Efficacy and safety of using a unilateral lower limb exoskeleton combined with conventional treatment in post-stroke rehabilitation: a randomized controlled trial.

Introduction: The incidence of hemiplegia caused by stroke is high. In particular, lower limb dysfunction affects the daily activities of patients, and lower limb robotic devices have been proposed to provide rehabilitation therapy to improve balance function in this patient population. Objective: To assess the effectiveness of the LiteStepper® unilateral lower limb exoskeleton (ULLE) combined with conventional treatment for balance function training in patients with post-stroke hemiplegia. Methods: This multicenter randomized controlled trial, conducted in the convalescent rehabilitation ward of four hospitals, involved 92 patients in their post-stroke phase. Participants were randomized into an experimental group (EG) or a conventional group (CG). The EG adopted the LiteStepper® ULLE combined with conventional treatment for 21 days. The CG underwent a standard daily rehabilitation routine for 21 days. The Berg Balance Scale (BBS), Functional Ambulation Category scale (FAC), 6-min walk test (6MWT), and Barthel Index (Barthel) were used for evaluations before and after 21 days of rehabilitative training. Results: The BBS scores in EG was significantly elevated compared to CG, exhibiting a profound statistical difference (P< 0.0001). Notably, these disparities persisted at both day 21 (P < 0.0001) and day 14 (P < 0.0047) post-intervention, underscoring the efficacy of the treatment in the EG. The EG demonstrated a markedly greater improvement in BBS scores from pre-rehabilitation to 21 days post-training, significantly outperforming the CG. Furthermore, at both day 14 and day 21, functional assessments including the FAC, 6MWT, and Barthel revealed improvements in both groups. However, the improvements in the EG were statistically significant compared to the CG at both time points: day 14 (FAC, P = 0.0377; 6MWT, P = 0.0494; Barthel, P = 0.0225) and day 21 (FAC, P = 0.0015; 6MWT, P = 0.0005; Barthel, P = 0.0004). These findings highlight the superiority of the intervention in the EG in enhancing functional outcomes. Regarding safety, the analysis revealed a solitary adverse event (AEs) related to the LiteStepper®ULLE device during the study period, affirming the combination therapy's safety profile when administered alongside conventional balance training in post-stroke hemiplegic patients. This underscores the feasibility and potential of incorporating LiteStepper®ULLE into rehabilitation protocols for this patient population. Discussion and significance: The LiteStepper® ULLE combined with conventional treatment is effective and safe for balance function training in patients with post-stroke hemiplegia.

Epilepsy with eyelid myoclonia in a patient with ATP1A3-related neurologic disorder.

We report on an 11 year old Polish girl who experienced paroxysmal episodes with decreased consciousness, (hemi)plegia, movement disorders, slurred speech, dysphagia, and abnormal eye movements. An extensive etiological work-up (brain MRI, EEG, EMG, NCS, toxic, metabolic, infectious, and auto-immune screening) was not conclusive. A genetic analysis with whole-exome sequencing demonstrated a de novo heterozygous mutation in the ATP1A3 gene (c.2232C>G, p.Asn744Lys). A 48 h video-EEG monitoring that was conducted in our unit later confirmed the absence of ictal discharge during an episode of hemidystonia, demonstrating its non-epileptic etiology. However, several discharges of generalized spike waves, which were facilitated by intermittent photic stimulation and eyelid closure were recorded, of which a few were associated with eyelid myoclonia. Taken together, these findings are characteristic of epilepsy with eyelid myoclonia. The clinical picture of this patient partially fulfills the diagnostic criteria of relapsing encephalopathy with cerebellar ataxia as well as alternating hemiplegia of childhood. It is increasingly recognized that the distinct syndromes described with ATP1A3 mutations are overlapping and could be identified in the same patients. Certain variations in ATP1A3 have been linked to an increased risk of developing generalized epilepsy syndromes. We hereby present the second case in the literature of a patient with epilepsy with eyelid myoclonia with an ATP1A3-related neurological disorder.

The relationship between the ratio of the supraspinatus muscle thickness measured by ultrasound imaging and glenohumeral subluxation in stroke patients: a cross-sectional study.

