Effect of acupuncture combined with lower limb gait rehabilitation robot on improving walking function in stroke patients with hemiplegia.

BACKGROUND: No study has yet demonstrated the effect of lower limb gait rehabilitation robot treatment combined with acupuncture on stroke patients. OBJECTIVE: To explore the effect of acupuncture combined with lower limb gait rehabilitation robot on walking function in patients with hemiplegia after stroke. METHODS: Fifty-six patients with hemiplegia after stroke were enrolled and randomly divided into two groups. The control group received regular rehabilitation training and acupuncture therapy; the intervention group was additionally trained by AiWalker-I lower limb gait robot. Both groups received 5 sessions a week for 4 weeks. Walking function parameters were assessed before and after the 4-week treatment. RESULTS: There was no significant difference in all parameters between the two groups in baseline (P > 0.05). After 4 weeks of treatment, all parameters including the effectiveness of functional ambulation category (FAC), time up and go test (TUGT) time, Wisconsin gait scale (WGS) score, walking spatiotemporal parameters were all significantly improved in both groups with a significant better effect in the intervention group (P < 0.05). CONCLUSION: Acupuncture combined with lower limb gait rehabilitation robot training has a positive effect on correction of abnormal gait and improvement of walking ability of hemiplegic patients after stroke.

Influence of hyperbaric oxygen therapy-specialized care on limb motor function and mental state of cerebral infarction patients with hemiplegia.

BACKGROUND: Currently, cerebral infarction (CI) is mainly treated by emergency craniotomy or conservative treatment. However, some studies have questioned the functional recovery of patients after hyperbaric oxygen therapy (HBOT)-specialized care. OBJECTIVE: This paper mainly explores the influence of HBOT-specialized care on limb motor function (LMF) and mental state of CI patients with hemiplegia. METHODS: The medical records of 113 CI patients with hemiplegia treated in our hospital from March 2020 to March 2022 were collected. Of these, 53 received routine care nursing (conventional group) and 60 cases were given HBOT-specialized care (research group). Patient general data, scores of Fugl-Meyer Assessment (FMA), National Institutes of Health Stroke Scale (NIHSS), Self-rating Anxiety/Depression Scale (SAS/SDS) and Barthel Index (BI), and nursing efficiency were comparatively analyzed. RESULTS: The two groups showed comparability in general data. FMA and BI scores were increased in the research group after rehabilitation treatment, higher than the baseline and those of the conventional group, while NIHSS, SAS, and SDS scores were reduced, lower compared with baseline and those of the conventional group. In addition, significantly higher nursing efficiency was determined in the research group. CONCLUSION: HBOT-specialized care has beneficial effects on LMF, mental state, negative emotions and self-care ability of CI patients with hemiplegia and can enhance nursing efficacy, which deserves clinical popularization.

Combined Effects of Transcranial Magnetic Stimulation and Argatroban on Balance Function and Daily Living Activities in Hemiplegic Patients Following Cerebral Infarction.

Objective: This study aimed to investigate the impact of combining transcranial magnetic stimulation (TMS) with argatroban on balance function and activities of daily living in patients with hemiplegia following cerebral infarction (CI). Methods: A retrospective analysis was conducted on the clinical data of 104 patients with hemiplegia after CI who were admitted to our hospital from July 2020 to July 2021. The patients were randomly assigned to either the experimental group (EG) or the control group (CG), with 52 patients in each group. The EG received TMS in combination with argatroban, while the CG received argatroban alone. The Berg Balance Scale (BBS) and modified Barthel index (BI) were used to assess the balance function and activities of daily living in both groups after treatment. Results: After treatment, the EG demonstrated significantly higher BBS and BI scores compared to the CG (P < .001). Additionally, the EG showed significantly improved upper limb and lower limb Functional Ambulation Profile (FAM) scores compared to the CG (P < .05). Conclusions: The combination of TMS and argatroban proves to be an effective approach for enhancing balance function and activities of daily living in hemiplegic patients with CI. Therefore, it is recommended as a valuable rehabilitation treatment for such patients.

