test while increasing moderate activity in their affected UE from early to late sessions, demonstrating more equal use of both UEs across sessions. There were no significant changes in the rates of movement bouts from early to late sessions. We can conclude that joystick-operated ride-on toys function as child-friendly, intrinsically rewarding tools that can complement conventional therapy and promote bimanual motor functions in children with CP.

Human-centered design of a novel soft exosuit for post-stroke gait rehabilitation.

BACKGROUND: Stroke remains a major cause of long-term adult disability in the United States, necessitating the need for effective rehabilitation strategies for post-stroke gait impairments. Despite advancements in post-stroke care, existing rehabilitation often falls short, prompting the development of devices like robots and exoskeletons. However, these technologies often lack crucial input from end-users, such as clinicians, patients, and caregivers, hindering their clinical utility. Employing a human-centered design approach can enhance the design process and address user-specific needs. OBJECTIVE: To establish a proof-of-concept of the human-centered design approach by refining the NewGait® exosuit device for post-stroke gait rehabilitation. METHODS: Using iterative design sprints, the research focused on understanding the perspectives of clinicians, stroke survivors, and caregivers. Two design sprints were conducted, including empathy interviews at the beginning of the design sprint to integrate end-users' insights. After each design sprint, the NewGait device underwent refinements based on emerging issues and recommendations. The final prototype underwent mechanical testing for durability, biomechanical simulation testing for clinical feasibility, and a system usability evaluation, where the new stroke-specific NewGait device was compared with the original NewGait device and a commercial product, Theratogs®. RESULTS: Affinity mapping from the design sprints identified crucial categories for stakeholder adoption, including fit for females, ease of donning and doffing, and usability during barefoot walking. To address these issues, a system redesign was implemented within weeks, incorporating features like a loop-backed neoprene, a novel closure mechanism for the shoulder harness, and a hook-and-loop design for the waist belt. Additional improvements included reconstructing anchors with rigid hook materials and replacing latex elastic bands with non-latex silicone-based bands for enhanced durability. Further, changes to the dorsiflexion anchor were made to allow for barefoot walking. Mechanical testing revealed a remarkable 10-fold increase in durability, enduring 500,000 cycles without notable degradation. Biomechanical simulation established the modularity of the NewGait device and indicated that it could be configured to assist or resist different muscles during walking. Usability testing indicated superior performance of the stroke-specific NewGait device, scoring 84.3 on the system usability scale compared to 62.7 for the original NewGait device and 46.9 for Theratogs. CONCLUSION: This study successfully establishes the proof-of-concept for a human-centered design approach using design sprints to rapidly develop a stroke-specific gait rehabilitation system. Future research should focus on evaluating the clinical efficacy and effectiveness of the NewGait device for post-stroke rehabilitation.

Todd Paralysis in a Pregnant Mother Presenting as Acute Stroke: Case Report.

Todd's paralysis (TP) is relatively uncommon condition that can occur immediately after an epileptic seizure. It is a heterogeneous clinical syndrome that presents with acute-onset neurological findings, such as paralysis, paresthesia, aphasia, hemianopsia, and an altered state of consciousness. This may be accompanied by cytotoxic edema on diffusion MRI. This case illustrates a 28-week pregnant patient with TP who presented with acute stroke-like clinical and radiological findings. The patient was presented to the emergency room with left side weakness following focal onset generalized seizure. Magnetic resonance imaging demonstrated diffusion restriction which led to the initial consideration of acute stroke. However, after the disappearance of the neurologic deficit and the resolution of the diffusion restriction in the control MRI, the diagnosis shifted away from acute stroke to the postictal TP. It is important to keep in mind that TP may mimic acute stroke even in the presence of an acute brain lesion in the brain MRI. The differentiation is necessary as each of them has completely different treatment and etiology.