Introduction: Glenohumeral subluxation (GHS) is a common complication in stroke patients with hemiplegia, occurring in approximately 17-81% of cases. This study aims to evaluate the relationship between shoulder muscle thickness and the degree of subluxation using ultrasound imaging. Methods: A cross-sectional study of 61 stroke patients with hemiplegia was conducted, measuring supraspinatus muscle thickness, deltoid muscle thickness, and acromion-greater tuberosity (AGT). Logistic regression and ROC analyses were used. ROC curves, calibration plots, and decision curves were drawn on the training and validation sets. Results: According to logistic regression analysis, the ratio of supraspinatus muscle thickness was statistically significant (OR: 0.80; 95% CI: 0.70-0.92; p < 0.01), and it was an independent factor for evaluating the presence or absence of GHS. An AUC of 0.906 (95% CI, 0.802-1.000) was found in the training set; meanwhile, the AUC in the validation set was 0.857 (95% CI, 0.669-1.000), indicating good performance. According to the training set ROC curve, the most effective statistical threshold was 93%, with a sensitivity of 84% and a specificity of 96%. Discussion: The ratio of supraspinatus muscle thickness is a valuable criterion for evaluating GHS risk, supporting targeted rehabilitation interventions.

A home-based hand rehabilitation platform for hemiplegic patients after stroke: A feasibility study.

Background: Patients with stroke often experience weakened upper limbs, making daily tasks difficult to perform. Although rehabilitation devices are available, patients often relapse post-discharge due to insufficient practice. We present a home-based hand telerehabilitation intervention using the iManus™ platform comprising a sensorized glove, a mobile app for the patients, and a therapist portal for monitoring patient progress. Objectives: This research aimed to examine the feasibility, safety, and effectiveness of a home-based telerehabilitation intervention in improving hand function for individuals with mild stroke. A qualitative approach was also used to explore users' experiences, perceived benefits, and challenges associated with using the platform in a home setting. Methods: In this single-case study, we delivered a hand telerehabilitation intervention to a chronic stroke patient with impaired hand function using the iManus™ platform. The intervention consisted of 40 home sessions over eight weeks. We assessed feasibility through user adherence and feedback obtained using a System Usability Scale (SUS) and a semi-structured interview with the participant and their informal caregiver. Safety was evaluated by monitoring pain levels using the Visual Analog Scale (VAS), and efficacy was determined by observing the changes in the fingers' range of motion using the iManus™ platform and clinical outcomes measures, namely the Fugl-Meyer Assessment (FMA) and Jebsen Taylor Hand Function Test (JTHFT). Results: Our participant completed all the assigned sessions, with each averaging 20 min. Usability scored 77.5 out of 100 on the SUS. User feedback from the interviews revealed improved mobility and control over therapy as benefits, indicating room for improvement in the intervention's adaptability and functionality. During the intervention, the participant noted no pain increase, and the telerehabilitation platform recorded range of motion improvements for all finger and wrist joints, excluding wrist extension. The FMA scores were 43 at T0, 53 at T1, and 56 at T2, while the JTHFT scores were 223 at T0, 188 at T1, and 240 at T2. Conclusions: This single case study demonstrated the preliminary feasibility, safety, and efficacy of a novel home-based hand intervention for stroke survivors. The participant showed improved hand functions, good adherence to the program, and reported satisfaction with the intervention. However, these results are based on a single-case study, and further large-scale studies are needed before any generalization is recommended.

Efficacy of a Four-Week Diagonal Pattern Exercise Program on Trunk and Lower Limb Function in Patients With Stroke-Induced Hemiplegia.