Clinical Effects of Acupuncture for Stroke Patients Recovery.

Stroke is assumed as one of the common cerebrovascular diseases that endangers human health and life. Its incidence and mortality rates are high, while survivors (50% to 70%) suffer from different degrees of disability. Hemiplegia is a common disability after stroke, mainly manifested as muscle weakness of the affected side, limb spasm, and limited activity, which severely impacts a patient's daily life. There are various rehabilitation methods for stroke hemiplegia, including modern rehabilitation medicine, motor therapy, acupuncture, and rehabilitation robot. The cost and effect of different rehabilitation methods are not the same. It is the focus to find an economical and effective rehabilitation method. In this paper, 128 stroke patients aged 41 to 73 hospitalized between January 2019 and January 2021 were analyzed. The intervention group used standard physical therapy and traditional acupuncture therapy, and the control group only used standard physical therapy. We used RStudio 1.1.419 (RStudio Corporation) for analysis. Experimental results show that the short-term efficacy of the intervention group is better than that of the control group. The intervention group was better than the control group in recovery from injury during rehabilitation, degree of muscle spasm, self-care ability in daily life, and overall degree of damage. In the long-term efficacy analysis, we can see that with the increase in the number of acupuncture, the efficacy of the intervention group is still better than that of the control group. Compared with physical rehabilitation alone, acupuncture has better short-term, and long-term clinical effects for stroke patients improves motor dysfunction and improves the quality of life and independence of stroke patients. With the increase in the number of acupuncture treatments, the patient's rehabilitation effect will be better.

Effects of Neuromuscular Electrical Stimulation Combined with Repetitive Transcranial Magnetic Stimulation on Upper Limb Motor Function Rehabilitation in Stroke Patients with Hemiplegia.

OBJECTIVE: To investigate the effect of neuromuscular electrical stimulation (NMES) combined with repetitive transcranial magnetic stimulation (rTMS) on upper limb motor dysfunction in stroke patients with hemiplegia. METHODS: A total of 240 stroke patients with hemiplegia who met the inclusion criteria were selected and randomly divided into 4 groups (60 cases in each group): control group, NMES group, rTMS group, and NMES + rTMS group. Before treatment and 4 weeks after treatment, we evaluated and compared the results including Fugl-Meyer assessment of upper extremity (FMA-UE) motor function, modified Barthel index (MBI), modified Ashworth scale (MAS), and motor nerve electrophysiological results among the 4 groups. RESULTS: Before treatment, there was no significant difference in the scores of FMA-UE, MBI, MAS, and motor nerve electrophysiological indexes among the four groups, with comparability. Compared with those before treatment, the scores of the four groups were significantly increased and improved after treatment. And the score of the NMES + rTMS group was notably higher than those in the other three groups. CONCLUSION: NMES combined with rTMS can conspicuously improve the upper extremity motor function and activities of daily life of stroke patients with hemiplegia, which is worthy of clinical application and promotion.

Stratified management of hemiplegic shoulder pain using an integrated care pathway: an 18-year clinical cohort analysis.