Objective The intended effect of this investigation is to quantify the efficacy of a four-week program of diagonal pattern exercises in managing trunk impairments and improving gait difficulties in hemiplegic stroke subjects. The study aims to measure changes in trunk stability and gait parameters post-intervention, providing insights into the potential therapeutic benefits of these exercises for stroke rehabilitation. Methodology This experimentation approach encompassing before and the follow-up test evaluations was implemented in this investigation. It was conducted at Madha College of Physiotherapy, Chennai, using convenience sampling to recruit 20 stroke subjects meeting specific inclusion criteria. Participants underwent pre-test evaluations for trunk control and gait. They were then divided equally into two groups for a four-week intervention comprising diagonal pattern exercises or single-plane training. Treatment sessions were administered five days per week for 45 minutes each. Posttest evaluations assessed changes in trunk control using the Trunk Impairment Scale (TIS) and gait parameters via the Timed Up and Go (TUG) test. Results Pretest analysis indicated no substantial baseline variations among the experimental and control groups, affirming their suitability for comparison. Posttest analysis of intervention at a 5% significance level revealed that the experimental group demonstrated a statistically significant improvement in trunk control, as measured by the TIS and TUG test, compared to the control group. The paired t-test results showed significant differences in pre- and posttest values within each group, while the unpaired t-test confirmed the superiority of the experimental group's outcomes, with a P-value < 0.05. This improvement is likely due to the effectiveness of the diagonal pattern exercise in enhancing trunk muscle activity and coordination. Conclusions This study concludes that diagonal pattern training is more beneficial for improving trunk musculature control and locomotory ability in chronic cerebrovascular accident subjects. The exercise program's simplicity, minimal risks, and ease of home application after initial therapist supervision make it a promising therapeutic approach.

Comparison of the efficacy of 2 different botulinum toxin injection techniques in gastrocnemius muscle spasticity in hemiplegic patients: A randomized double-blind controlled study.

OBJECTIVE: To compare the efficacy of the innervation zone-targeted injection technique (EUROMUSCULUS/USPRM spasticity approach) and the injection technique along the muscle length. DESIGN: A double-blind randomized controlled trial SETTING: Department of rehabilitation medicine of a medical center PARTICIPANTS: One hundred stroke patients with ankle plantar flexor spasticity. MAIN OUTCOME MEASURES: Modified Ashwort Scale, Modified Tardiue Scale, ankle range of motion measurement and 10 Meter Walk Test were used before and one month after injection. INTERVENTIONS: In addition to conventional rehabilitation, eligible patients were randomly assigned to two groups. The experimental group was injected with botulinum toxin along the length of the muscle, while the control group was injected with the same dose and volume of botulinum toxin 25-35% proximal to the medial head and 20-30% proximal to the lateral head of the gastrocnemius muscle. RESULTS: The study was completed by 60 participants with a mean age of 59.96±12.15 years. Both injection methods were found to be effective on range of motion, spasticity level, ambulation and walking speed. There was no statistically significant difference between injection methods CONCLUSION: Both injection methods of botulinum toxin A produce similar clinical effects.

Explainable machine learning for assessing upper respiratory tract of racehorses from endoscopy videos.

Laryngeal hemiplegia (LH) is a major upper respiratory tract (URT) complication in racehorses. Endoscopy imaging of horse throat is a gold standard for URT assessment. However, current manual assessment faces several challenges, stemming from the poor quality of endoscopy videos and subjectivity of manual grading. To overcome such limitations, we propose an explainable machine learning (ML)-based solution for efficient URT assessment. Specifically, a cascaded YOLOv8 architecture is utilized to segment the key semantic regions and landmarks per frame. Several spatiotemporal features are then extracted from key landmarks points and fed to a decision tree (DT) model to classify LH as Grade 1,2,3 or 4 denoting absence of LH, mild, moderate, and severe LH, respectively. The proposed method, validated through 5-fold cross-validation on 107 videos, showed promising performance in classifying different LH grades with 100%, 91.18%, 94.74% and 100% sensitivity values for Grade 1 to 4, respectively. Further validation on an external dataset of 72 cases confirmed its generalization capability with 90%, 80.95%, 100%, and 100% sensitivity values for Grade 1 to 4, respectively. We introduced several explainability related assessment functions, including: (i) visualization of YOLOv8 output to detect landmark estimation errors which can affect the final classification, (ii) time-series visualization to assess video quality, and (iii) backtracking of the DT output to identify borderline cases. We incorporated domain knowledge (e.g., veterinarian diagnostic procedures) into the proposed ML framework. This provides an assistive tool with clinical-relevance and explainability that can ease and speed up the URT assessment by veterinarians.

Role of Point-of-Care Cerebral Ultrasonography in Determining the Etiology of Post-carotid Endarterectomy Deficit: A Case Report.