PURPOSE: Hemiplegic shoulder pain (HSP) is a common but heterogeneous complication of acquired brain injury. Integrated care pathways (ICPs) can support clinical decision-making, prompting timely intervention to improve quality of care. This 18-year cohort analysis of clinical data presents outcomes from an ICP for management of HSP in an inpatient rehabilitation unit. MATERIALS & METHODS: Consecutive data were extracted for all eligible patients admitted between 2000-2018 (n = 333). Patients were categorised according to presentation pattern ("Floppy-subluxed" (59%), "Painful-stiff" (21%) or Mixed/not categorised(20%)) to help guide early management. Pain was assessed using the Shoulder-Q with pain ratings/10 in three domains: rest, night-time and movement. Patients with pain reduction ≥3 points in any domain were designated 'responders'. RESULTS: Mean baseline pain scores were 4.7 (95%CI 4.5,5.0). They were higher on movement (6.1(5.8,6.3)) than at rest (4.7(4.3, 5.0)) or at night (5.7(5.2,5.9)). Pain reduced significantly in all three domains (p < 0.0001) with a 65% overall response rate and complete resolution of pain 21-41%. There was a significant relationship between category of presentation pattern and management protocol used (X2 = 31.2, p < 0.0001). CONCLUSION: These high pain-response rates compare favourably to the literature (14-27%), suggesting that this stratified and integrated approach to HSP guides more effective management in this heterogeneous clinical presentation.Implications for RehabilitationTwo-thirds of the patients demonstrated a clinically-significant reduction in pain when managed using the integrated care pathway. These results compare favourably with pain resolution rates of well under one-third cited in the literature and suggest that the integrated care pathway leads to reduced pain and improved patient outcomes.Hemiplegic shoulder pain can result from a range of different clinical problems. The diversity of presentation and the range of required treatments are confirmed in this 18-year cohort analysis.Heterogeneity in presentation of HSP poses a challenge for both management and the evaluation of outcome. The results of this study suggest that a stratified approach helps to guide more effective management.

Optimal Multifield Functional Electrical Stimulation Parameters for the "Turn on the Light" Task and Related Upper Limb Kinematics Repeatability in Poststroke Subjects.

OBJECTIVE: To characterize the optimal functional electrical stimulation (FES) parameters that assist the turn on the light task (TOTL) on poststroke participants and to analyze the related upper limb (UL) kinematics repeatability. DESIGN: Cross-sectional study. SETTING: Human movement research center. PARTICIPANTS: Poststroke individuals (N=11) with history of a single unilateral stroke that resulted in a motor control dysfunction of the contralesional UL. INTERVENTIONS: FES based on surface multifield technology applied to the contralesional wrist and finger extensors during the TOTL. MAIN OUTCOME MEASURES: FES outcome metrics (virtual electrodes, stimulation duration, intensity) and kinematic metrics (end-point kinematics [absolute and relative duration, mean and peak velocities, relative instant of peak velocity, index of curvature, number of movement units] and joint kinematics [shoulder, elbow, wrist end position and range of movement]). Outcome measures were assessed 2 times with a 72-hour maximum time interval. CONCLUSION: It was possible to establish reliable FES parameters that assisted the TOTL on poststroke participants. These stimulation parameters led to high to very high repeatability in terms of UL kinematics for most of the cases.

Peony and licorice decoction fumigation treatment for strephenopodia after stroke: Study protocol for a randomized controlled pilot trial.

BACKGROUND: As one of the most common functional disabilities in stroke patients with hemiplegia, poststroke strephenopodia (PSS) seriously affects the life quality of patients, and causes mental and emotional disorders. Some studies have suggested that the traditional Chinese medicine fumigation therapy could be an effective intervention method for patients with PSS. This study aims to investigate the biomechanical effect of the classic prescription peony and licorice decoction (PLD) fumigation treatment for PSS. METHODS/DESIGN: This study is a multicenter, randomized, placebo-controlled, double blind trial. A total of 190 patients with PSS according to the inclusion criteria will be recruited in 3 centers and randomly distributed to either the intervention group or the control group in a 1:1 ratio. The intervention group will receive PLD fumigation treatment, while the control group will receive placebo fumigation treatment. All patients will receive standardized modern rehabilitation treatment according to the "Chinese Guidelines for Stroke Rehabilitation" (2011 version). The primary outcome measure is medial plantar area (Metatarsal 1+ Metatarsal 2 + Heel Medial) generating from the RSSCAN gait system. The secondary outcome measures contain the scores of clinical scales including Berg Balance Scale, Fugl-Meyer Assessment, Modified Ashworth Scale, Barthel Index, and Stroke-Specific Quality of Life Scale. All assessments will be implemented at baseline, 4 weeks after intervention and at the end of 3 months' follow-up. Intention-to-treat analysis and per-protocol analysis will be applied in this trial. DISCUSSION: The results of this study are expected to verify the clinical effect of PLD fumigation treatment for strephenopodia after stroke, and to explore the related biomechanical mechanisms by objective evaluation parameter.