Carotid revascularization surgery is notorious for its neurological morbimortality. We report the case of a 74-year-old hypertensive patient, who underwent left internal carotid artery endarterectomy for a 90% stenosis under general anesthesia, presenting in the immediate postoperative period with right hemiplegia without consciousness disorders. Evaluation by cerebral ultrasound at bedside led to suspicion of intracerebral hemorrhage, which was confirmed by cerebral CT scan. The patient was treated by neuroresuscitation measures in the absence of the possibility of surgical intervention. This hemorrhage may be explained by a reperfusion injury due to the loss of cerebral autoregulation of these vessels, the loss of controlling blood pressure, and the use of heparin in vascular surgery. This is a rare but fatal complication with a high mortality rate.

Effect of Gait Training With Non-paretic Knee Immobilization on Lower Limb and Trunk Acceleration in a Post-stroke Hemiparetic Patient: A Case Report.

This case report describes a woman in her fifties who experienced a left-sided atherothrombotic cerebral infarction with lesions in the left corona radiata. The patient exhibited motor paralysis of the right upper and lower limbs. After a 10-day acute hospital stay, she was admitted to a rehabilitation facility for an intensive program of physical, occupational, and speech therapy. By day 17 of the onset, she had achieved independence by walking with a cane. This case was documented to study the effects of gait training with non-paretic knee immobilization on muscle activity and trunk kinematics in post-stroke hemiplegia. Traditional physical therapy was used initially, followed by an intervention phase in which gait training was performed with the non-paretic knee immobilized. This approach was hypothesized to induce beneficial kinematic and muscle activity changes in the paretic limb. The results showed increased muscle activity in the paretic lateral gastrocnemius without compromising trunk stability, suggesting that this method may improve rehabilitation outcomes in similar cases.

In vitro study of ATP1A3 p.Ala275Pro mutant causing alternating hemiplegia of childhood and rapid-onset dystonia-parkinsonism.

Introduction: We previously reported that ATP1A3 c.823G>C (p.Ala275Pro) mutant causes varying phenotypes of alternative hemiplegia of childhood and rapid-onset dystonia-parkinsonism in the same family. This study aims to investigate the function of ATP1A3 c.823G>C (p.Ala275Pro) mutant at the cellular and zebrafish models. Methods: ATP1A3 wild-type and mutant Hela cell lines were constructed, and ATP1A3 mRNA expression, ATP1A3 protein expression and localization, and Na+-K+-ATPase activity in each group of cells were detected. Additionally, we also constructed zebrafish models with ATP1A3 wild-type overexpression (WT) and p.Ala275Pro mutant overexpression (MUT). Subsequently, we detected the mRNA expression of dopamine signaling pathway-associated genes, Parkinson's disease-associated genes, and apoptosisassociated genes in each group of zebrafish, and observed the growth, development, and movement behavior of zebrafish. Results: Cells carrying the p.Ala275Pro mutation exhibited lower levels of ATP1A3 mRNA, reduced ATP1A3 protein expression, and decreased Na+-K+-ATPase activity compared to wild-type cells. Immunofluorescence analysis revealed that ATP1A3 was primarily localized in the cytoplasm, but there was no significant difference in ATP1A3 protein localization before and after the mutation. In the zebrafish model, both WT and MUT groups showed lower brain and body length, dopamine neuron fluorescence intensity, escape ability, swimming distance, and average swimming speed compared to the control group. Moreover, overexpression of both wild-type and mutant ATP1A3 led to abnormal mRNA expression of genes associated with the dopamine signaling pathway and Parkinson's disease in zebrafish, and significantly upregulated transcription levels of bad and caspase-3 in the apoptosis signaling pathway, while reducing the transcriptional level of bcl-2 and the bcl-2/bax ratio. Conclusion: This study reveals that the p.Ala275Pro mutant decreases ATP1A3 protein expression and Na+/K+-ATPase activity. Abnormal expression of either wild-type or mutant ATP1A3 genes impairs growth, development, and movement behavior in zebrafish.

Cerebral palsy in children: A clinical practice review.