Immediate Effects of Ankle Non-elastic Taping on Balance and Gait Ability in Patients With Chronic Stroke: A Randomized, Controlled Trial.

OBJECTIVE: The purpose of this study was to determine the immediate effects of ankle non-elastic taping on balance and gait ability in patients with chronic stroke. METHODS: Thirty patients (inpatients and outpatients) with stroke were randomly assigned to 2 groups: the non-elastic taping group (n = 15) and the placebo-taping group (n = 15). Patients in the non-elastic taping group received Endura sports taping for their ankle joint, and patients in the placebo-taping group received Endura fix tape for their ankle joint. The Balance System SD assessed balance, and the GAITRite system assessed gait ability. We recorded measurements before and after intervention. RESULTS: The non-elastic taping group showed a significant improvement in static and dynamic standing balance (P ≤ .001) after intervention; in addition, this group showed significant increases in the velocity, cadence, step length, and stride length of gait (P ≤ .001) after intervention. However, the placebo-taping group showed no significant improvements in standing balance and gait ability after intervention (P >.05). Furthermore, significant differences in static and dynamic standing balance, cadence, and velocity were observed between the 2 groups after intervention (P ≤ .001). CONCLUSIONS: Our results demonstrate that the application of ankle non-elastic taping is effective at improving balance and gait abilities in patients with stroke. Ankle non-elastic taping appears to be an effective method to facilitate active rehabilitation in patients with hemiplegia.

Eye-acupuncture with rehabilitation therapy for stroke.

BACKGROUND: Stroke survivors are accompanied by dysfunctions, greatly declining their activities of daily living and bringing burden to families and societies. Although modern rehabilitation therapy has a systematic program in post-stroke motor rehabilitation, numbers of patients still recover slowly. Eye-acupuncture (EA), as an important type of acupuncture, has been widely applied effectively in rehabilitation of stroke for about 50 years. So we combine EA with modern rehabilitation which has achieved successful results. Therefore, we need to adopt an objective and accurate evaluation method to study the effect of this method. METHODS: We aim to design a multi-center, block randomized, parallel control trial to assess the effect of eye-acupuncture combined with rehabilitation training therapy for patients with hemiplegia in the convalescent stage of stroke. 360 patients will be enrolled from 6 centres, with half of them (n = 180) in the control group (routine treatment group) and others (n = 180) in the experimental group (eye-acupuncture combined with routine treatment group). Stratified block randomization will be used in the study and the serial number 001-360 which corresponds to a participant will be assigned to each center randomly. We will use the sequentially sealed envelopes to hide the generating of assignment sequence. The cases of dropouts will be recorded with reasons. And the clinical CRFs will be filled in accurately, completely, and timely for statistical analysis. RESULTS: To verify the clinical effects, we will measure the change of bellows from visit 1 to visit 4. Primary outcomes: activity of daily living (ADL) scales (modified Barthel index); simple Fugl-Meyer motor function score; functional magnetic resonance imaging (fMRI) of the brain in the resting state. SECONDARY OUTCOMES: traditional Chinese medicine (TCM) syndrome score scale; western aphasia battery (WAB); water swallow test; Montreal cognitive assessment (MoCA); growth-associated protein-43 (GAP-43); microtubule-associated protein-2 (MAP-2). CONCLUSION: The results of this study will provide present evidence on assessing effectiveness of EA combined with rehabilitation training for patients with hemiplegia in the convalescent stage of stroke. TRIAL REGISTRATION: This trial has been registrated in Chinese Clinical Trail Registry with the registration number as ChiCTR1900027835 (http://www.chictr.org.cn/).

Effects of auditovisual feedback on eye-hand coordination in children with cerebral palsy.

BACKGROUND: Children with spastic hemiplegic cerebral palsy have deficits in eye-hand coordination. This limits manual actions performed with the affected hand, especially fine motor skills such as grasping and manipulation. Visual-motor integration, grasping skills, and visual perception are collectively involved in eye-hand coordination. AIMS: We investigated the effects of augmented biofeedback training on eye-hand coordination in children with spastic hemiplegic cerebral palsy. METHODS AND PROCEDURES: Forty-five spastic hemiplegic cerebral palsy children (5-8 years old) were included. Children were assigned randomly into three equal groups. One group received traditional physical therapy to facilitate visual-motor integration and grasping skills for 3 months. The second group received augmented biofeedback training. The third group received a combination of augmented biofeedback training and traditional physical therapy. Children were evaluated with the Peabody Developmental Motor Scale (2nd edition) (PDMS-2). Treatment sessions were conducted for 60 min, three times a week, for 3 consecutive months. OUTCOMES AND RESULTS: Children that received augmented biofeedback training alongside traditional physical therapy had significantly improved scores in the Visual-Motor Integration and grasping subtests compared to children that received only one intervention. CONCLUSIONS AND IMPLICATIONS: Augmented biofeedback training alongside physical therapy improved eye-hand coordination in children with spastic hemiplegic cerebral palsy.

Effect of motor imagery combined with physical practice on upper limb rehabilitation in children with hemiplegic cerebral palsy.

INTRODUCTION: Evidence indicates that motor deficits in hemiplegic cerebral palsy (HCP) impair both motor execution and planning. However, current rehabilitation efforts focus mainly on relieving impairments in motor execution. Motor imagery (MI) is a promising method for stimulating neural networks underlying the planning and control of movements. OBJECTIVE: Evaluate the effectiveness of MI combined with physical practice in improving the function of the upper limbs in children with HCP. METHOD: Twenty-four participants, aged 7-14 years were divided into two groups: intervention group (IG) and control group (CG). The IG was subjected to MI training and physical practice twice a week for eight consecutive weeks, while the CG received conventional therapy. Participants were assessed with the Assisting Hand Assessment (AHA) at pre-intervention, post-intervention, and follow up. RESULTS: The results showed improved motor functions in both groups. Analysis using the general linear model (analysis of covariance) and Bonferroni post hoc tests showed significant improvements from pre-intervention to post-intervention in the AHA for the IG. The CG showed non-significant improvement in AHA scores. CONCLUSIONS: These findings suggest that the MI training, combined with the physical practice program used in this study, was effective in improving upper limb function in children with HCP.

Restoration of Upper Limb Function After Chronic Severe Hemiplegia: A Case Report on the Feasibility of a Brain-Computer Interface-Triggered Functional Electrical Stimulation Therapy.

Functional electrical stimulation therapy (FEST) is a state-of-the-art treatment for retraining motor function after neurological injuries. Recent literature suggests that FEST can be further improved with brain-computer interface (BCI) technology. In this case study, we assessed the feasibility of using BCI-triggered FEST (BCI-FEST) to restore upper limb function in a 57-yr-old man with severe left hemiplegia resulting from a stroke 6 yrs before enrollment in the study. The intervention consisted of two blocks of forty 1-hr BCI-FEST sessions, with three sessions delivered weekly. During therapy, a single-channel BCI was used to trigger the stimulation programmed to facilitate functional movements. The measure of the feasibility of the BCI-FEST included assessing the implementation and safety of the intervention. Clinical improvements were assessed using (a) Functional Independence Measure, (b) Action Research Arm Test, (c) Toronto Rehabilitation Institute - Hand Function Test, and (d) Fugl-Meyer Assessment Upper Extremity test. Upon completion of 80 therapy sessions, 14-, 17-, and 18-point changes were recorded on Action Research Arm Test, Fugl-Meyer Assessment Upper Extremity test, and Toronto Rehabilitation Institute - Hand Function Test, respectively. The participant also indicated improvement as demonstrated by his ability to perform various day-to-day tasks. The results suggest that BCI-FEST is safe and viable.