Cerebral palsy is a disorder characterized by abnormal tone, posture, and movement. In clinical practice, it is often useful to approach cerebral palsy based on the predominant motor system findings - spastic hemiplegia, spastic diplegia, spastic quadriplegia, extrapyramidal or dyskinetic, and ataxic. The prevalence of cerebral palsy is between 1.5 and 3 per 1,000 live births with higher percentage of cases in low to middle income countries and geographic regions. Pre-term birth and low birthweight are recognized as the most frequent risk factors for cerebral palsy; other risk factors include hypoxic-ischemic encephalopathy, maternal infections, and multiple gestation. In most cases of cerebral palsy, the initial injury to the brain occurs during early fetal brain development. Intracerebral hemorrhage and periventricular leukomalacia are the main pathologic findings found in preterm infants who develop spastic cerebral palsy. The diagnosis of cerebral palsy is primarily based on clinical findings. Early recognition of infants at risk for cerebral palsy as well as those with cerebral palsy is possible based on a combination of clinical history, use of standardized neuromotor assessment and findings on magnetic resonance imaging; however, in clinical practice, cerebral palsy is more reliably diagnosed by 2 years of age. Magnetic resonance imaging scan is indicated to delineate the extent of brain lesions and to identify congenital brain malformations. Genetic testing and tests for inborn errors of metabolism are indicated to identify specific disorders, especially treatable disorders. Because cerebral palsy is associated with multiple associated and secondary medical conditions, its management requires a sustained and consistent collaboration among multiple disciplines and specialties. With appropriate support, most children with cerebral palsy grow up to be adults with good functional abilities.

Comparison of Single Session Auditory Versus Visual Feedback on Performance and Postural Balance in Hemiplegic Children With Cerebral Palsy.

BACKGROUND:  Cerebral palsy (CP) is a pediatric disorder characterized by a motor impairment resulting from a permanent, non-progressive lesion in the brain. Cerebral palsy is marked by movement and postural control impairments, which greatly affect body structure, function, daily activities, and participation. OBJECTIVE: To compare the single-session auditory versus visual feedback on performance and postural balance in children with hemiplegic cerebral palsy. METHOD: The study was a crossover clinical trial involving a group of 25 patients diagnosed with CP hemiplegia, aged between 6 and 12 years, including both genders. Each patient underwent conventional balance therapy followed by either auditory feedback or visual feedback intervention. After a 48-hour wash-out period, they received conventional balance therapy again before undergoing the alternative intervention initially assigned. The Modified Ashworth scale (MAS), pediatric balance scale (PBS), timed one-leg stance, time up and go test (TUG), and center of pressure (CoP) displacements were assessed as the outcome measures before and after the interventions. RESULTS: Based on the one-leg stand test, TUG, and CoP displacement outcome measures results, both interventions improved balance time, speed of movement, and postural stability in children with hemiplegic spastic cerebral palsy (P < 0.05). Moreover, after a single session of the intervention, the visual feedback group demonstrated a significantly greater improvement in the TUG test, one-leg stand test, and CoP displacement compared to the auditory group (P < 0.05). CONCLUSIONS: The results of the study suggest that combining auditory or visual feedback with conventional balance therapy is effective in treating children with hemiplegic spastic cerebral palsy; furthermore, the utilization of visual feedback would be more effective. Further research is needed to determine the long-term effects of visual and auditory feedback on the assessed outcome measures.

Unraveling stroke gait deviations with movement analytics, more than meets the eye: a case control study.

Background: This study aimed to identify and quantify the kinematic and kinetic gait deviations in post-stroke hemiplegic patients with matched healthy controls using Statistical Parametric Mapping (SPM). Methods: Fifteen chronic stroke patients [4 females, 11 males; age 53.7 (standard deviation 12.2) years; body mass 65.4 (10.4) kg; standing height 168.5 (9.6) cm] and 15 matched healthy controls [4 females, 11 males; age 52.9 (11.7) years; body weight 66.5 (10.7) years; standing height 168.3 (8.8) cm] were recruited. In a 10-m walking task, joint angles, ground reaction forces (GRF), and joint moments were collected, analyzed, and compared using SPM for an entire gait cycle. Results: Generally, when comparing the stroke patients' affected (hemiplegic) and less-affected (contralateral) limbs with the control group, SPM identified significant differences in the late stance phase and early swing phase in the joint angles and moments in bilateral limbs (all p < 0.005). In addition, the vertical and anteroposterior components of GRF were significantly different in various periods of the stance phase (all p < 0.005), while the mediolateral component showed no differences between the two groups. Conclusion: SPM was able to detect abnormal gait patterns in both the affected and less-affected limbs of stroke patients with significant differences when compared with matched controls. The findings draw attention to significant quantifiable gait deviations in the less-affected post-stroke limb with the potential impact to inform gait retraining strategies for clinicians and physiotherapists.