Difference in gait recovery rate of hemiparetic stroke patients according to paralyzed side: A cross-sectional study based on a retrospective chart review.

In Donguibogam, a representative encyclopedic source of knowledge on traditional Korean medicine, left-sided hemiparesis due to stroke is called "Tan" as a sort of "Heyol-Byeong," while right-sided hemiparesis due to stroke is called "Tan" as a sort of "Gi-Byeong." According to the theory of Donguibogam, diseases on the left or right side of the human body must be treated differently. Clinically, the symptoms caused by left and right hemisphere lesions in stroke patients differ, as the functions of the left and right hemispheres differ. Considering these facts, when treating patients in clinical practice, it may be useful to distinguish between diseases on the left or right side according to Donguibogam. This study set out to confirm whether side-dependent gait rehabilitation could be used to treat hemiparetic stroke patients. Gait was selected for analysis, as it is the most important factor in returning stroke patients to daily life.This study conducted a retrospective chart review of stroke patients who satisfied the following criteria: outpatient or inpatient at the Wonkwang University Korean Medicine Hospital in Gwangju (WKUGH) with hemiparesis due to stroke; aged between 19 and 85 years old; with a stroke onset within the past 6 months; having undergone gait analysis (GAITRite) more than twice between September 1, 2017 and June 30, 2018 at the WKUGH, with a minimum 2-week interval between the first and next gait analysis; right-handed stroke patient; able to walk unaided. The spatio-temporal parameters for analysis included the FAP, walking velocity, step length, stance time, and swing time as obtained with GAITRite.In the initial gait analysis, there was no significant difference between the 2 groups in all spatio-temporal parameters. However, in the follow-up gait analysis, the left hemiparesis group showed a significantly higher FAP and faster walking velocity than the right hemiparesis group.This study found a difference in the recovery rate between the left and right hemiparesis groups. Based on this, we suggest that a different treatment strategy for gait rehabilitation can be used according to the paralyzed side.This study was approved by the Institutional Review Board (IRB) of the Wonkwang University Korean Medicine Hospital in Gwangju (WKUGH), Republic of Korea (WKIRB 2018 - 25, November 28, 2018). This trial was registered with the Clinical Research Information Service (CRIS) of the Korea National Institute of Health (NIH), Republic of Korea (KCT0002984).

Rationale and design of the theRapeutic effects of peroneal nerve functionAl electrical stimuLation for Lower extremitY in patients with convalescent poststroke hemiplegia (RALLY) study: study protocol for a randomised controlled study.

INTRODUCTION: Increasing evidence supports the utilisation of functional electrical stimulation (FES) to improve gait following stroke; however, few studies have focused exclusively on its use in the convalescent phase. In addition, its efficacy in patients with a non-Western life style has not been evaluated. METHODS AND ANALYSIS: This is a randomised, controlled, open-label multicentre study, comparing rehabilitation with and without FES. The purpose of our study is to test the hypothesis that the FES system improves walking ability in Japanese patients with hemiplegia during the convalescent phase. Two hundred patients aged 20-85 years who had an initial stroke ≤6 months prior to the enrolment, are in a convalescent phase (after the end of acute phase treatment, within 6 months after the onset of stroke) with functional ambulation classification 3 or 4 and have a hemiplegic gait disorder (drop foot) due to stroke have been recruited from 21 institutions in Japan. The patients are randomised in 1:1 fashion to usual gait rehabilitation or rehabilitation using FES (Walkaide). The trial duration is 8 weeks, and the primary outcome measured will be the change in maximum distance from baseline to the end of the trial, as measured with the 6 min walk test (6-MWT). The 6-MWT is performed barefoot, and the two treatment groups are compared using the analysis of covariance. ETHICS AND DISSEMINATION: This study is conducted in accordance with the principles of the Declaration of Helsinki and the Ethical Guidelines for Medical and Health Research Involving Human Subjects and is approved by the ethics committee of all participating institutions. The published results will be disseminated to all the participants by the study physicians. TRIAL REGISTRATION NUMBER: The University Hospital Medical Information Network-Clinical Studies Registry (UMIN000020604).

The effects of electromyography-triggered neuromuscular electrical stimulation plus tilt sensor functional electrical stimulation training on gait performance in patients with subacute stroke: a randomized controlled pilot trial.

The effects of electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation on ankle dorsiflexion during walking are unclear. This study investigated whether combined electrical stimulation training affects gait performance in patients with stroke. Thirty-six patients were randomly assigned to a control (n = 13), electromyography-triggered neuromuscular electrical stimulation training (single electrical stimulation group, n = 12), or a combined electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation training (combined electrical stimulation group, n = 11) group. Both experimental groups undertook 60-minute interventions for two weeks. All patients' gait performances were evaluated according to walking speed and trunk acceleration during 10-meter walking tests undertaken pre-intervention and at two weeks post-intervention. A wireless triaxial accelerometer measured trunk acceleration, and the root mean square values of the vertical, mediolateral, and anterioposterior planes were calculated from randomly selected 10-step sequences. Compared with baseline, the 10-meter walking tests improved significantly after two weeks in the single and combined electrical stimulation groups. In the combined electrical stimulation group, the 10-meter walking tests scores and root mean square of the mediolateral plane improved significantly compared with those in the control group. Electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation training may improve body perturbation stability and walking quality.

The effect of surface electromyography biofeedback on the activity of extensor and dorsiflexor muscles in elderly adults: a randomized trial.

Surface electromyography-biofeedback (sEMG-B) is a technique employed for the rehabilitation of patients with neurological pathologies, such as stroke-derived hemiplegia; however, little is known about its effectiveness in the rehabilitation of the extension and flexion of several muscular groups in elderly patients after a stroke. Therefore, this research was focused on determining the effectiveness of sEMG-B in the muscles responsible for the extension of the hand and the dorsiflexion of the foot in post-stroke elderly subjects. Forty subjects with stroke-derived hemiplegia were randomly divided into intervention or control groups. The intervention consisted of 12 sEMG-B sessions. The control group underwent 12 weeks (24 sessions) of conventional physiotherapy. Muscle activity test and functionality (Barthel index) were determined. Attending to the results obtained, the intervention group showed a higher increase in the average EMG activity of the extensor muscle of the hand and in the dorsal flexion of the foot than the control group (p < 0.001 in both cases), which was associated with an increase in the patients' Barthel index score (p = 0.006); In addition, Fugl-Meyer test revealed higher effectiveness in the lower limb (p = 0.007). Thus, the sEMG-B seems to be more effective than conventional physiotherapy, and the use of this technology may be essential for improving muscular disorders in elderly patients with physical disabilities resulting from a stroke.

A novel neurocognitive rehabilitation tool in the recovery of hemiplegic hand grip after stroke: a case report.