Efficacy and safety of deep brain stimulation in mesencephalic locomotor region for motor function in patients with post-stroke hemiplegia: a study protocol for a multi-center double-blind crossover randomized controlled trial.

Background: Deep brain stimulation (DBS) is a potential treatment for improving movement disorder. However, few large-sample studies can reveal its efficacy and safety. This study aims to initially explore the efficacy and safety of DBS in the mesencephalic locomotor region (MLR) on motor function in patients with post-stroke hemiplegia. Methods/design: This multicenter, prospective, double-blind, randomized crossover clinical trial aims to assess the safety and effectiveness of Deep Brain Stimulation (DBS) in the mesencephalic locomotor region (MLR) for patients with moderate to severe post-stroke hemiplegia. Sixty-two patients with stable disease after a year of conservative treatment will be enrolled and implanted with deep brain electrodes. Post-surgery, patients will be randomly assigned to either the DBS group or the control group, with 31 patients in each. The DBS group will receive electrical stimulation 1 month later, while the control group will undergo sham stimulation. Stimulation will be discontinued after 3 and 6 months, followed by a 2-week washout period. Subsequently, the control group will receive electrical stimulation, while the DBS group will undergo sham stimulation. Both groups will resume electrical stimulation at the 9th and 12th-month follow-ups. Post-12-month follow-up, motor-related scores will be collected for analysis, with the Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE) as the primary metric. Secondary outcomes include balance function, neuropsychiatric behavior, fall risk, daily living activities, and quality of life. This study aims to provide insights into the therapeutic benefits of DBS for post-stroke hemiplegia patients. Result/conclusion: We proposed this study for the first time to comprehensively explore the effectiveness and safety of DBS in improving motor function for post-stroke hemiplegia, and provide evidence for DBS in the treatment of post-stroke hemiplegia. Study limitations are related to the small sample size and short study period. Clinical Trial Registration: Clinicaltrials.gov, identifier NCT05968248.

Effect of touch screen tablet use on fine motor functions in children with hemiparetic cerebral palsy: A randomized controlled trial.

BACKGROUND: Cerebral palsy is the most frequent condition affecting the central nervous system and causing large disability. OBJECTIVE: To determine the impact of touch screen tablet upon fine motor functions in children with hemiparesis. METHOD: This was a randomized controlled trial involving 60 children, ranging in age from 5 to 7 years old, randomized into two groups: intervention or control group (30 children per group). Both groups were given 12 consecutive weeks of designed fine motor tasks. Additionally, for thirty minutes, the intervention group was given a fine motor exercise program on a touch screen tablet. Upper limb function, finger dexterity and pinch strength were measured pre and post the recommended treatment program using the quality of upper extremity skill test (QUEST), Nine-Hole Peg Test and Jamar hydraulic pinch gauge, respectively. RESULTS: All outcome measures were equivalent between intervention groups at admission (P > 0.05). Significant improvements were found in all assessed variables within the two groups. Meanwhile, the intervention group had significantly higher improvements (P < 0.05) in finger dexterity, pinch strength, and upper limb function when compared with the control groups. CONCLUSION: Including a touch screen smart tablet application with a specially designed fine motor program is an effective method that helps children with U-CP perform more effectively with their fine motor skills.

Internet + wearable device training effects on limb function recovery and serum neurocytokine content in stroke patients.