Stroke has significant physical, psychological and social consequences. Recent rehabilitation approaches suggest that cognitive exercises with dual-task (sensory-motor) exercises positively influence the recovery and function of the hemiplegic hand grip. The purpose of this study was to describe a rehabilitation protocol involving the use of a new neurocognitive tool called "UOVO" for hand grip recovery after stroke. A 58-year-old right-handed male patient in the chronic stage of stroke, presenting with left-sided hemiparesis and marked motor deficits at the level of the left hand and forearm, was treated with the UOVO, a new rehabilitation instrument based on the neurocognitive rehabilitation theory of Perfetti. The patient was evaluated at T0 (before treatment), T1 (after treatment) and T2 (2 months of follow-up). At T2, the patient showed improvements of motor functions, shoulder, elbow and wrist spasticity, motility and performance. This case report explores the possibility of improving traditional rehabilitation through a neurocognitive approach with a dual-task paradigm (including motor and somato-sensory stimulation), specifically one involving the use of an original rehabilitation aid named UOVO, which lends itself very well to exercises proposed through the use of motor imagery. The results were encouraging and showed improvements in hemiplegic hand grip function and recovery. However, further studies, in the form of randomized controlled trials, will be needed to further explore and confirm our results.

Overflow using proprioceptive neuromuscular facilitation in post-stroke hemiplegics: A preliminary study.

Hemiplegia is the classic condition resulting from a stroke. To assist in recovery, the overflow method can be employed to stimulate the affected limb, using the healthy contralateral lower limb (LL) to activate the plegic upper limb (UL) musculature. The aim of this study was to evaluate the immediate effect of overflow using the PNF method on the plegic upper limb muscles of post-stroke individuals in the acute and chronic stages, as well as on the muscles of healthy individuals. A total of 22 individuals participated in the work, comprising 8 healthy individuals (control group), 6 post-stroke acute stage individuals (acute group), and 8 post-stroke chronic stage individuals (chronic group). The participants were assessed using a questionnaire with sections for personal and disease data and application of the ICF scale and the Fugl-Meyer index. The three groups were submitted to electromyographic evaluation, using the posterior deltoid (PD), anterior deltoid (AD), pectoralis major (PM), and external oblique (EO) muscles in four different positions: P1 (resting the UL, with the LL contralateral to the affected limb positioned in diagonal); P2 (resting the UL, with manual resistance in the contralateral LL); P3 (affected UL positioned in diagonal, with manual resistance in the contralateral LL) e P4 (affected UL positioned in diagonal, with fixed point and manual resistance in the contralateral LL). The electromyography results revealed no significant differences between most of the positions for the four muscles evaluated (p > 0.05). However, high clinical relevance (d > 0.8) was found for muscle activation in positions 2 and 4. It could be concluded that for post-stroke individuals in the acute and chronic stages, overflow using PNF effectively increased activation of the PD, AD, PM, and EO muscles in the P2, as well as position 4.

Motor-imagery ability and function of hemiplegic upper limb in stroke patients.

Objectives: We quantitatively examined the motor-imagery ability in stroke patients using a bimanual circle-line coordination task (BCT) and clarified the relationship between motor-imagery ability and motor function of hemiplegic upper limbs and the level of use of paralyzed limbs. Methods: We enrolled 31 stroke patients. Tasks included unimanual-line (U-L)-drawing straight lines on the nonparalyzed side; bimanual circle-line (B-CL)-drawing straight lines with the nonparalyzed limb while drawing circles with the paralyzed limb; and imagery circle-line (I-CL)-drawing straight lines on the nonparalyzed side during imagery drawing on the paralyzed side, using a tablet personal computer. We calculated the ovalization index (OI) and motor-imagery ability (image OI). We used the Fugl-Meyer motor assessment (FMA), amount of use (AOU), and quality of motion (QOM) of the motor activity log (MAL) as the three variables for cluster analysis and performed mediation analysis. Results: Clusters 1 (FMA <26 points) and 2 (FMA ≥26 points) were formed. In cluster 2, we found significant associations between image OI and FMA, AOU, and QOM. When AOU and QOM were mediated between image OI and FMA, we observed no significant direct association between image OI and FMA, and a significant indirect effect of AOU and QOM. Interpretation: In stroke patients with moderate-to-mild movement disorder, image OI directly affects AOU of hemiplegic upper limbs and their QOM in daily life and indirectly influences the motor functions via those parameters.