BACKGROUND: The traditional method of post-hospital intervention and guidance of stroke patients has some limitations. OBJECTIVE: To investigate the effects of Internet + wearable device training on limb function recovery and the levels of serum neurocytokines (BDNF, NT-3, and NGF) in stroke patients. METHODS: 80 stroke patients with hemiplegia were randomly selected from the Department of Neurorehabilitation, Affiliated Rehabilitation Hospital of Chongqing Medical University. They were divided into a control group and an observation group, with 40 patients in each group. The control group received routine post-hospital follow-up guidance, while the observation group received Internet remote home rehabilitation guidance combined with wearable device training. The interventions were compared between the two groups. RESULTS: At 4 weeks and 12 weeks after discharge, the observation group showed higher scores on the Fugl-Meyer scale (FMA), Berg Balance Scale (BBS), modified Barthel Index (MBI), stride length, gait speed, gait frequency, and higher levels of BDNF, NT-3, and NGF. Additionally, the observation group had lower scores on the Hamilton Anxiety and Depression Scale (HADS) (P < 0.05). CONCLUSIONS: The application of Internet remote home rehabilitation guidance combined with wearable device training in stroke patients with hemiplegia can improve limb function recovery. It effectively increases the levels of BDNF, NT-3, and NGF, promoting the nutritional repair of damaged nerves. These findings hold clinical significance.

Immediate effects of insoles applied to the sound side lower extremity of patients with chronic hemiplegia during walking.

Background: Asymmetric gait patterns are mostly observed in hemiplegic stroke patients. These abnormal gait patterns resulting in abnormal speed, and decreased ability in daily of activity living. Objective: This study aimed to determine the immediate changes in gait parameters and plantar pressure during elevation by wearing an insole on the sound side lower extremity of patients with hemiplegia. Methods: Thirty-six participants were recruited, comprising those with a post-stroke follow-up of ≥3 months and a functional ambulation category score of ≥2. The participants were asked to walk with and without a 1 cm insole in the shoe of their sound side, and the order of wearing or not wearing the insole was randomized. Gait parameters, bilateral gait parameters, and dynamic plantar pressure were measured using the GAITRite Walkway System. Results: Paired t-test was used to examine immediate changes in gait parameters and plantar pressure with and without insoles during walking in the same group. Overall, gait velocity and step length significantly decreased (p < 0.05), whereas step time significantly increased (p < 0.05). The swing phase of the affected sidelower extremities significantly increased (p < 0.05), and the stance phase significantly decreased (p < 0.05). Double-support unloading phase (pre-swing phase) significantly increased (p < 0.05). The changes in plantar pressure were significantly increased in some lateral zones and significantly decreased in the medial zone of the mid-hindfoot, both in terms of pressure per time and peak pressure (p < 0.05). Conclusion: Although this study did not show immediate positive effects on gait parameters and gait cycle, it is expected that sensory input from the sole of the foot through changes in plantar pressure may help improve gait asymmetry and regulate postural symmetry.

[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.

Case report: Gait-induced palilalia in a patient with hemiplegia due to cerebral infarction.

Background: Palilalia is a type of speech characterized by compulsive repetition of words, phrases, or syllables. Several reports have noted that palilalia can occur in response to external verbal stimuli. Here, we report, for the first time, a patient with palilalia induced by gait, which we call "movement-related palilalia." Case presentation: Eleven months after the onset of cerebral infarction sparing the right precentral gyrus and its adjacent subcortical regions, a 63-year-old, left-handed Japanese man was referred for psychiatric consultation because of a complaint of irritability caused by the stress of compulsive repetition of a single meaningless word, "wai." The repetition of a word, palilalia, in this case, was characterized by its predominant occurrence during walking and by its melodic tones. The palilalia during walking disappeared almost completely after 5 months of treatment with carbamazepine 600 mg. Conclusion: Palilalia induced by gait can occur in patients with a history of cerebral infarction. This palilalia during walking may be due to the reorganization of networks in areas nearby or surrounding cerebral infarcts.

Pulmonary Sarcomatoid Carcinoma: What Makes This Rare Lung Cancer So Challenging?

Pulmonary sarcomatoid carcinoma (PSC) is a rare and aggressive subtype of non-small cell lung carcinoma (NSCLC). This case report describes a 55-year-old male with a significant smoking history who initially presented with left hemiplegia. Imaging studies revealed brain metastases and a spiculated parenchymal lung nodule in the left apical region. Histopathological examination confirmed PSC through a CT-guided biopsy. The patient's condition rapidly deteriorated, leading to death before the initiation of planned palliative chemotherapy. This report highlights the diagnostic challenges and poor prognosis associated with PSC, emphasizing the need for further research into effective treatment strategies.
